I want to create a JDBC Realm for my web app. Since my users are very different from each other i need to have just one table, with the usernames and passwords for the realm, i decided to create a new table in my database called ROLE(oneToOne relationship with the other users table).
This is how my users domain model looks like:
I am following this tutorial [http://blog.gamatam.com/2009/11/jdbc-realm-setup-with-glassfish-v3.html](http://blog.gamatam.com/2009/11/jdbc-realm-setup-with-glassfish-v3.html) but i am stuck, i dont know how to continue.
I will post the configuration i made at the glassfish server and also my file sun.resources.xml so you can correct me if i am making any mistake:
```
<?xml version="1.0" encoding="UTF-8"?>

<property name="driverClass" value="org.apache.derby.jdbc.ClientDriver"/>
</jdbc-connection-pool>
</resources>
```
In the above comfiguration i have a few doubts, I dont really understand what should i ad at Group table and Group name Column.
The tutorial im following says that i should add security roles at the file sun-web.xml, and i wanted to do it but i dont know what to put in the configuratio. This is just what i added to that file but i think it is not correct. Where in that file should i add the role mapping and how should i configure it?
```
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 9.0 Servlet 2.5//EN" "http://www.sun.com/software/appserver/dtds/sun-web-app_2_5-0.dtd">

</jsp-config>
<security-role-mapping>
<role-name> </role-name>
<group-name> </group-name>
</security-role-mapping>
</sun-web-app>
```
The guy of the tutorial said he had not need for a web.xml, but i do need that file. What should i add my web.xml?
This is my first jdbc realm, i am very confused :)

I have Main menu in my app with 4th submenus. I need the user could go to each of the sub menu from other submenu, example sub1-sub2, sub2-sub3, sub3-sub4, sub4-sub1, not sub2-sub4! 
But I don't use navigation and tabbar controllers. I tried to do something like this
[self.view addSubview:sub1.view];
[self.view removeFromSuperview];
but is works really awful. How could I make it better?

In an expert, I'd like to re-use the dialog that Delphi displays to edit a project's library path and for similar purposes:
I found a [hack for using it](http://tondrej.blogspot.com/2006/06/more-subversion.html) (look for TOrderedListEditDlg on the page). As I think [the guy who wrote](https://stackoverflow.com/users/11480/tondrej) the linked article knows what he does I don't have too much hope for a less hacky solution, but who knows... So: Do you know an official interface (most probably OTA) to TOrderedListEditDlg?
PS: I'm aware that it's probably trivial to recreate the whole dialog but I like consistency and the DRY principle.

I need to download an .mp3 audio file from a server to save in my app and play it without downloading, exactly like the screenshot below, with a progress bar for the download (I found this in the App Store). Can anyone help me to do this in my app, with source code?
Any help will be appreciated! Thanks in advance!
I used `NSURLConnection` but it does not really work for me.
Here is the screenshot of what I am trying to do.

I’m trying to create a table in my document that resembles more or less the table in the picture below:
This table is supposed to be stretched horizontally to `\textwidth`. My first attempt with `tabular*` looked like this:
```
\documentclass{scrartcl}
\usepackage[table]{xcolor}
\definecolor{tableShade}{gray}{0.9}
\begin{document}
\rowcolors{3}{tableShade}{white} %% start alternating shades from 3rd row
\noindent\begin{tabular*}{\textwidth}{@{\extracolsep{\fill}}lrrr}
Something & foo & bar & baz \\
Something & foo & bar & baz \\
Something & foo & bar & baz \\
Something & foo & bar & baz \\
Something & foo & bar & baz \\
\end{tabular*}
\end{document}
```
The result was:
Well, the alternate row coloring works but `tabular*` inserts space between columns to stretch the whole table to `\textwidth`. Browsing through my LaTeX companion I found that `tabularx` should be able to do what I want. So I changed my code to look like that:
```
\documentclass{scrartcl}
\usepackage[table]{xcolor}
\usepackage{tabularx}
\definecolor{tableShade}{gray}{0.9}
\begin{document}
\rowcolors{3}{tableShade}{white} %% start alternating shades from 3rd row
\noindent\begin{tabularx}{\textwidth}{Xrrr}
Something & foo & bar & baz \\
Something & foo & bar & baz \\
Something & foo & bar & baz \\
Something & foo & bar & baz \\
Something & foo & bar & baz \\
\end{tabularx}
\end{document}
```
Now, this looks more like it. But `tabularx` ignores the starting row for the coloring and starts with the first row.
Now I’ve run out of ideas. Any suggestions?

I need some help with implementing these formulas. I think I implemented them correctly but for some reason I don't get the expected results:
This is the code for NMI, I, and H functions respectively.
Are the formulas implemented correctly ?
Thanks
```
int totalN = getTotalN(events);
double h1 = H(clusters, totalN);
double h2 = H(events, totalN);
double valueI = I(clusters, events, totalN);
double value_NMI = valueI / (double) ((h1 + h2) / (double) 2);
System.out.println("NMI: " + value_NMI);
static public double I(HashMap<String, ArrayList<String>> clusters, HashMap<String, ArrayList<String>> events, int totalN) {
//store sorted content to contents
Iterator<Map.Entry<String, ArrayList<String>>> it = events.entrySet().iterator();
Iterator<Map.Entry<String, ArrayList<String>>> it2 = clusters.entrySet().iterator();
String key;
ArrayList<String> event;
ArrayList<String> cluster;
double valueI = 0;
while (it.hasNext()) {
Map.Entry<String, ArrayList<String>> mapItem = it.next();
key = mapItem.getKey();
//if cluster doesn't exist
//if(!clusters.containsKey(key)) continue;

common_docs = common_docs + 1;
break;
}
}
}
if (common_docs != 0) valueI = valueI + ( ( common_docs / (float) totalN) * Math.log((common_docs * totalN) / (float) (event.size() * cluster.size())) );

There have been a couple of questions about Hg sub-repo dependencies in the past ([here](https://stackoverflow.com/questions/4786667/mercurial-subrepositories-managing-more-complex-dependency-hierarchies) and [here](https://stackoverflow.com/questions/4457538/does-a-mercurial-subrepository-have-to-be-a-subdirectory-of-the-main-repository)) but the accepted answers don't seem to address the problem for me.
A project of mine has 4 dependencies: A, B, C, D. D is dependent on A, B and C; and B and C are dependent on A:
I want to use Hg sub-repositories to store them so I can track what version of each they rely on. This is because, while I am using A,B,C and D in this project, . Therefore B and C must track what version of A they need independently of D. At the same time, in my application the versions of B and C referenced by a given version of D must always use the same version of A as that referenced by the given version of D (otherwise it will just fall over at runtime). What I really want is to allow them to reference each other as siblings in the same directory - i.e. D's .hgsub would look like the following, and B and C's would look like the first line.
```
..\A = https:(central kiln repo)\A
..\B = https:(central kiln repo)\B
..\C = https:(central kiln repo)\C
```
However this doesn't seem to work: I can see why (it'd be easy to give people enough rope to hang themselves with) but its a shame as I think its the neatest solution to my dependencies. I've read a few suggested solutions which I'll quickly outline and why they don't work for me:
1. Include copies as nested sub-directories, reference these as Hg sub-repositories. This yields the following directory structure (I've removed the primary copies of A, B, C, B\A, C\A as I can accept referencing the copies inside \D instead): project\ (all main project files) project\D project\D\A project\D\B project\D\B\A project\D\C project\D\C\A Problems with this approach: I now have 3 copies of A on disk, all of which could have independent modifications which must be synced and merged before pushing to a central repo. I have to use other mechanisms to ensure that B, C and D are referencing the same version of A (e.g. D could use v1 while D\B could use v2)
2. A variation: use the above but specify the RHS of the .hgsub to point to a copy in the parent copy (i.e. B and C should have the .hgsub below): A = ..\A
Problems with this approach: I still have three copies on disk The first time I clone B or C it will attempt to recursively pull the referenced version of A from "..\A", which may not exist, presumably causing an error. If it doesn't exist it gives no clue as to where the repo should be found. When I do a recursive push of changes, the changes in D\B\A do not go into the shared central repo; they just get pushed to D\A instead. So if I push twice in a row I can guarantee that all changes will have propagated correctly, but this is quite a fudge. Similarly if I do a (manual) recursive pull, I have to get the order right to get the latest changes (i.e. pull D\A before I pull D\B\A)
3. Use symlinks to point folder \D\B\A to D\A etc. Problems with this approach: symlinks cannot be encoded in the Hg repo itself so every time a team member clones the repo, they have to manually/with a script re-create the symlinks. This may be acceptable but I'd prefer a better solution. Also (personal preference) I find symlinks highly unintuitive.
Are these the best available solutions? Is there a good reason why my initial .hgsub (see top) is a pipe-dream, or is there a way I can request/implement this change?
to better explain the wider usage of A,B,C,D

I'm attempting to customise the look of a Button using a 9-patch drawable with no padding defined within in (no pixels on the right or bottom inside the 9-patch editor).
Is there a simple way to apply a 9-patch drawable to a button and maintain the button's default size. For example, when I apply the 9-patch to the Easy button shown below, it is a different size to the other default styled buttons, which share the same layout, except for the 9-patch style.
Mdpi layout:
Hdpi layout:
So basically, is there a way to make the Easy button the same size as Medium and Hard, on both mdpi and hdpi screens, without making a new 9-patch for each density, and working out the correct padding.
Thanks in advance for your help, I can provide more information if required.

I'm working on web application that needs to render a page and make a screenshot on the client (browser) side.
I don't need the screenshot to be saved on the local HDD though, just kept it in RAM and send it to the application server later.
I researched:
1. BrowserShots alike services...
2. Mechanized browsers...
3. wkhtmltoimage...
4. Python WebKit2PNG...
But none of those gives me all I need, which is:
1. Processing at browser side (generate screenshot of page). Don't need to be saved on HDD! Just...
2. ...send image to Server for further processing.
3. Capturing whole page (not only visible part)
Eventually I came upon Google's Feedback Tool (click "feedback" on YouTube footer to see this). It contains [JavaScript for JPG encoding](http://code.google.com/p/closure-library/source/browse/trunk/third_party/closure/goog/jpeg_encoder/jpeg_encoder_basic.js?spec=svn463&r=440) and two other huge scripts which I can't determine what exactly they do...
But it's processed on the Client side - otherwise there would be no point putting this huge JPEG encoder in the code!
Anyone have any idea how did they made it / how I can make it?
Here is an example of the feedback (report a bug on some screens)

var original_param = 'M '+p1.x+' '+p1.y+'L '+p2.x+' '+p2.y;
var path = paper.path(original_param);

I have defined another path attribute for animation:
```
var animation_param={M: p11.x+' '+p11.y, L: p22.x+' '+p22.y}
```
where `p1` and `p2` are points, I do not put their definitions here, since they return the proper values correctly here.
Then I animate the path with the parameters by:
```
path.animate(animation_param, 1000);

I've deployed a couple of app versions which I can't delete now.
I tried to delete it using "[AppEngine](https://appengine.google.com/) 〉Administration 〉Versions"
When I press "delete" to delete version 99:
An attempt to delete a version always causes 500 error:
I've tried to overwrite them with new ones, but it didn't helped. I've tried to delete them a week ago and yesterday but it always fails. I'm afraid that after some time all versions will became undeletable (now I have 2 undeletable versions and deployed versions limit is ≈11).
How am I supposed to delete that versions? Are there alternative ways to delete deployed versions (appcfg wouldn't help)?

In some code I want to choose `n` random numbers in `[0,1)` which sum to `1`.
I do so by choosing the numbers independently in `[0,1)` and normalizing them by dividing each one by the total sum:
```
numbers = [random() for i in range(n)]
numbers = [n/sum(numbers) for n in numbers]
```
My "problem" is, that the distribution I get out is quite skew. Choosing a million numbers not a single one gets over `1/2`. By some effort I've calculated the pdf, and it's not nice.
Here is the weird looking pdf I get for 5 variables:
Do you have an idea for a nice algorithm to choose the numbers, that result in a more uniform or simple distribution?

Hy.
I know that there are no server controls and server-side events, but...:
My app is like an email box and the unread items are bold displayed.
Ok... the bold items are the unread `(isRead==false)`. I want to update the item to `(isRead=true)` without any click.. just before the page is rendered.
How should I do it? Is there a way in ASP.NET MVC or will I have to do it with JQuery?
.
What is the best way to call a method AFTER "View" rendered?
.
Tks, guys!

I would like to be able to design something to what you see when you get an exception in Visual Studio, a sort of window with a line connecting the window to a point in the code window. I've included a picture of this below:
I notice that whenever the code window loses focus, the exception window disappears. When focused, though, I can move the window around, and the arrow continues to point at the target.
How is this being done? Specifically, ?
I'm coding in C# and using Windows Forms.

How can I create a window with an arrow pointing to another window?

I just came across a neat CSS trick. Check out the fiddle...
```
.tooltiptail {
display: block;
border-color: #ffffff #a0c7ff #ffffff #ffffff;
border-style: solid;
border-width: 20px;
width: 0px;
height: 0px;
}
.anothertail {
background-image: url(http://static.jqueryfordesigners.com/demo/images/coda/bubble-tail2.png);
display: block;
height: 29px;
width: 30px;
}
```
```
<div>Cool Trick:
<br />
<div class="tooltiptail"></div>
</div>
<br />
<div>How do I get this effect with only CSS?
<br />
<div class="anothertail"></div>
</div>
```
This creates a little arrow/triangle-like effect, a "tooltip tail". This blows my mind!
Further, is there a way to extend this CSS trick to create an effect as follows:
This is an interesting problem. Can this be done using only CSS, ignoring the shadow for now?

## UPDATE 1
I figured out a solution to my initial question. Here's the fiddle...
[http://jsfiddle.net/duZAx/7/](http://jsfiddle.net/duZAx/7/)
HTML
```
<div style="position: relative;">Cool Trick:<br />
<div class="tooltiptail"></div>
<div class="tooltiptail2"></div>
</div>
```
CSS
```
.tooltiptail {
display: block;
border-color: #ffffff #a0c7ff #ffffff #ffffff;
border-style: solid;
border-width: 20px;
width: 0px;
height: 0px;
}
.tooltiptail2 {
display: block;
border-color: transparent #ffffff transparent transparent;
border-style: solid;
border-width: 18px;
width: 0px;
height: 0px;
position: relative;
left: 4px;
top: -38px;
}
```
Now, how do I exactly mimic the little picture above using pure CSS, including the shadow and having it cross-browser compatible?

I am running a SQL query that only returns a portion of the entire data. In other words, the data is 'framed.' I have an 'ORDER(ORDER BY' part and for whatever reason, that part isn't working all of the time. Sometimes I get what I expect, and other times I don't.
The query:
```
SELECT
*
FROM
(
SELECT
ROW_NUMBER() OVER(ORDER BY [datetime] DESC, timeMicroSec DESC) AS rowNum,
...
FROM
...
WHERE
...
) AS TempTbl
WHERE
rowNum BETWEEN @startRow AND @endRow;
```
The whole data query works when it is not framed and I use an 'ORDER BY' clause at the end. In the image below, the [datetime] column and the [timeMicroSec] column are joined with string concatenation.
As you can see, the ordering is all messed up. Any help would be appreciated.

In the case where my user uploads an excel file with only one worksheet, I want to intelligently use only that worksheet. However, when I pull the schema for this file I see an unexpected worksheet (circled):
The schema is retrieved via:
```
OleDBConnection.GetSchema("Tables")
```
In this case, it looks like the second worksheet is a filter defined by the user to "peg" two columns from scrolling.
: Is it safe for me to ignore worksheets with "$<filter>" appended? Put another way, if I run through all the worksheets, throwing out the "$<filter>" types, and find that there is only one left, is it a reasonable default to use that worksheet? Does anyone have a reference?
Thanks!

I am using blockui for "Wait ... loading" pop up. It is working fine, but has one small issue: the overlay is covering only captured screen, not scroll window. If I scroll right, the width is not fully covered (but height is covered fully).
I have only width has problem.

$(document).ready(function () {
jQuery('#myAlert').click(function () {

I’m building a simple web application consisting of a canvas and elements on the canvas.
The canvas supports the following operations: load, save
The elements support the following operations: move, resize
JavaScript on the web page sends a message to the server for each operation and the server sends an appropriate response.
Note: the arrow between the Canvas and Element objects is supposed to denote that the Canvas object contains a list of Element objects. I didn't have the right symbols for the diagram.
1. An element on the canvas is moved generating an element_moved message.
2. The front controller manages the session and passes the message to the canvas controller with the correct canvas object.
3. The canvas controller inspects the message and sees that it is for an element on the canvas and passes it on to the element controller.
4. The element controller parses the message and updates the appropriate element object directly.
Is this hierarchical arrangement of controllers common place in MVC designs or am I completely missing the point? I've searched for several hours but haven't found any sites which discuss MVC design in more depth than simply returning a page view.
My motivation behind the design was that each object that the client needs to interact with has a controller so that if the interface changes (to support new methods) then the corresponding controller can be updated without impacting the other parts of the design.

I have a date picker control that I use for a data collection application. It is using MvvM data binding. When going through a list of dates (see fig1) it will populate the date picker correctly. Whenever I hit new, the date pickers are nulled out. When I pull up the popup, it selects the month and year from the previous date that was set to. (fig 2) Is there anyway to default the pop up show the current month in the current year?
Note : I would like to keep the selected date to null on a new entry to force some validation.

I'm using Entity Framework 4 as my ORM on a Windows Forms application.
I have a series of UserControls that function as if they were forms or areas inside my MainForm.cs. The reason I did this was to easily interchange what to display in the 'content' block of the form.
So when I click on the buttons (on the left), I .Clear() whatever controls is currently in the 'content' block and add the select form.
Here's the relevant code:
```
private void navigationBar_Click(object sender, EventArgs e)
{
//panelHolder is a regular Winforms Panel control.
panelHolder.Controls.Clear();
switch (sender.ToString())
{
case "alumnos":
var studentForm = new Students.StudentListerForm();
panelHolder.Controls.Add(studentForm);
break;
case "personal":
var personalForm = new Personal.PersonalListerForm();
panelHolder.Controls.Add(personalForm);
break;
case "atendencia":
var atendenciaForm = new Attendance.StudentAttendanceForm();
atendenciaForm.ShowDialog();
break;
case "cursos":
var gradeForm = new Grades.GradeListerForm();
panelHolder.Controls.Add(gradeForm);
break;
case "centralizador":
MessageBox.Show("est");
break;
case "libretas":
Scores.StudentScores scores = new Scores.StudentScores();
panelHolder.Controls.Add(scores);
break;
}
}
```
Now, each UserControl manages it's own creation and usage of the data context. Inside of each of these controls I have code for example:
```
using (GradeRepository repo = new GradeRepository())
{
cmbGrade.DataSource = repo.FindAllGrades();
}
```
And here's the code for GradeRepository:
```
public class GradeRepository : IDisposable
{
ColegioDBV2Entities db = new ColegioDBV2Entities();
public IQueryable<Grade> FindAllGrades()
{
return db.Grades;
}
public void Add(Grade grade)
{
db.AddToGrades(grade);
}
public void SaveChanges()
{
db.SaveChanges();
}
public void Dispose()
{
db.Dispose();
}
}
```
This ensure I use the context, get data, close it and dispose of it.
My problem lies when I click on one of the buttons I told you about up top, the `panelHolder.Controls.Clear();` line fires [ObjectDisposedException](http://msdn.microsoft.com/en-us/library/system.objectdisposedexception.aspx).
I've temporarily solved this by removing the using statements in the relevant areas, so it now looks like:
```
GradeRepository repo = new GradeRepository();
cmbGrade.DataSource = repo.FindAllGrades();
```
Can anybody suggest a correct way to tackle this problem? Will the .Clear() method successfully dispose of any objects, so using a `using` statement is not needed?
Thank you for your time.

We have a .NET 2.0 application using WinForms and Infragistics 7.2. The title bar for our application has what appears to a black bar layered on it which is covering the minimize, maximize and close buttons. The buttons are still there (as evidenced by the hover colouring and tooltips in the screen shot) and still work when you click in the correct location, but the buttons themselves are not visible.
This is only happening on a few Win7 machines, and may be theme related? We have other applications using the same framework/technology running on the same machine, but they don't have this problem. At one point a PC had this problem in a debug build running through VS2010, but an installed release (same source code) didn't. We've tried exporting themes from one PC to the other but the problem doesn't appear to be exported with it.
Any suggestions would be greatly appreciated!

I'm really new to iPhone development and Stack Overflow questions. I've been doing my first app since January.
My app has a memory leak related to SBJsonParser. After some googling I found another [post](https://stackoverflow.com/questions/4983534/iphone-objective-c-memory-leak-with-sbjsonparser) here on stackoverflow. Thanks to the function that Konrad77 posted on his [answer](https://stackoverflow.com/questions/4983534/iphone-objective-c-memory-leak-with-sbjsonparser/4983610#4983610), I changed some lines of my app. But I'm still getting memory leaks. I would appreciate some help. I'm using AsiHttpRequest 1.8 and JSONframework 3.0beta1.
Instruments tell me that the leak is on the following line of MyLists.m for 99.2%:
```
resultObject = [self.model JSONObjectForRequest:request];
```
The other 0.8% goes to the following line of MyLists.m:
```
[self.model.myLists addObject:userData];
```
Both of previous lines are inside listaGetRequestOnResult function. Here you have all related code:
```

I'm at a client site where they have an application which began in SharePoint and is slowly migrating away to a very custom ASP.NET application. Some of their data elements are still hosted within SharePoint lists, two of which currently in question are some "Notes" and "Tasks" (fairly simple data elements in their SharePoint setup, nothing special about them). One of the things I need to be able to do from within ASP.NET is to automatically create some new items for these lists and add them from code.
So far it's pretty easy. I found the existing web part which handled the editing for those items, attached the debugger to it, tracked how it got its values and what it added to the list, etc. However, one of the fields being added to the list item isn't quite as obvious. In the existing web part UI, the field looks like this:
Essentially, it's a field for entering a user from the current Windows domain. The book icon opens a pop-up which allows the user to search for a name, etc. In my current testing, I'm running as local Administrator on a development machine. So I just look for "admin" in the pop-up and it populates the field with "[machine name]\Administrator" as expected. Then, in debugging, the value that gets pulled from the field and entered into the SharePoint list item is "1" as opposed to a name or anything like that.
I assume that "1" is an identifier for the local admin account. Makes sense, after all. But my question is, how can I get that identifier for the current logged-in user in code? I've found code to get the current user's name, but not any kind of numeric (even though it's a string) ID.
Additionally, this wouldn't just be happening inside of an ASP.NET application context. There's also a WPF client application for laptops which would be generating these list items and synchronizing them back to the server when connected. I'm currently operating on the assumption that the client user would be logged in with a proper domain account known to the server.
I imagine this is pretty easy, I just haven't stumbled across what I need quite yet.

I'm currently upgrading an app from Flex 4.1 to 4.5
We've noticed that the Arial font is rendered differently between the two versions when used at small sizes.
Here's a simple app example:
```
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<fx:Style>
@namespace s "library://ns.adobe.com/flex/spark";
@namespace mx "library://ns.adobe.com/flex/mx";
@font-face {
src: url("/assets/fonts/ARIAL.ttf");
fontFamily: arial;
embedAsCFF: true;
}
@font-face {
src: url("/assets/fonts/ARIALBD.ttf");
fontFamily: arial;
embedAsCFF: true;
font-weight: bold;
}
global
{
font-family: arial;
}
</fx:Style>
<s:Label text="Hello world" fontWeight="bold" x="20" y="20" />
</s:Application>
```
When run against the 2 different sdks, here's an image of the font rendering we get:
Note that in 4.5 the font looks slightly squashed.
What's the cause of this, and how do we resolve it?

First here is an screenshot of what is going on:
So how do I get these elements vertically centered?
Here is my HTML and CSS:

<div class="vcenter">
<p>
<a href="http://www.google.com">JimDaniel</a>
<a href="http://www.cnn.com"><img src="icon.png"/></a>
</p>

min-height: 25px;
display: table-cell;
vertical-align: middle;
}
```
Thanks for the help!

What I am trying to achieve is showing a view during a couple of seconds without user intervention. Is the same effect as the ringer volume view that appears when pressing the volume controls on iphone:
I have a scroll view with an image, taping in the image, sound begin to play, another tap and it pauses. I would like to implement the above effect just to inform of the action (showing a play/pause images).
I hope that I have explained the problem perfectly.
Many thanks for your help.

We're having an issue with layered windows and system menus in Delphi 2009. That is, our layered windows (which have no border) have no system menu. When I say system menu, I am referring to the menu you get when clicking an application's icon, right clicking it's title-bar or (in Windows 7, with the addition of the shift key,) right clicking an application in the task-bar:
When you attempt to access the system menu, e.g. by right-clicking on the task-bar icon, of such a layered window, instead the layered window is risen. Why is this? Is there some sort of style to set, or some sort of event to handle?
Here's a hastily made demo showing the issue. It can really be reproduced with any form with a bsNone borderstyle, though.

How is this possible? I configured my iPhone app like this:
I pushed it into the App Store and now Apple says:
> You have indicated that your binary
requires iOS 4.3 or later. Apps that
require iOS 4.3 or later will not be
available to Verizon iPhone users.
Do I have to change the Base SDK to target iPhone 3.0 platform???
How can I do this?
Thx!
ANSWER:
If you leave the default 3.0 value the iOS Deployment Target is not shown/set which means the latest iOS will be selected? This is the xcode4 bug I beleave.

I have created a custom ListActivity that shows a list of skills and buttons next to them as well as a number. The list looks something like this:
The skill names are drawn from a database as are the points (PTS). I need help figuring out how to set the buttons on the side so they are clickable and they increase or decrease their related points column number.
I'll try for the double bonus and ask if anyone knows how I can then retrieve all these values and update the database they are drawn from, possibly on a "Finalize" button at the bottom of the screen.

I examine heterogeneous trees in ANTLR (using ANTLRWorks 1.4.2).
Here is the example of what I have already done in ANTLR.
```
grammar test;
options {
language = java;
output = AST;
}
tokens {
PROGRAM;
VAR;
}
@members {
class Program extends CommonTree {
public Program(int ttype) {
token = new CommonToken(ttype, "<start>");
}
}
}
start
: program var function
// Works fine:
//-> ^(PROGRAM program var function)
// Does not work (described below):
-> ^(PROGRAM<Program> program var function)
;
program
: 'program'! ID ';'!
;
var
: TYPE^ ID ';'!
;
function
: ID '('! ')'! ';'!
;
TYPE
: 'int'
| 'string'
;
ID
: ('a'..'z' | 'A'..'Z')+
;
WHITESPACE
: (' ' | '\t' '\n'| '\r' | '\f')+ {$channel = HIDDEN;}
;
```
Sample input:
```
program foobar;
int foo;
bar();
```
When I use rewrite rule `^(PROGRAM<Program> program var function)`, ANTLR stumbles over and I get AST like this:
Whereas when I use this rewrite rule `^(PROGRAM program var function)` it works:
1. Could anyone explain where am I wrong, please? Frankly, I do not really get the idea of heterogeneous trees and how do I use <…> syntax in ANTLR.
2. What do r0 and r1 mean (first picture)?

The next code is a part of jBitTorrent API for Java a bit modified by me:
`````
if (!torr.saveAs.matches(""))
info.put("name", torr.saveAs);
else
info.put("name", "noDirSpec");
ArrayList files = new ArrayList();
for (int i = 0; i < torr.name.size(); i++) {
SortedMap file = new TreeMap();
file.put("length", (Integer) torr.length.get(i));
// String[] path = ((String) torr.name.get(i)).split("\\");
String[] path = ((String) torr.name.get(i)).split("/");
File f = new File((String)(torr.name.get(i)));
ArrayList pathList = new ArrayList(path.length);
if(f.isFile())
{
pathList.add(path[path.length - 1]);
}
else if(f.isDirectory())
{
// ???
}
```
This is torrent file(s) generation. So the «String[] path» is commented because of «\\» doesn't match linux slashes and generate invalid paths. Specification for multiple files is:
>
And for single file is:
>
So if I will use the previous code for single file here will be generated this torrent:
And torrent files contains:
>
Okay. But how I should generate torrent for directory? The problem is that in unmodified API will be generated files with full path from root. But I need something like this:
And the valid torrent file is:

I've been playing with Huffman Compression on images to reduce size while maintaining a lossless image, but I've also read that you can use predictive coding to further compress image data by reducing entropy.
From what I understand, in the lossless JPEG standard, each pixel is predicted as the weighted average of the adjacent 4 pixels already encountered in raster order (three above and one to the left). e.g., trying to predict the value of a pixel a based on preceding pixels, x, to the left as well as above a :
```
x x x
x a
```
Then calculate and encode the residual (difference between predicted and actual value).
But what I don't get is if the average 4 neighbor pixels aren't a multiple of 4, you'd get a fraction right? Should that fraction be ignored? If so, would the proper encoding of an 8 bit image (saved in a `byte[]`) be something like:
```
public static void Encode(byte[] buffer, int width, int height)
{
var tempBuff = new byte[buffer.Length];
for (int i = 0; i < buffer.Length; i++)
{
tempBuff[i] = buffer[i];
}
for (int i = 1; i < height; i++)
{
for (int j = 1; j < width - 1; j++)
{
int offsetUp = ((i - 1) * width) + (j - 1);
int offset = (i * width) + (j - 1);
int a = tempBuff[offsetUp];
int b = tempBuff[offsetUp + 1];
int c = tempBuff[offsetUp + 2];
int d = tempBuff[offset];
int pixel = tempBuff[offset + 1];
var ave = (a + b + c + d) / 4;
var val = (byte)(ave - pixel);
buffer[offset + 1] = val;
}
}
}
public static void Decode(byte[] buffer, int width, int height)
{
for (int i = 1; i < height; i++)
{
for (int j = 1; j < width - 1; j++)
{
int offsetUp = ((i - 1) * width) + (j - 1);
int offset = (i * width) + (j - 1);
int a = buffer[offsetUp];
int b = buffer[offsetUp + 1];
int c = buffer[offsetUp + 2];
int d = buffer[offset];
int pixel = buffer[offset + 1];
var ave = (a + b + c + d) / 4;
var val = (byte)(ave - pixel);
buffer[offset + 1] = val;
}
}
}
```
I don't see how this really will reduce entropy? How will this help compress my images further while still being lossless?
Thanks for any enlightenment
EDIT:
So after playing with the predictive coding images, I noticed that the histogram data shows a lot of +-1's of the varous pixels. This reduces entropy quite a bit in some cases. Here is a screenshot:

Does anyone know a way to mimic the UIDatePicker and the even more general UIPicker iOS controls in HTML & JavaScript?
 
Does anyone know of a solution like this? I've seen JavaScript mimics of other iPhone/iPad controls, such as the UIPopoverController. I would really like to be able to offer this way of entering dates (compared to solutions like jQuery UI's datepicker). It looks like it would be easy to use both on a mouse scroll-wheel and on the iPad. So, any advice?

Its been like 3 weeks now that I've been seeking help on this site for this simple save/fetch feature using Core Data but I can't get it to work. I keep getting different suggestions from people and change my code accordingly but can never get it working properly.
Its very discouraging that its taken me this long for this simple error yet I did 100x the work in only the week prior to hit. Its really a bummer when learning how to program.
TableView blank by default until user inputs a name string via the + button in nav bar. String entered should add a cell to the view with the name as the title. It should be saved to memory and fetched upon relaunch of application.

I have Eclipse Helios SR1 installed on Windows XP. I am writing/debugging Java code using JDK 1.6.
When I debug and I hit a breakpoint, Eclipse is fast to show me the stacktrace. (See #1 in attached image.)
However, the source code line highlight (light green, see #2 in attached image) is very slow to appear. Oddly, when I first installed Eclipse, this was very fast. Now it is very slow. It takes about 15 seconds to highlight as light green.
Any ideas what is wrong with my Eclipse install/config?
FYI: Very fast processor + 4GB of RAM. Plenty of disk space. I have tried a "Hello, World" test Java project. Just a few lines of code... still the same issue when hitting a vanilla breakpoint.

Alright, I have a problem on my hands. I'm trying to convert my project to a universal app for the iPhone and the iPad. I'm trying to make iPad-specific versions of my XIB files. As it's not possible to `Create iPad version using autoresizing masks` in Xcode 4, I assumed I'd just be able to pop my XIB into Xcode 3's version of IB, and let that do the magic. No dice. Here's the error I get when i try to open the XIB file in IB:
To be honest I don't know where to proceed from here. I guess I could just resize my views manually, but that's quite tedious and I don't really have the time to be doing that. Any ideas?

I have written an action method in the ReservationController class. To get this code to work I should move the GetCoreTab file to the Reservation folder. I do not want to do that since I give the path of the GetCoreTab file in the ReservationController class. I want to give the path, such that the code for the GetCoreTab method would work from the Reservation controller class.
Structure:
Code:
```
public PartialViewResult GetCoreTab()
{
return PartialView("Tabs/GetCoreTab");
}
```
HTML:
```
<a href="<%= Url.Action("GetCoreTab", "Reservation") %>" class="a">
<b>
<div id="home" class="menu">
</div>
</b>
</a>
```
Any ideas?

I'm not sure if this is a glitch/quirk in the latest Firefox and Chrome, but I've got a `<img>` tag that's been encapsulated by an `<a>` tag to turn the image into a link.
The problem arises in that the click box for the link sits below the image. The image is also clickable, but the dead space under the image is clickable as well.
The `<img>` has a left and bottom margin rule applied to it, which I think is what's causing the issue, but I don't understand why... I've also tried using explicit `</img>` closing tags as that didn't solve the issue either.
Internet Explore 8 works as expected! Does not display the issue below. It shows the box below the image, but the dead space is not clickable in IE 8. Which is how I think it should work.
Here's an image to clarify what I mean: 
I've just added a rule to border all `<a>` tags.
And here's the code...
```
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<style type="text/css">
a
{
text-decoration: none;
border: 1px solid #F00;
}
#testimg {
margin-left: 20%;
margin-bottom: 25px;
}
</style>
</head>
<body>
<div><a href="#"><img id="testimg" alt="" src="imgs/landing/popup_sendbtn.png" /></a></div>
</body>
</html>
```
This is driving me crazy! Any help would be appreciated.

Why does the <a> tag sit BELOW an <img> on screen (Firefox 4 + Chrome only!)

App Crashing- Core Data Problem Or Memory Management?

I have the following entities in core data as shown in the figure below.
Questions:
When ever i delete the any one of the entity object at level 2 and do `[context save:&error];` all other objects in Table Entity1 gets the data fault and the app crashes due to not able to read the Entity1 object any more, giving `EXC_BAD_ACCESS` error.
I am using this code
```
for(Entity1 *entity in listOfEntitys)
{
if(entity.Relation1)
[context deleteObject:entity.Relation1];
if(entity.Relation2)
[context deleteObject:entity.Relation2];
if(entity.Relation3)
[context deleteObject:entity.Relation3];
}
[context save:&error];
```
Its not like I have never deleted any object from core data but this is the only place where problem is occurring. Can anyone Help.
Thanks.
PS. I have seen other questions on SO but none has the same kind of situation as i do.
```

(
"<Entity1: 0x4dc3d80> (entity: Entity1; id: 0x4dc2d60 <x-coredata://DF11191D-0BE9-4A63-955D-0A43153290A4/Entity1/p5> ; data: <fault>)",

I have these 4 tables:
This query
```
var query = db.Authors
.Where(x=> x.ItemAuthors
.Any(z=> z.Item.CategoryItems
.Any(b=> b.categoryID == 10)))
.Select(ci=> new
{
authorText = string.Format("{0} ({1})", ci.text,
ci.ItemAuthors.Count()),
authorId = ci.authorID
});
```
Which populates an Authors drop down list which works as expected. The problem is when I try to count the number of items assigned to each author it counts item the author has in the entire items table.
So for example if author one has 10 books total, but only 2 of these books show up in the above query, I still get a count for 10 books. When I bind that same query to a control I get back the correct data, it's just the count operation that won't work correctly.
To reiterate I bound it to a gridview and I only see one book per author, not all of the books the author wrote. So it appears my query should be correct.
@Jon Skeet, I wasn't able to use the `let` operator as I'm conditionally building my query. I solved my problem by using the original query to get the count. Here's how I modified my original `Count()` syntax:
```
var query = authors2.Select(x => new
{
authorText = string.Format("{0} ({1})",x.text, x.ItemAuthors
.Where(qq=> qq.Item.CategoryItems
.Any(xt=> xt.categoryID == 10))
.Count()),
authorId = x.authorID
});
```

I'm using [White](http://white.codeplex.com/) to automate the BDD testing of our C# WPF UI.
My first couple of tests are working well on my development machine (running Windows 7). However, when I try and run the same code on the build server (virtual machine running Windows server 2003 R2) it doesn't work correctly. In both cases the tests are run from the command line and the tests are using the Cuke4Nuke framework. In the case of the server I am accessing the server via Remote Desktop Connection.
The code looks like:
```
var application = Application.Launch("whiteApp.exe");
var initializeOption = InitializeOption.NoCache;
var windowCriteria = SearchCriteria.ByText("whiteApp");
var window = application.GetWindow(criteria, initializeOption);
var criteria = SearchCriteria.ByAutomationId("rightButton");
var button = (Button) window.Get(criteria);
button.click();
```
The problem is that the buttons click event is not fired when it is run on the server. The button can be clicked (using the mouse) if the UI is left open after White has finished executing. One interesting point is that after the click method is run that the button does show evidence of being clicked as in the picture below, in the case of other buttons the mouse over effect is shown.

I've got an existing C# 4 project which I've checked the test coverage for by using TestDriven.Net and the Visual Studio coverage feature, i.e. Test With -> Coverage from the context menu.
The project contains some code I don't want covered, and I've solved that by adding the `[ExcludeFromCodeCoverage]` for those types and methods.
We've just upgraded TeamCity to 6.0.3, and I've added dotCover coverage to the NUnit build step.
I've managed to remove coverage for external assemblies such as NHibernate in the "Filters" section (by explicitly state the assemblies for which I want coverage), but I'm struggling with how to exclude types and methods from covered assemblies.
|
How do I exclude types and methods from being covered by dotCover in TeamCity?

I have a list view which contains some 20 odd items from database along with a two Buttons and an extra TextView as a counter enclosed within linear layout. The two buttons usually for increment and decrement the value in an extra TextView. What i want is when i press button outside the listView should fetch all items along with an value of an extra text. Right now I can fetch Linear layouts and there child items which are visible on screen i.e. out 20 items 10 are visible on screen, so my question is how to fetch the remaining items along with extra Textview values enclosed within linear layout which are not visible which can be viewed when we scroll the Listview?

I'm really at a loss here, I am trying to use the UIViewAnimationOptionTransitionCurlDown on a view that has some transparency, and here is the result (visually), the code is below. What I want is for the transition to happen without the weird shadow. Any insight as to why that shadow is displaying would also be helpful. It only happens during the animation.
```
[UIView transitionWithView:sender
duration:15.0f
options:UIViewAnimationOptionTransitionCurlDown
animations:^{

I'm trying to alter the behaviour of autocomplete a little. I've got a mock up here [http://jsfiddle.net/ekzMN/6/](http://jsfiddle.net/ekzMN/6/) which is producing the desired result (a la chrome address bar) - as pictured below (currently case sensitive).
The problem I'm having is when the autocomplete list is showing and I hover over the items in the list, the input value changes back to the inputted term rather than staying on the adjusted term with autofill. i.e. in the above image it would change from to .
I guess it is a bit of default autocomplete behaviour that I need to overide but I can't work it out. I've tried `focus: false` and `blur: false` but to no avail.
Thanks.

I want to enable drag and drop in my application to be able to create connections between components. That doesn't sound too hard, but the problem is the type of components I want connections between.
The reason I want to be able to make connections is to be able to make a graph and calculate shortest path, etc.
What I have is a ListBox with Components which are placed on a Canvas. The reason I use ListBox is to make the components selectable. I've also made them draggable.
```
<DataTemplate DataType="{x:Type ViewModels:DocumentViewModel}">
<DataTemplate.Resources>
<Converters:GuiSizeConverter x:Key="SizeConverter"/>
</DataTemplate.Resources>
<ListBox ItemsSource="{Binding Components}" SelectedItem="{Binding SelectedItem}" Background="Transparent"
HorizontalAlignment="Left" VerticalAlignment="Top" BorderThickness="0" Margin="0">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<Canvas ClipToBounds="True" Height="{Binding CurrentProject.Height, Converter={StaticResource SizeConverter}}"
Width="{Binding CurrentProject.Width, Converter={StaticResource SizeConverter}}">
<Canvas.Background>
<SolidColorBrush Color="{DynamicResource {x:Static SystemColors.WindowFrameColorKey}}"/>
</Canvas.Background>
</Canvas>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="Background" Value="Transparent" />

</ListBox.ItemContainerStyle>
</ListBox>
</DataTemplate>
```
The tricky thing now though is that it is not the Components in my ViewModel I want to use drag and drop on, but components within those components. To illustrate this better, see the example picture of a train station and tracks below. I have PlaceableComponents (which are the ones that are in the listbox), i.e. the Track and a Station. A Track is built up of TrackSections, which can be regular track sections and electrified tracks sections). A Station is build up of Platforms, which is built up of Tracks which are built up of TrackSections.
So the components(or nodes) I want to connect are the TrackSections, so I want to drag and drop (using right mousebutton) a section onto another section, and this should call a method (command) in my DocumentViewModel (the viewmodel that holds items on the canvas) and not on the sections since the sections doesn't have a clue about other components, nor should they hold the connection.
The goal is to create a list of connections(containing from and to components) which should be able to be rendered ontop of everything as lines, using an adornment layer or similar). I might also add that the components which can be used to create connections all implement a INode interface to be able to identify them.
I hope I described my question and situation clear enough. I can add that I've found plenty of good posts about drag & dropping but I wasn't able to apply any of them to my case, which is why I'm asking here.

I'm porting
I am having source code of Chicken of VNC Mac application which take vnc of any LAN connected mac. I have to do same with iphone app. So while debugging mac source code I am not able to figure out how that mac app establish an authenticated VNC connection?
I have done some progress. Now i am able to connect any LAN connected MAC and can take VNC of it. But i think the way i am doing is wrong. Actually now i am calling unstoppable timer again & again for [conn startTalking] and making RFBConnection with server on every mseconds for uninterrupted connection. Is this is a right way ? But this arise a new problem i cannot scroll my vnc view because on every mseconds screen is refreshing with new RFBConnection. Can any one guide me ?

I'm trying to create a datagrid with grouping and I'm getting display corruption (blank areas) during horizontal scrolling. The issue appears when there is a GroupStyle.ContainerStyle defined. The datagrid should contain 200 rows or more to reproduce the problem.
[Related Microsoft Connect feedback](https://connect.microsoft.com/VisualStudio/feedback/details/677198/render-glitches-in-wpf4-datagrid-with-disabled-virtualization).
Microsoft guy at [social.msdn.com](http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/cf47f2e9-e488-42f0-9407-5a668d5c086f/) pointed out that adding grouping turns off datagrid virtualization. Possibly that's the root of the problem. I removed grouping from my sample and set `VirtualizingStackPanel.IsVirtualizing` to `false` and got exactly the same kind of corruption.
Code to reproduce the problem:
```
<DataGrid ItemsSource="{Binding Source={StaticResource ResourceKey=cvsGoods}}"
CanUserAddRows="False" CanUserReorderColumns="False"
CanUserDeleteRows="False" CanUserResizeRows="False"
CanUserSortColumns="False" AutoGenerateColumns="True">
<DataGrid.GroupStyle>
<GroupStyle>
<GroupStyle.ContainerStyle>
<Style TargetType="{x:Type GroupItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupItem}">
<ItemsPresenter />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GroupStyle.ContainerStyle>
</GroupStyle>
</DataGrid.GroupStyle>
</DataGrid>
```
After several horizontal scrolls to the right and back to the left blank areas appear on the left side. I tried it on WinXP and Win7.
The question is: how to get rid of that bug? Is there any workaround? Any suggestions?

I have implemented a simple Dijkstra's algorithm for finding the shortest path on an .osm map with Java.
The pathfinding in a graph which is created from an .osm file works pretty well. But in case the user's current location and/or destination is not a node of this graph (just raw coordinates) how do we 'link' those coordinates to the graph to make pathfinding work?
The simple straightforward solution "find the nearest to the current location node and draw a straight line" doesn't seem to be realistic. What if we have a situation like on the attached picture? (UPD)
The problem here is that before we start any 'smart' pathfinding algorithms (like Dijkstra's) we 'link' the current position to the graph, but it is just dumb formula (a hypotenuse from Pythagorean theorem) of finding the nearest node in terms of geographical coordinates and this formula is not 'pathinding' - it can not take obstacles and types of nodes into account.
To paraphrase it - how do we find the shortest path between A and B if B is a node in a graph, and A is not a node?
Have you heard of any other solutions to this problem?

I'm trying to get the div `wrapper` to surround all the divs within it so depending on the amount of content the height of `wrapper` will grow.
I guessed that the way of doing this would be to set `height: 100%` but as you can see from the screen grab below, this is not the case.
Where it says 'No :-(' is what having `height: 100%` is doing where ideally I would like `wrapper` to be at the bottom where it says 'Yes' and I have drawn a red line.
Any help is much appreciated.

I'm making a UNIX web-based terminal for learning purposes. So far I have made a text box and the output is being displayed. Sort of like this.
```
<?php
$output = shell_exec('ls');
echo "<pre>$output</pre>";
?>
```
Form
```
<html>
<head>
<link href="/css/webterminal.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
function shell_execute(str)
{
if (str.length==0)
{
document.getElementById("txtOut").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtOut").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","exec.php?q="+str,true);
xmlhttp.send();
}
</script>
</head
<body onLoad="setUser();">
<div class="container">
<h2>UNIX Web Based Terminal 1.0</h2>
<br />
<p><b>output</b></p>
<form>
<span id="User"></span>< <input type="text" class="textbox" onkeyup="shell_execute(this.value)" size="20" />
</form>
<div class="output">
<p><span id="txtOut"></span></p>
</div>
</div>
</body>
</html>
```
But I want it to look as if the page was really a terminal. When I type a command, it should store the result of the shell command, and then append it to a div tag. So as I am typing in commands, it will keep on showing the output. Just like in the UNIX terminal.
How can I append the output of the commands to a div tag?

Now Im customizing title bar of my application. My aim is to add one extra button on title bar. Im my [previous question](https://stackoverflow.com/questions/5571072/how-to-add-an-extra-button-to-the-window-title-bar-so-it-will-be-work-as-standar) people have adviced me the way I can customize non client area. Thats works perfectly except one small thing - ! I can draw glowing in nonclient area but . I also cant find any resource about this subj.
I looked into [this](http://www.codeproject.com/KB/dialog/AeroNonClientAreaButtons.aspx) sample and made my own test app for investigating non client drawing facilities. Screen shot of my app's window:
So you can see that system button glows out of the windows when my is clipped by borderframe.
For example, Skype's window have four custom buttons in title bar and they can "glow" out of the window frame:
Can anybody advise me to find out the way to draw button's glowing out of the window?
Thanks in advance!
Thank you everybody for answers!

I can't configurate Code Contracts in my class. I've followed the documentation and the example but it doesn't work.
I would to insert Code Contracts condition into my interface, here my code
The interface
```
[ContractClass(typeof(ArticleBLLContract))]
public interface IArticleBLL
{
int getArticleNSheet(string IdBox);
IEnumerable<IArticle> getArticleValue(string IdBox, string IdLanguage);
}
```
The Contract Class
```
[ContractClassFor(typeof(IArticleBLL))]
public sealed class ArticleBLLContract : IArticleBLL
{
int IArticleBLL.getArticleNSheet(string IdBox)
{
Contract.Requires<ArgumentOutOfRangeException>(!String.IsNullOrEmpty(IdBox),"IdBox has no valid value");
return default(int);
}
IEnumerable<Base.Article.IArticle> IArticleBLL.getArticleValue(string IdBox, string IdLanguage)
{
Contract.Requires<ArgumentOutOfRangeException>(!String.IsNullOrEmpty(IdBox), "IdBox has no valid value");
Contract.Requires<ArgumentOutOfRangeException>(!String.IsNullOrEmpty(IdLanguage), "IdLanguagehas no valid value");
Contract.Ensures(Contract.Result<IEnumerable<Base.Article.IArticle>>() != null, "Return value is out of Range");
return default(IEnumerable<Base.Article.IArticle>);
}
}
```
The class to apply Contract
```
public class ArticleBLL : IArticleBLL
{
public int getArticlNSheet(string IdBox)
{
try
{
return _Dal...
}
catch (Exception ex)
{
throw ex;
}
}

{
IEnumerable<IArticle> article = null;
try
{
article = _Dal...
return article;
}
catch (Exception ex)
{
throw ex;
}
}
}
```
I've tried to insert a breakpoint in this line
```
Contract.Requires<ArgumentOutOfRangeException>(!String.IsNullOrEmpty(IdBox),"IdBox has no valid value");
```
but when I call the method it never passes here
This is my project configuration
Is there something wrong?
Thank you!

Is it possible to create a "generic" as in "adaptable" routing service, which will NOT have any public methods to call. Instead, you'd be able to call any command, which would then be mapped in the service and will pass it to appropriate end point with simple message transformation where required.
It may be hard to understand and idea might seem a bit crazy (it came from a colleague of mine), but it's clearer if you look at the example:
similar to what's described in [this article](http://mstecharchitect.blogspot.com/2010/04/wcf-40-routing-service-content-based.html), only difference is that our service should not have a "SubmitTimeSheet" public method, in fact it should have no public methods to call. We'd have to "intercept" an incoming call on a much lower level before it returns "Method Not Found" error.
Is this at all possible? The reason for this is obvious: possibility of adding new clients without having to change the code. All we'd have to do is to add a new mapping entry in some sort of config file or even database, e.g.
```
<Client address="newClientAddress" method="DoAnything" transformation="NewClientDoAnything.xslt" endPoint="endPointClientAddress" endPointMethod="endPointClientDoAnything" />
```

I am currently using the VLOOKUP function for excel and I was wondering does the VLOOKUP actually compare cells or does it just use the cell straight across from it?
This is my formula "=VLOOKUP(A2,Sheet3!A2:B1814,2,FALSE)"
As you can see the VLOOKUP function works find for the first product image but it doesnt for the rest of them( it will give #N/A for most of them because the cell in the pic in the right is empty which is ok), but if you look at the picture on the left, cell A4 is the same as cell A3 on the picture on the right and it is still given me #N/A(this is because they are not in the same cells)
So my question is, is there a way for excel to check the table 1(left pic) to see is there a matching name on table2(right pic) by searching the rows?
Thanks

please i have a problem with Map displaying, although, in the simulator it`s displayed well, on the iPhone i see this (the left one is with mode and the right is with mode):
here is some of my code :
```
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
location = newLocation.coordinate;
MKCoordinateSpan span;
if (shouldAdjustZoom) {
//use the manually defined span
span.latitudeDelta=.005;
span.longitudeDelta=.005;
mapRegion.span = span;
}
else {
mapRegion=mapView.region;
mapRegion.center=newLocation.coordinate;
mapView.region=mapRegion;
}
// Apply new coordinates
[mapView setRegion:mapRegion animated:TRUE];
}
```

I opened a project (Visual C# - Windows Forms) and profiled it, and got the "hottest" methods. Now I can't understand the results because the hottest method is "collapsed methods without source". How can i understand what to fix if I can't see the method? What should i do?
Here is a pic so you can understand.

What does this profiling result mean?

Background: I have a winForm app that registers a user in the database based on the user input provided in the form, auto-generates a random password and username for the user, and e-mails the user a link to take an application based on the marketing company selected.
Problem:
I got the bundles listbox to populate w/ autopostback set to true but the bundles listbox populates as soon as you click on an lbcarrier and it doesn't allow you select more than one carrier.
Do you have any ideas on how to allow multiselect with the postback feature on?
Here's a screenshot of the interface:
code on default.aspx:
```
<td class="style1">
Carriers:</td>
<td bgcolor="#ffffff" class="style2">
<asp:ListBox AutoPostback="true" ID="lbCarriers" runat="server" Height="86px" Width="250px">
</asp:ListBox>
</td>
</tr>
<td class="style1">
Bundles:</td>
<td bgcolor="#ffffff" class="style2">
<asp:ListBox ID="bundles" runat="server" Height="86px" Width="250px">
</asp:ListBox>
</td>
</tr>
```
code on default.aspx.vb:
```
Protected Sub lbCarriers_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbCarriers.SelectedIndexChanged
Dim splt() As String
Dim ac1 As Array
bundles.Items.Clear()
Dim item As ListItem = lbCarriers.SelectedItem
splt = item.ToString().Split("|")
ac1 = proxy.GetContractingBundles("test", "test", Trim(splt(0)))
For Each Pitem In ac1
bundles.Items.Add(Trim(splt(2)) & " | " & Pitem.FormBundleName)
Next
End Sub
```
Thanks for looking!

According to [a poll here on StackOverflow](https://stackoverflow.com/questions/6166/any-good-php-ide-preferably-free-or-cheap), is the best PHP IDE available. This is all fine and good, except for one thing: It appears to be terrible at checking syntax. I'm sure I must be doing something wrong?
I've previously used , which is a great program, but I've only got version 2007, and it doesn't support xDebug (I'd have to buy the new version if I wanted that). So I thought I'd try the much vaunted (and free) NetBeans.
But, as far as I can tell, it's syntax checking is . For example: Note how the same file is handled by the two different IDEs.
First :
Pretty obvious where the problem is, right?
Then :
Here there is nothing but a vague error message at the very bottom of the class, and it's not even near the function causing the error(!).
Is it possible to get better syntax checking in NetBeans? I'm presuming there must be a way, and I'm just being really dumb.
If this is not possible in NetBeans, what other free IDEs are available that have this level of syntax checking?
Thanks for any help.
---
Some people have suggested as a replacement, so I thought I'd test it.
It too correctly recognises the syntax error. (Makes me wonder if NetBeans is bugged.) I may just switch to Eclipse. Are there any other IDEs people think are worth trying?

I have a nine-patch png that I'm using as a popup bubble. It looks like this:
I'm putting it in an TextView of width fill_parent so the bubble expands the width of the screen. As one might expect, the pointer at the top is then centered horizontally in the middle of the screen.
What is the easiest way to adjust the location of the pointer so that it's, say, 5/8ths of the way over from the left instead of centered?
I can re-cut the png if necessary.
Cubic has a very simple solution to the problem that I can't believe I missed. It works very effectively for my current problem. However, one downside with this solution is that it can't be adjusted on the fly. If I need to put the pointer in one place for one view, but a different place for another view, I need to cut two different PNGs. Is there a solution that can be adjusted at runtime?

My app is in the App Store and I had pulled it up so I can share the link with someone. I looked at the languages and saw something really strange.
The app was listed as localized for several languages which I didn't use. I don't even know what half of those languages sound like.
Here's a screenshot:

Are all apps localized to, say, Serbian by default?

I test the exceptions interception, so, I don't need that Visual Studio breaks on thinkgs like `thrown new NullReferenceException("myVar")`.
I have the following under Debug=>Exceptions
however, VS breaks on the exceptions. What should I do?
for the application unhandled exception, I "catch" them using the `Application.UnhandledException` as in the the following:
```
''' <summary>Occurs when the application encounters an unhandled exception.</summary> '
Private Sub Application_UnhandledException(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) Handles Me.UnhandledException
Dim message As String = String.Format("An application UnhandledException were thrown.{1}The application will now terminate.{1}'{0}'{1}{1}StackTrace:{1}{2}", e.Exception.Message, Environment.NewLine, e.Exception.StackTrace)
MessageBox.Show(message)
End Sub
```

I have 3 timers running on my application which takes care of different action. Timer 1 will deals with automatic logout of the application, timer 2 deals with updating a table, timer 3 deals with updating the color of swing buttons. First timer uses the calculation based on the variables and its values, second and third timers works out of MYSQL queries.
Now when i run this application on an average performance machine the application is not moving .I need to wait for few seconds to a normal click to happen or a window to open. Is it something to do with the timers ? If yes do I have any alternative suggestions to get rid of this timer problem?

I have a two-column layout with two 'absolute' positioned divs.
```
#left {
position: absolute;
top: 0;
left: 0;
z-index: 0;
}
#right {
position: absolute;
top: 0;
left: 0
z-index: 0;
}
```
In each column I have images and would like them to be able to overlap one another in differing configurations with z-index. Using wordpress, #left is populated with posts from one category then subsequently, #right is populated.
I have assigned z-index for images in higher than that of , but images in are always on top. I assume it is something to do with the fact that #left appears first in the code?
