4,512,358 | 1 | 4,548,912 | null | 45 | 19,640 | I'm running EclEmma, the Emma plugin for Eclipse, and the coverage report shows only partial coverage for an Enum I've defined, even though it shows the only value in the Enum as being covered. I'm assuming that there is a coverage gap for the implied methods that back the Enum, but I'm not quite sure.
For example, with this Enum, EclEmma highlights everything in green, except for the package declaration:
```
package com.blah;
public enum UserRole {
HAS_ACCESS
}
```
If I pull up the coverage details for the class, I see this:
My question is, what is the best way to get 100% coverage on my Enum classes using EclEmma?

Now I would like to enhance my script by few JavaScript lines and (the links should still work of course). Maybe make them fly up or maybe even explode? Does anybody have an idea here or can share a nice trick?

4,512,401 | 1 | null | null | 1 | 1,677 | Rounded Borders not working in IE .
I've tried to use CSS3 for my GWT web app , and I'm struggling to inject *.htc into my code.
How to reference *.htc file via GWT;
1.I've tried using `ClienBundle` to get it as a resource file.
2.I've referenced its relative path from css file.
Both of the ways couldn't help me.
Is there any way using CSS3 with GWT?
Is anybody using *.htc with GWT or GWT doesn't support CSS3 yet?
I want a div with rounded borders something like that:[demo](http://curved-corner.googlecode.com/files/border-radius-demo.zip)
My project structure is:
```
public class Css3 implements EntryPoint {
interface MyResources extends ClientBundle {
@ClientBundle.Source("myHTCfile.htc")
DataResource htcResource();
}
public void onModuleLoad() {
final MyResources myResources=(MyResources) GWT.create(MyResources.class);
final FlowPanel roundedDiv =new FlowPanel();
roundedDiv.setStyleName("myClass");
roundedDiv.add(new Label("lorem ipsum dolor sit amet lorem dolor" +
"sit amet lorem ipsum dolor sit amet "));
roundedDiv.setSize("200px","200px");
myResources.htcResource().getUrl(); //For what is this necessary?
RootPanel.get().add(roundedDiv);
}
```
}
Css3.css
```
@url myHTCFile htcResource;
.myClass {

So if I go to `http://localhost/hello/`, I want to get `hello` in the `$1`
But if I go to `http://localhost/user/` I want to do nothing in this RewriteRule :) Because other RewriteRule is handling the special pages :)
Instead getting `hello` as `$1` , I get `index.php`, why and how should I fix this?

4,513,030 | 1 | null | null | 10 | 1,066 | I have found that while rendering opaque text in Java (latest version 6u23) uses sub-pixel AA just fine, rendering translucent text does not.
Sub-pixel AA:
 
The same text for which only the color has been changed from 0xFFFFFFFF to 0xBFFFFFFF:
 
As you can see, the translucent text is clearly standard AA and rather than a clean translucent rendering, it has that awful '90s "spidery" appearance.
Is this due to a technical limitation for sub-pixel AA in general, or a bug in Java, or just because Java doesn't even try for translucent text, or have I missed something?

4,513,461 | 1 | 4,513,871 | null | 13 | 3,033 | I know that a servlet container, such as Apache Tomcat, runs in a single instance of the JVM, which means all of its servlets will run in the same process.
I also know that the architecture of the servlet container means each web application exists in its own context, which suggests it is isolated from other web applications.
As depicted here:
Accepting that each web application is isolated, I would expect that you could create 2 copies of an identical web application, change the names and context paths of each (as well as any other relevant configuration), and run them in parallel without one affecting the other. The answers to [this question](https://stackoverflow.com/questions/2050354/running-multiple-versions-of-a-servlet-web-application-parallel) appear to support this view.
However, a colleague disagrees based on their experience of attempting just that.
They took a web application and tried to run 2 separate instances (with different names etc) in the same servlet container and experienced issues with the 2 instances conflicting (I'm unable to elaborate more as I wasn't involved in that work).
Based on this, they argue that since the web applications run in the same process space, they can't be isolated and things such as class attributes would end up being inadvertently shared. [This answer](https://stackoverflow.com/questions/393378/starting-a-threadpool-in-a-servlet-container/393384#393384) appears to suggest the same thing
The two views don't seem to be compatible, so I ask you:
If ,
If ,
and finally, , perhaps scenarios involving resources on the file system, native code, or database connections?

More info:
With the latest comment about HorizontalAlignment, it's clear that SL's implementation of TextTrimming differs from WPF's. In SL, TextTrimming only really works if the text is aligned left. SL isn't smart enough to align the text the way WPF does. For instance:
WPF button:
SL button with the textblock horizontalalignment = left:

4,514,928 | 1 | 5,678,411 | null | 9 | 11,321 | I am trying to have a node (or a subgraph, enclosing a node - whichever is possible/easier) rotated, like shown in this image:
( 'verti-*' )
However, the closest I can to that, is the following `dot` code:
```
digraph graphname {
node [fontname=Monospace, fontsize=14];
subgraph clusterMasterBox {
node [shape=record];
l1 [label = "{ horiz-1 \r| \
horiz-2 \r| \
horiz-3 \r| \
horiz-4 \r} \
"];
subgraph clusterSubRotateBox {
rotate=90;
node [shape=record,rotate=90];
l2 [label = "{ verti-1 \r| \
verti-2 \r| \
verti-3 \r| \
verti-4 \r} \
"];
label="B";
}
label="A"
}
}
```
The only reason I have the `subgraph clusterSubRotateBox` there (and the only reason why it is nested inside the `clusterMasterBox`), is because I hoped I could assign rotation to it, but apparently I cannot - as the above code generates this image:
So my question is - is there a way to rotate a record node; if not on its own, then maybe as a part of subgraph (or a different kind of 'object')?
Thanks in advance for any suggestions,
Cheers!

In versions of Adobe Reader prior to v10 (aka "X"), the PDF loaded without the toolbar displayed—you would just see the PDF document. In the newly-released Reader v10, there is a toolbar that I do not wish to see. I am wondering if anyone knows how to hide this toolbar.
I'm thinking that the answer may lie in the Registry, as there is no direct code that I am using to access Reader. Everything is handled by mime types through the `WebBrowser` control.
My code to load the PDF file is as follows:
```

The CSS term for this type of layout is known as the "holy grail" I think. The problem I am facing is that when I use layouts and solutions I find online I do not get them to work properly as I want them to. What I am trying to do is make a page that, regardless of content, will have the footer at the bottom of the browser and the columns stretching down to it. So far I have only seen pages that have the footer placed where the content stop, the result is some blank space under the footer.

4,515,264 | 1 | null | null | 2 | 6,509 | I've been working on drawing an isometric map with C# / XNA Game Studio, and while I've gotten pretty far it doesn't look quite right and I was wondering if anybody can help.
Here's the code I have for drawing the map:
```
public void Draw(SpriteBatch theBatch, int drawX, int drawY)
{
if ((drawY % 2 == 0))
theBatch.Draw(tileTexture, new Rectangle((drawX * width), (drawY * length / 2), width, length), Color.White);
else
theBatch.Draw(tileTexture, new Rectangle(((drawX * width) + (width / 2)), (drawY * length / 2), width, length), Color.White);
}
```
The code within this method acts as if it were inside a nested for loop, drawing left to right, top to bottom. When the y-value is odd, the row is shifted over to fit, however it looks a bit off.
This is the produced output for an 8x5 map:
As you can see, it doesn't quite look right, and I'm not sure if its an issue with the math in my code, or if it has to do with the order everything is being drawn in. I'm very new to C# and working with sprites, so any help would be greatly appreciated.
Because it might be helpful, here is the other relevant parts of code which draw the map.
The entire Tile Class:
```
public class Tile
{
// Dimension variables
int height;
int width;
int length;
String type;
Texture2D tileTexture;
Vector2 coordinates;
///
/// Tile Constructor
///
public Tile(ContentManager theContent, String theType, Vector2 theCoordinates)
{
width = 68;
length = 46;
type = theType;
coordinates = theCoordinates;
// Sets the right texture to the texture ref
if (theType == "grass")
tileTexture = theContent.Load<Texture2D>(@"Tiles\iso_grass");
}
///
/// Draws the tile at the given location
///
public void Draw(SpriteBatch theBatch, int drawX, int drawY)
{
if ((drawY % 2 == 0))
theBatch.Draw(tileTexture, new Rectangle((drawX * width), (drawY * length / 2), width, length), Color.White);
else
theBatch.Draw(tileTexture, new Rectangle(((drawX * width) + (width / 2)), (drawY * length / 2), width, length), Color.White);
}
}
```
The TileRow class, which holds one row of tiles.
```
public class TileRow
{
public List<Tile> Row = new List<Tile>();
public int rowLength;
public TileRow(int theLength, int yIndex, ContentManager theContent)
{
rowLength = theLength;
Tile thisTile;
// Here the tiles are created and added to the row
for (int x = 0; x < rowLength; x++)
{
thisTile = new Tile(theContent, "grass", new Vector2(x, yIndex));
Row.Add(thisTile);
}
}
///
/// Draw -- invokes the draw method of each tile in the row
///
public void DrawRow(SpriteBatch theBatch, int currentY)
{
for (int x = 0; x < rowLength; x++)
{
Row[x].Draw(theBatch, currentY, x);
}
}
}
}
```
and the MapStruct class, which holds all the rows
```
public class MapStruct
{
public List<TileRow> allRows = new List<TileRow>();
int depth;
// Constructor
public MapStruct(ContentManager theContent, int theDepth, int rowLength)
{
depth = theDepth;
TileRow thisRow;
// Here we make a row of tiles for each level of depth
for (int y = 0; y < depth; y++)
{
thisRow = new TileRow(rowLength, depth, theContent);
allRows.Add(thisRow);
}
}
///
/// Draw - this method invokes the draw method in each tile row, which then draws each tile
///
public void DrawMap(SpriteBatch theBatch)
{
for (int y = 0; y < depth; y++)
{
allRows[y].DrawRow(theBatch, y);
}
}
}
```
Any help on how I could fix this issue, as well as advice on how I could improve my code would be greatly appreciated!

4,515,525 | 1 | 10,733,334 | null | 2 | 4,486 | You don't really need to know here that it is generating Pareto's points; but we never know, maybe someone will say "just use the hidden awesome built-in pareto function!".
## The problem
I have a query returning:
```
resource | activity_percentage
1 | P(1)
2 | P(2)
3 | P(3)
...
N - 1 | P(N - 1)
N | P(N)
```
Where:
- - -
I need to group the resources one by one ({1}, {1; 2}, {1; 2; 3}, ...; {1; 2; ...; N}), accumulating the activity_percentage of the resources present in the group. The final result will be:
```
resource_percentage | activity_percentage
R(1) | A(1)
R(2) | A(2)
...
R(N - 1) | A(N - 1)
```
Where
- -
## My Solution
## 1. Query to get a resource rank and its activity percentage
```
-- Query assigning a number to each resource according to its rank of activity percentage.
SELECT
row_number() OVER (ORDER BY activity_percentage DESC) AS resource,
activity_percentage AS activity_percentage
FROM
Resource_Table
```
We obtain here:
```
resource | activity_percentage
1 | P(1)
2 | P(2)
3 | P(3)
...
N - 1 | P(N - 1)
N | P(N)
```
## 2. Create a serie of number from 1 to N
Is there a SQL feature doing that? For now, I use the same query as above, which is bad and slow...
```
-- Creates a serie from 1 to the number of resources
SELECT
row_number() OVER (ORDER BY activity_percentage DESC) AS i
FROM
Resource_Table
```
We obtain:
```
i
1
2
3
...
N
```
## 3. Add the percentage of resources contained per group
To be able to say, for example, group 1 contains only 1 which represent (100 * 1/N) percent of resources; group N contains every resources; 100 * N / N = 100%
```
SELECT
i, -- i is the number of the group but it actually gives the number of resources it contains too
cast(i AS float) / resources.nb_resources AS resource_percentage
FROM
( -- Creates a number serie from 1 to the number of resources
SELECT
row_number() OVER (ORDER BY activity_percentage DESC) AS i
FROM
Resource
) groups
JOIN
( -- Query only getting the number of resources...
SELECT
count(DISTINCT resource_id) AS nb_resources
FROM
Resource_Table
) customers ON 1 = 1
```
I hate this one since I am doing another query to get the number of resources, which is finally max(i) or the number of lines returned by the query (count(*))...
## 4. Group the resources together
So now, we just have to join these queries with the condition: resource <= i
```
SELECT
groups.i AS group_number,
groups.resource_percentage,
activity_percentage.resource,
activity_percentage.activity_percentage
FROM
(
SELECT
i, -- i is the number of the group but it actually gives the number of resources it contains too
cast(i AS float) / resources.nb_resources AS resource_percentage
FROM
( -- Creates a number serie from 1 to the number of resources
SELECT
row_number() OVER (ORDER BY activity_percentage DESC) AS i
FROM
Resource
) groups
JOIN
( -- Query only getting the number of resources...
SELECT
count(DISTINCT resource_id) AS nb_resources
FROM
Resource_Table
) customers ON 1 = 1
) groups
JOIN
( -- Query assigning a number to every resource according to its activity percentage.
SELECT
row_number() OVER (ORDER BY activity_percentage DESC) AS resource,
activity_percentage AS activity_percentage
FROM
Resource_Table
) activity_percentage ON activity_percentage.resource <= groups.i
```
We obtain:
```
group_number | resource_percentage | resource | activity_percentage
1 | R(1) | 1 | P(1)
2 | R(2) | 1 | P(1)
2 | R(2) | 2 | P(2)
3 | R(3) | 1 | P(1)
3 | R(3) | 2 | P(2)
3 | R(3) | 3 | P(3)
...
N | R(N) | 1 | P(1)
N | R(N) | 2 | P(2)
N | R(N) | ... | ...
N | R(N) | N | P(N)
```
## 5. Simply aggregate per group_number
Changing the above query:
```
SELECT
groups.resource_percentage,
sum(activity_percentage.activity_percentage) AS activity_percentage
FROM
...
GROUP BY
groups.resource_percentage
```
Grouping by the group_number or group_percentage does not matter since each group_number has a corresponding group_percentage.
That's it! We obtain:
```
resource_percentage | activity_percentage
R(1) | A(1) = P(1)
R(2) | A(2) = P(1) + P(2)
...
R(N) | A(N) = P(1) + P(2) + ... + P(N)
```
Graphically:
## Conclusion
I obtain a very long query, mostly due to the creation of groups (my N is 25 550) but I would be very pleased to know a better solution, mostly for steps 2 & 3.
Thanks!!

4,516,139 | 1 | 4,516,720 | null | 4 | 2,322 | I'm trying to map a many-to-many relationship between two entities, but I need to decorate that entity with a number of properties - see the diagram below:
is my relationship table in this case - I added an identity column on it in order to avoid using a composite key, but the valuable information here is really the UserId, the FeedItemId, and the TimeRead attribute. Here is how I have tried to map this relationship, based on similar examples I've seen on StackOverFlow:
```
public class UserMap : ClassMap<User>
{
public UserMap()
{
Id(x => x.UserId).GeneratedBy.Identity();
Map(x => x.UserName).Length(DataConstants.UserNameLength).Unique().Not.Nullable();
Map(x => x.EmailAddress).Length(DataConstants.EmailAddressLength).Unique().Not.Nullable();
Map(x => x.DateJoined).Not.Nullable();
Map(x => x.Password).Length(DataConstants.PasswordHashLength).Not.Nullable();
HasManyToMany(x => x.UserRoles).Cascade.AllDeleteOrphan().AsBag().Table("UsersInRole");
HasManyToMany(x => x.SubscribedFeeds).Cascade.DeleteOrphan().AsBag().Table("Subscriptions");
HasManyToMany(x => x.OwnedFeeds).Cascade.All().AsBag().Table("FeedOwners");
HasMany(x => x.Reads).Cascade.DeleteOrphan().Fetch.Join().Inverse().KeyColumn("UserId");
}
}
```
```
public class FeedItemMap : ClassMap<FeedItem>
{
public FeedItemMap()
{
Id(x => x.FeedItemId).GeneratedBy.Identity();
Map(x => x.OriginalUri).Not.Nullable().Unique().Length(DataConstants.FeedUriLength);
Map(x => x.DatePublished).Not.Nullable();
Map(x => x.Title).Not.Nullable().Length(DataConstants.FeedItemTitleLength);
References(x => x.Feed);
HasManyToMany(x => x.Tags).Cascade.All().Table("PostTags");
HasManyToMany(x => x.Categories).Cascade.All().Table("PostsInCategory");
HasMany(x => x.Reads).Cascade.AllDeleteOrphan().Inverse().Fetch.Join().KeyColumn("FeedItemId");
}
}
```
:
```
public class FeedReadMap : ClassMap<FeedRead>
{
public FeedReadMap()
{
Table("Reads");
//CompositeId()
// .KeyProperty(x => x.TimeRead, "TimeRead")
// .KeyReference(x => x.ItemRead, "FeedItemId")
// .KeyReference(x => x.Reader, "UserId");
Id(x => x.ReadId).GeneratedBy.Identity();
Map(x => x.TimeRead).Not.Nullable();
References(x => x.Reader).Not.Nullable().Cascade.SaveUpdate().Column("UserId");
References(x => x.ItemRead).Not.Nullable().Cascade.SaveUpdate().Column("FeedItemId");
}
}
```
---
This code doesn't raise errors as-is, but nothing is ever persisted to the Reads table when I try to do the following:
```
var read = new FeedRead {ItemRead = feed.Items[0], Reader = user, TimeRead = DateTime.Now};
user.Reads.Add(read);
feed.Items[0].Reads.Add(read);
_repository.SaveUser(user);
```
This is probably because of the fact that both User and FeedItem have a on the relationship mapping - I did it this way because it's what I saw in most other examples that tried to model this same relationship.
When I remove the .Inverse off of the User mapping, I get this error instead:
> NHibernate.TransientObjectException:
object references an unsaved transient
instance - save the transient instance
before flushing.
My ultimate goal is to be able to do Session.SaveOrUpdate(user) and have it insert any new feed reads directly into the Reads table, but I haven't been able to find a way to do it yet. What am I doing wrong?
I've read through virtually every other question on StackOverFlow about this topic already and haven't found a clear answer to this question.

My question is related to `ServiceASpecificField` and `ServiceBSpecificField`. I feel that these two fields are placed inappropriately because for all records of `service A` for all subscribers in `SubscriberServiceMap` table, `ServiceBSpecificField` will have null value and vice versa.
If I move these two fields in Subscribers table, then I will have another problem. All those subscribers who only avail `service A` will have null value in `Subscribers.ServiceBSpecificField`.
So what should be done ideally?

To illustrate:
ItemID = 1 would be returned because nothing in Params violates Definitions.Min|Max.
ItemsID = 2 would not be returned because Hi = 103 violates Definitions.Max where DefID = 2. Given this, the fact the last entry violates Definitions.Low is inconsequential, but shown for clear illustration.
ItemID = 3 will match because it has a Param that is within range. There is no need to join all Definitions.

4,517,602 | 1 | 4,517,607 | null | 1 | 333 | I have a PHP/PostgreSQL/Oracle-script which displays links as "tags", which can be clicked to display only the database records matching that "tag". And then I have an "X" near every "tag", so that the user can hide uninteresting "tags":
I would like to add a fade out effect to the both elements (the "tag" and the "X") - when the "X" has been clicked. So I am trying:
```

```
However I have 2 problems:
1. When my PHP-script is quick, then I don't see any fade effect at all. (This is a minor problem, because my real script is far from being quick :-) )
2. I only manage to fade out the clicked "X". How can I fade out the "tag" on the left from it? (And I can't use #id here, because my real script has hundreds of such "tags")
Please push the jQuery newbie in correct direction!

4,517,727 | 1 | 4,519,519 | null | 0 | 309 | I'm trying and organizing Official Versions of my solutions and projects within Sharepoint Libraries, and I stumbled across this problem:
There are certain published packages which contain more than one project. I'm currently grouping by a "Project" column I created, but some packages seem to belong in more than one area.
As to say, I want to Split "2011/01 Branch" into 4 website projects. But some packages include more than one website, so I want to see the same file inside every "group".
For instance, I could have a column named Projects with multiple values, so "file_cabbage" would have "Project A", "Project B" and "Project C" as Projects.
So I would have:
Project A:
-
Project B:
- -
Project C:
- -
Project D:
- -
How to accomplish this?
Thanks in advance.

In a new project, the files would look like this:
while all I was able to create was:
Did I mention that the app didn't work anymore this way? It crashed saying the model must not be `nil`. The problem was solved by starting a new project with the same name and dragging the files over to the old one - not the most elegant solution, I suppose.
I figured however that there are things about Core Data that I still don't quite understand, obviously.
Please, enlighten me - what's the magic behind the .xcdatamodeld folder? Why would Foo.xcdatamodel feature that green checked-icon? Does the datamodel need to be compiled or processed in some way?

Wow, I cannot believe it was `u.UserGroupMain.GroupName` thanks .
It was a mockup repo, and I had a unit test to check if the mock repo user had a mock of UserGroupMain but I didn't Assert if the wee property `GroupName` had been set!
Thanks you're suggestion got the code to break in the controller itself. Plus I learnt something new.

But I have now the new problem, that when the "X" link has been clicked and it starts to fade out, then it can still be clicked again and this is bad for my script - because "X" shouldn't completely removes a "tag", but just move it under a hidden section as you can see in this screenshot. And then subsequent click should move it back:
How could I prevent subsequent clicks please?
I probably should call ? But what should be the new value here?

4,519,875 | 1 | 4,523,266 | null | 8 | 4,608 | This is what I want:
1.) When I click my Expander button and it expands it should stretch down to the end of the Grid
see sample image => 
2.) When I write more Text than space is available in the RichTextBox within the Expander ScrollBars must be visible and I should be able to scroll down.
Putting a scrollviewer around the Expander content ain't hard but it does not help even with setting on "Auto" they never appear. Set the scrollviewer on "Visible" I can't scroll because the content of the Expander goes down endlessly.

4,520,058 | 1 | null | null | 2 | 2,106 | I'm learning C on my own and as a exercise i have written a program but it does not work. The program is splitted into 3 parts. A header file, a main file for executing the program a file to define the functions. I'm not using all the functions yet but that shouldn't be the problem.
Here is my header file, nothing special in it.
```
#ifndef EMPLOYEE_H
#define EMPLOYEE_H
struct Employee
{
char first[21];
char last[21];
char title[21];
int salary;
};
struct Employee* createEmployee(char*, char*, char*, int); // Creates a struct Employee object on the heap.
char* getfirstname (struct Employee*);
char* getlastname (struct Employee*);
char* gettitle (struct Employee*);
int getsalary (struct Employee*);
void setfirstname (struct Employee*, char*);
void setlastname (struct Employee*, char*);
void settitle (struct Employee*, char*);
void setsalary (struct Employee*, int);
void printEmployee(struct Employee*);
#endif
```
In this file i define the functions and how they work:
```
#include "7.1.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct Employee* createEmployee(char* first, char* last, char* title, int salary) // Creates a struct Employee object on the heap.
{
struct Employee* p = (struct Employee*) malloc(sizeof(struct Employee));
if (p != NULL)
{
strcpy(p->first, first);
strcpy(p->last, last);
strcpy(p->title, title);
p->salary = salary;
}
return p;
}
char* getfirstname (struct Employee* p)
{
if (p != NULL)
return p ? p->first : "";
}
char* getlastname (struct Employee* p)
{
if (p != NULL)
return p ? p->last : "";
}
char* gettitle (struct Employee* p)
{
if (p != NULL)
return p ? p->title : "";
}
int getsalary (struct Employee* p)
{
if (p != NULL)
return p ? p->salary : 0;
}
void setfirstname (struct Employee* p, char* first)
{
if (p != NULL)
strcpy(p->first, first);
}
void setlastname (struct Employee* p, char* last)
{
if (p != NULL)
strcpy(p->last, last);
}
void settitle (struct Employee* p, char* title)
{
if (p != NULL)
strcpy(p->title, title);
}
void setsalary (struct Employee* p, char* salary)
{
if (p != NULL)
p->salary = salary;
}
void printEmployee(struct Employee* p)
{
if (p != NULL)
{
printf("%s, %s, %s, %d",
p->first,
p->last,
p->salary,
p->salary
);
}
}
```
And the last file is used to executed the program/functions:
```
#include "7.1.h"
#include <stdio.h>
#include <stdlib.h>
int main ()
{
char decision;
struct Employee emp;
struct Employee* emps[3];
for ( int i = 0; i < 1; i ++)
{
printf("Please type in the emplooyes data.\nFirstname:");
scanf("%s", emp.first);
printf("Lastname:");
scanf("%s", emp.last);
printf("Title:");
scanf("%s", emp.title);
printf("Salary:");
scanf("%d", &emp.salary);
emps[i] = createEmployee(emp.first, emp.last, emp.title, emp.salary);
}
printf("Do you want to print out your information? (Y/N):");
scanf("%c", &decision);
if (decision == 'y' || decision == 'Y')
{
printEmployee(emps[1]);
}
}
```

4,520,127 | 1 | 4,520,161 | null | 3 | 906 | I'd like to get some advice on database design. Specifically, consider the following (hypothetical) scenario:
- - -
In this scenario, if an employee leaves the company I also want to make sure I delete them from the `Users` table so that they can no longer access the software. I can achieve this using `ON DELETE CASCADE` as part of the FK relationship between `EmployeeID` in `Employees` and `Users`.
However, I don't want to delete their details from the `UserLog` as I am interested in collating data on how long people spend on the software and the fact that they no longer work at the company does not mean their user behaviour is no longer relevant.
What I am left with is a table `UserLog` that has no relationships with any other tables in my database.
Having looked through books etc / googled online I haven't come across any DB schemas with tables that have no relationships with others and so my gut instinct here is saying that my approach is not robust...
I'd appreciate some guidance please.

My goal is to create two tunnels for both servers and to map the ports to the host machine and make the connection to both database systems accessable. The port mapping should look like:
For tunnel creation I'm using putty on my windows machine: the configuration of putty for connection to the uvm1 looks like:
And the configuration of putty for connection to the uvm2 looks like:
I'm able to connect via ssh to both of the machines. The strage issue is that my tunneling for uvm1 works and for the uvm2 not.
Do anyone know how can I fix this strange issue?!

4,520,941 | 1 | 4,521,690 | null | 20 | 13,151 | We wanted to use a UITabBar in our iPhone app, but with one exception: we have a "sync" button which I wanted to rotate while the sync operation is happening.
Unfortunately this meant having to create a custom tab bar, but that's neither here nor there: the animation I implemented using Core Animation looks awesome. The problem is that while animating, it adversely affects the performance of everything else using animation on the screen: UITableView scrolling, MKMapView panning and pin drops, etc. My test device is an iPhone 4.
The problem seems to be how I've implemented the tab bar - I wanted to achieve something very similar to UITabBar, where you just supply a PNG for the icon and it uses the alpha channel to create the normal and highlighted states by masking a background image. I accomplished this with CALayer's `mask` property:
```
// Inside a UIView subclass' init method...
// Create the mask layer by settings its contents as our PNG icon.
CALayer *maskLayer = [CALayer layer];
maskLayer.frame = CGRectMake(0, 0, 31, 31);
maskLayer.contentsGravity = kCAGravityCenter;
maskLayer.contentsScale = [[UIScreen mainScreen] scale];
maskLayer.rasterizationScale = [[UIScreen mainScreen] scale];
maskLayer.contents = (id)symbolImage.CGImage;
maskLayer.shouldRasterize = YES;
maskLayer.opaque = YES;
fgLayer = [[CALayer layer] retain];
fgLayer.frame = self.layer.frame;
fgLayer.backgroundColor = [UIColor colorWithImageNamed:@"tabbar-normal-bg.png"].CGColor;
fgLayer.mask = maskLayer; // Apply the mask
fgLayer.shouldRasterize = YES;
fgLayer.opaque = YES;
[self.layer addSublayer:fgLayer];
```
(Note: in the screenshot above you can see I've also added a shadow layer, but for simplicity I removed that from the code. I remove the shadow layer from the sync icon when it is animating, so it shouldn't be relevant.)
To animate, I simply rotate the mask layer:
```
- (void)startAnimating {
CABasicAnimation* animation = [CABasicAnimation animationWithKeyPath: @"transform"];
CATransform3D transform = CATransform3DMakeRotation(RADIANS(179.9), 0.0, 0.0, 1.0);
animation.toValue = [NSValue valueWithCATransform3D:transform];
animation.duration = 5;
animation.repeatCount = 10000;
animation.removedOnCompletion = YES;
[fgLayer.mask addAnimation:animation forKey:@"rotate"]; // Add animation to the mask
}
```
So this all works great except for performance. You can see I've already tried tips that turned up on Google about rasterizing layers / making them opaque - hasn't helped.
I think I've identified the mask layer as being the culprit. When I take out the mask layer and just rotate the `fgLayer` instead of its mask, performance is wonderful, though it's certainly not the affect I'm going for:
Performance is also just as bad as before if I rotate the `fgLayer` instead of the mask the mask is applied.
So if having to recomposite the mask each frame of the animation is the slow down, are there any other techniques I can use to achieve a similar affect that will have better performance? Using a path instead of an image for the mask layer? Or am I going to have to drop down to OpenGL or something to get good performance?
further reinforcing the idea that the mask is the slowdown, my coworker suggested trying to rotate a CALayer with just the image as the contents -- so similar to my example above w/o a mask -- and performance was also good that way. So I can really only do a solid color like that (no gradient), but it may be a good interim solution. I'd still love to achieve rotating a mask with good performance though, so suggestions welcome :)

4,521,973 | 1 | 4,586,307 | null | 16 | 34,896 | I'm trying to add an external icon from an *.ico file to a window that I'm creating using the WindowBuilder design window.
I can select the shell, which brings up an "image" properties field.
That brings up the image chooser dialog box:
How do I make my icon show up in this menu as a classpath resource? The image works if an absolute path is given, but I don't want to use that option in my application.
Thanks!

4,522,108 | 1 | 4,578,563 | null | 4 | 514 | On the Motorola Bravo, at the left bottom of a MapView, there is an ugly orange square rather than the google logo. I notice this not only on my app, but on say, Yelp -- see screen shot:
Has anyone else seen this, and is there a workaround? I don't know if it happens on other motorola phones, but I'm guessing it does because there is another, similar problem with a missing image on google maps, which is easy enough to solve and [documented elsewhere](http://dimitar.me/applications-that-use-the-mylocationoverlay-class-crash-on-the-new-droid-x/) as being on Droid phones as well.

4,522,325 | 1 | 4,522,359 | null | 4 | 3,328 | I installed iOS 4.2 on my 2nd-generation iPod Touch last week. I tried running my application on the device through Xcode, but it didn't work (because Xcode didn't yet support iOS 4). To solve that, I installed Xcode 3.2.5 and the iOS SDK 4.2. Now I can get the app to run in the iPhone/iPad Simulator just fine.
However, I can no longer select "Device" from the menu at the top of the screen. It's a choice, but when I try to click on it, it never actually gets a check mark.
Because of this, I can no longer run the app on my iPod. The other (related) problem is that I can't choose "Build and Archive" from the Build menu anymore because the target is not a device.
Why is this happening? Do I need to change some settings in my project, or something with my device itself?
Upon closer investigation, it appears that I can't select anything but the iPhone Simulator 4.0. Maybe there's something wrong with the project file.

The deletes/adds occur in a `foreach` scope and there is a `SaveChanges()` outside the `foreach`.
In the above image you see that each takes 6 seconds, which is 34% of the time, for 16 calls.
That doesn't sound normal to me...

4,522,770 | 1 | null | null | 4 | 4,179 | CTEs are a bit new to me so I am hoping someone can help with the following one which I wrote that will take a category table and build a hierarchy out of it for display. I know this kind of thing is asked all the time, but I think my situation with the sorting makes it a bit unique.
I would expect a number of suggestions to use HierarchyID, but sadly that is not an option for a long list of reasons that are not relevant here. The solution I have come up with though works and gives me the data I expect, but I am wondering if there is a better/more elegant way of accomplishing this.
The basic requirements are as follows:
1. Categories can have an unlimited number of children
2. Categories can be an unlimited number of levels deep
3. Categories with the same parent will be sorted based on a "sort" field. If one is not specified (default is 0) or is the same as another sibling category, it will sorted alphabetically.
Table Definition:
```
CREATE TABLE [dbo].[TreeTest]
(
[id] [int] NOT NULL,
[parent] [int] NULL,
[title] [varchar](50) NOT NULL,
[sort] [int] NOT NULL
)
GO
ALTER TABLE [dbo].[TreeTest] ADD CONSTRAINT [DF_TreeTest_sort] DEFAULT ((0)) FOR [sort]
GO
```
Insert statements:
```
INSERT TreeTest(id,parent,title,sort) VALUES('1',NULL,'Parent 1','0')
INSERT TreeTest(id,parent,title,sort) VALUES('2',NULL,'Parent 2','0')
INSERT TreeTest(id,parent,title,sort) VALUES('3',NULL,'Parent 3','2')
INSERT TreeTest(id,parent,title,sort) VALUES('4',NULL,'Parent 4','1')
INSERT TreeTest(id,parent,title,sort) VALUES('5','1','Child 1a','0')
INSERT TreeTest(id,parent,title,sort) VALUES('6','2','Child 2a','0')
INSERT TreeTest(id,parent,title,sort) VALUES('7','3','Child 3a','0')
INSERT TreeTest(id,parent,title,sort) VALUES('8','1','Child 1b','1')
INSERT TreeTest(id,parent,title,sort) VALUES('9','1','Child 1c','2')
INSERT TreeTest(id,parent,title,sort) VALUES('10','1','Child 1d','1')
INSERT TreeTest(id,parent,title,sort) VALUES('11','6','Child 2a 1','0')
INSERT TreeTest(id,parent,title,sort) VALUES('12','6','Child 2a 2','1')
INSERT TreeTest(id,parent,title,sort) VALUES('13','6','Child 2a 3','0')
INSERT TreeTest(id,parent,title,sort) VALUES('14','6','Child 2a 4','2')
```
CTE:
```
WITH TreeList (id, parent, title, sort, title_path, level_id, level_id_path) as
(
SELECT p.id,
p.parent,
p.title,
p.sort,
CONVERT(nvarchar(max), p.title),
ROW_NUMBER() OVER(PARTITION BY parent ORDER BY p.sort, p.title),
CAST(ROW_NUMBER() OVER(PARTITION BY parent ORDER BY p.sort) AS varchar(max))
FROM TreeTest p
WHERE p.parent is null
UNION ALL
SELECT c.id,
c.parent,
c.title,
c.sort,
r.title_path + '/' + c.title,
ROW_NUMBER() OVER(PARTITION BY c.parent ORDER BY c.sort, c.title),
CONVERT(varchar(max), r.level_id_path + '.' + CAST(ROW_NUMBER() OVER(PARTITION BY c.parent ORDER BY c.sort, c.title) AS VARCHAR))
FROM TreeTest AS c
INNER JOIN treelist AS r
ON c.parent = r.id
)
SELECT *
FROM TreeList
ORDER BY level_id_path
```
Output (I figured an image was the easiest way to show the output)
Again, this works according to the specifications I have, but I'm not sure about the efficiency and whether or not there is a better way to do this. When I look at the execution plan for this, it seems like the most expensive piece is the sorting/index scanning, but this seems expected given the lack of indexes in this example. If anyone has any input it would be greatly appreciated.

But as I added complexity I suddenly started getting this error whenever I open generic.xaml in Blend and so far I've been unable to find the culprit...
Strangely, the project still builds and the styles work as expected. So I can in fact make design changes by changing generic.xaml and rebuilding. But I'd hope to fix this problem so I can make modifications within Blend more easily. Any ideas?

See the image groups A and B.
You can easily find the difference.
Group A has a smoother RED line whereas Group B has RED line but it is not smoother.
My problem is, I want to make red line smoother in Group B.
Which algorithm will help me?
Or suggest me best algorithm for make that line smoother

4,524,322 | 1 | 4,534,974 | null | 1 | 1,803 | I have a problem with a list view and a custom cursor adapter and I just can't seem to figure out what is wrong with my code. Basically, in my activity I call initalize() that does a bunch of stuff to handle getting the proper data and initializing the listview. On first run of the activity you can see from the images that one of the items is missing from the list. If I go to another activity and go back to this activity the item that was missing shows up. I believe it has something to do with setContentView(R.layout.parent). If I move that to my initialize() then the item never shows up even when returning from another activity. So, for some reason, returning from another activity bypasses setContentView(R.layout.parent) and everything works fine. I know it's impossible for me to bypass setContentView(R.layout.parent) so I need to figure out what the problem is. Also, I did not include the layout because it is nothing more then two textviews.
Also, the images I have attached do not show that the missing item is the last one on the list.
Custom Cursor Adapter:
```
public class CustomCursorAdapter extends SimpleCursorAdapter {
private Context context;
private int layout;
public CustomCursorAdapter (Context context, int layout,
Cursor c, String[] from, int[] to) {
super(context, layout, c, from, to);

4,525,115 | 1 | null | null | 0 | 900 | ok so Im new to mvc. What Im making is a -create user form-. The UserViewModel has a branchcode property of type `long`. I want a small branch selector, where instead of a plain textbox for the code I have a textbox and a link, when clicked would return the name of the branch with some ajax.
So I made a branch selector and put it under Shared/EditorTemplates. Looks like this
```
@model long
<div class="editor-label">
Branch ID: @Html.TextBoxFor(model => model)
@Ajax.ActionLink("Get Branch Name", MVC.Admin.Home.BranchDetail(Model),
new AjaxOptions { UpdateTargetId = "BranchName", LoadingElementId = "loading" })
<p id="loading" style="display: none">
Loading...
</p>
</div>
<div id="BranchName" class="editor-field">
</div>
```
I have the UIHint setup in the viewmodel so when I say EditFor(model.BranchName) it shows up perfectly like this:
My problems:
There is When I click it goes the the url : [http://localhost:1159/Admin/Home/BranchDetail?brcd=0](http://localhost:1159/Admin/Home/BranchDetail?brcd=0) And then the URL throws an error because there is no BranchDetailsView anywhere.
This is what the controller looks like:
```
public virtual ActionResult BranchDetail(long brcd)
{
if (Request.IsAjaxRequest())
{
//code to find branch
if (br == null)
{
return Content("No Branch Found");
}
else
{
return Content(br.BranchName + "Circle: " + br.Circle);
}
}
return View();//we should not be here.
}
```
Another problem is, how do I get the AjaxLink to return what code what typed. If you notice the screenie, the url to the link has `brcd=0`. I want to send over the branch code to the controller! I tried `BeginRouteForm` with an input button inside the editor, but that ends up submitting the entire Create page form? Would that be the right way to do this?
Note: Im using T4MVC, also, Initially I forgot but I did reference both `microsoft.ajax.js` and `microsoft.mvc.ajax.js` in the create page.
---
: I managed to get this working with JQuery and it seems pretty nice and simple. However, I would really like to know how this kind of thing would be generally done with `Ajax.BeginForm` since Im learning MVC.

4,526,614 | 1 | null | null | 2 | 2,135 | For some time now I've been trying to remove the blue highlight in UIPickerView when you're using the `pickerView:viewForRow:forComponent:reusingView:` delegate.
I'm sure many here have been there and wanted to remove that ugly blue highlight in the UIPickerView.
The `UIPickerView` has a `UITableView` - rather a `UIPickerTable` inside which has cells where your `UILabels/UIViews/UIImageViews` or whatever lay.
Logically, if it's a tableview, then we can just access the cell and `setSelectionStyle:UITableViewCellSelectionStyleNone` right?
`UIPickerTable` is a private class of the API and does not allow you to set anything in there.
I've managed to get all the subviews in my picker
```
[[myPickerView subviews] objectAtIndex:someIndexValue];
```
So I tried this in `pickerView:didSelectRow:` and `pickerView:viewForRow:`
```
NSIndexPath *path = [[[myPickerView subviews] objectAtIndex:5] indexPathForSelectedRow];
[[[[myPickerView subviews] objectAtIndex:5] cellForRowAtIndexPath:path] setSelectionStyle:UITableViewCellSelectionStyleNone];
```
And this:
```
[[[myPickerView subviews] objectAtIndex:5] setSelectionStyle:UITableViewCellSelectionStyleNone];
```
None of them worked 'cause it's private. Giving me this error:
I know about setting the `view`'s frame to the size of the `pickerView:rowHeightForComponent:` and then doing:
```
label.UserInteractionEnabled = YES;
```
Before returning it on `pickerView:viewForRow` method.
But it doesn't really remove the highlight, it just it and removes the UIPickerView's ability to autoscroll when some item is just clicked.
`UIPickerView``UILabel/UIView/UIImageView`
I'm talking about the selectionIndicator.
This is the highlight that appears when you click an image inside the pickerView: 
PS: This pickerView has NO selectionIndicator and is customized. However, the customization has nothing to do with the issue. This issue is simply for the fact that there's an object that inherits form UIView inside the picker's cell and `viewForRow` is being used.

4,526,852 | 1 | 4,527,045 | null | 7 | 2,022 | I'm implementing an approach from a research paper. Part of the approach calls for a major edge detector, which the authors describe as follows:
1. Obtain DC image (effectively downsample by 8 for both width and height)
2. Calculate Sobel gradient of DC image
3. Threshold Sobel gradient image (using T=120)
4. Morphological operations to clean up edge image
Note that this Canny edge detection -- they don't bother with things like non-maximum suppression, etc. I could of course do this with Canny edge detection, but I want to implement things exactly as they are expressed in the paper.
That last step is the one I'm a bit stuck on.
Here is exactly what the authors say about it:
> After obtaining the binary
edge map from the edge detection process, a binary morphological
operation is employed to remove isolated edge pixels,
which might cause false alarms during the edge detection
Here's how things are supposed to look like at the end of it all (edge blocks have been filled in black):
Here's what I have if I skip the last step:
It seems to be on the right track. So here's what happens if I do erosion for step 4:
I've tried combinations of erosion and dilation to obtain the same result as they do, but don't get anywhere close. Can anyone suggest a combination of morphological operators that will get me the desired result?

Now I want to control my computer with TV remote, but I don't have any clue how to compare audio input with pre-recorded audio. But after I realized that these audio waves contains only some kind data (binary) I can turn these into binary or hex, so it is much easier to compare.
Waves look just like this:
And this:
These are records of "OK" button, sometimes there are some impulses on right channel too and I don't know why, it seems like connections in sensor are damaged maybe.
Ok thats not matter, anyway
I know it's sounds like "Do it for me, while I enjoy my life", but I don't have experiences with sound transforming/reading... I've looking for python examples for recording and reading audio, but unsuccessfully.

The particular problem I'm trying to fix involves working with image files stored on a local drive, and manipulating the file names which may contain foreign characters. The two experiments shown below are intermediate debugging steps.
The `ã` character is common in latin languages. e.g. [](http://pt.wikipedia.org/wiki/C%C3%A3o)[http://pt.wikipedia.org/wiki/Cão](http://pt.wikipedia.org/wiki/C%C3%A3o)
Look closely, note how `cão` becomes `cao`.
Here I tried using File::Find instead of piped input, in case the issue was with the Windows implementation of the `|` shell operator. The issue actually gets worse, as the `~a` becomes `Pi`:

Debugging update:
I tried some of the tricks listed at [http://perldoc.perl.org/perlunicode.html](http://perldoc.perl.org/perlunicode.html),
e.g. `use utf8`, `use feature 'unicode_strings'`, etc, to no avail.

# Intro
Here is an example to illustrate the problem. Consider I am tracking and displaying mouse global current position and last click button and position to the user. Here is an image:
To archive capturing click events on windows box, that would and will be sent to the other programs event messaging queue, I create a hook using winapi namely `user32.dll` library. This is outside JDK sandbox, so I use JNA to call the native library.
This all works perfectly, but it does not close as I expect it to.
My question is - How do I properly close following example program?

Code below is not fully written by Me, but taken from [this](http://forums.oracle.com/forums/thread.jspa?threadID=1546451) question in Oracle forum and partly fixed.

I check my database I see that property is ResCom insert
but when I check the value of role I get null
```
Utilisateur tets= gr.findByEmail(email);
message=tets.getEmail()+" and Role :"+tets.getRole()+"";

but in my bass it ResCom !!!!!
the problem disappears when I deploy the project again
I hope you have a solution

4,528,399 | 1 | 4,528,673 | null | 8 | 4,333 | I have a html table with a column of text boxes (), all of them are disabled when the page loads, and I need that when user clicks on a check box, the text box for that column should be enabled and become a required field, and then if the user unchecks the checkbox, the textbox on that row must be disabled and the required class removed.
I already have the function to enable and disable the text boxes (column ) when the user clicks on the corresponding checkbox, but it is written in javascript.However, for some reason it only works in IE).
Here is the html code
```
<tbody>
<c:forEach items="${list}" var="item">
<tr>
<td align="center">
<input type="checkbox" name="selectItems" value="<c:out value="${item.numberPlate}"/>" onchange="enableTextField(this)" />
</td>
<td align="left"><c:out value="${item.numberPlate}"/></td>
<td align="left"><c:out value="${item.driver.fullName}"/></td>
<td align="left"><input type="text" name="mileage_<c:out value="${item.numberPlate}"/>" value="" disabled="true"/></td>
</tr>
</c:forEach>
</tbody>
```
And the javascript code:
```
function enableTextField(r)
{ var node = r.parentNode;
while( node && node.tagName !== 'TR' ) {
node = node.parentNode;
}
var i=node.rowIndex;
if(document.form1.selectItems[i-1].checked)
{
document.getElementById('mileage_' + document.form1.selectItems[i-1].value).disabled=false;
}
else
{
document.getElementById('mileage_' + document.form1.selectItems[i-1].value).value="";
document.getElementById('mileage_' + document.form1.selectItems[i-1].value).disabled=true;
}
}
```
Now, I know that in order to add or remove dynamically validation rules I have to use: addClass('required'); o removeClass('required') ,but I don't know how to detect whether a check box is selected or not, and based on that ,enable or disable the text box for that row.
I really hope you can help me out with this.
