5,018,229 | 1 | 5,019,869 | null | 0 | 238 | I'm creating a method that populates some textboxes with data retrieved from an Access database using table adapters.
The `GetCasesWithUserFromCaseId` method return a single case with the `username` which is found by left joining my cases table with my users table.
For some reason I get a NullReferenceException when trying to access the joined data (userdata) from the users table but data from the cases table works. I'm sure that all fields is set for all users and all cases-tablerows.
If this doesn't work how do I then alternately get my data? I've attached an image showing my simple database.
The sql-statement:
```
SELECT *
FROM cases
LEFT JOIN users ON cases.caseCreatedBy = users.userId
WHERE caseId = caseNum
```
The C# code:
```
public void populateBoxes(int caseId)
{
caseDBTableAdapters.casesTableAdapter casesAdapter =
new caseDBTableAdapters.casesTableAdapter();
caseDB.casesDataTable cases;
cases = casesAdapter.GetCasesWithUserFromCaseId(caseId);
foreach (caseDB.casesRow casesRow in cases)
{
tbCaseName.Text = casesRow.caseName;
tbOwner.Text = casesRow.usersRow.firstName.ToString();
}
}

5,018,236 | 1 | 5,115,470 | null | 6 | 2,740 | I have a problem with Pocos and nullable foreign keys .
I have 2 tables (orders and products) each table have a composite primary key (orderid,orderid2) and (productid,productid2)
And I have set a 0,1..* association between the two tables.
One order can be related to 0 or 1 product.
And one product has * orders related to him.

5,018,635 | 1 | 5,019,257 | null | 9 | 1,816 | I've never worked with Java drawing methods before, so I decided to dive in and create an analog clock as a PoC. In addition to the hands, I draw a clock face that includes tick marks for minutes/hours. I use simple sin/cos calculations to determine the position of the lines around the circle.
However, I've noticed that since the minute tick-marks are very short, the angle of the lines looks wrong. I'm certain this is because both `Graphics2D.drawLine()` and `Line2D.double()` methods cannot draw with subpixel accuracy.
I know I can draw lines originating from the center and masking it out with a circle (to create longer, more accurate lines), but that seems like such an inelegant and costly solution. I've done some research on how to do this, but the best answer I've come across is to use an `AffineTransform`. I assume I could use an `AffineTransform` with rotation only, as opposed to having to perform a supersampling.
Is this the only/best method of drawing with sub-pixel accuracy? Or is there a potentially faster solution?
`RenderingHint``Graphics2D`
As requested, here is a little bit of the code (not fully optimized as this was just a PoC):
```
diameter = Math.max(Math.min(pnlOuter.getSize().getWidth(),
pnlOuter.getSize().getHeight()) - 2, MIN_DIAMETER);
for (double radTick = 0d; radTick < 360d; radTick += 6d) {
g2d.draw(new Line2D.Double(
(diameter / 2) + (Math.cos(Math.toRadians(radTick))) * diameter / 2.1d,
(diameter / 2) + (Math.sin(Math.toRadians(radTick))) * diameter / 2.1d,
(diameter / 2) + (Math.cos(Math.toRadians(radTick))) * diameter / 2.05d,
(diameter / 2) + (Math.sin(Math.toRadians(radTick))) * diameter / 2.05d));
} // End for(radTick)
```
Here's a screenshot of the drawing. It may be somewhat difficult to see, but look at the tick mark for 59 minutes. It is perfectly vertical.

5,018,713 | 1 | 5,018,841 | null | 0 | 48 | So I've been googling around, but just havn't found any good solution for this layout yet.
What Im trying to do is like a gallery. First thumbs, then a large below the clicked thumb.
The problem is to separate different events.
>
1. A click with no visible div. (Slide down selected div)
2. A click with a visible div. (Transition to new div. Hide old, then show the new one or something)
3. A click with an already selected div. (Slide up selected div)
Been struggling around with different solutions, but either it's glitchy or sometimes it doesn't react to clicks at first.
Basic structure so far:
```
<ul>
<li id="case1">Thumb1</li>
<li id="case2">Thumb2</li>
<li id="case3">Thumb3</li>
</ul>
<div id="case1box">Content</div>
<div id="case2box">Content</div>
<div id="case3box">Content</div>
```
Then repeating that snippet. Any better solution, as it's UL(3xLI) then DIV, UL(3xLI) then DIV?

I get the message and the loading indicator keeps spinning. This stays like this for about 10 seconds and then Chrome gives up and tells me from within the developer console. The image is definitely at the path stated. Sometimes it loads sometimes it doesn't. If I remove reference to this image altogether the error will fall on a different image within the page. This is a regular but intermittent fault.
My site is javascript heavy (2500+ lines) I suspect it could be something to do with either:
1. Javascript loading interfering with image loads.
2. Something funny going on regarding the caching of images.
Does anyone have any experience of this type of page load problem?
Appreciate any help you can give!

The file that fails can vary from CSS background-image to normal image to even a font file. I think this problem is deeper than client side.

We have stripped the page of ALL javascript, it's almost a bare shell! The image load problems continue to occur cross browser.
I have found that the following errors in http error log seem to be linked with the problem. Anyone know what they mean and how to solve them?

I am new to WatiN, but not new to writing automated Web UI tests. At my new job, we are trying to use WatiN for our Web UI tests (thanks to a few CUIT fails).
I've solved this problem in the past using ArtOfTest.WebAii, by using a Win32 mouse click with a magic number offset from the containing element, but I can't seem to find documentation on how to do that in WatiN and I can't figure it out myself :\
This dialog appears and I can't seem to find a way for WatiN to click it.
The dialog has the following markup:
```
<OBJECT style="FILTER: alpha(opacity=1); WIDTH: 329px; HEIGHT: 100px; mozOpacity: 0.01; opacity: 0.01; mozopacity: 0.01" data="data:application/x-oleobject;base64, <a bunch of data>" width=329 height=100 type=application/x-silverlight-2></OBJECT>
<param name="source" value="/CuteWebUI_Uploader_Resource.axd?type=file&file=silverlight.xap&_ver=634334311861475176"/>
<param name="windowless" value="true" object="" <=""/>
```
my test code:
```
[TestMethod]
public void SomeTest()
{
Settings.MakeNewIeInstanceVisible = true;
Settings.AutoStartDialogWatcher = true;
Settings.AutoMoveMousePointerToTopLeft = false;
using (IE ie2 = new IE())
{
ie2.GoTo(URL);
ie2.Link(SomeButtonID).Click();
ie2.Image(AnotherButtonID).FireEvent("onclick");
// some debugging code wrapped around the next user action
// which is clicking on the attach file button
var helper = new DialogHandlerHelper();
using (new UseDialogOnce(ie2.DialogWatcher, helper))
{
Thread.Sleep(1 * 1000); // wait for attach button to be "ready"
// Click button that triggers the dialog that states:
// "file browsing dialog has been blocked"
// "please click here and try again"
//
ie2.Button(FileAttachButtonID).FireEvent("onclick");
}
foreach(string dialogHandler in helper.CandidateDialogHandlers)
{
// nothing prints out here :(
Console.Out.WriteLine(dialogHandler);
}
// debug print out all elements with tagname = object
foreach (Element objectElement in ie2.ElementsWithTag("object"))
{
StringBuilder elementInfo = new StringBuilder();
elementInfo.AppendLine("--------------------------------------------");
elementInfo.AppendLine("element.tagname = " + objectElement.TagName);
elementInfo.AppendLine("element.style = " + objectElement.Style);
elementInfo.AppendLine("element.type = " + objectElement.GetAttributeValue("type"));
elementInfo.AppendLine("element.data = " + objectElement.GetAttributeValue("data"));
elementInfo.AppendLine("--------------------------------------------");
Console.Out.WriteLine(elementInfo.ToString());
// none of these clicks make the dialog go away
objectElement.ClickNoWait();
objectElement.Click();
objectElement.DoubleClick();
objectElement.MouseEnter();
objectElement.MouseDown();
Thread.Sleep(500);
objectElement.MouseUp();
}
// wait to see if dialog disappears after click
Thread.Sleep(300 * 1000);
}
}
```
Any and all help will be very much appreciated.
Thanks!

Domain Driven Design can be really confusing at times and since I am rather new to this technique I would like to have some answers regarding those scenarios that are currently bugging me.
Here a simple diagram to represent my question using DDD principles. My question is about aggregate roots, domain validation and "ways to do" or best practices.
1. In this scenario, how would you implement a way to count the number of comments written by a user? Would it be a method in "Review"? Or would it be best to be a method in a repository (ReviewRepository)?
2. How do I make other entities access comments if they need to? Having this scenario, does that mean that Comment isn't part anymore of the "Review" aggregates?
3. What if comment have a composition relationship with some other entity? How would you manage the access to that entity? Is comment responsible of this entity or the root?
4. Any other suggestions or facts regarding this model? Any best practices I should fellow when designing a model?
Thanks.
There a little error in the Review entity. "Compte" in the Add method is "Account" and should be A instead of C.

5,022,613 | 1 | 5,024,045 | null | 4 | 1,758 | I am working with a WPF application that uses alot of drag and drop. Everything is working fine, with exception of ListBoxItems. I have a ListBox with ListBoxItems that can be dragged to another target( a StackPanel). The problem is, when I drag the cursor outside the ListBox, I cant see the Adorner that I have setup with the ListBoxItem?
I know this is a common problem, but I am just not sure how to fix it. Is there something that I need to do to allow me to drag outside of the ListBox control?
Below I have attached what the UI looks like so far. As you can see, there is a ListBox on the bottom left. When I drag an item, the adorner appears, and follows the cursor around while the cursor is over the ListBox, but if I try to move the cursor away from the listbox, the Adorner seems to almost go under the other controls(zIndex?).
I have changed the code to handle the AdornerLayer relative to the window as oppose to relative to the AdornedElement
So I changed
```
layer = AdornerLayer.GetAdornerLayer(_originalElement);
```
to
```
layer = AdornerLayer.GetAdornerLayer(this);
```
This solved the problem of the ScrollViwer clipping the AdornerLayer

5,023,365 | 1 | 5,033,812 | null | 1 | 2,445 | In my application, I have to write a query that displays data from a number of the tables. In other words, I have to create a query that will make a join for number of tables and will show wanted information from this query.
The query has to display all the events (and all data about the events in `DataGrid`) for a specific (chosen) worker.
Here is a code of my LINQ:
```
IList dataList = (from dWorker in App.glidusContext.tbl_workers
where dWorker.workerTZ == strSplit
join d2 in App.glidusContext.tbl_workers_has_tbl_events
on dWorker.workerID equals d2.workerID
join dEvent in App.glidusContext.tbl_events
on d2.eventID equals dEvent.eventID
join dAct in App.glidusContext.tbl_activities
on d2.eventID equals dAct.eventID
select new { d2.damagedVacantionEnd, dEvent, dAct }).ToList();
return dataList;
```
Where `strSplit` is a specific (chosen) worker.
XAML-code of `DataGrid`:
```
<DataGrid.Columns>
<DataGridTextColumn Header="{x:Static res:Resources.WinSafetyByEmployee_DataGrid_ColHead_Event_type}"
Width="130"
IsReadOnly="True"

```
How to fix this query? Now this variant doesn't return values.
I also cannot reach tbl_objects in the query because I need to do it thought the connection table `tbl_object_has_tbl_events` and `App.glidus` do not show such a table.

5,023,535 | 1 | 5,023,842 | null | 0 | 935 | I am in the process of developing a universal iOS app.
What I want is for all my views to automatically resize depending on the screen sisze, I mean I dont want to hard code any `CGRect` sizes or use Interface Builder; I am using a specific app example but I would very much appreciate an answer that is usable in many similar scenarios.
This is a very simple app but I hope the answer can show me how to go about doing this for all my views, so they can adjust to any size.
For this specific app I am building something that will look like this:
This is a particularly tricky example as the MKMapView has to be initialized with a frame but I hope you can help me.
The first problem I ran into was the fact that in my loadView method:
```
MKMapView *mapView=[[MKMapView alloc ] initWithFrame:CGRectZero];
mapView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
self.view=mapView;
```
The autoresizing mask does not work unless the view controller is managed by a `UINavigationController`; I do not know why.
The next problem comes when I want to add my UIToolbar at the bottom of the screen.
In order to get this I do the following:
```
UIToolbar *toolBar=[[UIToolbar alloc] initWithFrame:CGRectMake(0, 420, 320, 40)];
toolBar.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[self.view addSubview:toolBar];
```
This works perfectly with an iPhone but it does not with an iPad (the toolbar's width is adjusted but it obviously is no loger at the bottom of the screen) as the size is hard coded.
Sorry for posting such a long question but I think the answers can be a great resource for me and other developers in need.
Please tell me If I am not clear.

5,023,702 | 1 | 5,023,945 | null | 1 | 351 | I am in desperate need of either algorithm or query construction assistance.
We have a user-generated, flexible database that is created using a form builder we have created. The data for these forms is stored in two tables as follows:
The instances table tell us what form the user is viewing, and then the instance_records table has all the data for the instance. The field_id column tells us what field on the form the data maps to. The reason we use a single table like this instead of creating a table for each form is that MySQL limits how many columns we can have in table given that the data is varchar of a significant length. One possibility would be to use Text fields for the data, but then we would lose the built in MySQL searching capabilities.
Things work quite well and very fast on basic forms. The problem is that one instance of a form can refer to another instance of the form. For example, we have user created form called Appointments. On this form, it refers to the Patient form, the Technician form, the Doctor form, etc.
So, on the Appointment form with instance id, the value for the patient field is actually an instance id of a patient, the doctor field value is the instance id for the doctor, etc. At the first level of references, things aren’t too bad. But, you can have chains of references. I can have a prescription that refers to an appointment that refers to a patient, etc. So, if I want to get the value of the patient name on the prescription, I have to follow the chain down to get the right instance id and field id for the data.
So, if I want to do a report on Appointments and show the Patient name, the Doctor name, and the Technician name, I have to go through some hoops. What I have tried is creating views and then joining the views to a final view that shows all the data for the query. But, it eats a ton of memory and starts writing the view temporary tables to disk and gets slow as all heck. Using query caching, the second time the report runs, it’s fast as heck. But, that first run can take over a minute once we get above 5000-7000 instances.
Something tickling at the back of my mind is that there might be some sort of a way to store the data in a way that I can take advantage of some faster tree search algorithms.

The first part is pretty easy with:
```

The second part is difficult because absolutely positioned elements are outside of the content-flow and won't trigger scrolling.

5,024,191 | 1 | 5,045,270 | null | 2 | 8,162 | I'm working on a web design that has a fixed sidebar and breadcrumb header, and a scrollable content section taking up the remaining space. Here's what I envision the end result looking like:
The rub is, I can't figure out how to make this work without nasty container `<div>`s or hacky CSS. I like semantic HTML (HTML 5, for this specific project) so I don't really want to budge on keeping styling elements out of the markup.
The sidebar will have two fixed widths (expanded and collapsed) and the header will always have a fixed height.
This is (essentially) how I'd like the markup to look:
```
<body>
<aside>
<!-- sidebar content -->
<h1>My Site</h1>
</aside>
<section>
<nav>
<!-- breadcrumbs -->
<a href="#home">Home</a>
<a href="#area">Area</a>
<a href="#category">Category</a>
<a href="#">Item</a>
</nav>
<article>
<!-- page content -->
<h2>Item Title</h2>
<p>
Item Content
</p>
</article>
</section>
</body>
```
Can someone help me make the CSS work for this?
My CSS thus far:
```
html {
font-family: "Segoe UI", sans-serif;
font-size: 9pt;
height: 100%;
}
html body {
margin: 0px;
height: 100%;

As you can see, basically what happens is when it writes a string called "resolved" it knows that the very next column, which is the title column, gets a strikethrough. It works just fine, but for whatever reason, the strikethrough is not drawing over the entirety of the text!

5,024,479 | 1 | null | null | 0 | 1,620 | I have written a c++ wrapper dll for a C dll with lib file I have, now everything is partially working, all the functions I have written in the c++ wrapper class work as expected bar one.
Here it is in the C++ dll
```
__declspec(dllexport) long ReadRawDataByTime(char * tagname, long serverhandle, IHU_TIMESTAMP * StartTime, IHU_TIMESTAMP * EndTime, int * number_of_samples, IHU_DATA_SAMPLE **data_values){
return ihuReadRawDataByTime(serverhandle, tagname, StartTime, EndTime, number_of_samples, data_values);
}
```
and here is my definition and how I call it in C#
```
[DllImport("IHUAPIWrapper.dll")]
public static extern long ReadRawDataByTime(String tagname, long serverhandle, IHU_TIMESTAMP* StartTime, IHU_TIMESTAMP* EndTime, int* number_of_samples, IHU_DATA_SAMPLE** data_values);
...
long lRet = ReadRawDataByTime
(
tagname,//the handle returned from the connect
serverhandle, //the single tagname to retrieve
&temp_start_time, //start time for query
&temp_end_time, //end time for query
&number_of_samples, //will be set by API
&pSamples //will be allocated and populated in the user API
);
```
where tagname is defined as a string and the rest are their appropriate structs.
Now if I set the debugger in the C++ dll I can see all the values being passed in correctly, serverhandle is as expected, tagname holds the correct string, endTime has the correct time, number of samples and pSamples are blank as expected however startTime is 'undefined' when I am definitely passing in a valid struct.
If I dummy up the variables in the debugger it even returns expected data it just appears it is not passing the variables correctly.
I did some experimentation and swapped the order of the variables so serverhandle was passed first and tagname was passed second, if I do this all the variables are correct except tagname is now 'undefined'
is there something wrong with how I am passing the string that is corrupting the next variable? do I need to specifiy some special calling convention and currently it is just a fluke that everything else works?
Any help would be much appreciated. :)
edit: here is a screenshot of the debugger to show what I mean about all variables being passed except one.

5,024,485 | 1 | 5,024,525 | null | 2 | 4,587 | I have a parent div, and it houses a bunch of child divs. One of those is floated left, but the rest are floated right. It worked fine when only a few of the divs were floated right, but I've since added more and the results appear like this:
Light green is parent div background, other colors are the divs in question. A few actually float correctly for some reason, but green should be after the blue, and the pink after the red.
I have `overflow: hidden;` on the parent-most div, and the height has no affect on this child-div behavior.
How should I fix this?
Here's the relevant CSS:
```
#reviews {
background-color: #16ff21; //green
float: right;
text-align: left;
text-indent: 40px;
width: 40%;
height: 150px;
}
#rating {
background-color: #ff114b; //red
float: right;
width: 40%;
text-align: center;
font-size: 200%;
height: 150px;
}
#validFor {
background-color: #19ceff; //blue
float: right;
width: 40%;
text-align: center;
font-size: 200%;
height: 150px;
}
#stats {
background-color: #ffe8e5; //pink
width: 40%;
float: right;
vertical-align: middle;
text-align: center;
font-size: 250%;
}
```
Here's the parent div of all that up there:
```
#description {
text-align: left;
width: 100%;
}
```
And the parent div of #description:
```
#main {
background-color: #d3ffd3;
margin-left: auto;
margin-bottom: 0;
margin-right: auto;
padding: 10px;
width: 75%;

5,025,143 | 1 | null | null | 4 | 526 | I'm knee deep in font metrics with NSTextView at the moment. I was hoping a developer here could shed some light as to what's going on.
With Myriad Pro in a default NSTextView (dragged from IB and run in a fresh project), here's what you get:
Notice how the selected rect has the same height as the insertion point.
Now for behavior from Pages:
Notice how the selected rect is similar to the regular text view version, but the insertion point height is actually more reflective of the font (and smaller!).
Weird.
Why do I care? Here is a screen of my application with Helvetica, and then with Myriad:
Notice that in both cases, the outline symbol is perfectly centered with the insertion point height. Those symbols are actually subviews, and not in the text stream. Notice those symbols in Pages. They remain centered for Myriad. Clearly Apple realized something and fixed it. Any ideas what they did?

I followed a tutorial I found online to create a barcode scanning application where you press a button, it launches the scanner and then based on the results, the second button on the screen launches a URL with a passed variable through it. I developed the app myself in App Inventor so I could modify it to my needs, but I have encountered a problem. The barcode scanner launches, scans successfully (Product Found confirmation), but then upon returning to the main screen, the resultLabel.Text value is not changed and neither is the resultActionButton.Text value. Below is the block diagram of my application and a link to the tutorial I followed.

5,026,283 | 1 | null | null | 0 | 630 | I am using GLScene in my delphi project. I add some freeform on my scene (for example tooth). in the past I don't use material libs. I add my texture via the material property directrly of the freeform. Now I have to use materiallibs because I want to use some shader. But if I add a materiallib to my free from I get a ugly result from it. You can see the effect on this picture
Where is my mistake?
Thanks for any answer or tip

5,027,089 | 1 | null | null | 0 | 796 | I am currently following the procedural tutorial on creating procedural spheres found [here](http://iphonedevelopment.blogspot.com/2009/05/procedural-spheres-in-opengl-es.html) and I am trying to merge it with the textures tutorial with it to create a 3d version of Earth found [here](http://iphonedevelopment.blogspot.com/2009/05/opengl-es-from-ground-up-part-6_25.html).
So far, I was able to successfully bind the texture on the sphere. However, I am having some problems with the way it was displayed. I have attached links to the screen captures to further show the result. As you can see, the image is repeated and is not entirely wrapped on the sphere.
I am using this code, which I am guessing might cause the problem:
```
glTexCoordPointer(3, GL_FLOAT, 0, sphereTriangleStripVertices);
```
I hope you can help me with this as I have been trying to fix this for weeks now.
Thank you very much in advance.

5,027,204 | 1 | 6,857,600 | null | 17 | 2,935 | As a bit of background - Windows has a facility for Touch/TabletPCs whereby it shifts the position of popups/menus depending on your "handedness" (to prevent the menu appearing under your hand).
Essentially what this does is if you are set to "right handed" (which it seems to default to once you've connected a touch device), every popup you open is artificially kicked to the left - this causes massive layout issues where we try and line up a popup with the item it "popped up from" :
We can detect what this setting is set to with [SystemParameters.MenuDropAlignment](http://msdn.microsoft.com/en-us/library/system.windows.systemparameters.menudropalignment.aspx), and for trivial popups we can adjust this using the actual width of the popup - but for dynamic popups and when we throw right to left support into the mix, this just doesn't work.
Currently it's looking more likely that we are going to have to go through every popup, manually work out a value to adjust the kick, and add something like this to every one:
```
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding Source={x:Static SystemParameters.MenuDropAlignment}}" Value="True"/>
<Condition Binding="{Binding RelativeSource={RelativeSource Mode=Self}, Path=FlowDirection}" Value="RightToLeft"/>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="HorizontalOffset" Value="-50"/> <!-- Set to arbitrary value to test -->
</MultiDataTrigger.Setters>
</MultiDataTrigger>
```
So.. back to the question :-) Does anyone know of a way to stop a WPF popup looking at this setting at all?
For those that don't have a touch device you can access the Tablet PC settings by running:
C:\Windows\explorer.exe shell:::{80F3F1D5-FECA-45F3-BC32-752C152E456E}
And see the mess it makes for yourself :-)

```
convert 'input.pdf[0]' -resize "100x140>" -colorspace 'rgb' 'output.jpg' 2>/dev/null

Some of the PDFs are in CMYK color space, hence the specification of the expected -colorspace as rgb. This was working fine until I updated to the latest versions of Imagemagick(6.6.7-1) and ghostscript(9.01_0), now it looks like the conversion to rgb isn't working any longer, here is an example output:
(The background should be white, not black)
It seems though that the problem comes from the -resize option because if I remove it the output is correct.
To get the expected output I now do two passes, the first to convert to rgb and the second to resize the image, but that's not very elegant. Is there a better solution?

Basically what I want to do is the following: My C# WPF application contains a ListView with some entries and each of the entry gets validated. Depending on the outcome of the validation, such a green check mark or a red cross should be displayed.
I found a very nice red cross in the class SystemIcons. It is called SystemIcons.Error. The SystemIcons class also provides other icons like "Exclamation", "hand", "Shield", "Question" and various other icons, however there is no such a check mark thing.
Does anyone know whether such a check mark icon exists in some default library? I googled but I could not find anything alike. In case there is no such Icon, I would have to take some image from the web (like I posted here), but that would be the last option since my application should look consistent and I'm pretty sure Microsoft uses lots of those green things in many places of Windows. So there must be some icon I could use, right?

} else {

return 0;
}
return [category.records count];

5,030,315 | 1 | 5,074,263 | null | 31 | 12,897 | This question is about iOS device rotation and multiple controlled views in a UINavigationController. Some views should be orientation, and some should . If you try and create the simplest setup with three views, you'll notice that the autorotation behavior has a few very nasty quirks. The scenario is, however, very simple, so I think I'm either not doing the autorotation implementation correctly, or I'm forgetting something.
I have a very basic demo app that shows the weirdness, and I made a video showing it in action.
- [Download the app (XCode project)](http://grabs.epologee.com/86a550fe0c65cd7d8ab0b3c346a342f7.zip)- [View the classes as a gist (rather lengthy)](https://gist.github.com/b8670e5976635a629842)- [Watch the question video (YouTube, 2m43s)](http://www.youtube.com/watch?v=pugXOhTbJaY)
The setup is very basic: Three view controllers called `FirstViewController`, `SecondViewController` and `ThirdViewController` all extend an `AbstractViewController` that shows a label with the class' name and that return YES for `shouldAutorotateToInterfaceOrientation:` when the device is in portrait orientation. The SecondViewController overrides the this method to allow for all rotations. All three concrete classes add a few colored squares to be able to navigate between the views by pushing and popping the controllers onto/off the `UINavigationController`. So far a very simple scenario, I would say.
If you hold the device in portrait or landscape orientation, this is the result I would not only like to achieve, but would also expect. In the first image you see that all views are 'upright', and in the second you see that only the second view controller counter-rotates the device's orientation. To be clear, it should be possible to navigate from the second view in landscape mode to the third, but because that third only supports portrait orientation, it should only be shown in portrait orientation. The easiest way to see if the results are alright, is by looking at the position of the carrier bar.
But this question is here because the actual result is completely different. Depending on what view you're at when you rotate the device, and depending on what view you navigate to next, the views will not rotate (to be specific, the `didOrientFromInterfaceOrientation:` method is never called). If you're in landscape on the second and navigate to the third, it will have the same orientation as the second (=bad). If you navigate from the second back to the first however, the screen will rotate into a 'forced' portrait mode, and the carrier bar will be at the physical top of the device, regardless of how you're holding it. The video shows this in more detail.
My question is twofold:
1. Why does the first view controller rotate back, but not the third?
2. What needs to be done to get the correct behavior from your views when you only want some views to autorotate, but not others?
Cheers,

5,030,389 | 1 | null | null | 21 | 34,883 | This question is a continuation of the previous [question](https://stackoverflow.com/questions/5027480/how-to-add-a-new-column-and-aggregate-values-in-r) I asked.
Now I have a case where there is also a category column with Prop. So, the dataset becomes like
```
Hour Category Prop2
00 A 25
00 B 59
00 A 55
00 C 5
00 B 50
...
01 C 56
01 B 45
01 A 56
01 B 35
...
23 D 58
23 A 52
23 B 50
23 B 35
23 B 15
```
In this case I need to make a stacked area plot in R with the percentages of these different categories for each day. So, the result will be like.
```
A B C D
00 20% 30% 35% 15%
01 25% 10% 40% 25%
02 20% 40% 10% 30%
.
.
.
20
21
22 25% 10% 30% 35%
23 35% 20% 20% 25%
```
So now I would get the share of each Category in each hour and then plot this is a stacked area plot like this where the x-axis is the hour and y-axis the percentage of Prop2 for each category given by the different colours

I have a `SearchModel` class that my view inherits from
```
public class SearchModel
{
public String Something { get; set; }
public List<SearchField> SearchFields { get; set; }
}
public class SearchField
{

I have a controller called `SearchController`
```
public ActionResult Index()
{
SearchModel model = new SearchModel
{
Something = "Hello",
SearchFields = customer.Config.Fields
};
return View(model);
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(SearchModel searchModel)
{
return View("Index", searchModel);
}
```
The SearchController index page has this to render the fields
```
<% using (Html.BeginForm())
{%>
<%= Html.TextBox("Something", Model.Something) %>
<% for (int i = 0; i < Model.SearchFields.Count; i++)
{

<%= Html.ValidationMessageFor(x => x.SearchFields[i].Value) %>
<% } %>
<button type="submit" value="Search" class="SearchBtn">
Search</button>
<% } %>
```
When I modify the value of the SearchField .Value property and press the submit button, it posts to the `public ActionResult Index(SearchModel searchModel)` method.
The searchModel variable contains the collection `SearchFields`, however only the "`Value`" and "`FilterOperator`" properties are not null.
How can I include the other properties in the post, even if I don't want to explicitly list them in the form?

It has been sometime since this keep popping in and I never had the time to ask why:
so here is my very simple HTML:
```
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Page Title</title>
<style>
div{
width: 200px;
background: green;

background: yellow;
margin: 40px;
}
</style>
</head>
<body>
<div>
<p>Testing</p>
</div>
</body>
</html>
```
nothing particular, only a simple page with a div and a paragraph inside that div.
but you can notice that on the css I declared the paragraph to stay away 40px from divs bounds...and this happens
That's right...top and bottom margin being ignored....
but then if I add a 1px red border to the `div` like:
```
div{
width: 200px;
background: green;
border: 1px solid red;
}
```
here's what I get:
so yes, it really sounds weird for me...this is happening in safari, but I am sure it will happen the same on other browsers...my question would be..why this is happening?
Is there any way to fix it?

I have a MySQL database containing a table of rentable properties and a table of bookings for these properties. There is also a search feature for finding available properties between two provided dates. When searching, the user can enter the start date, the amount of days they wish to stay, and a date flexibility of up to +/- 7 days. A booking can start on the same day as another booking ends (party 1 leaves in the morning, party 2 arrives in the evening).
I am having difficulty implementing the flexibility feature efficiently.
```
CREATE TABLE IF NOT EXISTS `property` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`name` varchar(60) COLLATE utf8_unicode_ci DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
CREATE TABLE IF NOT EXISTS `property_booking` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`property_id` bigint(20) DEFAULT NULL,
`name` varchar(60) COLLATE utf8_unicode_ci DEFAULT NULL,
`date_start` date DEFAULT NULL,
`date_end` date DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
```
```
INSERT INTO `property` (`name`)
VALUES ('Property 1'), ('Property 2'), ('Property 3');
INSERT INTO `property_booking` (`property_id`,`name`,`date_start`,`date_end`)
VALUES (1, 'Steve', '2011-03-01', '2011-03-08'),
(2, 'Bob', '2011-03-13', '2011-03-20'),
(3, 'Jim', '2011-03-16', '2011-03-23');
```
The user selects that they want to start their stay on 2011-03-10, they want to stay for 7 days, and they have a flexibility of +/- 2 days. I have compiled an image that visualises the data and parameters below.
Property 1
Property 3
My current query checks for overlap for all 7 day date ranges within the total searchable date range, like this:
```
SELECT p.`id`, p.`name`
FROM `property` p
WHERE (NOT (EXISTS (SELECT p2.`name` FROM `property_booking` p2 WHERE (p2.`property_id` = p.`id` AND '2011-03-10' < DATE_SUB(p2.`date_end`, INTERVAL 1 DAY) AND '2011-03-17' > DATE_ADD(p2.`date_start`, INTERVAL 1 DAY)))))
OR (NOT (EXISTS (SELECT p3.`name` FROM `property_booking` p3 WHERE (p3.`property_id` = p.`id` AND '2011-03-11' < DATE_SUB(p3.`date_end`, INTERVAL 1 DAY) AND '2011-03-18' > DATE_ADD(p3.`date_start`, INTERVAL 1 DAY)))))
OR (NOT (EXISTS (SELECT p4.`name` FROM `property_booking` p4 WHERE (p4.`property_id` = p.`id` AND '2011-03-09' < DATE_SUB(p4.`date_end`, INTERVAL 1 DAY) AND '2011-03-16' > DATE_ADD(p4.`date_start`, INTERVAL 1 DAY)))))
OR (NOT (EXISTS (SELECT p5.`name` FROM `property_booking` p5 WHERE (p5.`property_id` = p.`id` AND '2011-03-12' < DATE_SUB(p5.`date_end`, INTERVAL 1 DAY) AND '2011-03-19' > DATE_ADD(p5.`date_start`, INTERVAL 1 DAY)))))
OR (NOT (EXISTS (SELECT p6.`name` FROM `property_booking` p6 WHERE (p6.`property_id` = p.`id` AND '2011-03-08' < DATE_SUB(p6.`date_end`, INTERVAL 1 DAY) AND '2011-03-15' > DATE_ADD(p6.`date_start`, INTERVAL 1 DAY)))));
```
On the sample dataset, it's reasonably quick, but on much larger datasets it's going to get pretty sluggish, even more so when you build the full +/- 7 day flexibility.
Does anyone have any suggestions as to how this query could be better written?

The divs have to be positioned adjacent to the field. I am trying to position using absolute position as can be seen in css above for #duplicateMobileAlert. The problem is the div is getting cut beyond the tr. So if I change left:10px to left:-90px most of the div disappears behind the container. I want it to go over the tr and its container.
How can I do that? Any pointers?

5,032,058 | 1 | 5,033,920 | null | 3 | 1,853 | What's the correct way to track mouse position, from Adobe Flash, when someone has:
1. Started a drag within the Flash application (a MOUSE_DOWN event),
2. Dragged the mouse outside the app or even the browser window (a MOUSE_MOVE event), and
3. Released the mouse button (a MOUSE_UP event)?
For example (imagine Stack Overflow is a Flash application):
Within the app, I'm able to track the mouse X and Y positions with a MOUSE_MOVE event listener, but I lose it when it goes outside of the browser...
So, how do I track the position of the mouse no matter where it goes?
For a good example, try [Google Finance](http://www.google.com/finance?q=INDEXSP:.INX). Try dragging the chart around; it'll still drag around if you move your mouse out of the browser window, and the mouse will be outside of the browser when you release it.
Also, check out [KOKO KAKA](http://www.kokokaka.com/); If you click on the scrollbar (make the browser window really small) and move outside of the browser window, the scroll bar moves just like a real one would.
I believe both only work because the MOUSE_DOWN event "captures" the mouse, allowing the Flash application to track the position of the mouse even when it is outside of the browser.
How would you be able to keep the event fired like this??
Thanks! ♥

The next step is to exponentiate it, but it is very large, so I need to do some reductions on it. Specifically it contains a lot of symmetry. Below are some examples on how many nodes can be eliminated by simple observations.
My question is whether there is an algorithm to efficiently eliminate symmetry in digraphs, similarly to the way I've done it manually below.
In all cases the initial vector has the same value for all nodes.
---
In the first example we see that `b`, `c`, `d` and `e` all receive values from `a` and one of each other. Hence they will always contain an identical value, and we can merge them.

In this example we quickly spot, that the graph is identical from the point of view of `a`, `b`, `c` and `d`. Also for their respective sidenodes, it doesn't matter to which inner node it is attached. Hence we can reduce the graph down to only two states.
---
Some people were reasonable enough not quite sure what was meant by "State transfer matrix". The idea here is, that you can split a combinatorial problem up into a number of state types for each `n` in your recurrence. The matrix then tell you how to get from `n-1` to `n`.
Usually you are only interested about the value of one of your states, but you need to calculate the others as well, so you can always get to the next level. In some cases however, multiple states are symmetrical, meaning they will always have the same value. Obviously it's quite a waste to calculate all of these, so we want to reduce the graph until all nodes are "unique".
Below is an example of the transfer matrix for the reduced graph in example 1.
```
[S_a(n)] [1 1 1] [S_a(n-1)]
[S_f(n)] = [1 0 0]*[S_f(n-1)]
[S_B(n)] [4 0 1] [S_B(n-1)]
```

```
<style

I want to be able to link an Action Script event to clicking text within a text box.The only thing I can see is to just create a basic Hyper Link, but not apply any action:
I have been messing around for over an hour but just can't see a way to apply actionscript and all the tutorials on the internet seem to target ActionScript 3 or not do exactly what I want.
The reason for this is that there is background music to the site and when YouTube is launched, it needs to be muted. I know the code to mute and have done this on custom objects before, but I can't see any way to apply script to a textbox hyperlink.
Whilst I would ideally like to do it this way, I am happy to consider any solution resulting in opening a page and muting the site.
To be honest, I tried doing a quick switch to AS3, but as there are so many problems that would need addressing, I would rather spend the time converting the site to HTML/Jquery or even Silverlight.... I just hope there is something small I have overlooked which can get this done without too many changes needed.

5,035,031 | 1 | 5,035,161 | null | 0 | 1,798 | Does anyone know if Tomcat running inside of Eclipse truly uses the `<tomcat>\bin\` directory when you've configured your server to use your local Tomcat install (Server view) inside Eclipse?

5,035,120 | 1 | 5,035,266 | null | 14 | 9,307 | I am trying to animate the color the the text on a UILabel to pulse from: [Black] to [White] to [Black] and repeat.
```
- (void)timerFlash:(NSTimer *)timer {
[[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:0.0]];
[UIView animateWithDuration:1
delay:0
options:UIViewAnimationOptionAllowUserInteraction
animations:^{[[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:1.0]];}
completion:nil];
}
```
.
```
[self setFadeTimer:[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerFlash:) userInfo:nil repeats:YES]];
```
Firstly I am not sure of my method, my plan (as you can see above) was to set up a animation block and call it using a repeating NSTimer until canceled.
My second problem (as you can see above) is that I am animating from black (alpha 0) to white (alpha 1) but I don't know how to animate back to black again so the animation loops seamlessly
Essentially what I want is the text color to pulse on a UILabel until the user presses a button to continue.
# EDIT_001:
I was getting into trouble because you can't animate [UILabel setColor:] you can however animated [UILabel setAlpha:] so I am going to give that a go.
# EDIT_002:
```
- (void)timerFlash:(NSTimer *)timer {
[[self navTitle] setAlpha:0.5];
[UIView animateWithDuration:2
delay:0
options:UIViewAnimationOptionAllowUserInteraction
animations:^{[[self navTitle] setAlpha:0.9];}
completion:nil];
}
```
This works (BTW: I do want it to stop which is why I hooked it up to a NSTimer so I can cancel that) the only thing is that this animates from midGray to nearWhite and then pops back. Does anyone know how I would animate back from nearWhite to midGray so I get a nice smooth cycle?
# EDIT_003: (Solution)
The code suggested by Dave DeLong (see below) does indeed work when modified to use the CALayer opacity style attribute:
```
UILabel *navTitle;
@property(nonatomic, retain) UILabel *navTitle;
```
.
```
// ADD ANIMATION
CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"opacity"];
[anim setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[anim setFromValue:[NSNumber numberWithFloat:0.5]];
[anim setToValue:[NSNumber numberWithFloat:1.0]];
[anim setAutoreverses:YES];
[anim setDuration:0.5];
[[[self navTitle] layer] addAnimation:anim forKey:@"flash"];
```
.
```
// REMOVE ANIMATION
[[[self navTitle] layer] removeAnimationForKey:@"flash"];
```

I want to display an image in the section header along with some caption text, something similar to what instagram and many other application does. I tried using the sample from `TTNavigatorDemo` to display data from `TTSectionedDatasource`, (I am not sure if this is the right way to do it, please suggest some better way if you know any). It contains section name/headers as regular strings and data as `TTTableViewItem`. I tried implementing `<UITableViewDelegate>` protocol and achieved it using `viewForHeaderInSection` method, now the data is separated from section, Is there any better way using [Three20](http://three20.info) through which I can pass on my Header/Section view and `TableItemView` along in a datasource as it would allow me to implement the `TTTableViewDragRefreshDelegate`, which I was not able to implement when implementing the `<UITableViewDelegate>` protocol in my class.
My class declaration right now, looks something like
```
@interface ImageTable : TTTableViewController <UITableViewDelegate> { }
```
I would like to show section headers with image and text like:
:
I am currently using the `TTNavigatorCode` to populate the data in my
Table which is:
```
self.dataSource = [TTSectionedDataSource dataSourceWithObjects:
@"Food"
[TTTableViewItem itemWithText:@"Porridge" URL:@"tt://food/porridge"],
[TTTableTextItem itemWithText:@"Bacon & Eggs" URL:@"tt://food/baconeggs"],
[TTTableTextItem itemWithText:@"French Toast" URL:@"tt://food/frenchtoast"],
@"Drinks",
[TTTableTextItem itemWithText:@"Coffee" URL:@"tt://food/coffee"],
[TTTableTextItem itemWithText:@"Orange Juice" URL:@"tt://food/oj"],
@"Other",
[TTTableTextItem itemWithText:@"Just Desserts" URL:@"tt://menu/4"],
[TTTableTextItem itemWithText:@"Complaints" URL:@"tt://about/complaints"],
@"Other",
[TTTableTextItem itemWithText:@"Just Desserts" URL:@"tt://menu/4"],
[TTTableTextItem itemWithText:@"Complaints" URL:@"tt://about/complaints"],
nil];
```
I was able to make something similar by implementing the method:
```
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
return myCustomView;
}
```
But since my data is coming from the Model Class and I want my generate views and add them to datasource in a formatted way. I would like to know if there is a way using Three20 through which I specify an Array of my data for sections and another array for corresponding data under the sections?

But I get triangulated shading or flat color on the cube located at origin ( center) and rotated 45 deg around x and y. So the cube is directly in front of the light. Any reasons why I am getting such poor results? Attached is the cube image.

Can do each individually:
Series Label Properties, Label data: #PERCENT{p0}
or: =Fields!DayOfWeek.Value
How to display both?

5,036,398 | 1 | 5,036,472 | null | 1 | 3,612 | I am interested in seeing if I can use the `:before` pseudo-element on a `<a href` wrapped around a `<button>` element?
Currently, Firefox shows a thin blue line behind the `<button>` element - this is due to it being wrapped in an `<a href`.
If I use an within the `<a href` the line goes away:
```
<a href="#" style="text-decoration:none;"><button>
```
However, since I have `<button>` elements on multiple pages, I want to target them using if possible (and I don't particularly want to go and add a class to all the `<a href` that are wrapping the `<button>`'s on the site). This is where I was thinking the `:before` pseudo-element would come in handy but it doesn't seem to work:
```
a:before button{
text-decoration:none !important;
}
```
This is how the `<button>`'s display in Firefox, see the blue default text-decoration applied to the `<a href`. The reason it is showing up only on the right hand side is because a class of `margin-left:5px` is applied to the `<button>` element:
Here's a basic version of the buttons up on jsfiddle (ignore slight appearance differences): [http://jsfiddle.net/Vtjue/2/](http://jsfiddle.net/Vtjue/2/)
Any ideas?
