4,601,318 | 1 | 4,601,384 | null | 1 | 1,047 | Sorry about the title. I'm not sure how to properly describe the problem.
I have four tables, tables A, B, X and D. A and B have a many-to-many relationship so I'm using X as the link table.
Here's the structure:
Assuming all I have is an ID corresponding to a row in table A, I want to select the rows in table B that match up with that ID plus a count of all rows in table D that have the same `b_id`. Eh, I suck at explaining in words.
Here's what I would like ( -- let's just say I have an "A"):
```
-------------------------------------------------------------
| b.id | (A COUNT of how many rows in D have a b_id = b.id) |
-------------------------------------------------------------
| 1 | 20 |
-------------------------------------------------------------
| 4 | 12 |
-------------------------------------------------------------
```
So, according to the above results, this particular "A" has two "B"s. One of those "B"s has 20 "D"s and the other has 12 "D"s.
How can I write a single query to give me the results I'm after (again, all I'm searching with is an ID in table A)?

4,601,317 | 1 | 4,603,367 | null | 30 | 8,135 | My UI has an unordered list on the left. When a list item is selected, a `div` appears on the right of it. I'd like to have a curved where the `<li>` and the `<div>` meet. Some people call this a or an . See the white arrow in the image below.
To extend the blue `<li>` to the edge of the `<ul>`, I'm planning to do something like this:
```
li {
right-margin: 2em;
border-radius: 8px;
}
li.active {
right-margin: 0;
border-bottom-right-radius: 0;
border-top-right-radius: 0;
}
```
Is there a better way to extend the `<li>` to the edge of the `<ul>`? Obviously, I'll include the webkit and mozilla border radius CSS as well.
The main thing I'm unsure about is that underneath the bottom right corner of the active `<li>`. I have some ideas, but they seem like hacks. Any suggestions?
NOTE that the `<ul>` is indicated in grey, but it would be white in the real design. Also, I'm planning to use Javascript to position the `<div>` correctly when an `<li>` is selected.

4,602,934 | 1 | null | null | 5 | 722 | I am using [Code Contracts](http://research.microsoft.com/en-us/projects/contracts/) together with the [Code Contracts Editor Extensions](http://visualstudiogallery.msdn.microsoft.com/en-us/85f0aa38-a8a8-4811-8b86-e7f0b8d8c71b) VS2010 add-in. I have a class that implements the `IEnumerable<T>` interface, and I've implemented an iterator block for the `GetEnumerator()` method. Above it, I can see the following inherited contract:
![ensures result != null ensures result.Model == ((IEnumerable)this).Model [Pure] public IEnumerator(of IBaseMessage) GetEnumerator() { ](https://i.stack.imgur.com/rh39r.png)
I understand the first and third contract requirement - `GetEnumerator()` must never return a null, and it must never cause a side-effect. But what does the second contract requirement mean? What is this `Model` property of `IEnumerator<T>` and of `IEnumerable`?
As Damien_The_Unbeliever pointed out in his comment, the contract for `IEnumerable<T>` and `IEnumerator<T>` are located in a seperate file, a Contracts Reference Assembly. Using [Reflector](http://www.red-gate.com/products/dotnet-development/reflector/), in the disassembly of the contract of those two interfaces (the full code is [here](http://pastebin.com/8sAmk7ee)), you can see the following:
```
[return: Fresh]
[Escapes(true, false), Pure, GlobalAccess(false)]
public IEnumerator GetEnumerator()
{
IEnumerator enumerator;
Contract.Ensures((bool) (Contract.Result<IEnumerator>() != null), null, "Contract.Result<IEnumerator>() != null");
Contract.Ensures((bool) (Contract.Result<IEnumerator>().Model == this.Model), null, "Contract.Result<IEnumerator>().Model == this.Model");
Contract.Ensures((bool) (Contract.Result<IEnumerator>().CurrentIndex == -1), null, "Contract.Result<IEnumerator>().CurrentIndex == -1");
return enumerator;
}
```
Interestingly, there's an additional contract in `GetEnumerator()` that isn't displayed by the editor extention:
```
Contract.Result<IEnumerator>().CurrentIndex == -1
```
And some additionaly mysteries (such as the `Fresh`, `Escapes` and `GlobalAccess` attributes).

4,604,647 | 1 | 4,607,784 | null | 3 | 14,028 | In my iOS application, I want to provide a settings-view. "presentModalViewController" works very well:
```
ViewSettings *controller = [[ViewSettings alloc] initWithNibName:@"ViewSettings" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
[self.navigationController presentModalViewController:navController animated:YES];
[controller release];
[navController release];
```
Unfortunately, I have to change my running code and create the ViewSettings including the UINavigationController in Interface Builder. Why? Long story, I'll explain it in the end of this thread...
I try to drag and drop an UINavigationController in my ViewSettings and create an IBOutlet to access it in my class. I give this controller to "presentModalViewController" but the application crashed...
What I'm doing wrong?

Error Message:
The error happens in the last line of this code:
```
ViewSettings *viewSettings = [[ViewSettings alloc] initWithNibName:@"ViewSettings" bundle:nil];
UINavigationController *navController = viewSettings.navigationController;
UINavigationBar *navBar = navController.navigationBar;
OwnNavigationBar *ownNavBar = (OwnNavigationBar *)navBar;
[ownNavBar drawHeaderImage:YES];
[self.navigationController presentModalViewController:navController animated:YES];
```
Detailed Error:

Thanks for your help!
Yes, navigationController is nil...
I think I add the UINavigationController in a wrong way... I put it in this window, because it was not possible to put it directly in my view:
How do I add the UINavigationController correct?
---
## PS: Why do I have to use IB? (you can skip this...)
I need an background image in my UINavigationBar. My first try was:
```
UIImage *image = [UIImage imageNamed: @"header.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
[self.navigationController.navigationBar addSubview:imageView];
[self.navigationController.navigationBar sendSubviewToBack:imageView];
```
But in some issues, the title oder a UIBarButton is not visible! I tried a lot, e.g. sets the "tag" of the view and sendSubviewToBack in each view, but no success. This is a very annoying bug!
My second try was to create a category and overwrite the drawRect-method:
```
@implementation UINavigationBar(MyNavigationBar)
- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed: @"header.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
@end
```
But now, all of my UINavigationBars have an background image and I can't deactivate it. The problem is, that "ViewSettings" needs the background image, but the following pushed views do not.
Unfortunately, it isn't possible to set a property in a category or call [super drawRect:rect] to avoid painting the image.
My last try is to write an own UINavigationBar
```
@interface OwnNavigationBar : UINavigationBar {
BOOL _drawHeaderImage;
}
```
Now I can control the drawRect-method!! GREAT!!
```
- (void)drawRect:(CGRect)rect {
if (_drawHeaderImage) {
UIImage *image = [UIImage imageNamed: @"header.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
else {
[super drawRect: rect];
}
}
```
But I celebrate to early... :-(
It isn't possible to set an own UINavigationBar in the UINavigationController!!!
"navigationBar" in UINavigationController is a read-only property!
AAAAHHHHHHHHHH!
I have one last chance: in Interface Builder it is possible to give an UINavigationController an own UINavigationBar!!
YES! I GOT IT!! :-)
I configured it in my MainWindow_iPhone.xib and it works great!
Now, I have to implement this for my ViewSettings, because this (modal) view needs a new UINavigationController.

4,605,015 | 1 | null | null | 3 | 1,143 | I wrote an application which detects a square within an image. To give you a good understanding of how such an image containing such a square, in this case a marker, could look like:
What I get, after the detection, are the coordinates of the four corners of my marker. Now I don't know how to display an object on my marker. The object should have the same rotation/angle/direction as the marker.
Are there any papers on how to achieve that, any algorithms that I can use that proofed to be pretty solid/working?
It doesn't need to be a working solution, it could be a simple description on how to achieve that or something similar. If you point me at a library or something, it should work under linux, windows is not needed but would be great in case I need to port the application at some point.
I already looked at the ARToolkit but they you camera parameter files and more complex matrices while I only got the four corner points and a single image instead of a whole video / camera stream.

4,605,325 | 1 | 4,607,824 | null | 15 | 13,047 | I'm beating my head against a wall here, and I'm fairly certain I'm doing something stupid, so time to make my stupidity public.
I'm trying to take two images, blend them together into a third image using standard blending algorithms (Hardlight, softlight, overlay, multiply, etc).
Because Android does not have such blend properties build in, I've gone down the path of taking each pixel and combine them using an algorithm. However, the results are garbage. Below is the results of a simple multiply blend (images used, and expected result).
BASE: 
BLEND: 
EXPECTED RESULT: 
GARBAGE RESULT: 
Any help would be appreciated. Below is the code, which I've tried to strip out all the "junk", but some may have made it through. I'll clean it up if something isn't clear.
```
ImageView imageView = (ImageView) findViewById(R.id.ImageView01);
Bitmap base = BitmapFactory.decodeResource(getResources(), R.drawable.base);
Bitmap result = base.copy(Bitmap.Config.RGB_565, true);
Bitmap blend = BitmapFactory.decodeResource(getResources(), R.drawable.blend);
IntBuffer buffBase = IntBuffer.allocate(base.getWidth() * base.getHeight());
base.copyPixelsToBuffer(buffBase);
buffBase.rewind();
IntBuffer buffBlend = IntBuffer.allocate(blend.getWidth() * blend.getHeight());
blend.copyPixelsToBuffer(buffBlend);
buffBlend.rewind();
IntBuffer buffOut = IntBuffer.allocate(base.getWidth() * base.getHeight());
buffOut.rewind();
while (buffOut.position() < buffOut.limit()) {
int filterInt = buffBlend.get();
int srcInt = buffBase.get();
int redValueFilter = Color.red(filterInt);
int greenValueFilter = Color.green(filterInt);
int blueValueFilter = Color.blue(filterInt);
int redValueSrc = Color.red(srcInt);
int greenValueSrc = Color.green(srcInt);
int blueValueSrc = Color.blue(srcInt);
int redValueFinal = multiply(redValueFilter, redValueSrc);
int greenValueFinal = multiply(greenValueFilter, greenValueSrc);
int blueValueFinal = multiply(blueValueFilter, blueValueSrc);
int pixel = Color.argb(255, redValueFinal, greenValueFinal, blueValueFinal);
buffOut.put(pixel);
}
buffOut.rewind();
result.copyPixelsFromBuffer(buffOut);

4,605,432 | 1 | 4,617,926 | null | 3 | 9,216 | I have two images that I want to display on top of each other. one image a single channel image and the second image is a RGB image but with most of the area being transparent.
How these two images are generated in different functions. I know to just display these on top of each other, i can use the same window name when calling `cvShowImage()` but this doesn't work when they are drawn from different functions. When trying this, I used `cvCvtcolor()` to convert he binary image from single channel to RGB and then displaying the second image from another function. But this didn't work. Both images are same dimension, depth and number of channels (after conversion).
I want to avoid passing in one image into the second function and then draw them. So I'm looking for a quick dirty trick to display these two images overlapped.
Thank you

How do I keep the item to stay where it's at when the animation ends?

What I really want is free floating wheel that responds to user swiping. When the user swipes to the left on the wheel, the wheel spins to the left. Depending on the speed of the swipe, the wheel spins faster and then starts to slow down. If anyone can give some hints or directions on this, I would be greatly appreciative.

4,605,897 | 1 | 4,605,966 | null | 0 | 742 | I'm making a website and I have this HTML for a bar chart:
```
<div class="chart">
<meter style="height: 160px;">80%</meter>
<meter style="height: 86px;">43%</meter>
<meter style="height: 128px;">64%</meter>
<meter style="height: 172px;">86%</meter>
<meter style="height: 70px;">35%</meter>
<meter style="height: 52px;">26%</meter>
</div>
```
To make this into a nice bar chart, I use this CSS:
```
div.chart {
background-color: #343434;
height: 200px;
padding: 10px;
}
div.chart meter {
display: inline-block;
background-color: #892399;
border-top: solid 1px #AB34CB;
color: #FFFFFF;
outline: solid 1px #670034;
text-align: center;
width: 60px;
vertical-align: text-bottom;
}
```
Because none of the bars in the chart is 100%, and thus 200px, there is a gap between the bottom of the chart container and the bars:
The only way to fix this I could think of is either by using JavaScript, or by inserting some aweful div after the bars that has a width of 1px and `visibility: hidden;` set, but this screws up my HTML.
How can I fix this in another way while retaining my HTML as is?

4,606,438 | 1 | 4,606,459 | null | 2 | 5,906 | I have designed an analog clock control. It uses the stroke from two ellipses to represent an outer border and an inner border to the clock face.
I have exposed properties in the UserControl that allow a user to alter the thickness of these two borders. The Ellipse.StrokeThickness properties are then bound to these UserControl properties. At the moment, I am binding the UserControl property for the outer border thickness to the margins of the inner elements so that they are not hidden when the border size is increased.
```
<Ellipse Name="OuterBorder" Panel.ZIndex="1" StrokeThickness="{Binding OuterBorderThickness,
ElementName=This}" Stroke="{StaticResource OuterBorderBrush}" />
<Ellipse Name="InnerBorder" Panel.ZIndex="5" StrokeThickness="{Binding InnerBorderThickness,
ElementName=This}" Margin="{Binding OuterBorderThickness, ElementName=This}"
Stroke="{StaticResource InnerBorderBrush}">
...
<Ellipse Name="Face" Panel.ZIndex="1" Margin="{Binding OuterBorderThickness, ElementName=This}"
Fill="{StaticResource FaceBackgroundBrush}" />
...
```
The problem is that if the inner border thickness is increased, this does not affect the margins and so the hour ticks and numbers can become partially obscured or hidden. So what I really need is to be able to bind the margin properties of the inner controls to the sum of the inner and outer border thickness values (they are of type double).
I have done this successfully using 'DataContext = this;', but am trying to rewrite the control without this as I hear it is not recommended. I also thought about using a converter and passing the second value as the ConverterParameter, but didn't know how to bind to the ConverterParameter. Any tips would be greatly appreciated.
EDIT>>
Thanks to Kent's suggestion, I've created a simple MultiConverter to add the input values and return the result. I've hooked the SAME multibinding with converter XAML to both a TextBlock.Text property and the TextBlock.Margin property to test it.
```
<TextBlock>
<TextBlock.Text>
<MultiBinding Converter="{StaticResource SumConverter}" ConverterParameter="Add">
<Binding Path="OuterBorderThickness" ElementName="This" />
<Binding Path="InnerBorderThickness" ElementName="This" />
</MultiBinding>
</TextBlock.Text>
<TextBlock.Margin>
<MultiBinding Converter="{StaticResource SumConverter}" ConverterParameter="Add">
<Binding Path="OuterBorderThickness" ElementName="This" />
<Binding Path="InnerBorderThickness" ElementName="This" />
</MultiBinding>
</TextBlock.Margin>
</TextBlock>
```
I can see the correct value displayed in the TexBlock, but the Margin is not set. Any ideas?
EDIT >> >>
Interestingly, the Margin property can be bound to a data property of type double, but this does not seem to apply within a MultiBinding. As advised by Kent, I changed the Converter to return the value as a Thickness object and now it works. Thanks Kent.

4,606,680 | 1 | 4,612,946 | null | 15 | 9,187 | I'm creating a drawing app ( text ) for the iPad using OpenGL. I've already had a look at Apple's example GLPaint, and my app is now based on that code. My app should be just for drawing text, not for painting pictures.
Well, my App works, I can write some text. But the writing isn't really good, it doesn't make fun to write. The drawing path isn't smooth, it's angularly because I'm drawing a line from one point to another. And the path has everywhere the same width. My idea is: when you're writing fast the line is thinner than when you're writing slow. It should be the same experience like writing with a real pen.
How can I make the path look much smoother? How can I vary the width of the line depending on the speed of writing?
Here you can see what I mean:

4,607,391 | 1 | 4,608,178 | null | 1 | 609 | Recently I was pulled into the boss-man's office and told that one of my queries was slowing down the system. I then was told that it was because my `WHERE` clause began with `1 = 1`. In my script I was just appending each of the search terms to the query so I added the `1 = 1` so that I could just append `AND` before each search term. I was told that this is causing the query to do a full table scan before proceeding to narrow the results down.
I decided to test this. We have a `user` table with around 14,000 records. The queries were ran five times each using both phpmyadmin and PuTTY. In phpmyadmin I limited the queries to 500 but in PuTTY there was no limit. I tried a few different basic queries and tried clocking the times on them. I found that the `1 = 1` seemed to cause the query to be faster than just a query with no `WHERE` clause at all. This is on a live database but it seemed the results were fairly consistent.
I was hoping to post on here and see if someone could either break down the results for me or explain to me the logic for either side of this.

4,607,546 | 1 | null | null | 2 | 683 | I'm trying to make a Flex (Advanced)DataGrid component with some mechanism where the user can toggle the visibility of the columns. I've crudely implemented this by reading in the columns into the right-click menu, and when a column name is selected here, the visibility is toggled. It works, but it's not the most elegant solution.
Specifically, I'm trying to emulate the "datagrid" that Mozilla Thunderbird uses to display emails. Here is an image:
In the upper right, there is an icon over the scroll bar. If there is no scrollbar, the icon remains in the same place. When clicking the icon, it opens up a menu that shows all the possible columns, with the visible ones having a check mark next to them, like this:
Also, the scroll bar always appears under this button, never "pushing" it over into it's own column.
I'd like to re-create this in Flex. I believe the menu part and creating a column with a button headerRenderer is easy enough. But I can't figure out how (if at all possible) to do this with the scrollbar, because the scrollbar always seems to be "its own column". Any ideas or help would be appreciated. Thank you.

1. The second line is not scrolling.
2. The button does not show up.
Is there by any chance a simple WYSIWYG editor for layout? Or is there an app to give me a quick view of my layout XML? Something like FireBug in FireFox would be fine.
Barring the slim chance there are UI helpers for Droid, what am I doing wrong? :)
: I found and the button is not showing up at all (visible) though it does show in the heirarchy. [http://screencast.com/t/rdjaR0tCM6](http://screencast.com/t/rdjaR0tCM6)

Here it should draw two bounding boxes for the blob on the right and separately for the one of the left. I agree they are close but enough distance in between them. I'm only drawing External contours instead of the tree or list. I'm also using cvFindNextContour(contourscanner) as this is a easier implementation for my case.

4,608,278 | 1 | 7,737,475 | null | 16 | 33,173 | [According to quirks mode](http://www.quirksmode.org/css/display.html), internet explorer 8 does support table options for display property, but in this example it exhibits very strange behaviour
[http://jsfiddle.net/e3cUn/3/](http://jsfiddle.net/e3cUn/3/)
In a normal browser, inner image will be scaled to fit 150x150 box without changing dimension ratio (stretching).
But in IE8, outside box (blue one) will also stretch:
1) Have you seen anything like that? It seems to be related to `text-align:center`: removing this property fixes the problem, but I do need to center image (in non-ie browsers, at least).
2) If this can't be fixed properly, how can I provide a special `display` value for IE? I've seen a few examples on the web, like `#display: block;`, but all of them work up to IE7 only.
I know about `<!--[if IE 8]>` and similar commands to put in html, but I was actually looking for a way to do that in css file. Something like this
```
display: table-cell;
#display: block;
```
Second line isn't a comment, it overrides previous value for ie7 and below. (but not ie8)
Thanks!

4,608,317 | 1 | null | null | 4 | 1,070 | I'm writing a Fluent NHibernate mapping for a legacy Oracle database. The challenge is that the tables have composite primary keys. If I were at total freedom, I would redesign the relationships and auto-generate primary keys, but other applications must write to the same database and read from it, so I cannot do it.
These are the two tables I'll focus on:
## Example data
```
Trips table:
1, 10:00, 11:00 ...
1, 12:00, 15:00 ...
1, 16:00, 19:00 ...
2, 12:00, 13:00 ...
3, 9:00, 18:00 ...
Faults table:
1, 13:00 ...
1, 23:00 ...
2, 12:30 ...
```
In this case, vehicle 1 made three trips and has two faults. The first fault happened during the second trip, and the second fault happened while the vehicle was resting. Vehicle 2 had one trip, during which a fault happened.
## Constraints
Trips of the same vehicle never overlap. So the tables have an because every fault either happens during a trip or it doesn't. If I wanted to join them in SQL, I would write:
```
select ...
from Faults left outer join Trips
on Faults.VehicleId = Trips.VehicleId
and Faults.FaultTime between Trips.TripStartTime and Trips.TripEndTime
```
and then I'd get a dataset where (one-to-many as I said).
Note that there is no Vehicles table, and I don't need one. But I did create a view that contains all VehicleIds from both tables, so I can use it as a junction table.
## What am I actually looking for?
The tables are huge because they cover years of data, and every time I only need to fetch a range of a few hours.
So I need a mapping and a criteria that will run something like the following SQL underneath:
```
select ...
from Faults left outer join Trips
on Faults.VehicleId = Trips.VehicleId
and Faults.FaultTime between Trips.TripStartTime and Trips.TripEndTime
where Faults.FaultTime between :p0 and :p1
```
Do you have any ideas how to achieve it?
Currently the application shouldn't write to the database, so persistence is not a must, although if the mapping supports persistence, it may help at some point in the future.
I know it's a tough one, so if you give me a great answer, you will be properly rewarded :)
Thank you for reading this long question, and now I only hope for the best :)

4,608,867 | 1 | 4,609,992 | null | 2 | 2,236 | I've followed several tutorials and read official docs at code.google.com, but still didn't manage to resolve this thing.
I am creating simple service that'll check if user can be logged.
```
public interface LoginService extends RemoteService {
/**
* Checks, if user has valid login.
* @param user User's login.
* @return True if such a login is in the database.
*/
boolean isValidUser(User user);
}
```
And here is Async interface:
```
public interface LoginServiceAsync {
/**
* Checks, if user has valid login.
* @param user User's login.
* @param callback the callback to return True if such a login is in the database.
*/
void isValidUser(User user, AsyncCallback<Boolean> callback);
}
```
```
public class LoginServiceImpl extends RemoteServiceServlet implements LoginService {
/**
* serial version UID
*/
private static final long serialVersionUID = 1044980345057997696L;
/**{@inheritDoc} */
@Override
public boolean isValidUser(User user) {
boolean success = true; //TODO change
}
}
```
Now I have entry point class MailClient.java. I append here widget like:
`CustomWidgets.getLoginWidget(this); // access rootPanel and append widget`
Now I need to make actual call to my service,
```
LoginServiceAsync loginService = (LoginServiceAsync) GWT.create(LoginService.class);
User user = new User(boxName.getText(), boxPassword.getText());
AsyncCallback<Boolean> callback = new AsyncCallback<Boolean>() {
@Override
public void onFailure(Throwable caught) {
Window.alert(caught.getMessage()); //TODO change
}
@Override
public void onSuccess(Boolean result) {
Window.alert("success"); //TODO change
}
};
((ServiceDefTarget) loginService).setServiceEntryPoint(GWT.getModuleBaseURL()+"login"); // dunno what should be here
```
So to recap, .

```

The problem is that there is something that im doing wrong, i use this simple line: mydinamictext.htmlText = htmlText. But the result is a NON css formated text. Here is a screen capture, the one of top is with the textfield created in code, and the bottom one with my textfield:
So, how can i apply the css and the fonts to my dynamic textfield and not create a new one. THANKS ALOT!

4,611,291 | 1 | 4,615,793 | null | 7 | 1,648 | I recently wrote a native NT registry editor for Windows, and ran it on Windows 7. To my surprise, in addition to the two standard root keys, MACHINE and USER, that are present on Windows XP, there was also a mysterious key named "A", that cannot be opened in any way, whether by permission changes or backup privileges or otherwise:
Does anyone know what this key is for? I don't believe it's for any software, because it was there before I installed anything on the machine, and I believe I saw it on another fresh installation as well. It's rather very suspicious, and I'm curious as to why it's there. (If I'm curious enough, I might end up writing a driver to open it up without a privilege check, to see what happens!)
(I wasn't sure whether to put this on SuperUser or StackOverflow, since I think it could go in either one. I could be wrong, though; sorry if this isn't the appropriate place.)
Edit:
If forgot to say, I don't believe you can even see this key using the Win32 API, like `RegOpenKey` -- you have to use the native API like `NtEnumerateKey` instead.

I want to have a standard multi-select listbox that works normally. Unfortunately, the Windows Forms ListBox (with `SelectionMode.MultiExtended`) is not fully functional. The missing functionality is that it doesn’t let you select a disjoint set of items by using Ctrl+Arrow keys and Ctrl+Space. (Try it in Windows Explorer to see how it’s supposed to work.) I am trying to subclass ListBox and add this missing functionality. To this end, I intend to respond to Ctrl+Arrow keys in the `OnKeyDown` protected method, but in order to do so, I need to be able to move the outline without changing the set of selected items. How do I do that?

4,612,173 | 1 | 4,616,180 | null | 1 | 1,385 | I'm currently developing a script for a map in COD4. I think that the language is so simple that I'm tagging this as language-agnostic since the problem is in the algorithm for this situation.
There is a room which is 960 units wide. And inside it there's an object in the middle, which we'll count as the axis. The ball is supposed to move to a random position each time it is hit, but should not traverse further than the walls. Here's a diagram:
The API of the game only allows the moving of objects relative to its position, as far as I know, so here's code that I came up with. The problem is that it begins to produce unexpected results and this is crashing my head. Could somebody help me out?
```
while (1)
{
self waittill ("trigger", player); //Wait till player hits the object
head_origin thread head_move();
}
head_move()
{
/* level.prevx is a global variable which I use to store
the distance traveled in the previous shot. Defaults to 0 */
/*This works in the first and second hit, but then it begins to show
incorrect max and min values*/
x_min = (0-480) + level.prevx;
x_max = x_min + 960;
x_units = RandomIntRange( x_min, x_max ); //Create a random integrer
log2screen("MIN: " + x_min + " and MAX: " + x_max + " and MOVED " + x_units);
log2screen("Moved " + x_units);
//Movement function, first parameter is the distance to be traveled, and the second one is the speed
self movex (x_units , level.movespeed);
level.prevx = x_units;
}
```
Just to clarify. When the user shoots the ball, its position changes to a certain value. Now, if he hits it again, the min and max values of the random int generator should change to prevent the ball from moving outside the walls. Example:
1. Level starts. The ball is in the middle of the room. The min and max ranges are -480 and 480 respectively
2. The user hits the ball and its moved -200 units (200 units to the left).
3. Now, the min and max range should be -280 and 680.
I hope this is clear enough.
Edited the sign as FlipScript suggested. Here's the output from the log2screen functions, what is actually happening:
1. MIN: -480 and MAX 480. MOVED 67
2. MIN: -413 and MAX 547. MOVED 236
3. MIN: -244 and MAX 716. MOVED 461
Just a sample case. Something is backwards I believe, these aren't the right calculations to do.

4,614,327 | 1 | null | null | 1 | 1,084 | Consider the following image that shows the encryption hierarchy used in SQL Server. Please note the first blue block, that says the SMK is encrypted using [DPAPI](http://msdn.microsoft.com/en-us/library/ms995355.aspx). The DPAPI uses a currently logged-in user credentials (+ more) to encrypt data, so it's machine-specific. This means that SMK (as well as DMK and any derived password) will be machine-specific (actually it's generated by SQL Server's setup). OTOH, I can create/backup an X.509 certificate in SQL Server (using CREATE CERTIFICATE, BACKUP CERTIFICATE and so on).
I'm developing a Web App that needs to encrypt and store CC information in a database column. I need to access those data, later on another machine so the db backup should be actually readable when restored on another machine (albeit, for someone who has got access to the above-mentioned certificate).
I'm wondering how am I supposed to restore a backup on another machine when the SMK is specific to the current instance of SQL Server? What should I do to access those encrypted data once they are restored on another machine?
Correct me if I am wrong!
We could use the `BACKUP SERVICE MASTER KEY TO FILE` command to back the currently used SMK. This key, however, can be restored on any other SQLServer (on/out of the same machine) using the `RESTORE SERVICE MASTER KEY FROM FILE` command. When the SMK is restored, it's being encrypted once again using DPAPI so that can be stored somewhere on the machine.
Any help would be highly appreciated,

4,618,439 | 1 | null | null | 0 | 1,685 | I have a ListBox that specifies ItemContainerStyle. The ItemContainerStyle uses Triggers to set the ContentTemplate.
I would like to set the Visibility of a ContentControl (named "ExpanderContent") in the ContentTemplate when the template is applied. I'd prefer to use the value of an attached property set on the ListBoxItem, if possible.
Perhaps it will help make the question clearer to see this one example of what I've tried using a Style applied to the ContentControl (named "ExpanderContent"). I realize that the Style is not set on the ContentControl in the code below. I have set it and seen it applied and seen that there is no error regarding resolving the attached property.

The real world application of this nonsense is that I have a list box and the items in the list box have templates that change when selected. The templates have an expander and I'd like to leave the expander expanded even when the item is not selected. As it is now, whenever I change the list box selection, the content template is reapplied in its original state, which is collapsed - so I can never have more than one expanded at a time.

If it is, please clarify and I will be happy to merge.
I want to bind to a writable DataGridView using a linq-to-entities query containing a join. The model is as follows:
The denormalized DataGridView should be bound like so:
The following code binds but results in a readonly DataGridView because the linq-to-entities query returns an anonymous type ([see this post](https://stackoverflow.com/questions/2460599/binding-linq-to-entities-query-results-to-a-datagridview)). I'm at an impasse because I think I need the anonymous type to do the denormalization.
```
var query = from t in iDictionaryContext.DisplayTexts
from l in iDictionaryContext.Languages
where
t.LanguageID == l.LanguageID
select new
{
Key = t.DisplayKey,
Text = t.DisplayText1,
Language = l.LanguageName
};
```
I also tried the solution suggested [here](https://stackoverflow.com/questions/4065627/binding-datagridview-to-a-multiple-table-linq-to-sql-query) but it seems to apply to linq-to-sql but not to linq-to-entities. When setting the bindingsource.datasource to the linq-to-entities query, an exception is thrown reading "Only parameterless constructors and initializers are supported in LINQ to Entities."

Notice how the button is ripped apart? Only in Chrome and only when placed inside a paragraph. It gets even stranger: this only happens for the first button inside the paragraph, if I would place three buttons inside a paragraph, only the 1st one is screwed up.

I'd like to take it a step further however and actually draw a connection between the two columns.
I suppose a screen shot is the easiest way to explain what I'd like to accomplish.
It's important that both columns scroll independently of each other, yet the lines connecting the two highlighted sections should remain accurate and update as the columns are scrolled.
Is there a way to accomplish this without using Flash or HTML 5 canvas? Are there any ready made jQuery plugins to accomplish this?

Web apps have very similar thing, menu tabs (Logo, Questions, Tags, Users, Badges, ...).
However I cannot find equivalent of top level menu in Android framework. Assume that my app has 5 main activities. According to [menu design guidelines](http://developer.android.com/guide/practices/ui_guidelines/menu_design.html) options menu should contain actions related to current activity. So how an app should allow users to easily switch to one of five main activities.
It seems that different apps solve the problem in different ways. Some have a tab list at the top of the screen, some at the bottom. Even Google applications aren't consisted in that field. Google Listen has an options menu item called 'Listen Home', however Listen main activity has no that options menu item. Others have two icons in app luncher which start two different activities from one app.
I realize that due to small phone screens Android apps have to be designed in a slightly different way than web or desktop apps. But I have a feeling that the app top level menu topic was omitted in Android framework. And developers are on their own here. Or am I missing something?
Update: this is Google blueprint for a great app
Update2: this [an example app](http://code.google.com/p/iosched/) of these patterns
Update3: [GreenDroid](https://github.com/cyrilmottier/GreenDroid) library helps a lot implementing these patters in your apps. It seems that dashboard and action bar patterns are becoming quite popular.

I had to ensure that the size of the glow is the same as the normal marker image, so that the resulting `Drawable` doesn't rescale (marker image size is 32x37 px).
However, what I am aiming for is in fact a bigger glow (that would, indeed yield a bigger image), such as : 
How can I render a drawable which yields a bigger glow (thus using an image which is indeed bigger than the normal marker image) and does result in a scaled / resized normal marker ? Is that feasable ?

However, I am receiving some trouble from the compiler when trying to build it. I created a small helper library called `ExtensionMethods`, compiled it, dropped the .dll in the `bin` folder of the outlying project, and added a reference to it in the newly-converted library. The library has two namespaces, `ExtensionMethods.Json` and `ExtensionMethods.Enums`. In any class where I want to use the `Enums` namespace, I import it with `using ExtensionMethods.Enums`. I do the same for the `.Json` namespace (which works fine, by the way).
The following is picture evidence of what is happening:
Notice the blue squiggle under `Enums` with a simultaneous suggestion for `Enums` from Intellisense. Here is proof that VS actually recognizes the assembly (`.ToInt()` is the name of the extension method):
Notice how `.ToInt()` is both suggested by Intellisense as an extension method AND does not have a squiggle under it, even though ALLEGEDLY...
(three files use this namespace)
which would make sense, except for...
Essentially, what this is saying is that, "Yes, Jason, you have referenced all your assemblies correctly, yes, your assemblies contain the namespaces they should, but no, I don't feel like compiling today."
I just want to compile and be done with this monster. What am I missing here?
`ExtensionMethods.Json`, another namespace in `ExtensionMethods` works fine when referenced and does not produce an assembly reference error. Both projects were created on the same 64-Bit machine and everything targets .NET 4.

When I check to see the the data is retrieved when I iterate through either the Java `Hashtable` or the .NET `Hashtable` (via an `Enumerator`), each one consistently has the same data, in the same order ... but has a different order.
Is there any way I can make it so that the .NET `Hashtable` data is in the same order as the Java `Hashtable`?
I understand that `Hashtable` do not handling ordering - so I feel like there's nothing that can be done. I also cannot change the datatype in the Java code from .. say .. a `Hashtable` to something else.
Here's some same data to illustrate my situation.
### Data, added sequential for either code base :-
1. num | someData
2. pagenum | someData
3. x | someData
4. top | someData
### Java Code:
```
private Hashtable identifiers = new Hashtable();
...
identifiers.put(symbol, identifier);
```
### Java output via iteration over an enumerator:
### .NET code:
```
private Hashtable Identifiers = new Hashtable();
...
Identifiers.Add(symbol, identifier);
```
### .NET output via iteration over an enumerator.
Any ideas or suggestions?

4,621,364 | 1 | 4,621,783 | null | 1 | 597 | I recently created a new Ruby on Rails 3 application locally on a Mac OS, named "test".
Since I use apache2, in the private/etc/apache2/ I set the VirtualHost for the "test" application:
```
<VirtualHost *:443>
ServerName test.pjtmain.localhost:443
DocumentRoot "/Users/<my_user_name>/Sites/test/public"
RackEnv development
<Directory "/Users/<my_user_name>/Sites/test/public">
Order allow,deny
Allow from all
</Directory>
# SSL Configuration
SSLEngine on
...
</VirtualHost>
<VirtualHost *:80>
ServerName test.pjtmain.localhost
DocumentRoot "/Users/<my_user_name>/Sites/test/public"
RackEnv development
<Directory "/Users/<my_user_name>/Sites/test/public">
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
```
Of course I restart apache2, but trying to access to `http://test.pjtmain.localhost/` I have this error message from:
FIREFOX
```
Oops! Firefox could not find test.pjtmain.localhost

Safari can’t open the page “http://test.pjtmain.localhost/” because Safari can’t find the server “test.pjtmain.localhost”.
```

I did a with the following result:
```

4,621,592 | 1 | 4,621,666 | null | 3 | 183 | Please take a look at this example -
I know I'm using the `footer/nav` correctly but the `<side>` and `<section>` is kinda confusing.
The `<figure>` will be just one huge logo. Beside that will be the main content. Would `<aside>` be proper use? Its not side content like a sidebar so thats why i'm asking.
Also the `<section>` would be columns for the content, would that be right?

Database is UTF-8 encoding

What I'm receiving when the file is imported is.
But in the CSV file everything looks clean, and the actual number is +1 (250) 862-8350
So I don't know what the issue is, my hunch is something to do with a form of trimming but I haven't been able to figure out what it is... any light would be appreciated!

## I was unsuccessful browsing web for a solution for the following simple question:
How to draw 3D polygon (say a filled rectangle or triangle) using vertices values?
I have tried many ideas but all failed, see:
```
from mpl_toolkits.mplot3d import Axes3D
from matplotlib.collections import PolyCollection
import matplotlib.pyplot as plt
fig = plt.figure()
ax = Axes3D(fig)
x = [0,1,1,0]
y = [0,0,1,1]
z = [0,1,0,1]
verts = [zip(x, y,z)]
ax.add_collection3d(PolyCollection(verts),zs=z)
plt.show()
```
I appreciate in advance any idea/comment.
```
import mpl_toolkits.mplot3d as a3
import matplotlib.colors as colors
import pylab as pl
import numpy as np
ax = a3.Axes3D(pl.figure())
for i in range(10000):
vtx = np.random.rand(3,3)
tri = a3.art3d.Poly3DCollection([vtx])
tri.set_color(colors.rgb2hex(np.random.rand(3)))
tri.set_edgecolor('k')
ax.add_collection3d(tri)
pl.show()
```

4,622,096 | 1 | 4,622,385 | null | 6 | 8,386 | I try to fetch user's feeds via graph api from my Android application. It generally works but some feeds that I can see on the wall are missing in the json response.
I call the url [http://graph.facebook.com/someUserId/feed](http://graph.facebook.com/someUserId/feed), by using the Android Facebook SDK methods, so the access token should be provided automatically, but it's not really relevant I think in my case. Nevertheless fyi, the user of my app is authenticated via OAuth.
I already checked the following:
- - - - [http://graph.facebook.com/someUserId/feed](http://graph.facebook.com/someUserId/feed)
This is an example of the problem - since all my posts are public, I can just call the json url directly in a browser to do a test.
I want to get wall feeds from user:
[http://www.facebook.com/mathias.lin](http://www.facebook.com/mathias.lin)
Screenshot1: note the 3 marked postings, all posted by myself
and here the json response, as you can see, the 1st and 3rd wall posts are included in the json, but the 2nd post is not. Why?
The related json url is:
[http://graph.facebook.com/mathias.lin/feed](http://graph.facebook.com/mathias.lin/feed)
I am getting the 'missing' feed when I add an access_token to the url - but why? The posted feed has a privacy setting for 'everyone'?!
This is the missing feed that I get when using the access_token:
