[Cannot connect to UserPC\SQLExpress](https://stackoverflow.com/questions/4638222/cannot-connect-to-userpc-sqlexpress)
I have been struggling to find a solution for this from long but in vain. I recently installed SQL Server Management Studio Express and tried to login with SQL authentication with 'sa' username. It was giving me error 233, so I enabled NamedPipes, Shared Memory and TCP IP from Configuration Manager.
Now, I when I try to login, it shows an Error:

4,640,588 | 1 | null | null | 27 | 39,447 | I am doing a lot of researching lately about how to get a different looking with nice effects `UITabBar` on my iPhone app, but unfortunately I am only finding things on how to replace background color etc.
Well, I've checked out this app called [Momento](http://www.momentoapp.com/) which is pretty cool and presents a very slick tabBar:
So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :)
- as you can see this app has this animated arrow that runs above the selected item with a very smooth animation.- is not that blue- default one neither the default state which displays in a different shade of brown and gray version.- with beveled vertical lines.- for the tabBar- for the tabBar
At this point after some research I am able to set the height and background image by subclassing `UITabBarController` but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect.
How do I do this? Please clarify what can or can't be done by subclassing the `UITabBarController` and specially if can be done in Interface Builder.

I've got a pretty simple Backtrace for the evaluation of my function, but I cann't seem to work out how to use it to find out in which Lisp 'form' in my function the exception occurred.
I'd appreciate any clues as to what I should be doing, to find where in my code the error originated.
Also - why does the second frame display as "no debug information available for frame"?
I've attached a screen shot with the debugger, and repl (I've also included my function below - I know it's very wrong - but I'm just interested in learning to use the debugger properly). In addition, I hit 'v' on the first frame to go to the source, but this resulted in the error below the repl.

4,642,010 | 1 | 4,642,192 | null | 1 | 931 | I have a problem that seem unsolvable, due to HTML limitations.
Here is a capture that may explain you the whole thing:
### #
As you can see, I want a transparent part to move above the mouseovered menu item.
But as I am thinking that, I find out that this won't work cause the menu item will loose the :hover stat as soon as the transparent part will arrive below the mouse.
If where were with actionscript3, this would be easily done by setting the .mouseEnabled property on my transparent part, so that it isn't considered by the mouse.
Do you know if something similar is possible with html? Do you have other solutions/track to follow, to success what I wanted to do?

Very basic example ( image paths changed ) but works. [http://www.jsfiddle.net/QZuA5/](http://www.jsfiddle.net/QZuA5/)
Essentially its the preview div, I want to create. We can place logo dynamically using absolute positioning.
So essentially its the js to create the div placeholder bg colour and font text colour, that will parse valuse when we submit the form.

The only problem is that when you type the 1st character in the input field, it will display all term suggestions, including terms which don't contain this character.
And only after you type the 2nd character it will behave normally, displaying tag suggestions containing only those 2 characters.

Suppose I have an application a search for all gas stations within 10 mile radius of a certain location. However one side of this location is surrounded by a mountain range that you have to drive 50 miles to get around. You would not want to return results from the other side of the mountain. What are some good algorithms/techniques to deal with such a problem? I know with point to point searches you can use path costs but I am not sure what the technique is with radius searches.
Here is an example:
The red line is a chord on the radius circle from 40,-74 to 41,-72 lat long (not accurate just saying) The user at 40,-73 performs a geographic radius search for something which also encompasses areas across the LI sound in Connecticut which are impractical to get to. The algorithm should know that there exists a chord completely intersecting the search circle and not return results that are on the other side of that chord. So only points in the green area would get returned.
This should be able to be done without any road network analysis if the programmer defines these bounding lines. For instance there may be an area in some country that is dangerous to pass through and you would want people on either side of that area to be restricted to that side. Or an international border etc. I am just asking this because I am pretty sure people are doing this.

4,645,229 | 1 | 4,646,638 | null | 1 | 2,492 | Morning folks,
I have a temporary table with 135,000 rows and 24 columns, of those rows I need to insert about 8,000 of them into an 8 column table. If run my insert the first time round (i.e. when my 8 column table is empty) it runs in about 6 seconds. When I run the same query again (this time round it shouldn't insert anything as the rows have already been inserted) it takes 30 minutes!!

4,645,329 | 1 | 4,645,616 | null | 0 | 3,891 | I'm using CSS3PIE to apply some rounded corners to elements in Internet Explorer that will get them by stylesheet in other browsers. I've run into some issues with it though.
In IE8, I discovered that any element that had the PIE behaviour would behave strangely. The container would jump a few pixels to the right, but the content would stay in its original position, giving the appearance that the content had all shifted left relative to its container. This would be especially problematic on elements with no or small amounts of padding.
I was able to hack my way around the problem in IE8 by using X-UA-Compatible, but I'd rather avoid this solution if at all possible. I don't have access to IE9 for testing but my understanding hacks like PIE aren't necessary and it would be wasteful to force a compatibility mode in a browser that doesn't need it.
I have worse issues in IE6, with the PIE layout breaking down completely on a list that is set up to use `display:inline; zoom:1;` list items (to simulate inline-block, which works in IE8 and the other browsers). Here the borders of the list items get rendered in completely the wrong place.
So ideally, I'd like to have PIE work properly in IE6, and in IE8 without having to resort to compatibility mode. As far as IE6 goes, a graceful fallback where PIE is just not applied will do. IE7 is the only browser where the page displays as intended.
I can't provide an example page just at the moment unfortunately, I can add one later though.
Here are some screen grabs made with IE Tester. I'm hoping they will make things a little more clear for everybody. As you can see, IE7 is fine. However, in IE8, the containers are offset to the left relative to their content, and in IE6 the list elements (with the rounded 1 pixel border) are a complete mess!
Full size versions for [IE8](http://www.thiscanthappen.com/temp/so/ie8.png), [IE7](http://www.thiscanthappen.com/temp/so/ie7.png) and [IE6](http://www.thiscanthappen.com/temp/so/ie6.png) are also available
Here's a link to a demo page.
As other designers are working on the stylesheets and other parts of the design I can't promise it will remain fully reflective for very long, but hopefully it will for long enough to solve the problem. (Yes, I'm aware there's JS errors in IE6, those aren't my problem).

```

{

4,646,063 | 1 | 4,648,412 | null | 1 | 1,582 | So here's my image:
The problem is, draw9patch can't create normal 9 patch from this (shows errors in padding). Neither does android scale it correctly if I create 9 patch manually, like so:
I believe that it's a color issue, that android sees the borders of my original image as a part of 9 patch paddings and thus, scales incorrectly.
Is there a way, to create a 9 patch from this?
Thanks in advance :)
There must be NO extra empty border around original image, or it will persist and will have a white lines around it.
There must be 1 extra pixel added to every side of the raw image to contain 9 patch paddings, so if the original width was 50px, it will be now 52 px.
It's not the first time I'm making a nine patch< just this time it doesn't work.
If you don't believe me, try and do it in draw9patch.bat and you'll see that it doesn't add extra border at the top and shows error even on the original image.
Ok. NVM, just had to make raw image a bit wider. Now it scales right,

4,646,340 | 1 | null | null | 20 | 25,464 | I’m trying to implement an order entry form using ASP.NET MVC but facing a lot of difficulties. All the samples that I found are related to viewing master detail forms, and none for adding or editing.
Suppose I have two tables: Order and OrderLines that are related to each others with one-to-many relationship. In the main view I had a “New” button when clicked it should show a new order view composed of the order fields, a grid that shows the order lines, and a “Save” button that when clicked will persist the whole order along with its lines into a database. The grid should have three buttons: “Add Line”, “Edit Line”, and “Delete Line”. When the “Add Line” is clicked a new view should be shown that allows the user to add the line to the order view grid lines –at this stage the database is not affected-. When the user clicks “Edit Line” a view will be shown that allows the user to edit the selected line and when done update the order grid lines.
The most difficult problems are:
How to pass the order and its lines collection between the order view and the order line views?
How to update the order view based on changes in the order line view?
And how to persist changes between views without the database being involved?
Is there a concrete example that shows how to implement this using MVC?
Your help and feedback is appreciated.

4,646,745 | 1 | 4,647,170 | null | 0 | 604 | I am absolutely totally news to Rails and to MongoDB. I have been following tutorials from a good book and create my first Rails app with a light Twitter copy. Everything went fine and smooth.
But as part of my learning process I wanted to build the same app using MongoDB rather than the default SGBD.
I therefore configured mongo and installed the mongo_mapper gem. Everything has been configured properly following this tutorial: [http://www.mongodb.org/display/DOCS/Rails+3+-+Getting+Started](http://www.mongodb.org/display/DOCS/Rails+3+-+Getting+Started). Then I struggled a little bit to allow Rails generate to work without throwing me the --orm not specified error. In order to get past this I had to add the rails3-generators gem and add it to the Gemfile.
Once all this was done, everything worked fine. I was able to successfully launch the Rails server.
I added a User controller thanks to the generate. The page works fine and even lists the users I have previously added:
However all the other actions, showing, editing, deleting, etc. are not working (creating works, but then it goes to show and the errors comes):
It's virtually the same error for all different actions.
The one difference I can notice right off the bat is that with the non MongoDB db, the id's of the user was starting at 1, etc. but here with MongoDB it looks like a randomly generated id that is much more complex and that is not of type int: 4d2ae91d4403baa84a000002
I am thinking that this may be creating the issues, since all action are using the id as a parameter... but I have no idea how to fix this. I have looked at the ruby generated code and it looks alright to me (extremely similar to the code generate for the default db).
Any help would be greatly appreciated ! I don't know how to go forward with my project without solving a simple generate code with mongodb.
Thanks,
Alex
ps:
please that I did not write any of this code at all. everything has been generated, which is kinda why I expected to work from the get go...
as asked here is the code for users_controllers:
```

@users = User.all
respond_to do |format|

4,647,747 | 1 | 4,647,788 | null | 11 | 2,899 | I'm adding a map next to a form on my web page. The idea is that people can sign up, and when they type in their address and click search, it place-marks their house, they must do this before they submit the form (geolocation has a large role on my site).
Unfortunately, I have added the map, but within the map window the map itself appears to be offset. See the image below to illustrate what I mean:
I can only drag the map from within the "mapped" part of the box. If I select the grey area to drag the map around, it fails.
Any ideas what could cause this?

mapTypeId: google.maps.MapTypeId.ROADMAP
}

I am using the following data (The left side are values I enter for the data to be based upon, the right side is the results of the generated data):
As you can see, the % Diff is very good for Avg Click, but Click/Time is off when there is a high Day StdDev (Day +/-). The difference when there is a low Day Stddev is close to 0.
I think this is because the var becomes inaccurate because the (Which is used indirectly to determine the running avg) is "guessed" at the start, and needs to be reassessed each click because the high StdDev adds randomness and the original "guess" becomes more and more inaccurate.
I am not sure if this is the problem, or if it is how I can even solve it.
I am just looking for advice on the best way to do what it is I want. I am not sure why the stdDev are so far off either, but thats not a big deal. I'd rather have a more accurate Click/Time than anything else- reguardless what the Day StdDev is.

4,647,791 | 1 | 4,650,195 | null | 4 | 11,278 | I'm trying to use LibTiff in a C++ Program in Visual Studio 2010. I downloaded tiff-3.9.2.zip from [ftp://ftp.remotesensing.org/pub/libtiff](ftp://ftp.remotesensing.org/pub/libtiff). To test LibTiff it would be nice if someone could give me a step by step instruction how to import libtiff to visual Studio and build the Fax2Tiff tool.
There are so many files so that I am totally confused.
What I already have done:
1) Created a new Empty Win32 Console Application Project named "TiffTest"
2) Copied the folder "libtiff" from the tiff-3.9.2.zip to the Project Folder
3) Copied the file "fax2tiff.c" to the Project Folder
4) Added those files to the Project
5) Added the "libtiff" folter to the additional include folders
6) Renamed the files "tif_config.vc.h" and "tiffconf.vc.h" to "tif_config.h" and "tiffconf.h"
7) Tried to compile it.
This does not really work. All I do to get rid of the error messages causes new error messages. Can anyone tell me how I can get libtiff to work?
I really need help...
Thank you so much!

If it's not possible could you give me a clue to make the Y Axe always visible.
Edit: May I do this by drawing an other chart an displaying only the axes of the second graph and no datas on it?

Do you think this schema markup looks okay?
Doctrine schema.yml:
```

```
When I a new reply is made,i'll make sure the boolean for "recipient_read" for each recipient is set to false and of course i'll make sure sender_read is set to false too.
I'm using a hash for the URL: [http://example.com/user/messages/aadeb18f8bdaea49882ec4d2a8a3c062](http://example.com/user/messages/aadeb18f8bdaea49882ec4d2a8a3c062)
(As the id will be starting from 1, i don't wish to have [http://example.com/user/messages/1](http://example.com/user/messages/1). Yeah, I could start incrementing from a bigger number, but i'd prefer to start at 1.)
Is this a good way to go about it? Your thoughts and suggestions would be hugely appreciated.

For example, DarkGray is actually lighter then Gray ? Also, I can't see any logic in the gradation of rgb values, it goes from 0 to 105 to 128 ?
```

105 : DimGray

What I want is a GrayScaleBrushes class which behaves exactly like the Brushes class, but with my custom scheme, like :
```
GrayScaleBrushes.Pct05
GrayScaleBrushes.Pct10
GrayScaleBrushes.Pct15
..all the way to.Pct95
...
ie: e.FillRectangle( GrayScaleBrushes.Pct05, exampleRect );
```
How to do that, making sure that the brushes will dispose correctly ?
The .NET Brushes class looks like the following (disassembled using reflector ).
```
public sealed class Brushes
{
// Fields
private static readonly object AliceBlueKey = new object();
// Methods
private Brushes()
{
}
// Properties
public static Brush AliceBlue
{
get
{
Brush brush = (Brush) SafeNativeMethods.Gdip.ThreadData[AliceBlueKey];
if (brush == null)
{
brush = new SolidBrush(Color.AliceBlue);
SafeNativeMethods.Gdip.ThreadData[AliceBlueKey] = brush;
}
return brush;
}
}
}
```
SafeNativeMethods seems unaccessible to me. Suppose I just returned a SolidBrush in a static method, would that make everything dispose correctly ? (And how to test that?)
```
public sealed class GrayScaleBrushes
{
private static SolidBrush pct05 = null;
public static SolidBrush Pct05
{
get
{
if (pct05 == null)
{
int rgbVal = GetRgbValFromPct( 5 );
pct05 = new SolidBrush(Color.FromArgb(rgbVal, rgbVal, rgbVal));
}
return pct05;
}
}
private static int GetRgbValFromPct(int pct)
{
return 255 - (int)(((float)pct / 100f) * 255f);
}
}

4,650,984 | 1 | 4,651,044 | null | 4 | 2,439 | I'm running through a few tutorials that describe ways of applying custom images to UIButtons in iPhone programming using Obj-C.
One method i like is to place a UIButton (Round Rect Button) on a XIB using Interface Builder then in the 'viewDidLoad' method of the XIB's view controller skin the button thus:
```
UIImage *ButtonImageNormal = [UIImage imageNamed:@"button_blue.png"];
UIImage *StretchableButtonImageNormal = [ButtonImageNormal stretchableImageWithLeftCapWidth:24 topCapHeight:24];
[self.Button setBackgroundImage:StretchableButtonImageNormal forState:UIControlStateNormal];
UIImage *ButtonImagePressed = [UIImage imageNamed:@"button_orange.png"];
UIImage *StretchableButtonImagePressed = [ButtonImagePressed stretchableImageWithLeftCapWidth:24 topCapHeight:24];
[self.Button setBackgroundImage:StretchableButtonImagePressed forState:UIControlStateHighlighted];
```
The trouble with this method is that the button doesn't lose its 'Round Rect' background and at the side of the buttons you can still see the white of the 'Round Rect' button peeping through past the custom images.
If however, i create a custom button from scratch using this code:
```
UIButton *CustomButton = [UIButton buttonWithType:UIButtonTypeCustom];
[CustomButton setFrame:CGRectMake(20, 100, 280, 45)];
[CustomButton.titleLabel setFont:[UIFont boldSystemFontOfSize:15]];
[CustomButton setTitle:@"Custom Button" forState:UIControlStateNormal];
[CustomButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[CustomButton setBackgroundImage:[UIImage imageNamed:@"button_blue.png"] forState:UIControlStateNormal];
[CustomButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
[CustomButton setBackgroundImage:[UIImage imageNamed:@"button_orange.png"] forState:UIControlStateHighlighted];
[self.view addSubview:CustomButton];
```
There is no such white background peeping through.
I really would like to use the 'Round Rect' method of placing and skinning buttons because i'd like to see their positions in Interface builder. Is there a method i need to use or a property i need to amend to get rid of the white background of a 'Round Rect' button in code.
Here's an image showing the problem:

I have a successful call to `glTexImage2D` like this:
`glTexImage2D(GL_TEXTURE_2D, 0, texture->format, texture->widthTexture, texture->heightTexture, 0, texture->format, texture->type, texture->data);`
I would like create an image (preferably a `CGImage` or `UIImage`) using the variables passed to `glTexImage2D`, but don't know if it's possible.
I need to create many sequential images(many of them per second) from an OpenGL view and save them for later use.
Should i be able to create a `CGImage` or `UIImage` using the variables i use in `glTexImage2D`?
If i should be able to, how should i do it?
If not, why can't i and what do you suggest for my task of saving/capturing the contents of my opengl view many times per second?
edit: i have already successfully captured images using some techniques provided by apple with `glReadPixels`, etc etc. i want something faster so i can get more images per second.
edit: after reviewing and adding the code from Thomson, here is the resulting image:
the image very slightly resembles what the image should look like, except duplicated ~5 times horizontally and with some random black space underneath.
note: the video(each frame) data is coming over an ad-hoc network connection to the iPhone. i believe the camera is shooting over each frame with the YCbCr color space
edit: further reviewing Thomson's code
I have copied your new code into my project and got a different image as result:
width: 320
height: 240
i am not sure how to find the number of bytes in texture-> data. it is a void pointer.

4,653,018 | 1 | 4,822,981 | null | 6 | 7,061 | I'm using iText in Java to select a few pages out of a big PDF document and save as a new, smaller PDF. At the same time I'd like to change their colours.
For example, suppose my pages all use shades of grey, and I'd like to make it green. All the colours used are shades of gray. I'd like to replace each of those colours with a corresponding colour in green.
---
> What exactly are you trying to accomplish?
Turn this... into this:
I have [some documents](http://charactersheets.minotaur.cc/), on which I'm already using iText to select a smaller set of pages from the document based on user input - cutting more than 100 pages down to about 5. At the same time I wish to produce green, blue, yellow, pink etc versions of them. Not every page is in grayscale, but all the ones that matter are, so I can force their colour space if need be.
---
Following Mark Storer's suggestion of blending modes, here's what I have:
```
val reader = new PdfReader(file.toURL)
val document = new Document
val writer = PdfWriter.getInstance(document, outputStream)
document.open()
/* draw a white background behind the page, so the
blend always has something to transform, otherwise
it just fills. */
val canvas = writer.getDirectContent
canvas.setColorFill(new CMYKColor(0.0f, 0.0f, 0.0f, 0.0f))
canvas.rectangle(10f, 0f, 100f, 100f)
canvas.fill
/* Put the imported page on top of that */
val page = writer.getImportedPage(reader, 1)
canvas.addTemplate(page, 0, 0)
/* Fill a box with colour and a blending mode */
canvas.setColorFill(new CMYKColor(0.6f,0.1f,0.0f,0.5f))
val gstate = new PdfGState
gstate.setBlendMode(PdfGState.BM_SCREEN)
canvas.setGState(gstate)
canvas.rectangle(0f, 0f, 100f, 100f)
canvas.fill
document.close()
```
(It's in Scala, but the iText library is just the same as in Java)
The problem is, all the blending modes iText has available are "separable" modes: they operate on each colour channel independently. That means I can separately adjust the cyan, magenta, yellow or black values, but I can't turn gray into green.
To do that, I'd need to use the Color blending mode, which is "non-separable", ie the colour channels affect each other. As far as I can tell, iText doesn't offer that - none of the non-separale blending modes are listed among the constants in `PdfGState`. I'm using iText 5.0.5, which is the latest version as of writing this.
Is there a way of accessing these blending modes in iText, or even of hacking them in? Is there another way of achieving the result?
- [This adobe document described blending modes](http://www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/pdf_reference_archives/blend_modes.pdf)
---
Even setting the blend mode to Color didn't work. I did this in code to force it:
```
val gstate = new PdfGState
gstate.put(PdfName.BM, new PdfName("Color"))
canvas.setGState(gstate)
```
and I checked the resulting PDF in a text editor to make sure it said the right thing. Sadly the result on screen just didn't work. I've no idea why, according to the PDF specification that should be the right blend mode.
---
> "Color" didn't work? Funky. Can we see the PDF?
[Here's a PDF](http://www.basingstokeanimesociety.com/sadie/blending-test.pdf).
Putting it on the web, I can now see that the "Color" mode works correctly in Chrome, but doesn't work in Acrobat 9 Pro (CS4). So the technique is correct, but Adobe fails at rendering!
I wonder if there isn't some way of "flattening" the effect of the blending mode, so the PDF contains the desired colour object directly rather than a blending intended to result in the right colour.
> Idea: Turn this upside down. Use the existing page as an alpha channel on a page filled
entirely with the desired color rather than the other way around.
How? I'm not sure the GState applies to adding a template?
Also, the imported page would need the white background adding first, or it will simply flood with colour wherever there isn't an object rather then blending.
I tried doing this:
```
val canvas = writer.getDirectContent
canvas.setColorFill(new CMYKColor(0.6f,0.1f,0.0f,0.0f))
canvas.rectangle(10f, 0f, 500f, 500f)
canvas.fill
val template = canvas.createTemplate(500f, 500f)
template.setColorFill(new CMYKColor(0f, 0f, 0f, 0f))
template.rectangle(0f, 0f, 500f, 500f)
template.fill
val page = writer.getImportedPage(reader, 1)
template.addTemplate(page, 0, 0)
val gstate = new PdfGState
gstate.put(PdfName.BM, new PdfName("Color"))
canvas.setGState(gstate)
canvas.addTemplate(template, 0, 0)
```
And [here's the PDF it produced](http://www.basingstokeanimesociety.com/sadie/blending-test2.pdf). Not quite right, either in Chrome or Acrobat :)
: Silly me. I changed the mode to "Luminosity", [producing this file](http://www.basingstokeanimesociety.com/sadie/blending-test2.pdf). As before, this looks correct in Chrome but not in Acrobat.
---
I just checked, and even Adobe Reader X doesn't render it properly. Which probably means what I'm asking for is impossible. :(
---
Leonard Rosenthal from Adobe got back to me, and clarified the problem: the "Color" blend mode only works when the transformation space is RGB, not CMYK. My PDF wasn't specifying the space, so Adobe products default to CMYK, while others default to RGB.
The solution in iText was to add this line near the top:
```
writer.setRgbTransparencyBlending(true)
```
Of course, for the sake of colour accuracy you don't want any more colour space conversions than absolutely necessary, so only use this line if you really do need to use RGB blend modes.
The colour pages produced look a little strange from a Photoshop user's perspective: it looks like light greys have been made more saturate than dark greys. I'm investigating ways of combining filters to adjust that output.
[Here's the result!](http://charactersheets.minotaur.cc/)
Many thanks to Mark Storer for helping me reach this solution.

4,653,513 | 1 | 4,653,631 | null | 3 | 3,983 | This question is messy, i dont need a working solution, i need some psuedo code.
How would i solve this maze? This is a homework question. I have to get from point green to red. At every fork i need to 'spawn a thread' and go that direction. I need to figure out how to get to red but i am unsure how to avoid paths i already have taken (finishing with any path is ok, i am just not allowed to go in circles).
Heres an example of my problem, i start by moving down and i see a fork so one goes right and one goes down (or this thread can take it, it doesnt matter). Now lets ignore the rest of the forks and say the one going right hits the wall, goes down, hits the wall and goes left, then goes up. The other thread goes down, hits the wall then goes all the way right. The bottom path has been taken twice, by starting at different sides.
How do i mark this path has been taken? Do i need a lock? Is this the only way? Is there a lockless solution?
Implementation wise i was thinking i could have the maze something like this. I dont like the solution because there is a LOT of locking (assuming i lock before each read and write of the haveTraverse member). I dont need to use the MazeSegment class below, i just wrote it up as an example. I am allowed to construct the maze however i want. I was thinking maybe the solution requires no connecting paths and thats hassling me. Maybe i could split the map up instead of using the format below (which is easy to read and understand). But if i knew how to split it up i would know how to walk it thus the problem.
How do i walk this maze efficiently?
The only hint i receive was dont try to conserve memory by reusing it, make copies. However that was related to a problem with ordering a list and i dont think the hint was a hint for this.
```
class MazeSegment
{
enum Direction { up, down, left, right}
List<Pair<Direction, MazeSegment*>> ConnectingPaths;
int line_length;
bool haveTraverse;
}
MazeSegment root;
class MazeSegment
{
enum Direction { up, down, left, right}
List<Pair<Direction, MazeSegment*>> ConnectingPaths;
bool haveTraverse;
}
void WalkPath(MazeSegment segment)
{
if(segment.haveTraverse) return;
segment.haveTraverse = true;
foreach(var v in segment)
{
if(v.haveTraverse == false)
spawn_thread(v);
}
}
WalkPath(root);

4,654,351 | 1 | 4,655,047 | null | 3 | 1,531 | I currently would like to expand my knowledge on Spring MVC so I am investigating the sample web apps that the spring distribution has. I am basically checking the Petclinic application.
In the GET method, the Pet object was added into the model attributes so the JSP can access the javabean properties. I think I understand this one.
```
@Controller
@RequestMapping("/addPet.do")
@SessionAttributes("pet")
public class AddPetForm {
@RequestMapping(method = RequestMethod.GET)
public String setupForm(@RequestParam("ownerId") int ownerId, Model model) {
Owner owner = this.clinic.loadOwner(ownerId);
Pet pet = new Pet();
owner.addPet(pet);
model.addAttribute("pet", pet);
return "petForm";
}
@RequestMapping(method = RequestMethod.POST)
public String processSubmit(@ModelAttribute("pet") Pet pet, BindingResult result, SessionStatus status) {
new PetValidator().validate(pet, result);
if (result.hasErrors()) {
return "petForm";
}
else {
this.clinic.storePet(pet);
status.setComplete();
return "redirect:owner.do?ownerId=" + pet.getOwner().getId();
}
}
}
```
But the thing that I cannot understand is during the POST operation. I look up at my firebug, and I notice that my post data are only the data that was entered by the user which to me is fine.
But when I inspect the data on my controller. The owner info is still complete. I look up at the generated HTML from the JSP but I cannot see some hidden information about the Owner object. I am quite not sure where does Spring gather the info on the owner object.
Does this mean that Spring is caching the model objects per each thread request?
This is for Spring MVC 2.5.

4,655,262 | 1 | 4,655,306 | null | 0 | 2,580 | I'm trying to compute a value from 2 given values quantity and price. I used the keyup event in jquery to compute the total from the current value of the qty and price.
How will I be able to reference the current textbox which initiates the keypress event. And put the corresponding total to the assigned box.
Do you know of any jquery plugins that will make it easier for me to achieve the result.
```
<script type="text/javascript">
$(function(){
$('input[name^=qty]').keyup(function(){
var curprice=$('input[name^=price]').val();
var curqty=$('input[name^=qty]').val();
var curtotal=curprice * curqty;
$('input[name^=comp]').val(curtotal);
});
});
</script>
</head>
<body>
<?php
for($a=0;$a<=5;$a++){
?>
Price:<input type="text" name="<?php echo 'price'.$a; ?>" value="<?php echo $a; ?>"/>
Quantity:<input type="text" name="<?php echo 'qty'.$a; ?>" value="<?php echo $a; ?>"/>
Computed:<input type="text" id="<?php echo 'a'.$a; ?>" name="<?php echo 'comp'.$a ?>" value="" />
<?php
echo "<br/>";
}

So I finally took some time off today to explore a little Rx.
Heres what I did:
Here's the only piece of running code:
```
private void button1_Click(object sender, EventArgs e)
{
var txtc = Observable.FromEvent<EventArgs>(textBox1, "TextChanged")
.Throttle(TimeSpan.FromSeconds(0.5))
.SubscribeOnDispatcher();//**also tried .SubscribeOn(this)
var t = from x in txtc select textBox1.Text;
t.Subscribe(x => listBox1.Items.Add(x));
}
```
Now, when run Debug (F5) I click the Button, all good, I then type something, poof! The form just silently dies!!
Note: I removed the code from the Form.Load event because of the known bug with VS not breaking on exceptions in that event on (and yes thats my machine)
This is what the debug output looks like:

What i am trying to achieve is:
When one of the inner groupboxes is collapsed, the outer groupbox and the window should shrink accordingly (currently the other non-collapsed groupboxes grow instead). But the user should still be able to resize the window, which should cause the groupboxes to grow accordingly:
I was toying around with `QWidget::setSizePolicy` and `QLayout::setSizeConstraint` of the different layouts/widgets, but havent come to a satisfying result yet..
Whats the best way to achieve this ? Can this be done without implementing your own size-hint functions ?

4,656,165 | 1 | 4,659,236 | null | 0 | 575 | I am currently experiencing a weird caching problem it would seem. When I load my data intially, I return all the data within given dates and my graph looks as follows:
Then I filter the data to return a subset of the original data for the same date range (not that it matters) and I get the following view of my data:
However, I intermittently get the following when I refresh the same filterd view of the data:
One can see that not all the data gets cached but only some of it i.e. for 12 Dec 2010 and 5 dec 2010(not shown here). I've looked at my queries and the correct data is getting pulled out. It is only on the presentation layer i.e. on Mainpage.xaml.cs that this erroneous data seems to exist.
I've stepped through the code and the data is corect through all the layers except on the presentation layer. Has anyone experienced this before? Is there some sort of caching going in the background that is keeping that data in the background as I've got browser caching off?
I am using the LoadOperation in the callback method within the Load method of the DomainContext if that helps...

I have applied Darin solution and it works very nice except for the image not being showed by the browser. This is the markup generated by the pager helper
```

<span class="paginationLeft">1-2 di 4</span>
<span class="paginationRight">
<span class="first"></span> |
<span class="previous"></span> |
<a href="/x/Hearing/HomeSummary?page=2">
<span class="next"></span>
</a> |
<a href="/x/Hearing/HomeSummary?page=2">
<span class="last"></span>
</a>
</span>
</div>
```
and these are the CSS rules defined
```
.pagination span.paginationRight span.first { width: 12px; height: 12px; background-image: url('../images/disabled-pager-first.png') }
.pagination span.paginationRight span.next { width: 12px; height: 12px; background-image: url('../images/disabled-pager-next.png') }
.pagination span.paginationRight span.last { width: 12px; height: 12px; background-image: url('../images/disabled-pager-last.png') }
.pagination span.paginationRight span.previous { width: 12px; height: 12px; background-image: url('../images/disabled-pager-previous.png') }
.pagination span.paginationRight a span.first { width: 12px; height: 12px; background-image: url('../images/pager-first.png') }
.pagination span.paginationRight a span.next { width: 12px; height: 12px; background-image: url('../images/pager-next.png') }
.pagination span.paginationRight a span.last { width: 12px; height: 12px; background-image: url('../images/pager-last.png') }
.pagination span.paginationRight a span.previous { width: 12px; height: 12px; background-image: url('../images/pager-previous.png') }
```
As you can see from the following images the correct CSS rules match the markup generated. Still I can't see images on the browser. Any idea?

I'm currently reading [MCTS Self-Paced Training Kit (Exam 70-433): Microsoft SQL Server 2008-Database Development](https://rads.stackoverflow.com/amzn/click/com/0735626391), where authors discuss the concept, but in a limited way.
From MSDN "[Understanding Pages and Extents](http://msdn.microsoft.com/en-us/library/ms190969.aspx)" I get an answer which doesn't really help. The web-page describes the size (8kb) of a page and how rows are stored in the page, and how columns will be moved automatically (by SQL Server) if the rows doesn't fit in the page.
But still, I wonder if the page-level is something I should pay attention to designing a database with ER-diagrams, tables and data types? Or, should I simply rely on that SQL Server handles pages automatically and in the best way possible?
Thanx for listening!

4,657,803 | 1 | null | null | 2 | 2,891 | I have got an application which create free sms alerts in one tab and show list of alerts on second tab. List of alerts is fetched from server once I click refresh button see image below.
What I want to do is that once I create alert in tab 1 then when I switch to tab 2, refresh button is automatically clicked or some technique which allow me to call particular function once tab is switched to 2nd tab. Each tab have separate Activity class and my refresh function is written in activity for 2nd tab.
