• Visual C# Number Combinations

  Ok. What I need is a method that discovers all the different combinations of any give set of numbers. For example, if my numbers were 1, 2, 3 all the possible combinations would be 123 132 213 231, ect. Can someone help Here is a simple, recursive solution (up to you to implement it): - If you're going to construct all the possible combinations of n characters, all you need to do: - Find all the possible combinations of n - 1 other characters, and prepend the n-th charachter to that result. Here's an example in php: function permutations ( $string ) { $results = array(); // only 1 letter -> only 1 permutation if ( strlen ( $string ) <= 1 ) { $results [] = $string ; return $results ...Show All

• Visual C# Detecting changes for "Save" and "Save As..." purposes

  I have a base abstract class that contains a generic dictionary. All of the derived concrete classes inherit this dictionary. The Value of the dictionary is of the base class Type. This is to allow adding/deleting of derived types. Ok, what I would like to do, is detect when changes have been made in the object model, so that I can implement a "Save" and "Save As..." method. What is available out there that allows me to do something like this For your custom object type, you have to implement the Equal() method yourself to tell in what condition the two objects of that class is equal. public class Robot {         private string name = "";        ...Show All

• Visual Studio Team System Schema compare locks up

  I ran a schema compare between two live databases. While in the process of choosing to skip certain objects, I clicked on update for an object and the application froze. I checked task manager and my processor was at 100% and devenv.exe had 99% of the CPU cycles. After 4-5 minutes, I killed the process. I had tried the same compare multiple times. It seems to function properly the first time I select schema compare, choose objects to skip, and then script the changes, but on the second time I execute it, on about the 20th change from update to skip, the visual studio freezes. This is the trial version of visual studio team suite with the database professional edition and I have applied the team services service pack. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Indexed Vertices - (in)visibility through index flip?

  This is more a basic question and I currently lack the time to try it myself, so I hope that somebody can give me an answer to this: Considering you have a huge vertex buffer and index buffer that you blast to a shader, forming e.g. 100.000 primitives. Now I would like to hide a bunch of known primitives completly and I know that they form a fully enclosed form like a pyramid or a cube. Extracting them from the buffer would of course be an expensive operation as I would have to rebuild the buffers. But would it work if I just go ahead and flip the indexes in the index buffer for each triangle, e.g. the first and the second from each From my understanding the object would effectively become invisible (if the camera does not move inside t ...Show All

• SQL Server InteractiveSize not behaving

  Hello, I'm having an issue where a report's Interactive Size property is not obeying what I tell it. My report has the standard portrait settings (8.5x11 for PageSize and InteractiveSize). However, when I render the report in Visual Studio, the pages' lengths are obviously much taller than 11 inches. Therefore, the number of pages in the viewer are much less then when I actually print the report. As an aside, if I set my InteractiveSize's height component to 7 inches, only then is the viewer close to the printed output. I have no idea where the 4 inches is going. Also, I have tried all kinds of iterations of substracting margins from my height and it brings me no where close to where it should be. Any ideas ...Show All

  We are using Team Foundation Server Workgroup edition. I open up Microsoft Project and 'Choose Team Project'.

• Visual Studio 2008 (Pre-release) Why does ClientBase Dispose need to throw on faulted state? (Or, what's the difference between close and abort?)

  Could someone enlighten me as to why calling Dispose on a faulted client proxy needs to throw an CommunicationObjectFaultedException instead of just aborting the client   Essentially we have to do this: Client c = new Client(); try {  c.Foo();  c.Close(); } catch (Exception) {  c.Abort();  throw; } Instead of: using(Client c = new Client()) {  c.Foo(); } Yes, I've read the justifications in the SDK and here: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=627970&SiteID=1  but the "summary of internal discussion" seems to be "well, that's what we're doing, so deal with it." I still don't understand why Close must throw instead of just, well, closing I know I'm going to have to live with i ...Show All

• Visual Studio Team System MS Project and TFS questions

  Here are some more issues that my client has encountered while using MS Project with TFS. Are there any work arounds 1. TFS seems unable to deal with special characters such as brackets ' [' e.g. Smith, John [ABC Company]. When synchronizing Project after making changes on TFS, it doesn seem to be ok with special characters like commas and parentheses ',' and '(' e.g. Smith, John (JohnSmith) 2. When changes are made to Remaining Work and completed work, how does MS Project interpret those updates It seems that the finish dates are dependent on the values entered in TFS. There is no easy way to 'approve' the changes before the update is done ( like with PWA). Hey...if your company having the VSIP membership or gold partne ...Show All
