• Visual C# how to return null from a constructor

  say, i a m trying to do something like: class something something(streamreader){ if (wrong format or end of file) caller receives null as result else build object from what has been read in file } i tried 'return null', but it says it can not do that since a constructor is 'void', so i can not place a return sentence. i'm not sure something like this.dispose would retunr a null, since the 'dispose' may be asynchronous (or something) i have the next alternative class something blah blah somehting(string) (build object from string, check if string==null or wrong format before calling) static bool checkformat(string) check to see if string is adecuate to build somet ...Show All

• .NET Development .net, .mdb, and the framework

  I am a consultant and I have commissioned work from a programmer I have hired, the software is written in .net for Windows and is not web based. The problem we are having is causing us to pull our hair out. The problem is this: On the developers WinXP machine with 03 visual studio the application he wrote works phenomenally well. On my machine Win2K no visual studio the application he wrote works phenomenally well. The unfortunate problem is that the CLIENT has installed the same application multiple times (XP SP1 and SP2) and is consistently getting the table display errors, either to do with the database access or something to do with the draw routine. He has installed .NET framework 1.1 from MSFT multiple times but its always a no go. I ...Show All

• .NET Development Static classes with codedom

  If I create a class using CodeTypeDeclaration, how can I make that class static Something like: CodeTypeDeclaration myType = new CodeTypeDeclaration( "MyClass" ); myType.TypeAttributes = TypeAttribute.Static; Unfortunately there is no TypeAttribute.Static (why Did anyone miss anything ), so the above code won't compile. How can I achieve this Thanks for any help. The CodeDom is language independent. A static class is a C# thing. Therefore you can't directly create a static class through the CodeDom. In fact you can't even set up the appropriate attributes to get it to work. A static class is really just an abstract, sealed class. However attempting to do this through the DOM will fail.

• .NET Development Create Image in VC++ 6.0

  This is an out of time question, but I don't know any other way to solve my problem. What I need is a piece of sample code , in old VC++ 6.0 style, which creates an Image from a memory buffer containing image data (as those got from an IP camera). In VisualStudio.NET 2005 and C# this is done in 2 simple lines of code: MemoryStream mstr = new MemoryStream(imageBuffer); Image img = Image.FromStream(mstr); But I don't know how to do it in Visual C++ 6.0 The problem comes from the fact I want to develop an ActiveX control (unmanaged) to show the live video of an IP camera. I already did it in VisualStudio.NET, but this way the control can only be used with IIS, while I must use Apache or Tomcat as web server. Thanks ...Show All

  I am trying to build a voting system. Website visitors will rate a pictures from 0-10. This value should update the amount of points already stored is SQL.

Does anybody there could post a piece of code or point to a link where I could find this information thanks Jens, thanks again for helping! If you don't mind I would like both.

• Visual Studio Team System Removing User option under "Assigned To"

  We have recently removed the permissions from an employee that is no longer with the company (he doesn't have access to TFS), but each individual in various groups still have the option to add him as an "Assigned To:" value. Is there anyway to keep the history in the database as to what he worked on while removing him from the option in the field Moved thread to Work Item tracking, since "assigned to" is exclusive to WIT. I think you just need to remove him from any *other* groups to which he belongs (is he a user, admin, or contributor on any team projects, or in any of the project groups ), and he'll be removed from Valid Users as well (but it may take a few minutes to sync). Anything referring to " ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Camera translation in a 2D environment

  I'm trying to build a platformer, but I can't figure out how to do camera translation in the 2D space. I'm using sprites for the environment and characters... How would I achieve camera movement in this situation I've tried messing around with the BasicEffect class (since I read on the forum that that's where you should move the camera), but to no avail. Thanks in advance. If you are using SpriteBatch, then you are using Screen coordinates.  There are no Effects, vertex shaders, or other forms of vertex processing.  Since BasicEffect is an Effect, which the SpriteBatch draw operations will not be processed by, using it will do nothing for you. If you wan't to translate the positions of your ...Show All

• Visual C# Debug Deployment taking forever

  I am deploying my app to a Windows Pocket PC 2003 Device. When I deploy its taking close to 10 minutes to deploy. The app is only 104K on my device. I noticed that it is hanging specifically on these files: System.Data.dll System.Windows.Forms.dll System.Web.dll System.Design.dll System.DataOracleClient.dll (Im not even using Oracle) Then these files are also being transfered and popping up a msg box stating that "Windows SQL Server Mobile is aready installed.
