• Game Technologies: DirectX, XNA, XACT, etc. XNA GSE - Vista installation

  Hello all, I'm running the latest Vista Ultimate (MSDN) version on my machine. For some reason I can't get GSE to install. At the end of the setup, Microsoft Visual C#  Express crashes and the setup is rolled back. Always when it states "Registering project templates". Like the Visual C# Express site suggests, I've tried uninstalling the product, and re-install it as an Administrator user. But that doens't work either. Afterwards I receive the same behavior. I've also ran the GSE setup as an Administrator, but still no luck. Thanks for all suggestions and help! Okay, let me make clear that I know it isn't supported... However, there are plenty of people I've seen blogging about XNA t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Memory leaks disposing AudioVideoPlayback.Video object

  Hello. Sorry if this question is not in the right thread. I'm writing C# application for continuous video playback using the Video class from AudioVideoPlayback namespace. I create new Video object for each movie clip disposing previous one and I face the memory leak problem if I set Audio.Volume property somewhere; the Audio object is not disposed. This leads to E_OUTOFMEMORY exception when trying to play 10th or 20th clip. Now I've commented lines that change Audio.Volume and application operates normally. Is there any way out of the situation I don't like the idea to change the master volume... Thanks in advance, Victor. ...Show All

• Visual C# Problems with assembly references

  Hi, I am developing a windows service application which refers to the class library A and this class library A refers to my windows service application.

• SQL Server SSRS 2005

  I have somehow hidden the details on the HOME page of my Report Server. All i see is HOME and the line below it. Nothing esle. Any ideas We have the same situation on a clients system.

• Visual C# How to get the width of a character?

  Basically I am trying to make a console type application. And I am trying to figure out how to make it so the window is like 100 characters wide. I am using a monospaced font (Courier BT) so I was wondering if there was a way to figure out the width of each character given the font and the font point size. Thanks in advance Nevermind I figured it out. For some reason TextRenderer.MeasureText() measures the first char as double the real size of it. So like TextRenderer("M", FONT) will return 14, but TextRenderer("MM", FONT) will return 21. I don't know if this is how they intended it to be but I just took the result of TextRenderer("M", FONT), divided by 2 and multiplied by th ...Show All

• Windows Forms Web Form Designer

  Hi! Well, I'm not sure whether I'm posting at the right forum. But I'm not sure, what I need is possible at all. I have developed a windows form designer which can create and edit windows forms, just like VS2005. Now, my question is: Can I develop a web form designer that can create and edit ASP.NET Forms. Has Microsoft exposed the interfaces that can be implemented to host web forms. If yes, how it would be possible. If no, are there any alternatives, any existing products that I can buy Waiting for a quick response... ...Show All

• Visual C++ Edit and continue does not work (for me) with VC2005

  Since "up"grading from VS2003, I have been unable to use edit and continue. Whenever I try, I get the error message: "Project : error PRJ0046 : Could not spawn command line because the one specified was empty." Are there any suggestions about getting this to work I'm very surprised that VC2005 doesn't just work out of the box. (This was never a problem with VC2003.) Sorry for the late reply. I was out of the office for a couple weeks, and then swamped when I got back. First of all, after a bit more investigation, the reason it worked for me originally is that I copied the solution (including the built .exe) to the mapped drive, which turns out to not be the same as build ...Show All

• Visual Studio Express Editions Drawing Ellipses at a specified angle (not aligned to the x or y axis)

  I am trying to draw an ellipse at the centre of a panel such that the semi major axis of the ellipse is rotated at a user specified angle ie. rotated ellipse. I have no problem drawing an ellipse at the centre of a panel provided there is no rotation applied, but as soon as I try to rotate the ellipse I fail to achieve the desired result. The method I have tried is to use the Graphics.RotateTransform and graphics.TranslateTransform methods. The Graphics.RotateTransform method seems to rotate about the origin (0,0) point of the panel, so I have tried the following: First draw the ellipse centred at (0,0) Rotate the ellipse using the Graphics.RotateTransform method Translate the elipse to the centre of ...Show All
