      • I have created a Visual Studio project template that can be built for either Xbox 360 or Windows, by selecting the correct platform in the VS IDE. There's nothing particularly clever about this, it just uses some of the conditional abilities of MSBuild projects to merge the properties of an Xbox 360 XNA project with a Windows XNA project. There's a slight problem though - the VS Express C# IDE has

      • Hi I've got a 2D project where the world is rendered to a 1024x1024 RenderTarget2D texture, then that texture is drawn to the backbuffer. It works fine on my laptop. On my desktop, however, the RenderTarget2D texture is drawn with an overlay of garbage consisting partly of a frame of a DVD I was watching on the other display. I'm clearing the RenderTarget2D texture properly, and everything is draw

Do you know anything about that I should be able to use it. I have a team that wants to use XNA for the PC platform - we could hardly care about the xbox360 at the moment.

I've googled up the subject and whilst there are some good tutorials on how to do it, non of them really explain in simple terms why we should or shouldn't. I just can't seem to get my head around how they work properly.

      • Hi all. First of all, I'm new to DirectX. I'm trying to load an image into a PictureBox component (C#) using DirectX. The problem is that I'm working with large pictures (for ex. 4021x3123) and can't use the Windows GDI, because the picture takes a lot of memory and it flickers when I move the scrollbars. That's why I was thinking of using DirectX. I've linked the DirectX Device with the PictureBo
