• Visual C# Does a C# Windows Service running on "local system" or "local service" have access to environment variable such as PATH?

  I have created a windows service and deployed it using a setup project (.msi installer). I am wondering if the service has permission to access the windows environment variables such as PATH any help would be appreciated. Thanks, Keith Yes I am trying this. To give you some background I have a console program which references some third party software. This line of code starts an .exe process on the system, to do this it must access the PATH variable on the system. When I convert this over to a windows service, everything runs fine except for this one line of code which starts the .exe process. If this .exe process is running before this line of code is executed, the service runs correctl ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to draw to an offscreen texture (for screen effects and video feedback)

  I'd like to do some screen effects with a pixel shader and maybe also some video feedback stuff. I'm trying to figure out how to render to a texture (maybe an Offscreen Surface ) which I'll then be able to render back on to the graphics device's buffer. I'm not sure whether I should use GraphicsDevice.CreateOffscreenPlainSurface or GraphicsDevice.CreateRenderTarget or what sort of paramters I should feed to either of those. The once I've got a Surface created by one of those methods, I'm not sure how to set it as a render target... GraphicsDevice.GetRenderTarget with an index above 0 always throws an exception, so I'm guessing there is some way to explicitly add Surfaces to GraphicsDevices as a render target that I can't seem to figure out ...Show All

• Visual Studio 2008 (Pre-release) XBAP / JavaScript

• Game Technologies: DirectX, XNA, XACT, etc. Is it realistic to create one's own engine?

  I'm not new to programming, but I'm new to game programming and C#. I'm wondering to what extent it's realistic for someone to make their own 3D (or for that matter 2D) game engine. The two projects I have in mind for myself are a turn-based 2D war/strategy game, and a 3D adventure game in the manner of "Dreamfall". On the 2D side, I feel confident I could come up with a 2D interface on my own. I haven't done a lot here yet, but I did manage to whip up a little 2D hockey game without peeking at Bill Reiss's excellent 3D airhockey tutorial at http://xna101.spaces.live.com/ . I've even given my computer hockey opponent a very primitive AI. OK, my collision detection and physics aren't great, but I'm not sure how much I'll need either of ...Show All

• Visual Studio Express Editions Gobal imports. Is this possible?

  Hi Quick question, is it possible to have a global imports statment in a module which can then be used by all forms in the application instead of having to write an imports statment in every form. e.g I have Imports System.Data Imports System.Data.SqlClient These are in a module, but are not referenced by the forms. Is there a way to publicly declare this. Any help is appreciated.
