• Game Technologies: DirectX, XNA, XACT, etc. Pulling Data from ContentManager

  I've got a question on why to use the content manager. Say I have loaded a texture into the content manager - paddle = content.Load< Texture2D >( @"Graphics\paddle" ) as Texture2D ; If I want to access the data from the content manager, would I have to put something like this - sprites.Draw(content.Load< Texture2D >( "Graphics\\paddle" ), new Vector2 ( this .paddle1.Point.X, this .paddle1.Point.Y), Color .White); Or is there an easier way then that Cause if I have made a texture variable, then loaded it into the content manager, why couldnt I just call the variable directly like this - sprites.Draw( this .paddle, new Vector2 ( this .paddle1.Point.X, this .paddle1.Point. ...Show All

• Smart Device Development Who has a PPC-6700 Sprint AudioVox Mobile 5 (Can I use GPS?)

  I have the Sprint AudioVox PPC-6700 and I know that it has the built in GPS chipset but everywhere that I search I can not find out how to actually access the API. There are a few of the GPS API references throughout msdn & msdn2 but none have an actual walk through. It is very easy to access the phone API's and contact lists/appointments and whatnot but the GPS is not to be found. As far as the GPS is conserned one could argue that it isn't ment to be programmed or something but the fact is that in all documentation it says that e911 can use the gps and also applications that need your location (such as movie times or resteraunts in your location). I really need to find out how to manage this out even with just a simple quord ...Show All

When I set my application to load the movie I know my it is running from Application.StartupPath and can refer the movie as Application.StartupPath + "Fun.mpg" ...Show All

• SQL Server Execute Package Task always fails.

  I have a package (i.e. child package) which runs itself perfectly fine without displaying any error. However when I embeded this package inside another package (i.e. parent package) using Execute Package Task. The task always fails. It seems strange enough. The child package has two variables that need to be passed in from parent package. Can any expert here please help out Thanks. - Steve Personally, I do not see that such pain you are taking about. If you are copying a DataFlow task from one package to another; you would need eventually to check or re-define your connection managers; since you may need the same combination of tasks but different connections. Changing the connection managers inside of a task is ...Show All

• Visual Studio Extremely poor performance from VS 2005 before and after SP1 install (large files)

  I've been having some pretty significant problems with Visual Studio 2005, which are now to the point where basic tasks have become near impossible. I have a large solution that I'm working with that contains several projects (one C++ COM server, a few C# class libraries, a web service, and a C# Winforms app), and I find that very frequently, the CPU usage on my machine (single P4 CPU on Server 2003) will spike to 100%, and the memory usage in the task manager will increase to 900 Mb or more when doing nothing but editing text in a .cs, .cpp, or .h file. This seems to happen much more frequently on longer files (1000 lines or more). I just had my machine lock up again by adding a single line of code to a header file. By sea ...Show All
