I don't understand why I get errors on this line...


Texture characters = new Texture(graphics.Device, Bitmap.FromFile("graphics/wee.bmp"), Usage.DepthStencil, Pool.Default);

Error 1 The best overloaded method match for 'Microsoft.DirectX.Direct3D.Texture.Texture(Microsoft.DirectX.Direct3D.Device, System.Drawing.Bitmap, Microsoft.DirectX.Direct3D.Usage, Microsoft.DirectX.Direct3D.Pool)' has some invalid arguments C:\Documents and Settings\ryan\Desktop\RCade\frmGame.cs 21 34 RCade Error 2 Argument '2': cannot convert from 'System.Drawing.Image' to 'System.Drawing.Bitmap' C:\Documents and Settings\ryan\Desktop\RCade\frmGame.cs 21 63 RCade

hmm...maby its becuase my device isn't being created :D. I have a picturebox, which I pass the handle to my class which initalizes Direct3D.

EXCEPTION:

Microsoft.DirectX.Direct3D.InvalidCallException was caught  Message="Error in the application."

my params

Try using TextureLoader if it's from a file. Won't solve the error probably, but it will sure speed up things.

in your project properties, enable unmanaged debugging.
Also, go into the control panel and into the directX page, then set direct3d to the debug runtime and full debugging.
Now, when the error occurs you should get a detailed explaination in the output window.

Ugh, read the messages. System.Drawing.Bitmap.FromFile does not return a Bitmap. Thus you're trying to pass Not a Bitmap to something that expects a Bitmap and it fails.

As Alex says, TextureLoader.FromFile is a bit nicer to deal with.
