This program compiles just fine, but when it runs it throws this error: Unhandled exception at 0x011627d6 in dx1.exe: 0xC0000005: Access violation reading location 0x00000030.

When I go into debugging, it says the problem is with line 313:

hResult = pd3dDevice->CreateOffscreenPlainSurface(width, height, D3DFMT_X8R8G8B8, D3DPOOL_DEFAULT, &surface, NULL);

However, up near the top of the program (line 26) I declare a variable for holding a font object:

LPD3DXFONT d3dFont;

If you comment out that line then the program suddenly works. I have commented out all the code that uses the font object, so I am fairly certain that this is the problem.

Anyone have any ideas? All help is GREATLY appreciated. Been searching for hours to no avail. I am using Visual Studio 2010 in case that's relevant.
