I first start off by: SDL_SysWMinfo m_Info; SetEnvironmentVariable("SDL_VIDEODRIVER", "directx"); SDL_Init(SDL_INIT_VIDEO | SDL_INIT_NOPARACHUTE) atexit(SDL_Quit); SDL_SetVideoMode( 800, 600, 0,0); SDL_VERSION(&m_Info.version); SDL_GetWMInfo(&m_Info); // Create Device m_pD3dCOM = Direct3DCreate9(D3D_SDK_VERSION); D3DPRESENT_PARAMETERS d3dpp; ZeroMemory(&d3dpp, sizeof(D3DPRESENT_PARAMETERS)); d3dpp.hDeviceWindow = m_Info.window; d3dpp.Windowed = true; d3dpp.BackBufferCount = 1; d3dpp.Flags = 0; d3dpp.FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT; d3dpp.MultiSampleQuality = 0; d3dpp.PresentationInterval = D3DPRESENT_INTERVAL_IMMEDIATE; d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD; D3DDISPLAYMODE d3ddm; m_pD3dCOM->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3ddm))) m_BPP = GetBPPfromFormat(d3ddm.Format); SetPixelFormat(GetFormatfromBPP(m_BPP)); d3dpp.BackBufferFormat = m_PixelFormat; if (m_bZBuffer) { m_StencilFormat = D3DFMT_D24S8; d3dpp.AutoDepthStencilFormat = m_StencilFormat; } d3dpp.EnableAutoDepthStencil = true; d3dpp.BackBufferHeight = 800; d3dpp.BackBufferWidth = 600; d3dpp.MultiSampleType = m_SampleType; m_pD3dCOM->CreateDevice(D3DADAPTER_DEFAULT, m_DevType,m_Info.window, (DWORD)m_VP,&d3dpp, &m_pD3dDeviceCOM)

then in my loop, i keep getting an error for the Present() function... what's wrong?

i dont know much about directX, but i read once that the SDL library inherits a copy of the enviormental variables, and that any attempts to change them wont affect those in the SDL dll:

Quote:
SetEnvironmentVariable("SDL_VIDEODRIVER", "directx");

this needs to be done either before the program using the dll is loaded or by specifing them in the system enviorment...

maybe thats changed though

i have that line being called right from the beginning

that has no affect, the values are copied _before_ execution starts, so your program and SDL have different ones, and changes in one will not affect the other.

the articles linked above didnt contain any code to change the environment that i could see...

Why do you want to change the environment?

Apart from that, on first glance your D3D initialization looks okay.

Have you tried D3DFMT_D16 for your m_StencilFormat variable?

Can you post some more code around your actual rendering code?

well, turns out i accidently still had the WinMain crap still in there, but now i'm getting some symbol errors:

ahh... haven't ran through that in a while... how do i do that?
