Hi,
I am using VC++ .NET and i wrote this program while using VC++ 6. It still works fine on my one machine that has VC++ 6. But when i try to run my code in VC++ .NET the CreateDevice() function in directx function fails. I have not changed the code at all. I'm still new to D3D but I am wondring if theres anyhting wrong withthe way i'm initilizing it. I'm using April 2005 directx sdk and under win xp with VC++ .NET.
Heres my D3d initilaize function. The code fails at the g_pD3D->CreateDevice(...) call at the end there.
Code:
HRESULT InitializeD3D(HWND hWnd)
{
UINT nWidth = 800;
UINT nHeight= 600;
//First of all, create the main D3D object. If it is created successfully we
//should get a pointer to an IDirect3D8 interface.
g_pD3D = Direct3DCreate9(D3D_SDK_VERSION);
if(g_pD3D == NULL)
{
return E_FAIL;
}
//Get the current display mode
D3DDISPLAYMODE d3ddm;
d3ddm.Format = CheckDisplayMode(nWidth, nHeight, 32);
if(d3ddm.Format != D3DFMT_UNKNOWN)
{
//Width x Height x 32bit has been selected
d3ddm.Width = nWidth;
d3ddm.Height = nHeight;
}
else
{
d3ddm.Format = CheckDisplayMode(nWidth, nHeight, 16);
if(d3ddm.Format != D3DFMT_UNKNOWN)
{
//Width x Height x 16bit has been selected
d3ddm.Width = nWidth;
d3ddm.Height = nHeight;
}
else
{
return E_FAIL;
}
}
//Create a structure to hold the settings for our device
D3DPRESENT_PARAMETERS d3dpp;
ZeroMemory(&d3dpp, sizeof(d3dpp));
//Fill the structure.
//We want our program to be windowed, and set the back buffer to a format
//that matches our current display mode
d3dpp.Windowed = FALSE;
d3dpp.BackBufferCount = 1;
d3dpp.BackBufferFormat = d3ddm.Format;
d3dpp.BackBufferWidth = d3ddm.Width;
d3dpp.BackBufferHeight = d3ddm.Height;
d3dpp.hDeviceWindow = hWnd;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT;
d3dpp.PresentationInterval = D3DPRESENT_INTERVAL_ONE;
//Select the best depth buffer, select 32, 24 or 16 bit
if(g_pD3D->CheckDeviceFormat(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, d3ddm.Format, D3DUSAGE_DEPTHSTENCIL, D3DRTYPE_SURFACE, D3DFMT_D32) == D3D_OK)
{
d3dpp.AutoDepthStencilFormat = D3DFMT_D32;
d3dpp.EnableAutoDepthStencil = TRUE;
}
else if(g_pD3D->CheckDeviceFormat(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, d3ddm.Format, D3DUSAGE_DEPTHSTENCIL, D3DRTYPE_SURFACE, D3DFMT_D24X8) == D3D_OK)
{
d3dpp.AutoDepthStencilFormat = D3DFMT_D24X8;
d3dpp.EnableAutoDepthStencil = TRUE;
}
else if(g_pD3D->CheckDeviceFormat(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, d3ddm.Format, D3DUSAGE_DEPTHSTENCIL, D3DRTYPE_SURFACE, D3DFMT_D16) == D3D_OK)
{
d3dpp.AutoDepthStencilFormat = D3DFMT_D16;
d3dpp.EnableAutoDepthStencil = TRUE;
}
else
{
d3dpp.EnableAutoDepthStencil = FALSE;
}
//Create a Direct3D device.
if(FAILED(g_pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &g_pD3DDevice)))
{
return E_FAIL;
}
Is there somthing I overlooked when i switched to .NET or is there something wrong with my initilization of D3D?
Thanx in advance,
Boomba,
