Hi, I seem to be having a problem when I try to create a Directx9 device for fullscreen. It works fine in windowed mode. Here is how I am setting up the D3DPRESENT_PARAMETERS structure:


D3DPRESENT_PARAMETERS d3dpp;
d3dpp.AutoDepthStencilFormat = D3DFMT_D16;
d3dpp.BackBufferCount = 1;
d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8;
d3dpp.BackBufferHeight = 640;
d3dpp.BackBufferWidth = 480;
d3dpp.EnableAutoDepthStencil = TRUE;
d3dpp.Flags = 0;
d3dpp.hDeviceWindow = hwnd;
d3dpp.MultiSampleQuality = 0;
d3dpp.MultiSampleType = D3DMULTISAMPLE_NONE;
d3dpp.PresentationInterval = 0;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
	
	
#if defined (FULLSCREEN)
	d3dpp.Windowed = FALSE;
	d3dpp.FullScreen_RefreshRateInHz = 60;
#else
	d3dpp.Windowed = TRUE;
	d3dpp.FullScreen_RefreshRateInHz = 0;
#endif

Creating the device:


HRESULT hr = g_d3d9->CreateDevice (D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL,  hwnd, 									D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp, &g_d3d9Device);

The Output from Debug:

Quote: Direct3D9: (INFO) :Direct3D9 Debug Runtime selected. Direct3D9: (INFO) :======================= Hal SWVP device selected Direct3D9: (INFO) :HalDevice Driver style 9 Direct3D9: :Subclassing window 000e066e Direct3D9: :StartExclusiveMode Direct3D9: (ERROR) :The specified mode is unsupported.

I am new to DirectX, so I am not sure how to interpret some of this. I googled around for a few hours yesterday and today, and know that this is a common problem when an incorrect value is specified as part of the D3DPRESENT_PARAMETERS structure. I checked the settings I am using with the DXCapsViewer utility, and they all appear to be valid modes. I also tried setting the Device Type to D3DDEVTYPE_REF, but that didn't help either. I have also read, that when using Fullscreen, that the HWND being past in must be a top level window, so I have also specified that. Actually, here's the Window creation code:


HWND hwnd = CreateWindowEx (WS_EX_OVERLAPPEDWINDOW | WS_EX_TOPMOST, "STATIC", "Small", 
								WS_POPUP | WS_VISIBLE, 
								0, 0,
								640, 480,
								0, 0, hInstance, 0);

This whole thing is a very bare bones application, as I am working on producing a sub 4kb executable. So I am also not linking to any common libs other than kernel32.lib and user32.lib, as well as d3d9.lib, just in case that has something to do with it. Thanks, caseyd

You need to find out whether the mode you want to go into in full screen is acceptable.

Try something like:

D3DDISPLAYMODE DisplayMode;m_pD3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &DisplayMode);hr = m_pD3D->CheckDeviceFormat(D3DADAPTER_DEFAULT,D3DDEVTYPE_HAL,DisplayMode.Format,D3DUSAGE_RENDERTARGET,D3DRTYPE_SURFACE,D3DFMT_A8R8G8B8);if( FAILED(hr) ) {	MessageBox(NULL,"Device format is unaccepatble for full screen mode","Sorry",MB_OK);	return E_FAIL;}//set fullscreen parametersm_PresentParameters.BackBufferFormat = D3DFMT_A8R8G8B8;m_PresentParameters.Windowed = FALSE;m_PresentParameters.BackBufferWidth = DisplayMode.Width;m_PresentParameters.BackBufferHeight = DisplayMode.Height;m_PresentParameters.hDeviceWindow = m_hwnd;					//window handle

Please don't PM me with questions. Post them in the forums for everyone's benefit, and I can embarrass myself publicly.

I think I spotted a classic little 'gotcha' in your code [wink]

Quote:d3dpp.BackBufferHeight = 640;
d3dpp.BackBufferWidth = 480;

I think you might want to swap those two values around... [smile]

The depth-buffer format looks suspect to me. A lot of cards don't support a depth buffer that isn't the same bit-depth as the backbuffer. You should check support with IDirect3D9::CheckDepthStencilMatch. From my engine code:

D3DFORMAT PGraphics::GetDepthBufferFormat(D3DFORMAT fmtBackBuffer){D3DFORMAT fmtBuffers[] = {	D3DFMT_D24S8,	D3DFMT_D32,	D3DFMT_D24X8,	D3DFMT_D24FS8,	D3DFMT_D24X4S4,	D3DFMT_D15S1,	D3DFMT_D16,	D3DFMT_D32F_LOCKABLE,	D3DFMT_D16_LOCKABLE};const char* szBuffers[] = {	"D3DFMT_D24S8\n",	"D3DFMT_D32\n",	"D3DFMT_D24X8\n",	"D3DFMT_D24FS8\n",	"D3DFMT_D24X4S4\n",	"D3DFMT_D15S1\n",	"D3DFMT_D16\n",	"D3DFMT_D32F_LOCKABLE\n",	"D3DFMT_D16_LOCKABLE\n"};D3DFORMAT fmtAdapter;	// Get adapter format	if(m_thePresentParams.Windowed)	{		D3DDISPLAYMODE mode;		if(FAILED(m_pD3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &mode)))			return D3DFMT_UNKNOWN;		fmtAdapter = mode.Format;	}	else		fmtAdapter = fmtBackBuffer;	// Check formats	ELog::Get().SystemLog("RENDER  : Choosing depth-stencil format... ");	for(DWORD i=0; i<sizeof(fmtBuffers)/sizeof(D3DFORMAT); ++i)	{		HRESULT hResult = m_pD3D->CheckDeviceFormat(D3DADAPTER_DEFAULT, m_eDevType,			fmtAdapter, D3DUSAGE_DEPTHSTENCIL, D3DRTYPE_SURFACE, fmtBuffers);		if(FAILED(hResult))			continue;		if(SUCCEEDED(m_pD3D->CheckDepthStencilMatch(D3DADAPTER_DEFAULT, m_eDevType,			fmtAdapter, fmtBackBuffer, fmtBuffers)))		{			ELog::Get().SystemLog(szBuffers);			return fmtBuffers;		}	}	ELog::Get().SystemLog("Failed\n");	return D3DFMT_UNKNOWN;}

That code goes through each of the listed formats in turn, and checks first if the format is available (The card supports that format at all), and then if the format is usable in the specified display mode, with the specified backbuffer format.

Yep, that was it.

Thanks!
