SiOpen return NULL

[malfatti]

Hi all!

I´am writing you expecting some help because I no have ideia how to solve my problem.

I have two codes, the first is the 3DxTest that comes with 3DConnecion SDK. This code works rigth. The problem is, that in my opengl graphics application, that I use the same code that 3DTests, the function SiOpen returns NULL;

Here is my codes:

Code: Select all

bool CVRMouse3D::Init(HWND hWndMain) 
{
	//variaveis locais
	int res;                             
	SiOpenData oData; 

	//Inicialização do dispositivo
	if (SiInitialize() == SPW_DLL_LOAD_ERROR) 
	{
		return false;
	}

	SiOpenWinInit(&oData, hWndMain);    
	SiSetUiMode(NULL, SI_UI_ALL_CONTROLS);
	devHdl = SiOpen ("DefaultApp", SI_ANY_DEVICE, SI_NO_MASK,  SI_EVENT, &oData);

	return  devHdl ? true : false;
}

I have tested the hwndmain reference and its a valid pointer. Some ideia?

Thank you!

Here is the code that I use to create my Window:

Code: Select all

void CVRWindow::Show()
{
	WNDCLASSEX	windowClass;//Window class
	DWORD		dwExStyle;//Window extended style
	DWORD		dwStyle;//Window style
	RECT		windowRect;//Rect used to store the window dimensions

	/*Init window rect values*/
	windowRect.left = (long) 0;
	windowRect.right = lWindowWidth;
	windowRect.top = (long) 0;
	windowRect.bottom = lWindowHeight;

	/*Fill out the window class structure*/
	windowClass.cbSize = sizeof(WNDCLASSEX);
	windowClass.style = CS_HREDRAW | CS_VREDRAW;
	windowClass.lpfnWndProc = MainWindowProc;
	windowClass.cbClsExtra = 0;
	windowClass.cbWndExtra = 0;
	windowClass.hInstance = hInstance;
	windowClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);//Default icon
	windowClass.hCursor = LoadCursor(NULL, IDC_ARROW);//Default arrow
	windowClass.hbrBackground = NULL;//Don´t need background
	windowClass.lpszMenuName = NULL;//No Menu
	windowClass.lpszClassName = "DefaultApp";//Window class name
	windowClass.hIconSm = LoadIcon(NULL, IDI_WINLOGO);//Windows logo small

	//Register the window class
	if (!RegisterClassEx(&windowClass))
	{
		return;
	}

	/*Testing the fullScreen flag*/
	if (bFullScreen)
	{
		DEVMODE dmScreenSettings;//Device mode
		memset(&dmScreenSettings, 0, sizeof(dmScreenSettings));//Inits the device
		dmScreenSettings.dmSize = sizeof(dmScreenSettings);//configure the size
		dmScreenSettings.dmPelsWidth = lWindowWidth;//Screen width
		dmScreenSettings.dmPelsHeight = lWindowHeight;//Screen height
		dmScreenSettings.dmBitsPerPel = uiWindowDepth;//bits per pixel
		dmScreenSettings.dmFields = DM_BITSPERPEL | DM_PELSWIDTH | DM_PELSHEIGHT;//Config the pixels type
		
		/*Test if the screen change was sucessful*/
		if (ChangeDisplaySettings(&dmScreenSettings, CDS_FULLSCREEN) != DISP_CHANGE_SUCCESSFUL)
		{
			//Setting display mode failed, switch to windowed
			MessageBox(NULL, "Configuração de vídeo não disponível",NULL, MB_OK);//Show the error message
			bFullScreen = false;//Change resolution back
		}
	}

	//Verify if we are still in fullscreen mode
	if (bFullScreen)
	{
		dwExStyle = WS_EX_APPWINDOW;
		dwStyle = WS_POPUP;
		ShowCursor(FALSE);
	}
	else
	{
		dwExStyle = WS_EX_APPWINDOW | WS_EX_WINDOWEDGE;
		dwStyle = WS_CAPTION |WS_SYSMENU;
	}

	/*****Adjust window to true requested size******/
	AdjustWindowRectEx(&windowRect,dwStyle, FALSE, dwExStyle);


	/******Class registered, so now we will create our window*****/
	hwnd = CreateWindowEx(NULL, 
						"DefaultApp",
						cTitle,
						dwStyle | WS_CLIPCHILDREN | WS_CLIPSIBLINGS,
						xPos, yPos,
						windowRect.right - windowRect.left,
						windowRect.bottom - windowRect.top,
						NULL,
						NULL,
						hInstance,
						NULL);

	/******Show the window*****/
	ShowWindow(hwnd,SW_SHOW);
	UpdateWindow ( hwnd );
}

Trying to solve this problem I paste the code of my project into that visual studio project that comes with SDK and works!

So my conclusion is that in my own project exist some missing configuration parameter!

I will to comare both projects to discover what is missing.
