Help with using WGL

Using SDL or the like will save you a lot of pain.

http://www.opengl.org/wiki/Creating_an_OpenGL_Context_(WGL) had information on using WGZl and extensions to set up your own context and at least points you in the right direction for sRGB.

This *should* create a GL3.3 core window. Note I've removed all error checking etc. just to show what needs to be done. Always make sure your hWnds, hDCs and hGLRC are valid. It assumes you're using GLEW.

Edit to add: It also assumes you know Win32...

Look for wglChoosePixelFormatARB (and the structure above it) near the bottom of the code.

HWND CreateGLWindow( void )
{
	HWND hWnd;
	HDC hDC;
	HGLRC hGLRC;
	WNDCLASSEX wc;
	PIXELFORMATDESCRIPTOR pfd;

	// create dummy GL window and get function pointers from GLEW

	ZeroMemory( &wc, sizeof( WNDCLASSEX ) );

	wc.cbSize = sizeof( WNDCLASSEX );
	wc.style = CS_OWNDC | CS_HREDRAW | CS_VREDRAW;
	wc.lpfnWndProc = (WNDPROC) DefWindowProc;
	wc.cbClsExtra = 0;
	wc.cbWndExtra = 0;
	wc.hInstance = GetModuleHandle( NULL );
	wc.hIcon = 0;
	wc.hCursor = NULL;
	wc.hbrBackground = 0;
	wc.lpszMenuName = 0;
	wc.lpszClassName = L"dummy window class";
	wc.hIconSm = 0;

	RegisterClassEx( &wc );
	
	hWnd = CreateWindowEx( WS_EX_APPWINDOW, L"dummy window class", L"", WS_OVERLAPPEDWINDOW | WS_CLIPCHILDREN | WS_CLIPSIBLINGS, 100, 100, 800, 600, NULL, NULL, GetModuleHandle( NULL ), NULL );

	hDC = GetDC( hWnd );

	ZeroMemory( &pfd, sizeof( PIXELFORMATDESCRIPTOR ) );

	pfd.nSize = sizeof( PIXELFORMATDESCRIPTOR );
	pfd.nVersion = 1;
	pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER;
	pfd.iPixelType = PFD_TYPE_RGBA;
	pfd.cColorBits = 32;
	pfd.cDepthBits = 24;
	pfd.cStencilBits = 8;

	SetPixelFormat( hDC, ChoosePixelFormat( hDC, &pfd ), &pfd );
	hGLRC = wglCreateContext( hDC );

	wglMakeCurrent( hDC, hGLRC );

	glewInit();

	wglMakeCurrent( NULL, NULL );
						
	wglDeleteContext( hGLRC );

	DestroyWindow( hWnd );

	UnregisterClass( L"dummy window class", GetModuleHandle( NULL ) );



	// Create GL window

	ZeroMemory( &wc, sizeof( WNDCLASSEX ) );

	wc.cbSize = sizeof( WNDCLASSEX );

	wc.hInstance = GetModuleHandle( NULL );
	wc.hIcon = 0;
	wc.hCursor = NULL;
	wc.hbrBackground = 0;
	wc.lpszMenuName = 0;
	wc.lpszClassName = L"Window Class";
	wc.hIconSm = 0;

	RegisterClassEx( &wc );

	hWnd = CreateWindowEx( NULL, L"Window Class", L"Window Caption", WS_OVERLAPPEDWINDOW | WS_CLIPCHILDREN | WS_CLIPSIBLINGS, 100, 100, 800, 600, NULL, NULL, GetModuleHandle( NULL ), NULL );

	hDC = GetDC( hWnd );

	const unsigned int maxFormats = 20; // max number of returned pixel formats
	int pixelFormats[maxFormats]; // array of returned pixel formats, best at index 0...
	unsigned int numFormatsAvailable; // number of matching formats

	const int pfdAttributes[] =
	{
		WGL_DRAW_TO_WINDOW_ARB, GL_TRUE,
		WGL_SUPPORT_OPENGL_ARB, GL_TRUE,
		WGL_DOUBLE_BUFFER_ARB, GL_TRUE,
		WGL_FRAMEBUFFER_SRGB_CAPABLE_ARB, GL_FALSE,
		WGL_ACCELERATION_ARB, WGL_FULL_ACCELERATION_ARB,
		WGL_PIXEL_TYPE_ARB, WGL_TYPE_RGBA_ARB,
		WGL_COLOR_BITS_ARB, 32,
		WGL_DEPTH_BITS_ARB, 24,
		WGL_STENCIL_BITS_ARB, 8,
		0
	};
				
	wglChoosePixelFormatARB( hDC, pfdAttributes, NULL, maxFormats, pixelFormats, &numFormatsAvailable );

	SetPixelFormat( hDC, pixelFormats[0], &pfd );
				
	const int glContextAttributes[] =
	{
		WGL_CONTEXT_MAJOR_VERSION_ARB, 3,
		WGL_CONTEXT_MINOR_VERSION_ARB, 3,
		//WGL_CONTEXT_PROFILE_MASK_ARB, WGL_CONTEXT_COMPATIBILITY_PROFILE_BIT_ARB,
		WGL_CONTEXT_PROFILE_MASK_ARB, WGL_CONTEXT_CORE_PROFILE_BIT_ARB,
		0
	};

	hGLRC = wglCreateContextAttribsARB( hDC, NULL, glContextAttributes );

	wglMakeCurrent( hDC, hGLRC );

	ShowWindow( hWnd, SW_SHOW );
	
	return hWnd;
}

Thanks Mark, I believe that was exactly what I was looking for.
