Thread: OpenGL with WIN 32

Hello,
I'm learning OpenGL, but I have lots of troubles at startup!
I want to draw some stuff in a window, so I "create" rendering context and make it corrent.After all I release and delete the device, but it don't work. I do this all in the window procedure as follows:

Code:

....
case WM_CREATE:
		PIXELFORMATDESCRIPTOR pfd;
		hDC = ::GetDC(hwnd);
		ZeroMemory( &pfd, sizeof( pfd ) );
		pfd.nSize = sizeof( pfd );
		pfd.nVersion = 1;
		pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL |
             PFD_DOUBLEBUFFER;
		pfd.iPixelType = PFD_TYPE_RGBA;
		pfd.cColorBits = 24;
		pfd.cDepthBits = 16;
		pfd.iLayerType = PFD_MAIN_PLANE;
		iFormat = ChoosePixelFormat( hDC, &pfd );
		SetPixelFormat( hDC, iFormat, &pfd );
		hRC = wglCreateContext( NULL );
		hRC = wglCreateContext( hDC );
		if(!wglMakeCurrent( hDC, hRC ))
			MessageBox (NULL, "Main Window Initialization ERROR!",
				"OpenGL Tester",MB_DEFBUTTON1);
	case WM_PAINT:
		glClear(GL_COLOR_BUFFER_BIT);
		glBegin(GL_POLYGON);
		glColor3f(1, 0, 0);
		glVertex2f(-5, -5);
		glVertex2f(-5, 5);
		glColor3f(0, 0, 1);
		glVertex2f(5, 5);
		glVertex2f(5, -5);
		glEnd();
		glFlush();
		break;
     case WM_DESTROY:
		wglMakeCurrent( NULL, NULL );
		wglDeleteContext( hRC );
		::ReleaseDC( hwnd, hDC );
		::PostQuitMessage (0);
        return 0; // return zero when processed

If somebody can help me, I'l be happy.
Thank you in advance!

How can I do that?
This procedure is called while the window is creating and it will call this render() function before hDC ad hRC are ready and before call of the stuff in WM_CREATE at all.
