Run time error in WinMain() function.

[clisen]

Hey there, I'm setting up a default program to use as a template for my future DirectX applications. The program compiled fine but I'm getting a run time error in my WinMain() function.

Here is the WinMain() function.

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE prev, 
				   LPSTR cmd, int show) {
	
	MSG msg;

	// Describes a window
	WNDCLASSEX windowClass;
	memset(&windowClass, 0 ,sizeof(WNDCLASSEX));
	windowClass.cbSize = sizeof(WNDCLASSEX);
	windowClass.style = CS_HREDRAW | CS_VREDRAW;
	windowClass.lpfnWndProc = WndProc;
	windowClass.hInstance = hInstance;
	windowClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
	windowClass.hCursor = LoadCursor(NULL, IDC_ARROW);
	windowClass.lpszClassName = "DX10CLASS";
	windowClass.hIconSm = LoadIcon(NULL, IDI_APPLICATION);

	if(!RegisterClassEx(&windowClass)) return 0;

	//Create window
	HWND hwnd = CreateWindowEx(NULL, "DX10CLASS", WINDOW_NAME,
							   WS_OVERLAPPEDWINDOW | WS_VISIBLE | WS_SYSMENU |
							   WS_CLIPCHILDREN | WS_CLIPSIBLINGS, 100, 100, 
							   WINDOW_WIDTH, WINDOW_HEIGHT, 0, 0, hInstance, NULL);

	if(!hwnd) return 0;

	ShowWindow(hwnd, SW_SHOW);
	UpdateWindow(hwnd);


	//If initialize fails don't run the program.
	if(InitializeD3D10(hwnd) == true) {
		if(Initialize() == true) {
			
			while(1) {
				if(PeekMessage(&msg, 0, 0, 0, PM_REMOVE)) {
					if(msg.message == WM_QUIT) break;
					TranslateMessage(&msg);
					DispatchMessage(&msg);
				}
				else {
					Update();
					RenderScene();
				}
			}
		}
	}

	Shutdown();
	UnregisterClass("DX10CLASS", windowClass.hInstance);

	return msg.wParam;
}

And this is the run time error:
Run-Time Check Failure #3 - The variable 'msg' is being used without being initialized.

Not sure why it is saying it is not initialized, I have never had this happen before unless I'm missing something that I'm not seeing.

Any advice is welcomed.
