Does not execute it for which reason?

[abdul]

I have written the following code to create a simple window. But the problem is that whenever I click execute button. It does not execute(run) it. It does nothing.

Please Note:

I am using Visual C++ 6 Enterprise, and every other program is executed except this one. I also copied and pasted the code from www.winpro.org to create a simple window and it works fine. Please find any error if you can.

#include <windows.h>
static char myclass[] = "t";
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wparam, LPARAM lparam)
{
	switch(msg)
	{
	case WM_CLOSE:
		DestroyWindow(hwnd);
		break;
	case WM_DESTROY:
		PostQuitMessage(0);
		break;
	default:
		return WndProc(hwnd, msg, wparam, lparam);
	}
	return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
	WNDCLASSEX wc;
	MSG message;
	HWND hwnd;

	wc.cbClsExtra = 0;
	wc.cbWndExtra = 0;
	wc.hbrBackground = (HBRUSH) GetStockObject(GRAY_BRUSH);
	wc.hCursor = LoadCursor(NULL, IDC_ARROW);
	wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
	wc.hInstance = hInstance;
	wc.lpfnWndProc = WndProc;
	wc.lpszMenuName = myclass;
	wc.lpszMenuName = NULL;
	wc.style = NULL;
   

	if(!RegisterClassEx(&wc))
	{
		return 0;
	}

	hwnd = CreateWindowEx(
			WS_EX_CLIENTEDGE,
			myclass,
			"This is win",
			WS_OVERLAPPEDWINDOW,
			0,
			0,
			100,
			100,
			NULL,
			NULL,
			hInstance,
			NULL);
	if(hwnd == NULL)
	{
		return 0;
	}

	ShowWindow(hwnd, nShowCmd);
	UpdateWindow(hwnd);

	while(GetMessage(&message, NULL, 0,0))
	{
		TranslateMessage(&message);
		DispatchMessage(&message);
	}

	return message.wParam;
}

Thanks!
