c++ 创建Windows窗口

直接上代码，附注释：

#include 


 
LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam) {
	switch(Message) {
		
		
		case WM_DESTROY: {
			PostQuitMessage(0);
			break;
		}
		
		
		default:
			return DefWindowProc(hwnd, Message, wParam, lParam);
	}
	return 0;
}


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

	
	memset(&wc,0,sizeof(wc));
	wc.cbSize		 = sizeof(WNDCLASSEX);
	wc.lpfnWndProc	 = WndProc; 
	wc.hInstance	 = hInstance;
	wc.hCursor		 = LoadCursor(NULL, IDC_ARROW);
	
	
	wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
	wc.lpszClassName = "WindowClass";
	wc.hIcon		 = LoadIcon(NULL, IDI_APPLICATION); 
	wc.hIconSm		 = LoadIcon(NULL, IDI_APPLICATION); 

	if(!RegisterClassEx(&wc)) {
		MessageBox(NULL, "Window Registration Failed!","Error!",MB_ICONEXCLAMATION|MB_OK);
		return 0;
	}

	hwnd = CreateWindowEx(WS_EX_CLIENTEDGE,"WindowClass","SB",WS_VISIBLE|WS_OVERLAPPEDWINDOW,
		CW_USEDEFAULT, 
		CW_USEDEFAULT, 
		640, 
		480, 
		NULL,NULL,hInstance,NULL);

	if(hwnd == NULL) {
		MessageBox(NULL, "Window Creation Failed!","Error!",MB_ICONEXCLAMATION|MB_OK);
		return 0;
	}

	
	while(GetMessage(&msg, NULL, 0, 0) > 0) { 
		TranslateMessage(&msg); 
		DispatchMessage(&msg); 
	}
	return msg.wParam;
}
