本文详细介绍了如何利用C++与Windows API来创建并管理Win32应用程序的基本窗口，涵盖了从初始化实例到消息循环的全过程。

#include "stdafx.h"
#include <windows.h>
#include <WinUser.h>
//窗口过程函数 
LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam); 


int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
 	


	HWND         hWnd;         //主窗口句柄
	HINSTANCE    hInst;        //实列句柄


	MSG sMsg;   //过程消息结构
	WNDCLASSEX sWndClassEx;//类结构
	hInst = hInstance; 




	sWndClassEx.cbSize = sizeof(WNDCLASSEX); 
	sWndClassEx.style = CS_VREDRAW | CS_HREDRAW; 
	sWndClassEx.lpfnWndProc = (WNDPROC) WndProc; 
	sWndClassEx.cbClsExtra = 0; 
	sWndClassEx.cbWndExtra = 0; 
	sWndClassEx.hInstance = hInst; 
	sWndClassEx.hIcon = LoadIcon(NULL, IDI_APPLICATION); 
	sWndClassEx.hCursor = LoadCursor(NULL, IDC_ARROW); 
	sWndClassEx.hbrBackground = (HBRUSH) (COLOR_WINDOW); 
	sWndClassEx.lpszMenuName = NULL; 
	sWndClassEx.lpszClassNam
