今天重头开始学学vc，，写个windows入门的程序

WinMain.cpp

`````````````

 

#include <windows.h>

#include <stdio.h>

 

LRESULT CALLBACK WinSunProc(

HWND hwnd, //handle to windows

UINT uMsg, //message identifier

WPARAM wParam, //first message parameter

LPARAM lParam //second message parameter

);

 

int WINAPI WinMain(HINSTANCE hInstance, //handle to current instance

  HINSTANCE hPreInstance, //handle to previous instance

  LPSTR lpCmdLine, //command line

  int nShowCmd //show state

)

{

//设计一个窗口类

RegisterClass(&wndcls);

 

//创建窗口，定义一个变量保存成功创建窗口后返回的句柄

HWND hwnd;

hwnd=CreateWindow("2010","biaoti",WS_OVERLAPPEDWINDOW,0,0,600,400,NULL,NULL,hInstance,NULL);

 

//显示及刷新窗口

ShowWindow(hwnd,SW_SHOWNORMAL);

UpdateWindow(hwnd);

 

//定义消息结构体，开始消息循环

MSG msg;

while (GetMessage(&msg,hwnd,0,0))

{
