helloworld程序

#include<windows.h>  
      
    int WINAPI WinMain(  
            HINSTANCE hInstance,  
            HINSTANCE hPrevInstance,   
            PSTR szCmdLine, int iCmdShow )  
    {  
        MessageBox( NULL, TEXT("Hello,world!"), TEXT("显示"), 0 );//0和MB_OK功能一样，都是出现一个确定按钮  
      
        return 0;  
    }

编写windows程序要包含在windows.h头文件中

MessageBow()函数  用于对话框的创建显示和操作

原型 ：int WINAPI MessageBox( HWND hWnd, LPCTSTR lpText, LPCTSTR lpCaption, UINT uType );

hWnd : 此参数若为NULL，则消息框没有父窗口，比如helloworld程序只有一个窗口

lpText: 消息框的内容

lpCaption: 消息框的标题

uType: 按钮设置
