关于弹出消息窗口的自动关闭_pb messageboxtimeout-优快云博客

本文介绍两种在Windows环境下实现自动关闭消息对话框的方法。方法一通过直接在代码中添加MessageBoxTimeout函数，该函数允许设置对话框自动关闭的时间。方法二则通过调用微软未公开的API，同样实现了定时自动关闭对话框的功能。文章提供了详细的代码示例和调用方式。

1.方法1

1.1. 直接在代码中添加


 
 
   
   
    
    
   
   
   
   
    
    
     
     // 弹出消息窗口自动关闭，需要指出的是，Windows 2000的user32.dll没有导出这个函数。
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     extern 
     
     "C"
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     {
    
    
   
   

   
   
    
    
   
   
   
   
    
        
     
     int WINAPI MessageBoxTimeoutA(IN HWND hWnd, IN LPCSTR lpText, IN LPCSTR lpCaption, IN UINT uType, IN WORD wLanguageId, IN DWORD dwMilliseconds);
    
    
   
   

   
   
    
    
   
   
   
   
    
        
     
     int WINAPI MessageBoxTimeoutW(IN HWND hWnd, IN LPCWSTR lpText, IN LPCWSTR lpCaption, IN UINT uType, IN WORD wLanguageId, IN DWORD dwMilliseconds);
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     };
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     #ifdef UNICODE
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     #define MessageBoxTimeout MessageBoxTimeoutW
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     #else
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     #define MessageBoxTimeout MessageBoxTimeoutA
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
     #endif

1.2. 调用


 
 
   
   
    
    
   
   
   
   
    
    
     
         MessageBoxTimeout(
     
     this->GetSafeHwnd(), _T(
     
     "弹出5秒后会自动关闭！这是一个模态对话框。"), _T(
     
     "会自动关闭的MessageBox"),  MB_ICONINFORMATION, GetSystemDefaultLangID(), 
     
     5000);
    
    
   
   

   
   
    
    
   
   
   
   
    
        
     
     //参数说明：父窗口的句柄为NULL的情况下，将弹出非模态对话框；延时关闭的时间为0的情况下，弹出的MessageBox需要手动关闭
    
    
   
   

   
   
    
    
   
   
   
   
    
    
     
         MessageBoxTimeout(
     
     NULL, _T(
     
     "弹出5秒后会自动关闭！这是一个非模态对话框。"), _T(
     
     "会自动关闭的MessageBox"),  MB_ICONINFORMATION, GetSystemDefaultLangID(), 
     
     5000);

2.方法2

2.1.此api是微软的一个未公开api，在user32.dll中，功能就是弹出一个对话框MessageBox，并定时自动退出。
下面为头文件，随便取个名字，我取的是MsgBoxTimeout.h 。
