MessageBeep - Play a System sound

There is a interesting function which can play a System sound.

First let's see the WinAPI.

//声明:

MessageBeep(

  uType: UINT {参数是个常数; 根据不同的常数发出不同的声音, 也就是调用了不同的 wav}

): BOOL;            



//参数 uType 可选值:

MB_OK              = 0;

MB_ICONHAND        = 16;

MB_ICONQUESTION    = 32;

MB_ICONEXCLAMATION = 48;

MB_ICONASTERISK    = 64;





//举例, 下面代码会发出错误警告

begin

  MessageBeep(16);

end;





//另外 Delphi 的 Beep 方法在 SysUtils 单元是这样实现的:

procedure Beep;

begin

  MessageBeep(0);

end;

If you wana beep in your console program. You can use it like following.

 1 #include <Windows.h>

 2 

 3 int _tmain(int argc, _TCHAR* argv[])

 4 {

 5     for( UINT i = 0; i < 100; i ++) {

 6         MessageBeep(i);

 7         Sleep(1000);

 8     }

 9     return 0;

10 }

Well, Running it, it will beep differently in every second. Thank you!
