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.

#include <Windows.h>

int _tmain(int argc, _TCHAR* argv[])
{
    for( UINT i = 0; i < 100; i ++) {
        MessageBeep(i);
        Sleep(1000);
    }
    return 0;
}

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