MessageBeep - Play a System sound

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

First let's see the WinAPI.

//聲明:
MessageBeep(
  uType: UINT {參數是個常數; 根據不一樣的常數發出不一樣的聲音, 也就是調用了不一樣的 wav}
): BOOL;            

//參數 uType 可選值:
MB_OK              = 0;
MB_ICONHAND        = 16;
MB_ICONQUESTION    = 32;
MB_ICONEXCLAMATION = 48;
MB_ICONASTERISK    = 64;


//舉例, 下面代碼會發出錯誤警告
begin
  MessageBeep(16);
end;


//另外 Delphi 的 Beep 方法在 SysUtils 單元是這樣實現的:
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!
