There is a interesting function which can play a System sound.
First let's see the WinAPI.
代码语言：javascript复制//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.
代码语言：javascript复制 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!
