请问 IdleLib.dll 已经失效了么?

下载了 IdleLib.dll 拦按键信息,

但是没有任何信息出现,

难道这个库已经不能使用了?

我的测试代码如下:

void vHandsTrade_CheckKey()
{

static int pre_time = 0;

int i, now_pressed = GetLastKeyWP();
string name, lastwnd = GetActiveWndName();

Comment( StringConcatenate( "check_key(): now_pressed = ", now_pressed, ", lastwnd = ", lastwnd ) );
if( now_pressed != 0 && lastwnd != "" )
{
Print("wnd:",lastwnd," key:",now_pressed);
}

}
