在外部应用程序中捕获按钮的单击事件

Question

I would like to know whether a button in an external app is clicked. Before I had to do the clicking myself, for which I used the following code:

//Get window
IntPtr wrapUp = Win32API.FindWindowByText(Win32API.GetDesktopWindow(), "WRAP-UP");
if ((int)wrapUp > 0)
{
    Win32API.SetFocus(wrapUp);
    IntPtr okButton = Win32API.FindWindowByText(wrapUp, "OK");
    Win32API.SetFocus(okButton);
    Win32API.PostMessage(okButton, Win32API.BM_CLICK, 0, 0);
}

But now I need to know when the user clicks that button. Is there a way to do this?

I've been searching a bit and I've found several ways to perform the clicking from code, but not for listening to an event.

您可以使用SetWinEventHook设置事件挂钩函数，并收听EVENT_OBJECT_INVOKED ，该事件指示已调用对象（例如，单击了按钮）。
