推荐答案

如果这是子进程中的按钮，则只能使用P/Invoked Windows API模拟使用输入，例如鼠标单击SendInput: http://msdn.microsoft.com /en-us/library/windows/desktop/ms646310%28v=vs.85%29.aspx [ http://pinvoke.net/default.aspx/user32.sendinput [

If this is a button in a child process, you can only simulate a use input like a mouse click, using P/Invoked Windows API SendInput: http://msdn.microsoft.com/en-us/library/windows/desktop/ms646310%28v=vs.85%29.aspx[^], http://pinvoke.net/default.aspx/user32.sendinput[^]. Remember, the processes are well isolated. You cannot effectively control a foreign process unless it is specially designed for accessibility from another process.

Look, if I understand you right and you want to control a child process, let me tell you: you are solving a bad problem. This is pretty much useless and hardly can be reliable. This will not integrate a process in your application.
