如何鼠标点击事件发送到隐藏的窗口？ [英] How to send a mouse click event to a hidden window?

问题描述

认识到可能需要互操作的一点，我怎么送鼠标点击事件当前没有显示的窗口？我有一个是作为服务运行和摆弄与隐藏窗口，需要鼠标点击事件发送到其中的一个，尽管它实际上并不能显示该窗口的应用程序。

Recognising that a bit of interop may be required, how do I send a mouse click event to a window that is currently not being displayed? I have an application that is running as a service and fiddling about with hidden windows and needs to send a mouse click event to one of them, even though it can't actually display the window.

正常的方式，我会做是简单地点击发送到屏幕在适当的位置，但很明显，这种方法不会在这种情况下工作。想法？

The normal way I would do it is to simply send a click to the screen in the appropriate location, but obviously that method won't work in this case. Ideas?

推荐答案

如果你能得到窗口的HWND，这是很容易。
使用 PostMessage的（）与 。WM_LBUTTONDOWN为左击

If you can get the HWND of the window, it's pretty easy. Use PostMessage() with WM_LBUTTONDOWN for a left click.

例如：点击位置10,10（未经测试，C）

Example: click on position 10,10 (untested, C)

HWND hWnd = (hwnd of window)
WORD mouseX = 10;
WORD mouseY = 10;
PostMessage(hWnd,WM_LBUTTONDOWN,0,MAKELPARAM(mouseX,mouseY));
