如何在后台修复窗口？

Question

I want to make that window doesn't become foreground while execute postmessage(). But, while execute program, window become foreground.

point = (x,y);
lParam = makePararm(x,y);
PostMessage(hWnd, WM_LBUTTONDOWN, MK_LBUTTON, lParam);
sleep(0.03);
PostMessage(hWnd, WM_LBUTTONUP, MK_LBUTTON, lParam);

This program is that click x,y. I want to click window in background (not become foreground!) Could someone please help?

Answer 1

You are sending a mouse message to the window, as if the user is clicking the mouse. The receiving application cannot differentiate between this, it just thinks you clicked it with the mouse and so it decides to get activated.

When the application you send the message to is yours (and you have the source of it), you can let it handle a custom message and send that message instead.

Now you are just simulating a mouse click.
