C# Send Mouseclick to Window

P: 39
Is there a way to send mouseclick to an inactive window? My guess would be to use the Win32 API function PostMessge(). I tried to do this and it seems like that it may be sending the mouse click but I think the coordinates are with respect to the top left of the desktop and not the top left of the hWnd that I send as a parameter.

I think you might be correct?
You will probably have to dig around for functions that tell you were the window is and do some conversions then?

Can you devise a test setup to find out what itse doing?
Perhaps make a program with a single form that registers mouse clicks and displays their coordinates.
Then you could post your click message to it and see where it thinks the mouse is clicking?

So apparently the coordinates that you supply in PostMessage() are with respect to the hWnd that you also supply. I just was supplying bad coordinates for the click because of a typo.
