Simulate Mouse move / clic from a C++ app

[Benoît Touron]

Hello there !

How can I simulate a mouse move, and then clic from a C++ app ?

I have an external app, with a graphical area. I need to move the mouse
to a specific location within this window, then clic and enter some text.
The goal is to drive this external app from my own app.

I have the handle of the main window, but I am not able to move the
mouse with a program.
Does anyone know how to do this ? Which system call do I have to use ?

Thanks
Ben

I haven't tried it, but did you look at the SetCursorPos() function??

Thanks Bjarne.
It works ! But I am still not able to simulate a mouse clic
in a specific location ot the windows client area.
I tried the following:

HWND other=::FindWindow(NULL,"CHILD WINDOW");

::SetWindowPos(other,HWND_TOPMOST,0,0,0,0,SWP_NOSIZE|SWP_SHOWWINDOW);
SetCursorPos(10,10);

::SendMessage(other,WM_LBUTTONDOWN,MK_LBUTTON,0x0A0A);
::SendMessage(other,WM_LBUTTONUP,MK_LBUTTON,0x0A0A);

The window actually moves to the top left corner of the screen. This
should pop-up the system menu (because the mouse is at the right
location), but nothing happens.

Any other (good) idea ?

Thanks a lot anyway.

Like I mentioned before, I haven't really done this before. I did something
similar once, but that code is gone now :-(
I think the position parameters are wrong, though. The LPARAM should contain
the X and Y coordinates in low and high order WORDs, but you packed then
together as two BYTEs in one WORD, so I gues it should be 0x000a000a
instead, or more correctly MAKELPARAM(0x0a, 0x0a).
Also, you shouldn't hard-code the coordinates (as you probably know), but
for testing it's ok.
