Activate window inside a VM from Host

Hi,

I'm running a script from Host and want to control a window insde a virtual machine, using VMware Player.

Mouseclick, everything works, except for the screen coordinates and pixel coordinates...

If i make the mouse click at 0,0 it always clicks on the top let corner of the virtual machine, not the activated window inside of it. I tried WinActivate on Notepad to test, no joy.

I tried with all these options :

Sets the way coords are used in the mouse functions, either absolute coords or coords relative to the current active window:
0 = relative coords to the active window
1 = absolute screen coordinates (default)
2 = relative coords to the client area of the active window

Waiting for some help!

Thank you.
