Hi Sameh,

I made today this sample for John Crouse, do you think you can do something
with it?

P/invoke on 'mouse_event'.

What's P/ ?

P/invoke is about calling platform functions ("Windows API") in .NET.

can you please a simple example

I feel sorry, I currently don't have a .NET sample. A VB6 sample can be
found here:

hey Cor
Thank for answering
this is close, but my problem is sending a click out of the form
I want to provide coordinates and emulate a mouse click there.
Regards
Sameh
