app = new          


        

Answer 1

For a single click you should send two mouse event at the same time for an exact mouse click event.

SendMessage(nChildHandle, 0x201, 0, 0); //Mouse left down
SendMessage(nChildHandle, 0x202, 0, 0); //Mouse left up

It is working in my project.

Answer 2

Save the cursor position, use mouse_event and move the cursor back. mouse_event is really the best way to do this.
