Send Click Message to another application process

Question

I have a scenario, i need to send click events to an independent application. I started that application with the following code.

private Process app;
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.
