Can i use global mouse hook to detect if application A has been clicked by a mouse from a monitoring application B?

when Application A is clicked by mouse you should send a window message to application B it includes finding the window of application B and P/Invoking for sending the message(for finding the handle use Process.GetProcesses)

then in application B implement IMessageFilter to catch the windowmessage and raise an event(implementing IMessageFilter).
