Hi,
I'm creating a program that will have plugin support but there is still hurdle to cross. I want each plugin to be able to send message or command to the Parent application as well as recieve commands from the Parent. I was hopin that I could create a control on the Main form of the Parent Application and then subclass it so that I can track all messages that are been sent to it.

Now, my question is how do I send a message(command) from another application to a textbox on the Parent application?

If have any ideas or suggestions please let me know. I've got everything else to work except this.
