Why not have process B send a message process A politely asking it to change
the checkbox? You can use .NET remoting for this purpose.

The checkbox belongs to process A, and process B shouldn't be making
assumptions about it.
 
thanks John Saunders
But i can use it in the other contorl such as button,edit,systreecontrol,and so on
why the checkbox could not respond the message for checkbox (BM_GETCHECK,BM_SETCHECK)
can anyone tell me about it

I'm sure you can use it in other controls, but that doesn't make it a good
idea. This is exactly the kind of hack you should try not to do in .NET.
