I want to be able to send data from one program to another with SendMessage and GetMessage (in the user message range from &h0400 to &h7fff). The problem is on the receiving end, GetMessage "blocks" so that the program locks up whenever it is not receiving a message. And the problem with the alternative PeekMessage (which isn't a "blocking" function) is it doesn't catch every message sent (so it might miss a very important piece of data if the one it missed was this important piece of data). Please help here. Thanks in advance.
