Hello,
I'm trying to make an graphic user interface for an app running in dos mode; This app (programmed in c) send messages using the PostMessage API.
I cant call this app and tell it to send the message to my GUI by putting a GetForegroundWindow in the command line, but how can I get back those messages. I tried PeekMessage but I always obtain a message the text (MyMessage.message) of which is 512.

So, what did I do wrong ?
Thanks for any help.
