I cannot tell what you are doing wrong without more information. Can't you see what is happening by logging the IPC Read/Write data? That's what it is for, to help debug application programs. See the "Logging" page in the FSUIPC options.
If you do the logging and still can't see what you've got wrong, ZIP the log and attach it here and I'll take a look.
Sorry, I don't understand. What's a "hold filename"? Anyway, offset 3D00 contains the title of the current user aircraft, not the flight. The current flight is at 3F04, as documented in the Programmer's guide.

Thank you, I have made a mistake in the address of the flight.It's good now.
But I have not found a solution for the first problem:
My objective is intercept keyboard action in FS, then transmit it via the FSUIPC to an external program...What I do?
Thank's
