[ProgSoc] Windows thread communication?

[Geoff Saxby <geoffs@nospam.progsoc.uts.edu.au>]

Hi y'all

I'm trying to get two threads to communicate in Windows <SHUDDER>. I'm
using PostThreadMessage in one thread and PeekMessage in the other
thread.  PostThreadMessage fails and GetLastError() returns 1159:
ERROR_MESSAGE_SYNC_ONLY which MSDN tells me means the message can only
be used with synchronous operations. What does this mean? I thought
that PostThreadMessage allowed asynchronous communication between
threads. Any ideas why this happens? Or how else can I send a message
from one thread to the other without the first thread blocking?

BTW, I'm using Borland C++ Builder 5 Enterprise. Problem is the same on
Windows 98 and 2000.

TIA
Geoff
