Hi all,
I've just been given responsibility for a client server system
which communicates via NetDDE. The client is written in VB and
the server is written in VBA/Access. The client is typically
executed from another process, which then carries on regardless.
I've got two problems:
1) If the original calling process goes on to print a document
(using dos based printing methods) the client app hangs until the
print finishes even though they're completely different processes.
2) If the calling program attempts to wait for the client to finish
both programs hang.
Has anyone got any ideas? Is VB doing something wierd like using the
calling processes window for its DDE messages or something?
Ta,
Paul
