Hey, thanks for answering!  I'm getting desperate about this problem;
it's one of two that are keeping me from getting my application done.

Alas, I misinformed you.  I do indeed use PostMessage(), with the same
lack of results.

Lately, I've tried both SetFocus() (before sending the messages) and
WaitMessage() (between the KEYDOWN and KEYUP messages) to see if I was
hogging any resources and preventing the other application from
processing my messages.  No improvement.

Why in the heck does SDKHelp work and all these others don't??????  A
possible hint is, the keystroke I'm sending SDKHelp is F1, while all
the other attempts have been control-characters (requiring two
messages...).  I've used Spy again and tried to get my messages to
appear *exactly* as the actual keystrokes, but there's only so much
I've been able to accomplish to that end.

Again, thanks for the input.
