Hi Remy - Thanks for the info - I almost follow you -

I understand the part about the application sending custom msg, and the dll
hook function intercepting that message.

That would at least tell the dll that the application->control is active to
receive messages (edit boxes receiving key messages, etc).

Is there anyway for the dll hook function to distinguish which of many
controls a particular message is coming from?

For example - the edit box I want to record info from could receive a msg,
then the user goes to another box, then jumps back to the box I'm interested
in, the recording seems to get jumbled up - which box was a particular key
stroke message  intended for?

I know I  missing something still - but its a little clearer.

Thanks very much,
CurtC
