2 applications</DIV>
<DIV><BR></DIV>
<DIV>Hello Group,</DIV>
<DIV> </DIV>
<DIV>I have 2 (related) questions on this subject...</DIV>
<DIV> </DIV>
<DIV>Question 1: If another application (it's not Access, I believe it's
C++) uses the Shell command to launch my Access application, and the
Access app is already open, will this simply make the Access app "active",
or will it launch a 2nd instance of it? (I'm wanting it to make my
app active, not open another copy.)</DIV>
<DIV> </DIV>
<DIV>Question 2: Is there any kind of "Application.Activation" event I can
hook into? If the above issue can be resolved to activate the Access
app, I need Access to go to a specific form and process a small amount of
data from the launching application. (I can do this if the other app
actually opens the Access app, but am not sure if I can call this
processing routine when the already-open app is activated.)</DIV>
<DIV> </DIV>
<DIV>Thanks in advance for any direction you can provide.</DIV>
<DIV> </DIV>
<DIV>Best Regards,</DIV>
<DIV> </DIV>
