You can use a file. App1 could write to it and App2 could read from it. In your App2 you can use a timer to read new data in the file in certain time period.

Or you could use the old method Dynamic Data Exchange. People say its old but it still works perfectly. Do a search on here for Dynamic Data Exchange, I've posted an example a while back. ;)

I attually think that the read and write Idea by jcis is proberly the easyest to make, it might be a bit messy but it could work really well if done right.

I did the same thing in fact, worked a treat :D

Moved from Classic VB.
