     Need to communicate between two or more .EXE apps, then this is one easy way to do it. Just include the frmDDEClient in your main app and frmDDEServer in your other app and hook up the code properties and Event of those forms in their respective app. DDE Communications is built into VB6 and this sample code provided here shows how to do probably all of what you want to do. There are two apps included: The Main or Client app and the Server App (some like to call it Source but to me that is confusing). My naming convention may fly in the face of other Internet information but this is how I see it. You must compile the Server app to use it. You can run the Client app in the IDE or compile it and run it as an .EXE. I hopefully commented this source code sufficiently so that it can be understandable to even the newbie. All the stuff I have found on the Internet is way too vague about how each Link parameter relates to either the Client or the Server. Hope this submission clears it up.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net
