>I have a scenario where I need to send misc. windows messages including an array of data from a VFP 5 application to a Delphi 3 app. I couldn't find any info in the VFP online docs. Has anyone done this before? Do I use Win32API calls to complete this?

You can but it's difficult. First you should consider if you can build
a VFP COM object and call that from Delphi - that'll be the easiest
way, but it'll limit you synchronous operation.

If you need asynchronous, the easiest thing I can think of is to use
message files that are sent to communicate the data and results. The
client sends a request file, the server picks it up and then returns
a result file, which the client in turn picks up.

There's lots of different ways to do the above scenario from using
queue files to using a sophisticated solution like MS Message Queue
to handle the queuing and assignment of jobs.
