Displaying JPG images

[Bob Rasmussen]

To summarize, I believe you want to:

1. Restrict to one instance of the viewer application.

2. Have that app always appear in the same place.

3. Have filePro retain (or regain) "focus", that is, be the active program
that keystrokes go to.

The last one is going to be the most difficult. If you have to run a
command to start a different program in Windows each time, neither that
program nor Windows will shift focus back to filePro. Does filePro have
access to the Windows API SetFocus call? Ken?

The first two will depend greatly on the program you use as your viewer.
You might want something that is targeted as an "image enabling" program.
You might also want to look at the "Microsoft Office Document Imaging"
program.

One way to solve the first two issues would be to have a program running
(just one instance), and to tell it to change which picture it is
displaying. This is done through some sort of inter-application-control
(IAC). The usual mechanisms are DDE (quite old) and OLE/COM. The question
is, does the filePro runtime support any of these?
