Prowin32 return code

Luc,

I've had the need to do the same thing, but since I havent found any way to
return values from progress, I have had to resort to using a temporary file
on disk to return values to visual basic.

Subject: [Vantage] Prowin32 return code


Hi all,

I'm currently writing VB code that calls Prowin32 to execute some 4GL code.

I'd like to be able to return an exit code from my progress code. At this
point, I can execute and get return code for any executable from VB, so I'm
only missing the prowin32/progress bit.

Looking at the progress docs, I haven't been able to find relevant
information, so if anyone can push in the right direction... :-)

Many thanks,

The RETURN statement can return a value to the calling routine in
Progress but not to Visual Basic. It could be done with Windows API
routines but here are some simpler methods:

1. Have the Progress program write out the information to a file for
VB to read.

2. Use the clipboard if no other program and user is using it at the
same time:

Progress: clipboard:value = returnvalue.
VB: returnvalue = clipboard.gettext

3. Break up your VB code into two pieces:

vbcode1: shell "prowin32.exe -p pcode.p"
pcode.p: dos silent value("vbcode2.exe " + returnvalue).
vbcode2: returnvalue = command$
