subject: VRF: Communication between two HPVEE applications
Hi all,
Just this question: What is suggested to be the best way for setting
up communication between two HPVEE programs on one machine.
I am thinking of one application which will do some
specific measurements. This will be used 'stand-alone' as well as in
an automated environment.
In the automated environment I want to 'drive' the same stand-alone
version to do many of these measurements in a kind of batchmode,
check the results, and eventually repeat some tests under operators
control or automatically.
To me the best approach seems to be to write this as two seperate
programs, because they are basically independent, and the batch-part
can easily be adapted to perform a similair task with other
measurements.
To get it working I need bi-directional communication, not that
difficult.
All this should run under NT 4.0 , VEE 4.01
I can think of :
- Calling the measurement as a function. But then
the handling of panels will become very tricky,
I think.
- Using files. Seems rather troublesome
to get it working bi-directional.
- Using Sockets. Just know not much about this.
- Using DDE, but I have some old communication about this,
which discourages me:

Any suggestions would be higly appreciated.

greatest solution but it will work. The project I am currently developing
involves socket communication and I've done alot of testing running both server
and client on the same machine. One thing though: A '486 of any flavour will
be hopelessly slow doing this unless both applications are fairly simple. Until
we have something like ARexx on the Amiga, DDE and Sockets are your only "in
memory" options.
