Hi guys,
I extracted the source code for VPCScreen, after having read it for an hour or
so I think the bug under linux is fixable.
The problem stems from a bunch of variables not being initialized in
vpcscreen_base_private that control the state of the vpcscreen_base class.
When the vpcscreen_base_private class is created its state variables are filled
with pretty much whatever random data happened to be in RAM before being used
by VPCScreen, thus causing a bunch of confusion.
In addition to fixing that by adding initialization code to the constructor for
vpcscreen_base (or private) I would also want to make some of the other code a
bit neater, and perhaps make it clearer which state the buttons should be in at
startup. I noted the menus aren't enabled and disabled the same way the buttons
are which creates potential crashes if a user clicks either one at the wrong
time.
I need to set up the build environment for VPCscreen to implement and test the
fix I have in mind, hopefully that won't be too hard. To be honest I'm
surprised this didn't cause a more serious issue in an older version.
As for running VPCScreen on a windows 7 machine, we are running it fine here on
one of our machines, and use it on a regular basis. What kind of symptom are
you getting? A crash? The start button greyed out (like the linux bug)? You can
run VPCScreen separately from the AG software via the command line much like
you can with vic, that will print errors out on the console that may help.
Otherwise the AG log would be a nice place to look.
You can run Vic and VPCScreen at the same time for transmitting on unicast,
I've done it on numerous occasions on windows XP. The technical reason for this
is due to how UDP works (the transport mechanism used in the AG with unicast).
It _should_ work on most other Os's as well.
Cheers
Andrew
