Hi
You're in luck. Just a few weeks ago I created VI's to read and write memory
mapped files!
I've tested it with interaction between several LV applications (.exe) and
mixed it with several instances of LV, and that worked fine (see thread
"Communitating Between Built LV App.s"). The VI's are there to download.
The difficult part is to get LV to write into memory. If you only want to
write a string, it's easy, but for data (with \00 in it) it's a bit more
difficult. Anyway, the VI's already have that functionality.
The VI's are written to interact between LV applications, but everything to
interact with other applications is in there. Perhaps some things turn up,
but I'm sure they are all solvable.
Regards,
Wiebe.
