I’ve been having issues with PTCGraph causing a runtime Error 217 :
EAccessViolation: Access violation at seemingly random times in my

PutImage() but not the same one.The program can run for hours with no
problems doing GetImage and PutImage every second or so, and then it
just stops with this error.
I know that if something disrupts the screen… like if I install a
program and the Windows user control thing asks for a password, that
ALWAYS causes this to happen, or if I unplug my monitor and plug it
back in…. I find that this happens.. but lately it seems to happen for
no reason.
I don’t know enough about it to track it down, but is there some way I
Can find out what causes this and prevent the error?It would be nice
if I could detect the condition that causes this issue, and if I find
that the issues is present, just stop trying to do Getimage() or
PutImage() until the condition is resolved.
Can you provide an example program and exact steps to reproduce this bug?
