regeneration of gsmodel causes exception in update
regeneration of gsmodel causes exception in update
hi,
i have a problem when i try to regenerate the display in order to draw arcs more precise on screen. after the regeneration the update call throws an exception. if i don't call regen() before paint() (see below) the view is rendered ok. i have tried to browse the call stack and it seems it has something to do with rendering true type fonts?
i am using version 1.13
thanks in advance,
stefan hestner
code:
void cadview::init()
{
odgsmoduleptr pgs = :drxdynamiclinker()->loadmodule("wingdi");
odgsdeviceptr pdevice = pgs->createdevice();
enablegsmodel(true);
...
mpdevice = oddbgsmanager::setupactivelayoutviews(pdevice, this);
}
void cadview::regen()
{
mpdevice->invalidate();
if(mpdevice->gsmodel())
mpdevice->gsmodel()->invalidate(odgsmodel::kinvalidateall);
}
void cadview:aint()
{
try {
mpdevice->update();
}
catch(...) {
<- ends up here if regen has been called
}
}

dear stephan,
is it possible to reproduce the problem in our odamfcapp sample?
could you attach the dwg file that is enough for reproducing the issue in our odamfcapp sample?
sincerely yours,
george udov
no, i don't get the same problem in odamfcapp. so i must do something wrong, but i can't find out what it is. everything else works fine until i call regen. i'm not using the doc-view model so the structure of my code is slightly different from the one in odamfcapp. not all dwg files causes the exception.
/stefan
which exception do you get? oderror? what is error code? what exactly are you seeing in the stack?
sincerely yours,
george udov
i get an access violation. i've included the call stack below.

sorry to drag up an old post, but we have a dwg file that shows exactly the same problem. we also cannot reproduce in odamfcapp. we are still on 1.13.
stefan,
if you are still around, did you ever find a solution to your problem?
thanks.
