how to hide a layer?
hi all,
i'm trying to implement hide/show function for dwg layers in a dwg file.
i can get the list of the layer in layer table, but when i try to set the property i get an assertion error.
my "temp" code is this:
code:
mdbptr = mhostappserv.readfile( infile.c_str(), false, false );
if( !mdbptr.isnull() )
{
// layer table smart pointer, opened for read.
oddblayertableptr players =
mdbptr->getlayertableid().safeopenobject();

oddbsymboltableiteratorptr piter = players->newiterator();

for (piter->start(); !piter->done(); piter->step())
{
// layer record smart pointer, opened for read.
oddblayertablerecordptr player =
piter->getrecordid().safeopenobject();
if( strcmp( lname.c_str(), "801d") == 0 ||
strcmp( lname.c_str(), "802d") == 0 )
{
player->setisoff( true );
}
}
is "isoff" the right property to be set?
do i open the dwg in right way?
thank you in advance for help
greetings
walter

i think you must set
safeopenobject(oddb::kforwrite)
because openmode default is oddb::kforread
may it be?
