trouble with 1.14 setsnapincrement
i'm upgrading my program from 1.12 to 1.14, and a call to oddbviewport::setsnapincrement() that used to work is now throwing an exception:
stdmethodimp ccaddata::addviewport(double dllx, double dlly, double durx, double dury, double dviewcenterx, double dviewcentery, double dscale)
{
afx_manage_state(afxgetstaticmodulestate())
assert(!m_pdb.isnull());
oddbblocktablerecordptr pps = m_pdb->getpaperspaceid().safeopenobject(oddb::kforwrite) ;
oddbviewportptr pvp = oddbviewport::createobject();
pvp->setcenterpoint(odgepoint3d((durx+dllx)/2.0, (dury+dlly)/2.0, 0.0));
pvp->setwidth(durx-dllx);
pvp->setheight(dury-dlly);
pvp->setviewtarget(odgepoint3d(0.0, 0.0, 0.0));
pvp->setviewdirection(odgevector3d(0.0, 0.0, 1.0));
pvp->setviewheight(dscale);
pvp->setlenslength(50.0);
pvp->setviewcenter(odgepoint2d(dviewcenterx, dviewcentery));
pvp->setsnapincrement(odgevector2d(0.0, 0.5));
pvp->setgridincrement(odgevector2d(0.0, 0.5));
pvp->setcirclesides(oduint16(100));
pps->appendoddbentity(pvp);
return s_ok;
}
any idea why?
snap increment must be positive and non-zero.

thanks...
thanks... i pulled that line from an earlier version of examples\odwriteex\dbfiller.cpp. i see that the version 1.14 example has now changed.
