displaing saved views
using code below from sample that will display view but it does not work, my display stays the same.
in the sample app, how is the screen told to re-paint pls ?.
oddbobjectid tablid = m_pdatabase->getviewtableid();
oddbviewtableptr tablptr = tablid.safeopenobject(oddb::kforread);
odstring strviewname = "view to display";
oddbobjectid viewid = tablptr->getat(strviewname, true);
oddbviewtablerecordptr vtablrec = viewid.openobject();
if(vtablrec.get())
{
oddbobjectptr pvpobj = activeviewport(m_pdatabase).safeopenobject(oddb::k forwrite);
if ( pvpobj.isnull() )
{
oddbabstractviewportdataptr pvppe( pvpobj );
pvppe->setview(pvpobj, vtablrec);
pvppe->setucs(pvpobj, vtablrec);
pvppe->setprops(pvpobj, vtablrec);
odstring slsname = vtablrec->getlayerstate();
if(!slsname.isempty())
{
oddblayerstate::restore(m_pdatabase, slsname,
oddblayerstate::kundefdonothing, oddblayerstate::kon|oddblayerstate::kfrozen);
}
}
}

in odamfcapp sample it is done this way:
code:
m_pdevice->invalidate();
redrawwindow();
sincerely yours,
