createdevice crashing
hello everyone,
i am very new to these forums. i have been looking over them the last few days trying to write a very simple app that will load a dwg file and then display it to a .net picturebox. i have all the dependencies worked out now. the problem i am having is that when i call 'device = pgs->createdevice();' my program crashes. i have looked through serveral examples that came with the dd_nonlibs. that is actually where i got that code from. from the singedoc example. if anyone could offer some help on this i would be very grateful.
code:
system::void form1::button1_click(system::object * sender, system::eventargs * e)
{
odgsdeviceptr device;
oddbdatabaseptr pdb;
bool binitserv = false;
oduint32 datalength = 0;
odbinarydata* thumbnail;
odrxobjectimpl<dwgservices> svcs;

try
{
odinitialize(&svcs);
binitserv = true;

odgsmoduleptr pgs = ::odrxdynamiclinker()->loadmodule("wingdi.gs");
device = pgs->createdevice();

//pdb = svcs.readfile("c:\\data\\building.dwg");
//pdb.release();
}
catch (oderror& e)
{
messagebox(null, "oderror", "oderror", mb_ok);
}
catch (...)
{
messagebox(null, "general error", "general error", mb_ok);
}
if(binitserv)
oduninitialize();
}

is pgs valid? i'd assume that it isn't loading the module as you expect.
it wasn't valid. but i add the macros below and now it loads.
#ifndef _toolkit_in_dll_
odrx_declare_static_module_entry_point(wingdimodul e);
#ifdef enable_acis_support
odrx_declare_static_module_entry_point(modelermodu le);
#endif
odrx_begin_static_module_map()
odrx_define_static_appmodule("wingdi.gs", wingdimodule)
#ifdef enable_acis_support
odrx_define_static_application("modelergeometry", modelermodule)
#endif
odrx_end_static_module_map()
#endif
