oddbdatabase::insert
oddbdatabase::insert
hi
i want to insert several drawings into one target drawing. the code looks like:
code:
odstaticrxobject<myservices> *svcs = new odstaticrxobject<myservices>();
odinitialize(svcs);
...
// created this and already added some entities
oddbdatabaseptr targetdb = ...;
// srcfiles is an array containing all (3 in this simple case) src file names
for (int i=0; i<3; i++) {
oddbdatabaseptr srcdb = svcs->readfile(srcfiles[i]);
targetdb->insert(/* some block name */, srcdb);
}
odwrfilebuf filebuffer(targetfilename);
targetdb->writefile(&filebuffer, oddb::kdwg, oddb::vac18);
oduninitialize();
the writefile call fails with a "zugriffsverletzung-leseposition 0x013659d4" (freely translated 'accessviolation-address'). below is the stack trace.
code:
tbdwgbuilder.dll!odobjectdwgoutstream::wrsoftpointerid() + 0x16 c++
tbdwgbuilder.dll!oddbobject::dwgoutfields() + 0x13c c++
tbdwgbuilder.dll!oddbentity::dwgoutfields() + 0x2b c++

tbdwgbuilder.dll!oddwgr18filewriter::writedatabase() + 0xb7 c++
tbdwgbuilder.dll!oddbdatabase::writefile() + 0x5eb c++
i did a very simple application that inserts one dwg into a target dwg and this simple example worked. so it might be that nothing is wrong with the code.
what else could be wrong? do i miss to initialize everything properly?
i'm using visual studio .net 2003 on windows xp, just in case that this matters.

oddbdatabase:insert problem (additional information)
ok, i created a simple test program (see below) that fails with the described exception (see my last post). can anybody tell me what's wrong with the code? another interesting point: if i omit the for loop it works!!! i'm sure i'm just missing something.
any help?

hi,
the code seems ok. i tested on vs6, win2000 (i don not think that .net is the cause).
what version of ddt do you use? if it is the last one, could you send me a file that produces crash?
best regards,
sergey
hi,
i have the same problem. what is ddt?
dwgdirect toolkit
