error opening some 2000/2004 files
error opening some 2000/2004 files
we recently upgraded from dgwdirect c++ (using visual studio 6) from 2.5 to 2.6, and we found that some dwg files 2000 and 2004 failed to import. to isolate the error, we tried to open them using the odamfcapp, and in the one using the dlls 2_05_06 it worked fine.
when using the newer application, with the dlls 2_06_6 it showed a dialog box with the title of "assetion failed" and the next information:
expression "offset >= 0"
file: source\database\dwgfiler\dwgstream.cpp
line: 158
if we press ignore, it will stop with another dialog box "out of range".
i am not including the files in this moment, since they are from a customer and i need clearance from them, but maybe this is enough information to find the problem. if i get permission, i will include a zip with the original 2008 file (that work fine) and the 2000/2004 that doesn't.
thanks
edit: this is what the call stack window shows about the error in visual studio:
