oderror thrown when writing database
oderror thrown when writing database
when writing a dwg file via oddbdatabase::writefile, where the database has a populated layer table, an exception with the following description is getting thrown:
"w object: (2)"
what does this mean? my code previously did not set up a layer table or assign oddbentities a layer, and the call to oddbdatabase::writefile worked without problems.
neglected to mention i'm using dwgdirect 2.20, and am calling writefile with oddb::vac18.
most probably this the situation described in faq:
writefile() is throwing an ewasopenforwrite exception when i try to save out a dwg/dxf drawing.
or at
btw, does err.description() return the strange string "w object: (2)"?

yes, am calling description() on the error thrown.
in case of ewasopenforwrite exception the description should be:
"was open for write object (3b)"
3b - is the handle of object which was modified but was not closed before file saving.
note that since 2.0 odchar is wchar_t and casting it to char* may cause problems because odchar* is a pointer to unicode string.

i also converted my code to use unicode strings when i updated to 2.2, so i don't think that's an issue.
