password protected dwg file for acad 2007
password protected dwg file for acad 2007
hi everybady,
i have a question about seeting up password for dwg 2007 files. is there some way to setup a password correctly, that the file can be loaded by acad 2007? i'm using dwgdirect 2.40 version.
thanks for help.

see codamfcappdoc:nsavedocument(lpctstr lpszpathname) from odamfcapp sample for sample code.

one more thing:
note that password protected files saved by dwgdirect and autocad 2008 can't be loaded by autocad 2007.
the reason:
autocad 2007 has a serious defect: in password-protected files saved by it the contents of file is not really encrypted. if someone simply ignore information from security section he would be able to load the file without providing the password.
in autocad 2008 they fixed this defect - the contents of password-protected file is encrypted.
as a result autocad 2008 can load password protected files saved by ac2007 and by ac2008. but autocad 2007 is not able to load ac2008 protected files.
dwgdirect reads/saves files as autocad 2008.
