how to know the password in a dwg file?
how to know if a dwg file is the password protected file by using the dwgdirect library? can i get out of the password within a passworded dwg file by using the library? if does, how to do it? we are planning to build a friendly secure environment within a company, and need this function to enable the source drawings to be view or referenced but not be editted.
if you call readfile() or recoverfile() without passing password to it and oddbhostappservices::getpassword() is called from readfile() than the file is password-protected.
if a file is password-protected to open it you must know the password and pass it to readfile() or return it from getpassword() callback.
