Hi Aspose team,
any news here (3 years are past)?
This is to inform you that saving a password protected file is not supported yet. However, you may read the password protected document using the following code sample:
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.FullName); Project project = new Project(dataDir + "PasswordProtectedProject.mpp", "password");
We will let you know as soon as saving the password protected document functionality shall be available. Sorry for inconvenience.
