Hi,
Tested newest Aspose.Cells.dll (8.3.1.0) before including it my project and got issue.
NullReferenceException is thrown when I try to open some files:
- regular OOXML Word and PowerPoint files. CellsException with code ExceptionType.FileFormat must be thrown;
- password-protected OOXML Word and PowerPoint files if valid password is specified. As valid password was specified, and file was decrypted, then CellsException with code ExceptionType.FileFormat must be thrown.
Sample files and project attached.
Thanks,
Alex Shloma
