Hi ,

Thanks a lot for your reply. Here is my new scenario.


We have a ".one" format document which is of size 133MB (confidentil document). Hence i can not upload that document.. sorry.

We found that, the original ".one" format document can be converted to .pdf. But when that document is edited and tried to convert, it thows error "System.IO.InvalidDataException: The Md5 hash is not correct for object declaration struct."


As you suggested, I have used the latest dll. Here in my case, Aspose.Notes.dll version (Aspose.Note for .NET 2.5.0). Now the above problem got resolved.

But while executing the below line, its giving us error "System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown"

Below is my code:

System.IO.MemoryStream stream = new System.IO.MemoryStream();
Aspose.Note.Document doc = new Aspose.Note.Document(new MemoryStream(docContentBytes));

doc.Save(stream, Aspose.Note.SaveFormat.Pdf); -- Here, the error occurs.

Please help.
