Hello,

I get an exception when trying to load a file from stream. This is the code that I use to load the presentation:

Code: Select all
using (FileStream fs = File.Open(fileName, FileMode.Open))
{
    presentationFromDisk.LoadFromStream(fs, FileFormat.Auto);
}


The exception with the stack trace is the following:

System.NullReferenceException Object reference not set to an instance of an object.

This happens with just one presentation. It is larger than the maximum allowed attachment size, so if you need the file, I can send it via e-mail.

If you could help make sense of the stack trace or solving the issue it would be very appreciated.

All the best,

Dusan.
