Hello,

I have a problem with saving a visio files in VSDX format. I got ArgumentNullException: key cannot be null.

The code I’m using looks like this:
Diagram visio = new Diagram(“test.vsd”);
visio.Save(“test.vsdx”, SaveFileFormat.VSDX);

I’ve attached test.zip (48.2 KB) which cause this problem.

Thanks,

I used your hotfix but I still get the exception. Try this file:test.zip (48.1 KB)
I got exception:
System.InvalidOperationException: ‘This is not a structured storage file.’

Sorry, You are right. Hotfix works now. My mistake was that I had enabled All exceptions in visual studio so there was exception thrown for this file but when I continue program execution then everything is ok.
So basically problem solved!

Thanks
