I did search the formums and found no info, also searched the faq, and found the below info which is good in that at least the problem has been identified and analyzed and I get the sense there is a solution, but I need more help and I think a forum answer would also help others.
****** FROM FAQ **********************
Isolated storage ErrorWhen calling FlexCel from COM or Native Code:
You might also get the following Exception:System.IO.IsolatedStorage.IsolatedStorageException: Unable to determine the identity of domain.
When calling FlexCel from a COM component or a native one. In this case, the problem is most likely that you are missing the "evidence" in the appdomain, as it is not created automatically when calling .NET from COM.
If that is the issue, you can fix it either by creating a new AppDomain with evidence and running the FlexCel code in it, or you might try to patch the current AppDomain to add an evidence. [Adrian Gallero (May 30, 2011)]
***************************************************************************
I am pretty certain I need to "add an evidence", I'm using .NET 3.5, C#, but I have NO IDEA how to do this. I found various generic examples from google searches, but nothing I've tried has fixed this problem. I have a gut feeling the answer is burried in the following link:
But I'm not smart enough to figure it out, and the code isn't C#.
Since this question has been addressed in the FAQ, I'm REALLY hoping you guys have some sample code I can copy to address this problem.
For what its worth, when getting the error, it is running in a C# script in an SSIS package, under a domain account with local admin rights. I just need sample C# code that shows how to do the evidence stuff. The error only occurs when generating >7MB files as described in the FAQ.
Thanks so much for any help! We just bought flexcel a week or two ago, loved the tool until I hit this wall.
