Seems the sample does not act the same under v1.1 of .NET
as under v1.0.
I was hoping to run it under v1.1. Any ideas?

Hi Kevin,
I noticed that your question has not received a reply. Then I noticed it's
a beta question (not supported).
You might try this other newsgroup: Microsoft.public.dotnet.framework.sdk
I've seen modest volumes of beta questions there and some are receiving
replies.
Good luck with your question.
Thank you, Mike Moore

1. MSDN survey sample problem - column named 'Answer' already belongs to this DataT
When I run the Survey sample app I get the error "Error:
A column named 'Answer' already belongs to this
DataTable". An exception is thrown from Sub
AdjustQuestionPrimaryKey() in SurveyDataSet.vb. Any ideas?
