I took the dnld from the article and tried in vain to compile/deploy/run the Solution.

I'm failing with the following:

L:\ZipStuff\XLSExport\XLSExport\bin\Debug\iCExport.sql(39-39): Deploy error SQL01268: .Net SqlClient Data Provider: Msg 6503, Level 16, State 12, Line 1 Assembly 'npoi.hssf, version=0.0.0.0, culture=neutral, publickeytoken=null.' was not found in the SQL catalog.

Any ideas on how to correct? and Yes I did the SQL configuration to enable CLR and Alter for Trust on the database.

Thanks, Sid
