How do I create very long field/column widths greater than 8000 characters in my datapage?

If you have Web Scraper 5.5 installed with SQL Server 2005, you can change your Datapage field length to -1 in the field properties->Tags (Manual) tab.
Then you need run the following SQL Server Query to update your database settings so that Web Scraper knows how to interpret fields with length of -1:

use ProvidusDB
INSERT INTO [ProvidusDB].[dbo].[settings]
           ([name]
           ,[val]
           ,[datatype]
           ,[parent])
     VALUES
           ('IsSql2k5'
           ,'true'
           ,'bool'
           ,null)
