      • This might be the wrong forum for this question, but I wasnt 100% which one it should be in. Basically, I'm writing a VB.NET database application which hooks up to an SQL 2005 server. I'm having a problem with nulls - when I try to assign a value of a field which is null to field on a VB.NET form, I get the error "Conversion from type 'DBNull' to type 'String' is not valid."
