Default Chapter 12 - LogIn

Hi: After signing in using a user LoginName and Password, I receive an exception error in the TimeSheet.vb class. It occurs in the LoadTimeSheet Sub, on the "intTotal +=objTimeSheetDS. . . " statement(Calculation of total hours for Monday ) and is an InvalidCastException stating that "Operator '+' is not defined for type 'Integer' and type 'DBNull'. I have rechecked my Stored Procedures and related routines, but could not come up with any errors.

Any help I receive resulting in the solution of this problem will be greatly appreciated.

My email is megarxsales@hotmail.com

Thanx, Braaxx

Richard Krasner

Richard,

Please review this post, http://p2p.wrox.com/topic.asp?TOPIC_...chTerms=dbnull, and also recheck your steps. A timesheet should be prepopulated with zeroes if it does not previously exist.
