I never bother checking for nulls; if there's a field that could potentially be null, I just string it as a matter of practice: baddress2.text=mySingleMemberDtr("b_address2").ToString() -----Original Message----- From: thelist-bounces at lists.evolt.org On Behalf Of David Travis Hi Casey, You should have something like this: Dim adrs2 as String If TypeOf myRow["adrs2"] Is DbNull Then adrs2 = String.Empty Else adrs2 = myRow["adrs2"].ToString() End If I am writing this code without testing it, and it was a while since I worked with VB.NET, so I am not sure this is 100% working, but that's the main idea. Good Luck! David Travis. -----Original Message----- From: thelist-bounces at lists.evolt.org On Behalf Of Casey Crookston asp.net in vb... I'm populating a form from a database row. There's a column in the db for address and address2 incase the user needs a second line for their address. In the db address2 is allowed a null value, but when trying to populate the form I get this error: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Cast from type 'DBNull' to type 'String' is not valid. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidCastException: Cast from type 'DBNull' to type 'String' is not valid. Source Error: Line 95: baddress2.text=mySingleMemberDtr("b_address2") ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Makes sense, I guess. It won't let a null value be passed into a text string. What can I do to allow a null value to be entered. I REALLY don't want to have to force the user to enter something like "n/a" into the field if it is empty. Or, what's the best way to have a value look empty when it's not? Thanks!
