This is the code: Dim dr() As DataRow = DataSet.Tables(TableName).Select(EVENTNAME = ‘ & name

  • 0

This is the code:

Dim dr() As DataRow = DataSet.Tables("TableName").Select("EVENTNAME = '" & name & "'")

I get an “Object reference not set to an instance of an object.” Error when this line is executed. It is looping through a list of selected items in a listbox. I think it has to do with how I have the datarow declared because I can look at the name and I see it ok and I also do a null check on the name before I use it.

Visual Studio 2008, VB.NET. Any ideas?

Yep it was a wrong table name. I guess after looking at the code for 8 hours that minor detail I just wasn’t thinking to check. Thanks!

    You probably have the wrong "TableName".
