Need help to programatically drop a column from Listview

I am using VB.Net 2005

I want to drop a column from a listview. My code is throwing an error and I don't know why. Please help me fix it.

I put a message beside the offending line in the code. The error reads:

Null Reference Exception was unhandled.
Object reference not set to an instance of an object.

Thanks

            Dim instance As ListView.ColumnHeaderCollection
            If column.Text = "Block" Then
                instance.Remove(column) ' error thown here
            End If
        Next
