Visual Basic 2005 Express Edition:

I am trying to write out a record to an SQL database table:

Private Sub WriteOutRx()

Me.RxBindingSource.Current("PatientLastName") = PatientLastName <---Error on this line

Me.Validate()

Me.RxTableAdapter.Update(Me.RxDataSet.Rx)

End Sub

Below is the error message that I got:

NullReferenceException was Unhandled

Object variable or With block variable not set.

use the 'new' keyword to create an object instance.

Verify the BindingSource in not empty.
You can do this by testing the BindingSource.Position property (must be greater than -1).
