Hi Mindy,

In looking at your code, you don't seem to be initializing "dr". Change your code to the following:

Dim dtFoxProNull As DateTime = DateTime.Parse("12/10/1899")
For Each dr As DataRow In DSfatrans.Tables("fatrans").Rows
    If (DateTime.Parse(dr("tr_chkdate").ToString()) = dtFoxProNull) Then
        dr("tr_chkdate") = DBNull.Value
    End If
Next
DSfatrans.AcceptChanges()

>tr_chkdate is a column in my grid that will often be blank. Currently it's displaying a default date of 12/10/1899 rather than a null date.
