If txtLocation.Text.ToString <> "" And txtUnitTested.Text.ToString <> "" Then
Dim filewriter As New System.IO.StreamWriter(
"C:\Users\OER\Documents\Visual Studio 2010\Projects\frmTest1_0.txt")
Dim curItem = lstCustomer.SelectedItem
Dim now As DateTime = DateTime.Now
With filewriter
.WriteLine(vbCrLf + (now.ToString("F"))) ' Write the DateTime to the file
End With
For Each objDataRowView As DataRowView In lstCustomer.SelectedItems
Dim item As String
For Each item As DataRowView In Me.lstCustomer.Items.Item("customer")
item = String.Parse(lstCustomer.SelectedValue)
WriteLine(curItem(item))
Next item
Next ' THIS IS THE FOR LOOP I AM HAVING ISSUES WITH!!!!!!!
With filewriter
.WriteLine(vbCrLf + txtLocation.Text + vbCrLf + txtUnitTested.Text)
