Not that there's anything wrong with that but for future reference note that the following would also work:
VB Code:
  1. If Not Me.ccTextBox.Enabled OrElse Me.ValidateNonEmptyString(Me.ccTextBox.Text) Then
  2.             Me.ErrorProvider.SetError(Me.ccTextBox, Nothing)
  3.         Else
  4.             Me.ErrorProvider.SetError(Me.ccTextBox, ERR_MSG)
  5.             errCount += 1
  6.         End If
If you weren't going to use an Else block then that might be preferable. As you are using an Else block neither is any better than the other.
