IsNullOrEmpty is 'shared' so you should use it that way:
If String.IsNullOrEmpty(strTest) Then
You can actually just compare to an empty string:
If strTest = "" Then
MessageBox.Show("NULL OR EMPTY")
End If
String.IsNullOrEmpty is a shared (or static, in C#) method.
Dim strTest As String
If (String.IsNullOrEmpty(strTest)) Then
MessageBox.Show("NULL OR EMPTY")
End if
