Public Function CheckReg(ByVal ModuleId As Integer, ByVal UserId As Integer) As String

    Return DataProvider.Instance().CheckReg(ModuleId, UserId)
End Function

Example Page Codebehind
Dim objExample As New ExampleController
Dim MyString As String

MyString = objExample.GetValue(ModuleId, UserId)
lblMyString.Text = MyString.ToString

My output
Object reference not set to an instance of an object.

I have a feeling I need the CBO but I am uncertain how to use it as this is not a collection of information its a single value returned from a stored procedure. 

Suggestions??
