Default Class Object reference error.

I'm trying to write debugging information to the Trace stack as my code executes. However, I recieve "Object reference not set to an instance of an object." with the code
Code:
Line 55:         '----------------------------------------------------
Line 56:         Dim TraceWrite As UserControl
Line 57:         TraceWrite.Trace.Write("Begin GetUserID")
Line 58: 
Line 59:         If HttpContext.Current.Session("UserID") Is Nothing Then
 

Source File: C:\Inetpub\wwwroot\Modules\Modules\DB\DataLayer.vb    Line: 57 

Stack Trace: 


[NullReferenceException: Object reference not set to an instance of an object.]
   Modules.DataLayer.GetUserID() in C:\Inetpub\wwwroot\Modules\Modules\DB\DataLayer.vb:57
   Modules.LinkBar.Page_Load(Object sender, EventArgs e) in C:\Inetpub\wwwroot\Modules\Controls\LinkBar.ascx.vb:30
   System.Web.UI.Control.OnLoad(EventArgs e)
   System.Web.UI.Control.LoadRecursive()
   System.Web.UI.Control.LoadRecursive()
   System.Web.UI.Control.LoadRecursive()
   System.Web.UI.Control.LoadRecursive()
   System.Web.UI.Control.LoadRecursive()
   System.Web.UI.Control.LoadRecursive()
   System.Web.UI.Page.ProcessRequestMain()
Any help is appreciated.

Hi Michael,

If u want to create NEW User COntrol everytime, you shud use "new" while
declaring user control as follows:

        Dim TraceWrite As New UserControl

Let me know if it works..

Regards,
Muskaan. :)
