user control problem

New to VB.NET

I have an application with 2 usercontrols on a Form called Main

Login and PhoneLog

When the app runs the phonelog is not visable and the login is.

I am able to login and hide the login control but the phonelog control will not change to visable.

I think this is a lack of the proper reference somewhere but I'm not sure.

I get an error on the Debug for this line of code inside the Login control.

****The Following code is from the Usercontrol Login:*******

Public Function AuthOK()
        Me.Hide()
        Dim frmMain As Main
        frmMain.PhoneLog1.Visible = True '**** This code breaks

    End Function

*****************************************
This is the Error:
An unhandled exception of type 'System.NullReferenceException' occurred in ManagementSystem.exe

Additional information: Object reference not set to an instance of an object.
*****************************************

Please Help

hehehe. When one is in rush of an answer, this forum really takes time, unlike the public ms newsgroup. If they really lack people, I can do it, part time, :p

A NullReferenceException occurs when you try to access the properties or methods of a variable that has not been initialized.
Dim frmMain as Main

' It's not enough to declare the variable.
' It also needs to be initialized
frmMain = new Main

' now frmMain is safe to use

you forgot to instantiate the second form:

Public Function AuthOK()
Me.Hide()
Dim frmMain As <b>New Main()</b>
frmMain.PhoneLog1.Visible = True '**** This code breaks

Darn these moderated forums :) This doesn't happen when the post shows up immediately.

Dim frmMain As new Main
