Hi I am integrating our existing web application so it can be implemented as modules in a DNN website.  Part of this means having a double login which I have figured out how to do.  I just create the DNN Users on the fly after the username/password has been validated by our application.  This creation only happens the first time the person signs in.  After that whenever they log in it checks the username pass on our member ablication and then progromatically logs you into DotNetNuke. 

Now our application has permissions just like DNN so i duplicated the roles in dotnetnuke.  After i create the DNN user for the first time I add the roles programattically using the Subroutine

Sub AddUserRole(PortalID, UserID, RoleID, ExpirationDate)

The only problem is when i do it it give me this error: Object reference not set to an instance of an object.  However when I check the DNN UserRoles table the roles get added correctly so I'm not sure where the error would possibly  be coming from.

The function code is below.  Please help.  Thank you.

Public Sub AddUserRole(ByVal PortalID As Integer, ByVal UserId As Integer, ByVal RoleId As Integer, ByVal ExpiryDate As Date)

Dim originalAppName As String = ""

Dim objUserController As New UserController
Dim objUser As UserInfo = objUserController.GetUser(PortalID, UserId)
Dim objUserRole As UserRoleInfo = GetUserRole(PortalID, UserId, RoleId)
           
If objUserRole Is Nothing Then
                originalAppName = Common.Globals.GetApplicationName
                Common.Globals.SetApplicationName(PortalID)
                DataProvider.Instance().AddUserRole(PortalID, UserId, RoleId, ExpiryDate)
                objUserRole = GetUserRole(PortalID, UserId, RoleId)
                Try
                    AspNetSecurity.Roles.AddUserToRole(objUser.Membership.Username, objUserRole.RoleName)
                Catch ex As Exception
                    'Reset the Application Name
                    Common.Globals.SetApplicationName(originalAppName)                End Try
            Else
                DataProvider.Instance().UpdateUserRole(objUserRole.UserRoleID, ExpiryDate)
                
 End If

End Sub

False alarm.  I use a session string to store the current roles from my member application.  It was uknown to me that when you use Redim ArrayVar(X) that X is not the LENGTH of the array but the Upperbound (Length -1) of the array which to me is really stupid.  After doing some reading i learned that using redim in the first place is pretty amateur so i changed my ways.  And Viola...Perfection.
