Determining current user

I am trying to modify the Dot Net Nuke Menu. I have added a conditional to the ist building section of the menu. The goal is to make sure that even if a user is an Admin User, they can only see the Admin tabs if they are user_ID 1 or 2. The problem is that I need to load objUserInfo.UserID with information about the current user. How can I extract the username of the current user as a string? Is this a secure thing to do? I would appriciate hearing better ideas if anyone has one.

Dim objUsers As New Entities.Users.UserController
Dim objUserInfo As Entities.Users.UserInfo

objUserInfo = objUsers.GetUserByUsername(MyPortalSettings.PortalId, <Username As String> )

<...some more code ....>

' Build list of tabs to be shown to user
    For i = 0 To MyPortalSettings.DesktopTabs.Count - 1

      Dim tab As TabInfo = CType(MyPortalSettings.DesktopTabs(i), TabInfo)
      If tab.IsVisible = True And tab.IsDeleted = False Then
                If DotNetNuke.Security.PortalSecurity.IsInRoles(tab.AuthorizedRoles) = True Then
                    If (tab.IsAdminTab = True And (objUserInfo.UserID = 1 Or objUserInfo.UserID = 2)) Or tab.IsAdminTab = False Then
                        authorizedTabs.Add(tab)
                        addedTabs += 1
                    End If
                End If
            End If

        Next i

Re: Determining current user

The UserController can return the current userinfo object.

DotNetNuke.Entities.Users.UserController.GetCurrentUserInfo()

Re: Determining current user

I'm trying to convert an existing asp1.1/dnn2.0 to asp2.0/dnn4.x... it's some code that when logged in a user can become another user (ie home office associate can log in as a customer and see the site the way the customer would see it).

I'm lost. Here's my error

System.Data.SqlClient.SqlException: Conversion failed when converting the varchar value 'Lynne' to data type int. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlDataReader.HasMoreRows() at System.Data.SqlClient.SqlDataReader.ReadInternal(Boolean setTimeout) at System.Data.SqlClient.SqlDataReader.Read() at System.Data.SqlClient.SqlCommand.CompleteExecuteScalar(SqlDataReader ds, Boolean returnSqlValue) at System.Data.SqlClient.SqlCommand.ExecuteScalar() at DotNetNuke.BecomeaUser.IDCheck() at DotNetNuke.BecomeaUser.Page_Load(Object sender, EventArgs e)

I tried implementing you GetCurrentUserInfo()

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load' Obtain PortalSettings from Current Context

Try

DotNetNuke.Entities.Users.UserController.GetCurrentUserInfo()

'Dim _portalSettings As ProviderSettings = CType(Context.Items("PortalSettings"), ProviderSettings)

IDCheck()

' Log User Off from Cookie Authentication System

Dim vUserId As String

' Dim vPass As String

If (Request.Params("Agentid") <> "") Then

vUserId = Request.Params(

Session(

Response.Cookies(

"Agentid")"pRet") = vAgentid"Sub").Value = "555555555"

Response.Cookies(

"Sub").Path = "/"

Else

vUserId = Session(

Session(

"pRet").ToString"pRet") = ""

End If

Dim objSecurity As New Security.PortalSecurityDim blnLogin As Boolean = True

If blnLogin Then

' Attempt to Validate User Credentials

Dim userId As String = vUserId 'objSecurity.UserLogin(vUserId, vPass, 0, 0, 0, 0)

If userId >= 0 Then

formsAuthentication.SignOut()

' expire cookies

Response.Cookies(

"portalid").Value = Nothing

Response.Cookies(

"portalid").Path = "/"

Response.Cookies(

"portalid").Expires = DateTime.Now.AddYears(-30)"portalroles").Value = Nothing

Response.Cookies(

"portalroles").Path = "/"

Response.Cookies(

"portalroles").Expires = DateTime.Now.AddYears(-30)"Sub").Value = Nothing

Response.Cookies(

"Sub").Path = "/"

Response.Cookies(

formsAuthentication.SetAuthCookie(Convert.ToString(userId),

Response.Redirect(

"Sub").Expires = DateTime.Now.AddYears(-30)False)"~/" & "tabid/36/Default.aspx")Else

Response.Write(

"This User is not yet created to be a Web User.2")End If

End If

Response.Write(ex.ToString)

Catch ex As ExceptionEnd Try

End Sub

I'm not having much luck searching so I'm asking in this thread. PLEASE... even a search suggestion would help.

~~You don't need to do either one of these things.~~

IF YOU ARE BUILDING A MODULE, your module should be extended from DotNetNuke.Entities.Modules.PortalModuleBase. In this case, current UserId is explicitly available to you and you can refer to it just like that If UserId = 1 Then... You don't need to do any queries, you don;t need to populate anything.

Another point, if you want to test current user if he/she is a SuperUser or and Admin, you can just say
If UserInfo.IsSuperUser OrElse UserInfo.IsInRole("Administrator") Then...

Re: Determining current user

That would assume he was building a MODULE

- but since he says he is modifying the DNN MENU I kinda assumed he is working on a SKIN - in which case you would not be extending PortalModuleBase.
