mmm... where are you working ?
into the codebehind(VB) of a control (.ascx)?
into Java-Script for the final display?
Normaly(without DSLocalizator) in VB you can get tab via the TabController class:
ie:
Dim MyController As DotNetNuke.Entities.Tabs.TabController
Dim MyTab As DotNetNuke.Entities.TabInfo
Dim MyTabTitle As String
MyTab = MyController.GetTabs(putTabIDHere)
MyTabTitle = MyTab.LocalizedTabName
Please tell me what you want to do. then i will help you more ^^
