If the tab (page) name is unique across the portal, the following should work:

Dim tCtlr As New DotNetNuke.Entities.Tabs.TabController
Dim tInfo As DotNetNuke.Entities.Tabs.TabInfo = tCtlr.GetTabByName(tabName, PortalId)
Dim tID As Integer = -1
If Not tInfo Is Nothing Then
     tID = tInfo.TabID
End If

If the tab name is not unique - that is, it is used on multiple child pages, the method GetTabByName can take a third parameter - that of the ParentTabID.

William,

I saw your reply above.When I try it, all works accept the fact that "tabName" cannot be directly referenced like you show in the 2nd line of the code example.Error I get is that "tabName" is not declared, so I tried to reference it as tInfo.tabName.But then of course I get a warning that tInfo is being used without first being given a value, which allows for this to compile, but at runtime the object is null, failing the code. Any idea what I am doing wrong here?

Thanks in advance.
