Public Enumeration AddInSegmentType

Member nameDescription

Specifies an add-in segment.


Specifies an add-in-side adapter segment.


Specifies an add-in view segment.


Specifies a contract segment.


Specifies a host-side adapter segment.


Specifies the host view of the add-in segment.

In this context, the type of a pipeline segment identifies the category of pipeline segment: add-in, add-in-side adapter, add-in view, contract, host-side adapter, or the host view of the add-in. If a pipeline segment's class has a QualificationDataAttribute attribute, you can obtain the data specified in the attribute with the QualificationData property of an AddInToken object.

The following example uses the AddInSegmentType enumeration to evaluate an add-in's qualification data.

' Use qualification data to control
' how an add-in should be activated.

If selectedToken.QualificationData(AddInSegmentType.AddIn)("Isolation").Equals("NewProcess") Then
    ' Create an external process.
    Dim external As AddInProcess = New AddInProcess

    ' Activate an add-in in an automatically generated
    ' application domain with a full trust security level.
    Dim CalcAddin5 As Calculator = _
        selectedToken.Activate(Of Calculator)(external, _
    Console.WriteLine("Add-in activated per qualification data.")
    Console.WriteLine("This add-in is not designated to be activated in a new process.")
End If
