In the COM add-in, make sure to add the following line of code to the OnConnection subroutine of the add-in instance:

Application.COMAddIns.Item(&quot;MyOfficeAddin.Connect&quot;).Object = Me Change &quot;MyOfficeAddin&quot; to reflect the name of your add-in in the project. Change &quot;Connect&quot; to reflect the name of your designer in the project.

Your code may look like the following code:

Private Sub IDTExtensibility2_OnConnection(ByVal Application As Object, _        ByVal ConnectMode As AddInDesignerObjects.ext_ConnectMode, _         ByVal AddInInst As Object, custom As Variant)

Application.COMAddIns.Item(&quot;MyAddin.Connect&quot;).Object = Me End Sub To instantiate the COM add-in from Microsoft Visual Basic for Applications or Microsoft Visual Basic Scripting Edition code: Set myObj = Application.COMAddIns.Item(&quot;MyOfficeAddin.Connect&quot;).Object Again, make sure &quot;MyOfficeAddin&quot; and &quot;Connect&quot; reflect the names that you created in your COM add-in project. You can then use the myObj variable to reference the objects that you created in the COM add-in.
