Summary

This article explains how to correctly reference a COM add-in that binds to Outlook.

More information

Microsoft provides programming examples for illustration only, without warranty either expressed or implied, including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose. This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures. Microsoft support professionals can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific needs.
If you have limited programming experience, you may want to contact a Microsoft Certified Partner or Microsoft Advisory Services. For more information, visit these Microsoft Web sites:

Microsoft Certified Partners - https://partner.microsoft.com/global/30000104

Microsoft Advisory Services - http://support.microsoft.com/gp/advisoryservice

For more information about the support options that are available and about how to contact Microsoft, visit the following Microsoft Web site:http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS 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("MyOfficeAddin.Connect").Object = Me
				
Change "MyOfficeAddin" to reflect the name of your add-in in the project. Change "Connect" 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("MyAddin.Connect").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("MyOfficeAddin.Connect").Object
				
Again, make sure "MyOfficeAddin" and "Connect" 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.
