I have some code in A2010 that interfaces with SolidWorks EPDM api using
early binding. Some user don't have EPDM installed so I would like to use
late binder, currently I have to maintain 2 version of the FE. The problem
is EPDM is a Windows File Explore add-on and has no separate user interface
to call using something like CreateObject("Outlook.Application"). How can I
late bind with an add-on application?

A user interface is not required. For example, you can use late binding with
a DAO object:

set db=createobject("DAO.Database")

Late binding will not work if the software is not installed at all. You
cannot create a connection to software that just isn't there. The difference
between early and late binding is speed and versioning. The difference in
code is like this:

Early Binding:
' Declare the object as an early-bound object
Dim objAccess As Access.Application

Set objAccess = CreateObject("Access.Application")

' The Visible property is called
objAccess.Visible = True


Late Binding:
' Declare the object as a late-bound object
Dim objAccess As Object

Set objAccess = CreateObject("Access.Application")

' The Visible property is called
objAccess.Visible = True

With late binding, I can check if the application is not installed and not
run the code. With early binding the FE cannot be loaded if the application
is missing.

Can you post some sample code showing how you start using it?

This is the function I use to login to EPDM

'-------------------
' Opens the Vault and hold open in static var
' Keep ref to vault open for improved speed
'
' Return Reference to the vault
'
Private Function EPDM_GetVault() As EdmVault5

Static m_Vault As IEdmVault12

' Open vault
If m_Vault Is Nothing Then
Set m_Vault = New EdmVault5
' Loginto vault, using current user login
Call m_Vault.LoginAuto("SWVault", "None"), _
GetAccesshWnd())
Else
If Not m_Vault.IsLoggedIn Then
' Loginto vault, using current user login
Call m_Vault.LoginAuto("SWVault", "None"), GetAccesshWnd())
End If
End If

Set EPDM_GetVault = m_Vault ' Return reference to Vault
Exit Function

End Function

I strip out code that looks up the vault name "SWVault"

Call m_Vault.LoginAuto("SWVault", "None"), GetAccesshWnd())

should be

Call m_Vault.LoginAuto("SWVault", "None", GetAccesshWnd())

Well, there's also recoverability when the external component is not
installed.

I really don't think the OP thought the software would somehow
magically work if not installed but programmed through late binding
-- I think all he wanted to do was fail gracefully, since it allows
you to continue running code and tell the user it's not installed.

Basically, you need to find the name of the component that you need
to initialize with CreateObject. You have to poke around the
registry for this. I would start by looking up the name of the file
in the early binding reference, and then search the registry for
that.

With this API New is used instead of CreateObject. I am thinking that the
application is running under Windows explorer. See my code posted earler.
