Example

The following example creates a reference to a specified type library:

Function ReferenceFromFile(strFileName As String) As Boolean
    Dim ref As Reference

    On Error GoTo Error_ReferenceFromFile
    ' Create new reference.
    Set ref = References.AddFromFile(strFileName)
    ReferenceFromFile = True

Exit_ReferenceFromFile:
    Exit Function

Error_ReferenceFromFile:
    MsgBox Err & ": " & Err.Description
    ReferenceFromFile = False
    Resume Exit_ReferenceFromFile
End Function

You could call this function by using a procedure such as the following, which creates a reference to the calendar control:

Sub CreateCalendarReference()
    If ReferenceFromFile("C:\Windows\System\Mscal.ocx") = True Then
        MsgBox "Reference to calendar control created successfully."
    Else
        MsgBox "Reference to calendar control not created successfully."
    End If
End Sub
