Get  Run-time Error '424': Object Required when trying to implement an ActiveX Merge Control in an MS Access Project

Posted on 2008-10-11
Last Modified: 2013-12-05
I have a MS Access project that connects to an MSDE database on the same laptop.  I also have the same MSDE located on a server.  Merge replication is set up between the two and is currently controlled using Window Synchronization Manager.  Works good.  I want to place merge control in the Access project so that the endusers only need to use the Access project to initiate replication.  I'm using the ActiveX Merge Control to try to do this.  I found an article in SQL Server Magazine that uses the attached code.  Listing 1 is a classmodule that allows access to the merge control's Status Event.  Listing 2 is the merge replication function.   When I run the Replication_Merge function in the VBE Immeadiate Pane I get the Run-Time error 424: Object Required.  The 4th line of listing 2 "Set Merge_Control = New_Merge.SQlM" is highlighted yellow when I debug.  The contents of the article are also attached.

LISTING 1: Creating a Class Module That Uses the Status Event

Public WithEvents SQlM As SQLMerge

Private Sub Class_Initialize()

   Set SQlM = New SQLMerge

End Sub

Private Sub Class_Terminate()

    Set SQlM = Nothing

End Sub

Private Function SQLM_Status(ByVal Message As String, ByVal Percent As Long) As SQLMERGXLib.STATUS_RETURN_CODE

    Debug.Print Message & " " & Percent & "% Done"

End Function

LISTING 2: The Replication_Merge Function

Public New_Merge As New clsMerge

Public Function Replication_Merge()

Dim Merge_Control As SQLMerge

Set Merge_Control = New_Merge.SQlM


With Merge_Control

	'Set the publisher properties

	.Publisher = "Your Server Name"

	.PublisherSecurityMode = DB_AUTHENTICATION

	.PublisherLogin = "sa"

	.PublisherPassword = ""

	.PublisherDatabase = "Pubs"

	.Publication = "pubs_to_MSDE"


	.PublisherNetwork = TCPIP_SOCKETS

	.PublisherAddress = ""


	'Set the distributor properties

	.Distributor = "Distributer Server Name"

	.DistributorSecurityMode = NT_AUTHENTICATION


	'Set your local subscriber properties

	.Subscriber = "The Local Machine Name/Server Name"

	.SubscriberSecurityMode = DB_AUTHENTICATION

	.SubscriberDatasourceType = SQL_SERVER

	.SubscriberLogin = "sa"

	.SubscriberPassword = ""

	.SubscriberDatabase = "pubs_local"

	.SubscriptionType = ANONYMOUS





End With



End Function

If you debug the code, do you get the same error?
I'm thinking that this could be a references issue.

I pasted your code into an adp, i.e. first part as new class module named clsMerge, and second part as new module; in VBA, added reference to Microsoft SQL Merge Control 8, then ran Replication_Merge in immediate panel, and it worked. Of course it returned error message about not finding the subscription ("The process could not connect to Subscriber 'The Local Machine Name/Server Name'. 0% Done") , but not "object required".

Thanks - I had the function in a module with a few other functions used throughout the project.  I put it in its own module and it works.
