Accessing publication properties from Visual Basic (VB6)

Hi all,

I have an existing application that checks a few things before it
launches another application. One thing that the application needs to
check is the subscription properties of both the local database and the
remote (LAN) server.

I've stumbled upon some properties but I am trying to fit in the last
ones and I can't seem to find the right code to accomplish this... Can
anyone shine a little light on this please ?

The following code queries the SQL Server (remote) to get (some of) the
properties of the replicated database. What I would like to fit in
after the 'state' are the properties that you can retrieve with the
 EnumAllSubscriptions
 function. However, I can't seem to find the right
object (sample code) to retrieve those (or I'm just overlooking the
obvious)...

Here is (part of) the code I'm using to query the publication on the
remote server :

Dim oMergePublication As SQLDMO.MergePublication2
Dim oSubscription As SQLDMO.MergeSubscription2

Me.lstPublications.Clear
For Each  oReplicationDatabase
 In
objSQLSERVER.Replication. ReplicationDatabases

If  oReplicationDatabase
.Name = Me. txtSQLServerDatabase
.Text
Then
For Each oMergePublication In
 oReplicationDatabase
.MergePublications
bFoundReplicated = True
Me.lstPublications.AddItem "Database replicated as
'" & oMergePublication.Name & "'"
For Each oSubscription In
oMergePublication.MergeSubscriptions
Me.lstPublications.AddItem "     - subscriber
:" & oSubscription.Subscriber
Me.lstPublications.AddItem "          - local
DB :" & oSubscription.SubscriptionDB
Me.lstPublications.AddItem "               -
state :" &  GetReplStatus(oSubsc
ription.Status)
Next
Next
'For Each osubscriber In  oReplicationDatabase
.
'Next
End If
Next
Set  oReplicationDatabase
 = Nothing
Set oMergePublication = Nothing

After this, I also want to check the local DB (=pulled subscription)
and show some of the properties (from  EnumAllSubscriptions
). For
example to warn the user about the need to synchronise (last_updated
value)...

Any help appreciated,

Many thanks

I'm not sure what you're asking - do you mean that you know that
 EnumAllScubscription
s will return the information you need, but you
don't know how to manipulate a SQL-DMO QueryResults object? If so, then
you need to iterate over it, and use the GetColumn% methods to return
the data in the format you want - in this case, GetColumnString is
probably the best one to use.

This is a simple VBScript example of using a QueryResults object:

Option Explicit

Dim oSrv, res, c, r

Set oSrv = WScript.CreateObject("SQLDMO.SqlServer2")
oSrv.LoginSecure = True
oSrv.Name = "MyServer"
oSrv.Connect

Set res = oSrv.ExecuteWithResults("select * from sysobjects")

For r = 1 To res.Rows
For c = 1 To res.Columns
If res.ColumnName(c) = "name" Then
WScript.Echo res.GetColumnString(r, c)
End If
Next
Next


If this isn't helpful, you might get a better answer in
microsoft.public.sqlserver.replication.

Sort of Simon,

I'm having difficulty to get the returnset from  EnumAllSubscriptions
 in
a workable object. It just returns nothing or won't compile.
In the code I've added, I managed to get the right call for the
 EnumAllSubscriptions
 but I'm not sure on the syntax it requires. Like :

Dim oSubscription as SQLDMO.Subscriber2
Dim oSubscriptionData as SQLDMO.<??>
For each oSubscriptiondata in
oSubscription. EnumAllSubscribers(S
 QLDMOSubscription_Al
l)

OR do I need to make something like
Dim Result
Dim oSubscription as SQLDMO.Subscriber2
Result = oSubscription. EnumAllSubscribers(S
 QLDMOSubscription_Al
l)
and then walk that Result for the correct data

Thanks anyway. I'll give this a try in the .repication group.
