VB- ADO Returns a recordcount of -1

This should be a really easy one. I have the following code:

SQLConnect = "Provider=SQLOLEDB;Data Source=CLUSTERNAME\CLUSTERINSTANCE;Initial Catalog=MyTable;Integrated Security=SSPI;"
Conn1.ConnectionString = SQLConnect
Cmd1.ActiveConnection = Conn1
Cmd1.CommandText = "Select MyColumn from MyTable where Need2Publish = 1"
Set Rs1 = Cmd1.Execute
i = 1
x = 1
intCount = Rs1.RecordCount
MsgBox intCount

This always produces a RecordCount of -1, even though there are 2 records? I know for a fact there are two records because if I do this:

intCount = 2
If intCount > 0 Then
    ReDim strVarName(intCount)
    Do Until Rs1.EOF
        strVarName(i) = Rs1.Fields(0).Value
        MsgBox (strVarName(i))
        i = i + 1
End If

It returns my 2 values in the message box...

Does anyone have an explanation to this?

This is becuase you are not specifying the type of recordset that you want to open. ADO by default will open a Forward only recordset and it will always return -1. Open a dynamic or keyset recordset and it will give you a recordcount. Another way of getting the total no of records is by opening another recordset:
strSQL="Select Count(*) from tblTableName"

Do not use a Command object for a simple query like this. Conisder this:

SQLConnect = "Provider=SQLOLEDB;Data Source=CLUSTERNAME\CLUSTERINSTANCE;Initial Catalog=MyTable;Integrated Security=SSPI;"
Conn1.ConnectionString = SQLConnect
set rs1 = new adodb.recordset
rs1.cursorlocation = aduseclient
rs1.open "Select MyColumn from MyTable where Need2Publish = 1", conn1
msgbox Rs1.RecordCount

Why does aduseclient work and aduseserver not? Why is this the only way to get at the recordcount property?
