currentproject.connection vs connection string ms access / sql server

I have a function that was written in DAO against ms access mdb backend that i have converted to sql server backend with linked tables.

I have linked tables.  The function uses transactions which i have already determined to not work with DAO and SQL Server based on experience and research.  So i went about converting to ado.

the transactjon setup was
  Dim NewCheck As New adodb.Recordset
 Set TransTemp = DBEngine.Workspaces(0)
    Set CurDb = TransTemp.Databases(0)
   TransTemp.BeginTrans

i am opening the recordset like this:

      NewCheck.Open sqlstmt, CurrentProject.Connection, adUseClient, adLockBatchOptimistic

 NewCheck.AddNew
       NewCheck![Trans Type] = "Check"
       NewCheck![Account Number] = Account
       NewCheck![Check Number] = NextCheckNum
       NewCheck![Check Date] = Me.Check_Date
       NewCheck![Payee] = ChecksToPay![Supplier Name]
       NewCheck![Supplier Number] = ChecksToPay![Supplier Number]
       NewCheck![Payment Amount] = PmtAmt
       NewCheck![Deposit Amount] = 0
       NewCheck![CurrencyCode] = CurCode
       NewCheck![ExchangeRate] = ExChgRate
       NewCheck![Bill Payment] = True
       NewCheck![Posted] = True
       NewCheck![Memo] = "some memo" ' for SQL Contraint
       NewCheck![Posting GL ID] = "0" ' for SQL Contraint
       NewCheck![Voucher] = "some voucher" ' for SQL Contraint.  this is written later in function


...

 NewCheck.Update
       NewCheck.MoveLast ', NewCheck.LastModified


  TransTemp.CommitTrans


It runs without any error, but does not actually write a new record at all.

Do i need a connection string or will currentproject.connection suffice?  Is the DBEngine.Workspaces(0) workspace even the same workspace as my ado connection??

I start with
Dim cnn As ADODB.Connection

Then
Set cnn = CurrentProject.Connection

and finally

NewCheck.Open sqlstmt, CurrentProject.Connection, adUseClient, adLockBatchOptimistic

Have you explicitly Dim'd the connection as ado as you have done with the Recordset?

This looks like you create the cnn object, but then don't use it when opening the recordset.  

NewCheck.Open sqlstmt, cnn, adUseClient, adLockBatchOptimistic.

So i tried it anyway, and then that make another statement break earlier in the code like so:

   ChecksToPay.Open sqlstmt, CurrentProject.Connection

"Run-TIme error '3251', current provider does not support the necessary interface for Index functionality."

PS:  the ChecksToPay is dim'd this way:
  Dim ChecksToPay As New ADODB.Recordset

in this function some of the recordsets opened are in SQL Server, and others are in a local tmp .mdb file.  So the currentproject.connection points to the frontend file that is open.  So how to i open directly without odbc, the sql table and the tmp table?

There were still some DAO recordsets nested in the transaction.  I removed those and then it worked.
