Synchronize Method (RDS)

  • Article

Synchronize the given recordset with the database specified by the connection string for use in ADO 2.5 and later.

Syntax

object.Synchronize(ConnectionString As String, HandlerString As String, lSynchronizeOptions As Long, ppRecordset As Object, pStatusArray, [lcid As Long], [pInformation)

Parameters

  • ConnectionString
    A string used to connect to the OLE DB provider where the request will sent. If a handler is used the handler may edit or replace the connection string.

  • HandlerString
    The string identifies the handler to be used with this execution. The string contains two parts. The first part contains the name (ProgID) of the handler to be used. The second part of the string contains arguments to be passed to the handler. How the arguments string is interpreted is handler specific. The two parts are separated by the first instance of a comma in the string (although the arguments string may contain additional commas). The arguments are optional.

  • lSynchronizeOptions
    A bit mask of synchronization options.

    1=UpdateTransact – Updates to the database are wrapped in a transaction. The transaction is aborted if any of the updates fail.

    2=RefreshWithUpdate – causes row statuses to be returned when neither Refresh nor RefreshConflicts is set.

    4=Refresh – the recordset is refreshed with current data from the database. Pending updates are not pushed to the database. If this bit is not set the recordset is not refreshed and any pending updates are pushed to the database.

    8=RefreshConflicts – any rows with pending changes fail to update the rows which failed to update are refreshed with current data from the database.

  • ppRecordset
    A pointer to a pointer to the recordset to be synchronized.

  • pStatusArray
    A variant used to return a safe array of row statuses for the rows affected by synchronize. Not set if none of the following synchronization options are set: RefreshWithUpdate, Refresh and RefreshConflicts.

  • lcid
    The LCID used to build any errors that are returned in pInformation.

  • pInformation
    A pointer to information error returned by Execute. If NULL no error information is returned.

Remarks

The HandlerString parameter may be null. What happens in this case depends on how the RDS server is configured. A handler string of "MSDFMAP.handler" indicates that the Microsoft supplied handler (Msdfmap.dll) should be used. A handler string of "MASDFMAP.handler,sample.ini" indicates that the Msdfmap.dll handler should be used and that the argument "sample.ini" should be passed to the handler. Msdfmap.dll will then interpret the argument as a direction to use the sample.ini to check the connection and query strings.
