SaveTo Method

[This is preliminary documentation and subject to change.]

Binds to and saves data into the item with the specified URL. 

[Visual Basic,VBScript]
Sub SaveTo(
  ByVal SourceURL as String,
  ByVal ActiveConnection as Object,
  [ByVal Mode as ConnectModeEnum],
  [ByVal CreateOptions as RecordCreateOptionsEnum],
  [ByVal Options as RecordOpenOptionsEnum],
  [ByVal UserName as String],
  [ByVal Password as String]
)
[C++]
HRESULT SaveTo(
  BSTR SourceURL,
  IDispatch* ActiveConnection = 0,
  ConnectModeEnum Mode,
  RecordCreateOptionsEnum CreateOptions,
  RecordOpenOptionsEnum Options,
  BSTR UserName,
  BSTR Password
);
[IDL]
HRESULT SaveTo(
  [in] BSTR SourceURL,
  [in, defaultvalue(0)] IDispatch* ActiveConnection,
  [in, optional] ConnectModeEnum Mode,
  [in, optional] RecordCreateOptionsEnum CreateOptions,
  [in, optional] RecordOpenOptionsEnum Options,
  [in, optional] BSTR UserName,
  [in, optional] BSTR Password
);
SourceURL
The URL specifying where to save.
ActiveConnection
A reference to an existing ADO Connection object to use when saving. A new Connection (session) object is implicitly created if none is specified.
Mode
ADO defined access mode for the object. This value is always ORed with adModeReadWrite. That is, at least read-write access is required to save the item.
CreateOptions
Creation options for the new item. The values adFailIfNotExists and adOpenIfExists should not be used. If used, an E_INVALIDARG exception is raised.
Options
This specifies options flag(s) opening the source. Your setting is always ORed with adOpenSource.
Username
Used to pass a user name if needed for authentication.
Password
Used to pass a password if needed for authentication.

Remarks

The specified URL must identify a valid URL namespace that the OLE DB 2.5 root binder can resolve to a registered provider binder. Once resolved, the URL must conform to that provider binder's URL semantics.

The enumerated values and their semantic definitions are defined as part of the ADODB type library and documentation. Consult the ActiveX Data Objects (ADO) Version 2.5 documentation for a list of valid enumeration values and their intended purpose. Use of various enumerated values and their intended meaning is specific to a particular OLE DB 2.5 provider.

Restrictions on what types of data can be saved into a particular resource and how that data is handled by an implementation of the IDataSource interface is not part of this definition. Consult the appropriate COM class reference for further information.
