IOleLink::SetUpdateOptions (Windows Embedded CE 6.0)

1/6/2010

This method specifies how often a linked object should update its cached data.

Syntax

HRESULT SetUpdateOptions(
  DWORD dwUpdateOpt
);

Parameters

• dwUpdateOpt
  [in] Value that specifies how often a linked object should update its cached data. The legal values for dwUpdateOpt are taken from the enumeration OLEUPDATE.

Return Value

This method supports the standard return value E_INVALIDARG.

If the method succeeds, the return value is S_OK.

Remarks

The default update option is OLEUDPATE_ALWAYS. The linked object's implementation of the IPersistStorage::Save method saves the current update option.

If OLEUDPATE_ALWAYS is specified as the update option, the linked object updates the link's caches in the following situations:

• When the update option is changed from manual to automatic, if the link source is running.
• Whenever the linked object binds to the link source.
• Whenever the link source is running and the linked object's IOleObject::Close, IPersistStorage::Save, or IAdviseSink::OnSave implementation is called.

For both manual and automatic links, the linked object updates the cache whenever the container application calls the IOleObject::Update or IOleLink::Update method.

Notes to Callers

Your container application should call IOleLink::SetUpdateOptions when the user changes the update option for a linked object.

The user selects the update option for a linked object using the Links dialog box.

Requirements

Header	Oleidl.h, oleidl.idl
Library	ole32.lib, uuid.lib
Windows Embedded CE	Windows CE 3.0 and later
