ISyncMgrHandler::Enable method (syncmgr.h)

Requests that an active handler be enabled or disabled. An enabled handler can be synchronized and a disabled handler cannot.

Syntax

HRESULT Enable(
  BOOL fEnable
);

Parameters

fEnable

Type: BOOL

TRUE to enable; FALSE to disable.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

A handler must set the SYNCMGR_HCM_CAN_ENABLE and SYNCMGR_HCM_CAN_DISABLE flags for the Enable and Disable entries to appear on the handler's shortcut menu when the handler is shown in the Sync Center folder. Choosing to enable a handler means that it can be synchronized; choosing to disable a handler means that it cannot.

Sync Center calls this method in the following two instances.

  • When the user selects the handler in the Sync Center folder and launches its Enable task. If the handler supports the SYNCMGR_OBJECTID_QueryBeforeEnable object, this method is only called if the UI operation was successful.
  • When the user selects the handler in the Sync Center folder and launches its Disable task. If the handler supports the SYNCMGR_OBJECTID_QueryBeforeDisable object, this method is only called if the UI operation was successful.
If the handler does not need to perform any actions when it is activated, it can return either S_OK or E_NOTIMPL as shown in the example below.

Examples

The following example shows a simple implementation of this method.

STDMETHODIMP CMyDeviceHandler::Enable(__in BOOL fEnable)
{
    return E_NOTIMPL;
}
