ISyncMgrControl::UpdateHandlerCollection method (syncmgr.h)

Instructs Sync Center to reenumerate the handler collection, or informs it that properties of a handler in the handler collection have changed.

Syntax

HRESULT UpdateHandlerCollection(
  [in] REFCLSID              rclsidCollectionID,
  [in] SYNCMGR_CONTROL_FLAGS nControlFlags
);

Parameters

[in] rclsidCollectionID

Type: REFCLSID

A reference to the handler collection's CLSID.

[in] nControlFlags

Type: SYNCMGR_CONTROL_FLAGS

A value from the SYNCMGR_CONTROL_FLAGS enumeration specifying whether the update should be performed synchronously or asynchronously.

Return value

Type: HRESULT

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

Remarks

If SYNCMGR_CF_WAIT is set in the nControlFlags parameter, UpdateHandlerCollection does not return until Sync Center has loaded the specified handler collection and reloaded all handler and item information.

Examples

The following example shows the usage of ISyncMgrControl::UpdateHandlerCollection by a handler's procedure.

void CMyDeviceHandler::MiscProc(...)
{
    ...

    // Get the Sync Center control object.
    ISyncMgrControl *pControl = NULL;
    
    hr = CoCreateInstance(CLSID_SyncMgrControl, 
                          CLSCTX_SERVER, 
                          IID_PPV_ARGS(&pControl));
    if (SUCCEEDED(hr))
    {
        // Tell Sync Center that a new computer has been added.
        hr = pControl->UpdateHandlerCollection(CLSID_FRSHandlerCollection,
                                               SYNCMGR_CF_NOWAIT);
        pControl->Release();
    }

    ...

}
