ISyncMgrControl::UpdateItem method (syncmgr.h)

Informs Sync Center that properties of a sync item have changed.

Syntax

HRESULT UpdateItem(
  [in] LPCWSTR               pszHandlerID,
  [in] LPCWSTR               pszItemID,
  [in] SYNCMGR_CONTROL_FLAGS nControlFlags
);

Parameters

[in] pszHandlerID

Type: LPCWSTR

A pointer to a buffer containing the unique ID of the handler that manages the item. This string is of maximum length MAX_SYNCMGR_ID including the terminating null character.

[in] pszItemID

Type: LPCWSTR

A pointer to a buffer containing the unique ID of the item. This string is of maximum length MAX_SYNCMGR_ID including the terminating null character.

[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, UpdateItem does not return until Sync Center has loaded the specified handler and reloaded all handler and item information. If the handler is provided by a handler collection, the handler collection is also loaded to reload the handler.

Examples

The following example shows the usage of ISyncMgrControl::UpdateItem 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 properties of the item have changed.
        hr = pControl->UpdateItem(s_szMySyncHandlerID,
                                  s_szMySyncHandlerMusicContentID,
                                  SYNCMGR_CF_WAIT);
        pControl->Release();
    }

    ...

}
