Enables or disables a handler.

Syntax

HRESULT EnableHandler(
  [in] BOOL                  fEnable,
  [in] LPCWSTR               pszHandlerID,
  [in] HWND                  hwndOwner,
  [in] SYNCMGR_CONTROL_FLAGS nControlFlags
);

Parameters

[in] fEnable

Type: BOOL

TRUE to enable; FALSE to disable.

[in] pszHandlerID

Type: LPCWSTR

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

[in] hwndOwner

Type: HWND

A handle to a window that can be used by the handler to display any necessary UI. This value can be NULL.

[in] nControlFlags

Type: SYNCMGR_CONTROL_FLAGS

A value from the SYNCMGR_CONTROL_FLAGS enumeration specifying whether the enabling or disabling of the handler 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

An active handler appears in the Sync Center folder; an inactive handler appears in the Sync Setup folder.

If the specified handler returns SYNCMGR_HCM_QUERY_BEFORE_ENABLE or SYNCMGR_HCM_QUERY_BEFORE_DISABLE in the mask returned from the GetCapabilities method, the user is presented with a confirmation dialog requested before the handler is enabled or disabled. If no query UI is requested or once the user confirms the operation, the handler's Enable method is called.

If SYNCMGR_CF_WAIT is set in the nControlFlags parameter, EnableHandler does not return until Sync Center has processed this notification.

Examples

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

void 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 to enable our handler.
        hr = pControl->EnableHandler(TRUE, 
                                     s_szMySyncHandlerID, 
                                     hwnd,
                                     SYNCMGR_CF_NOWAIT);
        pControl->Release();
    }

    ...

}
