ISyncMgrHandlerInfo::GetTypeLabel method (syncmgr.h)

  • Άρθρο

Gets a label for the handler type. This typically provides the model of the device or an equivalent handler-specific identity string.

Syntax

HRESULT GetTypeLabel(
  [out] LPWSTR *ppszTypeLabel
);

Parameters

[out] ppszTypeLabel

Type: LPWSTR*

When this method returns, contains a pointer to a buffer containing the label string.

Return value

Type: HRESULT

Returns S_OK if successful, or an error value otherwise. If the method fails, ppszTypeLabel contains an empty string.

Remarks

The label value is displayed as the System.Sync.HandlerTypeLabel (PKEY_Sync_HandlerTypeLabel) property in the folder UI. Sync Center calls this method whenever the UpdateHandler method is called.

The handler is responsible for allocating the string buffer pointed to by ppszTypeLabel through CoTaskMemAlloc. Sync Center deallocates the string buffer through CoTaskMemFree.

Examples

The following example shows an implementation of this method.

STDMETHODIMP CMyDeviceHandler::GetTypeLabel(__out LPWSTR *ppszTypeLabel)
{
    LPWSTR pszTypeLabel = NULL;

    HRESULT hr = LoadStringAlloc(g_hmodThisDll, 
                                 IDS_HANDLER_TYPE_LABEL,
                                 &pszTypeLabel);
    if (SUCCEEDED(hr))
    {
        // Duplicate for the caller.
        hr = SHCoAllocString(pszTypeLabel, ppszTypeLabel);
        LocalFree(pszTypeLabel);
    }

    return hr;
}
