c++ Windows开始菜单Internet快捷方式工具提示

Question

我用c++在开始菜单中为windows创建了一个internet快捷方式。一切都很好，但我如何在这个快捷方式中添加工具提示?

我找不到一些像我ShellLink::SetDescription的shell链接。

...
QString internetAddress = "http://www.blabla.de";
IUniformResourceLocator *pURL = NULL;
CoInitialize(NULL);
HRESULT hres;
hres = CoCreateInstance(CLSID_InternetShortcut, NULL,
  CLSCTX_INPROC_SERVER, IID_IUniformResourceLocator, (LPVOID*)&pURL);
if(SUCCEEDED(hres))
{
  IPersistFile *ppf = NULL;
  hres = pURL->SetURL((LPCWSTR)internetAddress.utf16(), 0);
  if(SUCCEEDED(hres))
  {
    hres = pURL->QueryInterface(IID_IPersistFile, (LPVOID*)&ppf);
    if(SUCCEEDED(hres))
    {
      hres = ppf->Save((LPCWSTR)linkFilePath.utf16(), TRUE);
      ppf->Release();
    }
    pURL->Release();
  }
}
...

您可以查询IUniformResourceLocator的IPropertySetStorage接口，然后通过该接口设置其他属性。
