title: How to get a LPITEMIDLIST pointer according to the path of a folder?
body: <p>I want to get the system icon of a specified folder, but maybe the only way to retrieve the icon is to use SHGetFileInfo() method. The first parameter of SHGetFileInfo() method is a pointer of LPITEMIDLIST.</p>
  
  <p>If I only have the absolute path of the folder, how can I get the pointer according to the path?</p>
