title: Trying to save thumbnail in .NET, only getting file logo
body: <p>so following the directions <a href="https://stackoverflow.com/questions/1439719/c-sharp-get-thumbnail-from-file-via-windows-api">here</a>, I re-created the following 3 lines in VB.NET</p>
  
  <pre><code> Dim shellFile As ShellFile = shellFile.FromFilePath(tmpFile)
   Dim shellThumb As Bitmap = shellFile.Thumbnail.ExtraLargeBitmap
   shellThumb.Save("C:\Users\erizvi\Desktop\thumb", ImageFormat.Bmp)
  </code></pre>
  
  <p>However, when I execute these lines, all I get is a thumbnail of the 'word' logo, rather than the actual file, can anyone tell me why?</p>
