title: OpenFileDialog does not show complete filename in Windows 7
body: <p>OpenFileDialog does not show complete filename in Windows 7. The problem is also reported <a href="https://connect.microsoft.com/VisualStudio/feedback/details/525070/openfiledialog-show-part-of-file-name-in-win7" rel="noreferrer">connect.microsoft.com</a>. </p>
  
  <p>There is also a work around by setting <code>openFileDialog.AutoUpgradeEnabled = false</code>. But that causes old xp style dialog. Is there any way to fix it without doing the above workaround. There is no window handle in the dialog so i cannot figure out how to add custom window message handler to do sendmessage() to fix it.</p>
  
  <pre><code>        using (OpenFileDialog openFileDialog = new OpenFileDialog())
              {
              openFileDialog.FileName = "abcdefghijklmnopqrstuvwxyz";
              openFileDialog.ShowDialog();
              }
  </code></pre>
