title: Powerpoint ExportAsFixedFormat - Hide "Publishing..." progress dialog
body: <p>I've written a class that converts documents in powerpoint format to a pdf document with the help of interop methods from Office14.
  Everything works fine and I get exactly the result I want.</p>
  
  <p>The problem I have is the dialog that pops up when calling the method:</p>
  
  <pre><code>PowerPoint.Presentation.ExportAsFixedFormat
  </code></pre>
  
  <p>The dialog displays the export progress, has the title "Publishing..." and a Cancel button. (Cannot use images in my posts yet...)</p>
  
  <p>I am wondering if there is any way to hide this dialog during the export process.</p>
  
  <p>I've already tried the following approaches but without any success:</p>
  
  <pre><code>PowerPoint.Application app = new PowerPoint.Application();
  app.DisplayDocumentInformationPanel = false;      
  app.DisplayAlerts = PowerPoint.PpAlertLevel.ppAlertsNone;
  </code></pre>
  
  <p>Thanks for your help.</p>
  
  <p>Best Regards,<br>
  Steffen</p>
