title: ExportAsFixedFormat
body: <p>Why the following code return invalid parameter error? Its equivalent in Delphi executes well.</p>
  
  <p>C++ Builder:</p>
  
  <pre><code>ActiveWorkSheet.OleProcedure("ExportAsFixedFormat", 0, EmptyParam,
          EmptyParam, EmptyParam, EmptyParam, EmptyParam, EmptyParam, EmptyParam,
          EmptyParam);
  </code></pre>
  
  <p>Delphi:</p>
  
  <pre><code>  oSheet.ExportAsFixedFormat(0, // xlTypePDF is constant 0
      EmptyParam, EmptyParam, EmptyParam, EmptyParam, EmptyParam, EmptyParam,
      EmptyParam, // set to True to open Acrobat
      EmptyParam);
  </code></pre>
