JScript does not support passing value-type arguments by reference.

Parameters

• format
  The format in which to render the report. This argument maps to a rendering extension. Supported formats include Excel, PDF, Word, and Image.

  To access the list of available rendering extensions, use the ListRenderingExtensions method.

• deviceInfo
  An XML string that contains the device-specific content that is required by the rendering extension specified in the format parameter. For more information about device information settings for specific output formats, see Device Information Settings in SQL Server Books Online.

• pageCountMode
  A PageCountMode enumeration value that specifies the page count mode.

• createStream
  A CreateStreamCallback delegate function that will be used to provide a Stream object for rendering.

• warnings
  [out] An array of Warning objects that describes any warnings that occurred during report processing and rendering.

Remarks

This method accepts a CreateStreamCallback delegate function in the createStream parameter to support custom handling of secondary streams. This method is useful for printing.

After this method completes successfully, the value of pageCountMode will be the default page count mode the LocalReport object uses when you call the GetTotalPages method. For more information, see GetTotalPages.
