title: generating barcode as an image, and embed it to an rdlc
body: <p>First, I'd like to describe my current situation.
  I have an RDLC whose data is taken from a dataset "ds" using Stored Procedure "sp". Lets say that from "ds" I can get a field of type String called "bar_code", and in turn can be used in a placeholder combined with a 3of9 font to generate the barcode.</p>
  
  <p>Now, I'd like to obtain the same result, but using another method which, given a string, will return an image of barcode in BMP or JPEG format. This method is already described at <a href="http://www.techrepublic.com/blog/howdoi/how-do-i-generate-barcodes-using-c/173" rel="nofollow">http://www.techrepublic.com/blog/howdoi/how-do-i-generate-barcodes-using-c/173</a>. </p>
  
  <p>My question : is it possible to write the method in the ReportViewer code behind (.aspx.cs) ?
  If it is possible, how can I pass that "bar_code" into this method and then embed the result (the JPEG or BMP) into the RDLC ?</p>
