Hi,

If it is ASP .Net just add response.redire ct("The PDF file path") in the code

I did not see anyone actually answering this question.

I thought if I provide my current solution, I might get some constructive feedback and perhaps some assistance.

While the following ASP.NET 2.0 (2005 SP1) w/ VB.NET 2005 SP1 solution does provide a PDF rendering of the oracle stored blob PDF file, I'd like to display the PDF reader within my current page template - In Classic ASP I would do this by utilizing a report reader object.

How do I do this in ASP.NET 2.0?

If you have a sample from that language would work for me too as I can and do read, understand and develop in C#. (I do not currently have any paying customers who develop in C#, but I do use it.)
