Try this for your Read:
MyFileStream.Read(Buffer, 0, 65536)

Hello friends,
                  iam also going through similar kind of problem
When i try to open a pdf file in IE, it just appears blank
while in Firefox pdf file open successfully

I want to know why its not opening with IE.

Here is my code

Response.AddHeader("Content-Disposition", "inline;filename=File.pdf");

Response.ContentType = "application/pdf";

Response.WriteFile(@"c:/pb-1.pdf");

Response.AddHeader("Content-Disposition", "attachment;filename=File.pdf");

it opens the pdf file not inside IE but in Acrobat reader

iam using IE 6.0.2900 SP2 and WinXP SP2 and Acrobat reader 6

I had a similar problem this week where pdf's would  no longer render after the latest Microsoft security update was installed. People @ work who had not applied the patch did not have the problem, but a co-workwer of mine who did apply it had the same problem (although it worked fine for us in firefox).
The newsest fix may have been trying to address this issue acrobat found recently:

suffice it to say installing Acrobat reader 8 fixed my issue (and my coworkers too)

What if you don't put any Content-Disposition header at all?

yes in Acrobat Reader 8 the problem is solved.. but in my case it must work on all versions of Reader as  my application will be used by several users from their home..

Beside restricting them to download latest version of Acrobat Reader 8.. is there any other way to solve the problem????

In your second page, do you write anything to the response before trying to write the PDF?  It is possible that part of the response gets to the client before you call the ClearContent, etc and this may screw up how the client interprets the results (for example, it gets a header with a text content type or something).  For example, if you do a response.write(""); I'm pretty certain you can't do a response.redirect() and expect it to work.

You could also try to comment out everything except your conditional statement and the code that writes out the pdf (or comment out everything except the code that writes the pdf).  Slowly add code back in until it stops working and you have your problem area.

A useful link as long as we're on this topic:

I don't know if anyone has found a solution for this, but I'm using the following:

Response.AppendHeader("Accept-Ranges", "none")

This has solved the PDF streaming problem for me!!!
