Internet Explorer problem after upgrade from Visual Studio 2003 to Visual Studion 200

[cacd1971]

Hi,

I use following C# code behind an aspx file to send a *.pdf file to the
Internet Explorer.
The variable "buffer" is of type byte[] and is filled with the contents of a
*.pdf file.

this.Response.ClearHeaders();
this.Response.Clear();
this.Response.ContentType = "application/pdf";
this.Response.BinaryWrite(buffer);
this.Response.End();
 

All works fine for years. When the aspx file is requested, the acrobat
reader is activated and the pdf file is shown.

Now I have installed Visual Studio 2005 parallel to Visual Studio 2003. All
seems to run as expected, except the pdf file is not shown anymore. The
Internet Explorer 6 shows only a white background, but does not start
acrobat reader. When I try to see the source text, I get an error message,
that the "xml source cannot be shown".

After deinstalling Visual Studio 2005 by Windows System Recovery all runs
normal again.
Any idea?

I would suggest using telnet (if possible) or even (gah!) firefox to see what the RETURNED headers are when you request the page that should be a pdf.

You clear all the headers out, but what the definition of "clear" is might be different depending on which version of VS you have, and one of the headers might be getting mangled.

I do something similar (although I require mine to popup with a "save open cancel" dialog)

Response.Clear();
Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
Response.ContentType = "Application/PDF";
Response.AddHeader("content-disposition", "attachment; filename=" + System.IO.Path.GetFileName(getfile));
Response.WriteFile(getfile);//I send directly from a file, but you should be able to just send the bytes
Response.End();

It appears that IE6 is not the culprit. I would think that there is a referencing problem that is not explicit. The difference may be in the framework.
