display a file to the browser using stream

[CodyGen]

Hello, I'm using the browser control of vs.net 2005 and what I am trying to do is to display a file like an image via stream and not using the physical file path. Can this be done? I have tried using the DocumentStream property but only displays the file in garbled text. Many thanks. :confused:

Using the WebBrowser.DocumentStream property is correct but it depends on what your stream contains. What are the contents of your stream? The stream can only contain plain text. Anything else will just be interpreted as plain text, so binary files will not be interpretted or handled correctly. This posting is provided "AS IS" with no warranties, and confers no rights.

I guess I am out of luck since I am trying to display a stream of image and a pdf. Oh well, thanks. :-)

You're not out of luck - there's just not a simple solution. The WebBrowser control is an ActiveX container and hosts things like MSHTML (the rendering engine for IE), Word, Acrobat (Reader), etc. It involves getting RCWs (runtime callable wrappers - a managed interface wrapping a native COM interface) and loading an IPersistFile interface (or a small handful of other, similar interfaces). Of course, you could always just navigate to the file and IE (a la the WebBrowser control) will take care of the rest. For the former method, search for "WebBrowser.DocumentStream" and you'll find some helpful tips. This posting is provided "AS IS" with no warranties, and confers no rights.
