Hi,

Does somebody have a working project-example to show image on a Web Form
writing the byte[] to a http stream and assigning the source of the image on
the form to this url?

I can't understand some logic, how can we write to a http stream and use
this stream in a client browser showing it as a picture.

I saw few examples on the Internet, but no one alive project, to compile and
see.

By webform are you referring to ASP.net? Or what type of service are you
using for the HTTP server?

Hi Chad,

You know the task is pretty easy if know how to do that. In few words I need
to extract an Inage from a database and show on the form. I found a few
solutions on the internet about the same - Response.BinaryWrite() but it
doesn't work for me because I didn't find a whole working solution, just
fragments of examples. And I can't understand how to write this example to
get a working project.

As I understood I need to create an aspx web form and assign a type to a
image type, but how can I get the image that should be written to the http
stream? Did you see a good explanation of that? When I read an example
somewhere on the Internet it looks easily but I didn't see a whole project
to run and understand how it works.

Thanks.

Dmitri

An easier way is to write it to a temp file. Then make a URL to that, and let
IIS take care of streaming it.

I think it might be better to skip the webform, and just use a HTTP handler
instead. You would catch your URL, set the content type and just write
directly.

If your open to 3P solutions, IntraWeb extends ASP.net and this is one of the
features it offers is a DBImage control.
