[Dexter]

Hello all,
I'm building a web custom control, but i hava a problem.
In the Sub Render, i have a html code as output. All ok.

I have a other class that has a function that return a image object,
and i need to insert this image in my html of output, but it
don't has a path.

Protected Overrides Sub Render(ByVal output As System.Web.UI.HtmlTextWriter)
dim saida as string
saida = "<table>"
saida += "<img src="">" --> ???????? What i do here to show the returned
image of my Function.
saida += "</table>"
End Sub

Somebody can help me in this task?
Thanks

You can't do that. An image is an individual request and thus takes the
entire stream..you can't mix text (html) with binary (image) data.

What you can do is:

saida += "<img
src=imageGenerator.aspx?imageId=WHATEVERINFORMATIO N_YOU_NEED_TO_BUILD_YOUR_I
MAGE>";

and move your function that returns an image to imageGenerator.aspx, saving
the image to the Response.OutputStream ...

Ok karl,
this i know to do, but now, is possible to compile the assembly with a .aspx
page?
I don't want to have to distribute a .dll and a .aspx page, i want to
distribute only
the assembly (.dll).
Is possible to compile the .aspx page in a assembly?

Thanks.

The only thing I can think of is to use an HttpHandler..not sure if it'll do
the trick though, can't say I know enough to give a good answer, but
hopefully that'll give you something to try out...
