how to invoke a method in a DLL

[Lloyd Dupont]

I want to create date and return them on the fly.

I wonder I I could create a DLL with some static method in it and invoke
directly with an URL of the style
http://myHost/myDll#myClass.myMethod?arg1=val1&arg2=val2

is it possible to have something like that ?
any thought ?

does it work ? (I mean could you show me a web services sample doing that ?)

I tell you my problem, I'm writting a 'preview' custom control.
basically it's an input of type image wich show the image onclick and should
display a small version of the image, for this I should set its src
property.
and here come the problem. what URL could I use ? (for the src)
I could rely on the end user to provide an URL for the preview image, but
that won't be a very powerfull preview control this way .. so I do need this
user control to provide an URL pointing to itself which return the picture.

if you have any idea ?
anyway today I made lot of test and manage to write a cgi (.exe) which could
be invoked by IE and return whatever I want.
tomorrow I will try to put my preview custom control in it, and that would
be the surprise ...
although there is the drawback I lost session management doing so and then I
can't cache the preview, so it's not good either. maybe I will end up
requiring a 'FileUtil.aspx' page to be used with the preview control, so sad
;-(

OK,
1) you can create web form that will return images by changing the
content type and write binary output you can refer to my sample (create
images for buttons)[1]. the page can take parameters as query string.

2) if you want to be more dynamic you can create your own HTTP module
and handler.
