Thread: Can you pass a dll url parameters?

I have a third party dll that I need to call. The instructions
came with an example server link, but it does not work and
the person is hard to get in touch with. I haven't seen this
before:

Code:

Please excuse the long delay of my reply. Here is a web server library
that allows drawing of 2D structures. The library requires an ISAPI
capable web server, e. g. Microsoft IIS 5 or 6; it returns a picture
that
is embeddable in other pages.

An example server for your testing purposes is available at

http://54.74.133.179/pic3.dll/m?l=c1ccccc1&w=300&h=200

The library can be called with the following arguments:
l: SMILES string
w (optional) : width, pixels, between 10 and 500, default 300
h (optional) : height, pixels, between 10 and 500, default 200

It looks like they're passing url arguments directly to the dll. Is this possible? This is all I have to go on.

I have not done much with dlls...
but i can tell you that for example the dll that loads error and about pages in IE shdoclc.dll takes arguments.. it is used like this...
if you run .. (in win98)
res://c:\windows\system\shdoclc.dll/"pagename.htm"

so pagename could be dnserror.htm, http_404.htm or about.dlg or whatever is in shdoclc.dll..

i just know this because of a project i did on that dll recently.. im sure someone will give you a more general answer..

my final answer would be "yes" though..

Thanks, that makes sense and gets me going in the right direction.

Hi-
I'm not 100% on this, but I think this is related to the behavior of CGI. I think the way it works is, your web server will set whatever comes after the requested resource in the url (which is pic3.dll in this case) as an environment variable named QUERY_STRING (m?l=c1ccccc1&w=300&h=200). the dll must know how to parse & make use of it.

I would look for the CGI specifications.
