Run a program on server and see results on browser

All without downloading the program

[Blelisa]

Does anyone know of a tutorial or program that would enable me to do the following:
I have a program that sits on my server. It is a license generator program for my software. I want my resellers who are in another country than I to be able to go to a web page, click on license generator and be able to enter the necessary information to get back a license key from the program. Here is the caveat...I dont want them to be able to download the program. I simply want the program to run on the server, excpect the input from the reseller and than get the key and spit it back out to reseller in their browser.
I dont even know where to start with this. Anyone have any ideas?

Did you create this license software yourself? I would suggest coverting it to something like a COM component which you could then call via a web service or directly from your website code.

I did not myself develop it but I do have access to the person who did.
Do you set the program in command line? Than write asp to call it? I am relativley new too this, is there a tutorial you could point me to, to help me learn how to do this?

Well, if the program has some kind of API to access you could just reference the DLL and access its code directly. If not then I'm not sure what you can do.
