download executables from web page

[ask_you]

i have uploaled my exe on the web server of our private net. now i want that whenever someone tries to download my exe, a pop-up box should come up which will ask for the license key. once the licence key is validated, only then the download should start. how do i implement it? Secondly since the exe will be hosted on intranet, so whenever someone tries to download my exe, i need to know the IP address of the system which is trying to download it, check whether its a valid internal address and only then ask for licence input. how do i implement it?

Hi: Regarding your first query, you can implement a login like script and only after validation of license, you can Response.Redirect to the EXE or Stream the EXE with appropriate content-type set. Regarding your second query, you can configure at the server level instead of validation of network IPs in ASP since it would be processor intensive operation.

i think i can handle the first part of the query. now, let me re-phrase my second requirement. i want that everytime my EXE starts it should first validate with the server. how do i do? any sample code?

Basically in the client workstation, each time the EXE is launched you want to check with the server. Cool. You can have a Web Service exposed through your webserver and your application can contact the same.
