Looking for a component to validate a license key...

[Jéjé]

Hi,

I want to integrate into some components (webcontrols, custom DLL, custom
command lines tools...) a license validation.

The license will be attached to the client's name and the primary hard drive
ID of the customer computer. (or any combination to make sure that the tools
are installed on 1 computer only)
For Each new client or new server deployed, the customer must ask us, then
we generate a key.

Any sample code for this?

thanks.

Jerome.

I think that this is not a good solotion if you don't have enough money to
provide a 24/7 support hotline . Harddisks are often replaced because of
a defect.

..NET's licensing mechanisms:

the number of client is limited (10 to 50).
and generally we do the installation of the servers.

but we want to secure some part of our applications in case of...

so the support is not an issue.

I have to call this key validator from VBScript code as well as from .Net
code.
From a VBScript code point of view its just a call like:
Dim obj
Set obj = CreateObject("XXXX.XXXX")
if obj.KeyValid() then
-- do something
else
-- Raise error
end if

This VBScript code is embedding in a scripted code.
