Using An External Program To Check User Authentication/Usergroup Permissions

[cheech47]

Hello,

I am trying to set up an external program that will open if a member is registered to the vbulletin forum and in the correct usergroup.

The idea is that a user enters their username and password and the program will launch if the user is either an admin, mod or a subscribed member.

In the past I have used a launcher that does something similar to this but I have to manually add everyones username and password to a separate file for this to work, just wondering if there's anyway I can use vb to authenticate this for me rather than having to remove/add folk everytime someones subscription runs out or a new member subscribes

Thanks
