[SOLVED]How to do require admin from a button?

Alloha,

I was wondering if it's possible to get admin login screen (#requireadmin) when i press a button?

cause i am busy with a simple tray program and when i am at work i need admin rights from time to time and not when i am at home so was wondering if this was possible and so how to do it?

if u need any code just ask:)

Thanks in advance ^^
