Hello Everyone!
I was wonder when you use a trail or demo controls from a
third party it comes up with a demo screen and reminding you
that you have to register or pay for it. How do you do that with your own control?

It's probably this easy:
Msgbox "YOu have to register this control, it cost you only 10000$, read the readme file"
But you need to store the date on first time used somewhere, probably best crypted in registry and then use datediff and now to calculate the evalution period

writing haskell makes your life easier:
reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13

No need for that to an ocx, you can't distribute an app with an ocx popping up annoying messages or tell them to change back the clock every time they use it
