Re: RE: How to create a Trial application?

Hi John,

First, I'm glad to know that my English was pretty good. Thanks.

The point is that I developed an application and still not received the money. I know that my application will run until next monday and after this... NO MORE!!! And I will fix this "bug" only if they pay me. :)

Of course that if they back the date... but they can't work this way because they need to print a voucher!!!

Reading its email I thought about another way to stop the program. I can count for a period of time with program running and after 5, 10 or 30 minutes to quit the application.

I like your way to lock the program. I'll try!

Thanks a lot!

Fábio
