MS SQL, Parse URL procedure
Very often, I need to parse URLs into different parts, here is a quick funciton I wrote to do that. Obviously, you can make it more robust if you want.
-- Right now, it support the following parsing of a URL

QR Code that supports limited use or expiration date
We just created a new QR code service that can be used to redirect users to a web page, with a twist. You can set a limit or an expiration date for the redirect. Once the limit or expiration date is reached, we will redirect the future user to the URLs you specified when setting the limit or expiration date.
Enjoy! Try it now!

QR code for Restaurants
Hi, All:
I have developed a QR code application for restaurants. QR codes are 2-dimensional bar codes that can be read by smart phones. The code contains a web page URL users can browse with their smart phones. The web page could also contain restaurant phone number that can be called with a simple click.
I think it is perfect for take-out menus. The main advantages are:
- You can save money print outs. As more people using mobile webs, there is less need for paper based take-out menus.
- Web pages with a “click-to-call” function will be very convenient to all dinners on the go.
- With QR code, customers don’t need to manually type the web URL into their phones. They just scan it to browse the content, with the option to bookmark it for future use.
- If you already have a web page for takeout menu, you can use our free Goo.gl service to generate QR code for the menu URL page.
- You can post the QR code in your restaurants so that customers can scan it and bookmark the web page.
As a new service promotion, we will create mobile friendly takeout menus with QR code technology for you. You just need to give us your existing web page URL or menu list. With only $10 per year, you can enjoy the service with minimum efforts.
Thank you. Please email me at uptier@gmail.com if you have any questions.
