I am sure that most readers of this site have at one point or another noticed my RegularExpression articles. Well this past week I was looking for a very specific regular expression and thought I would share it with you. The following regular expresion is used to validate a GUID value for user input. You can use this to ensure that product keys and other GUID values that you are using are in the proper format.

^(\{){0,1}[0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12}(\}){0,1}$

So yesterday I decided to replace my computer system, and today now that it is running it is totally amazing. The system is so fast and quite it is not even funny. I built the system myself using stuff purchased from Tiger Direct's outlet store in Naperville, IL and from a CompUSA in Naperville, IL that was going out of business! That will teach me to go to Chicago for a weekend!

The system has the following specs.

-Intel Core 2 Duo 2.13 Ghz Processor
-2 Gb DDR2 800 RAM
-1 10,000 74Gb SATA Hard Drive
-1 320Gb SATA 3.0Gb/sec Hard Drive
-256 Mb ATI Radeon X1300 graphics card (I don't do PC Games)
-DVD Burner with LightScribe
-One really massive ThermalTake CPU cooler!

It is amazing how my multi-taking actually works now, I can have multiple large applications open and instantlly switch between them without any difficulties at all!

Just thought I'd share!

(Remember, my company is in the business of building a custom system for you, contact us for details!)
