• Simple regular expression for decimal numbers?

  - by finch

  I know this may be the simplest question ever asked on Stack Overflow, but what is the regular expression for a decimal with a precision of 2? Valid examples: 123.12 2 56754 92929292929292.12 0.21 3.1 Invalid examples: 12.1232 2.23332 e666.76 Sorry for the lame question, but for the life of me I haven't been able to find anyone that can help! The decimal place may be option, and that integers may also be included.

• Android: ScoreNinja is only displaying 1 highscore....

  - by Dave B

  Hi All, I am trying to implement ScoreNinja into one of my apps. It all seems to work, but when I submit a score it replaces the current #1 score with any that I supply, even it is lower. This means that only one score is ever displayed. Anyone got any idea what I'm doing wrong? I have e-mailed the dev but he/they haven't responded. Thanks in advance for any info on this, most appreciated! Dave B

I am pretty sure I want to use CultureInfo.InvariantCulturewhere ever code analysis has detected it is missing on Convert.ToString operations. Is there anyway to get VS to automatically fix warnings of this type?

• Better alternative to autonumber primary keys

  - by Comrad_Durandal

  I am looking for a better primary key than the autonumber data type, namely for the reason that it's limited to a long integer, when I really just need the field to reflect a number or text string that will never ever repeat, no matter HOW many records are added or deleted from the table. The problem is I am not sure how to implement something like turning the current date and time into a hexadecimal string and using that as a unique field I can use as a primary key. Am I just being too paranoid about running out of space?

I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?
