问题 I am using generic code (from the iOS Fireworks demo) in a slightly changed way. I have the following in a subclass of UIView. What I want is to make the firework appear at the point the user touches (not hard) and play out for the length of the CAEmitterLayer/CAEmitterCells 'lifetime'. Instead, this is immediately starting when i add it to addSublayer -- like I am sure it is meant to. However, I would like to use it in a slightly different way. Is there a way that I can change this so there

问题 Whats the difference between DataAnnotations and Application Validation Block? 回答1: DataAnnotations is an attribute based model to 'annotate' your data and it is in the .NET framework itself.

Validation Application Block itself is a validation framework, created by the Microsoft P&P team, but it is not part of the .NET framework. It also contains attributes to 'annotate' your data and in its newest version (5.0) the

问题 Sup guys, I'm trying to do a function that calls itself but by putting everything on one block, As you can see, the following function is intended to be called an indefinite amount of times (until arcrandom returns a number lower than 50) and you should expect as an output a variable number of "RUNNING" messages, depending on chance. void (^_test_closure)(void) = ^ { NSLog(@"RUNNING"); if(arc4random() % 100 > 50) { _test_closure(); } }; _test_closure(); However, when running it, I get an EXC

问题 I’ve faced with an issue with IE6 & IE7 issue and I was hoping someone had a solution for me other than to not use IE6/7.

An yhelp would be greatly appreciated Note: I turned on borders so I could see what's happening... Demo of my issue: http://jsbin.com/ilese4/ Here's a
