There is no way to be notified on uncaught exceptions in Flex 3. Adobe are aware of the problem but I don’t know if they plan on creating a workaround. The only solution as it stands is to put try/catch in logical places and make sure you are listening to the ERROR (or FAULT for … Read more
Generally one cannot use SQL parameters/placeholders for database identifiers (tables, columns, views, schemas, etc.) or database functions (e.g., CURRENT_DATE), but instead only for binding literal values. With server-side support for parameterized (a.k.a. prepared) statements, the DB engine parses your query once, remembering out the peculiars of any parameters — their types, max lengths, precisions, etc. … Read more
This is my generic solution for the problem (I have blogged about this here): var toFixed:Function = function(number:Number, factor:int) { return Math.round(number * factor)/factor; } For example: trace(toFixed(0.12345678, 10)); //0.1 Multiply 0.12345678 by 10; that gives us 1.2345678. When we round 1.2345678, we get 1.0, and finally, 1.0 divided by 10 equals 0.1. Another example: … Read more
The syntax is a little different for URLRequest, but the idea’s the same: private function doWork():void { var req:URLRequest = new URLRequest(“http://yoursite.com/yourservice.ext”); req.method = URLRequestMethod.POST; req.data = new URLVariables(“name=John+Doe”); var encoder:Base64Encoder = new Base64Encoder(); encoder.encode(“yourusername:yourpassword”); var credsHeader:URLRequestHeader = new URLRequestHeader(“Authorization”, “Basic ” + encoder.toString()); req.requestHeaders.push(credsHeader); var loader:URLLoader = new URLLoader(); loader.load(req); } A couple of … Read more
If FlexContext is not available: Solution 1: inside method (>= Spring 2.0 required) HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()) .getRequest(); Solution 2: inside bean (supported by >= 2.5, Spring 3.0 for singelton beans required!) @Autowired private HttpServletRequest request;
Mate is my pick. The first and foremost reason is that it is completely unobtrusive. My application code has no dependencies on the framework, it is highly decoupled, reusable and testable. One of the nicest features of Mate is the declarative configuration, essentially you wire up your application in using tags in what is called … Read more
-xms is the start memory (at the VM start), -xmx is the maximum memory for the VM eclipse.ini : the memory for the VM running eclipse jre setting : the memory for java programs run from eclipse catalina.sh : the memory for your tomcat server
The theoretical answers from everyone else are all neat, but let’s be pragmatic. ActionScript provides the tools you need so that you don’t even have to write a loop in this case! First, note that Math.min() and Math.max() can take any number of arguments. Also, it’s important to understand the apply() method available to Function … Read more
Tracking it down At first I thought this was a coercion bug where null was getting coerced to “null” and a test of “null” == null was passing. It’s not. I was close, but so very, very wrong. Sorry about that! I’ve since done lots of fiddling on wonderfl.net and tracing through the code in … Read more
