Using Barcode Control SDK for VS .NET Control to generate, create, read, scan barcode image in VS .NET applications.
The Flex framework includes a pretty decent logging package that should be suitable for most requirements. To get started using the Flex logging package, begin by creating and configuring a target, as shown in Listing 6.1. Once the target is configured, add it to the system using the Log class.

Asp.net Aspx qr bidimensional barcode creatoron .net
using barcode printer for asp.net website control to generate, create qr-codes image in asp.net website applications.
With a target added, you can now begin logging. Loggers are stored by category, so you need to pass the Log.getLogger method the category you are logging for; then it will return that category s logger, as shown here:
Control qr-code image for visual basic
using visual .net topaint qr code iso/iec18004 for asp.net web,windows application
Log.getLogger( myCategory ).debug( This is a test message. ); // or _logger = Log.getLogger( myCategory ); _logger.debug( This is a test message. );
Bar Code barcode library with .net
use vs .net barcode generating toassign bar code for .net
Either of the two approaches shown above are fine; it is a personal preference. In addition to simply taking a message parameter, the Flex logger also supports specifying a format using a special notation, as shown here:
Render pdf417 on .net
using visual .net crystal toconnect pdf417 in asp.net web,windows application
var methodName:String = init ; var message:String = The application is now initializing... ; // Output: [init] The application is now initializing... _logger.debug( [{0}] {1} , methodName, message);
Draw ean 128 for .net
using barcode maker for .net vs 2010 control to generate, create gs1 128 image in .net vs 2010 applications.
Lastly, to filter output by level, you need to add a check before each logger call, as shown here:
EAN 8 drawer on .net
generate, create ean / ucc - 8 none on .net projects
if(Log.isDebug()) _logger.debug( [{0}] {1} , methodName, message);
EAN / UCC - 13 barcode library for visual c#.net
using asp.net aspx crystal togenerate ucc - 12 in asp.net web,windows application
You may prefer to build a static class that handles the process shown above for you. Listing 6.2 demonstrates such a class.

.NET WinForms code 128 printerfor .net
using barcode printer for .net winforms control to generate, create uss code 128 image in .net winforms applications.
This is a great way to get everyone that is working on a particular project to output messages that are formatted consistently. Altogether, getting your logger initialized and outputting your first message will look something like Listing 6.3.

The Logger Class in Use
package org.airbible.logging { import mx.core.WindowedApplication; import mx.events.FlexEvent; import mx.logging.Log; import mx.logging.LogEventLevel; import mx.logging.targets.TraceTarget; public class Main extends WindowedApplication { public const NAME:String = org.airbible.logging.Main ; public function Main() { super(); init(); } protected function applicationCompleteHandler(event:FlexEvent) :void { called. ); Logger.debug(NAME, applicationCompleteHandler , Method }
protected function init():void { initLogger(); addEventListener(FlexEvent.APPLICATION_COMPLETE, applicationCompleteHandler); } protected function initLogger():void { var logTarget:TraceTarget = new TraceTarget(); logTarget.level = LogEventLevel.ALL; logTarget.includeCategory logTarget.includeDate logTarget.includeLevel logTarget.includeTime Log.addTarget(logTarget); } } } = true; = true; = true; = true;
Debugging and Profiling
From here, you may wish to write your own target(s) to use instead of or in addition to TraceTarget. An example of a target that you might create is one that sends the messages over a local connection. You could then make a separate log application that displays the messages received over the local connection in a nice, stylized text field. You may even add some various controls for aiding in the sorting and filtering process.
Profiling Techniques
Profiling an application is the process of analyzing its performance. Using a number of different techniques, you can squeeze the most out of your application in terms of performance and seal any existing memory leaks. You can explore each of these techniques in the sections that follow.
Monitoring the frame rate
Depending on the type of application that you are developing, the frame rate is either very important or not important at all. A game, for example, relies very heavily on a consistent frame rate not only for the sake of visual elements, but also for the quality of game play. Other types of applications that feature lots of animations also need to pay close attention to this. On the other hand, if your application is mainly just forms and static User Interface (UI) elements, the frame rate really is not important. Assuming that you are working on an application in which you need to monitor the frame rate, Listing 6.4 demonstrates how you can accomplish this.
