  Problem

  To make a Google map component in Flex. Also provide a marker capability, such that on every double click the marker is added on Google map. This can be used to develop mesh-up application using googlemap with some other API (like yahoo search)

  Solution

  On each double click on the map, marker is added to Google map thus creating a overlay of markers on top of the Google map. Please include the SWC file provided here with as an attachment.

  Problem

  We know how to do it with functions how to set a default value when nothing comes through but what about variables such as in scenarios of flash vars where we just don't know until run time if we are going to get the variables or not.

  Solution

  Like anything cool in the world of programing there are a few options. The first is a traditional if statement asking our variable if its empty or not but then that wouldn't be such a cool trick if that was the full solution. come join in this is really cool...

• EventController: Event management made easy. A leak free event experience for AS3

  Problem

  Working with events in AS3 isn't as easy as it used to be in the past. While you need to monitor every event in your application there is no real easy way to do it without manually remembering all of your events and remembering to remove them on a one by one bases(ohi so much work...). With all the new features and powers of AS3 came a lot of leg work. So many classes out there tried to tackle this issue from many interesting and different directions. But most of them demand a large learning curve and a big shift in the way you would interact with your code, some through a framework that locks you into a development style, some changed the way flash handles events.

  Solution

  Essentially Event Controller is an easier way to keep track of events in actionscript 3. Event Controller is a simple extension to your normal workflow that allows you to easily tag, group and remove any and all events, pause events and restore them when you want them back and more. We know that there are many great solutions out there from very talented people. But we wanted to bring out another option the most simple one we could think about and we are with our ears to the community(so far in our 3rd revision) to making it even easier. The goal is to create the most simple yet feature rich event hub. Let unknown leaks be a thing of the past by taking our library out for a spin.

• Read/Write to serial port from Adobe Air

  Problem

  You need to communicate with device (in my case a biometric scanner) via RS232. This involves interpreting the serial output from the device and sending the device commands as required.

  Solution

  Use the freeware application 'Serproxy' to redirect serial communication with the device via a network socket connection to my Air application.

• Communicating between JavaScript and the Creative Suite SDK using HostObject

  Problem

  You need the ability to call JavaScript functions from the Creative Suite SDK (CS SDK) and vice versa.

  Solution

  In the following code, I'll explain how to use HostObject to communicate between JavaScript and the CS SDK. This will involve embedding your JavaScript in your swf and defining interfaces for communication between the two different contexts. Note, this recipe will not cover using CSXSInterface.evalScript but that is another viable method for communicating from the CS SDK to JavaScript.
