[flexcoders] Re: access mdb files with flex 3 reside in same directory
Flex can't natively connect directly to a database. There needs to be some sort of middle layer. (AIR apps can connect directly to SQLite, though.) For the Access DB I inherited, I ended up migrating the whole thing to MS SQL and then created web services. Then I use Flex's web service functionality to send/receive XML Soap messages. Works great. Technically, I could have created web services to hit up the Access DB, but for that much work, it was easier just to migrate to MS SQL and use the existing web service layer already in existence. --- In flexcoders@yahoogroups.com, xamkan xam...@... wrote: Is there any way having flex to access data within a .mdb file which reside in the same computer?

[flexcoders] Re: From your own experience how long does it take to learn AS3?
Don't worry about having to refer back to the materials. I'm almost a year into programming with AS3 and even though I've got a BS in IT and can program in a few other languages, I still have to refer to AS3 materials quite regularly. I'm betting it's the same case for a lot of developers unless all they do is rehash out the same code and project types over and over. Like the other post says... work in small chunks. But also be sure to comment your code. You never know when you'll want to use that code again in the future. For example, this last application I built, I would just focus on each custom component until I had it dialed in. Each one had it's challenges and in the future, those things will be a lot easier now that I've got some examples to reference back to. Likewise, there were things I just breezed through because I just recycle code from other projects when those parts were serious challenges in the past. 4 Weeks in isn't enough time to master anything. --- In flexcoders@yahoogroups.com, ellistein52 ellistei...@... wrote: I have no background in programming , I am close to 54.I am following some AS3 Lynda.com Essential Training.

Hello,
I am having a question what the best approach is to convert existing XML data
to a object graph of value objects. I have spend quite some time to fix a
memory leak in my existing parsing practice and I am curious how others solve
this problem.
My common approach is to create a class such as EventReader and
EventItemReader class which is responsible for the parsing of the specific
XML element and return the appropriate value object. But somehow this code is
leaking like a mad dog (200kb per time) while the XML file is only 16kb. Now
I have currently rewritten it so that just using simple strong typed objects.
But I would love to find out what I am doing wrong in my current approach and
how to solve it. Because it makes it easier to reuse the parsing code/logic.
For example, normally, I use the approach of creating a public class with a
few public variables like this:
public class EventItemVO {
public var eventDate: Date;
public var eventName: String;
public var location: String;
}
and then I am having code like this to parse it:
try {
var xml: XML = new XML( loaderContent );
var parser: EventItemXMLReader = new EventItemXMLReader( xml );
parser.parse();
} catch (e: Error) {
trace(Error occured while parsing);
} finally {
parser = null;
xml = null;
}
in the EventItemXMLReader-class I then return an instance of the
EventItemVO-class
Somehow this leaks and while I do the same stuff in the onComplete-handler of
the Loader and do:
array.push( {eventDate:date, eventName:name, location:location} );
The memory leak disappears. I would expect their is some reference kept alive
but I am having a hard-time finding the reference which keeps it from garbage
collecting it all.
How do you parse XML and convert it in value objects?

Why can't you learn both at the same time? Flex by itself is all nice and dandy but the power comes from being able to create cross-browser, desk top deployable front-end to business processes and data. Techincally, the business logic can be built into Flex for a lot of stuff, but it's actually better to do that elsewhere like a middleware between the data and front end.

[flexcoders] Re: How long does it take to learn Flex and get a job?
One thing to consider is 1 year of experience or 1 month of experience repeated for 12 months. Big difference. What I mean is that learning the syntax and usage of Flex is one thing. Creating Flex apps to handle real world problems is another thing entirely. Most tutorials that have you building photo browsers don't go very far in terms of business needs such as dealing with databases, user authentication, version control, blah blah blah. Also, are you looking to specialize in a specific area? Websites vs. UI interfaces to large enterprise SOA deployments, etc. I suggest learning other programming basics to go along with your Flex learning. Java or C#.net would be good and both are pretty similar. JavaScript, XML, and (X)HTML are good skills to have as well. Another suggestion is to look through the help wanted ads in your area and see what skills people are looking for. Around here Flash developers with strong AS3 skills are in high demand. Most of the jobs requiring Flex I've seen require MVC skills and strong Java skills with Spring/Hibernate/etc. The other types of jobs requiring Flex usually also require strong AJAX/JavaScript/jQuery skills.

MA won't start until the 20th day into the data set.
If you're using a static dataset, you could do the calculation in Excel
and then save the entire datset as XML and just bring that into flex and
plot the MA from the existing values.

[flexcoders] Can't bind XMLListCollection to Datagrid
I changed my webservice call to return e4x but I can't get the
XMLListCollection to bind to the datagrid.
Here is the pertinent AS code:
[Bindable]
private var Employees:XMLListCollection;
private function submit():void
{
EmployeeWS.GetAllEmployees();
}
private function resultHandler(event:ResultEvent):void
{
var xmlResult:XMLList = new
XMLList(event.result);
var Employees:XMLListCollection = new
XMLListCollection(xmlResult.children());
trace(Employees);
}
Here is how the trace returns the XMLListCollection data:
datas6:Employee xmlns:datas6=DM
xmlns:soapenv=http://schemas.xmlsoap.org/soap/envelope/;
datas6:EmployeeID3/datas6:EmployeeID
datas6:EmployeeLastNameBadham/datas6:EmployeeLastName
datas6:EmployeeFirstNameJohn/datas6:EmployeeFirstName
datas6:EmployeeMiddleNameC./datas6:EmployeeMiddleName
datas6:PositionTitleData Manager/datas6:PositionTitle
/datas6:Employee
datas6:Employee xmlns:datas6=DM
xmlns:soapenv=http://schemas.xmlsoap.org/soap/envelope/;
datas6:EmployeeID4/datas6:EmployeeID
datas6:EmployeeLastNameBui/datas6:EmployeeLastName
datas6:EmployeeFirstNameTai/datas6:EmployeeFirstName
datas6:EmployeeMiddleNameTan/datas6:EmployeeMiddleName
datas6:PositionTitleInserter Operator/datas6:PositionTitle
/datas6:Employee
Here is the datagrid code:
mx:DataGrid id=myGrid dataProvider={Employees} height=272 y=10
width=603 x=167 borderStyle=outset
mx:columns
mx:DataGridColumn headerText=Last Name
dataField=EmployeeLastName/
mx:DataGridColumn headerText=First Name
dataField=EmployeeFirstName/
mx:DataGridColumn headerText=Position
dataField=PositionTitle/
/mx:columns
/mx:DataGrid
I've been spinning my wheels with this for 2 weeks now. It's probably
something simple, but I can't figure it out after googling non-stop every damn
day. Any help is greatly appreciated.
[flexcoders] Re: Question?? Best method for plotting a Moving Average
How are you receiving your price data to plot? Price feed? Static file? What
you could do is create a function to loop through the array and perform the
moving average calculation and add the result as an extra column in the
array. Are you plotting the full historic price data set? If so, your MA will
begin at the nth bar where n is your MA period setting. eg.. a 20 day MA won't
start until the 20th day into the data set.
If you're using a static dataset, you could do the calculation in Excel and
then save the entire datset as XML and just bring that into flex and plot the
MA from the existing values.

Re: [SPAM] [flexcoders] Web Service not returning all XML elements.
Thanks for the reply. After doing some searches, I see you've answered this question a few jillion times. :) --- In flexcoders@yahoogroups.com, Tracy Spratt tr...@... wrote: The default resultFormat, object causes Flex to try to convert the xml into a tree of dynamic objects. This is somewhat of a blackbox process and you have no control over it. It is also the worst of both worlds; Dynamic objects have performance issues, (as does xml) and searching/filtering that object tree is much harder than using e4x expressions. Best practice is to get your data as e4x, then process it yourself into an ArrayCollection of strongly typed value objects.

[flexcoders] Re: Flex with .Net
WebOrb is pretty sweet. I did run into some problems where our backend data wasn't setup very well and I couldn't assign table relations in WebOrb. Workaround was using views and stored procedures. I'm currently playing around with WSO2's Web Service Application Server (http://wso2.com). It makes exposing data as web services very easy and very fast. It's a good alternative for those that don't want to use .net. It's also opensource and free which is a huge bonus as well. :) --- In flexcoders@yahoogroups.com, MicC chigwel...@... wrote: We have just switched from FlexSQL web service ($19.00) to WebOrb.
