Re: [flexcoders] Drag And Drop Tree
Hi Alex,
I can move simple leafs from the root under a folder with no custom handlers,
if the folder is open. However the thing is that I need to just put (maybe just
copy not move) the item let's say for argument sake node label=Sent/
under Inbox folder. I cannot do that unless the sent is under some folder
and move it with the folder, because otherwise the DragSource seeems to return
an item but I cannot get the data from that item. So I end up dropping an empty
item. However as said before If I move/copy a folder with items around it works
fine ... The same happends with the drag complete handler, for just one item
the drags source traces out to blank event though the length is 1.

Setting breakpoints in drag/drop generally doesn’t work because
you tend to release the mouse in order to dig through the debugging info and
when you resume the drag is cancelled.
Remove the custom drag event handlers and try with simple data
and see if it works. We definitely tested drag/drop in Tree so basic cases
work. One trick for Tree is that what happens on drop is different than in
List. The node is removed before it is added in Tree, and sometimes that is
done
in dragComplete handler instead of dragDropHandler

[flexcoders] Re: LCDS - adding a new Item using createItem()
I had the same problem and I ended with the following solution:
Add an event listener on your collection like this:
groups.addEventListener(CollectionEvent.COLLECTION_CHANGE,
onDataChanged);
In the onDataChanged function, look if the 'kind' property of the
event is CollectionEventKind.UPDATE.
Then you can find the id with something like that:
if (ev.items.length 0)
{
var pce:PropertyChangeEvent = ev.items[0] as
PropertyChangeEvent;
var id:Number = pce.currentTarget.id;
}
Hope it helps,
Benjamin.

Re: [flexcoders] flex not seeing method
I don't know if this is related, but there is one problem with the name of
the event. The event is downloadresizeevent, while in the meta declaration
and the event handler you are calling it DownloadResizeEvent.
You will have either to change the event's name with:
public static const DOWNLOADRESIZE_EVENT:String = DownloadResizeEvent;
or correct how you reference it:
snip
mx:Metadata
[Event(name=downloadresizeevent, type=elib.event.DownloadResizeEvent)]

RE: [flexcoders] NPE on ToolTipManagerImpl/reset()
Hi
I am reopening this thread. I am unable to get around this NPE issue. I
tried to do the following
Set the visibility of ToolTipManager.currentTooltip to false (instead of
destroying it)
Disable the tooltip when I make a service call and enable it on response.
However, I still get the exception stated in my earlier mail below. The
exception occurs either on mouseOut or mouseOver tool tip handlers and the
trace leads all the way to ToolTipManagerImpl.reset() method.
Thanks Regards

Thanks Alex. Since the destroyToolTip is public and the doc says not to
call it on the currentToolTip, I'd probably think that it is used when we
explicitly create and destroy tooltips.
About faking the mouse event that you have mentioned, are you meaning that
I need to add my own tooltipmouseouthandler and put in my logic in this
handler?
Thanks

Subject: [flexcoders] NPE on ToolTipManagerImpl/reset()
Hi All
I am facing an NPE with tooltips, the problem is outlined below.
Set up: (I use Flex 2.0)
I have a UI where I have a datagrid that gets populated by data coming
from
a remote server call. My module contains a timer that sends out a refresh
request (server call) to paint the datagrid with the latest data. This
timer
fires every 20 seconds. Also, when I point to a datagrid cell, I see the
tooltip that shows the content of this cell.
This is what I have done to disable and enable tooltips during the server
call.
a) Prior to makign the server call, I destroy the current tooltip using
ToolTipManager.destroyToolTip(). I also set the
ToolTipManager.currentToolTip to null. I also make ToolTipManager.enabled
as
false.
b) On getting a response from the server, I set ToolTipManager.enabled as
true.
Now, here's the problem.
I keep my mouse on a cell and a tooltip is displayed. At some time T, the
20
second timer fires that makes a server call. At this very same moment, I
move my mouse out of the cell, so the tooltip's mouseouthandler gets
called.
I get an exception in ToolTipManagerImpl/reset() method. From the trace,
it
shows an NPE. This happens only when I move the mouse out of a tooltip
and a
refresh call to the server goes.
The lines around getSystemManager(previousTarget) is where I think I hit
an
exception, probably because the system manager for the previousTarget is
null and the next line throws an NPE, although I am not a 100% sure.
From ToolTipManagerImpl.reset() method
private function reset():void
{
if (currentToolTip)
{
// Remove it.
var sm:ISystemManager = getSystemManager(previousTarget);
sm.toolTipChildren.removeChild(DisplayObject(currentToolTip));
currentToolTip = null;
}
}
Any pointers to overcome this would really help.
Thanks
Ram

[flexcoders] Writing a Cairngorm ServiceLocator for 'fallback' services
Hi, I'm a Flash developer migrating to Flex and Cairngorm. I want to have my Cairngorm ServiceLocator use AMF Remoting as the first option but then fall back to a SOAP webservice if that fails. Both services have the same methods/operations as they are implemented in ASP.Net with WebOrb. I can define both the Remoting service and the webservice in the Services.mxml file in the usual way and can access both from my delegates and it all works fine. Here's my problem: The Cairngorm examples I have seen all show that the generic getService() method is depreciated and I should use getRemoteObject() or getWebService() from IServiceLocator. Using that approach I could put the logic to decide which service to use into each and every delegate but it would make more sense to have it centralised in the Services.mxml file and have this serve up the currently used service to my delegate. Since they both inherit the same methods, I should be able to call a generic services object using polymorphism and do some good OOP in the process. So here's my question: How would you experienced Cairngorm users out there approach this? - Should I write a new method in my Services.mxml component, which switches between services by binding it to a variable indicating which service type to use in the ModelLocator? - Should I scrap the mxml version and extend ServiceLocator in Actionscript? - Should I abandon this bit of the Cairngorm framework swc interfaces and write this from scratch? - Any other suggestions/warnings? Has anyone done something like this before? Thanks in anticipation of your help!
[flexcoders] Re: Saving data permanently to Sqlite DB

Thanx for your help.

Just a thought, I've not really checked your code in any detail at all.
If you're using a db file path relative to the application and you
left the compiler settings as is then this may well be the case.
It's worth noting that some OS's (e.g Vista) won't allow you to
change files in the application directory in any case, so you should
be copying the db to the users application storage directory if
you're to avoid problems with a published app.

Subject: [flexcoders] Saving data permanently to Sqlite DB
Hi,
I am having alot of trouble saving data to an Sqlite db. I have no
trouble, loading data, however commiting changes permanently seems to
fail.
I am using a delegate for the table. The code to execute any
sqlStatement is:
private function executeSQL(sqlStatement:SQLStatement):void{
if(sqlStatement != null){
sqlStatement.addEventListener(SQLEvent.RESULT, responder.result);
sqlStatement.addEventListener(SQLErrorEvent.ERROR,
responder.fault);
sqlStatement.sqlConnection = storyHelperConn;
sqlStatement.execute();
}
}
public function UpdateStory(story:StoryVO):void{
try{
if(!isDBOpen){
openDatabase();
var sqlQuery:String = update stories set title =
:titleText, +
where id = :id;
sqlStatement = new SQLStatement();
sqlStatement.text = sqlQuery;
sqlStatement.parameters[:titleText] = story.title;
sqlStatement.parameters[:id] = story.id;
sqlStatement.itemClass = StoryVO;
executeSQL(sqlStatement);
}catch(e:Error){
trace(Story Delegate Update Story error: +e.message + +
e.toString());
}
}
The database is stored in src/assets. I get no errors. When debuging i
can view the parameters, and they contain all the correct data.
Ive been pouring over various help sites and tutorials without success.
Can anyone suggest anything to look for? Possible uncaught errors, etc?
Regards,
Beriah

[flexcoders] Im new, and this is an old question
I am new to flex and RIA in general. I have been working with .net and java for a while now, and I am just starting to try to create a new interface for some projects of mine, and thought flex might be the answer, but I am having trouble wrapping my head around the idea that its less like a web page, and more like a desktop application, to stop thinking about page reloads, and start thinking about ViewStacks. So my original thought was to begin with multiple swf applications, and convert parts of the site over one part at a time (for instance, user registration, and then move on to the shared calendar, or another part of the site). But after doing some reading, it seems that its better to build the whole site as one application. Well I hope i can get some help, here is my question.. -- I did a lot of searching, and found a lot of posts that seem to disagree. The basic question is: I am building a big application for a website, using flex/swf as a front end, and .net as a back end. How do I control the project so that its not one monster swf file? Answers seem to range between using a single ViewStack, to using modules that you load in. Almost everyone wrote, to not build multiple swf/flex projects and try to communicate between them using .net or directly between swf files. -- I hope that is clear enough, so i should begin by learning about loading and unloading modules? Is that right? Thanks, Mike

[flexcoders] data grid columns adjustment
Hi, I'm working on datagrid columns adjustment based on the content of cells. Basically columns widths are adjusted based on maximum cell width in the column. I extended the DataGrid class and added adjustment on setting of dataprovider. The problem is that columns are not adjusted if the datagrid is not visible at the time of setting the dataprovider. For example I have a datagrid in an accordion component and if the data grid is not in the active panel at the beginning, the columns are not adjusted. After the data grid is shown for the first time, each later adjustment works, even if the data grid is not visible (i.e, not in the active panel of the accordion). I also want to invoke adjustment on data grid width changes. Does anybody has any ideas which events I can listen to for these two cases? The important thing is also not to invoke the adjustment too often, I mean not to attach it to an event which is often dispatched. Thanks, Grzegorz and Karl.

RE: [flexcoders] n00b question :)
It's essentially/simply used for your folder structure and then used to import in your various classes. So inside your src folder if you had a folder structure of src-com-mywebname - view, then any classes inside the folder 'view' would have a package name of com.mywebname.view and the import would be com.mywebname.view.*; or com.mywebname.view.myClassName; If your using flexbuilder it names the package for you. If you create a new AS file inside a particular folder flexbuilder will give the package name the same folder location. Should you move an AS file from one folder to another you will need to rename the package.

[flexcoders] Re: Im new, and this is an old question
Mike I don't know that I would agree with that idea. In my case I have had to build smaller applications because each part of our intranet is owned by different departments and they all want separate control over Their piece. Now that I have it up and running, I don't know that I would now make it into modules. All works well as it is. If a user clicks a link that goes to a different department, a new swf loads for that department. If I had a modular system, a new swf would load so what's the difference? I think in your case that you would be better off porting part of the site at a time. If you want to go to modules later on then you can do so. Think about how you would have multiple pages on the same page. eg. We have multiple table based pages that are built using PHP. With Flex we now have one page that loads multiple windows into that data.

package refers to the directory that the class is in. If the class file is in the root (src) directory, then there is no package name.

[flexcoders] Do states and transitions behave differently depending on the context?
I have a component which can appear initially in one of two states, and
can subsequently be switched between them. When this switch takes place,
I want a transition to occur. Here's a tiny model of my component:
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;
mx:states
mx:State name=state1
mx:AddChild
mx:HBox
mx:Text id=text1 text=t1:/
mx:Text id=text2 text=t2:/
/mx:HBox
/mx:AddChild
/mx:State
/mx:states
mx:transitions
mx:Transition
mx:Move targets={[text1, text2]}/
/mx:Transition
/mx:transitions
/mx:Canvas
If I embed this component (call it MyComp) like this:
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
view:MyComp currentState=state1/
/mx:Application
the transition takes place as the component appears, and everything is
fine. But if I put it inside a FormItem, like this:
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Form
mx:FormItem label=Type
view:SectionTypeControl currentState=taskQueue/
/mx:FormItem
/mx:Form
/mx:Application
the transition never takes place and the two labels remain superimposed.
In fact the problem is a little worse than this. In the toy
application above, you can replace FormItem by a container like HBox
and it works again. But in my real app I can't use it inside a Form
at all. What gives?

[flexcoders] Passing data to a cell on a DataGrid, and putting there a ComboBox
Hi, My application has an AdvancedDataGrid that shows a list of data. I would like that the user could edit data on the DataGrid itself just by clicking on a row/cell. After the click, that cell shows a ComboBox filled with data that comes from other data source different from the datasource provided to the AdvancedDataGrid. My problems are: 1- Best practices to pass the data (that comes from other datasource) to the ComboBox on the cell ? Should I extend the ADG ? 2- To show the ComboBox on the cell, the proposed solution is to use an itemRenderer or an itemEditor? What's the difference between both, and which one of them fits better on my problem ? 3- After the user chooses the value, I need to save the change somewhere. I am thinking on dispatching an event, with bubbles = true, and catching it on the AdvancedDataGrid parent. Do you think this is a good approach? Thanks, João Saleiro

resizing the image placing in a temp directory passing back the binary

RE: [flexcoders] Passing data to a cell on a DataGrid, and putting there a ComboBox
One set of answers: 1- Assuming the ComboBox dataProvider is the same for all rows, you couild bind it to a data model on the main application. 2- If I recall correctly, using an itemEditor and editable column makes flex display the editor when you click in a cell. You would use the normal DataGrid editing events to manipulate the data if needed. If set up correctly, the DG will handle updating the dataProvider. I tend to prefer non-editable columns containing full interactive itemRenderers that handle all of the display, and updating of the dataProvider item themselves. The itemRenderer has a reference to the current dataProvider row item. You can simply update the item there. Use the dataProvider API to update the item, to ensure the UI responds to the change. 3 - see 2 above Additional notes: * itemRenderers should be be data driven. You must update a renderers visual state based on changes to the underlying data. * If you want ComboBox to display the current cell value as the selectedItem, you will need to do some workl. * Interactive Item renderers are not simple, especially if youwant to perserve performance. Find an example and modify it. Do not start from scratch.

I would like that the user could edit data on the DataGrid itself just by clicking on a row/cell. After the click, that cell shows a ComboBox filled with data that comes from other data source different from the datasource provided to the AdvancedDataGrid. My problems are: 1- Best practices to pass the data (that comes from other datasource) to the ComboBox on the cell ? Should I extend the ADG ? 2- To show the ComboBox on the cell, the proposed solution is to use an itemRenderer or an itemEditor? What's the difference between both, and which one of them fits better on my problem ? 3- After the user chooses the value, I need to save the change somewhere.

RE: [flexcoders] TileList / DataGrid View Swap
If the mx:Canvas component you posted is to be an item renderer, then
you have some work to do. Item renderers myst be data driven. You
cannot use the initialize or creationComplete events for any row-level
work, because renderer instances are re-cycled. Thus there is no useful
meaning in the number of itemRenderer instances, and tracing the number
of times init() is called will tell you nothing of value.
I advise you find an example of an itemRenderer and modify it as needed.
That or study the docs. Both, probably.
You can display an image file stored on a server, with just the url.
Example, http://www.myServer.com/myImages/abc.gif. You would need a
crosdomain.xml policy file on the image server if the domain is
different than the domain serving the application.

In the ovveriden set data you can do any initialization you need as it is

remove it.

Well, actually it is at the operation/method level. The default is
object, which converts your soap xml into a tree of dynamic objects, and
this has some issues.
Change it to e4x, which will preserve the xml, to see if the behavior
changes.

RE: [flexcoders] Re: Populating a Flex Container in Flash
So you have a browser hosting the Flash Player, running a Flex app that contains a SWFLoader that loads a Flash SWF. In that Flash SWF, you implemented a UIComponent and inside of that you want to display a Flex application that you are going to build dynamically. Is that correct? If so, why so convoluted? Is the Flex framework available from within the Flash SWF? Also, UIComponent is not a container and will not do any automatic sizing or layout of the content. You will have to do that yourself. That means implementing the lifecycle, layout and measurement functionality. Say again why you want to do this? I'm not saying it is bad, just trying to be sure you have a god reason.

RE: [flexcoders] Re: WebService returning results, but event.result is null
Not specifically. But the default object conversion is the source of
*many* problems. It is a quick way to display data, but that is about
all. I don't see how, even theoretically, that a single algorithm could
handle any arbitrary XML input and produce a reliable, predicatable
object tree. And dynamic objects can have poor access performance, and
the object tree does not provide e4x expressions for manipulation. Ease
of use is its only benefit.
I steer folks away from it any chance I get.

Interestingly enough, setting the resultFormat to e4x does indeed
properly populate the event.result. I'm guessing this has got to be
some sort of parsing error in the WebService classes attempts to marshal
the results as objects. Has anyone else run across this issue?

Well, actually it is at the operation/method level. The default is
object, which converts your soap xml into a tree of dynamic objects,
and this has some issues.
Change it to e4x, which will preserve the xml, to see if the behavior
changes.

In the case of gutterLeft, the increased gap is on the left of the axis title, which looks a little odd, unless I can compute it based on the size of the numbers on the axis, or at least as a percentage of the container size. It might be more fruitful to do a custom renderer to display 20 as 200K. But thanks for the tips.

About faking the mouse event that you have mentioned, are you meaning that
I need to add my own tooltipmouseouthandler and put in my logic in this

Subject: [flexcoders] NPE on ToolTipManagerImpl/reset()
Hi All
I am facing an NPE with tooltips, the problem is outlined below.
Set up: (I use Flex 2.0)
I have a UI where I have a datagrid that gets populated by data coming
from
a remote server call. My module contains a timer that sends out a refresh
request (server call) to paint the datagrid with the latest data. This
timer
fires every 20 seconds. Also, when I point to a datagrid cell, I see the
tooltip that shows the content of this cell.
This is what I have done to disable and enable tooltips during the server
call.
a) Prior to makign the server call, I destroy the current tooltip using
ToolTipManager.destroyToolTip(). I also set the
ToolTipManager.currentToolTip to null. I also make ToolTipManager.enabled
as
false.
b) On getting a response from the server, I set ToolTipManager.enabled as
true.
Now, here's the problem.
I keep my mouse on a cell and a tooltip is displayed. At some time T, the
20
second timer fires that makes a server call. At this very same moment, I
move my mouse out of the cell, so the tooltip's mouseouthandler gets
called.
I get an exception in ToolTipManagerImpl/reset() method. From the trace,
it
shows an NPE. This happens only when I move the mouse out of a tooltip
and a
refresh call to the server goes.
The lines around getSystemManager(previousTarget) is where I think I hit
an
exception, probably because the system manager for the previousTarget is
null and the next line throws an NPE, although I am not a 100% sure.
From ToolTipManagerImpl.reset() method
private function reset():void
{
if (currentToolTip)
{
// Remove it.
var sm:ISystemManager = getSystemManager(previousTarget);
sm.toolTipChildren.removeChild(DisplayObject(currentToolTip));
currentToolTip = null;
}
}
Any pointers to overcome this would really help.
Thanks
Ram

Hi Alex,
I can move simple leafs from the root under a folder with no custom handlers,
if the folder is open. However the thing is that I need to just put (maybe just
copy not move) the item let's say for argument sake node label=Sent/
under Inbox folder. I cannot do that unless the sent is under some folder
and move it with the folder, because otherwise the DragSource seeems to return
an item but I cannot get the data from that item. So I end up dropping an empty
item. However as said before If I move/copy a folder with items around it works
fine ... The same happends with the drag complete handler, for just one item
the drags source traces out to blank event though the length is 1.

Setting breakpoints in drag/drop generally doesn’t work because you tend to
release the mouse in order to dig through the debugging info and when you
resume the drag is cancelled.
Remove the custom drag event handlers and try with simple data and see if it
works. We definitely tested drag/drop in Tree so basic cases work. One trick
for Tree is that what happens on drop is different than in List. The node is
removed before it is added in Tree, and sometimes that is done in dragComplete
handler instead of dragDropHandler

[flexcoders] one renderer forcing update of another

[flexcoders] Re: Flex drop down horizontal menu
Thanks for the tip. Can this be used to display a menu for website navigation? I guess I'd need a NavigateToUrl tag to allow menu item links to navigate the xhtml web page. In other words, I'm wanting the Flex application to only be for the menu not a part of a complete site done in Flex. Can this be done? Also, will the Flex application need to have the height equivalent to the highest opened menu? Or is there a way to have the Flex application - the menu - hover over the content on the xhtml web page transparently?

Re: [flexcoders] Drag And Drop Tree
It can be moved around but cannot be dropped into a folder (branch) unless the
folder is open. I was adding those handlers, so that i can drop item/items
inside a closed node... And it works for branches but not for leaf nodes ...
Setting breakpoints in drag/drop
generally doesn’t work because you tend to release the mouse in order to dig
through the debugging info and when you resume the drag is cancelled.
The funny thing is that the accurate data seems to be there at a certain time
when debugged, and i tried to store it in a private member of the component and
that works fine for branches, it seems that it just looses the data it probably
when dragging over a branch or I don''t know, but the length is still one so I
end up in adding an empty leaf. That also happens for the dragComplete handler.
Still adding an empty leaf...

because items is an array. Use XML.toXMLString( ) to make sure
you’re trying to put in valid data.

Hi
Alex,
I can move simple leafs from the root under a folder with no custom handlers,
if the folder is open. However the thing is that I need to just put (maybe just
copy not move) the item let's say for argument sake node
label=Sent/ under Inbox folder. I
cannot do that unless the sent is under some folder and move
it with the folder, because otherwise the DragSource seeems to return an item
but I cannot get the data from that item. So I end up dropping an empty item.
However as said before If I move/copy a folder with items around it works fine
... The same happends with the drag complete handler, for just one item the
drags source traces out to blank event though the length is 1.

Remove the custom drag event handlers
and try with simple data and see if it works. We definitely tested
drag/drop in Tree so basic cases work. One trick for Tree is that what
happens on drop is different than in List. The node is removed before it
is added in Tree, and sometimes that is done in dragComplete handler instead of
dragDropHandler

[flexcoders] Application language files
Hi guys, I want to store all my messages in a language class, common things like login fail messages etc, so I can easily change them later or perhaps add another language. I was talking with a friend about how best to do this, and we couldn't decide. At first we thought of making a LanguageManager singleton class with each translation as a const, but then we'd be bloating the application with unwanted languages. Maybe we could import a SWC at runtime with the correct language class?

RE: [flexcoders] LCDS - adding a new Item using createItem()
As long as your assembler's createItem method populates identity property of the item passed in, it should be returned to the client and updated there when the commit response is received by the client. To help diagnose why this is not happening, first upgrade to 2.6.1 (on the product download page) since it has better diagnostics than the earlier versions. Secondly, enable the server's debug log target for Service.*.In the logs, should see it calling your createItem method and what value gets returned for the identity property. If it all looks correct there, check the client mx:TraceTarget/ logs and make sure that value makes it back to the client. It should indicate in the client logs that it is updating the cache and that the id property is getting updated there.

RE: [flexcoders] one renderer forcing update of another
Yes. The core concept here is that itemRenderers must be data driven to work correctly. If your first renderer updates the dataProvider item, then the second one, which should be driven by the dataProvider, will update automatically. Remember, all itemRenderers have access to the entire row's data, via the data property. How advanced are your itemRenderer skills? Do you understand about the set data() override, the call to invalidateProperties(), commitProperties(), createChildren() and updateDisplayList() methods?

RE: [flexcoders] Re: Flex Builder 3 crashes (Vista)
On Vista, I would search for other copies of that file in weird places. A synchronization folder for example. I have no experience running FlexBuilder(FB) on Vista as I prefer to avoid painful challenges where I can. Here is an idea for you (although a little off topic). We don't install the full FB IDE but rather do the follow.. It also makes FB a lot faster and reduces the memory overhead.. This may seem really strange. All of our developers install the C++ version of Eclipse 3.3.2 and then disable the C++ plug-in. Then install the FB plug-in. There is just so much goo that comes in with standard FB from Java and JDT that when you will be surprised how quickly it boots. Downside is that those who do both Java and FB end up with two installs but we try to isolate Flex developers from IDE pain so I don't let them install many plug-ins anyway. The way the MXML preview component leaks memory, you have to take whatever shortcuts you can.

Oh. My bad - should read the entire thread first before posting.
I had a similar need, and ended up doing it in a loop like you did,

Does result = (uint(number) uint(comparison)) work?

[flexcoders] internationalization
I'm working on a project that requires multiple languages. I'm thinking I have two choices... 1) Use an XML file to change the text to different languages 2) Create a query/remote object through coldfusion to pull the different language. Are those my only options? Or should I say, what is the best way to do this? Has anyone done this or come across any articles? The articles I've found thus far deal with changing the currency/calendar/etc.. While that is something that I need to use, it's not the whole story... Thanks much. Scott

[flexcoders] Re: float-safe bitwise AND comparison
Thanks Josh.
I kinda managed to get it working.
so for the records if someone else need it, it seems to work fine.
private function
safeBitCheck(num:Number,comparison:Number):Boolean
{
if(num 2147483647 ) {
return (num comparison)==comparison;
} else {
var binNumber:String = strrev(base_convert(num,10,2));
var binComparison:String =
strrev(base_convert(comparison,10,2));
for(var i:uint=0; ibinComparison.length; i++ ) {
if( binNumber.length i ||
(binComparison.charAt(i)===1
binNumber.charAt(i)===0) ) {
return false;
}
}
return true;
}
}
public function strrev(str:String):String {
return str.split().reverse().join();
}
public function base_convert(num:Number, frombase:Number,
tobase:Number):String {
return parseInt(num+'', frombase+0).toString(tobase+0);

Re: [flexcoders] Re: float-safe bitwise AND comparison
This method is 10x faster, and more accurate (although the word is
meaningless at such scale due to the nature of IEEE floats):
private function safeBitCheck2(l : Number, r : Number) : Boolean
{
if (r l)
return false;
if (r == l)
return true;
if ((l = uint.MAX_VALUE) (r = uint.MAX_VALUE))
return (l r) == r;
var rs : String = r.toString(32);
var ls : String = l.toString(32).substring(-rs.length);
var split : uint = uint(rs.length) 1;
if (safeBitCheck2(parseInt(ls.substr(0, split), 32),
parseInt(rs.substr(0, split), 32)))
return safeBitCheck2(parseInt(ls.substr(split), 32),
parseInt(rs.substr(split), 32));
return false;
}
What on earth do you actually need this function for?

Re: [flexcoders] Re: Flex drop down horizontal menu
Yes you can use it as a menu for a website. A pure flash menu would be perhaps lighter, but I don't know by how much. For the navigation you have to use flash.net.navigateToURL(). The Flax app must have the height of the highest opened menu otherwise it will be truncated. But you can make the background of the app transparent (set the alphas to 0) and put it in a div on the top of the html page. For the div, use absolute positioning and give it the highest z-index. Use javascript to embed the app, use 'transparent' for the 'wmode' parameter and give a html-only replacement for the menu (even if it's a simple list).

Can this be used to display a menu for website navigation? I guess I'd need a NavigateToUrl tag to allow menu item links to navigate the xhtml web page. In other words, I'm wanting the Flex application to only be for the menu not a part of a complete site done in Flex. Can this be done? Also, will the Flex application need to have the height equivalent to the highest opened menu? Or is there a way to have the Flex application - the menu - hover over the content on the xhtml web page transparently?
