Check out Number.toString(). You can pass it a radix parameter of 16
to convert the output to hex.

selected is, 66, if I trace ColorPicker.selectedColor, traces
102. I

Cool. Here are a couple other ways to pad the 0's, for anyone with
an aversion to loops:
hexString = 00.substr(0, 6 - hexString.length) + hexString;
or:
var pads: Array = [00, 0, , 000, 00, 0, ];
hexString = pads[hexString.length] + hexString;

[flexcoders] Re: creating a World Clock and need a little help with the time and date
Bah. Obviously I'm not testing any of this myself - I'm leaving that up to you! A call to new Date(0).getTime() will just return 0, so that won't work. What you need is the number of milliseconds *between* 1 AD 00:00:00 UTC and Jan 1, 1970 00:00:00 UTC. I don't think there's a way to use ActionScript's Date class to determine this. You can use a different technology (Java's GregorianCalendar class, for example) or just extrapolate an approximation of that value. It will be a constant once determined. (1970-1 = 1969) yrs * 365.25 days/yr * 24 hrs/day * 3600 secs/hr * 1000 ms/sec * 1 timeticks/ms = 6213691440 timeticks (100ns) (This is definitely an approximation, since there aren't precisely 365.25 days per year, and it doesn't account for leap seconds, etc., but it might be close enough) Adjust CurrentTimeTicks by that constant and pass it to Date(), converting to milliseconds somewhere along the way: new Date( (CurrentTimeTicks - 6213691440) / 1 ) or: new Date( CurrentTimeTicks/1 - 6213691440 ) Hope that gets you a bit closer to a solution. --- In flexcoders@yahoogroups.com, Doug Lowder [EMAIL PROTECTED] wrote: Sorry, I missed a parameter in there - that should have been new Date (0). new Date( CurrentTimeTicks / 1 - new Date(0).getTime() ) If you truly have a 100ns count since 1 AD as CurrentTimeTicks (the math works out, but you should still verify that with the webservice if possible), then you would need to adjust for the difference between CurrentTimeTicks=0 (presumably Jan 1, 1 AD 00:00:00 UTC) and Date(0) (Jan 1, 1970 00:00:00 UTC) and pass that to Date() after converting to milliseconds along the way. --- In flexcoders@yahoogroups.com, Mark markp.shopping_id@ wrote: I tried a few things along those lines and not even getting close... really: setDate = new Date(nanoSeconds/1000 - new Date().getTime()); RETURNS Tue Jun 20 09:55:17 GMT-0400 1933 setDate = new Date(nanoSeconds/(60*1000) - new Date().getTime ()); RETURNS Tue Jun 30 09:26:26 GMT-0400 1931 setDate = new Date(nanoSeconds/(60*1000) - new Date (1970,0,1,0,0,0,0).getTime()); RETURNS Mon Jan 12 19:17:43 GMT- 0500 1970 setDate = new Date(nanoSeconds/1000 - new Date (1970,0,1,0,0,0,0).getTime()); RETURNS Mon Jan 3 19:43:04 GMT- 0500 1972 There's a problem with the math but I'm just not able to find it.

[flexcoders] Re: DateFormatter gives weird results
Hi Chris,
It seems like you are located in a GMT -0500 timezone, and what looks
like 19 hours being added to your time is actually 5 hours being
subtracted (24 - 5 = 19) so you end up seeing 19 hundred hours from
the previous day. This is because the Date() constructor with a
single argument expects a value in GMT, but Flex does automatic
conversion to client local time. Have a look at the
Date.getTimezoneOffset() method as a way to help convert to local
time.
HTH,
Doug

[flexcoders] Re: Securely Interfacing Between Flex and Databases
Kenny, are you saying you want to implement security *within* your Flex app? I think you'd have serious security holes with that (your decompilation concern, for one). Typically security would be handled at the client-server level, by hosting your SWF on a server that has been configured to accept connections over https (e.g., https://myserver.com/myapp), connecting to your app via HTTPS from a browser, and designing your Flex app to connect to other servers over HTTPS as well. Web servers and browsers already have built-in implementations of RSA, SSL/TLS, and the other industry standards mentioned in other posts so there's really no need to implement them yourself. The same SWF (with certain design considerations taken into account, of course) can be accessed on the web non-securely (over HTTP), or securely (over HTTPS). HTH, Doug --- In flexcoders@yahoogroups.com, kenny14390 [EMAIL PROTECTED] wrote: So the bottom line is to use an algorithm like RSA? To take a much simpler example, if the Flex app receives the encrypted data 1234 and it wishes to use that data, it must first decrypt it. So it performs the decryption in some AS and now you have the decrypted data that you wanted. My question now is, if someone decompiles your app they can see your decryption method and thus decode the data on their own. Nothing is private in the Flex app due to the decompilation concern. Regarding SSL, I suppose this is out of the question if we're talking about a Facebook application. I don't have much control over their security. --- In flexcoders@yahoogroups.com, andrewwestberg andrewwestberg@ wrote: I think you're confusing simple secret key encryption (DES, AES, etc..) with public/private key encryption (RSA).

A simple {status.selectedValue access.selectedValue} would be
desired, but it causes an error in Flex. I tried using || rather

[flexcoders] Re: unable to bind to property warnings binding to read-only properties
Binding has a lot of associated overhead and doesn't really serve any
purpose when it's a value you know is never going to change.
Somehting like the following works well for me.
someProperty={foo.bar}
becomes:
creationComplete={event.currentTarget.somePorperty=foo.bar}

if foo is an [Bindable] instance of Foo, then a binding to
{foo.bar}

warning: unable to bind to property 'bar' on class 'Foo' (class is

Foo is not an IEventDispatcher, but since every property of Foo is
immutable it shouldn't need to be.
this may be a flex defect, judging by the title of the defect at
http://bugs.adobe.com/jira/browse/SDK-1046. i've asked adobe
support

i'm interested in strategies to avoid this warning for read-only

me
figure out a binding problem, but unfortunately the important
warnings are nearly impossible to find among the hundreds of
irrelevant warnings for binding to read-only properties.
here are some of the strategies i can think of, none great (i'll
continue using the above Foo class as an example):
1) don't bind to {foo.bar}, bind to {getBar(foo)} or {foo.getBar
()},
adding the getBar method either to the MXML component trying to
bind
to foo or the Foo class itself.
2) declare the bar getter function as [Bindable] to a made up event
name, e.g.
[Bindable(event=barChangedNeverGonnaHappen)]
are there other strategies people have employed to eliminate these
warnings for read-only properties? i trust i'm not the only one
whose eclipse debug console has been consumed with warnings like
these.

You just have the wrong format string for your DateFormatter. HH

[flexcoders] Re: Return a person's age
Ah, but if the OP wants an answer in the form the person is X years old today, that's where the problem arises. A good edge case is: Birthday: 2/28/2000 Today: 2/27/2001 With the getTime() approach, new Date(2/27/2001).getTime() - new Date(2/28/2000).getTime() gives 3153600 (Jan 1, 1971 UTC), or 365 days. In this case the age is not 1 though, because that year was 366 days instead of 365. That's why I would still choose to do the calculation without getTime(), and why I don't think those doc examples are particularly good ones - a day is not always 24 hours, a year is not always 365 days, etc. And sorry for beating a dead horse so badly! :) --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: Oops, yes, the subtraction should be reversed. But one of the overloads of the Date constructor takes a single argument, the number of milliseconds from the reference date, the same reference date as the getTime() method.

Great work, this is really nice stuff! I've worked on a couple of these myself, so I know how many details there are getting something like this implemented. I have a few questions and comments: . How is the performance with windows filled with content (say, a tree, grid, and/or chart) as opposed to empty windows? I've run into serious performance issues with only a few windows, depending on the type and number of child controls, mostly due to the performance of using setStyle() on inherited properties like border color. . You have solved a problem I've seen in pretty much every resize manager I've come across so far: Releasing the mouse button while the cursor is outside the browser window during a resize. That problem seems to exist during window dragging though (i.e., start dragging a window, move the cursor outside the browser window and release the mouse button, then move the cursor back into the browser to start the strangeness). Maybe that's a bug in TitleWindow, if that's what your MDI window extends. . When a window is maximized, I see there are still drag events being broadcast, and I can even drag the maximized window up and down a few pixels. Not sure if you intended for that to happen. I admit that's getting nit-picky but I thought I'd mention it. Again, great stuff overall.

So here is what I'm seeing with a freshly-loaded app in IE7 on Windows XP Pro, FlashPlayer 9.0.47.0: I click and hold the mouse button on the titlebar of Window 2 to begin dragging. Moving the cursor to any browser-window edge (I moved it left), Window 2 follows and stops when it's aligned with the browser edge (nice touch, btw). So far so good. If I continue moving the mouse outside the browser window completely (Window 2 has stopped following the mouse as it's already as far as it is allowed to be dragged, no problem there) and then release the mouse button, Window 2 will begin tracking the mouse again when it returns to the browser, even though the mouse button has been released.

How is the performance with windows filled with content (say, a tree, grid, and/or chart) as opposed to empty windows?

This resulted in the entire TileList having a grey color over (or under) it, which is the default behavior for a disabled TileList. I found the backgroundDisabledColor and set it to #FF, which ALMOST solves the problem. The remaining issue is that the currently selected item in the TileList still has the grey background.

I have been working on a calendar of events flex application as most
anybody who monitors these flex lists probably has noticed. This is a
reworking of an existing [D]HTML/CFML application. Part of the current

I am trying to convey this same information in the flex version. I
have
tried using a strike-through decoration, but my attempts to use

The String class does that though, doesn't it? For example,

var sid2 :String = ID_101-102-103;
var sid3 :String = new String(sid1);

Hi,

There is no way you can do that. AS3 uses typing and that is all
you are
doing.
The is the string constructor and there is no way to change that.
If I understand what you are asking there is something you can use
so you
don't have to use toString().
public function StringId(stringId :Object)
{
if (stringid is StringId)
this.guid = stringId.toString();
else if(stringid is String)
this.guid = stringid;

var sid3 :StringId = new StringId(sid1);
Is there any copy constructor / assignment operator / multiple

The last one I can either replace with:
var sid3 :StringId = new StringId(sid1.toString());
or have the constructor make the distinction between the String

[flexcoders] Re: Open new browser popup
On the client side (Flex), take a look at URLLoader and URLRequest in the docs. URLRequest has a method property that you can set to POST to fit your needs. For the server side, here is an example in JSP (ignore the HTTPService portion) that is close to what you will need: http://tech.groups.yahoo.com/group/flexcoders/message/43818 And something similar for PHP: http://tech.groups.yahoo.com/group/flexcoders/message/16370 Take notice of the content-type and content-disposition header, and be sure to handle any exceptions that may occur. If your server-side page accepts GET as well as POST, you can easily test it by typing the URL into a browser; once that works it's just a matter of hooking it up to the URLLoader in your Flex app. One round-trip instead of two, a nice dialog with Open and Save options for the end-user, and as long as you can deal with the pdf as a stream instead of a pre- created file, no leftover temp files to clean up. --- In flexcoders@yahoogroups.com, Peter [EMAIL PROTECTED] wrote: Thanks for the reply. In my case, I have to POST a bit of data to a servlet which will generate the pdf. On the server side I can basically do whatever it takes, but it is unclear to me what that is and it is even less clear what I need to do on the client side. For now I use a HTTPService post. This generates the pdf in a temp directory and returns a handle to this pdf file to the client. In a second request, the client invokes (per the gentle help of the people in this thread) ExternalInterface.call(window.open, pdfUrl, _blank, ); That basically gives me what I want, except for the fact that I need to save the pdf to a temp file and that it requires 2 requests to the server.

Yes, that's it exactly and Adobe got it right. The + is listed as a non-encoded character in the docs for encodeURI().

(list, valid, id in this case) and values in order to allow the user
to change the values in a flex application.
Have anyone experienced the same issue? Any Idea?
Thanks for your help!
P.S.: Note that the JSON string is dynamic, so i need to evaluate
the
names of the variables at runtime.

[flexcoders] Re: timezone and dateformatter
That's correct though, isn't it? If I'm a user in CST and I access
your app on 4/30 at 9PM, I'd probably be wondering How could my LAST
billing date be 5/1, which isn't until tomorrow?
But if that's what you want, you can add the timezone offset to the
date being formatted. If item.lastBillingDate is Date object,
return df.format( new Date( item.lastBillingDate.getTime() +
item.lastBillingDate.getTimezoneOffset()*6 ) );
Your Java code should be returning a date in UTC. If it isn't,
you'll have to adjust for that offset as well.

[flexcoders] Re: timezone and dateformatter
Sounds like some of our legacy tables, where someone decided to store
dates as formatted varchar strings instead of something more
appropriate like Date or Timestamp. What a pain.
If you're forced to use the existing datetime column, I guess there
isn't much you can do. If not, maybe you could add a numeric column
and store the dates as milliseconds since epoch. That would make
retrieving ( new Date(valFromDb) ) and sending ( myDate.getTime() )
pseudo-date values easier.

wrote:
I've also ran accross this, not so much a bug though. It works
properly in
its use case. The problem is, there are other use cases with
timezones.
Here is my scenario:
I work with a legacy database. Unfortunately, all datetimes are
saved into
the database as UTC, but as the clients time zone.
So say someone in the EST -5 UTC and someone at PST -8 UTC both
saved at the
same moment in time (5am EST). The database would have saved the
dates as
following:
EST - 05:00
PST - 02:00
I can't change the behavior due to only being one piece in the
grand scheme
of the application. The problem is, the databse doesnt' know what
timezone
these are. The system was designed to just show that datetime to
the user
if they ask for it. Flash/Flex always converts AMF Dates to the
local
timezone. I've asked for a way to hook into that deserialization,
but I
haven't gotten a response.
Therefore, I massage every date I receive and every date I send
using the
following...
*
public* *static* *function* getUTCDate(myDate:Date):Date
{
*if* (myDate == *null*)
*return* *null*;
*else
*
*return* *new* Date(myDate.fullYearUTC, myDate.monthUTC,
myDate.dateUTC,
myDate.hoursUTC, myDate.minutesUTC, myDate.secondsUTC,
myDate.millisecondsUTC);
}
*public* *static* *function* sendUTCDate(myDate:Date):Date
{
*if* (myDate == *null*)
*return* *null*;
*else
*
{
*var* sDate:Date = *new* Date(Date.UTC(myDate.fullYear,
myDate.month,
myDate.date, myDate.hours, myDate.minutes, myDate.seconds,
myDate.milliseconds));
*return* sDate;
}
}
Hope this helps, but I hope even more there is a better solution out
there

if you want times always displayed based on a fixed timezone

coldfusion on
the back end, just Java.
In our case, we are able to code around this by using rationals
instead of
date fields, a soon to be used fix. We just need a start time

between 6am to 10pm and have a separate field with only the

Nate, sorry it is not quite that easy. You are passing a parameter

This will work if you call the .swf directly, with the querystring

To do this in a production environment (if the parameters are
dynamic)
you will need to have a server platform generate the html file.
The easiest way to do this is to look at the generated html file
that
FlexBuilder creates. In the javascript call, you will need to add
your
parameters to the flashvars line in AC_FL_RunContent(... like:
flashvars,'historyUrl=history.htm%3Flconid=' + lc_id

Of course you will have the server (asp, jsp...) output the actual

[flexcoders] Re: Changing a string to reference an ID of an Object
You can still create the instances dynamically, but you'll need a non-
local variable to store the *references* to the instances so you can
get at them later on in your WS handler. Maybe an Array would work?
You could push the dynamically-created RTE instance onto the Array
and then pass an array index integer in addition to a string
equivalent to the name of the array variable. You could then access
the RTE instance in your handler as:
var theArray: Array = this[_resultID];
var myDynamicRTE: RichTextEditor = RichTextEditor(theArray
[_resultIndex]);
Hopefully this is all making sense to you. There are probably other
(better?) approaches as well; possibly a custom event for you service.

[flexcoders] Re: Help with finding days between a start and end date
Your math is OK, but for timezones that support Daylight Savings Time
your logic isn't. In those timezones, not every day will be exactly
24 hours long. A quick way to verify is to make the following change:
hListArray.addItem(lastDate.toUTCString());
If you need dates converted to local time, you'll have to adjust for
the timezone offset of the date in question. I think the following
should work:
var lastDate:Date = new Date(nextDay);
lastDate.setTime(lastDate.getTime() - lastDate.getTimezoneOffset()
*6);
hListArray.addItem(lastDate.toLocaleString());
You may also have a few issues to sort out regarding the timezone of
the stored dates, and how those stored values are initially converted
