[flexcoders] Re: open new browser in maximized state
If all your users are running very old versions of Internet Explorer then you can use the ExternalInterface API to call a JavaScript function which calls the Browser/DOM window.open() function. The third argument to window.open() should have fullscreen in the features list (i.e., ..., fullscreen=yes,channelmode=yes, ...). This technique -may- even work on recent versions of IE, but I wouldn't rely on it work robustly (x-browser, or even x-version).

Our current web app is legacy ASP (not ASP.Net) and I have completed a prototype for SilverLight and as a C# developer I was able to get it done pretty fast. I was reading about Flex and it seems to be also straight forward. I have few questions if someone can help me with. 1. Is it possible to add a flex object to an existing ASP page. If not, how can I call and pass information between classic ASP and Flex, is it possible? As mentioned by the other respondent, ultimately a Flex application compiles down to a Flash byte code (.SWF) file. Your ASP page needs have a reference to that file, but via Object Embed tags. However, Adobe has already done a lot of the tedious work for you. When you build a Flex application, the IDE will spit out an HTML page with the proper tags and file reference already in it. All you have to do is serve that page up via ASP. As for data access, your Flex application can send data to your ASP server using the HTTP GET and POST verbs. When the server replies, it can send POX (plain old XML) in response. If you want to get fancy, you can also use SOAP, instead (but there may be some wrinkles doing that with a .NET/Windows stack). 2. I would like to know how to create a hierarchal data grid in Flex? I saw some examples of the new Hierarchical collection, if it is the solution, is there a simple example somewhere I can use? Try Adobe's documentation: http://livedocs.adobe.com/flex/3/html/help.html?content=advdatagrid_07.html 3. I would like to print reports from web and currently silverlight has buggy implementation of print, is it possible to print from Flex web page?

[flexcoders] Re: sizing dinamically the screen
Gustavo:
Sorry, but I don't think the approach you are taking is necessarily
advisable, or even technically correct (in one regard). Specifically:
1) screen.width (and screen.height, and screen.availableWidth, etc.)
allow JavaScript (DOM) code to discover the size of the user's monitor
(screen hardware), not of the browser window in which your Flex
application is running. (The available* properties then subtract from
that size any operating system 'reserved' screen real estate, such as
the Windows task bar.)
2) I would be very surprised if JavaScript code could alter the value
of any of these properties--by definition they could not be under the
control of a browser window, so they should be read-only. Therefore,
code like
screen.width = 1024;
should not be expected to work.
Even if that code _does_ happen to work with one Browser or Operating
System, I wouldn't rely on it!
3) A reasonably reliable way to ensure that your application is
running in a browser window of the size that you want, is to use the
JavaScript/browser DOM Window.open() method to open a new window,
which gives you the opportunity to specify the size of browser window
that you want your application to have. Be sure to note that you are
specifying the overall (e.g., outer) size of the window; you are NOT
specifying how much (client) area that your application will get. ***
Different brands (and versions) of browsers will use different amounts
of space for their own 'chrome' (UI elements such as the URL/address
bar, etc.). I don't know of any way other than cross-browser testing
to discover the exact values, and they may change when a new version
of a browser is released!
4) If you don't want to open a new browser window, then you can use
the Window.resizeTo() DOM call in order to modify the size of the
current window.
For both 3) and 4), security policy in modern browsers may affect: the
success of opening a new window (i.e., pop-up blockers), and to place
limits on net window size.
5) You can call the JavaScript/DOM code from your Flex application
using the Flash ExternalInterface API. For more information, see (for
example):
http://livedocs.adobe.com/flex/3/html/help.html?content=passingarguments_4.html
6) For more information about the Window.resizeTo() browser DOM API,
see (for example):
http://msdn.microsoft.com/en-us/library/ms536723(VS.85).aspx
7) My _recommendation_ is that you consider abandoning the notion of a
fixed-size application window. Flex containers support liquid layout
very nicely and it is not much (extra) work to let your application
work that way. In other words, if/when the user resizes their browser
window, have your application adjust its layout accordingly. If you do
that, I think that it is also reasonable to specify a (window) size
below which your application won't be able to re-size itself to (and,
thus, scroll bars may appear).
Good luck!

[flexcoders] Re: sizing dinamically the screen
Gustavo:
Sorry, but I don't think you're coding this correctly. Specifically:
1) I don't see your browser size detection code in the HTML wrapper
file at all. E.g., it is missing:
script type=javascript
var browserHeight= screen.availHeight;
var browserWidth = screen.availWidth;
/script
2) In any case, I'm not 100% clear as to what you are trying to
accomplish via the external interface. However, to get the available
screen width the following code will *probably* work (I haven't tried
it or tested it):
In ActionScript (note the quotation marks):
var width:Number = ExternalInterface.call(getAvailWidth);
assuming you have a JS function (in the HTML wrapper file) like this:
function getAvailWidth()
{
return screen.availWidth;
}
Then write similar code for the height, etc.
3) BTW, as a general rule, I've found it most productive to debug JS
code first (in isolation), _before_ attempting to call it from Flex.
4) Please look at the Adobe documentation for the ExternalInterface
API and the HTMLWrapper file again. I think--for now--you've reached
the limit as to what can reasonably be addressed via postings on
FlexCoders.
Good luck,

[flexcoders] Re: HTML and Flex
OK, I'll bite . . . The only solution that I can think of, off the top of my head, is to pop up a new browser window and embed just the TinyMCE instance in that window. When the user has committed their changes in the editor window, use JavaScript and Flex's ExternalInterface API to get the edited content back into the Flex world. And you need some code to close the pop up window, etc. Personally, I'd try real hard to work around that scrolling issue you mentioned, first, before I implemented the pop-up. --Jim --- In flexcoders@yahoogroups.com, bffoley bffo...@... wrote: I have a client who I am making a full-page Flex application for.

The issue here is the client uses TinyMCE in some homemade CMS to make updates to the rest of the content on the page, and he doesn't want to give this up. I haven't been able to find a solution that lets us import the HTML he creates in TinyMCE into the Flex app. I've seen a few iframe options that wont work because of the scrollbars (the iframe stays in the same spot, no matter where you scroll up and down on the page), and some other option I found that converts HTML to a Flash-friendly format doesnt support tables (only DIV tags), which TinyMCE relies on heavily.

[flexcoders] Re: Overriding margins using FlexPrintJob
Jeff: We're a little confused as to what problem you're really trying to solve here . . . I just tried the printing wizard (in XP's Windows Picture and Fax Viewer) application--I assume that's what you're referring to. When I tried the 'Wallet Prints' option, it scaled and rotated the image. It did NOT appear to affect the borders. And the image printed _with_ a border. Perhaps more to the point, AFAIK, the ability to print content *without a border* is a function of the brand/model of printer that one is printing to; it cannot be 'forced' by the software if the (printer) hardware doesn't support it. Unfortunately, however, it doesn't appear that Flex/Flash can programmatically specify that option. (Assuming that a user _does_ have a printer which supports border-less printing.) The Adobe documentation says: Flash Player and AIR can read an operating system's printing settings, but note that these properties are read-only: although you can respond to their values, you can't set them. So, for example, you can find out the printer's page size setting and adjust your content to fit the size. You can also determine a printer's margin settings and page orientation. I don't know if above is true from personal experience, however, so maybe some flexcoders readers who have done this would like to chime in here . . . --Jim --- In flexcoders@yahoogroups.com, Jeff Hindman jake...@... wrote: Flex AIR gurus, Is it possible to force printing to be borderless without setting it in the printer dialog box?

Your other choice is to have your entire application opened in a new, separate browser window, but with the browser 'chrome' history turned off.

[flexcoders] Re: Unformatting currency values - best practice?
It sounds like you're taking the 'high road' approach to this (i.e., letting users enter arbitrary currency strings and then trying to figure out the currency type after the fact and then checking the thousands separators and decimal point characters to see if they match that). That's a best practice usability-wise (at least if you agree with Alan Cooper...), but it can also take a lot of code to implement it robustly and it requires thorough testing. If you're willing to trade off some usability, you could have user's pick the currency type (i.e., USD, Euro, Yen), _separately_, say in a drop-down list; and then have them enter the actual value (in a separate text field). If you implement it that way, then your (currency) string parsing problem becomes much simpler. If you put the currency type selector _before_ the amount field (in the workflow/tab order), then you can also do things like dynamically changing the validator for the amount field, based on the selected currency. You could even have a 'no currency type selected' default for the currency type selector and disable the amount field until the user selected a particular currency. I don't know if I would consider the latter approaches as 'best practices' (especially from a usability perspective), but they are reasonable trade-offs. YMMV. I'm not quite clear on what you're trying to do formatting wise, however. Are you saying that you try to detect when a user has finished entering a currency amount, and then add currency symbols, thousands separator symbols, decimal point symbol, etc.? Regards, Jim --- In flexcoders@yahoogroups.com, flexcoder2008 [EMAIL PROTECTED] wrote: What is the best practice or a good recommendation for formatting currency values and then removing the currency formatting for saving to the database? Here's what I have attempted to do so far. It works - but only if the user enters plain old numbers - if they add any currency symbol or thousand separator, it fails. I have a form which has some textInput's that are formatted with currencyFormatters. I initialize each textInput's .data property to 0. The textInput displays formatted currency amounts from xml data retrieved from the database. On the focusIn event, the text property is assigned to the textInput's .data property, so the value stays the same but the formatting is gone. And when a change event fires, the unformatted text in the textInput gets updated to the data property as well. On the FocusOut event, the currency formatting is re-applied. When I save to the db, I use the textInput's .data property. So for the most part this works, but fails if the user enters any currency symbols. Is there a good class or function someone could recommend to take a currency value in a textInput and strip out all the extra formatting characters? I am also trying to implement localization, so the various currency symbols will be different depending on the locale. Thanks

[flexcoders] Re: Flex 3 - Export to Microsoft Excel?
I've successfully implemented two different approaches. The first approach just puts the data for Excel _on the clipboard_. It also uses Microsoft's uber-funky XML schemas to control the formatting of the resulting spread-sheet. This approach works nicely for both FF and IE, in my experience (and, in theory, it should work in any browser that supports the Flash VM, including clipboard access). The second approach uses the ExternalInterface API to call a JS function which uses ActiveX to invoke the Excel COM object. If the JS function is able to load the Excel object, it then calls the object's COM interface directly (via JS functions) in order to create a Workbook and then to load data into its cells. Unfortunately, this approach only works with IE, but it is slick if you can use it. But, having the first approach as a fall-back is a good idea even then, in my opinion. Let me know if you have any specific questions about implementing either of these. Regards, Jim
[flexcoders] Re: Creating a Chart With 50,000 Data Points
50,000? LOL. ;-) On a more serious note, I have to agree with Fotis and Ricky that 50K data points is too many, both from a (Flash 9 VM at least) performance perspective and probably also from an Information Visualization perspective (unless, maybe, your users have 300 dpi monitors). There are several standard interaction design and information visualization techniques which may be useful to you . . . 1) Aggregation (as already suggested, take 'N' data points, average them, and then only display the average value). 2) Filtering (by sliders on an axis, by date/time, by structured or open-ended queries, ...) 3) Progressive rendering (sample the entire data set at intervals of 'N', render those points, then go back and get the data which is mid-point between the original points, add the new points to the curve, repeat until desired resolution obtained--or on user demand) 4) Non-linear zooming (like idea 1), but allow user to zoom in on a section of the curve, when they do, add the additional data points to the curve for the zoomed-in region) On a more pragmatic note, you certainly _can_ plot more than 2,000 points. For example, I've personally used Flex to create charts with over 14,000 points in them, so I know that at least that number is definitely *possible*. However, the overall rendering time was (as I recall) over 3 minutes long. More troubling was the fact that the entire Flex UI become very sluggish once a chart that large was displayed. I've seen good chart rendering speed ( ~= 2S ) and no UI sluggishness, up to about 1500 points. I've also been able to render up to 6,000 points, but it took about 10S for the rendering and the UI started to become sluggish. From your posting, it sounds like you're not seeing those rendering speeds. I'd recommend that you experiment with how you are using the charting objects/API. My experience was that I was able to see some very noticeable speed-ups simply be optimizing how I called the charting API (especially w.r.t. how I loaded the series data). In particular, if your charts are interactive, try to cache anything you can that doesn't necessarily change during an interaction (i.e., axis objects). Last thought: the new Flash 10 VM (Astro) has support for larger bitmaps and also can now do hardware-based rendering, apparently. I haven't tried either of those features myself, but using the v10 VM _might_ be another way to get a performance boost, etc. Good luck!

[flexcoders] Re: Setting cursor to particular text box on the application load
In order for this to work, your application _as a whole_ needs to do
two things. One of them is (in Flex) to use the setFocus() method to
specify where (in the Flex applications) focus should go. From your
posting it appears that you have already done this.
The other thing is that the _entire Flex application itself_ needs to
first get focus. This is not done in Flex, it needs to be done in the
'HTML Wrapper' page which loads the Flex application. Please locate
your Flex project's index.template.html file and open it for
editing. Then add JavaScript code which will cause the Flex
application to receive focus when the HTML page is loaded. The
simplest way to do this is to add an inline event handler to the
page's BODY element. For example, if the HTML Wrapper page is being
viewed in the IE v7 Web browser, then the following code should work:
body scroll=no onLoad=window.document.${application}.focus();
Please note that the behavior might be slightly different in other
browsers (i.e., FireFox, Safari, etc.) and you may have to tweak the
JavaScript code to achieve a robust solution.

Jim

In the event handler, I use the id of the event's target to decode which control the user is tabbing _from_ and then set nextTabItem and previousTabItem properties based on the currently focused control plus the target control's enablement state. Then I call setFocus() on either nextTabItem or previousTabItem, depending on the keyboard Shift state. Lastly, I call this.focusManger.showFocus(), because it seemed that the current focus highlight was not always being rendered if I didn't call the showFocus() method.

My specific questions are: 1) If the overall container (i.e., the TileList) instantiates or shows an ItemRenderer, then how do I get the keyboard focus set to a particular control in that new ItemRenderer/control container? FYI: I've tried adding code to the ItemRenderer's CreationComplete and Show events that calls the target control's setFocus() method, but that doesn't work. I also tried it using the FocusManager's setFocus() method--also doesn't work. 2) How do I get the keyboard focus to move from control to control (in my ItemRenderer/control container)? FYI: I've actually gotten this to work (more-or-less), but it took so much code that it seems kludgy to me and I'm wondering if there is a better way to do this. What I did (the kludgy? way) was to add an event listener for the FocusEvent.KEY_FOCUS_CHANGE to the ItemRenderer/control container. In the event handler, I use the id of the event's target to decode which control the user is tabbing _from_ and then set nextTabItem and previousTabItem properties based on the currently focused control plus the target control's enablement state. Then I call setFocus() on either nextTabItem or previousTabItem, depending on the keyboard Shift state. Lastly, I call this.focusManger.showFocus(), because it seemed that the current focus highlight was not always being rendered if I didn't call the showFocus() method. Note: the user is tabbing between TextInput, Button, and RadioButton controls--I need solutions that will support at least all of these controls, preferably all focus-able controls. Does anyone have a best practice (or at least better) way of doing this? Thanks in advance for you help--flexcoders is a great resource! --Jim

[flexcoders] Re: Base64Encoder / Base64Decoder
Has ANYONE got a code sample (of the Decoder, especially) they'd like to share? I'm using the Decoder right now and can't get it to work. Of course I don't know yet if its in my AS3 code; the server guy's Base-64 code (in Java); or--dare I say it--in the Flex library.
[flexcoders] Re: Flex Enhancement, TabIndex
Please VOTE for SDK-16016 (https://bugs.adobe.com/jira/browse/SDK-16016), in addition to SDK-16897 (https://bugs.adobe.com/jira/browse/SDK-16897), if you want tab key support to be fixed, including usage in item renderers.
