[flexcoders] Re: RIA: record insert best practices
I'm no expert in Flex and RIA development but i have implemented creating the ID on the client using the createUUID to generate a GUID which by all practible means it will be globally unique. I found this to work well, plus it saves me ALL the hassle of generating a temporary ID and then get the real ID back after i post the results to the server. I'm generating many updates and a lot of times i'm updating parent child relatinships so if I don't have the real ID ahead of time it would be a large amount of work to get the real parent id then go through all the children and update the reference key based on the temporary key assigned to it on the client... it's even hard to explain in a sentance or two. Some pureist will think it's crazy to generate the key on the client, and I partly agree. But if it works, it works. You can also setup a method to request a block of unique IDS on from the server if you don't want to create it on the client itself. This keeps your ID generation centrally controlled but you still have the benefits of knowing your IDs for particular updates before sending them to the server. Some of it also depends on the ID types in your database. I actually am now using GUIDs in a SQL Server database and not using identity increment values. Even though my primary key indexes are a bit more fragmented i have not found a performance loss, just a bit larger database since i'm storing a 16bit id value instead of a 4 bit integer value. In my case i'm trying to build rapid applications and i generally have oen app and one database so generating IDs on the client is ok in my circumstance... maybe not the best for all. --Scott --- In flexcoders@yahoogroups.com, arieljake [EMAIL PROTECTED] wrote: I am wondering how people like to handle insertion of records in a RIAs for records that have a unique number field. Do people determine the unique id on the client side and create the record, or do they do that server side and return the new ID number back to the client. I prefer to do the MAX(id) check on the server in the database within a transaction, but I am realizing that doing it that way sort of forces me to block user interaction in the RIA until the ID is returned lest the user try to do something with that new record that I cannot support yet. Thoughts? Thank you.
[flexcoders] Re: Html Text does NOT print in same format as rendered on scre
John,
I ended up going a different route.. i'll use this technique in the
future. It was a great expirement. The print quality just wasn't
good enough.
Anyway, I wrote a recursive routine to find all Text controls, then
manually reset their heights for printing. For reasons, unknown to
me, when you add a couple pixels to the height of Text object, then
print, ALL lines print.
Each time i found a Text control in my DisplayObject being added to
the printJob, i determined line count (oddly, no built in lineCount
property), went through each line and got the lineMetrics and
calculated a new height, plus added a few pixels to be sure. I did
all this between calling my printJob.start() and printJob.send().
Oh, setting my printJob.printAsBitmap to false is also very good for
quality and they suggest that in the docs if not printing images or
non-vector stuff... the print quality is crystal clear!
I agree this is a hack... but when there's LITTLE documentation and
it doesn't work as expected i was under the gun to get something out
since i released my app... before testing all printing scenarios...
--Scott
Turning off printAsBitmap on the print job seems to condense the text
a little so if you only have one word on the last line, it's possible
that it's brought up to the previous line. This may cause an extra
blank space when printed, minor issue, but all text prints, the most
important thing.
I went through several different fonts and sizes and now very rairly,
a letter gets clipped on the right, i'll figure this out later.

all (though still not great) was to set smoothing = true for the
Bitmap. It looks better but is now a little fuzzy and on paper
(cheap
inkjet) the text is not as dark as the one without smoothing. I'm
wondering if it's possible to overlay the no-smoothing bitmap with
a
transparent background over the smoothed version?

[flexcoders] Re: Shouldn't this VBox have a scrollbar?
You would think so... however, i have found that you have to set the
height of a vBox to a pixel height, not percentage to get the
scrollbars to act the way you want them to.
By default a vBox's height will autosize to the combined height, plus
verticalGap... of all it's children, UNLESS you set it's pixel
height, which then properly display's scrollbars.
In this case, I would bind the height of the vBox to it's parent
canvas height, that should do it.
This is very weird to me as well, and if you contrain the layout of
the vbox to be top=0 and bottom=0, as if you are wanting to anchor or
dock it so it resizes when the parent resizes, it won't work either.
The height must be set to a pixel height. To get around this i had
to tie into the resize even of my parent container and convert the
size of my vbox appropriately... annoying, not what i expected i
would have to do.
hope that helps some

[flexcoders] Re: Shouldn't this VBox have a scrollbar?
Oh, and one more thing, hopefully i don't butcher this.
As explain to me before, using constrained layout on objects does not
actually resize them, just anchors them based on teh top, bottom,
left and right properties. That's why you can't anchor a vBox on all
sides and expect the scrollbars to appear correctly.
Constrained layout is NOT equal to Docking as some other editors,
such as in Visual Studio refer to it.
This is wierd if you anchor on all 4 sides, put a border on your vbox
and it does appear to grow with the parent display object it's anchor
against, but again, the vbox size, at least for calculating
scrollbars is NOT aware of this. I assume this is very similar to
using 100% values for width and height.
Weird and certain not what i would expect.

[flexcoders] Any good documentation on printing text.....
Any really good articles on the fine points of printing text? Or am i just running into bugs out of my control I'm trying to print Text boxes with html text but never get consistent results. My text box looks like this: mx:Text id=myText width=450/ The height of myText grows, depending on how much html text i assign to it. It previews on screen just fine. I'm stacking 3-4 text boxes on top of each other in a VBox so I don't want to set their heights because i want them all to run right after each other. However, when printing them i always lose a line of text. I've tried embedding the fonts, setting my flex print job to printAsBitmap to true and false and never seem to get consistent print results. The text always gets rendered slightly different on the printout as well, slightly different spacing, sometimes causing text to wrap to a new line. I'm willing to pay for help... this is very frustrating and I could be running into issues out of my control or something so simple it's not funny. I just can't find great info on printing text.

[flexcoders] Re: FlexPrintJob not printing multiple formatted lines successfully
Geneva, Tahoma and Verdana are 3 problematic fonts i have isolated to not print correctly. I never get the last line of text to print. These 3 fonts are installed on my pc. The height of my text area is not set, it grows with the amount of html text and this has worked very well. Always showing all text on screen but these 3 fonts never want to print the last line. However, for these 3 fonts if I set the height of my text control to 2 pixels larger that what it would normally grow to when the height is not set, everything prints out ok... but I can't set the height of my text controls because I don't know ahead of time how much text they will contain.

Thanks for the reply... however, why would fonts display correctly on screen and size the text box correctly but not print the same way it was rendered on screen? Must be luck of the draw on other fonts, because they do not produce the same bahavior when printing. Embeding Verdana using [Embed(systemFont='Verdana', fontName='Verdana', mimeType='application/x-font')] Does fix the problem of the last line not printined correctly but then anywhere else in my app this embeded font shadows the system font and print outs are very poor quality and all other labels/buttons using Verdana are very fuzzy...

[flexcoders] Html Text does NOT print in same format as rendered on screen..
Text/Fonts render differently when sent to the printer than when viewed on screen, this is a real PAIN when formatting display objects to send to the printer. I've added a few Text controls to to a vbox with variable length data, some have custom font formatting, ALL installed fonts, even tested with embedded fonts. The width of the text box is 100%, which fills to the width of the vbox, and the height is not set, so it grows to show all text. Works great.. except when sent to the printer. When I send these text controls to the print job.addObject and set scale type to show all, the text breaks at different points and does NOT render the same as seen on screen. If the text happens to render a bit wider, teh font could go to the next line and therefore NOT print. I JUST WANT THE Text DISPLAY OBJECT to print on the printer in the exact format/rendering as seen on screen... is this not possible. I think when you send this text control to the printer, flash trys to get smart and not render the text as an image but as text... which changes some line breaks and such... this is really annoying. Not sure how to solf this issue... just want all my text to print. Any help would be appreciated. I posted this same issue in another post... not sure it was clear as to what my problem is.
[flexcoders] Re: FlexPrintJob not printing multiple formatted lines successf
Unfortunately i'm finding that out the hard way.. printing on and on screen display are different beasts... i ultimately just want my display objects i'm sending to the printer to print exactly as they appear on screen... I actually just posted antoher thread on this topic, wasn't sure i was clear in the first. When i embedded the Verdana font, all button labels and text labels that used the Verdana font became very fuzzy... not as clear when i didn't embed the font. Also the more i tested with printing when I embeded the font, it still didn't resolve my issue. So not i'm at my wits end... i just want to send a display object/Text control to the printer and it print in exactly the same format as seen on screen. Seems odd as why this is SO difficult. I assumed when I send display object to my PrintJob instance it wouldn't try to get smart and reformat my text, just send it as a vector image and scale based on my ScaleType I've set.

Has anyone, as part of their web service security, attempted to deny the verb get on their web services but still be able to call them in their actionscript code? Ionly only have one client (flex app) that will call my web services, and part of the security, as I have done in the past, is deny any GETs on the WSDL file so someone can't easily determine all the methods exposed. I will be calling these services via SSL as well. However, when i call the load WSDL file, it obviously fails since that operation is a GET. All method calls are POSTS, so they'll/should work. Is this a situation where I would use a Proxy... just define the web service interface in my flex app... or am i required to always expose the wsdl file to my flex app? Thanks for any help!

I'll have to confirm what you can and cannot see by watching traffic when connected via SSL, i know the actual data is encrypted, which is all in the soap body, so I would assume the actuall method call is encrypted as well. I'll confirm... You definately see all off the soap message if not using SSL. However, and i do realize this is not an all encompassing security solution, but it's at least closing the front door to the house. Why expose more than you have to.

Actully, and i should have noted that in first post, i did try that,

Would it or could it have anything to do with the fact it's a

Not shown in the example, but i also exposed some public

successfully to those, just not my public string properties. So why
somethings bind ok, and others don't?

simply extend EventDispatcher.

[flexcoders] Re: TextArea htmltext parsing
Thanks for the update... i've also made progress in my spell checker suggest words algorithm. I'm basically using a modified version of the Levenshtein algorithm. I've found that with some minor tweaks it works great for 90% of mispelled words. I'm always looking to speed up the word distance algorithm Levenshtein provides. As far as UI, i just modeled the spell checker dialog window MS Word uses. It seams to be the most intuitive and what most people know. I would be curious to know your performance since everytime you want to suggest a word or check some text for bad spellings you have to go back to the server. I have the complete word list downloaded into my app and do all checking and suggesting based on that list. It's not perfect but no spell checker is. I get suggestions back within 100- 500 milliseconds, sometimes less depending on the length of the word. Now the question is, how well will this perform for me on a slower pc... i'm running a dual core 2.4ghz with 2gb of ram, i'm guessing on a slower pc i won't see as fast of a response. I plan to test to see how well it holds up. --Scott --- In flexcoders@yahoogroups.com, jmfillman [EMAIL PROTECTED] wrote: Scott, I'm sending the word Array to PHP for checking. PHP will check each word until it finds an incorrect word, then it will send the wrong word back, along with 10 suggestions. I'm not that good at PHP, so I hired someone to do this for me. We've worked out a fairly comprehensive logorithm that I'm quite pleased with the suggested words it returns. I'm still working on the Flex part, but how I envision this is that Flex gets the wrong word back, searches for it and highlights/underlines it. The user is presented with a list of words they can replace it with, or they can type in a new word (there are some good examples of similar stuff in the Flex Builder Help/Flex 2 Developer's Guide: Selecting and modifying text and Programming RichTextEditor Subcontrols). Programming RichTextEditor Subcontrols has a section near the end that has a find/replace Application that uses a RichTextEditor with a TitleWindow popup. Anyway, after correcting or adding the wrong word, I re-send the word Array to PHP for checking. Since I'll allow them to modify the text during the spell checking process, I resend the whole array until there are no incorrect words. Still thinking about how to give them the option to ignore words, without adding to their custom dictionary, so the spell check doesn't get caught in a loop of returning a word that the user says is correct, but they don't want to add.

[flexcoders] Re: TextArea htmltext parsing
No matter what you do to keep the formatting you still need the words in a plain text to run through your spell checker. Using the text property saves all the hassle of removing the html formatting. Thanks Adobe! Things like bappli/bcation come back correctly as one word. When I get the plain text i run this regex /\b\w+/gi; to parse out all the words. Removes punctuations and such, parsing just on spaces won't do. It's not 100% perfect but can finetune later. Once I know a word is not spelled correctly against my master word list and have the user's corrected spelling, i go find it in the htmlText and weave it in. The only thing that does NOT work really well is when a word is formatted differently in itself such as bappli/bcation. I currently lose that the first 5 letters are bolded... oh well. Can fix later. What i've found most difficult is the UI to highlight the word so a user has context. For now i'm just using the setSelection since i'm spell checking on TextAreas only. Not sure how you are doing suggestive words but havn't firgured that out yet, no algorithm. I'm loading a 120,000 word list into an array collection :)! I'm quite impressed how fast it is, loads in milleseconds when i split my text file on \r\n. Using the build in contains to validate each word. It's faster than calling any other web service.

[flexcoders] filterFunction issue with shared array collection in model / shared list
I have a shared arraycollection of value objects. Singeton, only one instance of this array collection.

[flexcoders] Re: Not able to generate GUID
Shaun, Thanks for the reply, good to hear some strong objections. First, i'm 99.9% sure this is the only app that will be generating ids for this database, but i do agree with that point. I have full control over all apps that would ever generate PKs for my db, i can make sure they won't conflict. I guess the point of a GUID is that I won't have collisions, or the possibility is so small, i'll take my chances, i'm not talking about millions of transactions. I did think about creating a temp id and the translating when it comes back down... but i'm trying to avoid having to send someting back down after i post and save my xml to the database. Another thought is that when my app loads, i'll just download X number of new ids that are available so i know (since the server gave them to me) they are unused, no collisions. I would say the stragety i'm trying to accomplish is not great for large teams, but in this case, i'm one developer, one database. If this product takes off and makes a ton of money it can always be redesiged later... for now, i'm trying to cut a layer out of all the server side to client ui mapping for sake of development time. --Scott --- In flexcoders@yahoogroups.com, shaun [EMAIL PROTECTED] wrote: Hi, scott_flex wrote: Thanks for the reply... i probably will look into writing my own implementation.

I still have to check pre-existence on my server side when i actually commit my changes to either run an insert or update sql statement. What will happen with things like collision handling or other applications wanting to insert into the database in future etc? Do they have to ask you to generate them a PK with your special actionscript function? ;) Why not do something simple like assign a tempid on the client, do the all the DB stuff on the server and return a list of temp_client_id=server_side_id key/value pairs, then put those values back in the xml on the client? Should be simple enough. At least that way you are not generating database primary keys in your client app. You can also implement a strategy on the server side so your client app never gets a real database PK. cheers, shaun

[flexcoders] Re: printJob on a textArea
Try removing the height from your text area object and just let flex determine the height automatically... ie, it doesn't have scroll bars itself. Then print it, you should get it all. You'll probably also want to set the width manually when you print it to the width of the print object... Flex prints at 72 dpi... so 8.5 X 11 paper is 612 pixels wide, assuming you are not counting for any margins. It appears flex will just print exactly what's on screen, scroll bars and all and it's not intelligent for printing text. So in my case, i transform the objects and put them in a better printing state before I send them tothe printer... because the format for printing is not always desired for how it shows on screen. I wish flex had better printing utilities for page breaks and making it easier to put more than one display object on a single page... but then again, you have a lot more control than trying to generate a html and print a web page...

Is there no automatic way to scroll to a particualar child object
inside a VBox?
I'm writing a tool that allows the user to select a child control
in
a vbox, (it get highlighted just like a row in a datagrid) and then
give them an up and down arrow to move the object up or down.
However, when you move a question up (using the vbox's
setChildIndex
method) it's moved up or below the window i want to programatically
scroll the selected child into view but only if it needs to.
Right now i've just writing my own code, basically reading the
scroll
postion of the vertical scroll bar and all the heights of the child
object in the vbox it's a hack though.
I think i've see a scrollIntoView method somewhere but it's not
listed on the VBox ui object.
Thanks for anyones help i could be missing something really
easy.

[flexcoders] determine when list of dynamically added UI objects are fully rendered?
When you programmatically add many UI objects, 25-100 to a display list, VBox, DataGrid or whatever, when can you determine all UI objects have been fully rendered? I'm looping through an xml file, and for each row/node I'm creating a new instance of a custom display object and adding it as a child to a VBox. The looping logic takes milliseconds to run but it could be 3-4 seconds before the actual UI catches up. How do I know when it's done rendering all my child objects? I want to display the busy cursor and remove it when they are all done rendering. Listening to updateComplete or creationComplete events don't necessarily work. Multiple updateCompletes get fired for different stages in the creation process and creationComplete does get fired before UI is done drawing to the screen as well. Any thoughts? Am I just programming something wrong?

[flexcoders] help creating XML object with variable data
how come the following does not work
var myString:String = Test data;
var myXml:XML = Option value={myString}/option
//not string substituion occurs, {myString} is just inserted as a
literal.
but this does:
var myString:String = Test data;
var myXml:XML = Option{myString}/option
// {myString} is property repaced wiht the text Test data... as I
would expect.
For some reason i can't bind or use the {} notation when creating an XML
object and trying to assign attributes of an element... but it does work
when i use the {} notation to insert text between the begin and end tags
of a node.
Am i doing something wrong? Or is this a limitation seems silly if
it is.
[flexcoders] Re: help creating XML object with variable data
Thanks! That did it... makes sense why it did what it did when i had
quotes... just in case i really did want that as a literal.
I'm a newbie at flex... if only i could get my company to use it more
for our web apps unfortunately we have MS Gold certified blinders
on sometimes. Go Flex!!!

Hi,
You don't need the quotes when assigning it to an attribute,
myXml:XML =
Option value={myString}/option should do the trick.

[flexcoders] retreiving object height after adding it as a child object
How or when can you retreive the height of a display object when you add it to your vbox or hbox. I have code that looks like this: var myObject:myControl = new myControl(); // call the public load method with xml to set some text // on myControl and other display values. myControl.load(myXml); myVBox.addChild(myControl); trace(myControl.height); // returns 0 if I add an updateComplete event listener to myControl, i normally get 4 calls to the handler since there are several phases in the layout. Which one is the last one? In theory the next one is the last one, i realize that. if i listen to the creationComplete event, it's only called once but it's dispached before it finished it's truly done sizing itself. even doing a callLater to get myControl's height doesn't work, too soon. SO at what point can i be sure that i can retreive the myControl.height property and know it's the final height?
[flexcoders] How do i determine when all rendering is complete for added objects in for loop
I'm parsing an xml document and adding child objects to a VBox. The child components all have a text component which receives text that is set to the htmlText property. So depending on the text the height of the control varies. However, i need to know the height of each control i'm adding (for printing reason) but i have no idea how to get it right away, at least when it's added to the VBox, ideally at least. I've tried listening to the updateComplete and creationComplete listeners to each control added, then in theory when I handle the event i know the object is done and i can finally use the object.height property to get it's height in pixels. If you attempt to the the object.height proprety to early you get zero or something that is not reflective of the final height. However, listening to the updateComplete, you get multiples calls because it's dispatched several times throughout the creation of the child object... how do you know which one is the last one? this may not even be the best way to do it. The creationComplete is only sent once but it's sent before it finishes rendering the text box which controls the height. So without intentionally waiting a few seconds for the components to load, how or when can i be sure all the child components have finished sizing themselves from which I can get a true height value from them? Hopefully this makes sense, i'm not quite even sure what to search on. I'm a newbie to flex and love it so far, main expierience in asp.net.
