[flexcoders] Using Vector Collection as a Datasource??
Hi guys, We're performing some labor intensive calculations with arrays and it is really slow. I've read the threads here describing the array collections being slow, so we decided to switch to using a vector collection. All great, works faster, however it doesn't behave as expected and we can't figure out how to use the vector collection as a datasource as you would with an array. Are Vector collections ready to be used or still a work in progress? Can anyone provide an example or a link to how we would go about using Vector collections properly? We've searched for days and have found all the very limited Adobe content. Thanks everyone!! -- Blair Cox
[flexcoders] Flex Builder 3 on Mac and Win at same time?
Hi folks, Bit of an issue here. We have a project that requires us to begin working with an ASP.net server. I'm currently using the Mac version of FB3 and so far I haven't been able to determine how to continue using the Mac version while creating a new project tailored to ASP? When we purchased FB3, I downloaded both the Mac version and the PC version. I have Parallels installed on my Mac, so I'm running WindowsXP as well, can I install FB3 on the WinXP side without causing any issues? Technically, it is the same as installing the program twice on two machines, but how else can I get around this? Am I missing a way to continue using the Mac version and to connect to a remote ASP server without causing problems? Haven't figured it out yet. Thanks,
[flexcoders] Textarea, why the blue border?
Everyone, Why is there a blue border shown when using a textarea and it has been clicked on? To show it is in focus? Great, but why? How can this be removed? No, switching to Gumbo is not an option. How would you display a few paragraphs of text within you applications? Dis the designers of Flex believe it would never be used to show more than a couple lines of type? Thanks.
[flexcoders] Please Help: Shift data Up|Down in array/datagrid
Hi everyone, hope someone can offer a suggestion to solve this, or at least let me know if it possible within Flex/ActionScript. Here is my sample data: Date Var1 Var2 - Mon 34 45 Tues67 87 Wed 83 12 Thurs 89 23 Fri 12 98 ... ...... Lets say there is more data, but this is what is visible at the moment. Question: How could I adjust the Var2 column by essentially moving it up or down within its column? So if I moved it down (perhaps adding a null reference to the first row) 45 would appear in the Tues row, however Var1 would not be changed. If we were to move it up, the 45 would be removed and the 98 in the Fri row would move to Thurs. At best, it would be good to be able to do this with a slider control and have it return to normal without destroying the original data loaded in the array. I was thinking of a custom filter function, however could not find any references that indicated it could be used in this manner. Would IViewCursor be capable of doing this? As long as the datagrid showed the changes, I would be able to perform the necessary calculations on the adjusted data - correlation. Any thoughts whatsoever would be greatly appreciated. -- Blair
[flexcoders] Dynamically control chart data
Hello everyone, I'm trying to learn how I can manipulate a chart to perform some very simple calculations such as averaging data in a series or adjusting data ranges. I was thinking of the filterFunction, however I'm not sure how to implement it. I don't want to permanently change the data, just to apply mathematical filters which slightly alter the appearance of the data. Any suggestions? Thanks, -- Blair
[flexcoders] How to: Select range in Datagrid to set range in Chart?
Okay, I'll do my best to explain what I'm trying to do and see if anyone can point me in the direction of a good url and sample - What I would like to do is select a range of data within a Datagrid, so lets say 10 items out of the list 20. Than whatever is selected in the Datagrid, appears in chart. It is merely a graphical way of filtering a date range of data. Currently in my example, I select the beginning and ending dates. So all I would require to modify this is to be able to pass along the the first and last entry selected and define which column will be used. Any ideas? Cheers.

[flexcoders] How to use anchor and caret selection of a chart?
Everyone, I want to be able to select within a chart and pass the anchor and caret result to a variable. Specifically by selecting an area within the chart, the xValue being a date range will pass the begining and end date, as a string to any value I choose. I may just want to output the anchor and caret to a text field, doesn't matter. What I need to know how to do is out the anchor and caret while defining that the xValue is to be used. I've gone through the Adobe manual examples and can output the selection to a datagrid, but I need a little more control. Entering Flex anchor or caret into Google yields three results. It is a poorly documented function. Thanks, -- Blair
[flexcoders] Help: Hide AxisRenderer
Hi All,
I've been working on this for some time. How to turn on and off
multiple y-axis labels. I can do it, however when you make an
AxisRenderer visible=false, the space it occupies remains. What I
need to do is add and remove the additional y-axis labels and re-size
the chart to accommodate the room occupied by the additional axis, or
restore it when they are removed.
Thoughts on how this could be accomplished?
mx:verticalAxisRenderers
mx:AxisRenderer placement=left axis={v1} /
mx:AxisRenderer placement=right axis={v2} /
mx:AxisRenderer placement=right axis={v3} visible=false /
/mx:verticalAxisRenderers
Thanks.

[flexcoders] Possible? Charts - CatergoryAxis Group by Day/Time?
Thought I would ask the experts. I have a simple chart displaying data for about 60 days. The data consists of events which either occur once a day or multiple times a day. I've been asked that if an event occurs multiple times on a single day, to stack or group them on the chart. Stack may be the incorrect term, they would simply be represented vertically for a single day. If the data is identical, it would be represented at the same point. Is this possible? How? Thanks for the help. -- Blair
[flexcoders] Help: filterFunction and Dates
Hi everyone, With the help of another poster I was pointed in the correct direction to solve a problem I have: The two links were helpful: http://livedocs.adobe.com/flex/3/html/help.html?content=controls_12.html http://blog.flexexamples.com/2008/03/12/using-a-combobox-to-filter-items-in-a-datagrid-in-flex/ Based on the above information, I was able to accomplish all my tasks, except being able to sort dates. Problem #1 - How to format the date so that it displays as 2008-10-01. I have it all the way up to 2008-10-1. Apparently the 'day' is represented as a single digit. That won't work - using a MySQL db. Problem #2 - I am apparently lacking in my knowledge of ActionScript to correctly write the proper script to filter the date. What I can't seem to figure out is the correct syntax for working with dates, or perhaps simply a string or number containing - dashes? Sorry, I'm not providing code you to ponder over, I really only need a reference to start with so I can learn as I go. I've been searching but have not been able to locate a reference which deals with sorting dates? Thanks,
[flexcoders] Charts - How to filter dataprovider by date?
Hi everyone, I've spent hours over several weeks looking for a hint of an answer to this, perhaps my situation is unique. I have a database, that through necessity, has the data for multiple items, we'll call them different tests. Now if I use this database for a chart's data provider, it will of course display along the x-axis, all entries which currently exist. So if there are 10 entries, I'll get 10 data points, whether anything is plotted on the y-axis or not - just a default line chart, no other parameters set, it's not important yet. Okay, so lets say that out of the 10 currently existing data points in the db, only 5 are relevant to me at the moment. I've figured out how to select the five I wish by defining them in the y-axis series, however the remaining 5, still of course exist in the data provider and are shown along the bottom of the chart and because the data is not relevant to my selection, appears as zero, no data. I've probably lost you, so let me explain what I want to do. I would like to be able to filter the data presented in the data provider, before the chart is rendered. So if I wish to show only 5 of the 10 available points in the table, I can do so. Now, can this be done simply by manipulating the x-axis or is it required to be done perhaps with sql calls to the database. How about a hint about how I can filter or control the data delivered in the data provider. Thanks,

[flexcoders] Combobox to show table columns?
Just wonder if anyone has a trick to dynamically populate a combobox with the column labels of a table or XML source. I seem to only manage to retrieve the values of the rows, not the actual column name. I know I manually list them, but this defeats the purpose if the table were to change. Ex. So instead of showing the value ALB_RLU, I want ALB_RLU to be a selection in the combobox. response #8722; data #8722; row idATP_Calc82/idATP_Calc UC1/ ALB_RLU33321./ALB_RLU ALB_ATP213213./ALB_ATP ALC_RLU213./ALC_RLU Thanks,
[flexcoders] Help with Chart dataprovider
Hi, I've been trying to figure this out for a while now. I have a
basic chart that I want to be able to select a different data source
for each series. I have a test app where all I want to do is change
the charts dataprovider via a combo box;
mx:ComboBox id=choosekit x=10 y=23 width=210
dataProvider={samplepoint}
labelFunction=getListLabel prompt=Click to Select...
change=trendingchangeHandler(event) selectedIndex=0
/mx:ComboBox
...
mx:LineChart x=281 y=14 id=linechart1
dataProvider={samplepointdp} showDataTips=true
mx:series
mx:LineSeries id=series1 displayName=Series 1
yField={series1dp}/
mx:LineSeries id=series2 displayName=Series 2
yField={series2dp}/
/mx:series
/mx:LineChart
mx:Legend dataProvider={linechart1} x=188 y=309/
...
[Bindable]
private var samplepointdp:String
private function trendingchangeHandler(event:Event):void
{
samplepointdp = choosekit.selectedItem.Test_Kit_Used;
}
...
If I statically set the dataprovider and load the app, it connects to
the db and populates the chart. I can then use combobox's to change
the yAxis of each of the series, works as expected. Now I'm assuming
the same can be done with the dataprovider, but I see that when the
app first loads, there is just the slightest pause while the chart
connects to the db and loads. So I'll assume that when I change the
dataprovider in the app, I must then refresh the chart to load the new
data? But how?
Thanks,
[flexcoders] Change dataProvider at runtime?
Does anyone have experience with changing a dataprovider at runtime? Scenerio: a grocery store Database has four tables, one for Produce, Dairy, Meat and Other. Each of the tables is a different arrayCollection/HTTPService I want to be able to have four comboboxes, each able to point to any of the four arrayCollection's, therefore to change the datasource of each series in a chart. Why? Because it would allow you to compare values of different data sets in a single chart. I did not expect this would be such an issue. If anyone can provide any information at all, it would be a huge help. Thanks,

[flexcoders] Change Chart Data via Combobox: redraw?
I did not think this would be an issue, but I simply cannot understand
why this won't work:
I'm starting with a simple test, so no real code to speak of, but this
is what I'm doing.
A simple line chart, with three series. I have three combobox's. Each
series calls a unique dataPrivider (works fine when placing static
values) based on the selection in the combobox;
mx:LineSeries id=Series1 displayName=Series 1 yField=DB_row
dataProvider={combobox.selectedItem}/
I have a label to provide a visual output of the cb selection in the
app and it is correct. I thought this would be the same as statically
typing in the value, but it appears the chart is not redrawing, yet
many on the examples I've found in the Adobe pages make similar
adjustments in a similar manner, no method to redraw. Very confusing.
So, can anyone point me in the direction of a sample where you can
change a charts dataProvider and yField within the application via a
combobox selections?
Thanks,
[flexcoders] Combobox with multiple data sources?
I've been reading the blogs all afternoon and haven't found an answer to this (probably because it's really simple), but what I want to do is populate a combobox from two data sources. One will be from a small array in the mxml, the other will be from the database and dependant on what the user has entered, but they must appear in the same combobox. I've been looking at hierarchical data providers and GroupCollections, but just can't see how to fit it together for my use. Thanks,
[flexcoders] Printing and PDF creation
Just wondering if anyone could provide some information on general printing concepts and creating PDF reports from an application. With regards to printing, I really only need to allow the user to correctly print what is displayed in their browser - the application interface. As a bonus, allowing the user to print a report would be even better. I've heard a lot of talk about printing DG's, but how about printing charts? If you could pass along some links to read more on this, it would be a great help. PDF creation - Is it possible to create a pdf directly from the application within the browser (not AIR)? An example would be within Goggle Analytics, you can create a PDF report containing all the data and charts displayed online. Nothing complex here, simple plain reports full justified, center aligned - the way the business folk like it. Cheers, Blair
[flexcoders] Using Create App from DB - Saving decimal number 123.123??

[flexcoders] NaN and Infinity showing in output - How to modify?
I seem to have trouble explaining myself here, hard when you are just
learning. Perhaps this will be better.
Is it possible to remove, change or hide any label or text output that
displays NaN or Infinity?
I'm performing a very simply calculation where the user enters a
number in a form and it is calculated and displayed. Simple and does
what I need. In some instances, there are more variables required and
until they are provided, the output display NaN or Infinity.
How could I easily adjust these? It could be a default display of
zero, it could be to display nothing, whatever is the easiest and most
straight forward method.
Below is only an example of how I'm taking the user input from the
form and passing the variable on to the Label text output.
mx:Number id=myNumber{Number(userInput.text) * (1 +
Number(otherUserInput.text)) * 1 /
Number(otherOtherUserInput.text)}/mx:Number
The answer is output to:
mx:Label text={PrepForDisplay.format(myNumber)}/
Thank you, any assistance you can provide would be welcomed.
[flexcoders] ViewStack and Combobox
Here is my situation,
I have a combobox and a viewstack. The combobox's dataProvider is XML
generated by a php script retrieving information from a db.
The database has two primary entries. The first is a location, the
second is a type of test performed. These are inputed by the user
elsewhere in the application. When the user views the combobox, they
see the list of site entries.
Upon selecting the a site, the viewstack should change to show the
related test information. Should be pretty straight forward. The
problem comes when I want to pass the string value of the test to
viewstack - they have the same names.
As a test of the viewstack, this works fine:
dataProvider={viewstackTestKits.getChildren()}

[flexcoders] Please help a newbie :) - ArrayCollection
Hi, I'm sure this is incredibly simple, however I'm having trouble
figuring it out.
I have a php script which connects to a db and returns standard xml.
What I want to do is choose which children from the repeating elements
to use.
Found this example and it works:
mx:Repeater id=pointRepeater dataProvider={samplepoint}
mx:Text x=364 y=244
text={pointRepeater.currentItem.Sample_Point_Name}/
/mx:Repeater
My ArrayCollection is called 'samplepoint'.
XML is response.data.row
So lets say I have a combobox that I would like to specify which of
the child elements of my xml data I wish to use - how would I do this?
I've tried dataProvider={samplepoint.Sample_Point_Name}
The only way I could come close was to use
labelField=Sample_Point_Name, but this doesn't do much for me, since
I need to specify a data value.
I have looked to great length, I must be missing something. Thank you.
[flexcoders] Re: Please help a newbie :) - ArrayCollection

item.Test_Kit_Used +
);
}

[flexcoders] Newbie Help: Resolve a multiname reference unambiguously...
Hi, Totally a newbie here, so please excuse my ignorance. I've spent some time working through this problem and this is where I am at. I want to be able to make multiple calls to my database tables. I did use the create application from database to generate the php code to create the xml I need. Works great for my needs, I just need to be able to make calls to the server. I used the generated datagrid to display and manipulate some data in my application, so I would like to keep the original part, just add on to it. From what I gather, it is not possible to reference HTTPService twice. Currently it appears in a ActionScipt file as - private var gateway:HTTPService = new HTTPService(); This part is the original datagrid application. And again in a data block within the mxml file - mx:HTTPService id=SamplePointCollect url=http://localhost/debug/Points.php?method=FindAll; result=resultHandlerSP(event)/ I added this to populate a combobox where the code for the datagrid exists, except this combo references a different table than the datagrid connects to. How would I give an instance of HTTPService a unique ID - or populate an array in a different way? Thanks,
[flexcoders] Re: Newbie Help: Resolve a multiname reference unambiguously...
Okay, I figured out that you can assign a different ID to the instance of mx:HTTPSErvice.

[flexcoders] Help with Module Loader [Flex Builder 3 Bug?]
I have a module which contains a datagrid that connects to the database. It works, no issues. The problem comes when the Flex Builder 3 in design mode access the swf reference in the module loader and displays a popup saying there is an http access error, obviously because the design view cannot access the php routines, so displays the connection popup. The problem is it does not go away and renders design view useless. Has anyone encountered this? Do you know how to correct it? To replicate, create an application from a database and move the generated mxml contents to a module. Close Flex and reopen - the error will now appear. Thanks,

Adobe lists examples very close to what I'm doing except my module connects to a db - http://livedocs.adobe.com/flex/3/html/help.html?content=modular_5.html I went through the preferences and changed some settings, the one that may have made the difference is telling Flex Builder to use the internal browser (default setting). Closed FB and re-opened, everything appears to be functioning normally. I don't get a preview of the module in the parent application, but that is fine with me.

Isn't the Internet just nifty! Answered my own question. For anyone reading this, hopefully this link still exists and will answer your question :) http://dougmccune.com/blog/2007/06/03/save-a-snapshot-image-of-a-flex-app-without-a-server/

Hmm, yup that sucks. I'll be using PHP5 and MySQL 4.1, any tips on where I could look for some tips on accomplishing this? New territory for me.

I can't remember if there's some way to do this natively with as3, or if I was doing it with a swf2exe tool, but either way, it sucks. Send the data serverside and regenerate it there. Your serverside language should have some packages to create images or pdfs or something. It's annoying to generate the report in two places, but it's the only way I know how to do it.
[flexcoders] Re: User loads CSV file
So if I had the user upload the file to the server and specified what the file should be named as, could I then load the contents of the file and store it in the MySQL database? I see all kinds of information about XML files, however I would need to write an app to convert a CSV to XML to load... Doesn't have to be that complicated. Cheers. How would you normally acquire bulk data from a user? These users would be logging data recorded from a measuring device. The device software exports the data as a CSV, to recap.

Sorry, It would initially be for a web page. Later the application will be migrated to AIR. We are using PHP and MySQL for the database, if that helps as well.

[flexcoders] Re: User loads CSV file
Okay, the back story is we are creating a completely new application based on a very complicated Excel based spreadsheet an engineer designed to record the data collected from users. The program essentially trends this data. It will be entered manually as well as collected from the device as I mentioned. The part I'm trying to spec in my head is how I'll allow the user to take their CSV data file and add it the application? I am new in this area, so I'm in the learning curve. There will be so much data collected that setting up a MySQL database to store it will be necessary. So I need to understand the best way to let user upload a file and for me to be able to add the data to the database. Everything would have to done by the Flex application - or php scripts within flex. Not sure how else to explain it. You could provide a general example of importing data to a database from a CSV source. It would be saved directly to the database, then be accessible via other modules of the application to trend the data into a graph. The application will just be a graphical version of the spreadsheet really.

[flexcoders] User loads CSV file
Hello everyone, I'm new here, so go easy on me. I'm essentially just beginning with Flex, needless to say, I'm ready to learn. Using Flex Builder 3. I've spent a few hours looking through many of the flex sites I've come across and the mail archive for this list and can't seem to find the information I'm looking for. What I need to be able to do in our application is allow users to import a CSV file so that we can save it to the MySQL db, then do the work require to the data. The formatting of the CSV file will be consistent and previously arranged. The db will contain the same fields, it's just a matter of collecting the data. Right now, the file must be a CSV, since this is what the measuring equipment exports as. It needs to be as simple as possible for the user. If you could offer some hints or put me in the correct direction of an example or tutorial, it would be appreciated. Cheers, Blair
