[flexcoders] Installation on multiple machines (was: Flex Builder 3 on Mac and Win at same time?)
Installation on multiple machines If you own, or are the primary user of a single-user Adobe product that is installed on a computer at work, you can also install and use the software on one secondary computer of the same platform at home or on a portable computer. However, you may not run the software simultaneously on both the primary and secondary computers. Okay, that is great, but the only reason I need to do this is because the version for the Windows platform does something the Mac version does not? I just want to make sure I don¹t mess up my primary copy, which is on the Mac. I don¹t need to run two instances of FB3 at the same time. Or Does anyone know how to connect to an ASP.net server from the Mac version of FB3? Thanks, -- Blair From: cox.blair blair@luminultra.com Reply-To: flexcoders@yahoogroups.com Date: Fri, 09 Jan 2009 14:21:38 - To: flexcoders@yahoogroups.com Subject: [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,
Re: [flexcoders] Re: Installation on multiple machines (was: Flex Builder 3 on Mac and Win at same time?)
I only thought I required the Windows version because when you start a new project and select ASP.net as the server, it requires the dev server or IIS to be local. I would like to stay away from third-party add-ins for communicating with the ASP server. I have to follow the rules of the client¹s IT department. Minimal boat rocking here.

You can use the Mac version of Flex Builder to build a SWF that connects to ASP.NET using WebORB. Why do you need the Windows version of Flex Builder?
Re: [flexcoders] Re: Installation on multiple machines (was: Flex Builder 3 on Mac and Win at same time?)
No idea, new territory for me. I¹m just going on what I¹ve found in the documentation and the options shown when creating a new project. Lets switch the topic slightly: How would you go about creating an application where the server data is handled by someone else and you have very little to no control of it. You pretty much have to deal with what they provide. It¹s an ASP.net server with a preference to delivering XML data. There is a slight chance we could use SOAP/web services. We¹re talking an industrial setting as well. If you have IT experience in this area you¹ll understand. I just read a blog on setting up WSDL, anyone have any experience here or some suggestions? http://www.flexlive.net/?p=79 -- Blair From: Sam Lai samuel@gmail.com Reply-To: flexcoders@yahoogroups.com Date: Sat, 10 Jan 2009 02:58:02 +1100 To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Installation on multiple machines (was: Flex Builder 3 on Mac and Win at same time?) There's no problem with running both versions technically - they are completely seperate from the app's perspective. What's the error? And out of curiosity - what does telling FB3 what server tech you use get you anyway?

Re: [flexcoders] How to: Select range in Datagrid to set range in Chart?
What would be really nice is to simply select the range directly from the
initial chart, since when first loading the dataprovider, the entire range
is loaded. Every time I try to implement filtering before retrieving the
data, I get a null reference error.
private function processFilter(item:Object):Boolean { return
item.Date_Collected =
dfconv.format(linechart1.selectedChartItems.xValue.caretItem).toString()
item.Date_Collected =
dfconv.format(linechart1.selectedChartItems.anchorItem).toString();
If I could simply define the first and last item selected in a chart
multiple selection, it would do what I need. Any suggestions?

Subject: [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.

Re: [flexcoders] Re: Help: filterFunction and Dates
Many thanks Tim! I dropped the DateField component and tried a simple text box, plus your suggestion and it works. So even though the database table field is defined as a Date, the AMFPHP is bringing it in as a string. The key part to this was .toString() Okay, so now back to an original dilemma. When using the DateField component, I get a full UTC date output. I¹ve been able to use labelFunction and DateFormatter and a couple others to get close to the required format of -MM-DD, but what I end up with is -MM-D, because apparently 1 through 9 are not represented with a leading zero (01, 02, etc) If I cannot match the string in the db, it won¹t work, correct?

This can be done automatically by using [RemoteClass(alias=com.myDTO)] in a VO class; but that's a more involved topic. So, let's take this one step at a time. What is the data type of item.Date_Collected? You can find this by inspecting the the object in debug mode. If it's a string, try this in your filter function: return item.Date_Collected == dfconv.format(wholeDate.selectedDate).toString(); The key is to compare apples to apples. If one side is an apple and the other is an orange, you have to turn the orange into an apple before comparing. -TH
Re: [flexcoders] Charts - How to filter dataprovider by date?
Hi Maciek, Still new at this, so I¹ll answer the best I can. The chart is getting it¹s data from a RemoteObject using amfPHP. I have an arraycollection and result handler pretty basic stuff. It appears to accomplish what I need it to, I¹m sure there are more elegant means. I¹m investigating the filterFunction. Most of the blogs speak of sorting a datagrid, though a chart should function the same way, yes? I would prefer to perform the sorting/filtering, whatever the correct term is, within Flex rather than require a PHP script to pull specific data from the database. The user will eventually use all the data available in the table, so there is no reason why it should be available up-front, then simply sorted.

I use a Mac, however I¹m also coming from the graphic design / web development side. I, a long time ago, was a diehard PC user. Actually I was a technician, skilled in the art of fixing all things WinTel. Then one day, kicking and screaming, I was introduced to the white computer with the distinctive bitten apple logo. Reluctantly, over time, I came to the understanding that I could actually get work accomplished without requiring an A+ certificate, numerous Microsoft Certs or an on-call IT support team. The damn thing just worked! Can you believe that? Amazing... Actually, using the OSX operating system natively allows you to work with files as they would appear in an Apache server. Being a Unix based OS (closer relative, not distant cousin like Winx), you can do things that would require extra software, patches, etc on Windows.

Hey Blair,
For dates, it's important that you use the Date() data type. Some use
strings instead. Since you're using AMF, using strongly typed date
objects for the VO's is the cleanest way. The reason that I say to use
Date(), is because that the Date.time property is stored as the number
of milliseconds since 1970, IIRC. Because it' numeric, you can easily
perform sorts. For formatting, you can use a dateFormatter with
-mm-dd as the formatString. This leaves the underlying date
alone, but displays it in whatever format that is specified.

Re: [flexcoders] Re: Change dataProvider at runtime?
Thanks everyone for your replies. I must admit I¹m not yet up to speed on
all things Flex.
Nicholas mentioned combobox.dataProvider = anotherone? At runtime. From my
perspective I figured I could do it like this;
Chartdp = combobox.selectedItem; or linchart1.dataProvider =
combobox.selectedItem
mx:LineChart id=linechart1 showDataTips=true
dataProvider={chartdp}
The combobox would list all the available arrays. This does not work
however. (I tried selectLabel as well, changing to String and Object in AS)
Tracy mentioned about not binding directly the lastResult and use instance
variables. Yes, I do believe I am doing this correctly;
[Bindable] private var ALCTrending:ArrayCollection = new ArrayCollection();
var ALCgateway:HTTPService = new HTTPService();
ALCgateway.url = Kit_ALC.php?method=FindAll;
ALCgateway.addEventListener(ResultEvent.RESULT, ALCresultHandler);
ALCgateway.send();
private function ALCresultHandler(e:ResultEvent):void{
ALCTrending = e.result.response.data.row;}
So, if the above is correct and I¹m not grossly overlooking something, I
believe the best solution for our specific requirements is to combine all
the tables into one. While perhaps large and not as efficient as it possibly
could be, all the data must be analyzed together anyway. Last night we
calculated it would take at least 3-5 years for a customer to populate the
database to the point where there would be a performance hit. Each customer
will have their own isolated database.
Cheers, thanks again for the help :)

Subject: Re: [flexcoders] Re: Change dataProvider at runtime?
If you're not going to change the column names when you change
dataproviders, a third option might be to create a database view to query
against. Have the view stitch together the appropriate columns from each
table into the view's columns (probably via that Union query), then query
the view to get the data that is filled into the dataprovider. That way you
leave the complexity where it already is, in the the database, you wouldn't
need logic to switch out the dataproviders, etc.
Re: [flexcoders] Re: Change dataProvider at runtime?
Okay, try this scenario: Can you change the dataprovider of a series or chart on demand from within the program while it is running? So no matter why I¹m doing it, I have say four completely different dataproviders collecting data from say a static in-line source, a static XML file source and a couple dynamically generated by whatever means. Then do this, have four primary combobox¹s each related to a series in the chart. These first combobox¹s will select the dataProvider of each series (this works when statically set). Then you have an additional four comboboxs which will set the yAxis of each chart series based on the selected dataProvider (conditional combobox which changes based on what the first combobox has been set to). See what you have now? The ability to analyze different data sets from different sources within the same chart. The way it works now, the assumption is that this data can always be lumped into a single array, which isn¹t always the case especially when dealing with an application designed for an engineering application. It would just be far simpler to be able to change dataprovider on the fly and tell the chart to update or reload. So how could this be done? Reload or recreate the chart based on a click or change event? -- Blair From: Tracy Spratt [EMAIL PROTECTED] Reply-To: flexcoders@yahoogroups.com Date: Thu, 21 Aug 2008 19:59:07 -0400 To: flexcoders@yahoogroups.com Conversation: [flexcoders] Re: Change dataProvider at runtime?

Re: [flexcoders] Re: Change dataProvider at runtime?
Hi Amy, Well, I have complete control over the database. This where we might have a problem, it seemed at the time that creating a table with around 200 columns would be unreasonable. A table was created to handle each of the products. Each product has as many as 20-30 columns and for the most part, do not relate to each other. I pondered over normalization for over a week. But now look at the issue... Hmm, what would be the issue in creating a single arrayCollection from all sources? How would this differ in any way from loading a single enormous array directly from the db? Looks like I¹m down to two options, recreate the db and over half the constructed application to deal with the changes in code, or figure out a way to combine the tables within the application or the Union query as you suggested. -- Blair From: Amy [EMAIL PROTECTED] Reply-To: flexcoders@yahoogroups.com Date: Thu, 21 Aug 2008 18:32:56 - To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Change dataProvider at runtime? --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com , cox.blair [EMAIL PROTECTED] wrote: Does anyone have experience with changing a dataprovider at runtime?

Re: [flexcoders] PHP vs. Coldfusion 8 for beginner?
Thanks Guilherme, we¹ve just come to the same conclusion. Given the cost of implementing ColdFusion and the limited number features we are currently interested in using, we simply can¹t justify the switch. PHP appears to be able to do everything we want to do and it is rooted deeply in our current website technologies (Apache, MySQL, Joomla, Drupal, etc). I say I¹m a novice, but I do have a working knowledge of PHP, I can at least sit down and read through a script and understand what is going on. Best to build on that knowledge than to switch to another language, again. Overall though, I do find them all to be very similar, so that hasn¹t been an issue. Biggest advantage with PHP is the community and resources behind it. I guess I don¹t find this subject too off-topic because it does seem important to know how your Flex application actually communicates with the server and database.

If the format function is a custom function you have written, you could just
have it check whether you like the result it is about to return, and if not,
return something else. If that is not the case, I believe that you should be
able to put tests into your binding statement.
You could test for NaN with something like this:
mx:Label text={(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber)
}/
I'm not sure about infinity, but I assume that you can test for this by
looking for the greatest possible value of the number. Assuming that you
have set up the variable maxValue to contain that value, you should be able
to do something like this:
mx:Label text={(myNumber maxValue) ? 0 : PrepForDispl ay.format(
myNumber) }/
If you put the two together, it would look something like this:
mx:Label text={(myNumber is NaN) ? 0 : (myNumber maxValue) ? 0 :
PrepForDispl ay.format( myNumber) }/

Subject: [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(otherUserInp ut.text)) * 1 /
Number(otherOtherUs erInput.text) }/mx:Number
The answer is output to:
mx:Label text={PrepForDispl ay.format( myNumber) }/
Thank you, any assistance you can provide would be welcomed.

Just one more question. The zero works for me, but I¹m sure I¹ll be asked to
make it blank. Any hints as to how this could be accomplished? Coming from
the Flash side of things, all I would be looking to do is change the alpha
value of the label to zero if the value was 0.

If the format function is a custom function you have written, you could just
have it check whether you like the result it is about to return, and if not,
return something else. If that is not the case, I believe that you should be
able to put tests into your binding statement.
You could test for NaN with something like this:
mx:Label text={(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber)
}/
I'm not sure about infinity, but I assume that you can test for this by
looking for the greatest possible value of the number. Assuming that you
have set up the variable maxValue to contain that value, you should be able
to do something like this:
mx:Label text={(myNumber maxValue) ? 0 : PrepForDispl ay.format(
myNumber) }/
If you put the two together, it would look something like this:
mx:Label text={(myNumber is NaN) ? 0 : (myNumber maxValue) ? 0 :
PrepForDispl ay.format( myNumber) }/

Re: [flexcoders] NaN to return a string?
Turns out showing a zero could be implied that the calculation was a zero.
This is bad, especially if the result is actually zero. Is there any way to
return a string rather than a number?

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Hmm, sorry the last post left a part out, it was shown lower down:
mx:Label ... text={isNaN(mynumber) ? 0 : PrepForDisplay.format(mynumber)}
... /
Adding the ³² as you stated, returns an error for mx:Label, ³² or ³/².
The zero is what is display in the application, if I could provide a short
string instead, it would be ideal. Even if the initial default text of the
label was ³whatever² until a calculated value was entered. But there are
many, many of these calculations to perform and I would like to find the
simplest answer. Close though, thanks for the help.

Re: [flexcoders] NaN to return a string?
Doh! Only way to get better at this is to keep working at it. Thanks for all
three of your great suggestions. The powers that be want a note, so we¹ll go
with that that. I¹ll find uses for the other options for sure.
Cheers!

Sure, just replace the 0 with whatever text you want, putting it inside
single quotes since the entire statement is inside of double quotes. Since
you are setting the value of a label, what ever you put in is going to be
cast to a string anyway.
Try something like this:
mx:Label id=display text={(isNaN(myNumber as Number)) ? 0 :
PrepForDisplay.format(myNumber)} visible={display.text != '0' amp;amp;
display.text != 'In,fin,ity.00'}/
Note that you need to give the Label component and id, and use that id to
refer to it in your statements within braces.
By the way, as you are no doubt noticing, the larger point here is that
braces are not just for binding, but can contain all sorts of ActionScript.
Finally, the reason that there is amp;amp; instead of is that we are
inside of MXML, which is to say inside of XML, and we cannot use the
character there, but must escape it.
