Flex 4: How 2 Set Application Height/Width with Script?

I am new to Flex 4 and going through the 3 to 4 migration pain.
I need to set the size of my application programmatically. In Flex 3, I did it this way:
mx.core.Application.application.width = theWidth; (equivalent for height).
I can not figure out how to do this with Flex 4. Searched high and low.
Help, please! TIA
Bruce

You can use this.height and this.width properties.

[ASK] Set Network Address Restriction With Script

Hi all, i have a question about set network address restriction.. if i post in wrong category i'm very sorry about it because i don't know where i supposed to post this..
i need to set network address restriction to every user in my tree..
the problem is there is hundreds of user that i need to set the restriction.. i think it will take a lot of time if i do it one by one..
i created the user with script, and i want to ask whether there is a command to set network address restriction with script or maybe there is another simple way to set network address restriction..
thanks..

Is the restriction going to be the same for all users? Depending on what
"script" you use, you should be able to also set the restriction at the
same time - its just another attribute value to set.

>>if i am rendering html from MemoryStreamor string in webbrowser control in wpf It's not applying this css
Yes it does. If you for example add background-color: yellow; to the stlyle you will see that the page turn yellow:
strHtml = strHtml.Replace("<body>", "<body style=\"-webkit-column-width:800px; background-color: yellow; overflow:visible !important; -moz-column-width: 800px; column-width: 800px; -webkit-column-gap: 0px; -moz-column-gap: 0px; column-gap: 0px; -webkit-column-rule: 0px solid #000;-moz-column-rule: 0px solid #000;column-rule: 0px solid #000; height:800px; ; margin:0px; -moz-margin:0px;-webkit-margin:0px;display:block;\">");
If the styles doen't get applied as expected it is a browser issue. The WebBrowser control emulates Internet Explorer in IE7 rendering mode by default. You will have to change some registry settings to change this behaviour. Please refer to the following
links for more information:
http://weblog.west-wind.com/posts/2011/May/21/Web-Browser-Control-Specifying-the-IE-Version
https://social.msdn.microsoft.com/Forums/vstudio/en-US/cf66e0cd-ab6f-45b8-b230-1d78f26670d2/opening-links-from-wpf-webbrowser-control-in-default-browser-instead-of-ie?forum=wpf
-moz-column-width only works in FireFox for example.
You may also navigate to an actual page and inject some javascript function that for example adds the styles to the body element dynamically or set the style properties of the body element directly:
private void Window_Loaded(object sender, RoutedEventArgs e)
MainBrowser.Navigate(@"E:/Epubs/ePub2_Sample05_Biology_SampleChapter_EN/OPS/ch01.xhtml");
MainBrowser.LoadCompleted += new LoadCompletedEventHandler(webb_DocumentCompleted);
private void webb_DocumentCompleted(object sender, NavigationEventArgs e)
WebBrowser webBrowser = (WebBrowser)sender;
dynamic doc = webBrowser.Document;
//int _scrollWidth = (int)webBrowser.InvokeScript("execScript");
//mshtml.HTMLDocument webDocument = (mshtml.HTMLDocument)webBrowser.Document;
mshtml.HTMLScriptElement script = (mshtml.HTMLScriptElement)doc.createElement("script");
script.setAttribute("type", "text/javascript");
script.innerHTML = "function doSomething(){ /* do something here... */ }";
//add script to the head
dynamic head = doc.getElementsByTagName("head")[0];
head.appendChild(script);
mshtml.HTMLBody body = (mshtml.HTMLBody)doc.getElementsByTagName("body")[0];
body.style.background = "yellow";
//set any body.style property here...
webBrowser.InvokeScript("doSomething");
That's about it as far as WPF is concerned.

Flex charts: How to hide axis lines with CSS?

Hello!
How do I hide my axis lines with CSS? Shouldn't this work?
<mx:Style>
@namespace mx "library://ns.adobe.com/flex/mx";
mx|ColumnChart {
    horizontalAxisStyleName: myAxisStyles;
    verticalAxisStyleName: myAxisStyles;
.myAxisStyles { showLine: false; }
</mx:Style>
I also tried display: none.
Prior to this I used:
<mx:horizontalAxisRenderers>
<mx:AxisRenderer showLine="false" axis="{someName.horizontalAxis}" />
</mx:horizontalAxisRenderers>
<mx:verticalAxisRenderers>
<mx:AxisRenderer showLine="false" axis="{someName.verticalAxis}" />
</mx:verticalAxisRenderers>
But it produced some annoying warnings:
Data binding will not be able to detect assignments to "horizontalAxis".
Data binding will not be able to detect assignments to "verticalAxis".
Thanks!
--Dwayne

Regarding the data binding warnings, see if you can get away without specifying the axis. Not sure if that will work. Otherwise, give the axis an id like the example at the bottom of http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/charts/AxisRenderer. html#axis.
The doco for showLine says "Specifies whether to display the axis. The default value is true." I think it's referring to the line at the bottom of the axis, next to the numbers. It's nothing to do with the grid lines. Which explains why your code doesn't work.
If you are not using gridlines at all (= not using the lines, not using horizontal-fill and horizontal-alternate-fill etc), then I think you can just get rid of them by specifying an empty array. Either in actionscript or in your chart tag (<mx:ColumnChart id="highlights" dataProvider="{results.result}" showDataTips="true">) add the argument: backgroundElements = "[]".
If this is not desireable, go to plan b:
You can control gridlines via css like this:
mx|GridLines {
    gridDirection: both; // horizontal or vertical also accepted, but not "none".
If you want none... well I've got some code where I do this:
(backgroundElements[0] as GridLines).setStyle("gridDirection", "horizontal");
// One of the arguments is the alpha, i.e. alpha=0 (translucent)
var stroke:SolidColorStroke = new SolidColorStroke(0, 0, 0);
(backgroundElements[0] as GridLines).setStyle("horizontalStroke", stroke);
... and that definitely works.

How set up alert Monitor with available to promise profile?!

Gurus,
I read a lot of notes about alert profile but I ´ve been in doubt.
I set the monitor alert in /sapapo/amon1:
- Selected alert type
- Selected some products and my allocation
- Assigned alert profile - defined the bucket
Check instruction:
- Activated "ATP Alert Act."
I vent seen any place to assign my alert profile in /sapapo/bop. Is it possible or necessary?
When I redetermine the alerts for my profile in /sapapo/amon1 any alerts are showed.
I don´t want to use macros to create alert.
I created a scenary to see an alert:
My scenary
Availability: 100
Order confirmed: 100
I changed my orders to 50.
Availability: 50
Order confirmed: 100
Execute alert monitor
Result: No warning
I´m glad for your attention...
Best Regards!

How can I load data with Scripts on *FDM* to a HFM target System????

Hi all!
I need help because I can´t find a good guide about scripting on FDM. The problem I have is the next one.
I have on mind to load my data with data load file in FDM to a HFM target system, but I would like to load an additional data using an event script, ie after validate. I would need any way to access to HFM system though FDM Scripts, is it possible??
If so, It would be wonderful to get a data from HFM with any Point of View, reachable from FDM Scripts in order to load or getting any data.
I´ve looking for a good guide about scripting in FDM but I couldn´t find any information about accessing data on HFM target system, does it really exist?
Thanks for help

Hi,
Take a look at the LOAD Action scripts of your adapter. This might give you an idea.
Theoretically it should be possible to load data in an additional load, but you need to be very careful. You don't want to corrupt any of the log and status information that is being stored during the load process. The audit trail is an important feature in many implementations. In this context it might not be a good idea to improve automation and risk compliance of your system.

Matt

private function addGraph():void {
// Create the chart object and set some
// basic properties.
myChart = new BarChart();
myChart.showDataTips = true;

use the percentWidth and percentHeight properties.

WPF application should communicate with endpoints

How WPF application should communicate with endpoints?

Hi ,
Thanks for posing!
Do you want to using WPF call endpoint in azure service? I suggest you could create a WCF service as web role or a worker role on azure project, and use your WPF application call WCF service. You could set the endpoint in WCF configuration and WPF configuration.
You could refer to this sample code:

How can I Reconcile all tables on multiples mappings with scripting????

I have OWB 9.2.0.2.8
I have to reconcile all tables and external tables on multiple mappings.
How can I do it with scripting language, please?
Thanks very much in advance!!!!

Good afternoon Claudio,
Should be something like this:
foreach mapName [OMBLIST MAPPINGS] {
puts "Checking $mapName"
foreach tabName [OMBRETRIEVE MAPPING '$mapName' GET TABLE OPERATORS] {
    puts "Reconciling $tabName"
    OMBRECONCILE TABLE '$tabName' \
      TO MAPPING '$mapName' \
      OPERATOR '$tabName' \
      USE (RECONCILE_STRATEGY 'REPLACE', MATCHING_STRATEGY 'MATCH_BY_OBJECT_ID');
}If you want to alter reconcile and/or matching strategy, check documentation on OMBRECONCILE in the OWB Scripting Reference.
Good luck, Patrick

Problem Running App with Scripting Bridge on MAC OS X TIger

Hi,
I have an application which link with Scripting Bridge Frame work, use XCODE 3.0 and SDK 10.5. I use Scripting Bridge, to control some functionality of ITune from Objective-C. This Application run fine on Leopard and behave as expected. When I Run this application on Tiger this does not load.
Considering that scripting Bridge was first released om Leopard.
Can my Above Application Run on Tiger. If not how do I interface ITune from Objective-C, on both Tiger and Leopard? IS there update which suppose to fix this?
Thanks

No.

There will be no update for old products like Tiger. What there is is all you will ever get. For Tiger, you will have to dig into sending Apple Events to iTunes manually. Or it might be easier to define your Apple Scripts as string resources in your application an execute them via a system() call.

How to sign a profile via Script

Hi,
i have managed an internal Website on which a User can log in with his Active Directory Account. The Site is looking for his phone number in the AD and an additional "AirTerminal" account for his phone number. If everything is ok, the User has the choice to select iPhone or Windows Mobile. After the choice he can push a button "Send Configuration".
The Configuration will be sent out to his phone with a SMS which includes a One-Time-URL. This One-Time-URL can, of course, be used only once, after that the URL will not work anymore.
The URL contains a File, specially for this particullary user, preconfigured with his E-Mail, Domain and Username. After the Profile is installed, the User is only be prompted to supply his Windows Password for Exchange.
This is working fine!!! We do not have any problems with this kind of deployment and the Users like it.
The only thing disturbing is the "Unsigned" showing up in the Profile. We would like to sign this Profile and really do not want to use the ICU or SCEP and so on. Our solution is completely independent of infrastructure. The solution can be used with any kind of LDAP. So no need fpr Microsoft AD and so on...
How can this be resolved with scripting like shell, bash, php or whatever...
Could be that there is one time, and we will be kick off Microsoft, or whatever...
Kind regards
Stefan

How to set a minimum width and height for a stage or scene?

Hello,
Does anyone how to set a minimum width and height for a stage or scene?
I tried listening for width/height property value changes and then adjust the width/height if necessary, but that causes unpleasant flickering of the window.
In JavaFX 2.1 beta SDK for Mac OS, the Stage class has setMinWidth() and setMinHeight() functions which work very well.
I'm wondering what's the equivalent way to do that when using the FX SDK for Windows.
Any help is appreciated!
Thanks.

I was wondering how to enforce a minimum stage size with JavaFX 2.0.3.The same flickering way you are currently doing it. See: http://javafx-jira.kenai.com/browse/RT-15200 "Need a way to set the minimum size of a window"

How to set specific height in JLabel but vary in width ...

Hi,
I want to set the height of JLabel to fix height but vary the width according to the content of the label...
How does I do that ??
JLabel lbl = new JLabel("Hello this is aman");
lbl.setPreferredSize(100,30);
If the the text is changed, the width will be truncated at 100 pixels... how do I change
that to height 30, but width change according to text ?
thank

Hi..
may be this works for you ---
since u want to adjust the width with the text size.. means that you will be taking an input from the user and then set it on the label.. so before setting the text on the label & width of label .. get the length of the text and set this length as the width parameter to method setPrefferedSize()..
ex:
// get the text from textbox
String userinp = textbox.getext();
JLabel lbl = new JLabel();
lbl.setPreferredSize(userinp.length,30);
lbl.setText(userinp);
