Intermodule Communication in flex 3 using ExternalInterface

I have 2 modules, module A and module B, I want to use functions defined in Module B into module A.
How can I do this with ExternalInterface?

For local connection I will have to take instance of that module, which will unncessarily increase swf size
Consider a case of complex project wherein there are 100 modules passing data amongst each other.
Each module having number of functions
Wii it be a correct way to take instance of modules?
Instead writing a common JS file would resolve my problem, everytime I will have subscribe and publish messages on pagebus.Few lines of code (4-5) for intermodule every communication.No instance nothing.
Taking instance is the only approach for direct intermodule communication.

Error 2032 in communication between Flex Client and WCF

Hi All,
I'm trying to establish communication between Flex Client
and WCF service.
WCF service accepts gZip compressed data and returns gZip
compressed results.
So I used Flex ByteArray.compress() and
ByteArray.uncompress() for this purpose. However, it throws error
2032.
The gZip compression/decompression uses MemoryStream class in
C#. Based on my previous experience, memory stream communication
between Flex and C# gives erro 2032.
Is there a work around for this?
Thanks,
Vishal

I read some thread in the forum, and found somebody had the similar problem with me. Just want to know how to settle this problem.
In the client/server program. Client is a JAVA program and Server a
VC++ program. The connection works, and the problem appears after some time. The Client sends a lots of requests to Serverm, the server seems receive nothing. But at the same time, the server is able to send messages to Client. The Client also can get the messages and handle them. Don't understand why there this problem and why it appears when it wants.
The client is a Win2k platorm with JDK1.3.1 and the server is also a Win2K platform with VC++ 6.0.
In the Client, using:
inputFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
outputToServer = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
Hope can get your help.

How to pass a value to javascript from flash using externalinterface

hi,
i'm currently trying to call a javascript function and pass values to it. but i'm not really familiar in using the addcallback since i only tested on calling a function from flash without passing anything to the function.
Basically, i'm going to retrieve the values of a node from xml.
and then i will assign those values to a variable in flash.
now what i'm going to do next is pass this value to a javascript parameter..is it done using externalinterface?
Could anyone give me an example.
I just need to throw the value to the javascript function parameter and no return values to the actionscript.
The event is that whenever an image is click, the corresponding value for each image is passed to the javascript function.
here is my unfinished script.
function imageClicked(e:Event):void {
for each (var imageURL:XML in xml.images.link_to)
ExternalInterface.call("TestButton",imageURL);
thanks so much in advance.

first, it seems that the 'TestButton' funciton in JS will be called several times when an image is clicked - for each loop in the 'for each' loop you wrote.
second, in order to test the communication between AS and JS, try starting with something simple, like -
ExternalInterface.call('alert', 'OK');
if this doesn't work try tracing the ExteranlInterface.available property/
if it does work, place an alert within the 'TestButton' in the JS code, to see its actually being called.
and so forth...
good luck,
eRez

Resizing div height using ExternalInterface makes window jump in safari

I only notice this problem in safari, no other browser.
My application loads in modules as it needs them and changes the height of the HTML div that contains the movie, I do this using ExternalInterface.call. (This is because scrolling in flex/flash is downright awful, I like the scrollbar in the browser to work).
However, If I load in a module and inside of that module I change the external interfaces height, I find that the flash movie seems to jump down then jump back up about 150-200 pixels.
I want the movie to just stay anchored to the top of the div, no matter what the size of the div is. How can I enforce that policy on the player?
I have tried align: "t" and salign: "t" in the movies params, but I'm not exactly sure what that did as it still jumped down.

hey, thanks for the direction. I'm guessing that when i styled the attribute, any existing css style for the object still overrid the attribute styling.
Here is a simple version of my solution:
<code>
function autoWide (myID, minWide) {
var targetA = document.getElementById(myID);
var currWidth = self.innerWidth;
if (currWidth < minWide) {
targetA.style.width = minWide;
else {
targetA.style.width = '100%';
</code>
If anyone else is interested the innerwidth method doesn't work in all browsers, here is a link to an explaination.

Calling Webservice defined in SAP R/3 in Flex builder using mx:Webservice

Hi All,
I am calling R/3 webservices in Flex builder using <mx:webservice> tag. but the wsdl is not accepting additional parameters like &, = ....
when I try to run this code Flex builder is generating an error
<mx:WebService id="ws" wsdl="http://localhost.com:8088/sap/bc/srt/rfc/sap/Z_SIMPLE_TEST_WS?sap-client=030&wsdl=1.1"
 useProxy="false"
 result="handleResult(event)"
 fault="handleFault(event)" showBusyCursor="true" >
and when I remove the sap-client=030& and =1.1 from the wsdl, the program gets executed, however SAP is calling client 010 as that is the default client.
I would appreciate if anyone can tell how to pass the parameter sap-client=030 in Flex.
Thanks,
Madhavi

its because of the & sign. instead use it like below it will work.
Z_SIMPLE_TEST_WS?sap-client=030&emp;wsdl=1.1
in the above line replace 'e' in emp with 'a' (amp)

Issue with child items of flex tree using QTP

Hi,
We are trying to automate Flex web application using QTP10.
We are facing below issue with Flex tree when we try to automate a scenario of selecting a child item displayed in flex tree.
Issue:
On recording the step of selecting an item from Flex tree using QTP, the script displayed is .Select Index1. But when we replay it back no action is being performed.
Also on object spy we are able to navigate only till flex tree and we are not able to spy child items of flex tree.On the web page the child items are displayed as radio buttons/checkboxes.
Please provide a solution for me to this problem.
Thanks

Hi,
You could perform a HTTP trace (using HTTP watch) and compare the OCI data in POST method for both users (the correct and incorrect ones).
Perhaps there is some additional/missing information being passed from catalog to SRM.
Kind regards,
Ricardo

Flex session using blazeds?

Hello,
Need help on managing the Flex session using blazeds. If source is available, it would help a lot.

Hi saisri2k2,
Instead of making use of Server side session you can make a logic of your own at the client side itself by making use of the FlexEvent.IDLE and doing the appropriate action accordingly.
You can google for the FlexEvent.IDLE keyword. So if the user stays idle for a particular time you can register a check in the eventListener registerd for FlexEvent.IDLE and navigate or redirect user to another page.
Thanks,

AS 3.0 - using ExternalInterface.call to open a .pdf

Hi - using Flash - AS 3.0:
I am trying to use ExternalInterface.call to open a .pdf file - but it is not working - nothing is happening...
ExternalInterface.call ("window.open","diagrams/v1/crh.pdf", "WindowName", params);
but this line DOES work - call an .html file to open.
ExternalInterface.call ("window.open","m5_quiz/v1/quiz.html", "WindowName", params);
I can't find any information that says this should or shouldn't work - it seems to me it should open it.
To get around this - I have been using 'navigateToURL' to open the pdf file - but that triggers the pop-up blocker - using the External Interface call does not.
Any help/ideas?
Thanks,
Lisa

I agree - that code - if it opens an html should open a pdf - but it doesn't. And I don't know why..
Why is the code screwy? Could I do it better another way?
Thanks

Labview communication to Hart equipment using serial interface

I am trying to communicate with various Fluke / Hart temperature equipment (Chubb E4, 9107 Dry well..) with LabView 8.0 thru the serial interface. I have the list of commands from Hart but they are not the same as the typical serial write / read commands and are not working. I am communicating to other equipment using the serial interface with normal serial command formats (i.e. 001c000000FABD, etc... ) but Hart commands are single letters (i.e. t<CR> ) for reading the temperature. I'm not sure if the problem is with Hart or LabView VIs that I am using.
Thanks in advance

I'm sorry. I was the one who jumped to the conclusion that it was Hart protocol.
You are using in USB/RS-232 converter. I assume you see this as another Com port on your computer. I've used these devices before without problems, those a few people on the forums have said that certain brands just haven't worked for them.
As I said before, double check all the baud and parity settings. Double check that you have the right cable, whether it need to be null modem or a straight through cable.
The manual ftp://ftp.hartscientific.com/manuals/9105-07.pdf looks like it should be a null modem cable.
Check that you are actually sending out a CR character at the end of your string. Do you need to send a capital T or a lower case t. That actually messed me up for a few minutes recently on a device I was trying to communicate with. t<CR> should look like t\r if the constant you are writing is set to \codes display or 74 0D (lower case t) or 540D (upper case T).
Is the device set up to return a line feed in its response? Have you provide enough of a delay between the VISA write and read to give the instrument time to send the response?
Try things in hyperterminal. It is a simple place to start to see if you have basic communication there. If you do, then you can focus on the LabVIEW. If you don't, then you know the issue is with the wiring, device, or Windows driver or settings.
Are you using the basic LabVIEW VI's for Serial Read and Write or VI's that from somewhere else? You said "I'm wondering if LabView's VIs are feeding the newer information in the old format or something like that." LabVIEW is only going to send out whatever you tell it to send out.
Sorry it's a bunch of questions rather than answers, but hopefully it gets you looking in different areas that you may not have thought of.
