NetConnection   .call() what is a parameter?

AS3
Hi, I'm trying to send variables to php 5 using the .call() but not sure how to send a variable, can anyone help?
from the manual:
myNetConnection.call(methodName, [resultObj, p1, ..., pN])
but I dont know what this part means. Can someone clarify? Can this be a variable?
p1, ..., pN Optional parameters that can be of any ActionScript type, including a reference to another ActionScript object. These parameters are passed to the methodName specified above when the method is executed on the remote application server.
thanks for any help..

I'm using AS3 to connect to a mySql database using Zend Amf. I was wondering how to send (post) variables to the database.
I found on www.gotoandlearn.com had us using the .call() to connect from AS3 to a php bootstrap that allowed us access to our db.
Sooo, in a long winded way I was trying to collect AS3 variables to be able to post to the db through Zend Amf.
I'd found some posts about using the extra parameters I just was getting errors in my php when I used them. So I thought I might be on the wrong path.

  • NetConnection.Call Parameter question

    passingArray=("a","b","c");
    NetConnection.Call (somephpfunction, responder,
    passingArray);
    Will I call method pass the array to the php function or will
    it pass the contents of the array as parameters to the php
    function?
    Meaning, am I to define the function as:
    function somephpfunction ($passingArray) {}
    or as:
    function somephpfunction ($a,$b) {}

  • Pass Class Object To FMS Using NetConnection.call Method

    Hello All,
    I have a custom class that defines several methods on itself
    to retrieve its data. This class object is then sent to FMS via the
    NetConnection.call method. Once received by FMS, FMS calls the
    remote method to dispaly the class object on connected clients
    (minus the originator).
    Now, standard properties are displayed correctly, but when I
    call the class method to retrieve the class data, no data is
    retrieved.
    My question is, can FMS handle class objects as parameters in
    a NetConnection call. If not, is there a better practice of
    applying methods to retrieve the class data? Example below...
    class com.QuizItem
    var numOfAnswers;
    var getAnswer;
    function QuizItem(question)
    this.numOfAnswers = 0;//<-- Returns correct number of
    answers
    this.getAnswer = function(answerNumberToGet)//<-- Does
    not return any data when called by client side script
    return this.answers[answerNumberToGet];//Already populated
    array
    Regards,
    Shack

    First, I know JAVA does not working "pass by
    reference". It's only working pass by value. (or call
    by value)But obviously you don't fully understand what it means.
    Isn't main_a and method_a alias?
    if there is not alias, why? please explain to me.No. They're two independent references coincidentally pointing to the same object. In your swap method, you move method_a to point to something else. This does not affect main_a.
    and why main_a.hashcode() is main_a's value?why not? What else should it be?
    I think It's mean copy object. but main_a and
    method_a, they have same object id! @_@;;;It means "copy reference", same object.

    I made a CF/Flex site based on the Flexstore sample app,
    using a database instead of XML as the data source; in case you
    want to see it:
    http://www.timos.com/dg/flex/DilemmaGames.html
    At first I had troubles similar to what you describe;
    initially, part of the problem was that my hosting company had not
    yet upgraded to CF 7.02. One other thing I had to correct: when you
    upload to your server, upload the entire ‘bin’ (or
    whatever your output folder is) minus the debug SWF.
    If it would help with other issues, contact me and I will be
    glad to make my project code available to you. Good luck.

  • NetConnection.Call.BadVersion - Channel disconnected

    I am facing NetConnection.Call.BadVersion error when I run flex based application with BlazeDS on S64 with Weblogic application server.
    At application start up, it makes 4 calls to server and get appropriate data. However once the application is up and hence forth I make any calls cause the error. I observed that the mid-tier java code (Remote Object) is not invoked by later flex calls. The faultDetails of FaultEvent says that “Channel disconnected before an acknowledgement was received”.
    I am not using HTTPS secured protocal.
    Has anybody face this kind of issues? Any input, suggestion or solution would be greatly appreciated.
    Other details are
    OS  : S64
    BlazdDS : Community Edition: 4.0.0.10620
    App. Server        : Weblogic 10.3.3
    The snippet of flashlog
    [DEBUG] mx.messaging.Channel 'my-amf' channel got status. (Object)#0
      code = "NetConnection.Call.BadVersion"
      description = ""
      details = ""

    FaultEvent.faultString :- Channel disconnected
    FaultEvent.faultDetail :- Channel disconnected before an acknowledgement was received
    Thanks
    --sachin

    I don't know what "S64" is, but it seems like someone is messing with the bytes of the AMF response so that the AMF deserializer in the Flash Player doesn't like the version header.  I assume you are running the latest player.  Probably need to check any network infrastructure and/or servlet filters.

  • Channel.Call.Failed NetConnection.Call.Failed: HTTP: Status 500 with amfphp php and mysql

    I have been scripting a simple database connection to check login credentials and am comming accross these errors:
    Channel.Call.Failed
    NetConnection.Call.Failed:
    HTTP: Status 500
    Any PHP code I run that is not connecting to MYSQL runs fine. But if I try to connect to the database thats what I get.
    Here is my mxml:

                                  <s:method name="getLogIn" result="onResult(event)" fault="faultHandler(event)"/>
    </s:RemoteObject>
    Which calls this actionscript:
    private function btn(event:Event):void
                                                 switch(event.target.id)
                                                           case "LogInSubmit":

                                                 Alert.show(errorMessage);
    and calls this PHP:
    If I comment out the database connection it returns a false value to me just fine but with it there it throws an error

  • NetConnection.Call.BadVersion :( :( :(

    Hey guys,
         I recently upgraded my development CF from 8 to 9, buy my production CF is still 8. Now I keep getting
              Channel.Connect.Failed error NetConnection.Call.BadVersion
         every time i launch my flex app on production server.  I assume this is becuase while compileing and building flex app my -services points to CF-9 services-config.xml.
             I tried to copy wwwroot/WEB-INF/flex folder into my flex application so that I have flex-cf8 and flex-cf9 folder in my flex app, and when I copy my build to production server. I change -services to flex-cf8/services-config.xml instead of flex-cf9/services-config.xml.  But this has not helped.
         My development server is a MacBook pro, while my development servers are MacPro and a linux system.  So the location of CF-HOME/wwwroot/WEB-INF/flex is different for both of my production servers.
         So my question is, is there a way to keep just one copy of services-config.xml in such a place where it will work for all my servers no matter what CF version is?  Will I need to make my own servies-config.xml file or can I just use the default one?  Does anyone have an example of custom services-config.xml (if I can't  use the default one).
    Thanks
    Jay

    After a bit more googling it turns out that NetConnection.Call.BadVersion might be a generic error, when flex can't communicate with/connect to flex2gateway.  Took a closer look at my code and turns out that I had forgotten about an update made that no longer accessed generic html file created by flex builder, but a modified version of it with some CF code.  Still not working hundered 100% but, this time I know whats and where things are wrong.
    Thanks

  • Differences between NetConnection.call() and RemoteObject

    I need to make a call from a Flash client to a server. I figured out that I can either make a remote call using NetConnection.call() or RemoteObject. Can anyone tell me what are the differences between the two? Is there another way to make remote call?

    Explain the purpose of the call? You could use xml.load() or even LoadVars() to make calls to servers.

  • Trying to understand what are the parameter/output From debug SNMP timers

    Hi All
    I am trying to understand what are the parameter/output
    From the debug SNMP timers
    Output SNMP timers :
    *Dec 31 11:56:27: SNMP: HC Timer 632DDE28 fired
    *Dec 31 11:56:27: SNMP: HC Timer 632DDE28 rearmed, delay = 5000
    *Dec 31 11:56:32: SNMP: HC Timer 632DDE28 fired
    *Dec 31 11:56:32: SNMP: HC Timer 632DDE28 rearmed, delay = 5000
    *Dec 31 11:56:37: SNMP: HC Timer 632DDE28 fired
    *Dec 31 11:56:37: SNMP: HC Timer 632DDE28 rearmed, delay = 5000

    *Dec 31 11:56:38: SNMP: HC Timer 70B54A70 rearmed, delay = 20000
    70B54A70 , 632DDE28 „² what this number means.
    5000 , 20000 „² why I have different delay time ( does it means that I have delay for SNMP request )

    The debug messages you are seeing are related to High-Capacity (HC) timers, which manage updates to 64-bit (HC) snmp counters as defined in RFC2233.
    The "fired" and "rearmed" messages indicate when each of these timers
    updates ("fired") the HC snmp counters, and when they should fire next
    (the "rearmed" messages). Higher speed interfaces require updates more often than lower speed interfaces, so you see two examples of that in your debug messages - 5000 ms updates vs 20000 ms update.
    The numbers that are in the messages (i.e. 632DDE28 ) are internal references to the timer that has fired.
    These messages do not indicate any delay in SNMP message processing, but normal SNMP operation of HC counters.

  • Flex4 Zend AMF error - NetConnection.Call.Failed: HTTP

    Somebody can help me? I don't realy have any idea how to solve this problem.
    P.S.
    I don't have services-config.xml file in my project cause the amf zend samples that I followed don't say to create it, somebody knows why flex 4 doesn't need it?

    The MessageBroker servlet is not installed properly. The context-root of the two Tomcat LC DS installs must be different. Test hitting the context-root Flex_App on both machines (http://hostIP:8080/Flex_App). If the context-root is valid you will hit the index.html page of the valid context-root which looks like this...

    You need to use a DataModifyQuery as your query does not return anything.
