Accessing function with a Class

Hi
I have a mp3player that I want to include in another flash
movie. The mp3player is a movie clip with an actionscript class
attached to it. I can use the mp3 player fine and it works
perfectly, but I have a slight problem when I want to change one of
the variables in the class. The class contains get and set methods
to change the playlist etc, and the only way I can think of to
access them is to create a new player object and call the functions
on that object. This kind of works- I can call the function and it
resets the playlist value, but for some reason the constructor in
the class is called straight afterwards and the playlist reverts
back to the default. I have a feeling this has something to do with
the fact that the actionscript class is attached to the player
movieclip, but I'm not an expert at using OO design in flash, and
so can't be certain.
I hope someone can help- I'm sorry I can't post any of the
code in the class, but it's a file I bought and the copyright won't
allow me to do so.
Thanks in advance

It's hard to attemp an answer when you don't supply any code.
Do you have access to the .fla file? What variables are are
involved? What are the instance names.? Are you working with the
.swf file?
If you are wrking with a .swf perhaps there is a LoadVariable
which is loading the play list from a text file which is probably
located in some folder under the SWFs root folder.on your system.
Check there and if so, let me know and I'll try to assist.

Private, protected Access Modifiers with a class

Why cant we use private and protected access modifiers with a class?
Thanks.

Public access allows you to extend a parent class in some other package. If you only want users to extend your class rather than instantiate it directly, make the class abstract and design for extension.Agreed. However, would the same argument be not true for the default access at the class level? No. Default access would only allow you to extend a parent class in the same package (as opposed to some other package).
Now my confusion is why is a class allowed default access at the top level and not protected?Because protected for a top-level class makes no sense. The protected keyword provides member access to any other class in the same package and extending classes outside the package. A top-level class isn't a member of a class, by definition, so there's nothing that protected would do provide differently than public.
So, the two access modifiers for a top-level class are public and default. Public allows access to the class outside the package, whereas default restricts access to the class within the package.

How to access function in extended class

I have a quick java question if you have the time to work it out - I've been doing some C# recently and wondered what the Java equivalent would be.
If I have a base class, that inherits another class, which also inherits another class, how do you access the monkey function in the cat class if I have a monkey function with the same name in the kennel class?
class cat {
void monkey() {
System.out.println("monkey in cat");
class kennel extends cat {
void monkey() {
System.out.println("monkey in kennel");
class test extends kennel {
test() {
monkey();
public static void main(String args[]) {
new test();

You can't. That's the way inheritance works.
If however you wish to call a method of the superclass in your class, use
super.methodName(arg1, arg2, ...);

How to access function from Top Class to Function of class that contain the the member variable of TopClass

Dear All,
is there any way that i can access function or member variable of aggregate class.

What problem?
The rules of C++ do not change because some of the code ins in a DLL. But the classes in a DLL need to be exported. See for example
https://msdn.microsoft.com/en-us/library/81h27t8c.aspx
You should also supply a macro so that the class header can be used in both the DLL and the client. See for example
http://stackoverflow.com/questions/14980649/macro-for-dllexport-dllimport-switch
If you exchange memory between the DLL and the client (as your example will do, because of the std::vector content), you should also be sure to use the same version of the compiler for each module, and to dynamically link to the CRT.
I would also advise you to start with a less complicated scenario, with just one DLL.

Physical Memory Access Functions with installed Security Update 5Q5FJ4QW

In my Labwindows-CVI (8.1.0) applications I use the Port-IO and Physical Memory Access Functions provided with the Utility Library to communicate directly to PCI devices. Up to now this works fine on about 50 different PCs using either only the CVI-Runtime or having different Labview or Labwindows versions installed.
Now I tried to install my software on a system with Labview 2011 installed. When starting my CVI-Program, it runs in a runtime-error and crashs. By searching in the Internet I found advices from NI about the Security Update 5Q5FJ4QW. In this paper NI wrote, that the functionallity of Physical Memory Access was eleminated with this update. The "UpdateValidator"-Software included in the NI paper showed me, that the appearence of this update is the reason for my software crash.
Here my questions:
Is it possible to do Physical Memory Accesses in another way, even on systems with the actual Labview or Labwindows runtime installed?
Is it possible to deactivate or deinstall the function of this update or the update (for example by replacing some files)?
How can I communicate directly from my CVI program to my PCI-hardware?
Thanks in advance for any hints to get my application running again
Willi

Hello Willi,
According to this Knowledgebase:
Inwieweit betrifft mich das Sicherheits-Update 5Q5FJ4QW von National Instruments (NI)? (German)
http://digital.ni.com/public.nsf/allkb/3D3631A092D3033C8625793600572C90?OpenDocument
The only way of running your Applications without Runtime Errors (With the Patch installed) is to run with Administrator Privileges.
So i guess it would be best to try this Solution and run your Application with Administrator Privileges and not to try to Workaround the Patch.
You should be able to eather uninstall the Patch by replacing cvintdrv.sys with the unpatched Version.
Normal Windows Patches can also be deinstalled by using System Control.
Best Regards!

Deny Access function with invalid file refnum causes LabVIEW to crash

Hi folks,
I have LabVIEW 8.5, and today encountered something interesting that consistently causes LabVIEW to crash. Essentially, if you find the "Deny Access" function under the advanced file IO palette and wire up an invalid refnum, Windows (XP in my case) reports that LabVIEW has to close. I checked in task manager, and the LabVIEW process is still active and using a disproportionate amount of the CPU.
To reproduce the issue, simply drop the function on your block diagram, create a constant from the refnum input terminal, and run the VI. Has anyone else seen this behavior?
Thanks,
Jim

Hi Carla,
I'm glad to help, and thanks for looking into it. The way I ran into the bug was while I was working on an action engine VI to log certain text values (see attached picture). While logging, I didn't want other programs to access the file. When a new file had to be generated, I wanted to stop denying access and close the reference. However, if the value on the shift register was invalid, LabVIEW crashed instead of throwing an error (I guess a crash qualifies as an error).
If you look at the attached picture, my workaround was to use the "Not A Number/Path/Refnum?" function. If the reference is bad, I don't try to use the "Deny Access" funtion or close the file. That worked just fine and seems like a good solution for now.

How do i create a static function in a class and implement ActionListener?

i am trying to create a pop up dialog box in a seperate class.

But how do i have a ActionListener ?
everything in a static function is static rite?

Call function, pass value, access variable in movieclip class from main stage

i am new to flash as.
I got quite confused on some problems. as the function here
is quite different from c and asp.net.
I have a movieClip named MC, and it's enabled with action
script, with the class name MC_Rectangle
and a Stage.
I override the MC_Rectangle class file in a mc_rectangle.as
external file.
here is the code:
package{
import flash.display.*;
import flash.events.*;
public class MC_Rectangle extends MovieClip {
var sequence:int = new int();
function setSequence(data:int):void{
sequence = data;
function addSequence():void{
sequence ++;
I have new a object in the main stage var
mc_rect:MC_Rectangle = new MC_Rectangle()
question:
in main stage:
1. how can i access the variable "sequence" in "mc_rect"
2. how can i pass parametre from main stage to mc_rect via
function setSequence(data:int)?
3. how can i call the function in addSequence() in mc_rect.
in asp.net, i usually use mc_rect.sequenct,
mc_rect.setSequence(data), mc_rect.addSequence() to achieve my
goals......
btw, can function in mc_rect return out result to main stage?
thanks in advance.

Your as-file must be named MC_Rectangle.as (same upper/lower
case as in the Class name)
Ad 1) You have to declare sequence as a public property
"public var sequence;" or - better - define a getter-function for
sequence.
Ad 2) mc_rect.setSequence(8); e. g. (you must write "public"
in the Class-declaration of setSequence)
Ad 3) mc_rect.addSequence(); e. g. (you must write "public"
in the Class-declaration of addSequence)
... and yes, your methods can return a value: Replace "void"
with the proper data type (int, String, ...) and place a "return
myNumber;" or the like in the method's body.

Help with SMTP class function with authentication

My server is no longer supporting the php mail() functionality. I need to use SMTP class function with authentication in my php code and they suggested this to replace it: http://www.yrhostsupport.com/index.php?/Knowledgebase/Article/View/101/2/smtp-class-functi on-with-authentication-in-php-code
So I tried it, but can't get it to work. This is my test form:
<form method="post" action="forms/sendmail-test2.php" onsubmit="return checkEmail(this);">
<script type="text/javascript" language="JavaScript">
</script>
<fieldset><legend>Info</legend>
<label> Name </label>
<input type="text"
name="name" size="30" maxlength="40"/><br />
<label> <span class="redText">*</span> Email </label>
    <input name="email" type="text" size="30" maxlength="40"/>
    <br />
<label><span class="redText">*</span> Message </label>
<textarea cols="40" rows="5" name="message" type="text" /></textarea><br />
    </fieldset>
<input type="reset" value="Reset" />
<input type=submit value="Submit Form" />
</fieldset>
</form>
This is sendmail-test2.php where the form goes. It won't send unless I comment out the first 10 lines.
<?php
include('Mail.php');
//$to = "[email protected]";
//$name = $_REQUEST['name'] ;
//$email = $_REQUEST['email'] ;
//$message = $_REQUEST['name'] ;
//$headers = "From: $email";
//$subject = " price quote";
//$fields = array();
//$fields{"name"} = "Name";
//$fields{"email"} = "Email";
//$fields{"message"} = "Message";
$recipients = '[email protected]'; //CHANGE
$headers['From']    = '[email protected]'; //CHANGE
$headers['To']      = '[email protected]'; //CHANGE
$headers['Subject'] = 'Test message';
$body = 'Test message';
// Define SMTP Parameters

$params['password'] = 'xxxxxx'; //CHANGE
/* The following option enables SMTP debugging and will print the SMTP
conversation to the page, it will only help with authentication issues. */
$params['debug'] = 'true';
// Create the mail object using the Mail::factory method
$mail_object =& Mail::factory('smtp', $params);
// Print the parameters you are using to the page
foreach ($params as $p){
      echo "$p<br />";
// Send the message
$mail_object->send($recipients, $headers, $body);
?>
It used to work fine when I used
$send = mail($to, $subject, $body, $headers);
$send2 = mail($from, $subject2, $autoreply, $headers2);
But they said I can't use it any more. I'm good with HTML and CSS but I don't know much about php. Thanks for any help integrating a from into this new code!

Thanks, bregent. I changed it to this and it sends, but nothing shows up in the body except "Test message". How would I "insert the form fields' 'email' and 'name' and 'message' in the body"?
<?php
include('Mail.php');
$to = "[email protected]";
$name = $_REQUEST['name'] ;
$email = $_REQUEST['email'] ;
$message = $_REQUEST['name'] ;

Access XI functionality with BAPI

Hello,
I'm new in XI theme. There two system: backend system at first and the XI. The problem is, that the backend system from the application need access to XI functionality with BAPI's. I not found for this. Can you get me a hint?
Thanks and best regards
Ritchie

Hi Ritchi,
in XI in Integration Directory, when you do a receiver determination, you can add multiple receivers and the condition on which reciever is to be selected.....so based on your condition in your source data, your target system will be selected.......
So you dont need BAPI for this case in XI.
Thanks,

__declspec (dllexport) CMyIShape* CreateShape()
// call the constructor of the actual implementation
CMyIShape * m_Obj = new ShapCircle();
// return the created function
return m_Obj;
in exe there is no include header of of ShapCircle and ShapRectangle
and from the exe i use LoadLibrary and GetProcAddress .
typedef CMyIShape* (*CREATE_OBJECT) ();
CMyIShape*xCls ;
//===================== from ShapeCircle.Dll
pReg= (CREATE_OBJECT)GetProcAddress (hInst ,"CreateShape");
xCls = pReg();
now xCls give all access of base class. but how to get pointer of funciton Fn_GetRadious() or how to get access.
thanks in advance.

could you please tell me in detail. why so. or any reference for it. i love to read.
i don't know this is bad way.. but how? i would like to know.
I indicated in the second sentence. Classes can be implemented differently by different compilers. For example, the alignment of member variables may differ. Also there is the pitfall that a class may be allocated within the DLL but deallocated in the client
code. But the allocation/deallocation algorithms may differ across different compilers, and certainly between DEBUG and RELEASE mode. This means that you must ensure that if the DLL is compiled in Visual Studio 2010 / Debug mode, that the client code is also
compiled in Visual Studio 2010 / Debug mode. Otherwise your program will be subject to mysterious crashes.
is there any other way to archive same goal?
Of course. DLL functionality should be exposed as a set of functions that accept and return POD data types. "POD" means "plain-ole-data" such as long, wchar_t*, bool, etc. Don't pass pointers to classes.
Obviously classes can be implemented within the DLL but they should be kept completely contained within the DLL. You might, for example, expose a function to allocate a class internally to the DLL and another function that can be called by the client code
to free the class. And of course you can define other functions that can be used by the client code to indirectly call the class's methods.
and why i need to give header file of ShapCircle and shapRectangle class, even i am not using in exe too. i though it is enough to give only MyIShape.h so with this any one can make new object.
Indeed you don't have to, if you only want to call the public properties and methods that are defined within MyIShape.h.
