Executing a child class from parent.

Hi, well, I have this parent class which I need to execute a method from a child class to get a significant part of the thing get started. Is there anyway for me to accomplish this or a workabout? Thanks..

Sure.. I have this method in the class logic:
     public void createLocation() {
          try {
          classCoord coordSet = appinterface.decodeFile();
          int areaNum = coordSet.areaNum, cellNum = coordSet.cellNum, signalStrength = coordSet.signalStrength, receiverId = coordSet.receiverId;
          String dateTime = coordSet.dateTime, userName = coordSet.userName, location = calLocation(areaNum, cellNum);
          boolean validity=calValidity(signalStrength);
          classLocation locationObj = new classLocation(this.type, userName, receiverId, validity, location, dateTime);
          appinterface storeLocationObj = new appinterface();
          storeLocationObj.storeLocation(locationObj);
          catch (IOException ioException) {
               appinterface.displayMessage("Logic Error: " + ioException);
          catch (ClassNotFoundException classNotFoundException) {
               appinterface.displayMessage("Logic Error: " + classNotFoundException);
     }I need to execute this method halfway in the class appinterface, the logic class inherits from appinterface cuz I need to make use several methods from it. Is there any way to solve this somehow?

Fastest way to create child class from parent?

As the subject states, what do you folks find is fastest when creating child classes directly from the parent? (esp. when the parent is in a lvlib) I thought I'd post up and ask because the fastest way I've found to get working takes a few steps.
Any suggestions ae appreciatized!
-pat

Thanks for the quick response Ben!
Yea, I apologize, in your response I realize my OP was more than vague haha (it hapens when you get used to your own way of doing things I guess huh)- I'm trying to create a child from a parent so that it has all of the methods that the parent has.
In order to do so I currently have to open and close LV a few times during my current process so that vi's in memory dont get mixed up- Currently I save a copy of the parent class in a sub dir of where it is saved, close out of LV, open the new 'copy of parent.lvclass', save as>>rename 'child class.lvclass', close LV, and open up the project to 'add file', then right click>>properties>>inheritance.
Is this the only way to do this?
Thanks again!

p.s. I'm tempted to steal your cell phone sig, hope you dont mind haha good stuff!

How to listen to user actions in child class from parent class?

Hi,
I have a basic custom class ChildCustomForm that include a JTextField. In order to know what user types, I add a listener to
this textbox:
textField.addKeyListener( new KeyAdapter()
            @Override
            public void keyPressed( final KeyEvent e )
                //user typed something
                userTyped = true;
         });Now I have another parent class that uses ChildCustomForm, and parent class has to know once user types, then set
its own userTyped flag.
My problem is: since I added listener in child class, I cannot get textfield and add listener again in parent class, so parent class will not be able to know as soon as user types (polling is not a good solution here).
I am wondering if there is a way to do this?
regards,

I recommend that you look into a DocumentListener here so you will catch any changes, be they keyboard or cut or paste.

How to access objects in the Child Form from Parent form.

I have a requirement in which I have to first open a Child Form from a Parent Form. Then I want to access objects in the Child Form from Parent form. For example, I want to insert a record into a block present in Child Form by executing statements from a trigger present in Parent Form.
I cannot use object groups since I cannot write code into Child Form to first create object groups into Child Form.
I have tried to achieved it using the following (working of my testcase) :
1) Created two new Forms TESTFORM1.fmb (parent) and TESTFORM2.fmb (child).
2) Created a block named BLK1 manually in TESTFORM1.
3) Created two items in BLK1:
1.PJC1 which is a text item.
2.OPEN which is a push button.
4) Created a new block using data block wizard for a table EMPLOYEE_S1. Created items corresponding to all columns present in EMPLOYEE_S1 table.
5) In WHEN-NEW-FORM-INSTANCE trigger of TESTFORM1 set the first navigation block to BLK1. In BLK1 first navigable item is PJC1.
6) In WHEN-NEW-ITEM-INSTANCE of PJC1, code has been written to automatically execute the WHEN-BUTTON-PRESSED trigger for the "Open" button.
7) In WHEN-BUTTON-PRESSED trigger of OPEN item, TESTFORM2 is opened using the following statement :
open_form(‘TESTFORM2',no_activate,no_session,SHARE_LIBRARY_DATA);
Since its NO_ACTIVATE, the code flows without giving handle to TESTFORM2.
8) After invoking OPEN_FORM, a GO_FORM(‘TESTFORM2’) is now called to set the focus to TESTFORM2
PROBLEM AT HAND
===============
After Step 8, I notice that it passes the focus to TESTFORM2, and statements after go_form (in Parent Form trigger) doesnot executes.
I need go_form with no_activate, similar to open_form.
Edited by: harishgupt on Oct 12, 2008 11:32 PM

isn't it easier to find a solution without a second form? If you have a second window, then you can navigate and code whatever you want.
If you must use a second form, then you can handle this with WHEN-WINDOW-ACTIVATED and meta-data, which you have to store in global variables... ( I can give you hints if the one-form-solution is no option for you )

Calling a function in child window from parent window

Hi,
How can I call a method in child window from parent window in adobe air using javascript. In the following example I need to call mytest() function in
child.html from parent.html file.
Thanks,
ASM
//parent.html
<HTML><HEAD>
<script>
var initOptions = new air.NativeWindowInitOptions();
initOptions.type = air.NativeWindowType.NORMAL;
initOptions.systemChrome = air.NativeWindowSystemChrome.STANDARD;
var bounds = new air.Rectangle(300, 300, 600, 500);
var html2 = air.HTMLLoader.createRootWindow(false, initOptions, false, bounds);
var urlReq2 = new air.URLRequest("child.html");
html2.load(urlReq2);
html2.stage.nativeWindow.activate();
html2.window.mytest(); //NOT WORKING
</script>
</HEAD><body></body></HTML>
// child.html
<HTML><HEAD>
<script>
function mytest()
air.trace("in child window");
</script>
</HEAD> <body></body></HTML>

I suspect your problem is that the child window hasn't been created by the time you call the function in the parent.Loading the content is an asynchronous processes -- AIR doesn't stop executing your code until the window has finished loading child.html. So, you will need to add an eventlistener to html2 and call the function from there:
html2.addEventListener( "complete", onChildLoaded );
function onChildLoaded( event )
html2.window.mytest();

Spawning child program from parent concurrent program.

Hi All,
I am trying to spawn multiple child programs from Parent concurrent program, Parent concurrent program is having execution method as HOST.
Here is how I designed it.
1. Parent Concurrent program (Parent Conc program with execution method as HOST).
2. Host file is abc.prog calls PLSQL package xyz.main.
3. xyz.main has logic to launch multiple child programs - (Child Conc program with execution method as PLSQL stored proc) using fnd_request.submit_request utility.
All the child programs are getting launched but are in INACTIVE/NOMANAGER state. Could you please let me know how to overcome this issue.
Both Parent and child programs are added to standard concurrent manager. This issue is only coming when parent program as execution method as HOST if parent program execution method is PLSQL stored procedure then child programs are running fine..
I also tired initializing apps in HOST file (abc.prog) before calling PLSQL package xyz.main.
Thanks.
Sham.

hi,
even i was facing the same issue. while submitting the child requests through fnd_request.submit_request i tried the following:
FND_REQUEST.submit_request (
application => 'Application Short Name',
program => 'Program Executable Name',
description => 'Program Description',
start_time => NULL,
sub_request => FALSE,
argument1 => 'Input 1',
argument2 => 'Input 2' );
After this the Programs were submitted successfully.

How to create child part from Parent Item - BLOW UP Master - Automatically

Hi to All,
Have any one defined this process?
To create child part from Parent Item - BLOW UP Master - Automatically ie. we receive FG from customer which we need to blow up to its child part. In that case, FG should be consumed & child parts should be generated in stock.
We tried with recursive, but the stock of FG was again generating with recursive.
Ex. FG after receiving from customer in stock 1
Child parts (with offtake 1) X1, X2, X3 in stock zero.
After processing, FG stock should be zero & X1, X2, X3 = 1.
Regards
Nitin

Create a BOM for one of the "child" parts that has the "FG from customer" as a component and all the other child parts are negative quantity components (by products).
To make it simple have all the components backflushed and auto goods receipt the child in the BOM header. Create a production order, then process the confirmation (this will auto goods receipt the 1st child, consume by backflush the "FG from customer" and put the other child parts into stock as by products.
You will need to get your material prices correct first so that there is minimal variance in the production order.

Error running child packages from parent package - Error 0xC0011008

Hey...
I am running a parent SSIS package (running sp2, 9.0.3042) that calls several child packages.
On our development server, we now cannot run this because we get 1 or more of these errors:
"Error 0x80004003 while preparing to load the package. Invalid pointer . "
"Error 0xC0011008 while preparing to load the package. Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored. . "
It is not occuring on the same packages. It varies every time it is run.
I can run every one of the child packages individually, using the same login ID that the parent is executed under.
The parent package works fine on my local machine and other servers running the same version of SSIS. Just not on this server.
Does anyone have any ideas???
Thanks
BobP

How to get initial value of Child View from Parent View in ADF?

Hi,
I am typically from a Oracle forms background and new to ADF.
In ADF,how can I populate the initial value for a new record in child view from the parent view?
For example.. using standard Departments and Employees tables which has parent child relation ship.
If I want to create a new employee.. how do I get the initial value for department_id of my employee record(employee table) from departments table in ADF?
Thanks in advance
Vishnu

USer, please tell us your jdev version!
If you have setup the data model in a way that it reflects this relationship (should be automatic if you use the 'create business components from table' wizard) this is pretty easy.
To check this, open the application module and select the data model. On the right side you see departments view and under it indented the employees view. This indent shows you that the employees view is a child of the departments view. This is all you nee for the model layer.
In the UI you open the datacontrol and open the departments view. One node it the employees view (as child). Now, if you work on a department (e.g. you drag the department view onto a page and drop it as form), you can add a button to create a new child (employee) by opening the employee node in department and drag the createInsert operation onto the page and drop it as button.
Then create a new page and drop the employees view (the child from departments view) on to the page and drop it as form. This form will then display the new row for thew employee of hte department.
Last thing to do is to add anavigation case from the departments page to the employees page and select this on the CreateInsert button.
The form should have the DepartmentId pre-selected.

Remove Child Window from Parent using WIN API

Hello all,
I am using User32.dll to make a parent-child relationship between two VIs. I use SetParent function, and pass the handle of parent VI and child VI to this function. Now, after this relationship has been established, I want to remove the child window from the parent and use it as a independent VI using WIN API. Can anyone help me on this?
Thanks in advance!

Go to Solution.

You should be able to set a NULL handle to undo the parent-child relationship and make the child window again a normal top level window. Setting the desktop as parent is probably not the same as being a top level window.

Cleaning up child class on parent wire

I have a child class running on a parent wire. The parent class has a reference, and the child class has some additional references. I want to clean these up during shutdown. But, because it is a parent wire, I cannot call my child class's "destroy" method directly. Is the best way to handle this to have destroy.vi be dynamic dispatch, so it will call the child's destroy method via DD, and set "call parent method" to required? This way if the class is a child, it will dynamic dispatch the child's method, but force the programmer to also call the parent method? How have others handled this?

Yes. That's the whole point of DD.
Note that for cleaning up resources, the order of the cleanup might be important, so either write in such a way that it doesn't matter or document it so that the developer of the child class knows exactly when the parent destroy should be called.

Problems accessing child swf from parent class

First off: Hi. I'm new - to the forum and to Flash.
I'm currently writing a flash app that requests a XML feed
from a Java controller and loads child swfs into various parts of
the stage based on the settings/URL details received from the XML
feed.
Its nearly there and I've got my head round a couple of weird
things, but theres one thing left that I've found impossible to
solve. Once the loader class has loaded the swf, it can't access
its methods or set its variables and the child can't access the
parent either (or access the parent's variables full stop). From
what I've read this should be possible. Heres some of my code plus
pseudo code:
Note the Panel class is not linked to a symbol and uses
composition to act like a movie clip, rather than inheritance.
quote:
class Panel{
function Panel(owner:MovieClip, insName:String,
depth:Number){
initiates properties etc....
panelMovie = owner.createEmptyMovieClip(insName,depth);
listener.onLoadComplete = mx.utils.Delegate.create(this,
scheduleModule);
loader.addListener(listener);
loader.loadClip(moduleX.url, panelMovie);
function scheduleModule(){
trace(panelMovie.key);
trace(panelMove.keyTest());
panelMovie.key = "dave";
trace(panelMovie.key);
Child swf:
quote:
var key:String = "test";
As you can see I create an empty movieclip which I store a
reference to in this class under the field "panelMovie". I then use
this (instead of target_mc like you might do with an event handler)
to try to access the child swf. The output is:
trace(panelMovie.key); = "test" (Works fine)
trace(panelMove.keyTest()); = (Nothing returned)
panelMovie.key = "dave";
trace(panelMovie.key); = "test" (Previous line = no effect)
Is this something related to using a class? Really would be
preferentially to keep all code outside of the fla.
I've also tried a lot of different combinations of _root,
_parent and _levelx. None of which I truly understand.
Any help would be much appreciated! Plus any good tutorial
links on timeline and referring to objects in it!
(Couldn't find the code tag/button...)

>>trace(panelMove.keyTest()); = (Nothing returned)
You have panelMove here instead of panelMovie

Child inherit from parents

I am traversing down a tree and need to know how i can have the child inherit properties from a parent if its value is null;
version 10g
example
id, parent_id, type
1, null, A
2, 1, A
3, 2,null
4, null, B
5, 4, null
for ids 3 and 5 i would like the type to be inherited from the partent so id 3 would have type A and id 5 would have type B.

Invoking command prompt & executing a java class from one more java class

Hi,
I have a problem with my application. I need to develop an editor which compiles and interpretes java programmes. I am develoopping it in Java (Swing and pure Java). I have no problem in compiling a java programme from my editor. But while execuing if any body writes a programme which has console input the system hangs. I am using Runtime.exec() method to call command prompt of Win'2000. My editor is working fine for the programmes written without console input in my editor. I want the same type of input acceptance as JCreator / Vim editors accept.
How can i achieve this? Please give me some source code help for my requirement.

When you create a Process object from executing a command you can grab it's input and output streams. Using these, and a text area, you can create a "virtual terminal" for your user to work with their console programs. The rest is just details :)

Copy multiple dispatch vi to new child class

Hi, I have just started with LVOOP and while I'm pretty sure I have a good understanding of the overall theme, there is one problem I foresee if I continue.
Situation:
BoardType is parent of classes CC2600 and CC1300. Currently the child classes are just empty place holders.
Almost all the methods in the child classes will be of dynamic dispatch type (currently only one).
From what I understand a dynamic dispatch must be available in all child classes plus parent class in order to work as intended.
Problem:
If I would go forward and implementing LVOOP this would require approx 30 dynamic dispatch vis for each class. I can right click but for just these two children that's 60 + 30 vis I must create manually. I would much prefer just to create a template once and then just basically drag and drop 30+ new vis for each new class that is created.
Is there a way I can define a set of template dispatch vis in the parent BoardType and have them added to all the child classes?
I tried the save as copy, but the problem is that I still have to replace the connector pane to represent the new owning class.
If it helps here's a very basic block diagram of what's going to happen, just after Reset.vi there will be a lot of other dynamic dispatch vis.
Thanks in advance.
Michael

From the OP it sounded like you were literally just copying from the parent.
What I tend to do is finish one child class and then save a copy to a new name and change the internal data (if required) and DD vis (if required).
I do agree though that these kinds of operations could be hugely simplified using helper programs. Give the link provided by others a try.
