Event on ClassFactory Object....inside a DataGridColumn

HI,
Follwing code used to create a textbox inside a
datagridcolumn.
This code working fine ...
var dgc:DataGridColumn=new DataGridColumn();
var factory:ClassFactory = new ClassFactory(TextInput);
factory.properties = {text: "TextInput"};
dgc.itemRenderer=factory;
Any idea how to add an event to that TextInput???
I wanna fire an onChange event on TextInput.. how to do it???
Thanx in Advance

If i understood right, you want to do some action in your
main application file when the TextInput (item renderer) throws
some event.
In order to achieve this. In your main application, add a
listener to the application object for the event thrown by your
custom component. In order to find out which object instance of the
custom component invoked the event, send some object with data to
identify the object instance in the event.
Hope this helps.

CREATE OBJECT inside INITIALIZATION event in ABAP

Hi everyone,
I have one question, can we create object inside INITIALIZATION event. Why, I am asking this question is, because most of the time I have seen people to create object inside start-of-selection. Please give your thought on this.
The code I have just coded below is also right or wrong?
CLASS lcl_build_data DEFINITION.
   PUBLIC SECTION.
     METHODS : constructor,
                        get_all_files,
                         validate_site.
*-- Private Section declaration
   PRIVATE SECTION.
         METHODS : clear_and_refresh,
                            display_output.
ENDCLASS.
*** class declaration, create instance for the class
DATA: gv_data     TYPE REF TO lcl_build_data.
INITIALIZATION.
*** Create class object. Constructor method will be called to Refresh
*** and Clear all internal tables and Work areas
   CREATE OBJECT gv_data.
*                    AT SELECTION-SCREEN             *
AT SELECTION-SCREEN ON s_vkbur.
*** Sales Office validation
   CALL METHOD gv_data->validate_site.
*                START-OF-SELECTION                    *
START-OF-SELECTION.
*** Get the list of all files from unix dir.
   CALL METHOD gv_data->get_all_files.

Since you are using the same object for your Selection screen related events, AT SELECTION-SCREEN, you would have to instantiate the object in the INITIALIZATION event. If your object usage is just for the data - In case you use the MVC design pattern, you should push back the object creation in START-OF-SELECTION.

How can I change the color of a object inside a symbol?

Hello!
I'm working on this study and I need to change the color of an object inside a symbol when I click another object.
The object is called "bola", wich is inside the symbol "ponto" and the clicking object are the colored pencils (each pencil should change the color of the symbol's object, giving the impression you'd selecting a different pencil to draw).
I think it's simple to understand what I mean when you see the files.
I already tried this line on click event of the pencils, but it didn't work:
sym.getSymbol("ponto").$("bola").css("color","#123456");
Anyone knows how to make that work?
I would like to improve the experience of drawing as well. I made it with the "mousedown" event. Is that a better way to get a similar effect?
My files
Thanks a lot,
Clayton F.

Ok here is another sample:
http://www.meschrene.puremadnessproductions.net/Samples/HELP/LapisB/Lapis.html
http://www.meschrene.puremadnessproductions.net/Samples/HELP/LapisB/Lapis.zip
You need to create a var that changes the css background color..
Hopefully you can understand what I did...
The text I left showing so that you could see it change...
I updated the files and all colors should work now.

Is it possible to access an object inside a Captivate movie from Javascript?

For example, my JavaScript performs some processing, based on which a particular button inside the movie needs to be hidden. Can I access a particular button from JavaScript to be able to do this? If not, then is it possible to be notified inside the Captivate movie, when a variable has been set by JavaScript? I notice that the JavaScript interface in Captivate 8 provides an event (CPAPI_VARIABLEVALUECHANGED) which fires when the value of a variable inside the Captivate movie changes. If there was a similar event which would fire inside the Captivate movie, when a variable changes then I could have set a variable using JavaScript and hidden a particular button using an advanced action, when the event for that variable changing fires inside the Captivate movie.
Articulate Storyline has an event which gets triggered when the value of a variable changes (either because of JavaScript executing or otherwise). If something similar was possible in Captivate, it would open up many possibilities.
I am evaluating Captivate 8.
Thanks in advance for any help.

Yes. its possible but its not recom
you can set in production system to allow changes to obj rsa1->transport connection->click 'object changeability', and look for object type , and set to changeable.

Cant do setColor(Color.BLACK); to a graphic object inside a class

i have a graphic object inside a class:
JPanel panel = new JPanel();
Graphic lienzo = areadibujo.getGraphic();
and then i cant do this:
lienzo.setColor(Color.BLACK);
netbeans error:
<identifier> expected
i just can do that inside a method from the class...

HI i found the problem.
The problem is that when i create the graphic object i do this:
Graphics lienzo = areadibujo.getGraphics();
areadibujo.getGraphics(); returns null so when i try to do something like lienzo.drawline(1,1,200,200); it just says nullpointer error, i guess at the time i create graphic object the panel "areadibujo" is not still created because the frame doesnt still shows, i can correct this by copying Graphics lienzo = areadibujo.getGraphics(); inside a actionperfmoded or other event method , but i dont wanna do that, where does the panel object already is created in constructor?.... i dont know if i explain my self well or how can i force areadibujo.getGraphics() to return something...

Events in Abap Objects

What are events. how to create and handle this events.

HI,
By triggering an event, an object or a class announces a change of state, or that a certain state has been achieved.Events link objects or classes more loosely than direct method calls do. Method calls establish precisely when and in which statement sequence the method is called. However, with events, the reaction of the object to the event is determined by the triggering of the event itself.
Events are most often used in GUI implementations.Other external object models, such as COM, ActiveX Controls etc, also provide events.
At the moment of implementation, a class defines its instance events (using the statement EVENTS) and static events (using the statement CLASS-EVENTS)
Classes or their instances that receive a message when an event is triggered at runtime and want to react to this event define event handler methods.
Statement : (CLASS-)METHODS | FOR ALL INSTANCES.
Every object that has defined events has an internal table: the handler table. All objects that have registered for events are entered in this table together with their event handler methods.Objects that have registered themselves for an event that is still live also remain live. The methods of these objects are called when the event is triggered, even if they can no longer be reached using main memory references.
If several objects have registered themselves for an event, then the sequence in which the event handler methods are called is not defined, that is, there is no guaranteed algorithm for the sequence in which the event handler methods are called.
If a new event handler is registered in an event handler method for an event that has just been triggered, then this event handler is added to the end of the sequence and is then also executed when its turn comes.
If an existing event handler is deregistered in an event handler method, then this handler is deleted from the event handler method sequence.
Events are also subject to the visibility concept and can therefore be either public, protected or private. Visibility establishes authorization for event handling :
     all users
     only users within that class or its subclasses
     only users in that class.
Event handler methods also have visibility characteristics. Event handler methods, however, can only have the same visibility or more restricted visibility than the events they refer to.
The visibility of event handler methods establishes authorization for SET-HANDLER statements: SET HANDLER statements can be made
     anywhere
     in that class and its subclasses
     only in that class

How to get attribute value from an object inside an object in Xpress

Does anyone know how to get an attribute value from an object in Xpress in a workflow? I have an object structured as follows:
<ResourceInfo accountId='mj628' tempId='3483372b787ce7dd:-5d99a0c5:130cb238483:-3600'>
<ObjectRef type='Resource' name='Google Apps'/>
</ResourceInfo>
I need if possible to get the name='Google Apps', which is inside the ObjectRef, so I guess its an attribute value of an object inside an object.

If the ResourceInfo object is accessible in a variable, i.e. named "myResInfo", you just have to check the Java API and call the relevant method:
<invoke name='getResourceName'>
<ref>myResInfo</ref>
</invoke>

How to get the values of the objects inside an object??

Hi,
I am trying to write code to display name and memory usage of all session attributes, in a recursive way.
I suppose reflection is needed here, but I cant figure out how to get the values of the objects inside an object...
private void handleIt(String attributeName, Object attributeValue) {
     boolean isPrimitiveOrNull = ((null == attributeValue) ||
          (attributeValue.getClass().isPrimitive()));
     if (isPrimitiveOrNull) {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "}");
     } else {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "{");
          Field[] fields = attributeValue.getClass().getDeclaredFields();
          int lim = fields.length;
          String name;
          Object value = null;
          for (int i = 0; i < lim; i++) {
               name = fields.getName();
               //LOOK AT THIS LINE: !!!!!!!!!!!!!!!!!!!!!!!!!!!
               value = fields[i].get(obj); //I don´t know what 'obj' should be??
               handleIt(name, value);
          sb.append("}");
Any suggestions will be greatly appreciated...

I realized that massive int objects called MAX_VALUE, MIN_VALUE and SIZE where causing the StackOverflow, so I removed them from the analysis.
This is the resultant code. But I think it isnt accurate in calculating the real size of objects being got using reflexion.
Do you or somebody have any more suggestions?

Multiple SQL task objects inside a package object is not generating proper DTSX

I am programmatically adding multiple ExecuteSQLtask objects inside a package. I am specifying all the required properties to the ExecuteSQLtask objects. However, when I save the package object to dtsx, the package looses the properties of some
of the ExecuteSQLtask object.
In the below example, I have created 3 ExecuteSQL task objects using the function AddSqlTask. However, once you run it, one of the objects will loose its properties. What makes it more weird is the fact that sometimes, object 1 looses the properties,
some times, its object number 2. Its random. I know that these objects are COM objects. Is there something I need to careful of when setting the properties ? Why are the values lost when I save them to DTSX ?

Why you do not tell what properties get lost?
And why is the same get repeated (you want parallel?):

package1.Executables[1] as TaskHost
package1.PrecedenceConstraints.Add(

And why not to add them
like

Event Bubbling Custom Object not inheriting from control

One of the new things flash flex and xaml have are ways which
the event easily bubbles up to a parent that knows how to handle
the event. Similar to exceptions travel up until someone catches
it.
My goal is to use the frameworks event system on custom
objects. My custom objects are:
ApplicationConfiguration
through composition contains:
SecurityCollection which contains many or no SecurityElements
and
FileSystemCollection.cs which contains many or no
FileSystemElement objects
ect ect basically defining the following xml file with custom
objects.
[code]
<ApplicationConfiguration>
<communication>
<hardwareinterface type="Ethernet">
<ethernet localipaddress="192.168.1.2" localport="5555"
remoteipaddress="192.168.1.1" remoteport="5555" />
<serial baudrate="115200" port="COM1" />
</hardwareinterface>
<timing type="InternalClock" />
</communication>
<filesystem>
<add id="location.scriptfiles" value="c:\\" />
<add id="location.logfiles" value="c:\\" />
<add id="location.configurationfiles" value="c:\\" />
</filesystem>
<security>
<add id="name1" value="secret1" />
<add id="name2" value="secret2" />
</security>
<logging EnableLogging="true"
LogApplicationExceptions="true" LogInvalidMessages="true"
CreateTranscript="true" />
</ApplicationConfiguration>
[/code]
basically these custom objects abstract the xml details of
accessing attributes, writing content out of the higher application
layers.
These custom objects hold the application configuration which
contains the users options. The gui application uses these
parameters across various windows forms, modal dialog boxes ect.
The gui has a modal dialog that allows the user to modify these
parameters during runtime.
basically i manage: load, store, new, edit, delete of these
configuration files using my custom objects.
Where would event propagation help in custom objects like
described above?
ConfigurationSingleton.getInstance().ApplicationConfiguration.CommunicationElement.Hardwar eInterfaceElement.EthernetElement.RemoteIPAddress
=
System.Net.IPAddress.Parse(this.textBoxRemoteEthernetIpAddress.Text);
The EthernetElement should propagate a changed event up to
the parent ApplicationConfiguration which would persist this to the
registry, db, file or whatever backend.
currently this logic is maintained else where. I serialize
the root node which compositely serializing the nested nodes and i
check of the serialization is different from that in the backend
… This tells me if the dom was modified. It works but i would
like an event driven system.
how should i implement bubbling using custom objects?
3 implementation ideas:
1) A simple way is to implement a singleton event manager:
EventManager.RegisterRoutedEvent
http://msdn2.microsoft.com/en-us/library/ms742806.aspx
I like this idea but how can you tell which object is nested
in who… this way the event can be stopped and discontinue
propagation?
2) If i use binders as discussed in Apress’s book:
Event-Based
Programming Taking Events to the Limit
basically a binder connects the events between seperate
objects together… although it would work for my app, I would
like a more generalized approach so i can reuse the event system on
future project.
3) how does flash flex handle this..
objectproxy.as?
http://www.gamejd.com/resource/apollo_alpha1_docs/apiReference/combined/mx/utils/ObjectPro xy.html#getComplexProperty()
>Provides a place for subclasses to override how a complex
property that needs to be either proxied or daisy chained for event
bubbling is managed.
how does these systems all work....? Reflection ?
this way i can simulate this on my own custom classes.
Thanks!

I have a strong sensation that the OSMF project is quite dead.
no new submits since 2010, the contact form on the offical OSMF
project website http://www.opensourcemediaframework.com/
returns a PHP error.
and many unanswered questions about OSMF in this forum.
i think it would be wise to not use OSMF if possible, although
I'm also stuck with it since we are utilizing HDS/PHDS
protocols which are utilized in the framework.
otherwise its quite a head-ache.
I'm unable to get to a video element coming from a proxied element
that is being produced via an HDS connection.
and haven't found any solution that works.

How to Use Sequence Object Inside User-defined Function In SQL Server

I'm trying to call sequence object inside SQL Server user-defined function. I used
Next Value for dbo.mySequence to call the next value for my sequence created. But I'm getting an error like below.
"NEXT VALUE FOR function is not allowed in check constraints, default objects, computed columns, views, user-defined functions, user-defined aggregates, user-defined table types, sub-queries, common table expressions, or derived tables."
Is there any standard way to call sequence inside a function?
I would really appreciate your response.
Thanks!

The NEXT
VALUE FOR function cannot be used for User Defined function. It's one of the limitation.

Why and how to use events in abap objects

Dear all,
Please explain me why and how to use events in abap objects with real time example
regards
pankaj giri

Hi Pankaj,
I will try to explain why to use events... How to use is a different topic.. which others have already answered...
This is same from your prev. post...
Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.

What is the equivalent for 'On Change of' Event in ABAP OBJECTS?

What is the equivalent for 'On Change of' Event in ABAP OBJECTS? and how to use it in LOOP control?

hi,
There is no such Equivalent in OO ABAP.
You have to Raise your own Event within tha class checking the value of the field whose value is changing.

Problem in reading an object inside another obj in C thru JNI

Hi All,
I am passing a java class object from Jave to C thru JNI.
This object has many integer fields + one object of another class, which also has some fields.
I am able to read integer fields from C but not able to read fields inside another object.
Can anyone plz help me in reading the object inside another object from C.
I m pasting class here for better understanding :
public class ImageMergeInformation {
public ImageInformation outputImageInfo;
public ImageInformation[] inputImageInfo = new ImageInformation[8];
public int topMargin;
public int bottomMargin;
I wanna read ImageInformation obj.
Plz help me...
Thanks in Advance,
Regards,
Sneha

You have to get the field id (getFieldID) of the variable you want, e.g. outputImageInfo, then get the object (getObjectField) in that field. At this point, you can start over (get the class, get the field id, get the object).

New object inside loop condition

I would like to create new object inside loop condition and use in its body
while(new File(localization).exists()){
//now would like use File object created above
}What's the notation for that?

}What's the notation for that?Encephalopathic gave it to you, but I'd worry about ending up with a never-ending loop. What about
if ((myFile = new File(fileString)).exists()) { ...instead?
Winston1) Same thing I put (except change the name "f" with "myFile")
2) you could get a never-ending loop with your answer (depending on the body)
3) The previous answer by Encephalopathic would NOT give a never-ending loop unless there was a never-ending listing of files with the name:
"Foo" + fileCounter + ".txt"; where "fileCounter" is incrementing (as done in his code)
