Naming Objects at runtime

Hi all!
I want to make instances of a class in a for loop then naming them for example something+i. so you would get somethig1, something2 and so on..
or even maybe naming them after a string provided by the user.
googlet it and found a previous posted thread where the replyes was that you couldnt do thi. I think it was missinterpiated a little. I know this is possible have seen it done at one time..
Any tips would be greatly apriciated :)

Well, I am making the new object at runtime. So why
shouldn it be possible to name it to?1) Objects do not have names.
2) Variable names are determined at compile time.
This is so because this is how the Java Language spec defines the language to work.

Identify objects at runtime

Is there a way to identify objects on a form at runtime other than items in blocks?
For instance, I want to identify frames on a canvas, boilerplate (text labels), tabbed canvases, etc. at runtime without actually naming them - as in getting the names/ids programatically through maybe get_canvas_property() or get_form_property.

You can use FIND_* built-ins for canvases and Windows - you can't address boilerplat objects at runtime.

How do I create multiple objects during runtime?

I don't know how to create multiple objects during runtime, here's my problem:
I get a String as input. Then I create an object called newobject. I put the object in a hashtable with the above string as key.
Then comes the problem, in order to create a new object, I have to rerun the same class, which uses the same name (newobject) to create a 2nd object. Now my hashtable doesn't reference to my 1st object anymore...
Is there anyway I can fill up the hashtable with different objects, and make each key point to each object it was supposed to?
For those who want to see a bit of the program:
public class PlayBalloon{
public Hashtable ht = new Hashtable();
for(){
Balloon pB = newBalloon;
newBalloon=new Balloon(pB);
ht.put("Some input from user", newBalloon);
for(){
ht.get(s).draw;<= s=string, draw=own meth. in Balloon
}

I think i can see the problem that you are having. You have, in effect, duplicate keys in your hashtable - ie, two strings used as keys with the same name.
The way that a hashtable works is as follows...
When you ask for a value that is mapped to a key it will go through the table and return the first occurence it finds of the key you asked for. It does this by using the equals() method of whatever object the key is (in your case it is a String).
If you cant use different Strings for your keys in your hashtable then i would consider writing an ObjectNameKey class which contains the String value that you are trying to put in the hashtable and an occurrence number/index or something to make it unique. Remember to override the equals method in your ObjectNameKey object or else the hash lookup will not work. For example
class ObjectNameKey {
    private String name;
    private int occurence;
    public ObjectNameKey(String name, int occ) {
        this.name = name;
        this.occurence = occ;
    public String getName() {
        return name;
    public String getOccur() {
        return occurence;
    public boolean equals(Object o) {
        if (!(o instanceof ObjectNameKey)) {
            return false;
        ObjectNameKey onk = (ObjectNameKey)o;
        if (onk.getName().equals(name) && onk.getOccur() == occurence) return true;
        return false;

How to create a text object at runtime?

Hi,
I am using crystal reports for visual studio 2010 and using c# to programming.
I need to create a text object in a specific section like section 2. and also I need to control the text object's position and text.
I tried to move a object like:
reportDocument1.ReportDefinition.Sections[j].ReportObjects<i>.Left = 0x8760;
but object's position doesn't change at all.
How can I do these (create a text object and change a object postion)?
Thanks

Hi Don,
Thank you.
I have downloaded a RAS ( report application Server ) sample.
The sample uses the Business Objects Enterprise XI release 2. I am using win 7 and crystal reports for vs2010. Can I use this version of crystal reports to create a text object at runtime? If not, what is the lowest version I have to purchase to achieve what I want?
Basicly I need following capabilities at runtime:
1) craete text objects, line objects, image objects.
2) change text object, line object and image object positions, sizes, values of text object. If can I like to be able to change font as well.
3) supress objects, sections.
4) change section's height

Custom Annotation :: inject object at runtime

I would like develop a custom annotation to inject object at runtime. The annotation will work as follows
1. develop ValidatorClass annotation on type.
2. If annotated on a type object will be created at runtime and injected to the object. e.g. in class A it will inject validatorimpl object to vald object/
Please let me know how to implement that.
package com.debopam.validate
public interface validator{
public String validate();
package com.debopam.validate
public class validatorimpl implements validator{
public String validate(){
   return "true";
pckage com.debopam
public class A{
@ValidatorClass(name="com.debopam.validate.validatorimpl")
validator vald;
}

yogeshd,
It might be that the .class file for the annotation that you are compiling against is the one you have given us the source code for above, but when you run the program, the class file for the annotation is not the same, and is one that was compiled before you added the static field.
This can happen if your classpath is wrong. (and would explain why the problem only occurs sometimes - because it is only failing when the classpath is wrong).
If you run the following program with the Fully qualified name of your annotation as the argument, and with the same classpath as you run your program, it can tell you where it is finding the annotation class file. Check that this is the same one that you are compiling to.
class WhereLoaded {
    public static void main(String[] args) {
        Class theClass=null;
        if(args.length > 0) {
            try {
                theClass=Class.forName(args[0]);
            } catch (Exception e) {
                e.printStackTrace();
                theClass=Object.class;
        } else {
            System.out.println(
                "The first argument should be a fully qualified class name," +
                " using java.lang.Object instead"
            theClass=Object.class;
        String name=theClass.getName();
        name=name.substring(name.lastIndexOf(".")+1) + ".class";
        System.out.println(name + " loaded from " + theClass.getResource(name));

Populating a authorisation object at runtime...

Hi,
how to populate a authorisation object at runtime? is it possible to have a variable etc that can be populated a runtime?
I have a object zsales_off which has different values for different users. i need to create separate roles just to have different values for sales office for different users. i would like to avoid this by having a single role with the zsales_off getting populated at runtime.
Details steps with code will be appreciated.
thank you.

Hello AHP,
i am not still very clear about the detailed steps to be carried out as i am a novice in abap.
i have created the authorisation variable and am using it in the query. if i manually assign values for sales office in the role, it is working fine.
i want to assign values at run time. i am confused with the process as such.
few doubts like:
1> the variable should be of "authorisation" processing type or "customer exit" processing type.
2>what to use I_step=0 or I_step =1? how to use? where to use?
3>to write a abap code or use a func module, which one? how to use.
any example(like in my case different sales office values for diffrent users) with DETAILED STEPS & CODE would be appreciated.
also i need to have multiple single values for each user(but not interval).
Please help.

RE: multiple named objects with the same name andinterface

David,
First I will start by saying that this can be done by using named anchored
objects and registering them yourself in the name service. There is
documentation on how to do this. And by default you will get most of the
behavior you desire. When you do a lookup in the name service (BindObject
method) it will first look in the local partition and see if there is a
local copy and give you that copy. By anchoring the object and manually
registering it in the name service you are programmatically creating your
own SO without defining it as such in the development environment. BTW in
response to your item number 1. This should be the case there as well. If
your "mobile" object is in the same partition where the service object he is
calling resides, you should get a handle to the local instance of the
service object.
Here is the catch, if you make a bind object call and there is no local copy
you will get a handle to a remote copy but you can not be sure which one!
It end ups as more or less a random selection. Off the top of my head and
without going to the doc, I am pretty sure that when you register an
anchored object you can not limit it's visibility to "User".

Subject: multiple named objects with the same name and interface
All,
More than once, I have wished that Forte allowed you to place named
objects with the same name in more than one partition. There are two
situations in which this seems desirable:
1) Objects that are not distributed, but are mobile (passed by value to
remote objects), cannot safely reference a Service Object unless it has
environment visibility, but this forces the overhead of a remote method
call when it might not otherwise be necessary. If it were possible to
place a copy of the same Service Object (with user visibility) in each
partition, the overhead of a remote method call could be avoided. This
would only be useful for a service object whose state could be safely
replicated.
2) My second scenario also involves mobile objects referencing a Service
Object, but this time I would like the behavior of the called Service
Object to differ with the partition from which it is called.
This could be accomplished by placing Service Objects with the same name
and the same interface in each partition, but varying the implementation
with the partition.
Does anyone have any thoughts about why this would be a good thing or a
bad thing?

Creating and compiling JavaFX objects at runtime

I am interested in the possibility of creating JavaFX objects at runtime where their definition is not know until runtime and am unsure about how to do this. Clearly I will need the JavaFX Script compiler at runtime which I guess is not that much of a problem but I am looking to accomplish this within the browser context so it would mean that I need the compiler to be available as part of the standard JRE much in the same way as the JavaFX Script interpreter is to obviate the need for it to be downloaded.
Does anyone know if the JavaFX Script compiler is available as a built-in component within the latest versions of the JRE? If not, is it planned to include it in the future (JSE 7 perhaps)?
Thanks,
The Gibbon

Perhaps the thread [Dynamic Scripting, how?|http://forums.sun.com/thread.jspa?threadID=5379268] can help.

4800 Can't find the named object

Hi people,
Does anyone know the cause of this message we're getting during a sync.
The messages page says The named object cannot be found in the directory. What does named object and directory mean in this context ie does directory refer to the filesystem (and maybe named object is a db file ????) or is it a synonym for data dictionary (and named object is a db object ???)
Thanks in advance.

Creating View Objects at Runtime for Validation

In Oracle® Application Development Framework
Developer’s Guide For Forms/4GL Developers tutorial there is a topic about Creating View Objects at Runtime for Validation.
Is there any sample code available for this topic?
Please help
Regards
S Karar

I have created a helper method . The code is given below
protected ViewObject getValidationVO(String viewObjectDefName) {
// Create a new name for the VO instance being used for validation
String name = "Validation_" + viewObjectDefName.replace('.', '_');
// Try to see if an instance of this name already exists
ViewObject vo = getDBTransaction().getRootApplicationModule().findViewObject(name);
// If it doesn't already exist, create it using the definition name
if (vo == null) {
vo = getDBTransaction().getRootApplicationModule().createViewObject(name,viewObjectDefName);
return vo;
// Validation_bc4j_project of type ApplicationModule not found
and created a validation method.
The code inside validation method is given below.
public boolean validateAvgMr(Number data) {
String batch_catg = getQuality();
// Get the view object instance for validation
ViewObject vo = getValidationVO("bc4j_project.v_sqc0150");
if (getTestStage()=="DOLLOP" && getQuality()=="DECO")
// Set it's bind variables (which it will typically have!)
vo.setNamedWhereClauseParam("batch_catg","DECO");
vo.executeQuery();
Number dol_mr_lcl=(Number)vo.first().getAttribute("DolMrLclStd");
setStdMrLcl(dol_mr_lcl);
return true;
return true;
I have checked the validation view and it is returing value with the same bind variable value but is not returning any value when using inside this method validation.
I have checked several times but can't find the fault in the code.
Please help

Modify object in runtime.

Ok, I wonder, since there is no simulation loop or anything, how do I modify an object in runtime. For instance, I want an object to check a variable for the color of the object. I also made a grid/surface with different y-values in the coordinates with lineArray, and would like to update the surface in runtime. How is this done, with behavious or something else?
Thanks in advance.

Yes, you use the Behavior framework for that. You can select different stimuli to activate a Behavior (elapsed time, number of rendered frames, user input, ...).
PS: There is a simulation loop, but it's not under user control. But the Behavior framework interacts with it.

How could I know the kind of an object in runtime ???

Hi,
Is there any way in order that I can to know the kind of a control (xfa object) in runtime (using JavaScript)?.
What's the attribute for that?
For example:
Drop-Down List :
choiceList
Text-Field :
textEdit
Check or Radio-Button :
checkButton
Thank you in advance!
