How to implement dynamic Strings

Hi everyone,
i have a problem i�ve no clue how to solve.
I have to create an array of Stringsbut i do not know the length of it. i tryes to find out if there is any method in java which allows me to do that, but i didn�t find it.
So if anyone could help me? Thanks a lot.
the code i�m using to get an idea is as follows:
public String [] GetEnabled(){
String[] cadena ;
for (int i = 0;i < mainLogical.getNumPoints();i++){
if ( (mainLogical.getPointEnabled(i) ){
//this is the line which does not work, at least as i�m looking for
cadena = cadena + mainLogical.getPointName(i);
return cadena;
Thanks

If you are using earlier Java version, you would declare your List like this:List cadena = new LinkedList();The add method allows you to add an element to the list:cadena.add(mainLogical.getPointName(i));As your List contains only Strings, you can get a String array out of it:String[] array = (String[])cadena.toArray(new String[0]);

How to Implement Dynamic Modification Rule for Material & multiple vendor Combination

Hi Team,
In dynamic modification rule for Material & vendor combination, i have maintained material & vendor in Inspection plan at Material Assignments
1.If i purchase same material from different vendors then how to implement ?

Hi Balaji,
I am not sure if i have followed your requirement.
What do you want to do with Vendor Z? Do you want to inspect each lot from Z?
If yes:
Then Create 2 Inspection plans with same Operations and Same MICs, In Material Assignment, mention Vendor as Z so that 1st inspection plan will only be for Vendor Z. Do not enter DMR in Header.
In 2nd inspection plan Enter DMR and do not mention any vendor so this plan will be applicable for all vendors except Z.
If No:
Then create Qm info record for vendor Z with "No inspection" set in QI06.
Amol.

How to implement Dynamic Context Node Mapping between Components

Hey genuis:
I am looking for how to implement context mapping bwteen two components. I read some threads, and try to use external context mapping. The example works fine. However, my requirement is more than that.
I have a context node in Component B, and the attributes in it are dynamically generated. Component A is the main component which use Component B's function. Both A and B work fine by theirselves.
When I assemble A and B (external mapping), the system gives me a exception:com.sap.tc.webdynpro.progmodel.context.ContextException: MappedNodeInfo(T8UploadCompInterface.data): cannot create nodes, no mapping defined yet.
Please give me some suggestion?
Any responses are appreciated.

How to implement Dynamic SQL in DataService ??

Hi,
Is there any way in ALDSP to implement Dynamic SQL in Dataservice ?
My scenario is "based on set of optional fields i need to join different tables.If the optional field is not there then i don't have to join with the corresponding table."
Thanks

Ah yes, I thought that looked familiar. It's same question from July 12.
There is no way to generate Dynamic SQL in DSP XQuery. There is one query plan for each query. The query plan does not change based on the inputs.
Using a FilterXQuery on top of a query actually generates a new query. You can play with that if you like, but it is not particularly suited to changing joins. Go with the ad hoc query.

How to implement Dynamic form validation

Hello,
I've been reading up on the forums about using the htmldb.item package to dynamically create form elements using a SQL query. Assuming I can generate the form dynamically, what approaches/options are available for implementing dynamic validation of the form elements themselves?
Thanks in advance

You could write a page-level 'PL/SQL Function Body returning error text' validation where you loop over your dynamic form elements (htmldb_application.g_fnn), check the values and raise errors as needed.

How to implement Dynamic Sort to an SQL classic report?

Hi,
I'm trying to implement dynamic sort to my working sql classic report, when user selects order by column from select item(action as submit page), the report should be refreshed and display with the selected column sort order.
But not able to do so.
Report Query:
Select a, b, c from sample order by :P1_ORDER_BY
P1_ORDER_BY - Select Item:
STATIC2: Column 1;a, Column 2;b, Column 3;c
Running page, report doesnt sorts in any of the column priority.
Kindly guide.
Regards,
Krishna

Of course the select item is in use.
It should submit the the page on select so you can retrieve the current value in you report select statement.
look here:
http://apex.oracle.com/pls/apex/f?p=21296:2:
table:
create table sample
a varchar2(30)
, b varchar2(30)
, c varchar2(30)
insert into sample values('a','z','k');
insert into sample values('b','y','d');
insert into sample values('c','x','a');
insert into sample values('d','w','b');
commit;
Select List:
P2_ORDER_BY
STATIC:Order by A;A,Order by B;B,Order by C;C
Report select:
select
a,b,c
from sample
order by
decode(:P2_ORDER_BY,'A',a,null)
, decode(:P2_ORDER_BY,'B',b,null)
, decode(:P2_ORDER_BY,'C',c,null)Marc

How to implement dynamic form?

Hi, all
Currently, I am using XPAAJ to merge xml data sent from Flex side and the pdf template in the server side which is designed by LiveCycle Designer.
But now my question is that my form is dynamic, like the rows of table. How could I implement such kind of functionality?
Thanks
Alan Ji

And actually, the exact requirement is that user should enter values in Flex pages and click "View as PDF", data will be sent back to merge with PDF template.
Under this situation, how could the form be dynamic?
Thanks for any help.

How to implement dynamic language change in all Components

Hi all,
I`m quite confused because i have app in wich i create Language object it is singleton made using abstract factory used for querying text to be shown in components. I has simple method:
public String getText(String fieldName) {}
Wich returns text. I have also config object to know what desired language i want to have on startup. But problem occurs when i want to set dynamic language change during app run so all containers gets its texts again using language object (which is another type now). Do You have some ideas ??
I thought about extending all JButtons,Frames,Labels etc... and adding method:
void setYourText(Language l) { this.setText(l.getText(// and here we have problem because all fields have unique arguments for getText
}

How to load dynamically String into a VI using LabVIEW Run-time Engine Version 7.0?

I would like to be able to traduce string into my application using import string method. I create an program with my VI to translate. When I use the import method, I get this error: the VI is locked. WHY ? because it works well in the edit mode but not using LabVIEW Run-time Engine Version 7.0 .

Hello loup,
If you call dynamically a VI in your LabVIEW application you must add this VI when you build the .exe file.
To add this VI, go to the Tab "Source Files" when you build application and click on "Add Dynamic VI..." then chose the VI you call.
It should solve your problem.
In the attached file you can found an example of LV program that translate front panel.
Try to build exe file and add "Languages.vi" as dynamic VI and .txt files as "Support files".
I test it, it works.
I hope that this will help you.

How to implement Dynamic properties files?

Hello,
I use Properties files to display some messages in my jsp but It could be very usefull if someone can tell me a way to reload my properties files when my application server is running.
Or if Someone can tell me where to find the singleton who manage the map of message it can help me a lot ^_^.
NB: I use Struts framework to manage properties, but if someone have a solution with JSTL I'm interest too.
best regards,
J�r�me

Hi Jerome, this is something all Java developers have run into at some point I believe. The ResourceBundle in Java reads your .properties file once and cannot be told to re-load. Unless you can do some sort of classloader trick, not sure.... You have a few options otherwise:
1) Write your own ResourceBundle which either checks a database or re-reads a .properties file on some timely basis.
2) Use Spring's ReloadableResourceBundleMessageSource (http://www.springframework.org/docs/api/org/springframework/context/support/ReloadableResourceBundleMessageSource.html) The only drawback here being you no longer use the ResourceBundle like you would a normal Java resource bundle (i.e. using ResourceBundle.getBundle()) you now use Spring's MessageSource interface to get at your properties.
Hope that helps

How to Implement Dynamic Tree structure in jsp

Hi,
Does any body help me to solve out my requirement??
I want to display all my folder contents (parent & childs) in windows explorer format, the root folder path will come from database.

There are many ways to achieve this. The simplest would be to use some existing tag library that renders a tree structure and feed it with the required data.

How to create dynamic connection string with variables using ssis.

Hello,
Can anyone let me know on how to create dynamic connection string with variables using ssis?
Any help would be appreciated.

Hi vinay9738,
According to your description, you want to connect multiple database from multiple servers using dynamic connection.
If in this case, we can create a Table in our local database (whatever DB we want) and load all the connection strings. We can use Execute SQL Task to query all the connection strings and store the result-set in a variable of object type in SSIS package.
Then use ForEach Loop container to shred the content of the object variable and iterate through each of the connection strings. And then Place an Execute SQL task inside ForEach Loop container with the SQL statements we have to run in all the DB instances.
For more details, please refer to the following blog:
http://sql-developers.blogspot.kr/2010/07/dynamic-database-connection-using-ssis.html
If there are any other questions, please feel free to let me know.
