Is it possible to create a dynamic dispatch VI from parent VI as a template

Hi all,
I'm new to LVOOP and wondering if it's possible to create a dynamic dispatch VI from the parent VI as a template.
For example:
I've got a Class-method in the parent class. All child-classes use this method except of one child, which needs a little tweak on this VI.
So I need to overload the VI in the child class.
When I choose "New -> New Dynamic Dispatch VI" I get an VI based on a template
(As described by Darren Nattinger here: http://forums.ni.com/t5/LabVIEW/Darren-s-Weekly-Nugget-07-07-2010/m-p/1172483/highlight/true#M510414 )
Is it possible to get a copy of the parent VI instead that I can tweak ?
Thanks you in advance!
Best regards,
Balze

An over-ride VI is not that special.
The input and output classe must be "Dynamic".
The icon connectors have to be the same.
The Over-ride VI must have the same name as the parent and be a member of the child class.
So Save-as add to project but not to class.
Move to child class.
Rename.

Is it possible to create a dynamic(with a select) check constraint?

create table a (col_to_be_coded_fora number);
create table b (col_to_be_coded_forb number);
create table c (col_name varchar2(20), col_code number, col_desc varchar2(20));
insert into c values ('col_to_be_coded_fora', 1, 'active');
insert into c values ('col_to_be_coded_fora', 2, 'de-active');
insert into c values ('col_to_be_coded_fora', 3, 'pending');
insert into c values ('col_to_be_coded_forb', 10, 'school');
insert into c values ('col_to_be_coded_forb', 20, 'hospital');
insert into a values ( 1); -- meaning 'active' for table a, column col_to_be_coded_fora, can go in
insert into a values (10); -- meaning nothing for table a, column col_to_be_coded_fora, must give error
insert into b values ( 1); -- meaning nothing for table b, column col_to_be_coded_forb, must give error
insert into b values (10); -- meaning 'school' for table b, column col_to_be_coded_fora, can go in
I know i can handle this problem with dividing table c into to tables and creating foreign key relationship.
in this demo case i have only a and b, 2 tables but i want to encode thousands of tables with a table like c.
İs it possible to create a dynamic check constraint on a table which selects c table for the inputs that have permision?
Or do i have to use after insert, update triggers on table a and b to ensure this functionality?
Is there a smarter implementation for this need, may be a design change?
Thank you,
Kind regards.

Hi Tonguç,
A small design change makes it possible to do this with simple foreign key constraints.
I would do something like:
ual303@ORKDEV01> CREATE TABLE c (
2    col_name VARCHAR2(20),
3     col_code NUMBER,
4     col_desc VARCHAR2(20),

4     FOREIGN KEY (col_name, col_to_be_coded_fora) REFERENCES c

Is it possible to create controls dynamically.

Hai,
Is it possible to create control or arrays dynamically in LabVIEW.That means i want to create controls at run time depending on the dynamic data.
Please help me in this regard.

Creating a Dynamic Web Project from existing source?

I don't see this option in OEPE like there is in Workshop for Weblogic. All I can choose from is "Create Dynamic Web Project" which creates a new project from scratch, or "Create Java Project" which has an option in the wizard to import existing source.. however this makes it a vanilla Java project instead of a Dynamic web project.
Did the concept of importing existing code into a project not cross anyone's minds when this plugin was developed? It's as if the expectation was that everyone would use this on their own private projects and there would be no collaborative/parallel development.
What is the recommended way for creating a Dynamic Web project off of existing source code without stomping all over the existing web.xml weblogic.xml?

There are many "import" scenarios, so let's break them down and lay out the support expectations:
1. A java ee project created with base Eclipse using Web Tools Platform project types. This scenario includes both the case where the project creator had OEPE installed as well as the case where there was no OEPE installed. In this case, one should use the import existing projects wizard as the project being included already has metadata that can be read directly.
2. A java ee project created with a non-Eclipse IDE or perhaps completely by hand with rudimentary tools such as notepad. Currently, the way this case is supported is by creating new projects and copying application source into them. Advanced users may be able to configure support in place, but we cannot support users with this approach as the possibility of corruption is high. We are currently working on a set of wizards that will help automate this case. These wizards will be available in the release of OEPE that's slated to ship around the end of 2009 or early 2010.
3. A project created with BEA Workshop. This case is not supported as there are a number of technologies in Workshop that have been end-of-lifed (such as Apache Beehive). Users with Workshop applications should stay with Workshop until they are able to remove dependencies on end-of-lifed technologies. At that point moving to OEPE is recommended. Unofficially (this option is not supported but may work), advanced users may be able to migrate a Workshop app to OEPE, by stripping out all Workshop metadata (.project, .classpath, .settings, etc.) and by pretending that this is scenario #2 (import of a non-Eclipse application). Don't try this if your application still have dependencies on end-of-lifed technologies.

Help me to achieve my goal: creating a dynamic CQ5 website from a CRX Imported Site

Hello everyone.
For two weeks now, i'm trying to create a dynamic content CQ5 website from an imported CRX site.
What I already did and where I am now:
Step 1 - I have imported a website using the CRX Import Site tool.
Step 2 - I have done some mappings in my imported site images and texts. In the CRX content repository estructure, I can found the mappings as
unstructured nodes, at "etc/designs/mysite/dev/mappings", the component properties matching the components I selected in the component extractor;
Step 3 - I have done some extractions in my imported site images and texts. In the CRX content repository estructure, I can found the extracted components
at "apps/mysite/resources/images" (the last two ones I created myself);
Step 4 - After done all these steps, I acessed the Web Sites CQ5 menu and selected the "New Site" option, in the "New..." button. A "MySite Blueprint" is avaliable
to be selected as a Blue Print to my new site, but If I select this one and create my new site, not all the mapped components can be manipulated or selected and some
mappings just show on as an empty selection box in the page, where I am able to insert images, for exemple.
In short, after all these steps, I still can't do what I want with my mapped components and the new site is, basically, the same as the imported. Not every mapped components can be selected and edited and I can't change my site template or content (the far I got here is add a new image in the site, but without the liberty to change the position).
So, what I'm forgetting? Is there some step that I don't getting through? Maybe I need to work on the template created by the site importer?
Is there some material or media that can help me or maybe add knowledge to me?
Already read the "Site importer" and "Components" in Adobe CQ5 Documentation but don't get me far from where I am now.
If someone can help me to make this process better, with more liberty on my new site and the possibility to control all the components, adding new ones
or editing the existent ones, I'll be very gratefull and with a great new knowledge.
Operational System: Windows Server 2008
CQ Version: CQ 5.4.0.20110218
Thanks.

I want to do this using the site importer because I want to show my clients how we can make content management and experience customizations a lot easier starting by their own websites.
So, importing my customer website and transforming it in a new CQ website is the way to show this.
Anyway, thanks in advance and I'm going to look at the page component for the website that I imported.
If someone got another tip or hint, I'll be very thankfull.

Is it possible to create cube on t-code from R/3 ?

Hi,
there is one t-code in R/3 ZBDS.
Is it possible to create one simple basic cube with all the fileds this t-code shows and to load data in BW ?
Thanks,
KS

Hi Keral,
BDS - Business Document Service . You can search for a document that has been stored using the Business Document Service (BDS).
different tabs for Real estate objects, PM objects, Freight claims object etc. are different areas mainatined in the document finder . Customization is done here :- In the IMG , choose SAP Web Application Server -> Basis Services -> SAP ArchiveLink -> Document Finder Customizing ->Register Document Areas and Create Aggregated Document Areas.
Check this out fo rore information.
http://help.sap.com/erp2005_ehp_04/helpdata/EN/3e/8241421b35033be10000000a1550b0/frameset.htm
You say "In t-code there are different tabs for Real estate objects, PM objects, Freight claims object etc.
each tab has fields like business entity, object key, document type, created by, created on, changed by, change on etc. business want to create info cube on this fields.."
Do you want create reports on document finder?
Thanks

Is it possible to create a swatch or style from part of a pasted image?

Good Afternoon,
I'm one of the many (I'm sure) that "jumped right in without floaties" and I have stumped myself this morning. I have an image of my program that I have pasted into photoshop. I'd like to select a certain portion of that image (a titlebar, if you will) and create a swatch or style based off of that selection on the image, that I may then use later on for creating web pages. I have the Master Collection of CS4, so using one software over another shouldn't be an issue.
My initial searching hasn't turned up positive results. I'm hoping it's something really easy that I'm just overlooking. Thanks in advance for any replies.

No, not possible. What you are looking for is similar to symbols and those only exist in Illustrator and Flash. You can also designate such items as editable regions/ library items in Dreamweaver and Fireworks, so they can be reused over and over again. In PS, you will simply have to structure your document accordingly and adapt the content you add to your existing navigation/ mock program UI or whatever, not the other way around.

Re-clarify--Urgent -- Can Apex create a dynamic menu list from table?

Hi All,
I am asked to investigate the possibility of using APEX to create a table data driven drop down menu, which means the menu list is dynimically generated from what is in the table. Eg. if there are 3 rows in the table, then the application will generate 3 list, if I add a row, then user will see 4 lists next time when the page is refreshed.
Such menu list will need to be a home page, which means it is the first page to be called in the URL. If such function needs to be implemented in PL/SQL procedure, can the procedure be called in Apex's URL?
The deadline is tomorrow and I have spent quite a bit of time but still have not had any clue. Could any one have such experience to point me a way to focus on please? Many thanks.
Jennifer

Is it possible to create a PDF "print" button from InDesign behaviors?

In Acrobat, there is a way to create a button with a behavior for "print" that will queue the document up for printing. I don't see a way to do this on the InDesign end, though, via behaviors. Something that will export from InDesign and carry over to the PDF. As this is something I'd like to use on every page, adding it to a template would be much easier than manually adding these to each page in Acrobat post-export.
Any guidance anyone can offer would be greatly appreciated.

In Acrobat, Print is a button option, however, it only opens the Print dialog box, so the user can set choices and then print.

How can I create PDFs dynamically using data from a DB?

Hello,
I am using ATG Dynamo to serve up pages for a B2C medical eCommerce site. I would like the ability to create PDF copies of a customer's invoice starting with a generic PDF template, then populating the document with the invoice-specific data and serving it to the customer.
Anyone know where I should start?
Thanks,
Jeff

Two options.
1. Formated objects, which uses xml and xslt to create a pdf file. Apache has an open source FOP engine for Java. This is fairly complicated, but doable however the technology is relatively immature. Inexpensive, moderately steep learning curve given no prior experience.
2. Third party application, my company uses Document Sciences, j2ee solution. Expensive, small learning curve.

Is it possible to create a report combining data from 2 reports?

Post Author: swalker
CA Forum: General
We are upgrading the application, ServiceCenter. We have reports that show our Response and Resolution Metrics. I have 2 set of reports, one for the old version and one for the new version. I need to combine the results of both reports into 1 and do calculations on the data from both. Can this be done with 2 sub reports in the main report that does the calculations? Can 1 report connect to 2 separate databases? I am using Crystal Reports v8.5. Is there any documentation on this or sample reports? Can any one please give me some guidance? Thanks

Post Author: swalker
CA Forum: General
yangster thanks for the quick reply. I am not really sure about combining reports, so I looked into what you said. I tried to create a shared variable on the field that I need to share but that field is a running total and I get an error when I try to run the report "This field cannot be used becaus eit must be evaluated later." So I am not sure what to do now. Is there a work around for this? Thanks for any help.

Is it possible to create a CUP request initiated from the ECC backend?

Hello GRC experts,
I am hoping to solve a problem by interrogating the HR and SAP users tables in the ECC backend, and then in some cases, creating CUP provisioning requests to delimt specific user roles. I am not aware of any functionality that allows creation of requests other than HR triggers or manual data entry. (HR triggers do not satisfy our need as we are doing direct provisioning, so we must explicitly specify roles in the request. )
Has anyone done this before? Any ideas.
Thanks,
Yvonne Davis

Start with the test option in web service explorer to find out which items you need in the request.
Roles must still be imported in CUP. You'll need about the exact same configuration in CUP like for manual requests, the web service will basically just fill out the request form.

Creating a dynamicly sorted datatable from myfaces using request bean.

Hello.
Using MyFaces...
Has anyone got this working, all i get is a "Base is null" exeption when following the example sortTable.jsp from the myfaces source.
I use a BeanManager.prepareBeans(request) whom i call att the first line of the jsf file. The prepareBeans creates the beans and sets them using valuebindning, all beans are reqeust beans and should be so.
The created beans are displayed at the page with the sorting headercells rendered. When i hit the sorting header a exception occures, this can be fixed by using session beans but i dont want that.

Well i did not get this working and i am now creating my own custom component.

How to create/call dynamic XML feed from CFC - HELP PLEASE!!

Hey Dan....thanks for the prompt reply.
I added the wsdl and this is what I get when I call the service from this cfm page: http://www.prevu.tv/xyzTest.cfm
Have never seen output like this. Is this correct?
The web service I'm writing is also for some .net developers so it may be that I need to output as string also - this discussion has not taken place yet.
