Best way to implement placeholder graphic that is replaced later

Hi,
What is the best way to go about implementing the following functionality?
-User initiates to add a "placeholder" image to the timeline. As part of this process, the user is directed to a website to configure the image settings.
-At some time in the future, when the image has been generated on the website, get the image from the website and replace the placeholder image with the final image.
Is this something that could be accomplished through a plugin? Or is there another mechanism that is better?
Thanks
-Stevo

All JPA strategies require something (like a table or sequence object) be in the database, with table sequencing being the most portable, though EclipseLink does allow custom sequence stratgies where you could use something else, such as the UUID. Sequencing is described here described here http://wiki.eclipse.org/EclipseLink/Examples/JPA/PrimaryKey with a custom UUID example shown here http://wiki.eclipse.org/EclipseLink/Examples/JPA/CustomSequencing .

Best way to implement m to n relation?

Could you please give me some advice on the best way to implement m-n relations in apex?
Example: I want to store server and database info. A server can have multiple database of course. But in case of a RAC database, the database can be running on multiple servers. So I have tables:
create table SERVERS (id number primary key, name varchar2(30));
create table DATABASES(id number primary key, name varchar2(30))
and an m-to-n table
create table SERV_DB(serv_id number references SERVERS(id), db_id number references DATABASES(id), instance_name varchar2(30))
So the table SERV_DB can tell me e.g. that database PROD is running on server 'prdsrv1' with instance PROD1 and on server 'prdsrv2' with instance name PROD2
How would you design an apex page to maintain this information (adding relations, updating instance names, etc)? I have a solution using checkboxes and 2 for-loops over htmldb_application.g_f40 (to process checkboxes) and g_f41 (to process text fields with instance names) and some delete statements but the logic behind it looks too complex for me. I am convinced that this can be done more simpler. Seems like a common problem to me, so I wonder if there is no out-of-the-box solution in apex for this?
Could you please show me or create a small demo application with the solution that looks most elegant to you?
Thanks,
Geert

Thanks for your reply. You modified the question slightly, but conceptually it is still the same. What you call the instances table corresponds with my serv_db table. I understand the solution you propose using the tabular report. If I see it correctly, you would have an insert button above the tabular report for each new relation (instance - server) you would want to add. This is ok for the case i used (databases, servers, instances) because there are relatively few relations. However I would not like this solution for other cases. E.g.:
case: you have a list of persons and a list of tasks. You want to assign tasks to persons in a way that each person has multiple tasks to do and each task can be assigned to multiple persons.
Suppose you add a new person, and you want to assign 15 tasks to him. The solution above (with the tabular report) would be quite some work because you would have to click 15 times on the insert button and on each click select a task from the select list. In this case it would be more appropriate to, after selecting the new person, see a list of all tasks (e.g. 30 tasks) with a checkbox in front, so you can mark 15 out of the 30 checkboxes and press submit. It gets more complex when you want to assign also an attribute to the relation, i.e. showing the list with all tasks, a checkbox in front and a select list next to each task where you can choose from e.g. "priority high" or "priority low" to indicate that this task is high or low priority for that person. Is there an easy way to implement that?

Displaying Multiple Values on GUI components - best way to implement

Hi,
my program needs to implement a basic function that most commercial programs use very widely: If the program requires that a GUI component (say a JTextField) needs to display multiple values it either goes <blank> or say something more meaningfull like "multiple values". What is the best way of implementing it?
In particular:
My data is a class called "Student" that among other things has a field for the student name, like: protected String name; and the usual accessor methods (getName, setName) for it.
Assuming that the above data (i.e. Student objects) is stored in a ListModel and the user can select multiple "Students", if a JTextField is required to display the user selection (blank for multiple selections, or the student "name" for a single selection), what is the best (OO) way of implementing it? Is there any design pattern (best practice) for this basic piece of functionality? A crude way is to have the JTextField check and compare all the time the user selections one by one, but I'm sure there must be a more OO/better approach.
Any ideas much appreciated.
Kyri.

Ok, I will focus on building a solution on 12c.
right now I have used a USER_DATASTORE with a procedure to glue all the field together in one document.
This works fine for the search.
I have created a dummy table on which the index is created and also has an extra field which contains the key related to all the tables.
So, I have the following tables:
dummy_search
contracts
contract_ref
person_data
nac_data
and some other tables...
the current design is:
the index is on dummy_search.
When we update contracts table a trigger will update dummy_search.
same configuration for the other tables.
Now we see locking issues when having a lot of updates on these tables as the same time.
What is you advice for this situation?
Thanks,
Edward

Best way to implement app wide process

I am working on an application that has a list of art work in an sql report.. I want to be able to add each piece to a collection of items (which is stored in a table), so I added another column to the sql report to store the id of the art work. I am just wondering what is the best way to implement the process to insert the item to the collection of items. Since I want to do this from multiple pages - link from art work sql report; link from the edit page for a particular art work; and on the artists page where there is also an sql report, I thought it may be best to have an application process, to save duplicating the process on multiple pages.. however I don't think there's a way to pass the id of the item to the application process? as I was thinking best to have the application process conditional based on request, and then have the link as a doSubmit().
So is it best just to have the link redirect to the same page, passing the id of the item, and then having a process that runs before header that inserts the item, then assigning the item to NULL?
Thanks in advance,
Trent

Best way to implement this code in labview

Hi
What is the best way to implement this code in labview programming.
I have an analogue input which triggers a boolean light when it reaches a certain voltage. but at the same time i would like it to enable two other outputs one for a set period of time and the other stay on until another statement becomes true.
For example
case 1:
Set output high
Delay(2000ms)
Set output low
Case 2:
Set output high
If statement 2 is true
then set out put low
if not then repeat until statement is true
Thanks for your help

Hi David,
The code you posted will work, although note that the front panel becomes 'unresponsive' - as changes in the controls are only read once per iteration. The wait function is an example of an execution timing VI, however if we want to do software timing (like a 2 hour wait) - we should use software timing VIs.
Check out the following example (note we can stop execution during run-time):

Peter D

Best way to implement FREE purchase?

Hi,
I have purchases that are free for logged in users. What's the best way to implement a no-payment solution? Would having the payment fields hidden and COD auto-selected if the amount field is 0.00 a good idea? Is there a better way anyone has implemented this? And how about security flaws?

Hi
Here is an article about "no cost" orders

What is the best way to implement Carousel i.e. web part in a site page on office 365 site?

We can implement the Carousel web part in many ways like content By Query Web Part , jquery (nivo) plugin or content search web part etc. But among these which one is the best way to implement to get best performance of the page?
Thanks

content search web part always provides best performance because it uses the search. only consideration you need to take is, it does not display the changes immediately and you need to wait for the incremental crawl to happen.

Event Structures-best way to implement this UI?

I am trying to write a VI to control & read data from 4 different "channels" (each measuring a DUT) at once. I have written all the VI's for initializing instruments, communicating with the devices (VISA, GPIB), setting bias, reading data, etc...that has all completed. I just need to write the overall program with the user interface to allow the user to control these 4 channels & display the measured data.....as it turns out, this is the tricky part! My head is spinning from trying to figure out how to handle all the possible events.
Basically for each channel, I want the user to be able to
-enable/disable it for measurement (e.g. if there is no device loaded in Ch.3, we don't want to measure Ch.3..maybe disable/grey everything)
-set bias conditions (only if channel enabled). Allow user to change bias "in real-time" by increment/decrementing (e.g. incrementing from 5.00 V to 5.01 V, for example).
-turn biasing on/off (again, only if channel is enabled)
Also, I want each channel to display its measured data (e.g current, temperature reading)..every second or so. No graphs or anything fancy (for now! ), just numeric indicator.
Honestly, this all sounds so simple but I'm having trouble figuring out the best way to implement this, due to the fact that 1) there are multiple channels needing to be monitored for events 2) large number of user events that could occur (seems like at least 4 per channel - enabling/disabling, turning bias on/off, incrementing/decrementing bias values, etc ), Also the if a channel IS enabled, i want to be continously reading/displaying the data. What is the best way to handle this? Should i have 4 separate while loops, each with an event structure to handle events for that particular channel..or will that give me grief somewhre?
Also, I have another nagging question. Pretty much all the examples I see re: Event Structures and booleans involve latched booleans, eg. buttons that are just pressed once and pop back up...e.g. buttons you press to tell it to complete a task (e.g. "Acquire Data" or "Stop") , and once it's pressed it's over and reset. In my case, some of the booleans would not be latched...e.g. the "Enable Ch.2" button would be 'TRUE" as long as i want Ch. 2 to be read....does that make sense? Then, say hours later, if i did want to disable that channel, i would change it to "FALSE" and while that would be an "value change", the new value would not be "TRUE"..does that make sense? So not sure if that would be dealt with the same way in an Event Structure.
Hope this all makes sense and many thanks in advance for any help!!!

You're halfway there. I'd say the best solution is a producer/consumer structure, the event structure is used to generate queued commands to the consumer loop.
All data is handled in the consumer loop, where you among other things have an array of clusters of channel/instrument settings. (I usually have several cluster, one for test data, one for instrument settings, one for general settings and so on)
The event structure can have a 1 sec timeout, in which you queue up a Measure command.
In the consumer, in the measure state you loop through your instruments and if enabled you measure them and update their indicators.
The general (smart) way to setup the queue is with a cluster containing 2 elements, a typedef'd Command and a variant.
This way you can send data with the command in any form which is then interpreted in the consumer.
If, e.g. you press the Enable button on a channel, you can enqueue Enable and the channel number.

Best way to implement a simple read of multiple stings from a db

Hello guys,
I am trying to read a collection of countries (Strings) into a collection inside a Movie object. The countries reside in a separate DB table with a FK referencing the Movie.
My questions:
1) What is the best way to implement this? Do I need a seperate entity 'country' ? Is there a general way to read many strings into a collection?
2) the countries list does not have to be updated, only read. How do I make sure it is not persistent?
I have noticed that in my JPA implementation (in netbeans) I do not have something like CollectionOfElements (that is present in hybernate).
Thank you,
Marek

Best way to implement a standard layout across application

What is the best way to implement a standard layout across the application? For example, I am converting an HTML/ColdFusion site to Flex and I need to keep the look of the existing site in the new Flex app. I need a standard layout on every screen in the new app with a standard header, footer and left nav bar. Do I need to add that code to every screen in the app or can I just create on layout file and call that into every screen? Thanks!

There a few that will help you, look for Form and validator.

Best way to implement a docking container

Hi everyone,
I need to create a docking container that behaves the same way the draggable panel system works in Flex Builder (Eclipse):
- Dock other containers to the edges
- Automatically layout other containers when the dragged container is docked into/out of an edge
Is there a custom control that would enable me to do this? If not, what's the best approach to create one?

Thanks James.
I guess I can use the JSP Datagrid taglib as well.
My main purpose is to have the functionality of updating the cells, resetting cells, ability to perform aggregate of rows and columns.
Also, I have another table which will have rows that are an aggregate of all the rows in above datagrid.
Please let me know if you have any other ideas.

Best way to implement request-response and still reliability

          HI,
          what is the best way to implement a request -response paradigm and still have
          the reliability that message will be 100% processed and give response...do i need
          to create the permanant queues with storage..
          anybody gives suggestions..
          Akhil


Hi Akhil,
          Temporary destinations can only store non-persistent messages
          as per JMS spec - so they are not useful for reliable for holding
          responses that must survive longer than the life of the
          interested client. For persistence, you will need to use configured
          queues or durable subscriptions. For detailed
          discussion of request/response, I suggest reading the "WebLogic JMS
          Performance Guide" white-paper on dev2dev.bea.com. If you
          have many clients, or expect large message back-logs,
          there can be a performance impact when using selectors...
          FYI: There is a new pub/sub subscriber index enhancement
          that is available in 8.1 and
          in the latest service-packs for 6.1, 7.0.
          "Indexing Topic Subscriber Message Selectors To Optimize Performance"
          http://edocs.bea.com/wls/docs81/jms/implement.html#1294809
          This may be useful.
