It sounds like you should probabally use RMI.That is, remote method invocation...these guys are doing a more complicated version of what you want to do:

Be sure to check out Sun's RMI tutorial:

Happy coding! Sounds like a fun little project...I want to do some RMI sometime when I get a chance...

I'm using pages 5.2 and feeling completely stupid by not knowing how to link two text pages together. Can anyone help? please...

Hi there, I'm trying to use pages 5.2 for the first time and I cannot find how to connect two consecutive pages together as I use to do with earlier versions of Pages... Any help?

Word Processing templates have what is called a Document Body.
That is the area defined by the margins and holds a default text area which flows from page to page.
Examples of WP templates are the Letters, Reports, CVs etc.
Layout templates have that switched off and require you to add Textboxes or Shapes into which you can type text. Each page is an individual Section and no text flows from page to page.
Examples of Layout templates are the Brochures, Business Cards, Posters, Newsletters etc
In Pages '09 you can manually link Textboxes to flow in your own set order and across pages. Pages 5 has dropped this along with 100 other features.

Linking two video clips together

I cannot find the way, how to link two video clips together so, that when moving one, the linked clip follows.
Is there a way of doing that?
The manual gives nothing with words: "linking video clips".
Message was edited by: TRST

You can't link video clips to each other. You can nest them. Put the two clips in a sequence the way you want them. Put the sequence with the two clips inside your master sequence. They will act as a single clip. That's the only way.

OBIEE: Link Two Separate Queries Together

Hi,
I am trying to link two separate queries together in BIEE.
I have a query that will give me the sales value in January 2012 (monthly query)
But I would need to use the sales value of January 2012 to help derive the weekly sales value in another query (weekly query).
How would you link up two queries together?
I tried using union but it doesnt seem to be working.
Thanks.
Bill

Hi Billy,
Sure, My pleasure. Here are the basic steps what you could go through.
1. Create an analysis with your Month (January) and Sales.
2. Save this analysis as Report1.
3. Create another analysis with Week and Sales.
4. Create a filter on column:Sales using the option 'Based on Another Analysis'. The analysis editor will provide you an option to browse your other analysis which you want this analysis to be based on and just click on this browse button, and navigate to and select Report1.
5. Once you have selected Report 1 through browse option, you get down in the same pop-up the relationship and use values in column.
So sample entries in this pop-up might look like
Column : Sales
Operator : is based on results of another analysis
Saved Analysis : /My Folder/Report1
Relationship : is equal than
Use values in Column : Sales
6. If you run this analysis, you could get all weekly sales figures which are equal to the january sales figures.
Hope this helps.
Thank you,
Dhar

How to avoid long user interface response time in long measurements ?

Hi
I tried to find more information regarding techniques how to avoid long user interface response times in case of extremely long measurement times with an external instrument communicating over GPIB, so I post this hoping to get some hint or a link to a guideline. I guess this is quite normal problem.
Problem is that when I want to measure long time in order to get an average result from the instrument, I have to wait until the result is returned from the instrument. Obviously that makes the user interface response very slow in traditional technique.
My restriction is the old GPIB 488 instrument driver that I would not want to modify, but I have source code to it.
What would be the best way to improve the response time for user interface ? I have looked into the few things:
* multithreading
* callback in main program for GPIB events
* modifying instrument driver e.g. to support VISA and creating a VISA callback
regards,
Petri

Several ways to do this:
If you're getting several measurements, you could have the instrument generate an asynchronous interrupt (an "SRQ" in GPIB terms), then collect the data in response to the SRQ callback. While you're waiting for the SRQ's, you can have your main thread running the interface so responsive GUI. You don't have to spinlock on the GPIB read waiting for instrument data.
Or, as you mentioned, you could spawn a thread to manage the measurements, and use a timer in the main thread to periodically allow you to check the status of the measurement thread. Again, the main thread mostly just runs the user interface.
Either way, the idea is to keep the main thread freed up most of the time to run the GUI, and have it periodically check for completion of your measurement sequence. While you're waiting in the main thread, you may want to make sure the user can't inadvertently re-trigger another measurement sequence until the active one is complete.
If you do find yourself doing a dead wait, you'd want to break this up into a series of shorter waits, and in between each wait, do a ProcessSystemEvents from the main thread to keep the GUI active.

How to link two combo boxes? (urgent)

Hello,
I am wondering how to link two combo boxes in Acrobat Pro 9. Basically, I need to link a building with a list of rooms. There are 3 building choices in my first combo box. For the sake of example, Building A, Building B and Building C. When one of the buildings is selected, I want a 2nd combo box to display the rooms that are located in that building. So by selecting building A, you would then be able to choose a room from the list of available rooms in the second drop box. The buildings cannot share a list of rooms because they have the same room numbers. Is anyone able to help?
- Travis

You can also use ajax. When the first combo box element is selected, it will call the ajax function and that ajax function will bring the data from the database and place it in second combo box.

Two users (on the same Mac) using same RAID simultaneously?

O.K. I know you should never never ever connect two different Macs to the same RAID unless using Xsan. . .
How about connecting two users on the same Mac simultaneously?
In other words, can I have one user manipulating data on the RAID in the background while reading the data using a second user (on the same Mac)?
Thanks,
Ed

That depends on the application in question.
Since all the data requests are coming from the same Mac, you don't have the issues you would have if you had two different machines talking at the same time.
However, it now depends on whether the application(s) you're using supports file locks.
As long as the application that's manipulating the data properly locks the part of the file it's working on, and that the application you're using to read the file reads the locks and knows whether or not it's OK to use that part of the file, you should be OK.

How can I set up a wi-fi network, using one time capsule and two airport express

how can I set up a wi-fi network, using one time capsule and two airport express ?
The time capsule is near the Mac. ok
The first Airport is on the corridor, ok, works well and the App on the iPad signals so, ok
But when I plug the next Airport on another room nearby nothing happens, and signals disconected ....
is the signal so weak that is not able to go to ono room to the other ?

Well, even if you have the first express set up to extend the network, the second express can only extend from the TimeCapsule.
Maybe you got walls of sheetrook in the way, or kitchen/bathroom tiles, etc, dampening the signal rapidly.

I am facing problem regarding graphical user interface. I am using text box for editing files. I want to show the line numbers and graphical breakpoints along with text box. Can anybody help me in this? Thanks.

I am facing problem regarding graphical user interface. I am using text box for editing files. I want to show the line numbers and graphical breakpoints along with text box. Can anybody help me in this? Thanks.

Thanks for you reply.
But actually I don't want to show the \ (backslashes) to the user in my text box.
Ok let me elaborate this problem little more.
I want to show my text box as it is in normal editors e.g. In Matlab editor. There is a text box and on left side the gray bar shows the line numbers corresponding to the text. Further more i want that the user should be able to click on any line number to mark specific line as breakpoint (red circle or any graphical indication for mark).

Hi teda,

Actually the report is created in webi java panel using RE SDK and is saved in Report Sample Folder then i'm saving it in user's personal category by following code
string query = "Select SI_PERSONAL_CATEGORIES From CI_INFOOBJECTS Where "
                     + "SI_INSTANCE=0 And SI_ID=" + reportID;
                InfoObjects infoObjects = infoStore.Query(query);
                InfoObject infoObject = infoObjects[1];
                Webi wreport = (Webi)infoObject;
                ObjectRelativeIDs personalIDs = wreport.PersonalCategories;
            /personalIDs.Add(Convert.ToInt32(categoryID));
               infoStore.Commit(infoObjects);
But the report is presents in the Folder also and in user's personal category also.
I dont want the report to be in the folder (Report Sample) if i saved it in user's personal category.
How can i do that?
any idea.
Please help me.
Thanks in advance

How to get the data from struct data type using java code.

Hi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.

Dan

In Snow Leopard you update Java from Software Update (in the Apple menu). You can check your version by opening Terminal and typing
java -version
(don't get creative and type anything else)
The latest version is 1.6.0_65.
