How would you have an event recur weekly? monthly? Yearly?

How would you have an event recur weekly? monthly? Yearly? I want to be able to insert an event for a weekly occurring meeting, however.... I don't want to have to insert it for every occurrence myself.

Hi,
If you are using 10g, this is trivial using dbms_scheduler
e.g.
grant create job to user_that_runs_insert ;
Then as the user do
BEGIN
dbms_scheduler.create_job(
job_name => 'weekly_meeting',
job_type => 'STORED_PROCEDURE',
job_action => 'weekly_proc'
repeat_interval => 'FREQ=WEEKLY;BYDAY=SUNDAY;BYHOUR=20;BYMINUTE=0;BYSECOND=0',
comments => 'job runs every Sunday at 8pm',
enabled=>true);
END;
Instead of weekly, you can just as easily to monthly or yearly.
If you don't want anything to run but you just want a list of dates that is on a weekly schedule you can use dbms_scheduler.evaluate_calendar_string in a loop to figure out which dates fall on a certain pattern. Docs and an example is here

Hope this helps,

If you lose your ipod touch and you have a warranty how much would you have to pay to get a new one?

if you lose your ipod touch and you have a warranty how much would you have to pay to get a new one?

Full price. Warranty covers only manufacturing defects, not you losing the iPod.
Perhaps homeowners insurance of your credit card plan, if you used a credit card to purchase the original iPod, might cover all or part of the cost.

How would you realize a "blinking"-Effect

The question narrows down to : Which is the best solution to trigger each 0,5 seconds an event (on the JavaFX thread) ?
I could do this with a TimelineAnimation or with a Task<Void>, the problem withthe Task is that I have to update the UI with Platform.runLater() each time which is an impact on the overall perfomance. On the otherhand the TimerLineAnimation is useful to update a property and I do not think that it is the approriate method to realize a blink effect.
How would you do this ?
E.G. I have a circle. This shape is supposed to change its Color every 0,5 seconds (And there can be many of this circles..)

I would use some kind of Transition, not because of any performance consideration but merely because it will keep your code cleaner. Used properly, a Task with Platform.runLater(...) to update the UI will be as efficient as anything else, but it can be a bit tricky to get it right (and using Transitions, you delegate the job of getting the code right to the JavaFX team, who are probably better at this kind of thing than either you or I).
The Timeline will actually animate the transition between property values. Almost anything you want to do can be expressed as a change in property; your example of changing the color of a Circle simply involves changing the value of the fillProperty. So using a Timeline will fade one color into another.
If you want a "traditional" blink, you could two PauseTransitions with the onFinished event set to change the color.
This compares the two approaches:

How would you detect a ground like this:

I have made racing games in the past, but never a side scrolling type.
Im trying to make one similar to this: http://www.gamesfreak.net/games/Cyclo-Maniacs_3730.html
But how would you keep the player on the ground? well not stuck to the ground because we would want the player to be able to use things like ramps.
Would it be a hit test? hmmmmmmmm Any ideas? anyone.

Oh i apoligize. I pressumed because of the popularity of box2D you meant that. Well the code I have so far does a OK job for physics. Allthough i made it in intensions of a platform/side scroller. But its ok. I guess it could possibly be modified for a car or something.

How would YOU retype these old XM08 types for use in an ABAP OO method?

The XM08 function group has the following type declarations:
TYPES: BEGIN OF mmcr_drseg_co.
        INCLUDE STRUCTURE cobl_mrm_d.
TYPES: cr LIKE drseg_cr    OCCURS 0,
       unpl_refwr TYPE refwr,
       END OF mmcr_drseg_co.
TYPES: mmcr_tdrseg TYPE mmcr_drseg OCCURS 0,
TYPES: BEGIN OF mmcr_drseg.
        INCLUDE STRUCTURE drseg.
TYPES: cr LIKE drseg_cr OCCURS 0,
       co TYPE mmcr_drseg_co OCCURS 0,
       sm LIKE drseg_sm OCCURS 0,
       charact TYPE rbcharact_instance OCCURS 3,
                                       "instances of characteristics
       uebgmat TYPE matnr,
       uebrblgp TYPE rblgp,
       selkz_db TYPE selkz,
       rblgp_old TYPE rblgp,           "rblgp before aggregation
       END OF mmcr_drseg.
How would YOU redeclare these types so that they work in an ABAP Objects class?
Some of the "fixes" are easy, like replacing "LIKE" with "TYPE:".
But what about the "INCLUDE STRUCTURE" and the "occurs 0" specifications?
The reason I'm asking this is that I have to call a method from ZXM08U16 and I'd like to be able to pass this method exactly what XXM08U16 gets from SAP, i.e. the table E_TDRSEG of type MMCR_TDRSEG

David,
I wonder it can be directly in ABAP (I would like to hear opinions from others as well!), I needed to use Data Dictionary as well:
TYPES: BEGIN OF mmcr_drseg_co.
        INCLUDE STRUCTURE cobl_mrm_d.
TYPES: cr TYPE z_tt_drseg_cr,
       unpl_refwr TYPE refwr,
       END OF mmcr_drseg_co.
z_tt_drseg_cr is a table type created in SE11, based on structure drseg_cr.
the way to create internal table and work area, based on the above:
DATA : gt_... TYPE TABLE OF mmcr_drseg_co.
DATA : gw_... TYPE mmcr_drseg_co.
hope this helps some
ec
UPDATE : Rich is right, it is possible to do it only in ABAP with the DEFAULT KEY addition.

How do you have a file automatically open in mail, like a Constant Contact email?

How do you have a file automatically open in mail, like a Constant Contact email?
Thanks,

If there is a way to automatically open an attached file in a Mail item, it is not one that I would use, because I want to stay in control of my Mac! Who is it from, whats in it and so on... To me bad idea but then the choice is yours.

How would you write a "wildcard" in a filefilter?

How would you go about to have a wildcard instead of the "*" in the following filefilter;
          File[] files = new File("./resultat/resultat_" + "*" + "_" + index[0]).listFiles (new FileFilter () {
                public boolean accept (File file) {
                    return ! file.isDirectory ();
          });All help appriciated
- Karl XII

Shouldn't "a*" accept all files that begins with "a" and ends with whatever?No. "*" in regexp is a not a wildcard match. Instead it matches one or more instances of the preceeding
value.
Therefore "a*" will match "a", "aa", "aaa", "aaaa" etc but will not match anything which does not end in
an "a".
The following might help you out. (not the most elegent expression but it will do
import java.util.regex.*;
public class RegExp{
public static void main(String[] args) {
Pattern p = Pattern.compile("a*b");
Matcher m = p.matcher("aaaab");
System.out.println(m.matches());
// interesting bit here
// match one or more occurances of any characters in the ASCII charset (the \\p{ASCII}* bit
p = Pattern.compile("hello_\\p{ASCII}*_b");
m = p.matcher("hello_wibble_b");
System.out.println(m.matches());
}

How would you pass more than 255 args?

I have an SFTP program that currently is only passed a single file. I am modifying it so that it will loop though an array of files to simulate an mput command. Originally I was just going to call the program with each file to be transferred as an argument but noticed the 255 argument limit. I am looking at potentially having 1500 - 2000 files to transfer at one time. I am just looking for advice on how this should be designed. One idea that was forwarded to me was to just create a listing of the files on the server and use that list file as my argument. Would this be the best approach for this issue?

I see no reason why you need an argument for every file.I would not necessarily need one for every file. Prior to our needing to use this for multiple files, it was easy enough to pass in one file as an argument. That is my question, how would you try to pass in a long list of files?Let's establish what you are concerned about. The 255 argument limit is on method signatures. From what you're saying here, you're talking about arguments being passed into your application from, say, the shell. Am I right?Correct, please see my clarified post. From what I have tested, the 255 argument limit appears to exist even for arguments passed to main.Ah, but arguments passed to main from the command line are passed into main as a single array of Strings, no matter how many of them there are. I have no idea what the limit on those is, but an array can hold millions of elements. I expect your shell will moan about that many, though.
As I see it, you have a few choices. Unless these files are all in different, arbitrary directories, you can specify a list of directories for your app to search. Or you can pass them all in one at a time, and see how you go. Or you can list them in a text file, pass that to your app and have it work them out. Or write a script that invokes your app multiple times. What you don't need, is a method that takes each file as an argument.Thank you for walking me through this. Would you mind telling me which way you would lean if you were designing this? The files will all be in a single directory on the server and I would not like to invoke the app multiple times as it creates a connection during each invocation. They're all in the single directory. Ok, are all the files in that directory to be transferred? If so, I'd just pass the directory name to the app, and have it iterate over all the files. If it's only to be certain ones, how do you know which ones? Is there some regex or filtering you can do on the command line?
If you are interested, the 255 argument limit for main that I tested was from this article:
[http://www.javaspecialists.eu/archive/Issue059.html|http://www.javaspecialists.eu/archive/Issue059.html]
It does die at 255 using Java 1.5.Like I said, arguments to a method are thus limited. But the args passed to an app are passed to main as one argument - an array. In short, that article is not relevant to your problem.

How would you go about saving an online image locally?

Say if you knew the url such as http://www.yahoo.com/img.jpg
How would you save this locally?

Read the answer in your previous posting:
http://forum.java.sun.com/thread.jspa?threadID=772451
Use the file as an InputStream to read the data and then use an OutputStream to write the file.
The logic is the same as reading and writing a file from disk once you have the InputStream.

How would you split a 10 GB root partition? Would you?

The system seems to be booting a little slow lately (been using Arch for more than a year now) and I was thinking of splitting the root partition to improve performance.
Right now the entire OS is on a single partition. I don't have a /home partition but I can see it's usefulness:
- files on /home are, in general, more frequently written (browser cache especially), which means less fragmentation for the root partition
- having a noexec flag for /home so no potentially dangerous software will run from there (and why would you need to run software from /home?)
- my /var folder takes up 102 MB, 9.706 files in 4.846 folders. Is there a filesystem that will deal well with many small files ? ReiserFS maybe ?
So how would you split (gigabyte-wise) a 10 GB partition into /, /home and /var ? And would you ? I've been told from the IRC channel that it makes zero sense. At least not for desktop use.
PS: I'm also switching from i686 to x86_64, so please take that into account as well. For instance I noticed that 64 bit software usually takes up more space than 32 bit.

How would you capture the stdout of Runtime.getRuntime().exec())?

How would you capture the stdout of Runtime.getRuntime().exec())?
Say you wanted to execute PKZIP25.exe from java using Runtime.getRuntime().exec(). How would you capture the output of PKZIP25 (the console IO) in a file so you could check the results?
Thanks
Bill Blalock

Thanks.
Could you explain a little more?
The program I am calling seems to be executing, as far as Java is concerned, but nothing happens. I imagine I have made mistakes in calling it but can't see the output to the console.
Should I use Runtime.getRuntime().exec() or Runtime.exec() for something like this?
I appreciate the help!
Bill B.

How would you read in each line of data and display them to message box?

How would you read in each line of data from the _.txt file_ and display the whole data using an information-type message box?
I know how to display each line of the .txt file data, but I do not know how to display the whole thing.
Here is how I did to display each line of data using the message box:
import javax.swing.JOptionPane;          // Needed for the JOptionPane class
import java.io.*;                         // Needed for file classes
public class problem3
     public static void main(String[] args) throws IOException
          String filename;          // Needed to read the file
          String categories;          // Needed to read the categories
          // Get the filename.
          filename = JOptionPane.showInputDialog("Enter the filname.");
          // Open the file.
          FileReader freader = new FileReader(filename);
          BufferedReader inputFile = new BufferedReader(freader);
          // Read the categories from the file.
          categories = inputFile.readLine();
          // If a category was read, display it and
          // read the remainig categories.
          while(categories != null)
               // Display the last category read.
               JOptionPane.showMessageDialog(categories);
               // Read the next category.
               categories = inputFile.readLine();
          // Close the file.
          inputFile.close();
}I think I need to change here:
// If a category was read, display it and
          // read the remainig categories.
          while(categories != null)
               // Display the last category read.
               JOptionPane.showMessageDialog(categories);
               // Read the next category.
               categories = inputFile.readLine();
          }but I don't know how to.
Could you please help me?
Thank you.

What is not understood about your question is which part of "read a bunch of lines and display them in a textbox" do you not understand.
First thing's first though: You do recognize that "read a bunch of lines and display them in a textbox" has a few distinct and completely independent parts, right?I'm sorry. I'm not good at English, so I do not understand what you said...
What I was trying to say is "How to display the whole lines of .txt file in single dialog box."We know that.
Do you understand that any problem can be broken down into smaller pieces?
Do you understand that your problem has the following pieces?
1. Read lines from the file.
2. Put the lines together into one String.
3. Put the String into the message box.
and maybe
4. Make sure the message box contents are split into lines exactly as the file was.
(You didn't make it clear if that last one is a requirement.)
Do you understand that 1-4 are completely independent problems and can be solved separately from each other?
Do you understand that you have stated that you already know how to do 1 and 3?
Therefore, you are NOT asking "How to display the whole lines of .txt file in single dialog box." Rather, you ARE asking either #2 or #4 or both.
If you say once more "display all the lines of the file in one dialog box," then it is clear that we are unable to communicate with you and we cannot help you.

How would you use Aperture 3 Labels & Flags in your workflow?

Now that A3 has the ability to use Labels & Flags, I'm trying to incorporate their use into my workflow but am struggling to find the most effective way.
I've used the star rating for selections & refining the selections. In A2 I used keywords on images to indicate actions on the images, however I never thought this was an elegant solution because unless I forget to remove them they stay with the images as I export them. Fundamentally though I think of Keywords as attributes of the image, so using keywords to describe actions was always strange.
One thing I liked with this workflow though was I could place multiple "actions" on an image since there can be any number of keywords. In A3 you can only assign one labe at a time. So this made me think of how I'd use Labels.
So thus my question: how would you incorporate labels & flags into your existing workflows consisting of star ratings & keywords?

I've wanted flags for a long time just to be able to mark where I left off on a project. My inelegant solution has been to give a terrible picture 5 stars. Other uses are to quickly get back to certain images.
I don't yet know how exactly I'll use labels or what other uses I'll have for flags, but I'm happy to have the added versatility. Between flags and labels, I have 8 new ways to mark and filter images. (10 if you count no flag and no label.) Sure one can do a lot with stars, stacks and keywords, but now one can do more.

How would you determine the total ram used by applets?

hi guys;
I have 2 applets.
One applet runs in a browswer. - in the microsoft jvm.
Another applet on another browser (or another page) - in the sun plugin.
How would you guys determine the total RAM (not just heap memory) used by these applets.
my strategy would be to open up the browser. and look at the memory next to that internet explorer process. Then I would open up another browser with applet and see total memory taken. Then I would subtract to determine the difference.
Does this sound correct?
Each applet has multiple jar files associated with it.
Stev

What you really should do is test your applet on a bunch of machines, like a 32 meg ram win 98, 64 meg ram win NT, and a 256 meg ram win 2000, and then give them a performance report under the different configurations. That's really what they're after (probably)
