Prob with Swing Refreshing --Help Me

Hii
I have created a GUI in Swings, i need to apply some changes with one button click, but
the changes dont get implemnet till i minimise and again maximize the frame,
I am using repaint() method to get it refresh ,but it wont work
Pls Help me if u can

Your Friend

if ur changing components and similar this usually does the work:
parentcomponent.validate(); //or revalidate()
parentcomponent.repaint();
where parentcomponent would be the container of the changed components.

Reversing with swing? Help!

Alright, before you guys flip out and say post it to the swing forum, why does the swing forum say read only? Now I have searched the forum but cannot find anything that deals with swing and the kind I am doing. So if you can provide some advice or some help, it would be greatly appreciated. This is my last hurdle to tackle in my school project.
I tried a StringBuffer approach but it kept giving me an error saying it would not work with JTextArea? Maybe the code was wrong?
This needs to take the text on the screen which I have and post it reversed when the "Reverse" button is clicked... I have been searching the web and these forums and all the different reverse methods and theories are confusing me, I try to copy them and get them to work but I just keep receiving errors. What is the best way to do this with using GUI?
else if (actionCommand.equals("Reverse"))
          reverseMemo = theText.getText();
/*Is this where I would put the reverse code?*/
theText.setText(reverseMemo);
     }Thanks,
Jess

Just write a method to reverse the text
read the string in reverse and start plugging the values into a string buffer (inside a loop of course)
then display results:
textfield.setText(stringbuffer.toString());
This is my last hurdle to tackle in my school project.I highly doubt it.
The fact you are asking this question shows me you did not learn anything about Java much less computer science. Your question has nothing to do with swing.

hi guys I'm sure this is easy for someone. My Program myTimeCalc.java fails to run with a nullpointerexception. I realise I am very new to this so if I'm doing something really stupid then hey its about time I learnt. So thanks in advance and any help greatly appreciated.

Hi Phill.,
I have altered your code. Just a little bit. take a look.
Please do changes accordingly. And better use NetBeans IDE for developing a swing application.

Don't ask people to reply by private email. Most Forum regulars believe solving problems should be a public, transparent process during which a first try at an answer can and should be corrected if someone more knowledgeable notices that it is incomplete or incorrect. Also, they get some of their reward for being respondents from being seen to be competent and knowledgeable by their peers (not to mention the possibility of collecting some of those precious Duke Dollars).
In addition, begging (e.g. "pleaaaaaaaaaaasee") is extremely unbecoming. It's especially annoying when it's coupled with vagueness about the actual problem. Go read the finj - mini-howto. If you have trouble writing the code, come back with specific questions.

al22,
You have 90 days of free AppleCare telephone support. If your machine is within the 90 days or you have already bought AppleCare (STRONGLY recommended) give them a call. The support is excellent, nothing like what you are used to with a PC.
Because you did not complete your profile we have no idea where you are located, what machine you have or the version of OS X installed. Please complete your profile, you can find it under Your Stuff in the upper right.

How to limit data range in a Line chart with Time Refresh Control

Hi All,
I have a Line chart with Time Refresh Control and I would like to make some constraints to this navigation.
For example, I would like to limit the user to navigate in a data range of 8 hours.
Is this posible?
Thanks in advance

Hi Pedro,
as far as I know, this is not possible using the time controls on an iChart. However, you may have some success by using your own time controls which call JavaScript methods exposed by the applet.
For example, you could begin by hiding the time and calendar buttons on an iChart, and creating some buttons of your own. For instance, to set the start date of a query (and thus the start date of the iChart using the query), you can use the following:
document.getElementById("appletID").getQueryObject().setStartDate(<date string>);
Using code like the above (look into the xMII script assistant and documentation), you should be able to build time controls which satisfy your requirements. The exact format of <date string> in the sample above will depend on the date format defined in the query template this script calls.
Hope this helps,
Sascha

Using Report tool with Swing Application

I'd like to use a reporting tool (Crystal Reports or anything else) with Swing application. Could anyone help me?

You have to pass the values are parameters to the Oracle Reports report. Take a look at this: http://www.oracle.com/technology/products/database/application_express/howtos/howto_integrate_oracle_reports.html
Also you can search this forum for "Oracle Reports"

E6-00: what's wrong with Belle refresh (and other ...

I've been following this forum and have always been up-to-date with E6-00 firmware. I've been almost happy with Belle and was expecting hardly the Belle refresh version for the Music player upgrade. What I got was - ? I don't know. Just the new version and no instant visible change. However... :
- the Music Player is the same. Meaning, no song search and still ridiculous user interface
- the phone tries to establish the data connection quite often even if no application is open
- the phone is hardly responsive from time to time (while looking for the network connection)
- the phone does not want to connect to the wifi. Restart helps.
- the phone loses the network operator and does not reconnect. Happened once (when roaming). Restart helps immediately.
- the Microsoft Apps: pursued upgrade. I personally do not need them. The screen is simply to small to use them effectively.
- (not a complaint) the battery life: I think the battery life is not really affected by the OS. Those complaining about shorter battery life should check how much time they spend using the phone, being connected to wifi, etc.
I'm very disappointed with the E6-00. I try to keep it positive but it keeps me down with every (new) issue. Does anyone has advice what to do with upper mentioned issues? I bought the phone ~2 months after it was available. I'm assuming that these first production series can have hardware issues? My phone was on reparation twice: for the notification light (hardware thing) and bluetooth issues (voice not heard over the bluetooth headset). The latter is still present I think...
I consider buying E71 since there's no other good (Nokia) phone on the market. What makes me sad the most is that my iPod touch does wifi connection and other things smoothlessly... But I don't want an iPhone (which is in principle the same as iPod touch), I just want a good Nokia.
Regards,
P

strelamcqueen:
I agree with your post except for the fact that Belle hosed my E6. Meaning: if you look at all my other posts, it's all about the GPS data functions that were awesome with the E71 then went away with the E6 on Anna. At least with Anna, there was an app called LeGPSData2 that restored most of the E71 GPS functionality. LeGPSData2 is not compatible with Belle. Sooo, I am currently using my E6 ONLY because of the decent camera.
Belle made the UI look pretty but that's it. I found the same problems with the responsiveness that you mentioned and issues with not connecting to my home wifi when I try to browse the net at home. There's nothing like downloading a bunch of big files only to discover that I've chewed up a bunch of data because the phone didn't connect to wifi. I put the wifi widget on one of my home screens and I make sure that I manually connect to wifi now before starting the browser. The Microsoft app via the upgrade were a joke. They actually took over Quick Office so that Excel and Word opened with MS Office Mobile. This would be fine but they open so tiny they are unreadable and they are not editable with MS Office Mobile for some reason. I removed the MS apps immediately.
My battery life suffered a lot after Belle refresh. With normal use as before the upgrade I would get home with about 50% battery with 3G ON. With Belle refresh, The battery won't make it through a full day with 3G on and I end up with about 25% battery at the end of the day with 3G off. Good thing I don't use much data through the day!
This is actually my second E6; long story but the first I upgraded to Belle and was disappointed with the loss of LeGPSData2 app. This one I was forced to upgrade to Belle refresh because while updating Ovi Maps one night, the update completely deleted the Ovi Maps app and I could not get it back without updating the OS to Belle refresh.
So I am with you. I too am very disappointed with the E6 but most of my disappointment comes from the software 'upgrades'. If Nokia would just leave well enough alone, all would be fine. I am sorry I have no advice to take care of the problems you and I are facing. I am in search of a new phone now and if I don't downgrade to an E72, I won't be getting a Nokia again. It's a sad story because I have been a die hard Nokia fan for a long time.

insert into teste (a, b) values (2, 'qwerty');
The first line is in the materialized view teste_mv but the second never appear.
I know it's a dumb trick but I can't solve this problem at the moment.
If somebody can help I would appreciate.
Thanks in advance

Materiazed view with fast refresh

Hi All,
I want to create a Materialized view with fast refresh.
I think for fast refresh we need to set up a materialized view log first before the MV gets created.
Can someone please provide the steps and the syntax to do this?
I am new to MV creation so appreciate any help in this regard.
Thanks.

Look up Materialized View Log and Materialized View ... both on the same page ... build the demo MV and you can modify the code to build any others you wish.

ACE HTTP Probe with regex

ACE HTTP Probe with regex
Hi,
I'm trying to setup a HTTP probe with expected string rather then a code (config below). I do a GET for the page then a search for a string in the response however it's not working, as probe appears as failed.
I've tested the connection to the server by using telneting and then looking at the page displayed to make sure the string I want to match is in the response.
probe http HTTP-PROBE
port 43050
interval 30
passdetect interval 30
passdetect count 1
request method get url /action=help
open 43050
expect regex action=help
Q. Is there anything wrong with this configuration and what I'm trying to achive?
Thanks,
Pritesh

Use "expect status" under probe config. expect regex doesnt work if expect status is not configured.
expect regex work flawlessly with static pages. It doesnt work all the time with dynamic pages.
Specially if "content-length" header is missing from Server response.
Hope it helps

Swing ActionListener help?

Hi there,
I'm trying to get to grips with Swing and I'm reasonably comfortable with laying out the GUI now. However, I'm still trying to get to grips with ActionListeners. As I understand it, you can have any old class as an ActionListener as long as it implements the ActionListener interface.....then you can just add this ActionListener to a component using .addActionListener().
Couple of questions though....
1. Is it generally bad design to just have a component call <whatever>.addActionListener(this) and then just implement the actionPerformed() method within the same class?
2. Do you have to define a seperate ActionListener class for each type of component, or can you use one ActionListener for, say, one whole GUI screen? How do you usually organise these things?
3. Anyone point me towards some decent tutorials on Java Swing event-handling?....preferably not the Sun ones, although if they are regarded as the best, I'll take 'em. :)
Thanks for your time.

URgent help need.
i need to link the page together : by clicking the button on the index page.
it will show the revelant class file. I have try my ationPerformed method to the actionlistener, it cannot work.
Thanks in advance.
