Help with BufferedImage - Graphics updating

Hello All-
I will try to explain the best I can, still new to Java2D so little confused
Hopefully the explanation makes a little bit of sense....
I have a tabbedPane, one tab with no graphics and the other tab full of graphics
The tab with the graphics on it is basically a bunch of rectangles that will change color depending on real time data I am pulling from a Mysql DB
For sake of performance I only want to have to repaint those rectangles when the data from the DB changes (i.e. repaint the rectangles when the bit changes from 1=good to 0=bad)
Any help on how to start implementing this would be absolutely wonderful
or if I could explain something any better please ask.
Thank you in advance

If you're thinking of just grabbing the graphics image of some component on the fly for rendering, that
wouldn't work well. Here is a link to some tips on doing your own drawing.
Again, yes, you may have to define your own component class. The only other alternative I can think of is to have a JLabel
that has an ImageIcon that holds your BufferedImage, and you update this by calling repaint after updating
the BufferedImage.

1) Swing related questions should be posted in the Swing forum.
Custom painting should be done in the paintComponent(..) method. You created a "pintarGraphico" method to do the custom painting, but that method is only execute once. When Java determines that the panel needs to be repainted, the paintComponent() method is executed which simply does a super.paintComponent(), which in turn simply paints the background of the panel overwriting you custom painting.

Please help with BufferedImage

hi,
I'm making a space invaders game and need some help with image buffering. I so far have classes for:
ImageHandler - which should handle the loading of images
GameEntities - which contains methods for the ship movements etc
AlienEntitiy - which will draw an alien and have methods for its movement, shooting etc.
SpaceInvaders - which extends Canvas and handles the main game
The problem is that when I create a new alien which has a call to the setImageName(String name) method, which should call the getImage(String imageName) method in ImageHandler, a null pointer exception is thrown.
I have searched my code and can't trace the error (by the way, this is the first ime I've used buffered image). Can someone PLEASE help.
Here's my code:
package InvadersGame;

            java.net.URL url = null;
            url = getClass().getResource(name);
            return ImageIO.read(url);
        catch(Exception e)
            System.exit(0);
            System.out.println("image not found");
            return null;
    public BufferedImage getImage(String name)
        BufferedImage image = (BufferedImage)images.get(name);
        return image;

I've tracked the problem to this bit of the code in the ImageHandler class:
public BufferedImage loadImage(String name)
        try
            java.net.URL url = null;
            url = getClass().getResource(name);
            System.out.println(url); //to check whether the image was found
            return ImageIO.read(url);
        catch(Exception e)
            System.exit(0);
            System.out.println("image not found");
            return null;
    For some reason the url = getClass().getResource(name); equals null even though the name I supply as an argument is exactly the same as the file name (alien4.gif).
I'm not too sure whether the problem's with my code or the way netbeans is setup. Can someone please help.

Color printing help with large graphics Reader 11.0.3

Good morning! We recently upgraded to 11.0.3. Windows 7 64-bit. We've had issues printing large color graphics from Reader 11.
For example, the PDF will have an intricate purple graphic with matching purple text blocks underneath. Print preview shows correctly, but when printed the graphic prints brown instead of purple. The purple text blocks print correctly. This seems to happen sporadically, but seems to be with complex graphics.
Documents from all other apps print OK and if we open this .pdf from Acrobat X Standard and export it to a .png file the colors print correctly.
The graphic files come from a myriad of sources and customers and we don't have control over the way the documents are originally saved or what apps are used to create the artwork.
Any idea why the graphics colors aren't printing and if there are settings we can adjust in Reader 11 so they will print correctly?
We've tried:
- Printing to several printers with different drivers and all yield the same results. (Toshiba eStudio 3530c with PCL6 and PS drivers, Epson Artisan 835, HP OfficeJet 8600, Samsung CLX-6200x)
- Adjusting the Overprint Preview settings under File -> Preferences and setting "Simulate Overprinting" under the Advanced button in the print preview window.
- Selecting "Print As Image" under the Advanced button in the print preview window.
- Adjusting the Document Color Options under File -> Preferences -> Accessibility.
Thanks in advance for any help!

Fastest thing you can try: use Windows Explorer to navigate to C:\Program Files (x86)\Adobe\Reader 11.0\Reader, then double-click on Eula.exe and accept the license agreement.
If that doesn't work, you can try using this tool to first remove all traces of Reader from your computer:
http://labs.adobe.com/downloads/acrobatcleaner.html
Then, you can download the full offline Reader installer from
http://get.adobe.com/reader/enterprise/
After downloading, restart your computer and run the installer before doing anything else.

I need help with a software update problem??

I recently got a new macbook pro and I was doing a software update last night as it was required but then when it started to do the update the computer installed the software and then a barring noise came from the mac and it tried to restart 4 times before it eventually came back on. The software trying to install was Fireware 800 I think. Can anyone help with this?

Try MacBook notebook forum to talk to other users, or OS Software (Lion or Snow Leopard)
Does not sound like an Apple OS update though.

Need help with "Nokia Software Updater"...Plz

hi
plz help me
every time i try to install
and it gave me this MSG
" Error 2738.Could not access VBScript run time for custom action."
my Lap work with W.vista
and i have N95-8GB
plz i need a help to update my phone

Please do a search on this forum for "6280 software update" and you will have your answer.
Many people have written here about Nokia software updater that tries to flash their 6280 phones with V6.10 (intended for the 6288) and then breaks their phones.
I myself was busy downloading the firmware for a friends 6280 that was just minutes away from being flashed with 6.10 when I came across messages on many sites telling about the issue with the software updater and 6280 phones. I managed to save that 6280 from sure doom.
If you also searched before hand you would not have this trouble.
You need to take the phone to a nokia Service centre to have it flashed now and get it into a working state.

Not exactly iweb - need help with a graphic for my site

This doesn't fit anywhere so dumping it here. I drew by hand a graphic I want to use with iweb to put on my site as my site's logo. Main problem is that getting the background transparent isn't working well as when it was scanned the scanner didn't back the background "pure" white. I have tried adjusting the whitepoint and setting the color depth down, but still no good. I don't know a ton about graphic program use. I have an older copy of graphic converter that came on this powerbook when i got it. I would be fine having the graphic loose the marker look and have solid fill colors - just I am not good enough with computer drawing tools to do it on the computer! So I either need to get a volunteer to help me out, or some help with some detailed instructions to get this to work out... (also I am broke so no cost/shareware is only option here)
many thanks!!!!
I can get you a scanned jpg of the pic if needed.

THANK YOU/___sbsstatic___/migration-images/migration-img-not-avail.png so the tolerance makes it not care so much about the gradations in color? what else is tolerence good for?
I have a cleaner copy now after someone suggested GIMP, so played with it last night - though couldn't figure out transparency - that was clear on converter- just not cooperative till these wonderful directions.
So now I know how to do it without messing with the pic, and with messing with it - both good lessons and got a bit brighter color out of the deal.
many thanks for the straightforward and clear directions, they worked perfectly/___sbsstatic___/migration-images/migration-img-not-avail.png extra strars for you/___sbsstatic___/migration-images/migration-img-not-avail.png

Please help with RAID driver update.

I need a little help with updating my RAID drivers. I have P55-GD65 motherboard and some SATA2 hard drives connected in RAID arrays. I am running Win7 64bit.
I already downloaded and installed:
“Intel P55 AHCI / RAID Drivers Ver: 8.9.0.1023”
from the MSI support web page. The setup file installed the “Matrix Storage Manager” and the “Matrix Storage Console”
On the same web page I see another download link:
“Intel Matrix Storage Manager Driver Ver: 9.5.0.1037”
It looks like I already installed the manager with the previous driver. Do I need to install this one too? What is the difference between both?
Also when I open the “Intel Matrix Storage Manager Driver Ver: 9.5.0.1037” I see 2 executable files:
“iata_cd.exe” and “iata_enu.exe”
I read the “Readme.txt” provided, but I couldn't find information on what is the difference between the EXE files and which one I should use.

I read the “Readme.txt” provided, but I couldn't find information on what is the difference between the EXE files and which one I should use.
Use either one. It doesn't matter in a functional way.

Help with Footers (New Update Glitch)

Hi there,
I'm in need of some urgent help with my website as upon publishing with the new update installed all my footers have changed.
I now have massive gaps between where my content ends and the footer begins on almost every page. Example.
Pages which are attached to the Master pages are not reading the same footer positions now. For example, my home page footer begins at nearly 1300 but the master it's attached to it should be closer to 950..... Everything was fine until the update today.
Any help would be appreciated. Thanks!

Maybe I can explain this a little better, issue is still going on, spoke with an Adobe representative but didn't get any helpful advice, actually got no advice other than to send the file in.
So here's my home page: you can see the gap between the content and the footer (with the footer starting at around 1300.
But then here's the Master page it's attached to, the footer is set to start way higher, this is happening on every one of my pages.

Hi,
I've been able to fully automate System Update distribution using Group Policy. this works perfectly.
I am now trying to achive the same functionality using scritps.
the problem: I get quite a few prompts for "License Agreement" - not the "master" initial one, only a few for the different installs.
here's my setup:
1. a local server is the repository.
2. I import a .reg file before installing "System Update" using an automated install.
3. after a restart, a command runs on the local machine.
here are the details:
registry settings:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Lenovo\System Update]
"LanguageOverride"="EN"
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Lenovo\System Update\UserSettings\General]
"IgnoreLocalLicense"="YES"
"DisplayLicenseNotice"="NO"
"DisplayLicenseNoticeSU"="NO"
"ExtrasTab"="NO"
"RepositoryLocation1"="***my internal server here ****"
"RepositoryLocation2"=""
"RepositoryLocation3"=""
"NotifyInterval"="36000"
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Lenovo\System Update\UserSettings\Scheduler]
"SchedulerAbility"="YES"
"SchedulerLock"="LOCK"
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Lenovo\MND\TVSUAPPLICATION]
*** network drive mapping here, this part works ***
also, I use this command to run the updates:
call "C:\Program Files\Lenovo\System Update\tvsu.exe" /CM -search A -action INSTALL -IncludeRebootPackages 1,3,4 -noicon
I am just about desperate... I would REALLY REALLY appreciate any help, hint etc :-)
Thanks for ...even trying... lol
regards,
Shay

I need help with the Security Update 2006-002!

Security update has really screwed up the two systems I've installed it on:
1) My G4 PowerBook refused to reboot after the update, getting only as far as the initialApple screen. Rebooting with a 10.4 install disk and using Disk Utilities to try to repair the disk either results in an "Unable to unmount disk" error, or if Repair does proceed, it is unable to repair the disk. I get a "Invalid node structure" error message, then a "Rebuilding B-Tree" message, then a "The Voluma Macintosh HD could not be repaird" message, and Repair quits with a "Error: the underlying task reported failure on exit" message.
2) On my Dual 2 GHz G5 desktop, Safari appears to be unable to load more than six URL:s in 6 tabs; I read about 20 webcomics all organized in a bookmarks folder, and my usual practice is to select "Open in tabs" to open them all at once. Heretofore Safari has opened all the tabs and all the URLs without a hitch. After the update it will open all the ttabs but only about the first six sites load - all the rest just sit there spinning their wheels.
Also it has hosed iChat on my Dsktop. iChat will open, but will not send or receive chats, and will not open the buddy window.
Also Also, the system frequently hangs, seizing up anywhere from 30 seconds to a few minutes, then resuming normally. Safari seems to be the culprit, but I can't really tell.
I need an update to recover from the effects of the last update.

I'm not very knowledgeable on macs yet being a new user (switcher) However, there appear to have been too many problems for too many people and too many systems associated with this update for it to be co-incidental. Take a look through the topics since the update appeared. My computer is brand new. The update did something that screwed something in the startup file (or whatever) The nice man in India helped me get the computer going by removing all sorts of wonderous things, this after his colleague in Cork had sent me all sorts of stuff to my work address to try out when I got home, like pram and nvram (which only made things worse) and other things. Now my computers fixed. Except that there's now no printer, it won't find the drivers off the install discs and any driver I load from canon isn't recognised or a script isn't recognised. I bought this thing to get away from problems like this on PCs!!!!
