Need help!!!! GUI problems with netbeans

i have a problem with the interface i created using netbeans.
i created a JFrame, inside it a JDesktopPane, and inside that 3 JInternalFrames. the problem is in one of the JinternalFrames, i have 4 radio buttons which i forgot to add to a buttongroup and whenever i try to do that, the GUI doesn't work anymore. The bigger problem is that if i undo the changes, the thing still doesn't work and i have to copy my backup project folder over the one i work on to get an output.
i tried to edit the source code to add the 4 buttons to a button group but netbeans won't let me since i created the buttons thru it not by writing it myself
please i really need help with this and i hope its a stupid thing i'm just overlooking.
If u need the code, i will gladly post it.
thanks in advance

if you're not using a netbeans-specific layout manager, copy the working code
into notepad, make the changes, then compile and run from the command prompt.
if all works OK, dump netbeans

Urgent I need help about Problem with macbook pro

The first sorry for my english,
I have a macbook pro buy it me almost one year ago, and these days me the mouse remains I want and cannot do anything have to wait a few seconds and it returns to work, and also when it puts in rest it touched all the keys and the trackpad but it does not answer, I have to close the screen and wait awhile to raise it and return to react, if someone can help me it be be to him very grateful, in addition the guarantee of hardware is ended in 8 days. thank you very much

Hi leptones, and welcome to Apple Discussions.
I'm not sure if your warranty expires in 8 more days or it already expired 8 days ago? If you're still under warranty, I would definitely call AppleCare or go to an Apple Store or AASP; they can troubleshoot it and determine if it's something that needs fixing while you're still under warranty (if you are).

Need Help Troubleshooting Problem with Shared Internet Connection

The setup:
DSL Modem/Router
Mac Running 10.4.4 connected to router directly, via ethernet cable
Mac Running 10.2.8 connected to router wirelessly, via ethernet bridge
The Mac connected by wire has no problems.
The Mac connected by radio works perfectly with web browsers and with Apple software update, but it can't connect to the AIM server and it can't connect to the GMail POP server. It can connect to those servers via dial-up however.
Any ideas on how to fix this?

Could you list the make and model numbers of your dsl modem and your wireless bridge please?

Need help.Big problem with battery

Hello all! I have HP Mini 110-3864sr for 3 years. I rarely used the battery but if I do it , my notebook was working for 3-6 hours. 15 of August I left for business trip and my HP stayed at home. When I came back on 22 of August, I switched it on, but I found that the battery doesn`t work at all. I have Windows 7 and I see that the battery status is 0% and no charging. I have done everything that I have found in the internet. I installed HP support assistant and did diagnostic from BIOS etc. Nothing helped, but HP support assistant says that the battery is OK. During the test it starts charging for 15 sec and that is all. I suspect that when I left the battery was about 10% and during the week It lost the power.
I know that it must work because as I have said before it cat run notebook for 3 hours +++. Please help what I have to do???

"I know that it must work because as I have said before it cat run notebook for 3 hours +++. Please help what I have to do???"
If you remove the battery and plug in the power adapter are you able to boot into Windows?
If that is posssible, then your battery has most likely failed and requires replacement regardless of what the diagnostic test has told you.
Notebook or netbook batteries are only guaranteed from new for one year. If you get three+ years of service life out of a notebook's battery, you can consider yourself quite fortunate.

NEED HELP. Problem with Video iChat

Hi there. I'm kind of new to the Mac world. I have a MacBook with Leopard. I seem to having a problem getting a video chat session up and running. I can iChat no problem but if I send a video chat invite the person gets it and accepts it but I receive an error message stating that i did not receive a response. The person that I'm sending the invite to is also on a MacBook using Tiger. I have a .Mac account and she does not. She is using her AIM account. I believe that she also received an error message about an invalid IP. Any suggestions?

Same problem.
But I can video chat with other people, this issue only affects 1 person, and they too can chat with other people, but when we try it fails with her seeing the IP error, I get a the other person didn't respond msg. Which just adds to the confusion. I used to be able to conference with her so this is a new error. Both video and voice only chats are affected, text chats still work.
I'm on 10.5.1 on a G5 Mac Pro and she is on 10.4.x on an Intel MacBook Pro
I can't be sure but it may have started after I upgraded to 10.5, but I also recently updated my Netgear (DG834G) firmware to V3.01.31. I've tried opening up various ports, checked everything that has been mentioned on here to date. The error is 100% reproducible with this specific person, and I can still conference with other people but I think they are all on 10.5.x

Need help troubleshooting problem with shadow images

Has anyone encountered this problem and found a way to
resolve it - I'm working in Captivate 2.
I've created a training project that includes screens
(slides) where popup windows appear. These popups mysteriously
appear as faint images in a subsequent slide. The only connection
I've been able to uncover so far is that recording the mouse click
in the subsequent slide causes the popups from the previous slide
to appear.
Thank you - Info Design

Problem with Netbeans IDE 5.0: Building Gui

Hello,
I have the following problem with Netbeans IDE 5.0 (I made the same with netbeans 3.6 and it works properly):
Step 1) Create a myJPanel class (new JPanel Form)
Step 2) make a simple operation on myJPanel such as adding a JTable.
Step 3) Create a myJForm Class (new JFrame Form)
Step 4) Adding a JPanel to myJFrame (default name jPanel1)
Step 5) Select JPanle1 within myJFrame and go to code-> custom creation code and write "new myJPanel();"
this should set the jPanel1 (and all its contents and behaviours) created
in step 4 equals to myJPanel();
Step 6) run myJFrame;
........ and nothing happens. It is dispalyed just a gray JFrame.
It seems that myJFrame is able to istantiate myJPanel() but is not able to paint it. what's wrong?
Hope you may help me,
thx

Unfortunately, Netbeans 3.6 files and Netbeans 5 files are not compatible. Except the Java source files, Netbeans uses other aditional files such as xml files etc for forming GUI and other reasons. I have also faced the same problem with you. Good luck.

I assumed this would help my problem with not being able to open apps like Preview or TextEdit since I installed Mountain Lion. Instead, first I'm prompted to enter a password, then once I do that, I get an error box telling me the Library needs repairing. So I click on Repair, and once again I'm prompted for a password, which I enter, then the same error box opens, and so it goes. Can anyone help me with this problem? I'd greatly appreciate it.

Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -Rh $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Step 1 should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary, and if everything is working as expected after step 1.
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Hello vashundara,
please say which Version of Forte and which kind/version your UNIX OS is.
There are some problems on AIX V4.3.x (Motif 2.x) and older releasese of
Forte (up to Forte 3.M.x) and so on and it is necessary to look what it is.
Maybe it is possible for you to say which widgets are the problem.

Genius needs to help! problems with my video card and system

Hey guys! I'm going to post my specs first so that you get a good idea of what I'm running on:
MSI Neo2 LS 865PE.....MAT=Slow
Pentium4 2.4C.....FSB=233=2.8C hyperthreading enabled ~>1.55V
Corsair TwinX 1gig PC3700.....memory on "AUTO" in BIOS with timings at 3,4,4,8 ~> 2.7V
Radeon 9700NP.....stock speeds ~>1.7V
AlienX case with 2 fan400 watt power supply and 6 case fans
Zalman Alum/Copper heatsink fan
1:I've had this motherboard for a few months now. I upgraded my video card from a nVidia Ti4200(128meg) to a Radeon 9800 a month ago, but I couldn't get it working at 8X AGP, no matter what voltages I threw at it. I returned it for a Radeon 9700NP hoping that it would work, but it still won't.
I'm using BIOS 1.9 and since there is no option to select your AGP speed, I could only try using ATI's drivers. Once booted into Windows, there is a slider you can move to select you AGP speed. On my machine It says that It has performed some tests and has concluded that AGP 4x is the best for my system....but my system supports AGP 8X!
I've moved the slider over to 8x (which requires a reboot) at least 5 times with each card but the slider refuses to move past 4xAGP after the reboot.
2: My second problem: I had an old stick of KingMax PC3200 and decided to buy 3 more sticks. Unfortunatly, the 3 I bought did not match the one I had, so I only put 2 of the new sticks I bought into my system. Immediatly, My system would crash, lock up, files were corrupt, and I got PLENTY of blue screens of death with a long message containing: 0x0000007 with all these other numbers and "0"s. I did a search online and found out I had a hardware incompatibility problem. I never got this with my old stick of ram.
I returned the 3 sticks of Ram and replaced them with the Corsair. Put my new Radeon 9700 in, formatted my hard drive....and within 24 hours, my system locked up 3 times, rebooted itself 5 times, and gave me the same BSOD as mentioned above with the same long message.
I didn't change anything except for the memory and the video card. I've been wanting to overclock, (thats why i bought the faster memory ) but I'm not sure what to do at this point.
I have my FSB at 233 but I'm scared to go any higher because of previous system instability at stock speeds. My RAM was running on 400 and MAT=Turbo with the most relaxed timings at 3,4,4,8.
I've given myself hours of sleepless nights formatting when my system wouldnt boot into windows; overclocking....etc. I NEED HELP. PLEASE. PLEASE. Anything could work at this point.
I'm trying to get more info on how to run my system at a 5:4 ratio, also.
If anyone has problems like me or knows what could be the problem with my system, please reply to this post, it would help me a lot. I've been trying to fix these problems for a few months now so anything is greatly appreciated.

Thanks a lot to you guys that responded. I brought my computer home this past holiday and I want to let you know where I stand as of now. I guess this thread is like my blog for my computer. I want to clear some things before my first post makes everyone confused.
1- I have only 2 sticks of memory in my system: the Corsair PC3700 TwinX 512x2
I returned the 3 KingMax I bought, and still keep my old stick just in case.
2- I am using the 400 watt power supply that came with the case. I read some reviews of the case and I know the reviewer did not have problems with the power supply. In my BIOS, there are some voltages it is weak on. Lets say: it it should be 5.00+, my power supply will be feeding it 4.96v or something like that, but I dont know, or think, that is a major problem...
3- My computer will refuse to boot if memory speeds are set at anything below 400. SO....if I want to use a 5:4 ratio and have to set my memory speeds to "333" in BIOS, my system refuses to boot.
4- This morning, I did manage to overclock my FSB to 250. Specs are as follow:
Memory Timing @3,4,4,8,4.....speed set at "AUTO".....MAT at "SLOW"
MY 2.4C's FSB was raised to 250 = 3.0gig
AGP/PCI frequency: 67.xx/3x.xx (cant go any lower)
CPU voltage: 1.5500
Memory voltage: 2.75
Video Card voltage: 1.7
Everything was fine for the whole day until I heard something click in my computer around midnight, and then seconds later, my computer froze and made a continuous beeeeeeeeeeeeeeeeeep. (you can imagine)
This "click" and system crash has been plaguing me for months now. I dont know whay it happens. I was just using AIM when I heard the click and my heart stopped.
My memory speeds have been set to "AUTO" even at the FSB of 250. But I don't know if this still means my system is at a 1:1 ratio. I know the BIOS then adjusts the memory to work at 500 if my FSB is 250...so I assume it is? I love 3gig, but somehow I feel that 2.8 is faster, since the FSB=233 running parallel to my memory, also at 233
A FSB of 250 is good enough for me, that's what I've been waiting 6 months for. If anyone knows how to set other ratios to achieve a FSB of 250+, please let me know, but as I said, my memory won't boot if its set at "333"

Hi Bryan,
I took your advice and decided to take a different approach to the problem I am having, I decided to stay somewhat with the basics with little knowledge I have about coding. I am new to this and I am trying to learn through the fire but it's getting hot so if you don't mind, can you tell me what I need to do to fix the error messages I am getting.
1. "else" without "if',
2. can't load my icon-a JPG
3. exception in thread amin
process complete.
4.Text area for displaying an iteration of the input
the code is not as long as the other one! any help will be appreciated. Also I am attaching the code to the GUI that does work but I can not seem to get the actionListener aspect to work. Thanks again.
//this one works and it serves as a model for what I am //trying to do in the fields. as well as designate a text area                                                              //where a each entry per iteration of input is displayed

Problem with netbeans IDE

hey! i am a learner of j2se 5.0 and am horrible at command line compiling. so i use netbeans IDE and well it has been doing excellently till now.
recently i had a porblem with ImageIcons and i found the exact problem which i was having but with repect to applets , that is, the images were not displaying properly. i have managed to solve the problem as far as applets are concerned, but it is not so with applications.
the thing is when i use the run function of the IDE, it displays all icons perfectly and its as if nothing is wrong.
it creates a .jar file which when i separately click to execute by going to its folder, does so but does not display any images. In fact it executes and behaves in such a way that it's exactly as if i have not used icons in the program- it displays everything else. should i change some setting of the IDE? but if some setting is to be changed, y is it running normally when run from the IDE( F6 key).
also when i used the command line (after some research to learn to use it) to extract all files from the .jar file, all the images were in it!!!as well as all the class files. so i can't even say that the IDE has not bundled up the images into the .jar file.
could some1 please help??i need help with .jar files and not applets.

first i deefined a method as shown in the Java tutorial
ImageIcon icon =createImageIcon("lion.jpg","name");
( within the contructor of the class)
then after completing the constructor for the class- (I am trying to display an ImageIcon on the background of a JFrame)
i provided the following definition after the constructor and b4 the main method:
protected static ImageIcon createImageIcon(String path,
String description) {
java.net.URL imgURL = LabelDemo.class.getResource(path);
if (imgURL != null) {
return new ImageIcon(imgURL, description);
} else {
System.err.println("Couldn't find file: " + path);
return null;
this is what i did-and when run from the IDE-it is perfect, but the jar file ggenerated when executed displays every single thing-all swing components e.t.c EXCEPT the image
the image is in the same folder as the source file- i checked because if not, an error is indicated- so that is not the problem here.
this same exact code works perfectly with applets and they execute perfectly both from the IDE and also when executed separately.
the same problem also iccurs when trying to display on labels and buttons.(only for JFrames not for JApplets)
the thing is in the java tutorial the method is given for applets and so my applets worked -so is there somethin i'm missing for frames- as far as i know they r very similar as far as usage is concerned.
