Problem with the JFrame maximum size
Dear all,
I need to make my application expand to the maximum screen size when
the user first starts it. I am using hte following code:
frame.setSize(getMaximumSize());
however if my JFrame has a border layout and I have added a component at the page end
"add(new JLabel("hello"), BorderLayout.PAGE_END);"
this component is not displayed on the screen until I maximize the JFrame manually by clicking on
the default "Maximize" button at the right top corner?
Does anyone know how to get the JFrame occupy the maximum screen size where all of the
components would be visible?

Problems with the background image size in a photobook
Hi there, I really need help here. When I make a photobook I want to display my images large, taking the whole page. To do that I put the image as a background and it's OK. My problem is that when I do this, iPhoto always crops it. I have to use the move tool to move the image up and down, left or right to chose a best position. I don't want to do this, I want my image to be shown perfectly from end to end. I have to resize the image in many ways, even used the book's native resolution but it still doesn't work. If I choose "fit photo to frame size" I end up with two stripes at the top and the bottom of the page.
Please help me, what size should I resize my image to, so that iPhoto displays it as it is?
Thank youHi
The fact you are using a Mac is why both myself and JCellini assumed you where using a pre IE7 version.
But the code you are using to test in IE will cause a problem with any 'virtual machine' such as crossover, because it cannot reference anything outside its own assigned section of the drive, and referencing the png in the way you are would be for it an invalid reference, it also would not work in any browser when you uploaded the site.
Change - background-image:url(file:///Macintosh HD/Users/myname/Documents/websites/test/Test/images/test_back.png);
To - background-image:url(images/test_back.png);
But if the region is not editable I would suggest you temporarily make it so, externalize your css to a css file, insert a link to the external css file in your head content, then lock the region once again. This way you will always be able to edit your css without worrying about 'locked regions'.

There is a problem with the font size of the itouch 4.
I was given a new ipod touch gen4th (ios 4.3.5) by the Apple authorized repair centre in Hong Kong three days ago. However. i found that there is a problem with the font size of it. It is different from my original one. Either the playlist or the words in the webpages , the font size is not uniform. Most of the words are boldfaced. Sometimes, there are some words are smaller in size. I don't know whether I can or cannot figure out the problem and tackle it, so, should I take it back to the repair centre? Or does anybody help me to fix it or give me some suggestions? Millions of thank.
What language is set in Setting>General>International?
Have you tried the standard fixes:
- Reset:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factoery defaults/new iPod -
Photoshop CS5.1 Crashes Upon Opening: "Photoshop has encountered a problem with the display driver-"
Every time I try to open photoshop I get a window that pops up and says:
"Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements. Check the video card manufacturer's website for the latest software.
GPU enhancements can be enable in the Performance panel of Preferences."
Then windows shuts the program down. The details of the problem are:

Nvidia Geforce GTX 560 2GB video card

12 GB of memory
The error happens so quickly that I don't have time to do anything. Please help. >.< I've been on hold for *checks phone* 2 hours exactly. Wow. It is a legit copy and was working last month with no trouble. I've updated the drivers and tried a few solutions that have worked for other people that I found on Google (such as disabling CUDA and setting my "power management mode" to "prefer maximum performance" on my video card) but so far nothing has worked.
Thanks in advance!It has stopped crashing because somehow it turned off "Enable GL Drawing" on its own because I could never even get a menu open. Not sure how it did that but I am grateful. I still get the error when I open Photoshop up but at least it hasn't crashed yet. At the time when it was crashing I never would have been able to get you the system info due to the speed that it was crashing upon just opening the program. In case you still need it:

Hi! I'm using a JFrame in a game I'm developing, and this should be resizeable within some bounds. This works fine for the minimum size, the user is unable to even try to resize the frame smaller than what I've set as the minimum size. But it seems like maximum size is a different issue - I can't find a way to bound how large the user may expand the frame. Of course, when it's extended to a larger size than my specified maximum, it's resized back to the maximum size (using a ComponentListener to detect resize attempts - this has to be done because I need a constant aspect ratio - and a maximum size). But I don't like this solution very much, I would rather find it impossible to even try to extend the frame larger than the bounds - in the same way one can set the bounds for the minimum size. Please help me!
Any suggestions anyone?See [http://forums.sun.com/thread.jspa?threadID=5342801]
The real issue is that setMinimumSize is declared in Window whereas setMaximumSize is declared in Component. Thus the two methods do not have complementary connotations.
Experimenting with workarounds posted on those bug report pages, I think this is the cleanest solution, even if it does involve using a painting method for something other than painting -- normally to be avoided. SSCCE:import java.awt.Dimension;

Problems with the Proxy Programme--Please help
Hi All,
I have written a simple proxy server in the form of a servlet. I changed the proxy config of my browser to connect to this servlet hosted on the default context(http://localhost:8080) of the Tomcat 5.0.25 . Well , this servlet internally connects to the proxy of the corporate LAN . The logic that I have applied is as follows. The servlet gets the request from the client (ie the browser in this case) , extracts the headers and contents from the request, sets them to a new request that it forms and finally send this new request to the proxy. When the proxy responds, the servlet collects the response headers and contents adn writes them in its response. To sum up , this servlet transparently carries the requests and responses between the client(browser) and the corporate LAN proxy. Now the problem is this. Let's say , now I am accessing http://www.google.com.The browser sends a request to my servlet with the following headers as they are extracted by my servlet.
ProxyServer:::>posting request
ProxyServer:::>headerValue::> headerName = accept : headerValue=*/*
ProxyServer:::>headerValue::> headerName = referer : headerValue=http://www.google.com/
ProxyServer:::>headerValue::> headerName = accept-language : headerValue=en-us
ProxyServer:::>headerValue::> headerName = proxy-connection : headerValue=Keep-Alive
ProxyServer:::>headerValue::> headerName = user-agent : headerValue=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; UB1.4_IE6.0_SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)
ProxyServer:::>headerValue::> headerName = host : headerValue=www.google.com
ProxyServer:::>headerValue::> headerName = cookie : headerValue=PREF=ID=1be27c0a74f198ca:TM=1082058853:LM=1082058853:S=bu6ORrygzm8AUkm8
ProxyServer:::>postRequest
I set these headers into a new connection opened to the proxy and post a fresh request to the proxy,which, in turn responds with the following headers.
ProxyServer:::>posted request successfully
ProxyServer:::>writing response
ProxyServer:::>writeResponse-->headerName = Proxy-Connection : headerValue = [close]
ProxyServer:::>writeResponse-->headerName = Content-Length : headerValue = [257]
ProxyServer:::>writeResponse-->headerName = Date : headerValue = [Tue, 13 Jul 2004 14:01:40 GMT]
ProxyServer:::>writeResponse-->headerName = Content-Type : headerValue = [text/html]
ProxyServer:::>writeResponse-->headerName = Server : headerValue = [NetCache appliance (NetApp/5.5R2)]
ProxyServer:::>writeResponse-->headerName = Proxy-Authenticate : headerValue = [Basic realm="Charlotte - napxyclt2"]
ProxyServer:::>writeResponse-->headerName = null : headerValue = [HTTP/1.1 407 Proxy Authentication Required]
ProxyServer:::>writeResponse exiting
ProxyServer:::>wrote response successfully
I write these headers back to the client. According to what I was thinking, the client ie the browser would open a new dialog box asking for username/password owing to the presence of the "Proxy-Authenticate " header. But it does not happen that way. Rather the browser stops responsding and displays a blank page. Does anyone know why it happens this way? I am pasting the server prog below for everybody's reference.

Thanks for your reply. Well , I initially I thought of not pasting the code,as it was too long. But I could not help it,as I thought I must show in code what I exactly meant. That's why I followed a description of my problem with the code. You could probably have copied the code and pasted it in one of your favourite editors to take a look at it. Did you,by any chance, try to read it on the browser? And as regards reposting the same message, I can say that I did it as I felt the subject was not quite appropriate in the first posting and I was not sure as to how I could delete/alter the posting. I am not asking for a code-fix,but some suggestions from some one who might ever have come across such a thing.Anyway, lemme know if you have any idea on it. Thanks... -
Problems with 'background' JFrame focus when adding a modal JDialog
Hi all,
I'm trying to add a modal JDialog to my JFrame (to be used for data entry), although I'm having issues with the JFrame 'focus'. Basically, at the moment my program launches the JFrame and JDialog (on program load) fine. But then - if I switch to another program (say, my browser) and then I try switching back to my program, it only shows the JDialog and the main JFrame is nowhere to be seen.
In many ways the functionality I'm looking for is that of Notepad: when you open the Find/Replace box (albeit it isn't modal), you can switch to another program, and then when you switch back to Notepad both the main frame and 'JDialog'-esque box is still showing.
I've been trying to get this to work for a couple of hours but can't seem to. The closest I have got is to add a WindowFocusListener to my JDialog and I hide it via setVisible(false) once windowLostFocus() is fired (then my plan was to implement a similar functionality in my JFrame class - albeit with windowGainedFocus - to show the JDialog again, i.e. once the user switches back to the program). Unfortunately this doesn't seem to work; I can't seem to get any window or window focus listeners to actually fire any methods, in fact?
I hope that kind of makes sense lol. In short I'm looking for Notepad CTRL+R esque functionality, albeit with a modal box. As for a 'short' code listing:

TristanHi,
Many thanks for the reply. Isn't that what I'm doing with the super() call though?
As in, in Main.java I'm doing:
setupProjectDialog = new SetupProject( frame, "Create Your Website Project", true );Then the constructor in SetupProject is:
public SetupProject( final JFrame frame, String title, boolean modal ) {
// Setup the JDialog
super( frame, title, modal );
And isn't the super call (since the class extends JDialog) essentially like doing new JDialog(frame,title,modal)?
If not, that would make sense due to the null pointer exception errors I've been getting. Although I did think I'd done it right hence am confused as to the right way to handle this,if so.
Thanks,
Tristan

My iPod Touch (3rd Gen) is having problems with the touch screen being unresponsive, too responsive, freezing and constantly resizing. It varies between not responding when I tap the screen and acting as if I double-tap or tap and hold when I tap. Every so often it freezes for a minute or so and then comes back. The scren is constantly changing sizes too such that I often can't see most of the top status bar or other edges. This makes typing almost impossible, ruins most games and generally makes everything difficult, but otherwise the iPod is working correctly. Powering off, shutting down apps, letting it sit have not worked. This has happened once before months ago, but the issue resolved itself somehow. Is this a common problem? Is there a fix?
Try this for the freezing

Or if they don't work put it into recovery mode

}Thanks for the suggestions. I did away with the GridBagLayout Altogether :-D
and put all the buttons in a seperate JPanel and added that JPanel into the Console tabs container which was using a BorderLayout this time. Take a look

Getting problem with the new java.util.concurrent package
i m using the new concurrency package of jdk 1.5 in my code. see the line:
Executor threadPool = Executors.newCachedThreadPool();
about this, api doc says Creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available
but i dont find this method to create new threads whenever required. please tell me about this.
in my code, in some rare cases many threads r created, and very difficult to detect the number of active threads.
as the previous one failed i tried with another one newFixedThreadPool(int). but here i got another problem. it works successfully but i dont understand what should be the size of the pool. i tried with 1000, it works well, but in a very rare case, it failed also. then i tried with 10000. but i m still confused, i dont know whether it would work always or not. with traditional threads my code never fails.
please tell me, what should be the size of the pool and also let me know what is the problem with the first one (newCachedThreadPool)The thread pool should not be more than 100 threads. Ideally you should only have a small number of threads per CPU. If your threads are not long running it is possible that you could add 10,000 runnables but on start a small number of threads. Note, adding a thread take a non trivial amount of time so while the thread is added, all the others could finish. This could mean the number of threads could be 140 or smaller.
Have you looked at the code to see what it does? -
Strange problem with the mail app on an iPad
I've got a bit of a strange problem with the mail app on an iPad - it's sending and receiving mail ok but won't let you delete mail. If you keep at it, it appears as if you have deleted mail (though takes a very long time as you just have to keep deleting it over and over again) - but the size of the app still keeps going up - reached 600mb so far, even though there is hardly any mail or attachments (goes up quite a lot each time you try to delete anything) - any idea what's causing this and how I can fix it?
It occasionally comes up with a dialogue panel saying to check my account settings, but I have checked those and they are fine. The little 'loading' icon just keeps spinning constantly too.go to Settings > Mail > your account > Advanced > Move Discarded Messages Into
and make sure that Deleted Mailbox is ticked, and not Archive Mailbox
You can also adjust how long the deleted mail stays in the trash immediately below that.
If you are talking about a gmail account, you may also have to login to your account on the gmail server and update the settings there. This is what Barney previously posted about that: -
Premiere Pro CS4 - Problem with the monitor program.
Hi. I'm not able solving problems with the monitor using PremiereProCS4. When I drag a photo (also only one photo) in the timeline and play it in the monitor program, vision in the monitor program doesn't run:black monitor or a little part of the photo appear... sometimes distort colours. Asus P5QPRO, Intel 9550 and Sparkle Nvidia GeForce 9800 GTX+ 1024 DDR3; last gpu driver and directX are installed. Different configuration of stratch disks were tested. Where am I wrong?
Dear Bill,
thanks for your answer and your article. I tried with your NTSC 4:3 720x480 PAR 0.9 and, "magically", no more problem!!! I used the script pocedure in Photoshop CS4 to resize my images. Now, before starting my workflow and hoping not to overuse your patience, I would like to indicate you my equipment and my target: I use a Canon Eos 7D (generally for still images, 90% are vertical, and just some videos) and I use Premiere Pro CS4 to burn a dvd (normal, 4.7 Gb or double side, more than 8 Gb) with a 16.9 lcd tv (I'm Italian); my camera save as .jpg and .raw (but why use heavy .raw files if I've to redute to 720x480?!??).
So, according to your "everyone wants the highest quality that they can obtain when doing theri videos..." and "your video project may vary, so you will need to plug in the dimensions for YOUR video project in that case", I've a question: which is the best for me?
And then:
1 - Premiere Pro CS4 havn't a batch or a script procedure for still image like PS (only for videos)!?!
2 - Premiere does'nt allow you to import images like 4.181 Kb (a too large dimension file error appears)!
3 - In the timeline of Premiere, after you dragged images, you can select them and right click to perform "resize to frame size": it seems to run good without problem, but what appen to the photo? Which is it's pixel?
4 - In the general preferences of Premiere you can to optimize rendering for "memory" or not: which is the best for you?
5 - I attached file with a screen of something strange in Premiere: dragging an image (the first of the project) in the timeline, the timeline appears distort (you can see the part in the yellow square): then, when I render the project and play in the monitor program, it becames normal.
Thanks! -
Space problems with the SAP Database MS SQL 2000
Hi,
Actually, I have a size problem with the database, I have MS SQL Server 2000 with Service Pack4 on a Windows 2003 Server environment that is my DataBase Server of my ERP ECC 6.0. On the other hand I have a storage where I have 229 Gb of free space used only for the database files of the SAP data and the SAP log file.
But when I check the DB space allocation on trx. DB02 I saw this:
3 Database files and 1 transaction log:
The 3 database files are: PRDDATA1 (size 15,313 MB used 15016 MB) , PRDDATA2 (size 14106 MB used 13984 MB), PRDDATA3 (size 14472 MB used 14352 MB) and the log file is PRDLOG1 ( size 1000 MB) all of them with no limit option and growth by 10%.
So I went to the SQL Enterprise Manager and I saw that my Database PRD properties and I got this information:
My database size is 44892.48 Mb size with only 1330.36 Mb of free space and that is alarming.
So the question here is how ,if I have a storage where the sap data is storing with 229 Gb of free space, can I make the database files grow up in order to use all the available space of my storage.
Can you help me please because it is critical being my productive system?
Best Regards
Erik EspinosaI resolved this issue myself. Thanks for all your help.

Function module based generic extractor - Problem with the selection
Hi all
The following is my code in the function module. I am able to get the entire data if i dont give any selections and the number of records is also correct. But when i select a MATNR value, it returns 0 records where as it needs to return 3 records. If i give selection based on bukrs, werks, lgort its working fine. But if i give selection based on MATNR, then it is not working.... I think there is a problem in the bold part of my code. If i debug, LS_MATNR is having the correct value which indicates that there is no problem with the value being passed to LS_MATNR from my selection screen of my datasource in RSA3. Even GT_WERKS is also having data. Please help.

Problem with the default selection screen condition
hi guys,
I have got some problem with the default screen given by the PNP logical database, P0000 infotype automatically populated according to the condition given in default screen.
Reg,
HariharanDon know what u r trying to acheive.
1) when u have specified PNP in the logical databse field of attributes of program, the SAP wil proivde u default PNP screen and here u can also add ur paramters if u want.
2) in the program u have to declare like
INFOTYPES: 0000,0001. "Etc
for all the infotypes u want to use in the program.
3) it is the GET PERNR event which wil fil all the p0000 and p0001 (internal tables for al the infotypes declared via INFOTYPES syntax as shown above)
4) after tht get pernr, u now have data in P tables and u can use it for further reporting.
5) refer below dummy code -
