Several windows and grid questions
Hello, I have a couple of Swing related questions that follow:
Q 1)
Imagine I'm writing a basic GUI that has 2 "windows": the main window and the about box window. Basicly there's a JMenu with a JMenuItem that has an action that will set the about box visibility to true.
My question is: what's the most correct way to do this?
a) declare both windows in the Gui constructor, having the main window's visibility set to true and the about box window visibility set to false, changing that visibility inside a actinPerformed () method
b) declare the main window in the Gui constructor, and then creating the about box window inside the actionPerformed method, when the MenuItem is selected
c) other. please explain
Q 2)
Is there any way to automaticly draw a grid within a JFrame or does it have to be done with Graphics' drawRect, drawLine and so on?
Thanks in advance.
Q1: c, have a getter for the aboutBox and instanciate when needed (also possible with b). If the user never clicks the menuItem, why instanciate and clean up later?
Q2: DrawRect /line

Overlapping Windows and Panels Question
Hi, I have photoshop cs5 for the mac and I want to display 2 images of my project. I did this buy going to window>arrange>New Window For "project name" I want to be able to see one zoomed out and just have it displaying in the top corner. I position this new window on the top of my screen, but when I click on my "main" window, the new one just goes behind it and disappears.
My question is can I have my "main working window" tabbed in photoshop, while I have the smaller zoomed out duplicate window floating on top of it?
I would like for the smaller window to always be on top of my "main" working window of my project even while I have the "main" window selected. Is this possible on the mac version?
To solve this, I can make both of them floating windows and position them so that they do not overlap, but this takes up a lot of room on the screen.
I hope this description makes sense. Thanks in advance.I have application frame turned on and it does not work. The navigator is ok, but its too small and you cannot edit in it like you can in another copy of the project.
I have seen photoshop work in the way I describe, but it was on Windows. Could this just not be possible with the mac os?
Thanks for the quick replies -
Several Iweb and godaddy questions.
Hello Folks:
Just to give you an idea of my proficiency with web design, I'm the equivalent of a student pilot who just soloed. Just enough knowledge to be dangerous and a threat to mankind. Here are my questions:
1. How do I use text editor or word to modify my HTML? I can view the HTML of my site, copy and paste, but can't get it back into iweb as other than alphabet soup. I specifically want to change the email address. I wrote the site having my personal email address in my address book and can't change it to the business email address by just re-publishing with the change to my address book.
2. I published to Godaddy and of course cant use the counter. I tried to follow the instructions after starting an account at Statcounter.com but don't know how to insert it then change it back to a web site. Same basic problem as the email.
2.1 Why would Mac consider something as basic as a counter to be proprietary?
3. Can't get the slideshow to work on Godaddy. It works fine on my computer. On Godaddy, the slide show bar at the very bottom does not publish. I get an enlarged photo with a border on only three sides, nothing at the bottom. I can also enlarge each photo one at a time with the same results.
4. Is the Iweb loaded on my Mac a watered down version? Seems like a lot of features may be lacking, especially if you want to do a business website like mine. I love my Macs and don't want to have to switch to some windows program, but need more than I see on Iweb.
My website is www.airlandandseaparts.com. I'm going to switch into windows hard drive now and see if the slideshow works.
Thank you very much.
Regards,
Kevin
Intel IMAC and Ibook Mac OS X (10.4.9)I wrote the site having my personal
email address in my address book and can't change it
to the business email address by just re-publishing
with the change to my address book.
You should be able to though... this is strange... Especially if you are publishing to a folder, then you should be able to re-upload the newly published files with the proper email address.
2.1 Why would Mac consider something as basic as a
counter to be proprietary?
The resources for the counter are hosted by .Mac. They can't possibly account for every variable as far as available resources on other hosts. (php, etc - stuff I don't understand nor want/care to but thats what it is about probably)
3. Can't get the slideshow to work on Godaddy. It
works fine on my computer. On Godaddy, the slide
show bar at the very bottom does not publish. I get
an enlarged photo with a border on only three sides,
nothing at the bottom.
Try re-uploading your slideshow_assets folder.
I can also enlarge each photo
one at a time with the same results.
This is how the non-.Mac slideshow works.

Apple Bluetooth Headset - Paring with Windows and Other Questions
Love my new Apple Bluetooth Headset, works great. My first one did have a problem with poor range but this one is a lot better. I've been wanting to use the headset as a mic. Windows XP finds the headset find but I can't tell if it's connecting or not. How do I tell the Headset what device to connect to? It's paired to my iPhone too so it picks up on my iPhone every time I try to connect.
Basically how do scroll through on the Headset what devices to connect to? Usually Bluetooth Headsets can be paired with multiple devices and you do certain button combinations to scroll through the paired devices.unlike some of the sony ericssons, the apple headset can only be paired with one phone at a time. that doesn't stop you from repairing it when need be, however...

Flash Player opens several windows.
Flash Player opens several windows and does not work. Uninstalled yesterday downloaded new rebooted and reinstalled. Same thing. Windows 7 Pro, Firefox 17.0.1 Usually leaves a blank window upper left on my desktop.
Try resetting your Firefox profile (if you have't already). Instructions to do this are partway down in this FAQ.
How do I troubleshoot Flash Player's protected mode for Firefox? -
My laptop opened with a grey flashing file folder with a question mark inside it . How do I open my laptop! I have tried force closing several times and restArting nope ! nada! Suggestions?
That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
With 10.4, 10.5 or 10.6 put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion, 10.8 Mountain Lion or 10.9 Mavericks, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7, 10.8 or 10.9 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead. -
Newbie Grid Questions - Windows 2008 v11gr2
Hi all
As stated I am completely new to Oracle and have managed to do an single instance install and am now attempting a Grid and then RAC install.
I have created 2 VMs and 5 disks. During the Grid install I stamped the disks so that they could be used for ASM and put them all in a disk group called Data. I selected External redundancy.
In the previous documentation I have seen that during the Grid install you select where to put your voting files and OCR files but this never happened for me, is this correct? Also how can I check I have clusterware installed correctly? The documentation says that the verification utility runs automatically and I think this happened as the Grid install completed successfully.
One concept I am having troubles with is if the clusterware is installed as part of Grid then why do we need RAC?
My questions are probably very general and cover a lot, but any help in the right direction would be appreciated.
ThanksHi,
In the previous documentation I have seen that during the Grid install you select where to put your voting files and OCR files but this never happened for me, is this correct?If you selected to Oracle ASM as the storage option for the OCR and voting disk files, then the Oracle Automatic Storage Management Configuration Assistant (ASMCA) configures Oracle ASM as part of the installation process.
If you did not select Oracle ASM as the storage option for the Oracle Clusterware files, then you must start ASMCA manually after installation to configure Oracle ASM.
There are two ways of storing the shared Oracle Clusterware files:
Oracle ASM: You can install Oracle Clusterware files (OCR and voting disks) in Oracle ASM disk groups.
OCFS for Windows: OCFS for Windows is the only other supported cluster file system that you can use to storage of Oracle Clusterware and Oracle RAC files on Microsoft Windows platforms.
Starting with Oracle Database 11g release 2 (11.2) and Oracle RAC 11g release 2 (11.2), using DBCA or OUI to store Oracle Clusterware or Oracle Database files on raw devices is not supported.
Also how can I check I have clusterware installed correctly? The documentation says that the verification utility runs automatically and I think this happened as the Grid install completed successfully.You can use Cluster Verification Utility.
The cluvfy stage -post crsinst command to check the specified nodes after installing Oracle Clusterware.
http://download.oracle.com/docs/cd/E11882_01/rac.112/e16794/cvu.htm
One concept I am having troubles with is if the clusterware is installed as part of Grid then why do we need RAC?I do not understand what you meant with GRID is grid infrastructure (software Oracle ) or grid computing (concept).
If is concept check this..

Been experiencing severe slowness and lock-ups with Firefox of late, which ends with a sudden drop in memory usage and me having to repeatedly shut it down through Task Manager. I have created a new profile and disabled hardware acceleration. I have tried disabling all plug-ins and extensions, yet I noticed that at times (not always) plug-in container was still an active process, which I don't understand. Why would it be active when there are no enabled plug-ins? I also noticed that when plug-in container is not active (showing under Processes in Task Manager) I do not have this problem and Firefox runs normally? I need to block plug-in container. Please help.
I have just tried on Windows 7 and used process explorer on that. I would expect the results to be displayed in a similar manner on Windows XP.
Plugin-container is shown as being run from Firefox, and in turn if I mouse over or left click the line for plugin-container .exe then under ''command line'' it tells me what is running, in my case at this instance it is Flashplayer and so it displays
.... \Macromed\Flash\NPSWF32_12_0_0_77.dll .... plugin ....
It is identifying it is FlashPlayer
The worry with your apparently unknown operation is that within the plugin-container it may be safe but if plugin-container is disabled maybe it could be malware and cause a problem. -
I noticed when I restart Firefox 4, it opens my previous tabs even I set the option "Open a blank page" and it opens blank page when I have "Show my windows and tabs from last time". Please ignore my question if you're already aware of this issue. Thanks.
Your previous tabs will not re-open or be available to re-open when starting Firefox if:

You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox.

My desktop IMac OSX 10.6.8 : IMovie '11: Trying to upload a home movie clip from my Panosonic camera model PV-DV203D. I've had this camera several years, and used it with Windows desktop. Now trying to work with my Mac. I have a USB cable, both ends fit, but iMovie '11 does not recognize it. Is there a driver fix for this?
What kind of Mac to you have? This camera is a tape based DV one that connects best with firewire and I cannot tell if your Mac has firewire. If your mac *does* have firewire, get a camcorder firewire cable and try again.
ETA: Oops, I am pretty sure that all the "desktop iMacs" have firewire, so you should be good to go. You will probably need a cord that goes from FW800 to your camcorder. -

New implementation - Client having issues with RAC and Grid on Windows
Client is starting a new implmenetation on Windows 2008 R1, Oracle 11.1.0.7. They have a 3 node RAC and Grid Control. They are having a number of issues and support is working through those issues. They are asking if there are clients on RAC and Grid on Windows. The Wiki shows a few customers on Windows, but was hoping to get some feedback. Tks.
There are lots of customer applications that are based on Windows RAC. And as mentioned above, it is very well supported by Oracle.
However, because of the security vulnerabilities of Windows, I've observed that most of the financial institutions and listed companies opt for unix based servers for all high profile applications and run only low to medium risk application on Windows.
Regarding maintanence issues, I guess it's going to be pretty much the same; there shall always be lots of bugs, lots of patches and updates just like an yother software; doesn't really matter if you are on Unix or Windows systems. As long as you purchase support, it's all good.
It's pretty much same concern regarding Grid Control on windows.
Cheers. -
Dock question: Can I turn off the expansion/condensing effects of Fan and Grid view?
Hi!
Can I turn off the Dock menu expansion/condensing animations related to Fan and Grid view (and the condensing effect of List view)? I find the expansion/condensing animations slow and detracting from an efficient workflow. I would rather have menus pop up immediately so I can instinctively move the mouse cursor where I can anticipate a file to be located once grid/fan view window launches, rather than have to track the expansion animation with the mouse cursor so that I can select the desired file once it lands in its fixed position.
Is there any known backdoor way to cease these showboating animations?
For the dock to be such a major addition to the Mac OS (when compared to OS 9), I am surprised that there isn't greater customization for it. Speaking of which, why can't we have the option of having more than one dock, for example? I would like to have one mounted to the bottom of my screen for applications, but also have one on the left of my screen for commonly-accessed files and folders.
I am all for stock settings that help to streamline features for users as a baseline, but the more tweakable options the better. I pay a premium for Apple products; who are they to tell me I can have only one dock?! ;p
I've taken a look at Docker and Deeper, but neither delivered the goods. Thanks so much!
P.S. I am still using Snow Leopard. I haven't heard of new dock options for Lion, so please clarify if I am missing out on a Lion innovation.
Thanks again!Take a look at Secrets, OnyX, or Tinker Tools. All of those have various undocumented preference settings that affect various animations.
