Creating an own textviewer-component - How to start?

Hello,
I'm going to write a program for comparing two texts for speed typing. For this I need a component which shows the text, shows for each line the character count and can highlight words (to show the mistakes).
E. g.:
Lorem ipsum dolor sit amet, consectetuer sadipscing elitr,   | 59
sed diam nonumy eirmod tempor invidunt ut labore et dolore   | 118
magna aliquyam erat, sed diam voluptua. At vero eos et       | 174How can I start?
Taking a JPanel and self-draw everything in paint()-method?
Using for every word a own JLabel?
Customizing a JTextArea?
Any ideas? :-)

Yes, that is the best approach. A text area provides everything your need:
Using a JTable is probably not a valid approach.Well, I am unsure of the OP's requirements, but his description suggests that characters (and maybe errors) are counted by line, thus leading to a rendering where one row in the GUI displays several information (columns) on one entity (which is "a line of text") - remember RowBasedTableModel?
Furthermore, quoting the OP (highlighing is mine): "I need a component which +shows+ the text, +shows for each line the character count+ and can highlight words (to show the mistakes)"
I interpreted it as if he enters text in some component (for which TextArea makes most sense), but the program then performs some analysis on the whole text, and only displays the result, line by line, in some other component.
It is not designed for entering multilined text.If the OP needs to both enter the text and display the result of the analysis in the same component (e.g. for real time analysis), JTable is certainly a wrong choice. I just did not read his post that way.
Highliting of errors will be difficult.During edition, yes, but at rendering time, no more than using a TextArea.

How do I prevent fullscreen to create its own space or how do I create a keyboard shortcut to such a fullscreen space

Hello,
In Mountain Lion, I could select from the dock icon the Options -> Assign To -> This Desktop to link back a fullscreen app to one desktop which allowed me to have a direct shortcut to my fullscreen app, e.g. ⌘3. In Mavericks this does not work and I cannot find how to disable the new space for fullscreen app nor how to create a keyboard shortcut for switch directly to that app once it's in fullscreen.
Any help would be much appreciated, I would hate to have to downgrade back to Mountain Lion.

The most typical solution for enterprise sites is to store their users credentials in an LDAP store such as Oracle Internet Directory (OID) or MS Active Directory. LDAP is an industry standard for extremely fast directory services over IP network infrastructure (http://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol).
In turn some sites store their user credentials in databases tables. Of course databases can be configured for fast lookups too, but it is a database centric solution where LDAP is designed to work across networks and is ideal for servers as a result which live and breath on the network.
In case of Java EE applications and especially those written in ADF, the use of these services isn't written into the application, but rather the application delegates this responsibility of configuring and providing these services back to the Java EE server. So for example Edwin's post is about configuring a WLS "security provider" to lookup user's info from the database, and here is another blog I wrote for MS Active Directory a while back (http://one-size-doesnt-fit-all.blogspot.com.au/2008/12/configuring-wls-with-ms-active.html). The main advantage here is you don't have every application baking its own solution, rather WLS provides a standard well tested way to configure the security lookups.
In terms of writing (i.e. creating users) to the security store over reading from it, indeed you need to build your own code. Ramandeep Singh Nanda has a nice post on doing this with OID through Oracle's OPSS: http://ramannanda.blogspot.com.au/2011/09/opss-adf-security-utility.html
Finally what sites like Amazon and Facebook do aren't necessarily good examples to follow as they're application's requirements are typically far in excess of a typical enterprise site, and in turn have often written bespoke solutions to deal with their scalability and distribution requirements. I dare say LDAP is a good choice for 99% of enterprises.

My mac book pro is creating its own ip address how do i fix this

please help

What OS are you running?
Did you redo the setup of the TC or just plug the new computer into it?
Did it work properly when you first started.. ie has this worked fine and has now failed or has it never worked?
How does the computer connect to the TC: wireless or wired?
How does the TC connect to the network and what mode is it running in?
Did you try a simple reboot of everything.. TC first and then, if unsuccessful, all the network in correct order.. modem .. TC.. clients with 2min gap.

My kids are getting older and they want to create their own accounts. How do we share all the music we bought on my computer for their computers?

We have bought music for many years on my account. My kids are all getting older, have their own devices, but still want to access the music we bought as a family when they were younger. How do I get their devices/accounts to all pair up within the cloud? Is it even possible?

You can't currently transfer content from one account to another account. As long as the tracks are on the computer's iTunes that they use/sync to, and your account is authorised on that iTunes, then they should be able to continue to use them.

How to start radeon script during boot?

My system hangs during startx. I have got input what to do but now, I need to create my own systemd.service file to start the script during boot. I have made following /etc/rc.local:
modprobe -r radeon
modprobe -r drm
modprobe radeon modeset=1
and get 644 permissions.
To start this service have I tried /etc/systemd/system/rc-local.service
[Unit]
Description=/etc/rc.local
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/etc/rc.local
[Install]
WantedBy=multi-user.target
and systemctl enable rc-local.service
When I boot the system I get the error:
Failed to start /etc/rc.local
Any suggestion will be appreciated.

I think it would be better to launch startx manually and look at the output! I also have a radeon card and use the oss driver. Nothing has to be done for it to work. Are you sure you haven't messed up something else? Something weird in your grub config? What about your files in /etx/X11/xorg.conf.d? Remove every "improvement" you tried to do, I'm pretty sure startx will work just fine then.

My Mac got hacked. I was working on a word document when the computer suddenly started typing meaningful sentences on its own that describes how the hacker is skillful. At the that time I was on a password protected wifi and file sharing was off.

This is the first time I get hacked this bad. I was working on a microsoft word document when the computer suddenly started typing meaningful sentences on its own that describes how skillfull the hacker is. At the that time I was on a friends wifi network that is password protected (not sure about the encyrption), the Os X Firewall was on. I was using the admin profile, however, file sharing was off. I'm very careful not to install any suspecious 3rd party software.
So far I have verified permissions and fixed some errors there, and changed passwords.
Do I have to erase/format my computer and reinstall the Os? If so is it adequte to use the internet recovery tool or will it use old and possibly infected EFI/Root files?
Would appreciate the advice of all the Mac experts out there. Thanks

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo launchctl getenv DYLD_INSERT_LIBRARIES; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; launchctl getenv DYLD_INSERT_LIBRARIES; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

How to start developing Xcelius component?

Guys,
When can I find steb-by-step explanation of how to start developing own Xcelsius components or modify existing?
I performed following actions:
1) installed Xcelsius 2008 Component SDK SP3
2) downloaded Flex 2.0.1 SDK from here:
http://labs.adobe.com/technologies/flex/sdk/flex2sdk.html
3) installed Flex Builder 3.0
Now I don't understand what to do...need assistance

Hi,
You use the Xcelsius Add-On Packager (comes with the SDK) to create custom add-ons. Within this tool you can define visual components, connections or functions that can be exported as add-ons.
In order to define a visual component (the most used type) you need to first create two separate swf files. One contains your custom flex component, the other contains the interface (property sheet) the user will be using in Xcelsius to interact with the custom component.
1. Custom flex component (swf)
Develop your custom flex component as you normally do in Flex, Xcelsius SDK is not involved in any way here. Define component styles and public properties that can be later be accessed via the property sheet.
2. Property sheet (swf)
It's the interface to your custom component. Here end users can change fonts, colors, bind cell values to component properties, etc. This is possible via the Xcelsius SDK. Using the SDK you get to populate the interface initial values values with the default custom component style and property values. You can also initiate bindings here between component properties and cell values.
Under C:\Program Files\Business Objects\Xcelsius\SDK you can find both the full documentation and samples to get you started.
Hope this helps,

How to Create a New Software Component

Dear All,
I am trying to prepare a list of steps to develop add-on products over SAP ECC 6.0. I was just wondering how to create a Software component for my namespace development, which I would like to assign my development package to.
Any ideas or guidance is highly appreciated.
Regards
VG

Hi VG,
I think I am just facing the same issue right now. Like you we do not want to do XI/PI development. We registered namespace and starting on developing a product based on ECC, which should be on a seperate namespace. We have read of AddOn Assembly Kit, but we don't have it for th emoment. We might have it at a later stage.
Still we would like to create an own Product and SC for shipment purposes. We created Product and SC in SLD but we are not able to select it in the SE80 dialogues of creating development objects. We haven't found away or documentation on how to sychnronize the SCs from SLD to ABAP system.
Is it possible to create SCs in the systme directly which will then show up for development objects?
Is it mandatory to have the Assembly Kit? (costs good money)
Is it possible to do all that in a later stage? (we saw it's possible to reassign SC for dev ojects)
I know it's been quite some time, I would still highly appreciate a feedback as SAP docu is very limited.
best,
Stefan

Is this the start... Verizon is blocking Google Wallet which is very nice, and you probably don't know they are creating their own Verizon Wallet

I have been with this company for over 10 years and frankly I always overlooked one thing wasn't to keen on and that was some of the services Verizon offered on their website which many of the account related services they have as apps so you can view from your phone are good and useful. I have been an Android user since the first Moto Droid to the Incredible and Inc2, then I though I was gonna go iphone, until I was able to use one for a month. Don't get me wrong it wasn't bad it was my brothers 4G on another network when he upgraded to the 4GS. Anyway no real problems other than Android just has more to offer so I went with the Nexus Galaxy and stayed with Verizon, after I was flipping a coin to go to Sprint. Anyway the reason I am leaving Verizon is due to their attempt to create apps to try to compete with googles apps and Verizon charges... you can find most for free from the droid market(which is the Play store now) such as Navigation. The free Google Nav is awesome, I also have google voice(free) so I get text messages emailed to me and vmails emailed and texted to me as well as being able to listen straight from phone by pushing play by the missed call. Verizon continutes to create these apps that also cost money and aren't near as good. I actually feel bad for the people who think the VZ nav is in fact the google nav. Now they are blocking a new service of Google's called Google Wallet. It's free and really cool, but Verizon blocks you from installing it or using it and Verizon is spending over a 100,000,000 dollars to create their own Wallet APP that i'm sure won't be free. So it's not that one app as to why I am leaving, its a number of things that as an experienced user and add the fact that I work in the tech industry, in sales that I Verizon taking advantage of customers, and I don't work that way or like it. Okay you go buy a verizon phone, it will have the VZ Nav right there on the home screen, however there will be no google Nav, and for newbies they usually think this is the navigation everyone talks about. You have to go download the Google Maps which is a turn by turn navigation always up to date and is awesome. I watch my kid driving down the road at all times for free. My point is now that their blocking Google Wallet because they are creating there own wallet, which won't be as good, and probably cost money to even spend money meaning they will charge for it. What is the next brilliant thing that Google comes out with that you can intergrate into your Google services. So what is the point of trying to compete with Google on apps, I mean the Verizon wallet? Why it makes no sense. Why block an app thus not giving you the luxery. They have their reasons of course such as security, and other reasons that it could cause problems but, hey if you dare to spend the outrageous amount of money to activate your hostspot to connect your computer wirelessly in a park. 75% of the people who do this are going to be on an unsecured network that anyone can connect to even with security turned on. So they say there worried about security on the wallet app, because someone may cold get access to your small amount that most people keep on the google wallet but the wireless hotspot is putting much more that money out there. it's putting personal things and files on your computer out there. I just dont' get why they can't provide their songs and ring tones and apps that allow you to see you data usage and leave the apps for the Google market. For you who don't know please download google maps and you will have an awesome navivation. Also google talk, voice, chat, and there apps on the google market for free such as a punch clock for time. I saw one for over $14 on the verison app store. So stick to what you are good at ,and don't block apps that other companies aren't blocking including at&T now, and they were in on the $100,000,000 to create this app along with Tmoblie and Verizon. I use an android because of the capapbilites that google gives you, and the apps that they offer for free or no money. Go look in the Verizon apps and see how much you will pay. Most that cost money come preinstalled on your phone so all you have to do is use it and you start getting charged. This is a 3 year decision making. I don't like that people can easily get charged for services without even knowing just because the app was installed and they used it once. Just stay with what your good at and let the android users rightly use the google apps. After all Google Saved your business if you really want to think about it. If you didn't have the android OS, how many sales would you be getting? Where would your company be. This app was developed by Google which means it ties into everything else such as making online payments with the google card. Blocking APPS developed by the developer of the Operating System that single handedly changed the game, and has Made you as a company far better off than you would have ever been had they not developed android. Not a good Idea. Bite the hand that feeds you.

Flashbuilder 4 how to create custom folders in component explorer

Hi, I was wondering if anyone knew how to create my own folder in the components explorer? I know that when I create a new component it gets added under "custom", but I want to create my own folder and insert an image next to the component. I've searched everywhere and cannot find a solution. Thanks in advance!

I tried that and no go. This was the only tutorial I could find on the subject but it didn't work.

Help! My ex boyfriend and I used to share apple ids. I have since created my own however my email is still linked to his I'd and he receives my text messages from an email address of mine on his ipad that I also receive on mine! How do I remove my email?

My ex boyfriend and I used to share apple ids. Since we are no longer together, I have created my own apple id and associated my email address for texting on my ipad. However, he still receives my text messages that go to my email address on HIS ipad! I don't have his apple id password so I cannot delete my email from his iTunes account, nor will he give it to me. I just don't want him to see my text messages! How do I delete it from his ipad?

Each of you need to have your own apple id's instead of sharing is the best way. But you can go to each phones settings, messages, send and recieve, and down to start new conversation from, and make sure each of you have your own email address with a check mark beside of it not the same address.
