Underscore that causes an exception in a toolbar

I use Netbeans 7.4 release candidtate 2

(1) start the set of JavaFx - thank you very much.  It saved me many hours.
(2) overall, click on 'hidden split pane.
3) click on the tab "Source Code".
4) click the "Netbeans save project.
(5) replace HiddenSplitPaneSample.java with this code (see below).

(6) after start: click twice on the 'double' arrow (maybe three times) to view the options in the center pane.
(7) the second time, you should get the exception.  (See the Netbeans output window).
(8) you get the double arrow because dividerPositions() has the value too small; but maybe that's the way some users
would things 'divided '.

Why it's important to me.  I've included a bogus getWord() (see below) method.  In my will to getWord() app
in fact, go to the disc and place a word in human language selected by the user somewhere else.
Example: if they are selected English-language then getWord ("Add_One') will return ' add a ', displays the text for the buttons.
If they have selected Chinese then getWord ("Add_One') will return ' Chinese add Equivalent a" and show the form of the text of the buttons.
If he has no replacement in the getWord ("Add_One") file returned «Add_One»

The question is why underscore causes an exception?  I could easily replace the least points with
a dashboard (see below) because that does not cause the exception. But that raises the question of what will happen
When I use Hindi, Japanese or Chinese?  Is there a stray character here and there that will cause
This exception?

Also note that he had removed my underline feature: 'Add_One' becomes 'AddOne '.

The underscore character is parsed as an indicator that the next character should be a mnemonic, and the underscore character is then stripped. This occurs by default on the buttons, but not on the labels.

See the API in the labelled class. You can activate either analysis offshore, or you can use two underscore lines to represent an underscore character.

  • When Firefox crashes and restart is necessary, Firefox always try to open the same tabs that caused the failure before.

    I use tabbed browsing all the time. When I open a tab of a Web site that poses a problem, freezing Firefox (but not the computer), I find that I can delete the Firefox problem only by restarting the computer. I am so appalled to find that Firefox then tries to recreate the same set of tabs that caused the problem in the first place, causing Firefox freeze again. Usually I can get it out by closing Firefox and very long wait for Firefox to close completely so that it can be restarted again.

    This problem occurs in version 4.0 as well as in the latest version of 3 that I had. I remember that in some versions previous Firefox asks if you want to recreate your tabs or open in a new browser window. I always took the second option. This choice is no longer makes its appearance.

    Set the pref browser.sessionstore.max_resumed_crashes to 0 on the about: config to get page the on: sessionrestore page immediately with the first reboot after a failure has occurred or the Task Manager was used for the closing of Firefox.

    Which allows to deselect the tabs that you do not want to reopen, but will reopen the other tabs.

    See:

    To open the topic: config page, type Subject: config in the address bar (address) and press the 'Enter' key, as you type the url of a Web site to open a Web site.

    If you see a warning then you can confirm that you want to access this page.

    You can use the filter at the top bar of the on: page config to more easily spot a pref.

  • I've had my laptop for a year, and it is currently running Windows 7 Professional. I recently had a problem that causes the black screen

    I've had my laptop for a year, and it is currently running Windows 7 Professional. I recently had a problem that causes the black screen randomly with the screen turned on (I mean everything is black and I can't see a thing, but can still see the light of the LCD screen). This often happens when I open/close a window, browsers web example, the records, or even during the boot. I want to know how to solve this problem and if the upgrade to Windows 10 works for her.

    Hi Haolin,

    Thanks for posting your query in Microsoft Community.

    I do not understand that the screen goes black randomly, and I'll be happy to answer your query. Let me ask you;

    • What is the brand and model of the computer?
    • Remember to no particular change in the computer before the show?
    • When was the last time it worked?

    Video card problems are the most common cause of this problem.

    Try the following troubleshooting procedures in the order. If the steps described in the first procedure does not resolve the problem, continue to the next procedure.

    Step 1: Reinstall your video driver

    1. Right click on the bar tasks and then click Start Task Manager.

    2. Click on the processes tab, click explorer.exe, and then click end process.

    3. Click file, and then click new task (run).

    4. In the text box open, type explorer.exe, and then click OK.

    5. Click on the Start button , go into the Device Manager in the start search box, and then, in the search results, click on the peripheral Manager.

    6. Double-click on display the cards, right click the display device, click Update driver software, and then follow the steps in the wizard that appears. You can also visit the website of the manufacturer of the computer support and install the latest available graphics cards for the same model of computer you have.

    Note: After the driver is re-installed, you may need to restart your computer to complete the installation. You may also need to adjust the resolution of the display to its previous value. For more information, see change your screen resolution.

    Step 2: Search for registry problems

    1. Right click on the bar tasks and then click Start Task Manager.

    2. Click on the processes tab, click explorer.exe, and then click end process.

    3. Click fileand then click new task (run)

      In the text box open, type explorer.exe, and then click OK.

    4. Click on the Start button , type regedit in the search box, and then, in the search results, click on regedit.exe.

    5. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

    6. Click to select the WinLogon key and then in the right pane, click on Shell. The value of shell in the data column must be explorer.exe. If the value of Shell is not explorer.exe, double-click Shell, and then, in the value data text box, type explorer.exe, and then click OK.

    7. Close the registry editor and restart your PC.

    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base: How to back up and restore the registry in Windows

    If this procedure resolves the issue, you are finished. If this is not the case, proceed to the next set of steps.

    Step 3: Start the computer in safe mode and run system restore

    1. Click on the Start button , click the arrow next to Shut Down, and then click restart.

    2. Do one of the following:

      • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

      • If your computer has more than one operating system, use the arrow keys to select the operating system you want to start in safe mode, and then press F8.

    3. In the Advanced Boot Options screen, use the arrow keys to select Safe Mode, and then press enter.

    4. Log your computer with a user account with administrator rights. When your computer is in safe mode, you will see marked Safe Mode in the corners of your screen.

    5. Click on the Start button , type "System Restore" in the search box, click System Restore, and then click Next. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    6. Choose a restore point when your PC worked as expected, click Next, and then click Finish.

    7. Restart your computer normally.

    Important: When you use system restore to restore the computer to a previous state, the programs and updates that you have installed after this date are deleted.

    If these steps resolve the issue, you are finished. If not, try to repeat the steps and chooses an older restore point (if available). If that does not resolve the problem, contact your computer manufacturer or the technical support for further assistance.
