  I downloaded Firefox 4 and it does not give me most of the tabs and that he said that I would get. The top of my page looks nothing like what they show. How to repair or return to the Firefox I had before. I can not even find anywhere on my computer to uninstall Firefox 4

• How to filter data according to internal application and in case if returns nothing outside the query must return all the lines

  create table ab (a number, b varchar2 (20));

  Insert into ab

  Select rownum, rownum. "" sample "

  of the double

  connect by level < = 10

  create table bc (a number, b varchar2 (20));

  Insert into BC.

  Select rownum + 1, rownum + 1 | "" sample "

  of the double

  connect by level < = 10

  Select * AB

  where b in (select b BC where b = "2sample")

  This query will return me 1 row, but there are cases where the value of the parameter b is null

  and that it should return all rows in the table

  as

  Select * AB

  where b in (select b BC where b = "2sample")

  which return specific values, but I want to change in a way when the inner query returns nothing then outer query should return all the lines and works as

  Select * AB;

  Is it possible to put in a single query

  Hello

  You seem to ask for different things.  You want all the lines AB when

  1. The parameter ("2sample' in the example) is NULL, or when
  2. There is no corresponding row in the 2 tables (which could happen even if the parameter is not NULL)

  ?

  Assuming you want the option 2, here's one way:

  WITH got_rnk AS

  (

  SELECT ab.*

  DENSE_RANK () (ORDER IN CASE

  WHEN b (IN)

  SELECT b

  BC.

  WHERE b = "2sample" - parameter

  )

  THEN "A".

  OF ANOTHER 'B '.

  END

  ) AS rnk

  AB

  )

  SELECT a, b

  OF got_rnk

  WHERE rnk = 1

  ;

  This does not assume b is unique in each table.

• How to read file returned by the file picker

  I'm going to obviously stupid here, but for the life of me I can't figure out how read in a text file returned by the file picker.  I am currently getting the good full path of the file in the file picker but where do I go from here?  BlackBerry.IO.file does not seem to exist in Blackberry 10 and I'm confused as to how I would use the HTML5 File API from only a file returned by the file picker path.

  Can someone please spit out a quick and dirty example showing me the rudiments of reading in the data file from a path returned by the file picker, please?

  Thank you very much

  DM

  Don't know if you have the path to the file, and then you left there. One thing to note. The file MUST be inside you bar (sandbox) OR you need to add the <> ermit > access_sharedermit >
  and then he can live the file in the shared folder on the device.

  Here is a code that you can use to read a file. I poached it our docs found here:https://developer.blackberry.com/html5/apis/blackberry.io.html

• How to open or return to the Panel tabs 2,3,4,5,6, etc. using a URL link.

  Hi all

  I have some problems with Spry Panel tabs. I use Dreamweaver CS6 and tried the code, as seen on this link URLUtils Spry help to open remote tabs and panels , but it did not help.

  My Tabs panel contains up to 6 tabs and maybe more that I do. I need help on how to return to the tab, I was after filling and display a form which is this tab?

  For example, I have form questionnaire on tab 3. How can I return to the same tab 3 after filing my form of questionnaire.

  Note here that when I click the button submit, the contents of the form are validated in the database, and the form will be redirected to the URL link that is attached to the submit button. This ULR link must have something comme.../interview.php?tab=3 or so it will load tab 3 once the page is updated after the presentation

  

  Also note that my site is still currently offline. It has not been added to internet as I'm just starting my project.

  Thank you very much

  Thank God I was able to identify the problem. The lnks tab are busy

  Here's what I did

  1. I created the tab 3, using the example, as seen on this link using Spry URLUtils to open the panels and remote tabs which I said was not helpful. In any case, I'm sorry for that. Please forgive me for my mistake.

  2 filled with content and adding a link tab = 2 #TabbedPanels1 what makes 3 tabs. See the image below

  

  My 2 tab is the tab text for more details .

  3. light that it worked, I replaced now the SpryAssets folder of the project that I worked on the SpryAssets folder I downloaded from the link using Spry URLUtils to open the panels and remote tabs and that's all.

  My conclusion here is that the SpryTabbedPanels.js that is automatically inserted in the SpryAssets folder of Dreamweaver has a fault code when it comes to adding links.

  So I give credit to the Powers of David which I believe is the author of the above code that solved this issue

• Adobe Acrobat 9 Standard can still see my old scanner to install.  How to force it to see the new scanner to install.

  Adobe Acrobat 9 Standard can still see my old scanner to install.  How to force to see the new scanner to install?  Scanner is recognized by and works very well under Windows.  Acrobat, however, still see Fujitsu fi-6130dj #3.  I need to see Fujitsu fi-6130dj, which is what is listed in the Device Manager.  (Windows XP SP3).

  Thank you for your suggestions.

  To provide more details and list what has been done to solve the problem but it is perhaps a better way.

  Background.  When you install a USB to a PC device it is listed in the device as installed Windows hardware Manager.  If you take the USB port of any device and plug it into a different USB port on the PC the PC will install the drivers for this device.  In Device Manager, if you define a variable system environment for the Device Manager to show devices not present you can see all time this can happen.  In this case, there were five facilities in device for a single material element Manager, a Fujitsu fi-6130 scanner.  The first quotation was Fujitsu fi-6130dj, then Fujitsu fi-6130dj #2, Fujitsu fi-6130dj #3 and so on.  Adobe Acrobat was the third instance of these drivers being installed.  Once I've cleaned of all device manager Fujitsu scanner installed I was able to have a single set of drivers installed for this Fujitsu but Adobe has always recognized the third instance of the installation of the driver and I could not understand how force it to see what has been seen in Device Manager, a single instance of the Analyzer installed (with no #3 behind it).

  Steps to try to solve.

  Repair Adobe installation - no luck - can still see the #3 the scanner instance

  Disable, uninstall, reboot, reinstall, reactivation of Adobe - no luck, same behavior as above

  The complete withdrawal of all scan related to software.  This includes drivers for ISIS in Add/Remove programs and all other related software.  This includes also delete the contents of the TWAIN_32 folder located in the root of the Windows directory and also included the scanner the removal of Device Manager.

  Restarted.

  Reinstalled complete sets of these both TWAIN and ISIS scanners - scanner disconnected.  Powered by installing Windows scanner back and let the drivers for the hardware.  Only at this point don't have installed Adobe see the new installation of the Fujitsu scanner and is more looked at for the #3 scanner instance.

• How can path constantly return to the standard settings, I change the standard settings?

  Hello

  I'm having some trouble with the drawing of the traces in Illustrator. Whenever I draw a new path, this new path appears in the standard settings. The definition "brush" turns back to 'base' and the 'variable width profile' return to the 'uniform '.

  It would save me a lot of time if I could change these standard settings in that I prefer.

  Can someone explain to me how to do this?

  Thanks in advance!

• I have lines on the screen of my iPad, how do I get rid of the lines?

  I have lines all over the center of my iPad, how do I get rid of them?

  You can try to do a forced reboot. Press the sleep and home for about 20 seconds. When you see the silver Apple, let go and let it reboot and see if that helps.

  If not... are the lines only in an application or see them whenever you edit the page? It is possible that the digitizer has problems, and so then it's time to call the cradle make an appointment at your authorized service provider or Apple store and ask them to look at. (Make sure that it is a service provider not anywhere that says they'll fix your device using an unauthorized service provider may void your warranty if your camera is still under warranty)

• How a TableView can iterate over the lines and get the cells?

  I need to iterate over all rows in a TableView without using events. I would like to get the total number of lines, TableRow and a cell of a TableColumn specified in the TableRow.
  
  Something like this:

  for(TableRow tableRow: tableView.getRows()){
      Cell cell = tableRow.getColumn(4).getCell();
      // do something to the cell 
  }

  Is this possible?
  
  Published by: Conzar on May 19, 2013 23:18

  However, the problem with the checkbox has been resolved so I don't need to iterate over the lines longer.

  Yes, don't use do not research to manage this is a much better solution, I just gave my search for a solution based on because you asked an iterative solution.

  Below (research) code produces no output.

  It works for me, I've included an example of executable, so you can try it.

  My guess is that you are not taking into account the fact that the research is just a glimpse of the cells of the table at a time in time.
  If you do a search for cell before show you the table on a stage, he's not coming back what it is because the cells are generated only on an as needed basis, and there is no need to generate all the cells before displaying the table on a stage.

• How can I force &lt; pre &gt; (or [code] bbcode) tags for the return to the line?

  I recently spent 12 Opera to Firefox.

  I use the world of Warcraft UI and Macros forum a lot and I use the {code} tag when posting scripts or macros.

  In Opera, {code} tags would be word wrap nicely, allowing me to see the whole code block;

  However, in Firefox, the {code} tag not dress and gives me a horizontal scroll bar;

  How can we force pre or {code} tags to word wrap in FIrefox? I guess I could get around this behavior with the CSS styles, but I'm a complete noob to how to start even with that. A tutorial step by step would be best.

  Thanks in advance.

  Then, you add the selector code as well.

  code, pre {
  white-space:pre-wrap !important;
  word-wrap:break-word !important;
  }
