• How to calibrate the screens of Adobe products? For the most part, I'll use Illustrator and Photoshop.Can someone make a difference between the calibration and the Hardware calibration software using (Spider)? Thank you.

  How to calibrate the screens of Adobe products? I will mostly use Illustrator and Photoshop.Can make all the difference between calibration and the Hardware calibration software using (Spider)? Thank you.

  I use U2415 from Dell.

  I use the Spyder Pro 4. The process is quite simple - install the software, plug the Spyder and follow the steps listed in the program. I would recommend also, install the latest version of the software directly from the site of Datacolor instead to install from the disc supplied (probably outdated).

• Make a difference in the number of records

  Hello
  
  Oracle9.2
  Windows
  
  
  Table A - records - 627255 total
  
  I want to pass some basic criteria records to a new table TAB_B, but implementation difference in number of records before and after the move.
  
  SELECT COUNT (*) FROM TAB_A WHERE the TIMING < (SYSDATE-150)-* 539911 *.
  
  CREATE TABLE TAB_B AS SELECT * FROM TAB_A WHERE the TIMING < (SYSDATE-150)
  
  SELECT COUNT (*) FROM TAB_B-* 539934 *.
  
  What can be the reason?
  
  
  Regarding

  SYSDATE is not static. It keeps ticking with impatience...

  And I suspect that you have a few 'ticks' between the time you did the count (*) and the create table.

• Material of restoration to the original state of the manufacturer will make legitimate recovery discs work?

  Hello.

  Back story:
  I tried to create a system to dual-boot with Windows XP and Windows Me on a PC from Hewlett Packard, model a350n, to facilitate access to the old and more recent examples of software in my computer.  Operating systems that are installed properly, however, when running Windows Me, I noticed that the system has detected a large number of hardware problems and a number of missing drivers. I have no problems the first time I installed Windows Me, and I realized that this must have been the existence of partition recovery console Hewlett Packard, who was at the current time, where the Windows Me operating system can locate the necessary drivers for the PC to operate.  Since the deletion of this partition (which I foolishly declared unnecessary from there), problems of hardware in the BIOS, PCI slots, sound cards, etc. exist in abundance.

  Issue to be addressed:
  The main concern is this: I have no legitimate recovery CDs that I received directly at HP, but when I use them, even if they have worked in the past, I thought that the discs do not support my HP model.  I've made several changes to the hardware (for example, replace the graphics card, some CD-Rom drives, additional memory, along with other things).  Cancellation and so restore the material to the original state of the computer will CDs recognizes the HP model once more?

  Thank you very much!

  UPDATE: I tried to return the PC to its original state by removing the extra material and restore that which has been deleted.  We had another similar model of HP with similar CD - RW, CD - R and DVD - ROM drives, so I'm only 95% some that I replaced those that actually are came with this PC.  It would make a difference?  The result is that the recovery disks, which are legitimately HP, not home-made copies, and which were used successfully in the past in this same model, has not recognized the model of PC than they were designed for, even if they are a match.  This may be the cause?  And what can I do about it?  My backup files can be done quickly and efficiently, if I don't mind having to do something eventually destructive, as long as I get those recovery CD to do their job.  It is essential that I restore the PC to its factory condition.

  Thank you!

  Hello Taran_Wanderer,

  Unfortunately there is little that can be done on the side Microsoft.  It's HP to provide you with the disks appropriate for your machine model.

  You can look in an update of the BIOS from HP, but honestly, I don't know if this will have an effect on the question of whether or not the HP recovery disks will work.

  Best regards

• Minimizing the differences between the print document page numbers and page numbers fixed ePub format

  Hi all!

  I'm currently involved in a project of ePub format fixed relatively simple. I almost completely finished with the file, but I see for export, only the page numbers in the table of contents for navigation begin numbering at a point different than the print document.

  I certainly don't expect the software ideally know exactly where I want the numbering to start, but I was wondering: is there a way to change the starting point of the navigation table of contents so that I can select the starting point? Here's a screenshot of the situation I describe, taken on my iPad mini using iBooks. A fix for InDesign would be useful, I am very willing to modify the code. Please let me know what additional information can help.

  Thank you very much

  Jacob

  

  I don't have a good answer for you on that I've been unable to get this works as is suspected.

  The next update will include support for a list of the fixed layout pages and to my surprise that it was unsuccessful in the evolution of the Navigation table of contents page (right) numeric values that you see.

  Those who seem to come from literally the index of the XHTML file where is the target of the table of contents. If iBooks is unable to find the target it displays the entry under '... ».

  Where the list of pages seems to make a difference on the iOS7/iBooks, is when you're scouring the pages in display mode page it will display the value of the entry in the list of pages... which is now generated from the string of InDesign page number in a gray oval.

  Maybe this has changed to iOS8/iBooks or perhaps other readers it manage differently - I never had the chance to try it on other players.

• Difference between the Expression SQL and PL/SQL Expression

  Hello
  
  I use the value of the Pnn_ACTIVE_SECTION variable type to show and hide regions.
  
  Based on similar logic, I also filter or put on condition of validations of fire based on same Pnn_ACTIVE_SECTION and a few other conditions as element value is null or not null.
  
  What is the best way to filter.
  
  I used [item = value] option earlier and after a few lights, now I use SQL EXPRESSION that according to me is not otherwise effective than PL/SQL EXPRESSION.
  
  Is this correct? Or who make no difference on the performance of application? I have at least 7 forms and about 100 postings by form (especially the function that returns the error text for the club of multiple postings on the same point in a validation)
  
  Based on the reviews of the forum, I'll turn in my application.

  Does not say that at all. It says that they are different and use another language (SQL or PL/SQL). It is not about performance.

  My first post is yet - maybe you should reread.

  See you soon
