• How to measure the number of pixels involved in a selected area of a digital photo?

  Hello world. I want to determine the number of pixels in an object that is part of a digital photo. I use cameras to film of ice pieces, breaking with tide glaciers or ice cliffs. I want to know the size of the ice segment that capture my digital photos. I know that the width and height of the cliff of ice in metres already, so I thought that I could convert the equivalent of 1 pixel:? m is really what I want to do. This way, whenever I see a block of ice, breakup, I can pull up the photo, describe the piece, calculate how many pixels to fill the area of ice removed by piece break and convert into zone meters 2 - giving me my order of size. If anyone has any ideas on how to do really, I would appreciate it thanks so much community. I thought Photoshop or Fireworks might help me with this, Ricky

  Check out the view > Journal of measures.

  If you have a selection and press 'Measure of recording', you should get the field among others.

  

  Another possible approach would be to the histogram, but I doubt it would be very convenient.

• How to determine the number XP or XP 64-bit operating systems.

  Hello
  I need to download a driver but need to know if I have Windows XP, XP 64. I run Internet 7 SP3 if that makes a difference. Properties-General-he reads the slot system Microsoft Windows XP Home Edition Version 2002 Service Pack 3. I think this answers the question that it is not XP 64 but want to make sure and would appreciate any help.

  XP Home does not come as an x 64 version.

  How to determine whether a computer is running a 32-bit version or the 64 bit version of the Windows operating system. http://support.Microsoft.com/kb/827218

  Windows XP if you have Windows XP, there are two ways to determine if you are running 32-bit or a 64-bit version. If one does not work, try the other.

  1. Click Startand then click run.
  2. Type sysdm.cpl, and then click OK.
  3. Click the general tab. The operating system is displayed as follows:
     • For a 64-bit version operating system: Windows XP Professional x 64 edition Version < year=""> appears under System.
     • For a 32-bit version operating system: Windows XP Professional Version appears under System.

     Note is a placeholder for a year.

  1. Click Startand then click run.
  2. Type winmsd.exe, and then click OK.
  3. When System summary is selected in the navigation pane, search for processor under item in the details pane. Note the value.
     • If the value that corresponds to processor starts with x 86, the computer is running a 32-bit version of Windows.
     • If the value that corresponds to processor starts with ia64 or AMD64, the computer is running a 64-bit version of Windows.

  If you cannot determine the number of bits of the operating system with these methods, go to the "Next steps" section (of the KB article)

  To write value specifies the value to write in the channels, lines or ports selected in string parameters. In other words, this value will be the value of your DC output (for example if you enter 5, your output will be 5V). To get information on different fields in SignalExpress, access help"context-sensitive help. A pane will appear in your work environment that displays the coordinates of the field when you place your pointer over them.

  For new users of SignalExpress:

  Generation of DC signals with NI DAQmx devices: step in the DAQmx build, select 1 sample (on request) in the generation Mode dropdown. You can select a programmatic input to generate, or you can remove the check mark from the check box use programmatic input and specify a value for generating in the field of value to write .

• How to determine the number of records in a subquery

  I am fairly new to Oracle SQL, and would like to know if anyone has examples of how to perform the following operations:

  1. I would return the number of rows that exist in the following SQL statement below. This SQL will be part of a larger SQL statement and I will be passing in the EMPLID identifier in the subquery. The result must be a value showing the total number of records that correspond to the SQL below. "xyz" will be finally passing through the extension number of the employee by using a reference to the parent SQL... ie: jbe. POSITION_NBR
  2. My SQL:

  SELECT Cjbe. EMPLID OF PS_JOB cjbe
  WHERE cjbe. POSITION_NBR = "xyz".
  GROUP BY cjbe. EMPLID

  I would like to know how I can change the value of poarent to POSITION_NBR (I think I use jbe.) POSITION_NBR) total calls the EMPLID found in this subquery subquery and then return.

  Thanks for your help.

  Maybe I lack something, but isn't this just

  SELECT count (distinct empl_id) from ps_job where position_nbr =: some_position_nbr

• How to determine the number of rows in the database and save the result to a local variable?

  Hello

  I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

  I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

  Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

  It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

  -RautSa

  Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

  I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

• How to determine the number of activations

  I have a family Pack of Windows 7 Home Premium 3.  I know I used one of the upgrade on an old XP PC and it introduced until Windows 7, but I had trouble during the process, so I have used two activations.  Is there a way that I can know how many activations I've used or have left?  I wouldn't go through the whole process only to find out that I had left all the activations.

  If this computer dies, the license would automatically be abandoned and be free to be used elsewhere. You should probably use the activation of the phone well.

  How to activate Windows 7 manually (activate by phone)
   
  1) click Start and in the search for box type: slui.exe 4
   
  (2) press the ENTER"" key.

  (6) explain your problem clearly to the support person.

• determine the number of pages of a pdf prior to any operation on it

  Any of you know how to determine the number of pages in the pdf file (selected with the Open for example)?

  Somehow, I can't understand how to do that any way short of actually opening/pixelation all pages without prior knowledge of the actual number.

  I would like to use this information to determine the number of items to a contact-sheet-like procedure beforehand.
