• Determine the number of channels selected for traditional DAQ

  The blocks 'DAQmx task' and "Traditional DAQ Channel" look pretty similar (see attachments). The DAQmx block ist an individual selection of channels and I am able to determine the number of selected channels.

  Now I am trying to determine the number of selected channels to a traditional DAQ, but the property DAQmx block does not work here. I already tried the trad to some form of blocks. Range of data acquisition, but failed.

  Any idea?

  

  In traditional DAQ, there are several ways of specifying the list of channels. Assuming that your picture shows how you use your channel list is just a string of delimited by commas. Wire a constant to a string array node worksheet and specify "comma" as the separator and the number of columns must tell you the number of channels.

• How to use NIDAQmx to determine the number of lines correlated DIO?

  How can I used NIDAQmx to determine the number of correlated DIO lines that supports a device?  For example, the NI6225 supports 8 correlated digital of/s lines while the NI6229 supports 16 correlated digital of/s lines.  How can I used NIDAQmx to determine the NI6225 supports only 8 lines while the NI6229 supports 16 lines?

  I moved this question from a previous thread.

• How can I determine the type of image to be used before loading an image?

  I'm developing an application using VB 2005 which measures two 8-bit or 16-bit image files. When I saw the picture, I find that I have to set the type of image the image buffer before playback of the image in it. For example, if I read a 16-bit image in a buffer of 8 bits, the image is truncated. I guess I could read the image in a 16-bit buffer and retype it if the pixel values are less than 255.

  Is there a better way to do it? Can I determine the number of bits of an image before loading in a buffer?

  Thank you!

  Hi Steverino,

  Olivia is incorrect... VDM has a function called GetFileInfo which does just what you want. It only reads the header of the image but does not load the entire image in memory. It will give you various properties such as the bit depth.

  I think that on the new .NET support, there can exist here: NationalInstruments.Vision.Analysis.Algorithms.GetFileInformation.

  Thanks to the ICB and our legacy of .NET support, it's probably a similar name.

• How to determine the number of pixels of an object in a digital photograph?

  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

  I just saw your second message. Thanks for posting this; It may be useful to see your code, even if this does not work.
  It sounds like you have the CONNECT BY part properly, but you do a lot of difficult operations on dates. Oracle provides several very useful date manipulation functions, as well as the DATE arithmentic. Beware of excessive conversion of DATE in VARCHAR2, or vice versa. For example

  to_char(to_date(...
  

  It almost never be in Oracle.

  Hello, welcome to the forums.

  Something like this should do it:

  with day_tab as (
  select mon_dt + level - 1 dt,
         to_char(mon_dt + level - 1, 'DY', 'NLS_DATE_LANGUAGE=''ENGLISH''') dy
    from (select trunc(to_date(m || '/' || a, 'MM/YYYY'), 'MM') mon_dt
            from (select &v_month m, &v_year a from dual))
  connect by mon_dt + level - 1 <= last_day(mon_dt))
  select count(*) cnt_tot
    from day_tab
   where dy in ('MON', 'TUE', 'WED', 'THU');
  

  Run the example:

  SQL> var v_month number
  SQL> var v_year number
  SQL> exec :v_month := 2;
  
  PL/SQL procedure successfully completed
  v_month
  ---------
  2
  
  SQL> exec :v_year := 2000;
  
  PL/SQL procedure successfully completed
  v_year

    2  select mon_dt + level - 1 dt,
    3         to_char(mon_dt + level - 1, 'DY', 'NLS_DATE_LANGUAGE=''ENGLISH''') dy
    4    from (select trunc(to_date(m || '/' || a, 'MM/YYYY'), 'MM') mon_dt
    5            from (select :v_month m, :v_year a from dual))
    6  connect by mon_dt + level - 1 <= last_day(mon_dt))
    7  select count(*) cnt_tot
    8    from day_tab

  v_year

  If by chance you want to see a number of days of the week just to use a group of:

  SQL> with day_tab as (
    2  select mon_dt + level - 1 dt,
    3         to_char(mon_dt + level - 1, 'DY', 'NLS_DATE_LANGUAGE=''ENGLISH''') dy

• Determine the number of rows returned by a cursor

  I have a problem when I need to use slightly different logic based on whether or not a cursor returns a single line or multiple lines. I know you can use % ROWCOUNT to determine the number of rows returned far+, but it's not really help me because I need to know this information before I start to do any treatment.
  
  
  In other words. How can I know the number of rows returned by a cursor without actually iterate through the entire thing.
  
  I'm looking for something like this:
  

     Cursor ReqCursor(pi_cert_id IN Varchar2) Is
        SELECT course_id cid, grade g
          FROM requirements
         WHERE cert_id = pi_cert_id;
     c_ReqCursor ReqCursor%Rowtype;
  
  Open CertCursor(p_cert_num);
      Loop
          Fetch CertCursor
            INTO c_CertCursor;
          Exit When CertCursor%Notfound;
          
          If c_CertCursor%NumOfRows > 1 THEN
              Case A;
          Else
              Case B;
          End If 
     End Loop
  Close CertCursor;

  For your business add

   SELECT course_id cid, grade g, count(*) over() Tot_Rows
          FROM requirements
         WHERE cert_id = pi_cert_id;
  --"Fetch 1st row and you will know if the cursor has more than 1 row"
