• How to create impulses cause a pulse width Variable AND at the same time

  Hi all

  I have a NI PCI-6251 that comes with 2 counters, a FREQOUT port and then some DIO, DAC and ADC.  I want to trigger a pulse of variable width (easy to do with two counters) and a frequency closed, exit at the same time.  So, I want to end up with a line that will display TOP for some variable time, while the other exits a train of pulses for a time variable.  It is easy to do if you have 4 counters but I don't have one.  Does anyone have an idea to implement these two things AND making them trigger at the same time with the PCI-6251 card?

  The line is high for as long as your pulse train controlled?

  If so, set up the first counter as output pulse, configure the 2nd as output continuous meter but with the internal of the first counter output as its trigger to pause (pause when it is low).  Start the 2nd meter before the first.

  If not, you will need to use the digital output to replace at least one of the counters (max sampling rate is 10 MHz, so this would give less resolution compared to the time base of 80 MHz counters).  So you would simply write the waveform predetermined in the buffer and he clock at the desired rate and the number of samples to give the signal that you want.  You need to generate some other subsystem as FreqOut clock.

• [Oracle 8i] How to convert a string (timestamp) in a date?

  I find it difficult to know how to convert a string to a date time stamp (or possibly several).
  
  The timestamp is 20 positions, character (NOT NULL, CHAR (20))
  in the format: YYYYMMDDHHMMSSUUUUUU
  where Y = year, M = month, D = day, M = Minutes, S = seconds and U = microseconds
  
  The reason why I want to convert it is so that I can compare a timestamp to each other (that is, I want to be able to find the MIN (timestamp), MAX (timestamp) and make comparisons of inequality).
  
  Is this possible?
  
  Thanks in advance for the help on this!

  Hello

  As Damorgan said, if all you want to do is find which is the earlier or later, then you can just compare the strings: they are in a format where it works.

  If you need to do other things, such as compare to today date or see the difference between two of your lines of days, you will need to convert it to date. (He has no reason to convert them to numbers).

  A new TIMESTAMP data type, which manages the fractions of a second, was introduced in Oracle 9.
  Since you use Oracle 8 (depending on your subject line), or it must be
  (1) ignores the microseconds, or
  (2) use a separate column for microseconds.

  Whatever it is, use TO_DATE to convert the first 14 characters in DATE:

  TO_DATE ( SUBSTR (txt, 1, 14)
          , 'YYYYMMDDHH24MISS'
          )
  

  where txt is your column of type CHAR.
  To convert microseconds to a number (between 0 and 999999):

  TO_NUMBER (SUBSTR (txt, 15))

• How to create variables and store them?

  How to create variables and store them?

  As someone has already said, we need to learn a little more about what you want to do with these variables, but in general, APEX elements are probably what you want. You can create the elements APEX at the request or Page level. Once you define the value of an element, you can reference anywhere else in the application. So if you have an article on page 1 called P1_ENAME, you can reference it on page 32 using bind variables syntax: P1_ENAME. If you just want to store but not to display certain information, you can use either a hidden page element or an element of Application level. Take a look at day 2 Developers Guide for more information.

• How to convert a string and use a rope as a property?

  I have an array in the following format:

  {ownsCar: 'true', ownsBike: ownsHouse 'false',: 'true'}

  etc ............

  And I need to test against each element, for example

  If...

  How to convert the string (for example, "ownsCar") in a property "myProperty"?

  OK, if I got this right what you need to do is introspection.

  The easiest way to do this would be:

  for ( var propertyName:String in myObject ) {
       // Do what you need with this here:
       myObject[ propertyName ];
  }
  

• Please help, convert this string to a number format

  I send orders via RS232 to my machine and the machine sent back with a display of the number "40" in display normal in my image attatched. I tried to use the string conversion to digital tools, but there is nothing happen just '0 '.

  I wondered with it, then I try output string in a different way as in attached code, display and hex display and see the format of it.

  I want to get the string '40' to take the number, how can I get it? Help, please

  

  Thank you in advance.

  It has worked well for me. Just to be on the safe side, you can use the Trim function spaces (channels palette) to clear the characters "\".

• How to convert a string to byte array

  Hello

  I want to convert a string with a hexadecimal number in the array of bytes, this string includes a cutting-edge information, but I don't want to add this tip to arry bytes.

  detailed information please see the photo. I hope someone can give me some instructions, thank you very much.

  

  The accepted solution of Giedrius.S is not correct, based on the image shown in the first post. That the solution will not eliminate the spaces before the tip, and the string to byte array to convert individual characters '0', '8', 'space', '9', etc. for them to byte values. The right solution, based on the image below:

  

• How to convert a string to a percentage?

  I'm new with Actionscript, but I do a Stress Test and I got to the point where I need to convert this final value (score) to a percentage. The maximum they can get is 35.

  scoreText is the name of the instance that I have used for their score which is a dynamic text

  I was thinking about something like that, but I could be totally wrong:

  function scoreToPercentage(evt:Event) {}

  var scoreText = Number (scoreText);

  var percent: Number = scoreText * 100;

  var roundedPercentage:Number = Math.round (percentage);

  var percentAsString:String = roundedPercentage + '% ';

  }

  Thanks for any help.

  Wait so much worse, I finally did!

  Here's the code I used:

  function updateScore(evt:Event) {}

  round var = Math.round(score / 35 * 100)/1

  scoreText.text = String (round + '%');

  }

  stage.addEventListener (Event.ENTER_FRAME, updateScore);

  I gave up and you just use an event listener. But thanks anyway for tons for the help!

• How to convert a string literal function function valid

  Hello
  
  I have a situation where I need to get the built-in (sysdate/sysdate-1/sysdate-2) as variables. As the variable is taken as a string, it is considered as a string, not a function. Is it possible to convert the string literal in valid function.
  
  Here is an example for better understanding. I used v_var to store the 'sysdate-1 "in the form of string literal. Try to change the value.
  
  
  */*-------------------------------------------------------------------------------------*/*
  declare
  
  v_var varchar2 (20): = ' sysdate-1';
  date of v_var2;
  
  Start
  
  Select v_var in the double v_var2;
  
  dbms_output.put_line ('v_var2: ' | v_var2);
  
  end;
  
  */*-------------------------------------------------------------------------------------*/*
  
  
  Thanks in advance

  Or
