• Take the time between two values

  Hi people,

  I have a problem and I know idea how to solve... I need help.

  The problem is I want to take the time between two values max as you can see in the chart.

  For example, in the image that I have add

  4.5 - 1 840 = 2.66

  And enter this value in the 'time between mostra '.

  It's that I want...

  But what I think is very complicated, because I don't know how to take the time correctly and does remove...

  Thank you very much

  Any solution?

  Hi jocuma,

  I tried something and hope that helps u.

  Just create two arrays of temperature and voltage. First of all, I'll get the value of the voltage when it is more of a certain value and that same index to get the value of time and store in the shift register.

  When I get the second higher than the limit value, I'll get time and subtract the previous value.

• Count the number of records between two values of keys (BTREE)

  How can I count the number of keys between two values?

  I use python driver and BTREE access method.

  = >

  Ideally, what I want is a set of whole time series data (intervals may change) to a given number of points on average. The keys are timestamps and the values are the data that it takes on average. I need to count the number of records between two timestamps so that I can divide this figure by the number of points I need and data on average. What is the best way to do it?  Or should I keep the timestamp constant intervals and use the RECNO access method?

  Thank you
  (first post btw... and why is there not a lot of people at stackoverflow that answering the questions of Berkeley DB?)

  BDB is an integrated db and there no internal counters or statistics you might grap to use for this.    You will have to do it manually.

  You can create a cursor, grap the records you want, whenever you get the next card that you bump a counter.

  If you are using RECNO, you can use a slider to obtain the number of registration (DB_GET_RECNO), and if all that you data is in

  sequentail records with no missing documents, you can find the total number of take the last rec #-original rec # + 1 to get a count.

  If you pass the SQL API, you can issue a SQL query to give you a count.  Select count (*) where...

  As you enter the data anyway, so better perhaps to count records as you go along.

  Thank you

• Delay between two operations in the same visa write buffer

  Hello

  I'm new to labview and have tried to find a way to introduce some delay in milliseconds between two operations in the same buffer of writing a block of single entry visa. Here's what I want it to be like:

  CURR: LEV 1.5

  wait about 50 ms

  CURR: LEV 2.0

  wait once again

  In fact, I must apply an alternating signal to a coil with a certain frequency through a source of supply of power e3631a Agilent. So if there is another alternative for her, so please let me know.

  Thank you

  Concerning

  Here are two approaches. First being the easiest, simply put a delay between written VISA. The second being a more robust because it allows you to develop a series of commands by simply adding the string array. You might forget the case of the loop if you don't mind the 50mS delay before e first command is sent.

  

• Because between two keyframes with the same position, there is movement?

  Because between two keyframes with the same position, there is movement?

  This would be due to the influence or speed?

  Quick glance:

  1. image: 'x' is 384px

  

  2 image: 'x' is 387px

  

  3. picture: 'x' is 384px

  

  Keyframes to which I refer are selected in the middle.

  

  There is a change in the balance between two key frames that are in the same position, without keyframes between them.

• Enter the external value in the while loop

  Hello, I have the following problem. I am beginner labviewe and I created a simple program to record data and control a laser printer driver. The problem is:

  at the beginning, I'm in the temperature values and current - they must be outside of the loop, because I want to include these start values in the header file that I add the file initially.

  Then I go into the loop, but if the control is on the outside I can't change the value more.

  So here's the question: what to do to be always able to change these settings without creating more control?

  Sorry for the mess in VI, but I'm just getting started.

  Thank you very much

  Maciek

  Hello

  A quick solution, create a local variable for the control to use in the loop. Best solution, plan to implement a state machine design model so put everything before the loop in the first State, before moving on to the main report (the stuff currently in your loop). In this way, you would be able to access the control of these two cases which is preferable.

  Hope that helps,

• Adjustment brush works incorrectly between certain values of the brush size

  I am running Windows 7 64 bit on my PC with Lightroom 4.4.  When I resize my adjustment brush cursor by using the wheel of scrolling between certain values the brush cursor changes shape to the usual circular slider for a semicircular slider crushed. Below certain levels, the brush changes from the circular single slider to two small sliders and values less than four small sliders.  Can anyone help. My usual mouse is a Dell USB with scroll wheel and my keyboard is a Microsoft multimedia keyboard.

  I tried the following to any available-

  Re starting lightroom

  Check the BIOS to USB mouse is on

  I've tried different mouse (manufacturers)

  Any suggestion would be appreciated

  Mick Norman

  Hi snowynorman,

  Could you please share a screenshot of your adjustment brush in Lightroom?

  Usually, two circles appear when you have a good pen of value.

  In addition, suggest you try to change the size of the brush manually via the cursor or up and down arrow keys on your keyboard to check if you still see this type of behavior.

  Kind regards

• I'm having a problem with a transition between two clips in the first.

  I put a transition between two clips, but it works only in a single clip. my project is almost done except to fix those errors.

  

  The handles are how you have before and after the section of the video images you removed in the timeline.

  Imagine you put a video in your editing and you use the clip (from the beginning to the end). Then you try and add a second 2 cross dissolve between the shots. First will have to at least 1 second image to prior to the shooting to make the transition, but because that there are no images more to use is unable to dissolve it in the middle of the Cup.

  You can do it all on a track just like FCP of Vegas, but you must have the images it to dissolve in.

• Balance sheet for a YEAR between two dates in the dashboard

  Hello
  
  Could someone help me please how can I calculate the 'balance of the CDA' between two different dates, who is invited to the dashboard? Means: we have an "effective date" and a "prior date" as a promt in the dashboard user who selects dynamically. When displaying in the report, it should show us the "CDA balance" between the two dates selected dynamically by users in the dashbowrd prompt. Please suggest.
  
  Thanking you,
  BK.

  Now that you understand the concept, it is easy to change the constant (i.e., 2011-01-01) to a variable.

  1) start with your repository variable that contains your current date: CURRENT_DATE

  (2) TIMESTAMPADD (SQL_TSI_DAY, DAYOFYEAR (CURRENT_DATE) *-1 + 1, CURRENT_DATE) is the SQL to get the first day of the year.

  Replace the hardcoded hard 01/01/2011 with the SQL above and now it will work for the beginning of the current year. You can change the SQL code for the beginning of a given year.

  Ex. TIMESTAMPADD (SQL_TSI_YEAR-1, TIMESTAMPADD (SQL_TSI_DAY, DAYOFYEAR (CURRENT_DATE) *-1 + 1, CURRENT_DATE)) you will get the start of "last year." This should help you with your problem.

  Now that you have everything, please mark the appropriate messages 'useful' and 'proper' and then mark the thread as answered and others if you are looking for a similar solution can easily find the answer. Thanks and good luck!

  Members of the forum good day!
  
  I'm hoping to get help with and model RTF I use to sum up the output of a query in PeopleSoft.
  
  I have a line with two fields of the query and a third field calculates a percentage using the query fields:
  Row1, Field1: EXPR14_14
  Row1, Field2: EXPR1_1
  Row1, Field3: <? xdofx: If EXPR1_1 <>0 and EXPR14_14 0 then (EXPR1_1 DIV EXPR14_14) <>* 100 or 0 end if? >
  
  I have a second row who has these fields:
  Row2, Field1: <? sum (EXPR14_14)? >
  Row2, Field2: <? sum (EXPR1_1)? >
  Row3, Field3: I need the third field to calculate the percentage of sum of two fields.
  
  I tried different ways to insert this calculation with no luck. It's my first time to create a rtf report and any help would be gratly appreciated.
  
  In advanced thank you for your help.

  For the calculation of percentage you can use something similar to this (adjust the formula you need)

• How to find the difference between two dates in the presentation layer

  Hi Navin,

  TIMESTAMPDIFF function first determines the timestamp component that corresponds to the specified interval setting. For example, SQL_TSI_DAY corresponds to the day component and SQL_TSI_MONTH corresponds to the component "month".

  If you want to display the difference between two dates in days using SQL_TSI_DAY, unlike butterflies SQL_TSI_MONTH and so on...

  hope you understand...

  Award points and to close the debate, if your question is answered.

  See you soon,.

• How to exchange the two values in the same column by using the UPDATE?

  Hi all
  
  I have a table named TEST, and it has a column called A.
  
  and has values as follows:
  
  A
  ------
  10
  20
  30
  40
  50
  
  My question is how to move '10' instead of '20' and '20' instead of '10' in the column? This permutation is only for the first two values (10, 20)
  
  Note: Must be only in SQL, not in PLSQL.
  
  Any advice?
  
  Thanks in advance?

  Update
  test
  the value a = decode(a,10,20,20,10,a);

• Calculations between two time fields

  Hello

  I have a form with a time for the start time field and a text field for the user to enter a duration (for example, 00:30:00).

  There is another field for the end of time (which has a calculation script using the date and starting time fields).

  The script that was placed in the end time field works except the script gives a negative result.

  For example the start time field is 16:03:33 and 00:30:00 duration field calculation end is showing time field-

  Please can someone advise how I can change the script of the time field end to show the correct result of 16:33 (without the negative)?

  
  create string for the current date
  var oToday = new Date();
  sToday var = util.printd ("yyyy/mm/dd", oToday);

  get the value of the start time field

  var sStart = this.getField("Action_Start_Time").value;

  create the JavaScript date object time for start time
  var start = util.scand ("yyyy/mm/dd hh: mm:", sToday + sStart);

  
  get the duration value

  Send var = this.getField("Action_Time").value;

  create a JavaScript date object time to end time
  oEnd var = util.scand ("yyyy/mm/dd hh: mm", sToday + shipment);

  calculate the difference in hours, the difference in hours
  var DiffHours = (oEnd.valueOf () - oStart.valueOf (()) / 1000 / 60 / 60;
  Event.Value = Math.floor (DiffHours) + ': ' + util.printf ("%,302.0f", (((DiffHours % 1) * 60) .toFixed (()));

  Any help will be greatly appreciated.

  You cannot change the '-' operator operator '+' being Modulo calculation date and time calculations. You must calculate the different parts of the date and time of the start time and elapsed time and then convert these values into a date object time and format of this new date time object.

  Clear the field
  Event.Value = "";
  getting the activity start time
  var sEventStart = this.getField("Activity_Start_Time").value;
  calculate only if there is a start time
  If (sEventStart! = "") {}
  operations of the console are for debugging and illustration
  /*
  Console.Show ();
  Console.clear();
  */
  convert a date object change if necessary format
  var oEventStart = util.scand ("YYYY, mm, DD, HH", nNowYear + "," + (nNowMonth + 1) + ',' + nNowDate + ', ' + sEventStart);
  Console.println ("oEventStart:" + oEventStart);

  get the date current time
  var oNow = new Date();
  Console.println ("oNow:" + oNow);
  get the date parts
  var nNowYear = oNow.getFullYear ();
  var nNowMonth = oNow.getMonth ();
  var nNowDate = oNow.getDate ();
  /*
  Console.println ("nNowYear:" + nNowYear);
  Console.println ("nNowMonth:" + nNowMonth);
  Console.println ("nNowDate:" + nNowDate);
  */
  get the duration of activity
  var sEventDuration = this.getField('Event_Duration').value;
  If no entry in force at time zero
  if(sEventDuration == '') sEventDuration = "00:00:00 ';
  convert the time in hours and minutes
  var aEventDuration = sEventDuration.split(":");
  /*
  Console.println (' hours - aEventDuration [0]: "+ aEventDuration [0]");
  Console.println ('Minutes - aEventDuration [1]: "+ aEventDuration [1]");
  Console.println (' hours start: "+ oEventStart.getHours ());
  Console.println ("minutes:" + oEventStart.getMinutes ());
  Console.println ("second Start:" + oEventStart.getSeconds ());
  */
  calculate the minutes and the end times
  var nEndHour = Number (oEventStart.getHours ()) + Number(aEventDuration[0]);
  var nEndMinute = Number (oEventStart.getMinutes ()) + Number(aEventDuration[1]);
  if(aEventDuration.Length == 3)
  var nEndSecond = Number (oEventStart.getSeconds ()) + Number(aEventDuration[2]);
  on the other
  var nEndSecond = Number (oEventStart.getSeconds () + 0;
  /*
