Applying a mathematical operation of string data

• User input to JSON and mathematical operation

  Hello guys,.

  Now, I am currently building another application, and I want to use JSON as my database. There will be multiple entries (entries user, INTEGER) textfield that will be stored in JSON, so I want to apply a mathematical addition on each entry which is recorded in the JSON (total value) database, and then display it in the user interface. I also want to try this with XML, but I don't know if I could do it with XML.

  The sample application in the documentation (registration with JSON data) is not enforced with user input, but we specify the data. There is also an example of a mathematical operation of database. I still don't know the concept and how to write the code.

  Any help would be appreciated. Thank you.

  Hello
  Mathematical operations can be performed in the application itself.

  (1) create input controls, a button that will trigger the operation. Click, calculate the result, update the result field, then record the entries and result in a DB, JSON or XML file.

  (2) when the page is loaded into onCreationCompleted on the Page read handler registered values (if any) and fill the control with data.

  If you need help, please post the code you have so far and that someone may be power help with specific problems.

• Cannot use mathematical operations on the settings defined in the model

  We use BI Publisher 11.1.1.6

  We have a report that contains a few settings entered by the user.  The model defines variables to parameters like this:

  <? param@begin:loadsch;5? >

  I can see the $loadsch parameter in a field very well, using this code in a domain: <? $loadsch? >

  Note that the parameter is given a default value.  When you use the preview function in Word template designer, things work fine.

  The problem arises when a mathematical operation on the variable $loadsch.

  When previewing in Model Builder, I can display a field with the following formula: <? 1 + $loadsch? >

  But, when you view the report on the BI Publisher server, I get very informative typical error: oracle.xdo.XDOException: java.lang.reflect.InvocationTargetException

  Looking at the server logs, I see the following error information:

• What is the HP Digital Imaging Monitor? Apply to my operating system, Windows 7?

  What is the HP Digital Imaging Monitor? Apply to my operating system, Windows 7? I want to remove the icon from the task bar (toolbar in the lower right corner of the screen) that I never use it.

  Picardjc wrote that "Digital imaging monitor is part of the HP software that communicates with your HP printer. This program allows to read the inklevels, get an out of paper message, scan from the device to the computer and so on. It is not necessary, but it will restrict the use of printers if you delete. "Understood. But for my printer HP Officejet Pro 8000 A809a, what is the purpose of having the digital imaging monitor icon in the taskbar Windows7 sp1 of the Notification area (aka system tray)? My A809a is NOT an all-in-one that includes a scanner; It is simply a very good printer. When I start to print something, if you need ink or paper, that information is displayed on the screen of my computer. So I ask again: why is the icon of monitor digital imaging on the taskbar? I clicked on at the time of this icon (I not print anything, but as usual, the printer is turned on), and nothing happened. R.N. (Roger) Folsom _ P.S. below I'll post some other discussions (with links to their locations) of the digital imaging monitor, I discovered before finding this site on which I am writing. There are a variety of opinions on what makes the digital imaging monitor. HP Digital Imaging Monitor is for HP director system tray access. This is necessary if you want to use the buttons of all-in-one on a HP printer all in one to scan documents or transfer photos from a camera manually. Closing the icon monitor HP digital imaging in the Windows system tray can cause the HP all-in-one to lose part of its scanning features and not the connection error message. In this case, you can restore all functionality by restarting the computer or by starting the HP digital imaging monitor.

[Edited] 03/08/2011 14:05 - edited? 03/08/2011 14:08 Yes, it is safe to remove. In my view, it is usually in the program group under start / all programs / startup. Simply navigate under the Start button, right-click on it and delete! If it is not there, then remove it from the registry: run regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and delete it from the list in the right pane. If she is not there, then try hkey_current_user\\software\\microsoft\\windows\\currentversion\\run it's better than using msconfig and uncheck it. In my opinion, msconfig must always be set to Normal startup. Your printer will always print without that annoying obstructive utility called Digital Imaging Monitor. Ciao!

  HI Maria,

  It seems that you are using DIAdem 10.2. In this version, there is a limit to the name of the symbol in block f (x) of 16 characters. If you change the name it works fine (Please take a look at the attachment). This changed with DIAdem 11.0 or later.

  Referring to your second question, I'm not that I really understand the problem. Please can you explain what you would do?

• TDMS replace specific fields with the new string data

  Hello

  Wonder if someone could advise a more easy, more clean solution or I may end up making a big mess on my diagram!

  I use DaqmxConfigureLogging.vi to write data in the .tdms and this file everything works. Unfortunately, this vi affects physical names such as Dev1/ai0 channel names in Journal of root and group of tdms files.

  I would like to read individual fields where they are written and replace them with the names of channel. The location of these channel names is fixed on the tdms file.  However, I noticed using file i/o functions, such as file open/close/set position could not work, because these files do not seem to recognize the .tdms file. And it is not all fields tdms functions you want the value of the positions on sheets of root/channel files tdms and read fields desired as string data.

  Any suggestions? I can miss something quite simple!

  I use Dev1 / ai0:15 connect all 16 channels. Unfortunately if using 'name to assign' entry will not do the job in my case!

  Of course, it will be.  Use a loop FOR with DAQmx channel create to create each channel and give them a name.

  Just to clarify what I meant here...

• ORA-28500 + 'String data, right truncation' when selecting nvarchar (max)

  Hello

  This driver correctly fills the buffer (0 no equal) and function of the buffer the gateway decided to map it to:
  DTY NULL-OK LEN MAXBUFLEN PR/SC CSE IND MOD NAME
  12 Y VARCHAR 20 20 0 / 0 0 0 200 col1
  -1 LONGVARCHAR Y 0 0 0 / 0 0 0 220 col2
  -1 LONGVARCHAR Y 0 0 0 / 0 0 0 220 col3

  and in Oracle when performing a describe statement I see the column as LONG.

  This type of mapping from nvarchar to LONGVARCHAR works in Dg4ODBC if the Oracle DB character set = Unicode. => and you meet this requirement.

• Object string date

  Hello
  Is it possible to convert the string "date (2006, 5, 29) ' in a date object?
  
  Thank you
  Jason

  > Is it possible to convert the string "date (2006, 5, 29) ' in a date object?

  If
  aString = "date (2006, 5, 29).
  then don't
  adate = value (aString)
  do you want?
  Unfortunately, I do not think that the seconds property (very useful)
  remains intact when you convert a date <->leave a string - can you
  give an overview of what you want to achieve? For example, the
  vList xtra can record all the data types of the Director without having to make
  any conversion.

• Formatting: String &gt; Date &gt; String

  This is the best I could do, how to simplify this:
  

  value = new SimpleDateFormat("MMM dd, yyyy  HH:mm:ss").format((java.util.Date)new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(value.toString()));

  NKA says:
  >
  The idea behind exceptions, is that you assume each step will work, and just write the code as if it does. If the method I call returns null instead of throwing an exception on failure, then I have to explicitly check for null at this point, rather than simply move on to the next step. With some exceptions, I know that if I even got to that next step, then nothing was wrong.
  >

  What is this means that the calling code must know that there is an exception thrown from code that was called?

  Well, Yes, if you call a method, and something goes wrong, you want to know about it, right? Catch the exception does not solve anything. All that's happened is always false. You catch an exception because you plan to do something about this.

  What I understand from what you said that the operation should fill in some way by throwing an exception back to the caller, and then, the caller must decide what to do with it.

  Exactly. And often - most of the time, in fact - that the appellant made with it will just continue to throw on top of the stack to its calling.

  What I do is that logs the error in the file and show a popup error message to the user. It works as the operation has not completed, so got canceled due to the outbreak of the exception.

  If you are at a high enough level layer of your code, which may be appropriate. However, I prefer to see this:

  try {
    formatDate();
  }
  catch (SomeException e) {
    showErrorMessageDialog();
  }
  

  than that:

  String s = formatDate();
  if (s == null) {
    showErrorMessageDialog();
  }
