• LabVIEW data into a text file

  I have a LV program to save the LabVIEW data into a text file. The LV file is attached. My problem is: the first data that are saved after the headers of data, is on the first line of the text rather than the second file. Ideally, it should be line 1, line 2 from data headers. I don't know what is the origin of the data to be concatenated with the headers. Can anyone help on this please.

  Thank you and thank you for your time in advance.

  Hello!

  Your problem seems to be quite simple, if I understand it right.

  All you need is a constant to be concatenated with your header line end.
  The end of the constant line is equal to CRLF.

  So, if you concatenate the header with the CRLF, your concatenated string will be like: "header \n".

  and then, in the following lines (1, 2, 3...) your data will be available as it was already.

  I enclose a snapshot with this change.

  I hope that solves your problem!

  Best regards.

• How to save the data to the new file, when you press the button

  Hello.

  Run a program that reads data recorders seconds and displays a trace on the screen.

  What I want, is that when I press a button, the program will ask for a file name and begins to record data to the file, and continues to do this as long as the button is pressed.

  When I press the button again, the program asks the name of the file again, so I can select a new file to write.

  I've included a simplified version of my program that works by asking the file name at the beginning.

  How can I change the program it starts a new file every time that the key again.

  Kai,

  I changed the example that I gave you to LV8.0, but I have never used the option 'Save for the previous version' before, so I don't know if it will work.

  I have combined the start and stop of recording in a single button (just change the text to all what you need) and I used the 'value' property to pass the path between cases. The path can be formatted as you have in your version, don't forget to use the string conversion function filepath.

  Just in case where it doesn't work on your version of LV I've attached a screenshot of the block diagram.

  Hope this helps, let me know if you have more problems with this.

  Easy.

  Darren.

• LOAD CSV DATA INTO A NEW TABLE

  I have a basic csv file-12 columns, 247 lines I tried to import or paste it into a new table and with each try, not all records get downloaded in the new table. Using the "Load Data" tool, I tried text data load, load the worksheet data, by import .csv and copy/paste. I put the records in the order PK ID of the table, I added dummy entries in all fields are null (that is, I added the word "None" for empty fields). But nothing works. I get about half of existing records.
  
  Why?

  The Max Size for VARCHAR2 is 4000. If you have a text which is longer, you must type clob column.

  If you wann download the entire file you need of a blob column you need to implement a uploadscript like this: http://www.dba-oracle.com/t_easy_html_db_file_browse_item.htm

• loading data into a pdf file

  I was using CF7 to query data and load in the pdf file using the blog of Ben Forte XPAAJ java library. It's simple, and it worked very well. Then came CF8 and LiveCycle ES. XPAAJ was free, but is not free of LiveCycle ES. LC ES does much more than load data into a pdf and cost a bit, but it's probably worth the money. Because a small part of the LC ES is the same thing as XPAAJ did, the CF8 upgrade almost completely mask XJAAP. (I got it by the judgment of the CF8, starting from the CF7 app service application service, and then restart the CF8 - I don't want to run like that for a long time).
  I can possibly get into LiveCycle, but for now, no one knows something like XPAAJ that can load the data directly into a pdf file or a file Form Data Format (FDF)?
  Thanks Scott
  

  If by 'data' PDF mean you XMP metadata, so yes: CF8 comes with a version of the iText Java library that includes classes for reading and writing XMP in PDF format. Tag of CFPDF, CF8 uses iText under the hood, but does not yet use all of its features via CFPDF, you can simply call the Java classes directly in order to access iText XMP features.

  Reading and writing XMP examples are given here:
  http://www.Adobe.com/cfusion/webforums/Forum/MessageView.cfm?forumid=1&CATID=7&ThreadId=13 28338

  Check the pdfUtils of Ray Camden CFC on riaForge: it contains a new method of readXMP(). writeXMP() is coming - the code is included in the above thread in any case.

  If you mean that the data of the form rather than XMP data, then iText can do too. Check the iText documentation:
  http://www.1t3xt.info/API/

  Here is a small example of filling out form
  http://www.peabrane.com/2007/3/5/PDF-templates-via-Rails

  and cfSearching (who really knows iText in a context of CF), there is this example, note the use of the iText fdfReader class:

• sampling frequency of acquisition and FIFO on 9205

  Hello

  I'm working on a compactrio for ECG analysis in real time. I'm new to cRIO, so I just followed this example, http://www.ni.com/white-paper/11198/en#toc5. and then I try to raise the rate of acquisition of 5000 count (us) or 200 Hz (all I need). I lost my signal to a kind of noise. Does anyone know what it is? See the photo below.

  500, that's us.

  You have a few suggestions.  Read http://digital.ni.com/public.nsf/allkb/583DDFF1829F51C1862575AA007AC792.  I bet your cRIO CPU is at 100%.  I see that it is in the code example that you accessed, but it's an easy solution.  Instead of the Wait (ms), use the function of waiting since the pallet in real time.  Error buffer 50400 comes from your calendar read FIFO.  The time-out period is 20 years, if you're sampling 1-channel 10000us it takes ideally exactly 20 years to get 20 k samples.  Lack of beating of a clock and you get an error.  You don't overflow the buffer, rather does not fill time.  Change of FIFO above should take care of that.

  Regarding the wrong signals to 10000, you read several channels in the FPGA, but happy to send one to the FIFO?  Ghost images could be a problem at these speeds, since you have no simultaneous global sampling card.  http://digital.ni.com/public.nsf/allkb/73CB0FB296814E2286256FFD00028DDF.

  You can do some programmatic method knots analog sampling if you need to perform a check.  You can also define a master delay between analog channels in the project to help with ghosting. http://zone.NI.com/reference/en-XX/help/370984R-01/criodevicehelp/scan_item_method/

• Export data in a flat file without use of FL

  Hello
  
  I'm looking for options where I can export data into a flat file without using a FL (line Layout) i.e., using only the App Engine.
  
  Please share your experience if you did something like this
  
  Thank you

  A simple way to export any folder (table/view) to a csv gall, is to create a set of lines and loops through all fields of record like below example code

  Local Rowset &RS;
  Local Record &Rec;
  Local File &MYFILE;
  Local string &FileName, &strRecName, &Line, &Seperator, &Value;
  Local number &numRow, &numField;
  
  &FileName = "c:\temp\test.csv";
  &strRecName = "PSOPRDEFN";
  &Seperator = ";";
  
  &RS = CreateRowset(@("Record." | &strRecName));
  &RS.Fill();
  
  &MYFILE = GetFile(&FileName, "W", %FilePath_Absolute);
  
  If &MYFILE.IsOpen Then
  
     For &numRow = 1 To &RS.ActiveRowCount
        &Rec = &RS(&numRow).GetRecord(@("RECORD." | &strRecName));
  
        For &numField = 1 To &Rec.FieldCount
           &Value = String(&Rec.GetField(&numField).Value);
           If &numField = 1 Then
              &Line = &Value;
           Else
              &Line = &Line | &Seperator | &Value;
           End-If;
  
        End-For;
        &MYFILE.WriteLine(&Line);
     End-For;
  
  End-If;
  
  &MYFILE.Close(); 
  

  You can of course create an application for generic class call this piece of code.

  It will be useful.

  Do not complain to me ;) on performance issues

• Read data from the Table and load it into the csv file

  Hello

  I would like to read a table (select * from employees) and load the data into a csv file.

  What methods are available?

  Records will be at high volume.

  Thank you

  If it is to do a lot, use APEX.

  Create a new page with an interactive report based on the SQL code you want. When you go to download Excel, it is actually a CSV file.

  If it is large, you may need to go on the FILE_UTL road.

  If it is only once, use an interface such as SQL tool * or SQL * Developer.

  If it's a learning experience, you must do all three.

• Reading about the digital data into the Scanner, followed of a string

  I am a student, new to Java and will be picking up in the semester at College next.
  
  I did my self-study using online tutorials and noticed that when I do this:
  
  Entrance to the parser = new Scanner (System.in);
  System.out.Print ("enter a number :");
  Try
  {
  double d = input.nextDouble ();
  System.out.println ("the number is:" + d);
  
  System.out.Print ("enter a number :");
  String s = input.nextLine ();
  d = Double.parseDouble (s);
  System.out.println ("the number 2 is:" + d);
  }
  catch the exception here irrelevant code
  
  Reading the data for education String s = input.nextLine (); is ignored. I guess it's because of the character "\n" remains in the buffer, am I right?
  
  My solution would be to put a statement (); input.nextLine before the String s = input.nextLine (); and it works. But it feels inelegant to remove the newline like that. Is there a suitable or more 'recognised the market' best way to do this?

  Yes.

  It is the "standard". I wouldn't be too worried about this, the Scanner also is widely used in the real world as tutorials might make you believe.

• organize data for the tablespace files

  Hi all
  
  I would like to ask you if you have a way to organize a tablespace (especially USERS) using 10 data into 1 single file of data files.
  
  You have a way to reorganize a database during the work day, so the watermark will go down, but without making a copy of storage space?
  
  Thank you for taking my question into consideration.
  
  Concerning

  Hello
  I suppose that, if I understand you correctly as a Remap_tablespace with a Tablespace rename DataPump could help you.
  This,
  (1) create a tablespace again with a single good size in data file to hold your all objects. You may need to calculate the size of the data file.
  (2) export all the objects, or better, the schema itself, of the current storage space, we call it source at this time using data pump.
  (3) using the DP import, import the given in the new tablespace, we call it target with option Remap_tablespace = Source: target.
  (4) once done successfully, drop the tablespace from source.
  (5) and rename the target source.
  You would get a tablespace with a data file and all the objects inside.
