• Read xls file and display the data in the table.

  Hello

  Try to read the data from an xls or csv file and fill the same data in the table. If I need to use the table to store the data from the file and display, hoping that someone could help.

  Thank you

  Hi hari,.

  One thing that is very important when you use the Excel activeX interface (in case you need it) is good termination of worksheet/workbook/lettering handles.

  You need these handles to specify what cell in which file you are trying to access.

  If you are unable to throw each handle you have, then you will be left with ghost Excel process in your task manager, devours your system's memory.

  Thus, when debugging of your application, open the Task Manager and the watch as Excel treats created/destroyed and make sure that you end up with zero Excel process running when your application is closed.

  Also consider the case of fault for your program. Check that your exit routes did not omit any termination of handle.

• Is there a way to select an area of some of the elements of a csv file and read in LabVIEW?

  Hello everyone, I was wondering if there was a way to select only a certain "box" of the elements of a .csv file in LabVIEW? I have LabVIEW 2011 and my main goal is to take two tables and graphs against each other. I can import the .csv perfectly and separate each line and each column to be his own, but I have a 8 X 8 but want graphic in the middle of 4 X 5 or something like that. Is it possible to extract a table without starting at the beginning and end in the end? Thank you in advance.

  Hi Szklanam,

  as a CSV file is a TXT file with a different suffix, you can read a number of lines in this file. For example, you can limit the number of rows in your table of resultung. To limit the number of columns, you must always use an ArraySubset, so maybe it is much easier to read the complete CSV file and select interesting places with ArraySubset...

• ODI - read CSV file and write to the Oracle table

  Hello world

  After 4 years, I started to work again with ODI, and I'm completely lost.

  I need help, I don't know what to use for each step, interfaces, variables, procedures...

  What I have to do is the following:

  (1) reading a CSV file-> I have the topologies and the model defined

  (2) assess whether there is a field of this CSV file in TABLE A-> who do not exist in the table is ignored (I tried with an interface joining the csv with the TABLE model a model and recording the result in a temporary data store)

  Evaluate 3) I need to update TABLE C and if not I need to INSERT if another field that CSV exists in TABLE B-> if there

  Could someone help me with what use?

  Thanks in advance

  Hi how are you?

  You must:

  Create an interface with the CSV template in the source and a RDBM table in the target (I'll assume you are using Oracle). Any type of filter or the transformation must be defined to be run in the stadium. (you must use a LKM for SQL file and add an IKM Sql control (it is best to trim them and insert the data when it cames to a file if you want after this process, you may have an incremental update to maintain history or something like that).)

  

  For validation, you will use a reference constraints in the model of the oracle table: (for this you need a CKM Oracle to check constraints)

  

  Then, you must select the table that you sponsor and in the column, you choose which column you will match.

  

  

  To article 3, you repeat the above process.

  And that's all. Pretty easy. If you do not have the two tables that you need to use your validation that you need to load before loading the CSV file you need valid.

  Hope this can help you

• I have the latest downloadable version of the LR5.  It crashed while it was perceived 1:1 uttered during an import. After a restart of the Win764(), it displays a message that LR has to leave because he cannot read the preview files and it will try to fix

  I have the latest downloadable version of the LR5.  It crashed while it was perceived 1:1 uttered during an import. After a restart of the Win764(), it shows a message that LR has to leave because he cannot read the preview files and it will try to fix it the next time's lance.  I get the same message to another and whenever he throws so I can't launch LR at all now.

  I get the preview of a file has been corrupted somehow.  Is it possible to fix this without having to build a new catalog?

  Use Windows Explorer to open the folder containing your catalog. You will see a folder with the extension .lrdata. You must remove this folder, and then restart the Lightroom. Lightroom will generate a new folder of previews.

• How about you, the personalization feature in reading a csv file?

  I want to know about the personalization feature and how to implement it in j2me blackberry for reading a csv file

  So guys someone help me about this

  It is a code that I found somewhere that will provide this type of functionality.

  It uses % and $ to indicate where substitutions must go, and the number between the two is used as the index in the array of strings that you provide as the second parameter.

  I suspect that you can adapt it to your needs.

  As Simon points out, it's really just a problem of standard Java, and you will be able to find solutions to these kinds of things looking around the Internet rather than here, where our attention is BlackBerry Java.    in fact, I think I found this code somewhere on the Net.

• Anyone has any experience of importing a csv file and store it in a database in MS SQL

  Anyone has any experience of importing a csv file and store it in a database MS SQL. Outside sql injection there is any another converns security?

  Draft of the steps.

  1. use to download the file from the client to the server see
  http://www.dennismiller.TV/index.cfm/2007/12/26/file-upload-using-ColdFusion-and-Flex

  2. use to read the contents of the file into a variable.

  3. perform a loop on the content of variables for each line, dealing with the variable as a list delimited by a newline rather then a comma

  4. use list functions on each line to get the data you need, and then to transmit these data to SQL with CFQUERY or CFPROCPARAM.

• Create a csv file and send it in an e-mail message

  In coldfusion, is it possible to create a csv file and send it in an e-mail, without ever save this file on the hard drive?

  Lol you can't attach a file to an e-mail, unless the file has been created.

  We deal with this situation by creating the file in a directory designated for dynamically created files.  Then we have a scheduled task that cleans all files over a certain age, every night.

• Load a CSV file and access to variables

  Hi guys,.

  I am new to AS3 and treated with AS2 before (just to get the scope when change it).

  Is it possible in AS3 to load an excel .csv file into Flash using the URLLoader (or?) and the data in the form of variables?

  I can get the .csv to load and trace values (cell1, cell2, cell3...) but I do not know how to collect the data and place it into variables.

  Can I create a table and access like so... MonTableau [0], myArray [1]? If so, I don't know why it does not work.

  I have to be on the road quite wrong. Here's what I have so far...

  var loader: URLLoader = new URLLoader();
  loader.dataFormat = pouvez;
  loader.addEventListener (Event.COMPLETE, dataLoaded);

  var request: URLRequest = new URLRequest ("population.csv");
  Loader.Load (request);
  //...
  function dataLoaded(evt:Event):void {}
  var myData:Array = new Array (loader.data);
  trace (mydata [i]);

  }

  Thanks for any help,

  Sky

  Simply load your csv file and use the string flash methods to allocate these values in a table:

  var myDate:Array = loader.data.split(",");

• FileToArray or readline to read a file and displays the information in a textbox control

  CVI, I am a beginner and I have a few basic questions.
  I am currently using CVI 2009th

  I want to open a file and transform it into another format. The most important information to be included on the GUI.

  The text display, I use the text box.

  With readline, everything has worked, but for my rows of data is rather impractical.

  That's why I tried the same thing with FileToArray. But the table does not appear in the text box.

  I don't know exactly how works the text box. Is - that the textbox is a page break after a certain number of characters? Or I can write a text in succession away?

  Here are a few lines of my code.

  FileToArray
  FileToArray (road access, & fcsLine, VAL_CHAR, fcsfile_numberofelements, 1, VAL_GROUPS_TOGETHER, VAL_GROUPS_AS_ROWS, VAL_ASCII);
  What is the proper way to display text with filetoarray?
  SetCtrlVal (tabPanelINFO, TABINFO_FCS_VERSION, fcsLine);
  InsertTextBoxLine (tabPanelFCS, TABFCS_FCSBOX,-1, fcsLine);
  ReadLine
  While ((fcsfile_open, fcsLine, fcsfile_numberofelements) ReadLine > = 0)
  	{
  InsertTextBoxLine (tabPanelFCS, TABFCS_FCSBOX,-1, fcsLine);
  }
  

  OK I found documentation on the format of your data, and it seems at the first glance not so difficult to decode.

  A few answers to your questions:

  1. opening a file in ASCII mode allows the system to recognize and welcome the correct new line character (the one that allows to ReadLine to interrupt playback) sequence. As you treat binary data may be ASCII option is not the best, you can use

  2. using a data structure or by analysing the single lines in significant variables is somewhat equivalent: in my opinion, the structure is more immediate, she may not need any extra data setting to use correct variables populated by vales (depends on data format and packaging data: little - endian or big-endian and so on)

  3. as much as I've seen in the part of the file that you have posted, the hexadecimal bytes you observe are not in the file: they are only a means of your Viewer uses to represent unprintable binary data

• How to store characters in result file and display on front panel

  Hello

  currently I am working on the FPGA project.i want data acquired from FPGA board.i want to know on how to store characters to the file and contineous each character display on the façade in the string format.

  I'm full up to characters on the front display, but display characters only when I want all characters in string format.

• Reading a text file and store it in a table, guard return 0.

  Hello, I have an application where I need to read the speed and rate of a text file. For this application, I use a myRIO NEITHER and I want to save the text file on the drive the myRIO aboard in the tmp folder. I simplified my request to isolate the possible problem and I will attach a sample text file and my VI is used.

  Overview:

  I use a myRIO project because in my real application I myRIO VI of PWM and encoder. I noticed that my problem goes away when just open the main VI and run the application in LabView. My problem then that chairs the VI on a project myRIO folder.

  To address the issue:

  My question is, when running the VI of the hand of a project myRIO folder everything works as it is supposed to, but when you open the text file in my Subvi, it returns 0, as if nothing is in the text file. Now if I open the VI outside myRIO se project file it works just assumed that when X = 1, it opens the text file written data in a table and then close the text file. I can't understand why he reads nothing in the text file executing the main VI of a project of myRIO and when I use run to highlight one can see it opens the text file and then returns nothing. The text "test" file must be placed in the tmp folder on board the myRIO to validate my way.

  Is there a way to fix this?

  I assume because I use a myRIO project I can't access the file text, or because of how LabView?

  Any help is appreciated, thanks in advance!

  You don't have your son wired error upward.  You're files showing error functions?

  What context are you running VI when you are within the project and what context from outside the project?

  My suspicion is that in one case, you run on your PC, the other on the cRIO.  Your file exists only on one device or the other.  And also that when you change your PC for the cRIO, your file path must change.  It's very strange that your watch VI access you the disk R:\.  I bet that the R:\ car n does not exist on your cRIO.
