• Generate a waveform self-defined by reading an excel file

  Hi all

  Now, I'm generating a waveform of salt-defined by a PXI. Attached is a vi I built for the generation of AC signals, in vi, I used a signal generator to a wave of sinnusoidal of generrate of alternative voltages. I guess I can replace this signal generator with a block that can read an excel file which contains instances of time and their corresponding voltage.

  Can you please tell me if this idea works. If it is, block who can do this job?

  Thank you very much.

  Yes you can.

• Read all LVM files in a folder and compile

  Hello

  I want to read all the LVM files in a folder as shown in Figure 1. In each file LVM, there is a row of data that are important, like on the picture 2. I want to extract only the rank of value in all the files this particular file LVM.

  Then I want to compile in 1 Excel or text file.

  Furthermore, I also want to name each line values in newly compile it files. The name will be the name of the file extracted it previously, as well as the date and the time it was created.

  I tried to use the loop and the folder list, but to no avail.

  Hope that this will not be a too much trouble. Thank you

  Hi pengxin,.

  What room are you stuck at?

  Below is a diagram of simple block that I created which should do what you need. First of all, we get all the names of individual files, and then one by one, we read the data from the file. Since you only need the data in the first row, we will index in the array, add the name of the file, the date and time of last modification of the file to the front of the data, and then save them in a new file.

  

  I hope this helps.

  Kind regards

  Thank you for contacting Microsoft Community.
  Unfortunately, this feature is not available in Windows. The feature is limited to media files only and that the support for multimedia files is available in Windows (such as jpg, mp3, wmv), without any obligation to a third party software must be installed (as for the flv file).

  Could someone help with this request.

  Thanks in advance

  Beginner_X

  Hi BEGINNER_X,

  First of all, you must convert the excel file to the format of files "*.csv or delimited by tabs. (I use commas .csv file).

  You posted in above code JS reading only the names of paragraph style. Then another code is read only comma-delimited text file, but you are not comparing the paragraph style in the list of excel files. You missed here.

  Please try the JS code below his works very well, but not generated the report file. I hope that you will generate the report of your side file.

  var myFile = File.openDialog("Choose a tab delimitted txt file:");
  if (!myFile){
  exit();
  }     
  
  var myArray = []
  myFile.open('r');
  while (myFile.eof==false){
      var line=myFile.readln().split(",");
      myArray.push(line[0]);
      }
  
  var myDoc = app.activeDocument;
  var myPstyles = app.activeDocument.allParagraphStyles;
  
  Array.prototype.contains = function(obj) {
      var i = this.length;
      while (i--) {
          if (this[i] === obj) {
              return true;
          }
      }
      return false;
  }

• How to read an excel file .xls to a forms 6i

  Hello
  I have forms6i and webutil don't works with this version, I can read a forms6i excel file.
  Thank you

  If it's a web application, you might do the following:

  Download the file from the client to the application server, there is a FileUpload-bean in the sample forms.

  Write an ontop of some excel library such as Apache POI-RICH or JExcelApi java program to extract the necessary data.

  Use the importer-Forms-Java (I'm not sure, but it should be already there in forms 6i) to create a PL/SQL-wrapper around the java code. Now you can use pure PL/SQL for reading excel fields and process the results.

• A Palm Desktop allows to load/update a Palm V and Tungsten T2 (separate for each software/data)?

  I have a T2 tungsten used for business (in sync with your desktop XP and laptop XP). I recently got a Palm V I intend to use for personal applications / hobby (a controller requiring a serial connection). 2 devices may not be synchronized - in fact, they need their files and separate applications. The current installed desktop application comes from the T2 Setup disk (V 4.1.4).

  I need to load an older version of Palm Desktop for Palm V of load/install programs?

  How can I load applications Palm v and keep the Palm V files to take charge of the T2 (and now the files synchronization T2 Palm v)?

  DRM for all the advice!

  Hello and welcome to the Community Forums of Palm.

  As long as you keep a separate Hotsync ID for each of the two devices, you should be able to sync the V of the same installation of office.  Create a separate Hotsync ID will also create a folder of device separated on the desk, at which all the separate data and third-party applications will be synchronized.

• LabVIEW can read data Excel with Excel installed Starter?

  I'm reading an Excel file, but I get the error-2147221164 try to read an Excel file and I think it's because of starting Excel. Is this the case?

  You probably found this:

  http://digital.NI.com/public.nsf/allkb/B7F980D169474D568625760E0055D55E?OpenDocument

  Who said Excel is not installed, but I think the problem is that Excel Starter (and the word by the way) is a not the component ActiveX.  This is what is used behind the scenes to talk to Excel, and without it, you will get several errors.

  EDIT: I can't seem to find where it says ActiveX is not included, but I remember having read - it somewhere.  Here is the wiki on this topic page.
