How to read csv Data and save it with no format changes

Hi,
At first I am not used to Diadem.
I want to read in a csv file do some calculation with the data and save the changed data in the same csv file. A file as an example is attached (496888_edit.csv).
Therefore I wrote this lines:
Dim i
Dim Delimiter
Dim FilePath
Dim FileParameters
Delimiter = ";"
Call DataFileLoad(FilePath,"CSV","Load")
' Do some calculations
FileParameters = "<filename>"&FilePath&"</filename>"&"<delimiter>"&Delimiter&"</delimiter>"
Call DataFileSave(FileParameters,"CSV")
After running that lines the csv file is looking like the other attached file (496888_after.csv)
Because of some reasons which I could not explain Diadem is rounding the numbers. I want that both files look the same.
What can I do?
There might be another extension. Just to read in some columns, doing some calculations and after the calculation saving that columns in the file instead of the originals. (The csv files are much bigger like the two examples)
Thanks,
Jens

The only thing that can be changed in writing float64 values using the CSV plugin is the decimal point ('.' or ',').
The format of the doubles is not rounded but the CSV writer only writes the relevant digits.
It is using up to 15 digits which is the resolution of float 64. It would also switch to scintific writing if necessary.
So there is no way to force only 6 digits and filling 0s are left out. So if you just fear that you loose precision that will not happen.
(only the typical problems of epressing a 2 system binary value in a 10 system text string)
If you are interested to have a fix float format the only solution is to write with VBS directly to a file doing formatting on your own, which is slow.

How to read the date and time information of a file by labview

how to read the date and time information of a file by labview? for example, created time and modified time.
Solved!
Go to Solution.

if you need to know the last modification date of file:-
"Functions->File I/O->Advanced File Functions->File/Directory Info.vi"
This vi returns the value of file's last modification date. This is returned as U32 number. To see it in MM/DD/YY format you must create the indicator, right-click on it and select "Format & Precision" item from drop-down menu. Then select "Time and Date" format there.
Thanks as kudos only

how can i read the contents of this textfile and put the data into an ArrayList called ArrayList<Customer> customerList.
i knew that i need two classes, one for CustomerDetails and one for ReadFile.
i have already done the customer class as:
import java.util.Date;
public class Customer
    String Name;
    int CustomerNo;
    String Postcode;
    String teleNo;
    Date lastModified;
    public Customer(String Name, int CustomerNo, String Postcode, String teleNo, Date lastModified)
     assign(Name, CustomerNo, Postcode, teleNo, lastModified);
    public void assign(String Name, int CustomerNo, String Postcode, String teleNo, Date lastModified)
     this.Name=Name;
     this.CustomerNo=CustomerNo;
     this.Postcode=Postcode;

         ", Postcode:"+Postcode+
         ", Telephone No: "+teleNo+
         ", Last Modified Date: "+lastModified;
     return allDetails;
}i just wondering how can i code the ReadFile class?
can anyone help me please. thank you in advance.

thank you for your suggestion, but i have already started to code the readCustomer class using the Scanner.
the code i got so far is:
import java.util.Scanner;
import java.io.*;
public class readCustomer
    public static void main(String[] args)
     readCustomer("Customers.txt");
    public static void readCustomer(String filename)
     try {
         Scanner scanner = new Scanner(new File(filename));
         scanner.useDelimiter(System.getProperty("line.separator"));
         while (scanner.hasNext()) {
          processLine(scanner.next());
         scanner.close();
     } catch (FileNotFoundException e) {
         e.printStackTrace();
    public static void processLine(String line)
     Scanner scanner2 = new Scanner(line);
     scanner2.useDelimiter("\\s*:\\s*");
     String description = scanner2.next();
*// here is where i am struggling. i don't know how to get the information after the : sign*
}i am currently struggling with the processLine method?
also, i am not sure how to group a set of information and put them into the arraylist.
Any hint, please. Thank you.

How to read the data in spectrum analyzer (Anritsu MS2661C) and put it in Excel using Labview

Hi all, I'm new to using the labview, and I have some trouble doing my project using the labview software.
I have been trying to use the spectrum analyzer (Anritsu MS2661C) which connect to computer using the GPIB connection.
I have got the instrument driver which can write and control the instrument using Labview 2010.
and my Question is how do read the data or result from the spectrum analyzer and send it to the microsoft excel?
Do I need to use other software or programming to do this step?
If anyone know how is this done, please let me know.
Regards,
Ery

Hi ery,
In order to send data that you have read in from an instrument to Excel, the most convenient way to do this would be to use our Report Generation Toolkit. The Report Generation Toolkit is a very useful tool that allows you to interface to Microsoft Office software from LabVIEW, including Word and Excel. I am not sure if you are familiar with this, but I have attached a link that explains more about the Report Generation Toolkit below.
Another way would be to use the Write To Spreadsheet File VI. While this will store your data to a spreadsheet data file, it will not allow you to programmatically perform any Excel formatting like the Report Generation Toolkit offers. I have also attached a link to some information on the Write To Spreadsheet VI below.
Also, be sure to check out the Example Finder in LabVIEW for a number of examples on how to write data to a spreadsheet file. From LabVIEW, you can go to Help»Find Examples to launch the Example Finder. From there, you can search for "spreadsheet," which should populate examples for use in different applications. I hope this helps, ery. Please let me know if you have any further questions about these!

How to read saved data in BPC 7 Nw Script Logic

Hi all,
I am trying to write the logic for Price*Quantity Calculation. This logic should be executed whenever user saves the data for either Quantity or Price.
For this i created a Implementation on BADI "UJ_CUSTOM_LOGIC". But i am struck on how to read the data from InfoCube ,Like if user saves "Quantity",logic should read "Price" from the cube and calculate the result, Which is equivalent to GET(------) statement in SQL script Logic. Which method should i call to read the saved data in cube.
Appreciate if someone can help me on this.
Thanks&Regards,
Ashok Kumar.

Hi,
You can use the LOOKUP instruction like:
*LOOKUP RATE

*DIM RATE=ACCOUNT.RATETYPE

How to read multiple files and generate multiple files

What you could do is use "list folder" with *.bin as pattern, and use a FOR loop and iterate over all *.bin files found in a selected folder.
In any case, your code uses some weird constructs and you seem to do way to much. Are you using "continuous run" mode? Don't!
Use a proper state machine instead ot these stalling loops. Why do you need to query the queue after each enqueue? Why do you need a queue at all?

How to get system date and time?

Can someone show me a code on how to get system date and time.
Thanks!

there is one really easy way to get system time, the api gives a great example of code on this. use gregorian calendar, which you'll find in the api under GregorianCalendar. You only need to create one instance of GC, ie Calendar time = new GregorianCalendar();
you save seconds, minute and hours into int values, so you don't have to access the system time every second, you can create a thread which adds one to the int second value, if oyu see what i mean, for example, i have saved the hours, minutes and seconds as int values;
int hour, minute, second;
i can then create a thread (Thread thread = new Thread(this) and run it like:
Calendar time;
int hour, minute, second;
Thread thread = null;
public MyTime() {
hour= time.get(Calendar.HOUR_OF_DAY);
minute = time.get(Calendar.MINUTE);
second = time.get(Calendar.SECOND);
if(thread == null) {
thread = new Thread(this);
thread.start();
public void run() {
Thread t = Thread.currentThread();
while(thread == t) {
thread.sleep(1000);
second++;
if(second > 59)
minute++;
if(minute>59)
hour++;
formatTime();
public void formatTime() {
second = (second > 59? 0 : second);
minute = (minute > 59? 0 : minute);
hour = (hour > 23? 0 : hour);
System.out.println(hour+":"+minute+":"+second);
public static void main(String[] args) {
new MyTime();
I know this looks like gibberish but it should work. If not, try to fix the problem, i have written from memory really but i guarantee you, this gets the time then every second, simply adds one to the second and then formats time. You can also access the day, month and year then format them using the above code. I don't like giving code since you should really do these things yourself but it is 2:04am, i have nothing better to do and i am not tired so i did you a favour - i have become what i always did not want to, someone ho stays upall night writing code.

Read HTML tags and Save Images in web page

I had problem with reading HTML tags and save all images in that page. I can source code in web page but I dont know how to Identifly the image tag ( IMG tag ). I think i want to use string tokenizer class.

But i dont know how to use it in my problem. If any one know how to do it. reply this.If you have a big, long string with HTML content in it you might try splitting on a regex like so:
String html = ...
String[] imgTags = html.split("<img.*?>");[http://java.sun.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)|http://java.sun.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)]
to get your image tag data and then parsing that to get the src attribute. You can either treat this problem as a big string-parsing problem, or getting some HTML DOM library and using that to structure the page as a tree for easier access.
If you want more help you'll have to show the code you have so far. We can't write this for you.

How to read the data in excel sheet

Dear sir,
How to read the data in excel sheet when i recieve a data serial communication... ie i have store a data in excel such that
Cell A Cell B
A Apple
B Ball
C Cat
D Doll
when i recieve A from serial communication i have to display Apple, and when i recieve B i have to display Ball and so on..

Hi,
I would recommend you to have a look at the VI attached. It makes use of a VI named 'Read from Spreadsheet' to read the row and column data from the tab delimited excel file. The read data is then searched for the Alphabet specified and finally returns you the corresponding string. The test file used to validate the operation of the VI is also attached.
Trust this would help you solve the issue.
