I want to sample syncronously an analog and digital channel and write them to file in array.

I have a PCI-MIO-16XE-10. I am using the AI01 and a DI01 to recieve the signals. I am monitoring and switch and want to know when it comes on in relation to my analog signals when I post process the data so it is important that the signals be synced and placed in the data array. The attatched vi gives some idea of what I want to do. Thank you in advance for help concerning this.

I am using 6221 same issue i have .
i need to accuire pulse of train and its simaltanously triggering the AI.
Issue is while writing this data to an Excel sheet i am missing some data in-between.
number of pulses are 870 , this count i am getting incermentally in the output of Counter
i did "build an array" with this AI and Counter data and writing it to file, there i misses data.
Attached wiring diagram for reference.
Pls suggest some method to write data to file for every pulses so that i wont miss any data.

How to read from one file and write into another file?

Hi,
I am trying to read a File and write into another file.This is the code that i am using.But what happens is last line is only getting written..How to resolve this.the code is as follows,
public String get() {
     FileReader fr;
     try {
          fr = new FileReader(f);
          String str;
          BufferedReader br = new BufferedReader(fr);
          try {
               while((str= br.readLine())!=null){
               generate=str;
          } catch (IOException e1) {

          } }catch (FileNotFoundException e) {
               e.printStackTrace();
     return generate;
where generate is a string declared globally.
how to go about it?
Thanks for your reply in advance

If you want to copy files as fast as possible, without processing them (as the DOS "copy" or the Unix "cp" command), you can try the java.nio.channels package.
import java.nio.*;
import java.nio.channels.*;
import java.io.*;
import java.util.*;
import java.text.*;
class Kopy {
     * @param args [0] = source filename
     *        args [1] = destination filename
    public static void main(String[] args) throws Exception {
        if (args.length != 2) {
            System.err.println ("Syntax: java -cp . Kopy source destination");
            System.exit(1);
        File in = new File(args[0]);
        long fileLength = in.length();
        long t = System.currentTimeMillis();
        FileInputStream fis = new FileInputStream (in);
        FileOutputStream fos = new FileOutputStream (args[1]);
        FileChannel fci = fis.getChannel();
        FileChannel fco = fos.getChannel();
        fco.transferFrom(fci, 0, fileLength);
        fis.close();
        fos.close();
        t = System.currentTimeMillis() - t;
        NumberFormat nf = new DecimalFormat("#,##0.00");
        System.out.print (nf.format(fileLength/1024.0) + "kB copied");
        if (t > 0) {
            System.out.println (" in " + t + "ms: " + nf.format(fileLength / 1.024 / t) + " kB/s");

How do I prevent Adobe from taking my jpegs and making them pdf files? I have had to uninstall Adobe to access my photos as jpegs.

How do I prevent Adobe from taking my jpegs and making them pdf files? I have had to uninstall Adobe to access my photos as jpegs.

I would suggest you change your file associations so that jpgs open in a program other than Acrobat. Assuming you have a Windows machine, just go to the Start, and search for "file associations" ... it's part of the Control Panel.
Scroll down to the file type jpg, and set it to open with whatever graphic preview or editing program you have that you want to use as the default. From that point on, when you click on a jpg, it should not open Acrobat and instantly try to convert it to a pdf.

Read and write a .CSV file contains cirillic characters issue

Hi guys,
I am a developer of a web application project which uses Oracle Fusion Middleware technologies. We use JDeveloper 11.1.1.4.0 as development IDE.
I have a requirement to get a .csv file from WLS to application running machine. I used a downloadActinLinsener in front end .jspx in order to do that.
I use OpenCSV library to read and write .csv files.
Here is my code for read and write the .csv file,
public void dwdFile(FacesContext facesContext, OutputStream out) {
System.out.println("started");
String [] nextLine;
try {
FileInputStream fstream1 = new FileInputStream("Downloads/filetoberead.CSV");
DataInputStream in = new DataInputStream(fstream1);
BufferedReader br = new BufferedReader(new InputStreamReader(in,"UTF-8"));
CSVReader reader = new CSVReader(br,'\n');
//CSVReader reader = new CSVReader(new FileReader("Downloads/ACTIVITY_LOG_22-JAN-13.csv"),'\n');
List<String> list=new ArrayList();
while ((nextLine = reader.readNext()) != null) {
if(nextLine !=null){
for(String s:nextLine){
list.add(s);
System.out.println("list size ; "+list.size());
OutputStreamWriter w = new OutputStreamWriter(out, "UTF-8");
CSVWriter writer = new CSVWriter(w, ',','\u0000');
for(int i=0;i<list.size();i++){
System.out.println("list items"+list.get(i));
String[] entries = list.get(i).split(",");
writer.writeNext(entries);
//System.out.println("list items : "+list.get(i));
writer.close();
} catch (IOException e) {
e.printStackTrace();
say the filetoberead.CSV contains following data,
0,22012013,E,E,ASG,,O-0000,O,0000,100
1,111211,LI,0,TABO,B,M002500003593,,,К /БЭ60072715/,КАРТЕНБАЙ

2,07,Balance Free,161
It reads and writes the numbers and english characters correct. All cirillic characters it prints "?" as follows,
0,22012013,E,E,ASG,,O-0000,O,0000,100
1,111211,LI,0,TABO,B,M002500003593,,,? /??60072715/,?????????

can somone please help me to resolve this problem?

Are you sure that the input file (e.g. "Downloads/filetoberead.CSV") is in UTF-8 character set? You can also check it using some text editor having a view in hex mode. If each Cyrillic character in your input file occupies a single byte (instead of two), then the file is not in UTF-8. Most probably it is in Cyrillic for Windows (CP1251).
If this is the case, you should modify the line
BufferedReader br = new BufferedReader(new InputStreamReader(in,"UTF-8"));toBufferedReader br = new BufferedReader(new InputStreamReader(in,"windows-1251"));Dimitar

I somehow changed a video in my imovie to zero fps, so it just plays black. The video still exists on my desktop but even when I delete the files from imovie and reimport them the file is still in zero fps and play black.

I'm not sure of your question.
Are you asking how to use Photoshop?
Or are you asking for the dimensions of video iMovie uses?
It edits in 720P HD, which is 1280x720.
You can make it a bit bigger so you can zoom in.
Much bigger then this is a waste of time.

Iv lost the files to play audio books iv tried to and found them locate files but that dont work

iv lost the files to play audio books iv tried to and found them locate files but that dont work

I'm going to take a wild guess and say that you have a SATA controlled hard drive. Apparently, there's some kind of bug with SATA disks and Vista and Quicktime/itunes video...and possibly Nvidia is involved as well.
The workaround is sticking the video on a flash drive in order to play it (because that avoids the SATA controller and thus bypasses the issue). It's a crappy workaround, IMO...and I'm not spending another cent on iTunes videos until the issue is actually fixed.

I used "Get Waveform Components" to separate waveform data. I need to get the time stamp and write it on file as an header.

I am not able to solve the problem because I can't find an I/O vi that writes on file time stamp data. An error occurs, because of connecting different data types. How can I convert time stamp data so that I can use it as input in a write on file vi? Please, help me!

The problem with the selection seems to be that you are using two different indexing tunnels on the for loop. One of them loops over every value of the first incoming waveform, the other one over all waveforms in the incoming array. The value you wire to the N terminal will be ignored, the number of loop executions will be the minimum of your indexes. Anyway, the loop doesn't seem to do what you wanted:
- If you want to store the complete waveform: loop over all waveforms, check for the maximum of each of them and write it just like you do now.
- If you want to store only the values of each waveform that actually exceeded the threshold: You can either use 2 nested for loops to iterate over each value of each waveform. Use shift registers t
o create new arrays of timestamps / values for the values you want to store. You need to either convert the waveform to x-y-pairs (VI on analog waveform palette) or calculate your own timestamps. You might as well want to check out the "Search waveform" VI. Configure it so that value+-tolerance covers the band between your expected minimum value and your threshold value. The VI will give you the indices and timestamps of all fits.

How do I read and write to text files on a remote computer's hard drive

I would like to read and write data to a text file on a remote computer. This is easily accomplished using one of the file functions such as "write characters to file.vi". If I am already connected to the remote computer, all I need to do is specify the path to the particular file and it will work fine.
My problem is that I want to connect to the remote computer programatically within LabVIEW (I do not want to have to use the computer's OS to establish the connection. Is there a function that I can use to do this?

Yariv,
You should really start a new thread with a new question like this, so that more people see it. Some people look primarily at threads that have no responses yet. Also, don't post the exact same question in multiple places. Or, if you must cross-post to some other forum, make sure to mention it in your question text.
I'm happy to be a brick in your Western Wall, but I'm not sure what the main objective is here. Is the main problem really getting access to the "X bytes received in Y seconds at Z bytes/sec" string? Or is it accomplishing the file transfer? And what OS and LabVIEW version are you running?
I think your problem is that you the LabVIEW System Exec command does not allow for the degree of interactivity that you need if you want to issue a sequence of commands to a command-line executable. However, under Windows XP (and, presumably, other Windows versions, though I can't check), you can tell the FTP executable to use commands from a textfile script by using the -s switch, and you can override the prompts during multiple file transfers with the -i switch:
ftp -i -s:FILEPATH SERVERNAME
If you issue a command in this format to System Exec, and make sure to create a file at FILEPATH with your command sequence (one per line), then you should at least accomplish the FTP actions. This won't give you the transfer details in the standard output, unfortunately. However, if you just want a general sense of how much was transferred and how quickly it happened, you can code that in LabVIEW by getting the resulting file sizes and using Tick Count before and after the System Exec call to see how long the transfer took.
Hope that helps,
John

How to retrieve characters like '£' from the database and write to xml file

Hi ,
I have a requirement to retrieve the data from database and write to files in XML format.
I am able to do so successfuly by using XMLElement tag and writing to file through UTL_File package.
All characters like <&@^ get converted properly, but when it comes to multibyte chars like '£', they are not able to get converted as it is.
Can somebody please advise me how to go ahead.
Regards

Thanks odie.
The nls_charset for my database is WE8ISO8859P1 and database version is Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi.
The data (with pound sign) is sitting in one of the columns of the table and when i query it directly, I am able to view it properly.
However when I use the below code to retrieve in XML format and print it to file, it gets changed. This file is also passed to one of the application GUI where this XML gets processsed and it is not visible properly.
below id the sample abstract of code I am using.
Declare
l_file UTL_FILE.FILE_TYPE;
l_clob CLOB;
l_buffer VARCHAR2(32767);
l_amount BINARY_INTEGER := 32767;
l_pos INTEGER := 1;
Begin
SELECT XMLElement("case",
XMLElement("comments",
XMLElement("comment",
XMLElement("comments",a.COMMENTS)
).getClobVal() val1 into l_clob
FROM TO_COMMENTS a
l_file :=
UTL_FILE.fopen (XMLDIR,
test.xml,
'w',
32767);
LOOP
DBMS_LOB.read (l_clob,
l_amount,
l_pos,
l_buffer);
UTL_FILE.put_line (l_file, l_buffer);
l_pos := l_pos + l_amount;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.NEW_LINE('Reached end of file');
END;
The comments column given contains the character like pound.
And once the file is generated and i see using the vi editor, the char is not viewable properly like Â£
And when the same is passed to GUI application to be processed, its not viewable propely in GUI from IE as well like �.

Read blob 's data and write them to a table

I've managed at last to upload a blob to a table database (thanks to KUBA's)
Now I want to retrieve the blob from the database table , read it's contents and insert them to a new table. I want to do this after the upload process finishes...
the blob is always a txt file similar to this
GR;Greece
CY;Cyprus
Because I am a bit lost any guidelines would be very helpfull
thanks

Hi user571628. A couple of days ago I was working on the same thing, I couldn't finish the app. 'cause I was assigned to do other web app., I used the same example as you to upload the image to the DB and someone called "gnewtonaus" came up with what appears to be an excellent idea to do it, you have to use something called PL/SQL web toolkit (I have never used it and don't know how it works)... but this is what you have to do:
You've already solved the upload part so to download the BLOB (say an image in his example) you can use a simple PL/SQL stored procedure like the one below
E.g to display an image (from the DB) on an HTML page you just use

-- Display a photo from the database
procedure display_photo(i_person_id in varchar2) is
v_blob blob;
begin
-- retrieve blob from database
select image into v_blob from pho_photos where person_id = i_person_id;
-- set http headers
owa_util.mime_header('image/jpeg', FALSE);
htp.p('Content-Length: ' || dbms_lob.getlength(v_blob));
owa_util.http_header_close;
-- initiate direct BLOB download
wpg_docload.download_file(v_blob);
exception
when others then
htp.p(to_char(sqlcode)||' - '||sqlerrm) ;
end; -- display_photo

If you get it running please post how you did it, bacause I'll have to come back and do it myself.

Using UTL_FILE i'm able to read csv file. I'm stuck up in appending some more columns to same csvYou'll struggle to append data to an existing CSV.
You'd be better to read the data from one CSV, and create another CSV using that data, and the extra data you want, and then when finished, delete the original file and rename the new file to the old filename.
You should be able to do that using External Tables to read the source file (easier than using UTL_FILE) and UTL_FILE to write the new file.
