LabVIEW and write protected DLL files
Hi,
We are building Labview dll's within a source controled environment (ClearCase). These dll's can only be modified in a particular view, but they should be useable in other views. The problem is that LabVIEW seems to be unable to open and run a write protected dll. I don't want to do any unreserved checkout, i want to use automatically the latest version of these DLL's, but they are always write protected.
Does anyone runs in the same poblem and solved it?
Regards,
Sunny
Hello,
I know that the last message was post a long time ago, but I would be interested by a reply also, because I necountered exactly the same problem with Labwindows CVI 8.0 and clearcase 6.0. I mean :
My executable calls some DLL.
the DLL are managed by clearcase and not checkedout.
I have an error launching the executable.
If I just copy/paste the source folder from clearcase to a temp directory, then CVI executes normaly the project. It is the same behavior if I checkout all dll called by the executable.
I thought that calling a dll requires only read access!!!
Is anybody can help me?
Regards,
PFD

How to view waveforms in DIAdem that were saved in Labview using "write waveforms to file" VI
I'm new to DIAdem but would appreciate any help to my question.
I seem to be having a little trouble but how do I view waveforms
in DIAdem that were saved in Labview using "write waveforms to file" VI??
tks, TerryHello,
There are several ways to write waveform data from LabVIEW so it can be accessed from DIAdem. Two of the easiest ways are to use either .lvm files or .tdm files. You can write .lvm files using the Write LabVIEW Measurement File.vi which is located in the File I/O palette. You can write .tdm files by using the storage VIs which are located in the File I/O >> Storage palette. So, I would recommend using either of these file formats if you are developing a new application since these can be loaded into DIAdem directly.
If you are interested in loading files that where already created from the Write Waveforms to File.vi, I am wondering what file type you are using. For example are you saving your files as .dat or .txt with your Write Waveforms to File.vi? Feel free to reply to this thread with this information and I would be glad to help you out.

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/,?????????

2,07,Balance Free,161
can somone please help me to resolve this problem?
Regards !
SameeraAre 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 -

Thanks for your reply in advanceIf 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");

Can't un-write protect TDM files
I am using the storage VIs to manipulate a TDM file that was created using the TDM header writer API. When I try to do any operations on it (specifically, deleting a channel), i get error -2561 "Data storage is write-protected.". I have checked the permissions on the file and they should be correct.
I ran some tests and found that i can create a TDM file using the storage VIs and delete a channel without any issues. According to LabVIEW, the file created using this method has the same permissions of the problem file.
Do you think this could be a bug with the TDM header writer VIs? Or am i missing something obvious?
I have attached files showcasing the issue.
Thanks in advance for any help.

TDM test.zip 131 KBBazookazuz-
The standard is described in the Developer Zone described above. TDM files are binary files written such that it follows a particular pattern. That way the data can be easily retrieved and interpreted later. It is written in the fashion to save disk space and to be created/modified quickly. All TDM files acquiring data from multiple channels follow the same format alternating between each channel taking each sample (also described in the Developer Zone article). By converting the data to End-to-End, it makes all the data for each channel together.
In order to distinguish between the modified and unmodified tdm files, there is no way to just look at the file type and know without a naming scheme. Programmatically, you can parse out the first few data sets and see if they are the same channel and then you can determine from there.

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?

Wells Manufacturing CorpYariv,
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,

Bug in LV8 : 'Save for previous version' and 'Write to Binary File' VI
Hello
I am using LabVIEW 8's revamped 'Write to Binary File' VI with a 'TRUE' boolean constant wired to the optional 'prepend array or string size?' to write non-trivial structures to a binary file. I then read the file with the 'Read from Binary File' VI and everything is fine. I don't wire anything to the 'file (use dialog)' input (don't know if this can help).
However, after saving my VI for LabVIEW 7.1, I cannot read the binary files created with the LV7 version of the VI anymore. After examining the LV7 converted version of the VI, there is a 'FALSE' boolean constant that is wired to the equivalent of the 'prepend array or string size' input, which breaks the binary format that is expected.
The attached files are LV8 and 'saved for LV7' versions of a dummy VI that writes an array of 5 integers into a binary file. To test the bug, start LV8, open the LV8 version, run it and create a 'test-lv8.bin' file, then open the LV7 version, run it and create a 'test-lv7.bin' file. Check the content of the two files : the size of the array is indeed missing from the 'test-lv7.bin' file, which can be assimilated as a bug in my opinion.
I think I found another one too : if in LV8 I wire the 'cancelled' boolean output of the 'Open/Create/Replace file' to the selector of a case structure, the 'converted to LV7' version VI will have an error, saying the Case Structure selector is not wired.
Could someone please confirm these are indeed bugs ?
Thanks in advance and have a nice day.

Test Binary File v7-v8 LV7.vi 15 KB
Test Binary File v7-v8 LV8.vi 7 KBI'm using LV8.6 and need to read a .bin file created in MATLAB. This file obviously does not contain the 4 byte header that LabVIEW prepends .bin files with. So when I use Read from Binary File, I get no data (I'm trying to read an array of doubles). I've tried making my .bin file both in native and big-endian format and changing the representation (double, int64, float64) but none of this works. I noted that if I create the same array in a .bin file in LabVIEW and wire a FALSE to the "prepend array or string size?", my VI for reading .bin files can't read this file either.
Any work-arounds here?
(I'll try attaching my write & read VI's)

How can I read, millions of records and write as *.csv file
I have to return some set of columns values(based on current date) from the database (could be million of record also) The dbms_output can accomodate only 20000 records. (I am retrieving thru a procedure using cursor).
I should write these values to a file with extn .csv (comma separated file) I thought of using a utl_file. But I heard there is some restriction on the number of records even in utl_file.
If so, what is the restriction. Is there any other way I can achive it? (BLOB or CLOB ??).
Please help me in solving this problem.
I have to write to .csv file, the values from the cursor I have concatinated with "," and now its returning the value to the screen (using dbms_output, temporarily) I have to redirect the output to .csv
and the .csv should be in some physical directory and I have to upload(ftp) the file from the directory to the website.
Please help me out.Jimmy,
Make sure that utl_file is properly installed, make sure that the utl_file_dir parameter is set in the init.ora file and that the database has been re-started so that it will take effect, make sure that you have sufficient privileges granted directly, not through roles, including privileges to the file and directory that you are trying to write to, add the exception block below to your procedure to narrow down the source of the exception, then test again. If you still get an error, please post a cut and paste of the exact code that you run and any messages that you received.

The response from Apple/iTunes was extremely poor and did not solve the problem.
I have a look in msconfig and observed which applications/services were running - one of which was the 'Apple Application Support'
So ... I had a look at what was in this folder and found the APS Daemon.exe file causing all the trouble.
So ... I simply deleted the Apple folder found in C:\program files\common files\.
I did a restart and did not get the MSCVCR80.dll or Error 7 (windows 126) error messages.
I reinstalled the current version of iTunes (for the 16th time!)
Hey presto!!!
IT WORKED :-O Woooohooo!!!
So ... to all those smarty-pants boffin-brianiacs out there (apple/iTunes): this is how you do it!!!!!!!!!!
YOU DO NOT NEED TO UNINSTALL ALL THE APPLE/QUICKTIME OR RELATED PROGRAMS - JUST DELETE THE APPLE FOLDER IN THE C:\PROGRAM FILES DIRECTORY.

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.
RegardsThanks 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 £
And when the same is passed to GUI application to be processed, its not viewable propely in GUI from IE as well like �.
