Reading and saving real time data

Hi,
I would like to read and save real time data using DAQ card 6004 with my PDA device. There is no problem with reading real time data, I can see it on the PDA's screen successfully. But, when I'm trying to save this real time data, I have the following problem:
-It continuosly asks for file name.
-It only saves the data instaneously,i.e. it only saves the data at the moment.
I'm stuck with this problem, could you please help me? I attached my vi doc.
By the way, I'm using Labview PDA 8.5 version.

oozdemir,
>> -It continuosly asks for file name.
You are prompting the user for a file name each time through the loop. Do this before you enter the loop and pass that file ref in.
>> -It only saves the data instaneously,i.e. it only saves the data at the moment.
By this, I am going to assume you want to append to the file as you go. Two problems, 1. you are saving an array to the file and additional info about the array structure is being saved. You would essentially be creating a binary file filled with array "records" (for lack of a better term) appended one after another. 2. If you want to append to the file, you will need to use the "Set File Position.vi" to locate the file pointer to the end of the file.
This task looks like it runs once per second until the stop button is pressed. You could build an array of all acquired data in the loop and then write it when the loop exits. Just a thought. This app could create a lot of data though.

You need to pass your filename String as a parameter to your functionality. It depends how you're currently set up though. We can't really see the top of your call so it's difficult to determine what you are calling and we don't really know from where you're calling either.
If you're running standalone, then on launch of the application, you can feed in a file name as an argument that you can read in in String args[] in the main function and pass down to your XML splitter.
If you're a method in a class that's part of a bigger pile, you can feed the file name as a String to the method from wherever you call from if it makes sense architecturally.
You might also want to pass down a File object if that makes sense in your current code (i.e. if you're using your file for other purposes prior to the split, to avoid recreating closing/opening for no reason).
Depends what you're trying to do. If I put together a piece like this, I would probably create an <yourcurrentrootpackage>.xml.splitter package.
Also, on a side note, you're problem isn't really reading and writing XML in java, but seems more to be making your functionality generic so that any XML file can be split with your code.

Reading and wrting with selectors

Heres the code is used for Reading. The problem is that when the client send the server some bytes it goes into the loop and exits which is good however it does not delete the Selected Keys set from the selector. I thought that after ever slection process it deletes the set of selectedkeys however I cant seem to get that to work. =/ This is causing the server to keep going through the loop every time the method is invoked =/
     private void ReadMessages() throws IOException {
          int ReadyUsers = Select.selectNow();
          if (ReadyUsers <= 0) {
               return;
          } else {
               Set<SelectionKey> Keys = Select.selectedKeys();
               Iterator<SelectionKey> i = Keys.iterator();
               while (i.hasNext()) {
                    SelectionKey Temp = (SelectionKey) i.next();
                    i.remove();
                    SocketChannel SChan = (SocketChannel) Temp.channel();
                    System.out.println("Finished Reading and writing");

Heres the code is used for Reading.There is no code here that does a read.
The problem is that when the client send the server some bytes it goes into the loop and exits which is good however it does not delete the Selected Keys set from the selector.Your it.remove() does that. The real trouble here is that you are never doing any reads, so the same keys are selected next time around, because they are still ready.
System.out.println("Finished Reading and writing");This printout is lying to you! You haven't finished anything at this point.

Working CSV formatted data in Numbers

I am trying to read a CSV file in Numbers 09. Is there a quick way to reformat the file to Numbers format?

What is the problem ?
As it was explained hjerte many times,
if your system uses the period as decimal separator, the file name must end with ".csv" and the values must be separated by commas
if your system uses the comma as decimal separator, the file name must end with ".csv" and the values must be separated by semi-colons
There is an annoying problem: from time to time, users receive files whose name ends with ".xls" which are in fact csv ones,
others receive files whose name ends with ".csv" which are in fact html tables or other formats.
When you get a wrong behavior, drag and drop the document's icon on the application TextEdit.
Doing that, you will quickly know which is the structure of your document.
If it's really a csv one with the 'wrong' separator, the best scheme is to change temporarily your system setting so that it matches the separators used.
If it use commas, set the system to country/region : USA
If it use semi-colons, set the system to country/region :France.
Numbers will run according to this setting so it will open the doc correctly.
Save as is.
Reset the system to your standard setting and open the new file in Numbers.
This time it will be OK. Maybe you will have some problems with numbers using thousand separators or with dates.
In other cases,you may send the file(s) to my mailbox.
I will look at its internal structure. With a bit of luck, I have a script ready to decipher it.
In other cases, I will do my best to write a new script.
If you must send a file, click my blue name to get my address.

How to backup and restore alien formatted data from/to a CF card - just binary data, not mountable

I'm trying to make a safety backup of data from a Compact Flash card and be able to restore this data to the CF card again in the event of disaster.
The data on the CF is in a non-standard filesystem format - I just want to make a 'bit-for-bit' copy of the data on the CF to a backup of some sort held on the Mac and be able to put it back on the CF again if need be.
I connect the CF card to the Mac using a USB type external adapter box.
I have tried using Disk Utility. I made a ".dmg" Disk Image from the CF apparently OK, but it will not restore the image back to the CF. I get message "Restore failure. Could not validate source - device not configured". I've not managed to find any
After much fruitless digging it's in danger of turning into a second career trying to sort out how to do this - so a cry for help...

Thanks jsd2 - that did help with one part of the puzzle - how to find what the 'dev' was to use in the 'dd' command! When I listed the /dev dir I couldn't see clearly what was what, and could feel a load more googling coming on, but this tool made it clear the CF I wanted was identified as '...disk2'.
I'm trying "dd-ing" a .bin file I extracted from the .dmg backup onto the CF using the dd-GUI tool - but it is very slow, currently indicating another 4 hours to finish the write! I'm not sure the best way to abort.
I wonder if it could be made to go faster if I used the actual dd command from the console, with the right parameters.
Unfortunately I'm also not convinced that the ".bin" format will be any good - it was a choice between that and ".img" so I tossed a coin, for the sake of trying something.
I think it is more likely to work if I used the 'dd' command (via the tool or from the command line) in both directions, ie. to make the copy and then to copy it back - that way presumably the raw byte format should be consistently packaged in each direction at least - but if it takes >4 hours each way with this 32GB CF card then it's not bearable!

My SuperDrive reads and writes these formats. Is this right?

OK, another SuperDrive thread, I'm sorry! After some experimentation last night, I came up with this list of what my drive does.
Read Verbatim 4x DVD-RW movie - All OK (didn't see it first time though)
Erase Verbatim 4x DVD-RW - Toast & DU says Incompatible Format! Erased it in my external instead.
Write Verbatim 4x DVD-RW - Drive spits it out. So no erase or write, just read.
Read Imation 4x DVD+RW - Doesn't recognise there's a disk in there
Erase Imation 4x DVD+RW - No (see above)
Write Imation 4x DVD+RW - No (see above)
Write Imation 8x DVD-R - OK
Write Verbatim 16x DVD+R - Failed in Toast
So I can read DVD-RW, DVD-R, and write to DVD-R. That's it!
Mr drive is this according to System Profiler:
PIONEER DVD-RW DVR-106D:
Firmware Revision: A612
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2000 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: No
So it doesn't do what it should do. Any clues? Can I upgrade the firmware? Or when I sell the iMac do I just include a list of what the drive is capable of?
iMac G4 Mac OS X (10.4.6) 1.25ghz, 17" USB2

David, rather than expieriment your Provile from your Pioneer tells it all except a couple of very important things.
The Media quality, in other words
The problem is multi-dimensional.
First check in your particular profiler on EXACTLY what type(FORMAT) of DISK's your burner will burn.
Next please do not just randomly go out and buy a spool of 30 50 or 100 disc's because they are on sale.
There is a HUGE difference in the type format disc's you buy
There is also a HUGE difference in the BRAND you choose, some are junk.
There is also a HUGE Difference in the SPEED of the media you choose.
If any one or a combination of any of the 3 mentioned above can cause burn error's or no burn at all or spit the disk out.
So it is a good idea to do a little homework on your Optical Drive and see just exactly what it is capable of and what it will use for media.
(ONE LAST NOTE)
Many of the Media Manufactures are becomming aware that many of the Apple Burners are having trouble with there Media. Maxell has just come out with a brand new one that is. Maxell 16X DVD-R.
The key is read the packaging. this new media tells you that it will burn at any speed from 1X through 16X, and it works very well on the older Optical Drives. I also opt to use the individual that include the cases there seems to be much better quality, not like that of the spools.
Remember Apples Drives to date are much pickier than those used in the PC community.
Cheers Don

Reading and processing high freq data in different processes

I am trying to create a program to receive raw data from UDP - EGD protocol, process the raw data then write data to file. The max transfer rate is 100 Hz and when running at this frequency the program cannot seem to process the data quicly enough to maintain a constant timestep ie the interval between data samples is not constant. Any suggestions how I can overcome this problem? I can post the VI if it will help...
Thanks

This is an example of how you can use a queue to move data from one loop to another. I created it from the producer/consumer template in labview. While this solution may work for you right now, I would suggest reading more on the forums about good architecture.

I have to develop a Webdynpro application that will do the following:
Read the Configuration data from an xml file
If stored in a file , and the file is not found, prompt the user to provide the file location.
Pre-Populate the screen(table) with the configuration data
Allow the user to edit the data
Store the configuration data when the user hits the Save button
The config xml file details are as follows:
Regardless of the location of the configuration data, the following fields will be stored
Application (string) will always contain u201CSFA_EDOCSu201D
Key (string) eg LDAP_USER, DB_PREFIX, etc.
Type (character) u201CPu201D = Plain Text, u201CEu201D = Encrypted

How can I export to Text and/or CSV format and get correct page info?

I am using CRVS2010 to upgrade an application from CRXI RDC to .Net. When at runtime I generate the report and export to Text or CharacterSeparatedValues my page footers show Page -1 of 1. Using the CRXI RDC, I see the correct page info in the footers.
When I export to Text, I get the Page -1 of 1 for every page. If I set LinesPerPage to zero, then I get it all on one page, which still has Page -1 of 1 at the end.
If I export to CSV, I get Page -1 of 1 for every line. If I use the viewer to review the report at runtime, and export from there, I cannot export as Text so I have no comparison. However, the Export to CSV from the Viewer as Page -1 of 1for every entry just as my export does.
What do I need to do to get the correct line info? What is that is different from CRXI RDC and CRVS2010 .net that would impact this behavior?

Yes, I am using SP2 for VS 2010 and I'm using the Page N of M formula in the page footer. While my export code was not quite as simple as yours, I did it both ways in my test program with the same results. A one page report whose footer says Page -1 of 1.
Here's the relative code snippet:
#if 0
    CrystalDecisions::Shared::ExportOptions ^exportOptions = gcnew CrystalDecisions::Shared::ExportOptions();
    exportOptions->ExportDestinationType = CrystalDecisions::Shared::ExportDestinationType::DiskFile;
    exportOptions->ExportFormatType = CrystalDecisions::Shared::ExportFormatType::Text;
    TextFormatOptions ^textFormatOptions = exportOptions->CreateTextFormatOptions();
    textFormatOptions->LinesPerPage = 0;
    textFormatOptions->CharactersPerInch = 11;
    exportOptions->FormatOptions = textFormatOptions;
     CrystalDecisions::Shared::DiskFileDestinationOptions ^diskFileDestinationOptions = exportOptions->CreateDiskFileDestinationOptions();
     diskFileDestinationOptions->DiskFileName = gcnew System::String("c:\temp\test.txt");
     exportOptions->DestinationOptions = diskFileDestinationOptions;
    thisReport.Export(exportOptions);
#else
    thisReport.ExportToDisk(CrystalDecisions::Shared::ExportFormatType::Text, gcnew System::String("c:\temp\test.txt"));
#endif

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

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

can somone please help me to resolve this problem?

Sameera

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

Process using Webservice in Reader and Writer becomes slow while connecting processors

Hi,
I have a process that reads from a web service and writes to a web service. When I try to modify the code(after stopping the running process) by adding new processors or change the current connections, the connecting arrows take forever to connect and sometimes the director hangs for a long time. There is no issue in other processes where I read and write from staged data.
How to overcome this isue?
Appreciate the help!
Regards,
Ravi

Hi Nick,
Thanks for the advice. In the scenario where upgrade is not an option, is there any workaround to this issue?
What I've found is if I strip the next processor of all its connections, then it gets connected to the previous processor pretty quick.
EDQ hangs if the processor has other input/output connections and I try to connect it to another processor)
P1>---<P2> <P3 ---------- P2 to P3 connects fast as P3 is standalone
P1>---<P2> <P3>---<P4> ---------- In this case, when I try to connect P2 to P3, it hangs forever.
I've a complex process and just for adding a few processors in between, I will not be able to connect the rest of the processors all over.
Regards,
Ravi
