How to read from a HPIB instrument using GPIB software?

How Can I read from a HPIB instrument using GPIB software and library functions in Visual Basic Environment? In HPIB we do not have to send query first but in GPIB we do? Although writing and sending a command is to a HPIB instrument is pretty much the same as a GPIB instrument. Any help or suggestion?
Thanks in Advance

HI,
HPIB and GPIB are the same thing at a low level in terms of instrument communication. They are both compliant with the IEEE 488.2 standard.
The difference is the driver you have to use. Each manuafacturer has to develop a driver to control the interface ont he host. For National Instruments interfaces you use NI-488.2 (which you refer to GPIB functions). For HP interfaces you need to use the SICL library. For information using this library in Visual Basic you'll have to look at the SICL documentation.
You can also use VISA (HP-VISA) which would allow you use NI interfaces or other buses in the future.
Hope this helps.

How to read from text file?

I would like to read data (frequencies) already written in a text file. I will need read these frequencies one at a time to set the function generator (as part of my data acquisition application), acquire data that is in turn written to a file and then go back and read the next frequency from the file to repeat the process again. I also have another idea of doing the same, which is read all the frequencies from the text file and populate a table and a frequency value is picked from the table each time to go through the process mentioned above.
Can anyone suggest the following: (1) How to read from a text file, (2) What could be the most efficient way of solving my above problem.
I am a new LabVIEW user and any help will be appreciated.

Hi Research,
Depending on the format of the data file, there are a few options for reading it. If it is tab delimited, you may want to use the Read from SpreadSheet File VI which will read the file into an Array. You can then use the Index Array VI to pull out individual entries. If the files is ASCII but not tab delimited, you could use the regular Open File and Read File VIs. You can either read the file out piece by piece, or read the entire file into a string and then use the Match Pattern VI to parse out the different elements (there are actually many ways to do this - check out the Strings subpalette).

DPM encountered an error while reading from the recovery point used for recovery.

Hi Guys I'm getting this error:
DPM encountered an error while reading from the recovery point used for recovery. Either the recovery point no longer exists or, if you
selected a share for recovery, the path to its contents is missing from the recovery point. (265)
The DPM Server is on Windows 2012 DPM is 2012R2 4.2.1273.0
The Server being backed up is 2012 R2 with DPM Agent 4.2.1273.0
The Server has 3 Data Volumes (C: Drive) and D and E its the D and E drive that i get this error if i try and recover data from DPM. the C Drive is fine. the D and E Drive are different
in that 1 De-dupe is enabled and 2 the Shadow Copies for these Volumes are stored on separate Disks F and G respectively.
I've removed the Protection from drives D and E and reinstated it but every recovery point created
brings up the same error message. I'm not sure where to go next do I need to Protect the Disks that have the Shadow copies on also? Many thanks in advance Gordon.

Hi,
It seems you are in a configuration where the Windows 2012 based DPM server does not understand how to read Windows 2012 R2 Dedup data structure which is what the DPM replica volume is.
See the DPM supported and unsupported scenarios
here under the deduplication issues section.
We have a fix in DPM2012 R2 UR5 that will protect the Windows 2012 R2 dedup volume in a non-dedup state on the DPM Server, but unfortunately that will not allow previous recovery points to be read.
KB3021791-Description of Update Rollup 5 for System Center 2012 R2 Data Protection Manager
Backup job for dedupe-enabled volume on Windows 2012 R2 fails. For example, Data Protection Manager backup might fail for following setup:
Data Protection Manager2012 R2 is installed on Windows Server 2012.
Data Protection Manager is protecting a dedupe-enabled volume on Windows Server 2012 R2.
This also applied to restores as the above was for D2D2T backup that may fail as it needs to read the recovery point to back it up to tape.

How to read from properties file

I think i have mixed it up :)
I have looked at it again and believe you are using regular JSP portlets.
Can you tell what you want to achieve by reading .properties file. Are you meaning the preferences of the portlet or what exactly are you trying to do?
Reading propertie files is easy:
// Read properties file.
Properties properties = new Properties();
try {
properties.load(new FileInputStream("filename.properties"));
String myKey = properties.getProperty("yourKey");
} catch (IOException e) {

How to read from 4 serial ports

Hi
Does anyone know how to read from 4 COM ports with only 2 interupts? I can
manage it by using Close serial driver.vi, however this makes the amount of
allocated memory by Labview increase throughout my experiment and thereby
slows down the computer. I use Labview 4.0.1 on Win95.

No, the iPad doesn't work that way. The only thing you can access is camera cards (with the adaptor).

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");
