Incorrect Reading from Read Velocity.flx in LV 2011

Matt,
How cold is it where the FieldPoint unit is located? It is roughly -30C...It is located in an enclosure and other than the TC problem everything is running fine. I could try changing the temp in the reefer to a warmer temp and see if performance is affected.
Have you tried unplugging and re-plugging each of the TC-120 and CB-3 several times since the unit was placed in the cold environment?No do you think that would help...I will try that this afternoon.
Are the CJ and sensors reading properly with MAX, or with the short, test sensors? I am unsure if the CJC is reading proerply. I do not know the actual temperature in the compartment but from what I can tell it is in the ballpark of the refridgerator's set temperature. I have not tried connecting another TC I planned on doing that this afternoon (this is my second job). My thermocouples are attached to shielded & twisted thermocouple wire (from Omega). The wire runs any where from 10' to 40' to the FP module. In th e"control" room where it is -30C they terminate to the FP module. Last night I warmed up the wire in the control room and notice that my temperature readings had changed. Do you think the wire itself could be the problem? Now I plan on attaching a TC to one of the open channels and checking the readings. Then I was going to check the the temp of the TCs in each room (comparing the measurement with an independent temperature device). I really hope it is not the wire b/c that woudl be a real pain trying to run it again!
Thanks for all of your input Matt!

Can hitting the Brand name of an eraeder stop a generic reader from reading the ebook?

I am running windows xp on my PC & when I downloaded Adobe Digital Editions I might have accidentally marked a brand name reader instead of a generic. When downloading a book from the library I can read it on the PC but when I tried loading it on to the eReader all I get is the contents pages & then a "File Error" message & that is it.
I normally do this from my lap top & have had no problems.
If having authorized the PC with the wrong brand name instead of generic is the problem how do I reset Adobe Digital to have just the generic settings.
I tried to uninstall the Adobe & then re install but it just kept the original authorization settings & gave no option to change.
I am not very computer literate so if you can help in plain language it would be greatly helpful.
Thank you to all who answer.

How can I stop Adobe Reader from reading (seeking) the floppy drive when opening/closing any PDF?

Ever since I opened a PDF file from my floppy drive Adobe Reader insists on checking/seeking/reading the floppy drive whenever I open and whenever I close any PDF (not using the floppy). It is very annoying, as I use many PDFs per day and it creates a delay and noise every time.

VISA Read gets incorrect data from serial connection

I am having difficulty using the VISA functions in LabVIEW to read data from a virtual COM port. Data is being sent from a serial to USB chip via a USB connection using OpenSDA drivers. I have a python program written to read from this chip as well, and it never has an issue. However, when trying to achieve the same read in LabVIEW I am running into the problem of getting incorrect data in the read buffer using the VISA Read function.
I have a VISA Configure Serial Port function set up with a control to select the COM port that the device is plugged into. Baud rate is default at 9600. Termination char of my data is a newline, which is also default. Enable termination char is set to true. A VISA Open function follows this configuration, and then feeds the VISA Resource Name Out into a while loop where a VISA Read function displays the data in read buffer. Byte count for the VISA Read is set to 20 so I can read more of the erroneous datat, however actual data will only be 6-12 bytes. The while loop has a wait function, and no matter how much I slow down the readings I still get incorrect data (I have tried 20ms thru 1000ms).
The data I expect to receive in the read buffer from VISA Read is in the form of "0-255,0-255,0-255\n", like the following:
51,93,31\n
or
51,193,128\n
And occasionally I receive this data correctly, however I intermittently (sometimes every couple reads, sometimes a couple times in a row) get incorrect readings like this:
51,1\n
51,193739\n
\n
51,1933,191\n
51,,193,196\n
51,1933,252
51,203,116203,186\n
Where it seems like the read data is truncated, missing characters, or has additional characters. Looking at these values, however, it seems like the read was done incorrectly because the bytes seem partially correct (51 is the first number even in incorrect reads).
I have search but haven't found a similar issue and I am not sure what to try from here on. Any help is appreciated. Thanks!

The first thing is that none of the error clusters are connected so you could be getting errors that you are not seeing. Are you sure about the comm parameters? Finally, I have never had a lot of luck looking for termination characters. You might want to just capture data and append each read into one long string just to see if you are still seeing this strangeness.
What sort of device is returning the data? How often does it spit out the data? How much distance is there between it and your computer? Can you configure it append something like a checksum or crc to the data?

Crystal Report that reads from an XML file Datetime or Date

I have a Crystal Report 2008 that reads from an XML file, the source File XML Date data looks like this: 2008-03-10
But the Crystal Report interpreted by datatime, I need the Crystal Report to look like this: 2008/03/10 (date) not 2008-03-10T00:00:00-05:00 (datatime)
Look at an example (source file xml, report, and parameter file to execute report) at url: http://www.5websoft.com/sample.zip
Import the file in the design and will to verify that interpret incorrectly the fields of type date as datetime
not mapped currently for fields..
Help.....
Thanks!

You could always reformat the field to only display the date portion:
Format Field > Date and Time tab; choose the date style you need here.
Or create a formula to extract just the date and use this field in your report:
date({table.field})

I assume you know where your catalogue file (the lrcat file) is located. In the same folder is a previews lrdata folder which you should delete or rename in Explorer, then start LR again.

Reading from a file. How to ask the user for file name at run time????

I have the code to read from a file but my problem is how to prompt the user for the file name at run time.
import java.io.File;
import java.io.FileNotFoundException;
import java.util.InputMismatchException;
import java.util.Scanner;
public class FileRead {
    public static void main(String args[]) {
        Scanner scan = null;
        File file = new File("Results.txt");
        String number;
        try {
            scan = new Scanner(file);
            while (scan.hasNext()){
            number = scan.next();
            System.out.println(number);}
        catch (FileNotFoundException ex1){
            System.out.println("No such file");
        catch (IllegalStateException ex2){

            System.out.println("File structure incorrect");
        finally{
            scan.close();}
}Any hints would be greatly appreciated. Thank you in advance

I have read through some of the tutorials that you have directed me too and they are very useful, thank you. however there are still a few things that i am not clear about. I am using net beans 5.0 I have placed a text file named Results.txt into the project at the root so the program can view it.
When I use the code that you provided me with, does it matter where the file is, or will it look through everywhere on the hard drive to find a match?
This code compiles but at run time it comes up with this error
run-single:
java.lang.NoClassDefFoundError: NamedFile

    fileName = user.nextLine().trim();
    File file = new File( fileName );     // create a File object

    Scanner scan = new Scanner( file );

      num = scan.nextInt();
      square = num * num ;
      System.out.println("The square of " + num + " is " + square);
}his is the code that i used. It is the same as the code you posted for me (on chapter 23 I/O using Scanner and PrintStream) Sorry im just really stuck on this!!

Hello Janet,
I would recommend this article named 'Disk cannot be read from or written to' when syncing iPod or 'Firmware update failure' error when updating or restoring iPod found here http://support.apple.com/kb/ht1207
Outdated operating system software
Make sure you have the latest updates for your operating system, which may include improvements for device connections. For example, many USB and FireWire improvements have been included in Windows Service Packs.Check for Mac OS X downloads. Check for Windows updates.
Computer needs updates
Make sure you have the latest updates available for your specific computer model (or components for home-built PCs). These are usually available for download on the support website for the maker of the PC (or component). Many USB updates are listed as "Intel chipset" or just "chipset" updates on PC manufacturer's support and download websites.

Some software can interfere with iTunes, making it unable to write files to your iPod. Think about what software you have installed, and try disabling any add-ons that might be interfering with iTunes. Check your suspected software's documentation or contact the software maker if you need assistance with disabling the application. Out-of-date or incorrectly configured security software frequently causes this issue. See these steps for identifying and troubleshooting third-party security software.
Damaged files
If one of your music files or photos is damaged, iTunes may display one of these errors when transferring that file to the iPod.

Conflict with third-party hardware
Third-party USB or FireWire devices may also interfere with iTunes' ability to communicate with your iPod. Remove all USB and FireWire devices except the keyboard and mouse before reconnecting your iPod to the computer.
Bad hardware
Hardware failure or non-compliant hardware can cause these errors. This could be an issue with iPod hardware or with the cable or dock you're using, but more often it's an issue with the USB or FireWire card or interface in your computer. Some USB and FireWire interfaces just don't work very well. If you isolate the issue to the USB or FireWire interface in your computer, you may want to try a different port, get the computer serviced, or replace the card or interface with a better one.
If you isolate the issue to an Apple-supplied cable or dock, or the iPod itself, you can get it serviced here.

FI/CO - Reading from COSP to COEP but cannot get PO and Matnr

Hi guys, first question on this forum so forgive me if i post incorrectly.
I have created a report that reads budgeted,planned,commitment and actual values for CO/FI (PS).
This reads from prps to cosp and onto coep where the latter i need to retrieve the purchase order number, the materials and finally the profit segment number for where i select from ce40max_acct to determine product hierarchy etc.
The problem i am having is that when reading coep from cosp (and using an outer join as not all planned etc records will have an actual record) i cannot distinguish between different Purchase orders (where they have the same material,cost centre,controlling area). This is resulting in my figures getting messed up.
Hope this is somewhat clear but i will attach the code that i am using so that someone here may see what i am doing wrong.

Hi,
I have already developed the report which gives the project / WBS data like:
- Planned values
- Budget
- Commitments
- Actaual cost ( billed / Unbilled )
These are the table i get these info from.
1. Planned values - COSP with OBJNR / VERSN / GJAHR and COSP-VRGNG = 'RKP1'
2. Budget         - BPEG with OBJNR = wbs obj no / WRTTP = '41' / VORGA = 'KBUD'
3. Commitment     - COOI with LEDNR = '00' and OBJNR = wbs object no.
4. Actual cost    - COVP ( this is join of COEP and COBK) with LEDNR = '00' and OBJNR = wbs object number
Let me know if you need any information.

How to read from a certain location is a file?

hi! i am new to programing and i have a problems abt reading from a file. i have write the following to a file using FmtFile :
10 (a numbers)
name,phone,product (some strings)
9 (a numbers)
when i user ScanFile to read the second number(9 in the above example), i got a wrong value. the command i use is:
ScanFile (filehandle, "%d", &number1);
ScanFile (filehandle, "%s[t44]%s[t44]%s",name, phone product);
ScanFile (filehandle, "%d", &number2);
number1 and number 2 are integers and name, phone and product are char arrays.
can anyone tell me where have i gone wrong? or maybe someone can tell me how can i read the 2nd number without reading the 1st number
and the strings.

Let's look at your file: if I correctly interpret your question, one row in it should like like this:
10,name,phone,product,9
In this case you could use the following formatting string to read all data from the string:
"%d[x]%s[xt44]%s[xt44]%s[xt44]%d"
[x] means to discard terminator, in order to read from strings, for example, "name" and not "name,". It's important in this case to put ALL field separators.
Maybe your problem is that in the file you don't have separators between strings and numbers: in this case the last "%s" should read the '9' inside the last string and the subsequent "%d" matches with incorrect area in the file (end-of-line or next row).
Hope this help

SQLDeveloper tool script execution aborts with Error report: No more data to read from socket

Hello,
Strange behaviour of the SQLdeveloper tool while executing script with typical DDLs like:
Create Table,
Alter Table
Create Trigger ( use of :new and : old attributes in tehe body of trigger ).
Insert Into....
Scripts works ok from time to time.
But sometimes coincidentally aborts with the error :
Error report:

Do not understand where is the problem.
Scripts works ok when executed in SQL*Plus on server ( where Oracle RDBMS resides ).
The version of SQLDeveloper is

Big probelm dealing with arrays to read from instrument

Hi All,
I have been struggling with this issue for weeks now and hope someone from this forum can help me out. I am trying to read data from a phmeter via the rs232 of my computer. I am reading using the basic VISA read and write code and have configured my Serial configuration to terminate read at a Line Feed(\n). I am using the code provided in my attachement to parse the data to read only the ph number using the string functions search and replace, etc.
As the phnumber I get displays only for a fraction of a second (when my instrument tranmits data ie every 5 seconds) using just this string function, I have added a case statement to look for strings>0 to display the data (ph number) till the next update. I have shown this in my snippet too. This works fine but I am getting a bunch of 0's on the output array when my case is false.
I have inialized the array with dimension size 0 too and then used the build array function to append all the new data to my existing array using a while loop with shift registers, but the appended array I get has every ph number output with 7 other 0's. I guess the build array function allows 8 element arrays to be formed with every transmision, or maybe the way I am parsing the data is incorrect. I am pretty new to Labview so don't know what I am doing wrong.
Conversely, in order to work around this issue I have tried adding 8 elements of my appended array at a time to see if I can generate one real ph number with every transmission, but don' know how to do this either. I need to get an array of elements with all the different non-zero ph numbers to do a running average and min/max function but have contacted many people who could not help me come up with a suitable solution to this problem.
I am looking forward to all suggestions to make my code work best. I'm sorry I could not attach the entire code as its proprietary information.
Thanks a lot!
Solved!

Thanks for your suggestions Smercurio and Dennis Knight. How do I configure the VISA read to read only when data is available ie being sent by my instrument? I was looking into the Read Status function but I thought that is for GPIB only. Is there any other case statement I can write to do this efficiently?
Please see the cleaned up version of my code in the attachment. I need to average samples (MEAN)collected every minute, as well as check the min and max values received per minute. Currently the mean includes all the 0 elements I am getting in my array which is why I am trying to get rid of them.
Also with the append array function which was suggested to me by an NI engineer, my ph number in the case statement updates after a significant time lag. This is the other issue I am fighting with. Initially I was not using the appended array as I did not have a need to do the averaging and my code was updating pretty fast.
In the event that the array being put out has the seven 0's by nature, is there a way to add up 8 elements of the appeneded array at a time (since most are 0's) and build another array again. I know this is unnecessary processing if I can just configure the read to read with every data transmission.
Thanks again.. and I look forward to speaking to you and others on this issue.

Trouble reading from serial instrument and DAq simultaneously.

Greetings,
I am having some trouble getting my VI to read from my DAq and a serial instrument at the same time. If I run the subVI's simultaneously (i.e. subANG is running in one window and subVEL is running in a second window) both return the proper values and behave as I would expect. However, if I call the subVI's into a parent VI and try to run them both in the same loop structure subANG gets stuck and will not resond with a change in signal.
I have also tried to use a stacked or flat sequence to separate out the execution of subVEL and subANG, but I still get the no response from subANG.
The most confusing thing is that if I run Parent.VI in one window and then create a copy of subANG (call it '....-copy' or whatever) and run it in a second window, Parent.VI behaves properly and will refresh the readings as they appear in '...-copy'.
I have attached 3 files.
(1) subANG.VI     -This reads an RS232 signal from an inclinometer. The signal is refreshed every 10ms or so.
(2) subVEL.VI      -This reads raw voltage from one channel on the DAq, calculates the mean then converts that into a pressure differential and finally a velocity based on the pressure and temperature inputs.
(3) ParentVI.VI     -This simply calls and displays the subVI's
My guess is that it is a buffer issue, but I am stumped. Does anybody out there in Labview land know why this might be happening? All suggestions welcom.
Solved!

I am noticing it is not an NI DAQ card. How are you communicating with the DAQ? If it is using a serial port, that could be your problem.
I also highly recommend using the VISA drivers for serial communications instead of the serial.llb VIs.
