DAQ problem reading data

I just instaled the PCI board together with the CA-1000
Connector Accessory Encloser. The test panel works, so I know that the device is installed. But when I connect a signal to the port on the CA-1000, I don't see
the signal appearing on the test panel display. I just
see a signal that is constant,
with a little variation.
By the way, I also have the PCI-GPIB card installed.
Thanks! Matt

Chuck;
The problem there is most likely due to a bad connection somewhere.
My suggestion to you is to cross check the connection you made with the Users Manual of the CA-1000 and DAQ board to confirm you done everything accordinly.
If that is not the case, the CA-1000 is probably damaged.

Problem reading data from oracle database 11g using OleDbDataReader

Hi everyone I work with Visual Studio 2010 and C# programming language. I have a problem reading data from the oracle database. I created a WPF application with my main Window Xaml and class files and 1 more class called DataFiles. The thing I want is to read some data from the database on my grid in my WPF window. Problem is even though it connects to the database the grid is always empty. It isn't the connection string as I tested it and it connects to the database the problem seems to be in showing the LASTNAME (PREZIME in my native tongue) on the grid which is what it's supposed to do.
Here is the code:
Data Files Code
using System;
using System.Collections.ObjectModel;
using System.Data.SqlClient;
using System.Data.OleDb;
namespace SQLKonekcija
 public class clsEmployee
 public string Prezime { get; set; }
 public class DataAccess
 OleDbConnection oleCon;
 OleDbCommand oleComd;
 public DataAccess()
 string connectionString = "provider=ORAOLEDB.ORACLE; data source=ORCL; password=****; user id=****;";
 oleCon = new OleDbConnection(connectionString);
 public ObservableCollection<clsEmployee> GetAllEmployee()
 ObservableCollection<clsEmployee> EmpCol = new ObservableCollection<clsEmployee>();
 oleComd = new OleDbCommand();
 oleComd.Connection = oleCon;
 oleComd.CommandText = "Select PREZIME from UPOSLENICI";
 oleCon.Open();
 OleDbDataReader Reader = oleComd.ExecuteReader();
 Reader.Read();
 while (Reader.Read())
 EmpCol.Add(new clsEmployee()
 Prezime = Reader["PREZIME"].ToString()
 oleCon.Close();
 return EmpCol;
 }And here is my main window.cs code
public partial class MainWindow : Window
 clsEmployee objEmpToAdd;
 DataAccess objDs;
 public MainWindow()
 InitializeComponent();
 private void Window_Loaded(object sender, RoutedEventArgs e)
 objDs = new DataAccess();
 dgEmp.ItemsSource = objDs.GetAllEmployee();And the XAML
<Window x:Class="SQLKonekcija.MainWindow"
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
 <Grid>
 <DataGrid AutoGenerateColumns="False" Height="237"
 HorizontalAlignment="Left" Margin="18,66,0,0" Name="dgEmp"
 VerticalAlignment="Top" Width="466" ColumnWidth="*"
 >
 <DataGrid.Columns>
 <DataGridTextColumn Binding="{Binding PREZIME}" Header="Prezime"></DataGridTextColumn>
 </DataGrid.Columns>
 </DataGrid>
 <TextBlock Height="42" HorizontalAlignment="Left" Margin="18,15,0,0" Name="textBlock1" Text="TEST CONNECTION" VerticalAlignment="Top" Width="462" TextAlignment="Center" FontSize="28" FontWeight="ExtraBold" />
 </Grid>
</Window>
The guys on the MSDN forums told me I should ask the question here so sorry if it's not your field.
Hope u guys can help, thanks.

I tried it, commented out the reader.read and have the following connection string
string connectionString = "provider=ORAOLEDB.ORACLE; data source=ORCL; password=****; user id=****; OLEDB.NET=True"
Unfortunately the result is the same.

JavaConsole Error: Problem reading data from server

HI All
We are getting this error on java console on a page:
Error: Problem reading data from Server - Java.Security.AccessControlException:access denied (java.util.PropertyPermission http.strictpostredirect Read)
In this page we are not firing a SQL Query of huge data.
Any suggestions on this why it is happening?
Thanks
Manisha

Manisha,
I think JVM(Java Virtual Machine) is trying to access something at network level and it cant able to find it.Or any new patches of java is installed.
Or may be due to IIS or Applet,Don't know exactly.
You can find some answers in below links:

Problem reading data from two tables

Hi experts,
I'm developing a JDBC - IDOC scenario that needs to read data from two oracle tables. I have created a BPM that has a initial fork for the two channels and it works fine.
The problem is that I need to read data from the first, two or both tables depending if there is data to read. If there is data in the two tables it works, but if only there is data in one of the two tables, I have read problems. I have tryed to set the 'neccesary branches' to 1 but this is a problem when I have data in both tables.
Any idea?
Best Regards,
Alfredo Lagunar.

Hi,
have your fork step inside a block and then right-click your block to insert a deadline branch to your BPM process and specify the time after which your BPM process should be cancelled.....so if in that time, you get data from both tables, your BPM will work okay otherwise if that time is over, then your BPM process will be cancelled.

Problem reading data from nested internal table.

Hi,
Below is my code;
*********SAP Code********
TYPES: BEGIN OF v54a0_scdd,
 fknum LIKE vfkk-fknum,
 change LIKE vfkkd-updkz,
 x TYPE v54a0_scd,
 y TYPE v54a0_scd,
 tvtf LIKE tvtf,
 END OF v54a0_scdd.
SCD table for dialog
TYPES: v54a0_scdd_tab TYPE v54a0_scdd OCCURS 1.
*********SAP Code********
*Custom declaration*****
data: wa_freight_costs type v54a0_scdd_tab.
data: it_freight_costs type v54a0_scdd_tab occurs 0.
*****Here data is getting appended to it_freight_costs. P_frieght_costs is coming from standard program.
 move p_freight_costs TO wa_FREIGHT_COSTS.
 append wa_freight_costs to it_freight_costs.
 clear wa_freight_costs.
***Now the problem is here. I am not able to read the data from the nested internal table x-item.
if i use <fs_f_costs> to move data from it_freight_costs in the outer loop, i get a syntax error; "the line type of the table it_freight_costs is not compatible with field symbol type <fs_f_costs>" 
 FIELD-SYMBOLS: <fs_f_costs> type line of v54a0_scdd_tab.
 LOOP AT it_freight_costs assigning <fs_f_costs>.
 LOOP AT <fs_f_costs>-x-item ASSIGNING <fs_freight_item>.
 I want to read <fs_freight_item>-vfkp-netwr.
 ENDLOOP.
Can anyone guide me?

A quick look at how I would do this. Note I haven't checked if this compiles just done a quick brain-dump.
DATA: lr_f_costs TYPE REF TO v54a0_scdd_tab,
 lr_f_cost TYPE REF TO v54a0_scdd.
LOOP AT it_freight_costs REFERENCE INTO lr_f_costs.
 LOOP AT lr_f_costs->* REFERENCE INTO lr_f_cost.
 ENDLOOP.
ENDLOOP.
As you can see I personally prefer pointers to field symbols - I don't believe there is any performance differences and because of my background in other languages pointers make more sense to me.

Problem reading data file (JDK1.3x)

Here's what I'm trying to do:
I want to read in data from a text file, parse it into records and fields and insert it into an oracle database.
Info about the data file:
I have an excel file that contains rows of data. Some cells can contain data (text) that has multiple lines and line breaks. This text data can contain commas, single quotes and double quotes.
Using excel, I save this excel file as either a tab delimited or csv file.
The problem:
I use the following java code to open the file, and reads it's contents:
String fileData = "";
BufferedReader br = new BufferedReader(new FileReader( "filePathAndName" ) );
StringBuffer contents = new StringBuffer();
String line = "";
while( ( line = br.readLine() ) != null )
{ contents.append( line ); }
br.close();
fileData = contents.toString();
//code to parse data goes here
Remember, the file is delimited by tabs or commas. A record (an excel row) is delimited by a carriage return. A single value/field can contain multi-line text.
The problem I'm experiencing is that using the code specified above to read in the data from the file, I lose all tabs, new lines and carriage returns, so my stringTokenizer/regular expression code to parse the data doesn't work correctly. In the case of tab-delimited files, the fields cannot be distinguished. In both file types, the last field of the previous record and the first field of the next record run together.
It doesn't seem logical that java won't read in tabs/newlines/carriage-returns. Can someone tell me what's wrong? 
Thanks

Using the FileInputStream, is there anyway to read in multiple characters at a time, like a readline() function? I've looked at various buffered input streams and none of them seemed to have this function.

Problem reading data from textField?

I have a problem in my program I'm currently doing.
I have a textArea and a textField in a container.
Inside the textArea will be displayed some questions which require user to give answers to in the textField.
When user types something in the textField and presses enter, an actionListener will trigger and take in String.
My problem is how do you wait for the user to type something in the textField?
thanks

Problem reading data from database

Hi All,
I'm doing some test with Oracle Coherence, particulary testing partitioned cache of a database. I'm using a client/server archictecture and I developed my own CacheStore. So, the problem is, after start the server and the client, when i do a get() in the client for a object that is on database and not in the cache, the cache answer is it doesn't exist. Isn't it supposed the cache "call" the cache store and read/verify if it is on database?
My Configuration file:

You should use a fully qualified class name to enable the JVM class loader to find the RechargeCacheStore class.

Problem reading dates into numbers

I suspect I am missing something very obvious but I am trying to read a spreadsheet with dates in the first column into Numbers 3.0.1 in Mavericks. The original file was in xls format and the dates are imported as numbers (e.g. todays date - 31st Dec 2013 appears as 41639). The spreadsheet was created with Libreoffice but the dates are fine if I read the xls file into preview or google docs. I have tried reformatting the column into date format but nothing happens. Any ideas?

Check to see if any columns are hidden by opening the contextual menu for any column:

I'm getting the following errors:
java.util.NoSuchElementException     at java.util.StringTokenizer.nextToken(StringTokenizer.java:259)     at myClass.readFile(myClass.java:387)     at myClass.doPost(myClass.java:421)I am reading a file of the form:
Blah|blah2||
'|' is the delimiter. A null would just have another |
Here is my code:
public void readFile(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
          PrintWriter out = response.getWriter();
         String row;
         BufferedReader infile1 = new BufferedReader(new FileReader("c:\\file1.txt"));
         response.setContentType("text/html");
         String FName="",MName="",LName="",Sex="",Street1="",Street2="",City="",State="",Zip="",PhoneLocalCode="",PhoneAreaCode="",PhoneLastCode="",Email="",OtherInfo="";
        try {
                while ((row = infile1.readLine()) != null)
                  StringTokenizer in_str = new StringTokenizer(row, "|");
                  FName = in_str.nextToken();
                  MName = in_str.nextToken();
                  LName = in_str.nextToken();
                  Sex = in_str.nextToken();
                  Street1 = in_str.nextToken();

                  City = in_str.nextToken();
                  State = in_str.nextToken();
                  Zip = in_str.nextToken();
                  PhoneLocalCode = in_str.nextToken();

             } catch (IOException ioException) {
               out.println("Error: "+ioException);
             out.println(FName);
             out.println(MName);

Well, you are probably passing in a line that is tokinized into less than 14 tokens.
Add some debug output that prints the line that you are tokenizing.
Use hasMoreTokens and countTokens to determine if it is ok to call nextToken or if you are already out of tokens.
E.g. you could do something along these lines:
fixed token count formatprivate void tokenize(final String line)
final StringTokenizer st = new StringTokenizer( line, "|" );
if ( st.countTokens() != 14 )
     throw new RuntimeException("Invalid token count: " + st.countTokens());
FName = st.nextToken();
}variable token count formatprivate void tokenize(final String line)
final StringTokenizer st = new StringTokenizer( line, "|" );
if (st.hasMoreTokens())
    FName = st.nextToken();
if (st.hasMoreTokens())
    MName = st.nextToken();
}

A problem with data acquisitioning in LV 7.1 (transition from Traditional NI-DAQ to NI-DAQmx)

Hi to everyone,
I have a problem with data acquisitioning in LV 7.1.
I made a transition from Tradiotional NI-DAQ to NI-DAQmx in my LabVIEW application.
The problem I have is that when I acquire data in Traditional (without writing somewhere -
just reading) then there is no scan backlog data. But when I acquire data in application that
acquisition is based on DAQmx than a scan backlog indicator shows numbers from 20 to 50 for
about 6 min and then that number quite quickly increases until I get an error (unable to
acquire data. The data was overwritten).
Acquisition settings are the same in both cases. When I acquire with DAQmx I use a global
channels. Is a reason for that phenomenon in global channels data procesing? But it seems
strange why does it flows quite smoothly for about 6 min and then it stucks?
Best regards,
Ero

If you have an old Daq unit it may not be compatible with DAQMX. Which DAQ unit do you have? I think NI have a list showing which DAQ driver you can use with your card
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Having problem with adding and reading dates to/from database !!!

Hi
I am new in J2ME
I am trying to code a simple software.
My problem is with dates.
I have a datefield on my menu and the user will choose the date from here. By default, datefield shows todays date. But when I try to write that date to database using rms, date value transforms to java.util.Date@acfdb0fe.
As I read from tutorials this is common problem of date class, so I tried to use calendar class.
But with Calendar class I cannot let user to choose date from screen like DateField. datefield dowsn't work with calendar.
later, I will use that date for sorting records
Summary : I need a sample code that read date from screen (preferably with datefield), write it to recordstore. and then read it from recordstore asnd write to screen.
I searching internet for a sample code through days.
Please help me
Thanks

Hi,
The best i would suggest is instead of storing the date as 19 Jan 2004 or something like this better store the date in milliseconds.
DateField df = new DateField();
Date d = df.getDate();
long ms = d.getTime();
store the value of ms in RMS. This is the commonly used way to store date in RMS for j2me.
You can get back date using
Date d = new Date(ms);
DateField df = new DateField();
df.setDate(d);
Prabhu.
