Visualizzare lo stato ingressi con led boolean

Sono alle prime esperienze con Labview e una 6009 in particolare sto facendo prove con I/O digitali ed il loro controllo, per le uscite mediante pulsanti e la funzione build array ho creato un array e inviandolo all'ingresso data del daq assistant opportunamente impostato sono riuscito a pilotare le uscite.
Per quanto riguarda gli ingressi volevo visualizzare il loro stato mediante dei led sul pannello frontale, dopo aver configurato il daq assistant in digital line input dall'uscita data come posso indirizzare i segnali provenienti deli ingressi verso i led boolean?
Scusate per la banalità della domanda!

Ciao Giuseppe,
sono riuscito a realizzare ciò, aggiungendo quanto già chiesto nei test.Ti allego il VI (Spero possa essere utile per gli altri dato che utilizzo a volte questo forum per qualche idea).Adesso, vorrei però fare ciò, utilizzare il framework .Net con la libreria Labview .Se hai qualche consiglio, fammi sapere.
A presto!!!!!!!!!!!!!!

mi dareste una mano?
perchè non sò veramente come aprire il file.

It looks like you are already a Creative Cloud subscriber, so if your OS will support the 2014 version all you need to do is download and install it through the CC Desktop Application.

CAn I make a push button LED blink

Take the"modern" pushbutton control.
The LED on the control is on when the control is pressed (true) and off then false.
Can I make the LED blink when false and be on solid like normal when true?
I tried the property node "blink" but that kakes the whole control blink (and looks stupid)

Hi RTSLVU,
Here is another example of how you can cheat to get it done. It combines a custom Boolean LED and a regular Boolean Push Button. If you don't want to mess with custom controls, you can overlay a regular Round LED Boolean (stretching it out a bit makes it fit better) over the existing LED on the Push Button, it'll just look a little different.
Thank you for choosing National Instruments.

Why do boolean indicator outputs toggle when true is written repeatedly?

Hi,
I'm using an LED boolean indicator in a sub vi connected to an output terminal.
If TRUE is repeatedly written to it then it toggles between ON and OFF as though it were a push button switch and each TRUE received was someone pushing the switch.
If I disconnect it from the output terminal then it behaves as expected, staying ON if TRUE is repeatedly received.
Why does it do this, how can I fix it?
Also, how can I turn all breakpoints off collectively without removing them?
Thanks,
Dave G
(LabView V7.0)

Hi Dave,
go to File>>VI Porperties>>Execution and check if "Clear indiators if called" is checked.
If this is checked it clears the indicator when the VI is called. If you set the value to TRUE this value will be given back to the calling VI.
This behaviour was introduced to allow simpler programming. Think of a programm with various cases. There is only one case where you want to set the indicator to TRUE. If you haven't the above flag you need to set it to FALSE in all other cases. This forces to move the terminal outside of the case and to wire a lot of FALSE constants to the tunnel (nowadays we have the "use default if unwired" mechanism which makes the flag unnesseccary).

How to invisible LED in cluster from front windows

Hi guys,
I have cluster inside array1*8 it has three LEDs, sometimes i need one or two LEDs, so how to invisible extra LED from cluster.
I knew how invisible some buttons or string...etc. But my question how to invisible inside cluster that is inside array
Thanks and best regards.

OK Array of clusters containing "Invisible" controls-
Since all elements in an array must share all properties except value we need a solution where the value property controls visibility as far as users are concerned. LEDs (Booleans) are out-
BUT, if you used Color boxes instead of booleans you can set the value to "LED Off" "LED On" or "Transparent"

Ho comprato il 20 dicembre l'iPhone 5 in offerta dalla TIM. Da allora sono alle prese con il continuo passaggio dal 3G ad Edge. Fatto ripristino e reset di rete più volte, ma né la TIM né Apple riconoscono il problema, ma si rimpallano la responsabilità.

Ho comprato il 20 dicembre l'iPhone 5 in offerta dalla TIM. Da allora sono alle prese con il continuo passaggio dal 3G ad Edge. Per ritornare al 3G devo attivare e disattivare l'opzione "aereo" o "3G". Ho fatto il ripristino dell'iphone e il reset di rete della nano sim più volte senza concludere nulla, ma né la TIM né Apple riconoscono il problema, anzi si rimpallano la responsabilità. Che fare?

Facendo varie prove (come l'inserimento della nano sim in un cellulare Nokia) e confrontando il comportamento dell'iPhone 5 con un altro iPhone 5 - sempre con nano sim TIM - in zone diverse della città in cui abito (Palermo), sono pervenuto alla seguente conclusione: c'è un problema del dispositivo, ma c'è anche un problema di regolazione del segnale dal parte del gestore TIM.
Non sono un tecnico e non so spiegare perchè ciò avvenga, anzi mi piacerebbe saperlo sia dalla Apple che da TIM, ma dubito che dichiarino apertamente il problema. Se non si capisce perchè ciò avvenga, è inutile sostituire telefono e nano sim.
Io ho cambiato nano sim e il problema è rimasto. Ho avviato on line con un operatore Apple la pratica di sotituzione dell'iPhone: mi mandano un corriere a ritirarlo e me lo riportano in una settimana. Ma qui mi sono fermato e non ho proceduto ancora alla sostituzione, perchè mi è stato detto che mi sarebbe stato sostituito con un "rigenerato".
Come nuovo non è la stessa cosa di nuovo e in rete leggo di clienti che dopo la sostituzione continuano ad avere lo stesso problema.
Chiediamo a Apple di dirci con chiarezza se c'è una partita di iPhone 5 con qualche elemento difettoso o non adatto al mercato italiano o se è un problema di software (e in quel caso aspetteremo pazientemente un aggiornamento) e a TIM chiediamo di non blindare il 119. Infatti da alcuni giorni è impossibile contattare un operatore. Come mai? Subissata dalle lamentele dei clienti?
Ho molta voglia di rescindere il contratto di trenta mesi...

How to create and illuminate a multi-indicator?

Hello all!!
I'm a complete noob with LV and first post to the forum.
I'm hoping I can get some help in form of suggestions or links to examples, tutorials or somewhere to just research info on my problem.
ON the front panel, I'm needing to put some indicators, each of which look like the LED indicator...but have the capability to have 3 or more different states....rather than just the two offered by the boolean LED object.
A simple example of something like I'm trying to do, would be a single indicator for a stop light...having different colors and captions/lables for different states in my code:
RED-Stop
YELLOW-Caution
GREEN-Go
I'd looked under the graphs->controls palette..and seen a 2d picture control and when rt clicking on that in the block diagram area, I saw the option for Picture Palette Functions, and in there saw options for draw round....etc. But I'm not sure what to connect this to, or how to control it associated with the 2D picture object.
Is that the way I'd have to do this? If so...any suggestions where I could look for an example ?
If not this..what would be the best way I should try to look into doing this?
Thank you in advance,
cayenne
PS. I have Labview 2011

later versions have a round color box But, as shown below there are a few issues
First it lacks the shading. second it does not size the same as an LED boolean.
Well we can fix one of those the shading is easy enough to duplicate. Just copy the LED color area to clipboard and import it to the color control color area at same size. A little futzing with sizes and viola'.
The attached example uses a shading I prefer but serves to illustrate

Error executing a Oracle query when connection is fetched from Datasource

Hi Folks,
I am struggling with a rather wierd issue. The DBA of my application has exposed some function based view(not exactly sure what that means) which returns results like any query over a table. I am having a tough time consuming it in my java application. The name of the view is - `networknode_api.get_ftapp_networknode_hrchy` The SQL for it is(syntax might be a bit strange as there is actual word `table` in the query)
view plaincopy to clipboardprint?
Note: Text content in the code blocks is automatically word-wrapped
01.SELECT * FROM table (networknode_api.get_ftapp_networknode_hrchy('19-Feb-2013'));
SELECT * FROM table (networknode_api.get_ftapp_networknode_hrchy('19-Feb-2013'));
The query returns a hierarchical result data, provided below is a sample output (ignore the ouput if the formatting is too werid)
Parent_NODE | Child_NODE | NODE_DISPLAY_NAME | BEGIN_DATE | END_COB_DATE | LVL
null | CCN | Connent Node | 01/20/2013 | 10/19/2013 | 1

try {
InitialContext ic = new InitialContext();
//DataSource ds1 = (DataSource) ic.lookup("jndiDsFlex");
//Connection conn = ds1.getConnection();

java.sql.SQLSyntaxErrorException: ORA-00904: : invalid identifier
I debugged through the code and noted the driver and connection details that the connection object has embedded. Using that I wrote a sample java jdbc code-
public static void main(String[] args) throws Exception {
try {
//Class.forName("oracle.jdbc.driver.OracleDriver");
//Class.forName("weblogic.jdbc.rmi.Driver");
Driver myDriver = (Driver) Class.forName("weblogic.jdbc.jts.Driver").newInstance();
} catch (ClassNotFoundException e) {
System.out.println("Where is your Oracle JDBC Driver?");
e.printStackTrace();
return;
Connection connection = null;
try {
connection = DriverManager.getConnection(
"jdbc:oracle:thin:@//ssn20331020-rt.eu.prog.net:1522/NEXSERV",
"sample",
"sample1234");
} catch (SQLException e) {
System.out.println("Connection Failed! Check output console");
e.printStackTrace();
return;
Statement stmt = connection.createStatement();
stmt.execute("SELECT * FROM table (flex_compnode_api.get_ftapp_compnode_hrchy('19-Feb-2013'))");
ResultSet rs = stmt.getResultSet();
int i = 0;
while(rs.next()) {
String pNode = rs.getString("parent_node");
String cNode = rs.getString("child_node");
String dName = rs.getString("node_display_name");
System.out.println("Hello: "+i++);
The above code works perfectly fine. Also tried the above code using normal Oracle JDBC driver and too works fine. I am baffled; what goes wrong when using the connection from a DataSource object. Does the driver treat SQL statements differently based on how the connection object is obtained? Appreciate your inputs/comments for same.
The oracle db version is - Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
Application Server - Weblogic 10.3

Below is the stacktrace and the driver details which are same for both the standalone basic Jdbc program and one where connection is fetched through datasource.

Calling a method from another servlet? very beginner

I am going to try to explain what I want to do so just be patient please.
I want to call a method in a seperate servlet to connect and release my connection pool - How do I do this?
This is what I have been trying... help
dbPOOL.class
package DATABASE;
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
import java.util.*;
public class dbPOOL {
Connection con;
private boolean conFree = true;
private String dbName = "java:comp/env/jdbc/connectDB";
public dbPOOL() throws Exception {
     try {
              InitialContext ic = new InitialContext();
              DataSource ds = (DataSource) ic.lookup(dbName);
              con = ds.getConnection();
     } catch (Exception ex) { throw new Exception("Couldn't open connection to database: " + ex.getMessage());
public void remove () {
         try {
             con.close();
        } catch (SQLException ex) { System.out.println(ex.getMessage());}
protected synchronized Connection getConnection() {
         while (conFree == false) {
                 try {
                         wait();
                 } catch (InterruptedException e) {
              conFree = false;
              notify();
              return con;
    protected synchronized void releaseConnection() {
        while (conFree == true) {
                 try {
                    wait();
                 } catch (InterruptedException e) {
              conFree = true;
              notify();
}and my worker servlet connTest
package DATABASE;
import javax.naming.*;
import javax.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
import java.util.*;
public class connTest extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, SQLException, IOException {
         try {
                String selectStatement = "select * " + "from mt.Evendale_Web_Groups";
                getConnection();
                PreparedStatement prepStmt = con.prepareStatement(selectStatement);
                ResultSet rs = prepStmt.executeQuery();
                while (rs.next()) {
                   groupList gl = new groupList(rs.getString(1), rs.getString(2), rs.getString(3));
                prepStmt.close();
        } catch (SQLException ex) { throw Exception(ex.getMessage());}
            releaseConnection();
}When I try to compile the connTest servlet - I keep getting cannot find symbols errors on the methods. How do I fix this?

Which errors exactly?
Try something like this:
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
dbPOOL db = null;
try {
String selectStatement = "select * " + "from mt.Evendale_Web_Groups";
db = new dbPOOL();
Connection con = db.getConnection();
PreparedStatement prepStmt = con.prepareStatement(selectStatement);
ResultSet rs = prepStmt.executeQuery();
while (rs.next()) {
   // process your rs
prepStmt.close();
} catch (Exception ex) {
} finally {
    if (db != null)
         db.releaseConnection();
}Simply change the package name to something else. But don't forget to import your dbPOOL class since it is now located in a diff package. Also be aware of coding standards when naming your classes and packages.

Update problems, no space left on device (ZTE Open)

I just received a ZTE Open device in the mail today, and after playing around with it a bit, I noticed that every time I tried to check for system updates, it would show me one 13.xx MB update, which I downloaded, apparently applied, and the phone seemed to restart itself, but then I would be shown the same (??) update available. The phone is without a SIM card, just playing with it connected via Wifi, with the 4GB microSD card installed. Then, this evening, I got an error message, which apparently was recorded on the SD card, a file called recovery.log (contents follow):

The SD card also contains a zip file in updates/fota/update.zip, which in turn contains patch/system/P752D04_DEV_US_20130726.zip, which contains: amss.mbn (about 20 meg) and boot.img (about 4 meg).

Just jumping in here, I received mine on the 23rd and I am also seeing the same problem, but the logs are a bit different. Although, I am running OPEN_US_DEV_FFOS_V1.0.0'''B02'''. While the recovery log states B01.
I'll toss my log up as well so trends can be examined.

Digital Output With Timer (Simulation)

Hello everyone, I just learned how to make LabVIEW program a week ago. I try to make a simulation of Digital Output by LabVIEW (my attachment). In this simulation I have a slider as an input (0-10 V), two numeric control (upper limit and bottom limit), a waveform chart that plot those 3 value, and two boolean LED (P0.0 and P0.1) as an indicator. In this simulation you can fill any number (between 0-10) in the numeric control as a limit for your slider input. If the input from a slider exceed those upper and bottom limit then the boolean LED will turn on, P0.0 if exceed upper limit and P0.1 if exceed bottom limit. The problem is I don't know how to make timer for those boolean LED. As example:
1) Make an input from slider,
2) If input (1) exceed the upper limit,P0.0 will turn on for 5 second,then turn of for 10 second,
3) If in that 10 second you change the input back to normal (between upper and bottom limit) then P0.0 will stay turn of until the input from slider exceed the upper limit again,
4)If in that 10 second you didn't change the input (stay exceed the upper limit) then P0.0 will repeat the process (2) until you the input from slider back to normal.
(Same process for input that exceed the bottom limit).
Can you help me to make this timer? Thank You (I'm sorry I made a double post):newbie
Regards
Juventom

Digital Output With Timer.vi ‏16 KB

Hello Juventom,
As I understand it you want to be continuously checking the value of the sliding bar and comparing that to the upper and lower limit controls whilest also chaning the LED booleans to true for 5 seconds then false for 10 seconds if the sliding bar value is outside of the limits.
To do this you would probably be best using a parallel loop design, where you have 3 while loops in place of the one you have currently. Each one of these while loops would be responsible for a part of your program (e.g. the top one would display your values on the graph and the second one who check the sliding bar value against the upper limit and then turn on the LED, etc)
I've found this tutorial about multiple loop programs and I think you should look at the section entitled "Parallel Execution"
http://zone.ni.com/devzone/cda/tut/p/id/3749
This way you can use normal delay VIs but when they run they only pause that loop rather than the whole program.
Please let me know how you get on with this, and ask me if you need further help.

How to add an image file to Oracle db?

Need help urgently....Anybody knows how to add an image file (example: jpg)into one of the fields in Oracle database??

This will do the job..

Wanneer een request.getInputStream wordt geconferteerd naar een "String" (zie later) dan ziet de output in tekstformaat er als volgt uit:

Now when i come to the page for first time and select a row and click on Export then the filename that gets shown in save file dialog is incorrect (it shows partial adf taskflow name) , but when i select the row again by clicking on any other row and click export it shows correct filename i.e. selectedRowName.zip or .xml according to type of row selected.
Can anybody suggest what am i missing?

difficult to tell like this.but better you debug your code then you can get where you getting filename wrong.

ps>> I want to to use Generics to help it but I don't know how to do it in the right way . Can you you help me?
Thanks
Arunya

regarding your Map/LinkedHashMap, since you keys are String and you values are Objects... you would define you Map using those two as you data type pair...
ap<String,Object>thisRow = new LinkedHashMap<String,Object>();and similar for you List/ArrayList where you putting Maps into...
List<Map<String,Object>> rows = new ArrayList<Map<String,Object>>();for more information on generics read...

Question about running a servelt using HTML form.

Hi, Im new to Servlets , I have created a servelt with this code :
package oracle.servlets;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class LoginServlet extends HttpServlet {
 private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
 private static final String DB_URL = "jdbc:oracle:thin:@localhost:1521:ahmaddb";
 private static final String DB_USERNAME = "fundinfo";
 private static final String DB_PASSWORD = "tadapps";
 private static Connection con;
 private String pass;
 private String name;
/*init() : invoked by the servlet engine before the servicing of client requests
- Can be used to retrieve initialization parameters
Takes a ServletConfig object as a parameter
Is invoked when the servlet instance is created
Is useful for obtaining database connections from a connection pool*/
 public void init(ServletConfig config) throws ServletException {
 super.init(config);
 //config.getInitParameter(arg0);
 public void doGet(HttpServletRequest request,
 HttpServletResponse response) throws ServletException,
 IOException {
response.setContentType(CONTENT_TYPE);
 //PrintWriter : Print formatted representations of objects to a text-output stream.
 //getWriter() : Returns a PrintWriter object that can send character text to the client.
 PrintWriter out = response.getWriter();
 out.println("<html>");
 out.println("<head><title>My First Servlet</title></head>");
 out.println("<body>");
 out.println("The servlet has received a GET. This is the reply.");
 out.println("</body></html>");
 out.close();
 public void doPost(HttpServletRequest request,
 HttpServletResponse response) throws ServletException,
 IOException {
 response.setContentType(CONTENT_TYPE);
 PrintWriter out = response.getWriter();
 name = request.getParameter("user_name");
 pass = request.getParameter("user_password");
 boolean result = verifyPassword(name, pass);
 out.println("<html>");
 out.println("<head><title>LoginServlet</title></head>");
 out.println("<body>");
 if (result == true){
 out.println ("Hello " + name + ": Your login module is working great!");
 else{
 out.println ("Invalid user name or password");
 out.println ("</body></html>");
 out.close();
 // out.println("The servlet has received a POST. This is the reply.");
 //out.println("</body></html>");
 //out.close();
 public void configureConnection() throws SQLException {
 try{
 Class.forName("oracle.jdbc.OracleDriver");
 con = DriverManager.getConnection(DB_URL, DB_USERNAME,DB_PASSWORD);
 con.setAutoCommit(true);
 catch (Exception e){
 System.out.println("Connection failed: " +e.toString());
 public Connection getConnection() throws SQLException
 configureConnection();
 return con;
 protected boolean verifyPassword(String theuser, String password) {
 String originalPassword = null;
 try {
 con = getConnection();
 Statement stmt = con.createStatement();
 stmt.executeQuery("select password from login where uname='"+theuser+"'");
 ResultSet rs = stmt.getResultSet();
 if(rs.next())
 //>>
 originalPassword = rs.getString(1);
 stmt.close();
 if(originalPassword.equals(password)) {
 return true;
 else {
 return false;
 catch (Exception e){
 System.out.println("Exception in verifyPassword()="+e.toString());
 return false;
}and created an HTML form to target this servlet
<form action="/loginservlet" method="post">,
when I enter the the credintials I get this output in the webpage :
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
