Think before creating anything.What is the purpose of creating a time picker in jsp instead of javascript? If there are no special purpose then go for javascript to save the implementation time.

   function showState(str){
       if (typeof XMLHttpRequest != "undefined"){
           xmlHttp= new XMLHttpRequest();
       }
       else if (window.ActiveXObject){
           xmlHttp= new ActiveXObject("Microsoft.XMLHTTP");
       }
       if (xmlHttp==null){
           alert("Browser does not support XMLHTTP Request")
           return;
       }
       var url="getprice.jsp";
       url +="?count="+encodeURI(str);
       xmlHttp.onreadystatechange = stateChange;
       xmlHttp.open("GET", url, true);
       xmlHttp.send(null);
   }

   function stateChange(){
       if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
           document.getElementById("price").innerHTML=xmlHttp.responseText
       }
   }

Audio Sample Playback

Re: Audio Sample Playback

7-Mar-13 15:46

I'm trying to find a good source of information on how to playback audio samples in java. Preferably with source code examples that I could learn from.

The sample durations are too short to be kept in individual files because of the time taken to load them.

So the idea is to playback samples that are equally spaced within one monolithic audio file.

It doesn't seem like an impossible task, but finding information on java audio (all in one article) has been difficult.

A. Why yes, it's celery or tomato.

This is my first Java database application so I'm sure I'm missing something. This is the code I have...

Java

import java.sql.*;

public class ClsConn {
    private Connection conn;
    
    public Connection openConn() {
        try {
            System.out.println("Trying the connection now...");
            //Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            Class.forName("net.sourceforge.jtds.jdbc.Driver");
            //conn = DriverManager.getConnection("jdbc:odbc:IntranetSql");
            conn = java.sql.DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433;databaseName=Intranet;user=sa;password=passwrd");
            System.out.println("DSN Connection ok.");
        } catch (Exception e) {
            System.out.println("DSN Exception: " + e.getMessage());
            e.printStackTrace();
        }
        return conn;
    }
}

This was originally using a DSN, but that didn't seem to work (I was getting some interesting behavior) so I've gone to what you see there. I'm getting this error message: Cannot open database "Intranet" requested by the login. The login failed.

For reference on the same server for my asp pages I have the following which is working:

Public Function OpenConnection() As Boolean
       Dim connString As String
       cnn = New SqlConnection
       connString = "server=localhost; uid=sa; pwd=password; database=intranet"
       Try
           cnn.ConnectionString = connString
           cnn.Open()
           Return True
       Catch ex As SqlException
           GlobalClasses.Client_Alert(ex.Message)
           Return False
       End Try

   End Function

I have opened up 1433 on the server so I have no idea what's going on... Any ideas would be greatly appreciated...

--Update 1--
For "fun" I just changed the Database to "Master" and the gosh darn thing "works"... well my query fails because the table it's looking for isn't in Master but the connection is working. I really need to start drinking or something. So it appears that everything is working for for some reason I can't see the database???

--Update 2--
Ok so I change my query figured that would be a good idea right? Nah... So I put in "use Intranet SELECT...." and get "Exception: Database 'Intranet' does not exist. Make sure that the name is entered correctly.". So I did what any good frustrated developer would do and opened up the mgmt studio for SQL Server and went to master and ran the same exact query with the "use..." (yes I cut and pasted it in just to be 100% sure) and imagine that it works. Yet my Java application is still saying it doesn't exist.
I am trying to figure this out not just waiting for an answer... Big Grin | :-D

--Update 3--
Connection string is now:
conn = java.sql.DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433/master;user=sa;password=passwrd");

Re: jtds connection problem.... SQL Server 2012 Express

Hello,

try specifying the instance parameter in connection string. Following text is extracted from the JTDS FAQ.

SQL Server can run multiple so-called "named instances" (i.e. different server instances, running on different TCP ports) on the same machine. When using Microsoft tools, selecting one of these instances is made by using "<host_name>\<instance_name>" instead of the usual "<host_name>". With jTDS you will have to split the two and use the instance name as a property.

Regards,

Prasad P. Khandekar

Bonjour,
j'ai un projet qui doit obligatoirement utiliser le système immunitaire artificiel comme méthode de classification.
j'ai déjà posé mes questions sur d'autres forums, mais il n'y a pas grand nombres de personnes qui ont utilisé ce procédé.
Donc svp, quelqu'un à t-il déjà utilisé l'AIS ?
je depend de vos aides s'il vous plaît pour réaliser mon projet intitulé:

" Application du système immunitaire artificiel pour la reconnaissance de
formes'' l’Écriture arabe "
et merci

I'm not sure what you are asking here, but if you want someone to provide you with a ready made answer then you will be disappointed.

Je ne suis pas sûr de ce que vous demandez ici, mais si vous voulez quelqu'un pour vous donner une réponse toute faite, alors vous allez être déçu.
