Is it possible to get the current output level??

Is it possible to get the audio output level of a stream (in this case a mic input going through GSM compression to an RTP socket).
I would like a couple of volume bars in my application so people can see how loudly they are talking.
If anyone has any ideas on how to achieve this it would be much appreciated!
Thanks,
Dex

You want a volumeter, i am also interesting in it

DSC Alarms: how to get the current alarm levels / setpoints

I have a VI that can get the alarm levels for shared variables as they are set in the project library.
But I have programmatically changed the values for the alarm levels, so the Distributed System Manager shows different levels as compared to what my VI displays. I want the updated or current alarm levels - the ones that are retrieved by Read Alarms (called setpoints).
I could use Read Alarms, but that only shows the shared variables that are in alarm. I want all the shared variables in a process that is currently deployed.
Any suggestions?
BTW, is Distributed System Manager the same tool as Shared Variable Monitor? I can't find the Shared Variable Monitor on my system.

Hi Gretchen,
To answer your second question first, Shared Variable Monitor was the old name for what became Distributed System Manager. There was also some added functionality beyond just shared variables with DSM, so the name got changed.
As for suggestions regarding your application, I could use a little bit of clarification. I understand you're programmatically changing the alarm values and you want to display the values of your shared variables and their respective alarm states, correct? Also, when you're running your VI DSM does not update with the new alarm values (what happens when you hit the refresh button?).
I found a couple examples that may be useful moving forward Example 1, Example 2. These cover using shared variables and DSC's alarming features.

How can I get the current user and the current page?

Hi everyone
Question..
It is possible to get the current user (from the user's database on apex) and the current page? (I mean, if I'm in page 4 be able to query a variable / function or something which could give me the current displayed page)
Thank you very much... I'd been researching without success :-S so I'll appreciate your help
Regards,
Fury

Fury,
If the user has authenticated, :APP_USER is the name that was used. The current page id is in :APP_PAGE_ID.
Although I showed bind variable notation for those, & substitution format and v() notation are also available for referencing developer-defined items or built-in names. See the User's Guide for more details.

Getting the current row in a datatable

Hi,
I am using datatable. How do I get the current row in the datatable
and use it for my processing in the JSP page
or I want to just output that value with out using any jsf tags.
Examples
<h:dataTable styleClass="dataTable" id="table1" border="0" value="#{myTrainingHandler.myMediaTraining}" var="dataIt">
<h:column id="column1">
<f:facet name="header">
<h:outputText styleClass="outputText" value="Course Name"id="text1"></h:outputText>
</f:facet>
<!---------------------------------------------- how do I get the value of #{dataIt.name} and use it in the JSP way
Reason: I just want to output the value. If I am using h:outputText then it inserts <span>... </span>
or, I want to transfer that value to another another attribute in the session or something like that.
---------------------!>
<h:outputText styleClass="outputText" id="text2" value="#{dataIt.name}"></h:outputText>
</h:column>
</h:dataTable>
-Aswath

It looks like good idea!Unfortunately this is just workaround. Indeed your
suggestion is real JSF-feeling solution but due to the
bug (or rather pure design of RI implementation???) it
is dangerous.
I had some doubt about is it bug or my incompetence.
Unfortunately this seems is really bug.
Hope this problem will be solved in the next releases.from blueprints catalog:
Component bindings (e.g. <h:inputText binding="#{MyBean.lastNameComponent}" />) should always be stored in request scope since their value is no longer valid after a request has been processed anyway. The component tree is reconstituted during each incoming request, changing the physical instances these component bindings will point to.
as you see there is really problem in using session backing bean with component binding
so that means idea with parameter looks better now because we don't need to use table binding.
Or probably we can define some kind of pattern like couple of beans with request scope and session scope.
for example:
Catalog - session scope
CatalogView - request scope
Catalog will keep session data and CatalogView will provide some presentation logic (including some stricly visual oriented data) and access to business methods of Catalog class.
I will send you example by e-mail (on friday) if you not mind.

Thank you for your suggestion!
Probably I will use your idea in my application.
By the way I'm from Kiev also.Hello from Kiev :-)
I have one suggestion.
I'm working on JSF form that suppose to add, editand
delete records from table.
Also I wanna to use scrolling by page and sorting.
I'm trying to make this form somehow clean and
universal as much as possible.Seems I have same tasks for now.Great! I will send some code soon.
And maybe we can discuss every aspect how to do good JSF based application including config oriented information and utilities classes.
-how do you work with tables without primary keyI dont' have tables without primary key :)
-how do you make pagination by universal wayWe need just make good component for that.
We already started in this direction.

Getting the current time and comparing it to a time in the future

Hello,
I am seeing in my research some debate on the best way to get the time. I am reading that just using the Date class and calling getTime() is not the most reliable way to do things. Overall, I am trying to get the current time down to the millisecond. I then want to add 5 seconds to that time and then store that value. FInally, when the current time is greater or equal to this stored value, I want to continue on in my program. Can anyone point me in the right direction on how to calculate the time variable? Any help would be much appreciated. I am new to the JAVA world.
Thanks,
Tim

To store the current time, simply use new java.util.Date(). Yes, there might be slight inconsistencies and it might not be the most accurate time possible, but without significant additional effort (perhaps a native O/S call or the use of another time library), you will not do much better. Calendar won't help in this instance either. The easiest way to get five seconds in the future is to do the following:
Date now = new Date();
Date future = new Date(now.getTime() + 5000);To store and retrieve the value, it depends on what you are doing. You can place it in the database via JDBC (BTW, if you trust the database timestamp more than Java's you can use something like Oracle's SYSDATE instead of Java's date in your SQL query). You can place it in the filesystem. You can store it in the user's session.

How to get the current date in standby display?

My N73 ( 3.0705.1.0.31 ) displays the current date/day only in the general profile. When I switch to any other profile, that place is taken over by the profile name.
Is it possible to get the date/day displayed in a non general profile?
If it is otherwise, the 240x320 display is of little use...

That's the way it goes. In addition you see the date/time on the screensaver with every/any profile.

Get the current time

Hi I was wondering how I can get the current time and use is to compare it e.g. in a IF sentence.

Hi I was wondering how I can get the current time and
use is to compare it e.g. in a IF sentence.This might help. I'm not exactly sure what you are asking for but I use this type of code to compare the current time to my start time in my program, specifically for my loggerformatter. The output shows the seconds and the remainder in milliseconds. The efficiency is probably suspect, but it might give you some ideas... Joel

import java.text.NumberFormat;

        return((calEnd.getTime().getTime() - calBegin.getTime().getTime()) / 1000);

Get the current client-user password

Hello,
I implement the following code:
IWDClientUser user = WDClientUser.getCurrentUser();
String name = user.getFirstName() + " " + user.getLastName();
that works without any problems.
But I need also the password of the current client-user.
Is it possible to get the password?
Patrick

Patrick,
you mean a "login"? the hash-value won't help you, because as Dominik already mentioned: it's a <b>one-way</b> has, that means you can derive the hashcode from the password and not vice versa.
your solution would be e.g. to implement a saplogonticket authentication in your second web-server.

GregorianCalendar - getting the current date

Hi,
Have any of the Calendar classes been changed in version 1.5. I'm trying to get the current date and time in an application, to add to filenames when they are backed up. In java 1.4 the following code was sufficient to get the information required:
GregorianCalendar cal = new GregorianCalendar();
filename = "C:\\Program Files\\Apache Group\\Apache2\\www\\test\\htdocs\\backups\\";
filename += theFile;
filename += "=" + getUser() + "=" + cal.get( Calendar.HOUR_OF_DAY ) + "_" +
     cal.get( Calendar.MINUTE ) + "=" + cal.get( Calendar.DAY_OF_MONTH ) + "_" +
     ( cal.get( Calendar.MONTH ) + 1 ) + "_" + cal.get( Calendar.YEAR );
I'm writing another app using the same code and SDK 1.5, but it's returning the same values every time.
Cheers
Matt

I wrote a small program to test the Calendar object on my system:
import java.util.*;
import java.awt.event.*;
import java.awt.*;
public class Tester extends Frame implements ActionListener
     public Tester()
          javax.swing.Timer timer = new javax.swing.Timer( 1000, this );
          timer.start();
          setSize( 400, 400 );
          show();
          addWindowListener(
               new WindowAdapter()
                    public void windowClosing( WindowEvent e )
                         System.exit( 0 );
     public void actionPerformed( ActionEvent e )
          Calendar cal = new GregorianCalendar();
          System.out.println( "Time: " + cal.HOUR + ":" + cal.MINUTE + ":" + cal.SECOND );
     public static void main( String args[] )
          Tester t = new Tester();
This repeatedly outputs:
10:12:13
I tried this with Calendar and GregorianCalendar. Both of them do not seem to work. I'm not using the same Calendar object, or outputing in the same second....

How do I get the current ios for ipod

my iPod touch has ios 4.2.1 and it keeps telling me I have the most up to date software. How do I get the current version?

It sounds like you may have a 2nd generation iPod Touch, in which case 4.2.1 is the highest possible iOS. Please check the model number on the back, A1288 is 2nd generation.

How to get the current filename and & or path

How can I get the current path or filename?
I didn't really find any answers in the net. this.path or app.path were suggested but I couldn't get it to work.
Thanks in advance for your answer!
Livecycle Designer ES 8.2.1.3144.1.471865

Hi,
event.target.path.toString(); will give the full path including the filename.
event.target.documentFileName.toString(); will give the filename only.
Good luck,
Niall

How to get the current path of my application in java ?

how to get the current path of my application in java ?
thanks

To get the path where your application has been installed you have to do the following:
have a class called "what_ever" in the folder.
then you do a litte:
String path=
what_ever.class.getRessource("what_ever.class").toString()
That get you a string like:
file:/C:/Program Files/Cool_program/what_ever.class
Then you process the result a little to remove anything you don't want:
path=path.substring(path.indexOf('/')+1),path.lastIndexOf('/'))
//Might be a little error here but you should find out //quickly if it's the case
And here you go, you have a nice
C:/Program Files/Cool_program
which is the path to your application.

I've recently been given a macbook pro from uni, with lots of adobe software on. I want to pair it with my iMac which has music etc and is it possible to get the software to the imac and the files to the macbook?Giving me the best of both :-)

I've recently been given a macbook pro from uni, with lots of adobe software on. I want to pair it with my iMac which has music etc and is it possible to get the software to the imac and the files to the macbook?Giving me the best of both :-)

You would need the original installation disks or files for the Adobe software to get it onto your iMac, and having it on two computers may not be allowed by your university's licensing. Talk to whoever issued the MacBook.
As to the music, just copy it over to the MacBook, either via Home Sharing, file sharing, or an external storage medium (hard drive, USB flash drive, etc.).
