An expression to Count up, to use in conjunction with Soundkeys?

I am able to get soundkeys to output a 1 every time a certain audio freq. hits, but I don't know how to get it to add 1 each time it hits? currently it just goes back to zero when the freq. is not present, but I want it to count 1, 2, 3, and so on each time the audio hits.
Is there an expression someone knows about that could help me with this?
Thanks all!
Aza

Set the Falloff parameter for that output to "None(Integrate)".

What is the best stereo expander software to use in conjunction with OS X Mountain Lion?

All-
Have got a 13" MacBook Pro running Mountain Lion, and am trying to find a great simple stereo/3D/4D type of sound expander software plugin/app to use in conjunction with iTunes and with my computer games. I used to use Astound Sound, by Genaudio, on my earlier Macs...but their site states that they are no longer updating the app...and haven't done so for three years now. Any suggestions?
Thanks-

Get rid of Norton a/k/a Symantec. It is one of the worst pieces of trash you can install on a Mac.
You do not need any additional anti-virus software than is already designed into OS X to protect your Mac against malware. I assume you paid enough for your iMac and that's part of what you paid.
If you use Windows, or are concerned about harboring viruses that target Windows, or care about friends who use Windows, then get ClamXav. It's in the App Store and it is free.
Since friends don't let friends use Windows, I have no use for it.

GUIBB Form used in conjunction with IF_FPM_TRANSACTION

Hello,
I looked at the sample GUIBB Forms with provision to save the data in the form. It seems to me that it is not possible to use the interface IF_FPM_TRANSACTION in conjunction with GUIBBs. Is this true, otherwise, how do we incorporate the interface IF_FPM_TRANSACTION, say into the feeder class of GUIBB Form, i.e. IF_FPM_GUIBB_FORM ? Thank you.

Hah!, well, I suppose that's to be expected. We're putting seriously powerful technology in the hands of everyone with a few bucks to spare; it's inevitable that some oddball uses are going to crop up. When I think about the things one could do with an iPhone - without all that much skill or effort, even - it kinda gives me the willies.

GR based IV used in conjunction with Evaluated Receipt Settlement question

If we are using GR based IV, does the ERS process use the value of the goods receipt to create the invoice?

Yes, ERS will take the value of the goods receipt to create the invoice, which is why you only want to do ERS with trusted vendors.

App used in conjunction with accessory to turn iOS device into gun scope

Hi,
I recently came across the following product:
http://inteliscopes.com/
While I realize that using the iOS camera for "mock shooting" applications is completely innocuous, I think that using the iPhone attached to a semi-automatic weapon to aim and shoot crosses a line.
I'm curious if the use of an iOS device in ths manor violates any known terms of services, and if Apple has a known position on apps of this sort. Thanks.

PM Refurbishment Process used in conjunction with RLM (Remote Logistics Man

Hello Experts,
I was wondering whether anybody had any insight or experience in making use of the PM refurbishment process inconjunction with the remote logistics management module? Linking between offshore Refurb order to onshore and then to vendor etc?
Any insight would be most appreciated.
Thanks
Ross

Thanks for responding and it is IS OIL. The current process is to apply a negative QTY to the material on the PM order to ship it from offshore ot onshore. Then onshore the repair is handled via use of a service purchase order with a free charge item and a service line for the repair.
i am looking into making use of a refurbishment pm order at some point (instead of the initial work order or as opposed to the service PO) and was wondering whether you have any info with regards to how to use. Storage location movements offshore>onshore>vendor storgae location etc??
thanks

CR Server 2008 / Using openDocument interface with a no-logon wrapper

Hi, all!
I had a problem with the openDocument.jsp interface and a no-logon wrapper which took me quite a while to figure out. I'm now posting these results here in the hopes that someone else will find them useful. Of course, if anyone has input how to improve the solution, it's also welcome!
The system on which this was developed and tested was a vanilla Crystal Reports Server 2008 installation on Tomcat / MySQL / Windows Server 2003.
The problem was that calls to openDocument interface left sessions open and this quickly led to the situation where all the concurrent access licenses (CALs) were used. It seemed nondeterministic when a session was released; it could have been minutes or hours.
The solution: write a HTTP session timeout listener which logoffs the CRS-backend session. (The code below has still some dubug output enabled.)
package fi.niscayah.util;
import com.crystaldecisions.sdk.framework.IEnterpriseSession;
import javax.servlet.http.*;
import java.util.Date;
import java.util.Enumeration;
import java.text.SimpleDateFormat;
public class KillSession implements HttpSessionListener
    public void sessionCreated(HttpSessionEvent event)
        debug("sessionCreated()", event);
    public void sessionDestroyed(HttpSessionEvent event)
        HttpSession session = event.getSession();
        try {
            java.util.Enumeration name = session.getAttributeNames();
            while (name.hasMoreElements()) {
                String attributeName = (String)name.nextElement();
                Object attribute = session.getAttribute(attributeName);
                if((attribute != null) && (attribute instanceof IEnterpriseSession)) {
                    debug(" attribute : " + attributeName);
                    debug(" type      : " + attribute.getClass().getName());
                    IEnterpriseSession ies = (IEnterpriseSession)attribute;
                    ies.logoff();
            debug("sessionDestroyed()", event);
        } catch (Exception ex) {
            debug("sessionDestroyed() exception");
    private void debug(String msg)
        SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");
        String timestamp = sdf.format(new Date());
        System.err.println("[KillSession] [" + timestamp + "] " + msg);
    private void debug(String msg, HttpSessionEvent event)
        HttpSession session = event.getSession();
        String id = session.getId();
        String context = session.getServletContext().getServletContextName();
        debug("[" + context + "] [" + id + "] " + msg);
(If you want to test the above code, create a .jar package out of it and put it in webapps/OpenDocument/WEB-INF/lib.)
Next we need to register our listener. I noticed that the openDocument-webapp's web.xml-file already contained a listener definition that claimed to expire enterprise sessions on HTTP timeout. I never saw such results; I tested it by registering my own listener, which only outputted debug information, and then when ever a session timeout happened, I checked the amount of licenses in use via the CMC - it never dropped predictably.
So, comment out the SessionCleanupListener and add KillSession.

<listener>
    <listener-class>fi.niscayah.util.KillSession</listener-class>
</listener>



After the above, change the HTTP session timeout to something more suitable. If you're creating really big reports, one minute might be too little. Also notice, that the value is an approximation. The timeout event might happen just as one minute has passed, but usually it takes more.
<session-config>
    <session-timeout>1</session-timeout>
</session-config>
Now we're good to go and test the openDocument interface. The result should be that every time a HTTP session timeouts, an enterprise session (which was initialized via the openDocument call) is logged off.
Next the no-logon wrapper.
I found a lot of examples for logging in automatically, but every one of them exhibited a strange behavior (at least when used in conjunction with the openDocument interface) where the session count was increased by two. A lot of head scratching later, the solution below was devised.
<%@ page language="java"
    import = "com.crystaldecisions.sdk.framework.CrystalEnterprise,
              com.crystaldecisions.sdk.framework.IEnterpriseSession,
              com.crystaldecisions.sdk.framework.ISessionMgr,
              com.crystaldecisions.sdk.exception.SDKException"
%>
<%
ISessionMgr sessionManager = CrystalEnterprise.getSessionMgr();
IEnterpriseSession entSession = sessionManager.logon("Guest", "", "<server>:6400", "secEnterprise");
String entToken = entSession.getLogonTokenMgr().createWCAToken("", 1, 1);
// So that this can be logged off when the session timeouts
HttpSession httpSession = request.getSession();
httpSession.setAttribute("nologon_SESSION", entSession);
String query = request.getQueryString();
String redirectURL = "http://<server>:8080/OpenDocument/opendoc/openDocument.jsp?" +
    query + "&token=" + entToken;
response.sendRedirect(redirectURL);
%>
You can put the above .jsp-file where you like, but I dropped it in webapps/openDocument, since it's no use by itself.
The use of nologon.jsp is simple: use it as you would openDocument.jsp.
And there you have it. A word of warning though, if you're not sure what you're doing, I wouldn't recommend trying these things out. And you certainly shouldn't deploy these on a production environment.
As said before, any input is welcome!

I'll comment on the BusinessObjects Enterprise logon tokens that you may generate via the Enterprise SDK.
DefaultToken - this is used for failover - i.e., if the original EnterpriseSession object is destroyed without having logoff() method invoked, the failover can be used to re-connect to Enterprise without redo-ing authentication. This token is immediately invalidated with EnterpriseSession.logoff().
CreateLogonToken - token represents an EnterpriseSession independent of the original EnterpriseSession that generates it. So you should generated the CreateLogonToken and log off the EnterpriseSession before using the token, or you'll have two licenses being used.
CreateWCAToken - the Web Component Adapter token - this token is tied to the EnterpriseSession used to create it. If this EnterpriseSession is invalidated, the WCA token can no longer be used. Since this is essentially re-use of the original EnterpriseSession, license count is not increased with its use.
So in your application, you're generating the WCA Token, and using the Session Listener to explicitly log off the originating EnterpriseSession. The SessionCleanupListener is for cleaning up sessions created within InfoView on Web Application Server Session timeout.

Ted Ueda

Using Iphoto 8 with Aperture 3

I'm hoping that someone can help me with this one... I have sucessfully imported my existing Iphoto events (Iphoto 8) located on an external HD to my aperture library (on my Mac HD) as referenced files. I then created a new event with new photos imported from my camera on Iphoto, but can't seem to get this new event to Aperture as referenced files. I can import the masters from this event into the Aperture library, but don't want to do that for HD space issues. Basically, I'm still hoping I can use Iphoto as my main repository for photos (on my external HD) imported from my camera, view them quickly, then export a new iphoto Event to Aperture as I need to, but keeping the import as referenced files. I was hoping that Aperture would automatically update the library with new Iphoto events, but I can see the downside of this too. Hope this makes some sense and perhaps someone out there can help! SNNS.

There is no way to do what you want. You would need to import the photos from iPhoto as Managed, then use the 'Relocate Masters' command to move those out of there again.
Basically, I'm still hoping I can use Iphoto as my main repository for photos (on my external HD) imported from my camera, view them quickly, then export a new iphoto Event to Aperture as I need to,
Why?
The inverse is actually much easier. Import to Aperture (using Referenced Masters as you want) then share your Previews with iPhoto.
Remember, Aperture is not designed to be used in conjunction with iPhoto. It's a replacement for it and the various tools included are to facilitate moving from iPhoto on to the more powerful app.

Using Muvo^2 with naps

I have a Muvo^2 and Napster says that it is a Windows Compatible device and as such can be used in conjunction with Napster. I've tried all the logical things and consulted all the FAQs to try and put tracks onto it though, from Napster, but to no avail
Any clues anyone? Thanks

The player isn't compatible with subscription music such as Napster To Go. You can only use it with pay-per download type of online music. Also, for these type of music, you will need to use either Windows Media Player or MediaSource to transfer it to the player.

Using DB_ENV- failchk with BDBSQL

I have a multi process environment wiht BDBSQL. I have a single process that updates the database and multiple processes that read the database.
My goal is to have no impact on the writer process or reader proceses if one of the reader process fails. Has anyone configured BDBSQL for this kind of usage.
Is it possible to get this behaviour by using DB_ENV->failchk to clear up the read locks in case of process fialures.
Thanks for your help.

Hello,
Perhaps someone will have more information, but I think
this could work. If you find a problem let us know.
Make sure to check the documentation on "Architecting
Transactional Data Store applications", at:
http://download.oracle.com/docs/cd/E17076_02/html/programmer_reference/transapp_app.html
And also note the requirements for using DB_ENV->failchk documented at:
http://download.oracle.com/docs/cd/E17076_02/html/api_reference/C/envfailchk.html
For example, DB_ENV->failchk must be used in conjunction with DB_ENV->set_thread_count(),
DB_ENV->set_isalive(), and DB_ENV->set_thread_id().
Thanks,
Sandra

PL/SQL Counter for HTMLDB - Application Express - Survey Counter

I wonder if somebody could help me to clarify the HowTo on this Survey.
Based on:
http://www.oracle.com/technology/products/database/application_express/index.html
http://www.oracle.com/technology/oramag/oracle/06-mar/o26browser.html
I follow up however that is not exactly what I like to see in my Survey. I like to make something more elegant and flexible.
On this example he put 10 questions/ page. I like to use 1 Question / Page.
And I like to extend to more than 10 pages. for example 20.
My question to the forums is:
If I create an application with Only 3 pages [ Welcome, Survey, End ]
And the main page for the Survey is the second page.
How would programatically be the logic to:
Start the Welcome page => Setup variable counter = 1
Then using sessions with a button click on Start Survey.
Survey Page check for the existence of counter variable if exist retrieve the Question from the Questions table and the properly Answer will be recorded.
This answer could include comments, and the Rating could be an LOV.
After the Question 1 is asnwered then the Next Button on the Page 2 Call the same page 2. If the Questions is the max number of questions [20] then go to the End or Summary Page. if not just increase the counter variable then retrieve the next question.
Am I asking to much ???. I'm just starting on PL/SQL and HTMLDB I'm not sure how to manipulate those variables. I've been trying but I'm stuck.
Thanks in Advance for your Help.
Dino.

How do I use a DAC with my Airport Express ?

Hello,
Can I use a DAC with Airport Express ? If yes, how ?
TIA

check out this CNET Crave article: Using Apple's AirPort Express with a DAC: A how-to guide

Can AirPort express be used for AirPlay with my home stereo, and to give my Xbox 360 a WIRED internet connection via ethernet, simultaneously?

I am considering buying an airport but I am not sure if it will work how I would like it to. I need it for two things. The first would be to use for AirPlay with my home stereo. The second would be to use as a way to give my Xbox 360 a WIRED internet connection via the ethernet port. I would like to do these things simultaneously, rather than constantly changing the configuration and being limited to a single function each time I do so.
Thanks!

The 802.11n AirPort Express Base Station (AXn) can be configured as a wireless Ethernet bridge. In this configuration, it would join an existing wireless network and its Ethernet port would be enabled for a wired client, like your Xbox 360. This configuration would also support AirPlay simultaneously.

How to use TRUNC function with dates in Expression Builder in OBIEE.

Hi There,
How to use TRUNC function with dates in Expression Builder in OBIEE.
TRUNC (SYSDATE, 'MM') returns '07/01/2010' where sysdate is '07/15/2010' in SQL. I need to use the same thing in expression builder in BMM layer logical column.
Thanks in advance

use this instead:
TIMESTAMPADD(SQL_TSI_DAY, ( DAYOFMONTH(CURRENT_DATE) * -1) + 1, CURRENT_DATE)

Is ABAP expression FORM - PERFORM can be used in SAP BI 7.0 transformation

Hello
Is ABAP expression FORM - PERFORM can be used in SAP BI 7.0 transformations or method odf class is a recommended approach?
Thanks

SAP BI 7.x Transformations use OO ABAP where the logic that you enter into the tranformational routines (Start Routine, Characteristic Routines and End Routine) are inside METHODS. PERFORM and FORM are procedural-based ABAP and cannot be used in METHODS.
CLASS-METHOD and Function Modules are your best bets for processing outside of the transformational routine. As for performance, we use both and haven't found any signicant difference between the two (our custom Function Modules usually perform only slight better than our custom METHODS).
