How do I create a thresholding function for a 2-D waveform, little to no experience is driving me crazy?
Hello All,
I could really use some help here. I have very little experience with LabView and I am trying to create a threshold detector that outputs a boolean value once the threshold is crossed. I am getting a 2-d waveform in from my daq, that part was easy, I am trying to do this in real time and point by point. Ultimately once the threshold is crossed I need a true to go to a while loop which will then perform another operation. I am running LabView 8.0 and could really use the help to get this threshold figured out. Thank you very much, if any further information is required please feel free to let me know.
I really appreciate it,

There are many ways of detecting thresholds. Below are a few examples. Remember that the data to the graph is often an array of numerics (doubles - usually). So simply make use of array functions or comparison functions. Many math functions are polymorphic and work very well with arrays. So do boolean functions.
Have a look at the three examples below. Hopefully they will help.

How Do I create a Modular Function for use with Event Listeners
OK I'm very new to AS3 and I'm curious as to how to get
modular functions to work in AS3.
for instance if I have this code:
function snowfall(snowflake:MovieClip, movement:Number):void
snowflake.y = movement;
snowfall(snowflake1_mc, 10);
snowfall(snowflake2_mc, 20);
snowfall(snowflake3_mc, 30);
Now on the stage I place 3 instances of a snowflake movie
clip. Each time I call the "snowfall" function I refer to a new
instance of the snowflake movie clip and a different amount of
movement along the y axis.
This is great but what if I want to use a button to control
these snowflake movie clips and I want to maintain that modular
nature? I don't really get how to do this. I created a button with
an instance name of "myButton" and I've tried this code but it is
throwing an error I don't really understand:
myButton.addEventListener(MouseEvent.CLICK,
snowfall(snowflake3_mc, 30));
Can I not pass information to a function using an
EventListener?Hi --
What you want to do on your button is this..
myButton.addEventListener(MouseEvent.CLICK,snowfall)
Then in the function you can check which button called the
function using
properties of the event..
function snowfall(event:MouseEvent) {
trace(event)
I am not sure off the top of my head of the data available in
the "event"
but the trace will show you all the variables you can access.
As far as the amount of movement -- how is this information
set? You can
keep this in a global variable and then read it from inside
the event
handler rather than needing to pass it to the event.

How can we create a common function for 2 or more java card applets?
I have 2 java card applets. They use one common function. But i don't know how to set up it. Anybody knows it, please help me. Please show me step by step to do it. Thank you.
When insert below line of code in the Test_Class_1.java and Test_Class_2, the Project will be failed:
byte aP1 = Test_common_function.GetP1((byte)0x02);
byte aP1 = Test_common_function.GetP1((byte)0x01);
Here is the source code:
Test_Class_2.java
package Test_Class_2;
import Test_common_function.Test_common_function;
import javacard.framework.APDU;
import javacard.framework.Applet;
public class Test_Class_2 extends Applet
public static void install(byte[] bArray, short bOffset, byte bLength)
// GP-compliant JavaCard applet registration
new Test_Class_2().register(bArray, (short) (bOffset + 1),
bArray[bOffset]);
public void process(APDU apdu)
byte aP1 = Test_common_function.GetP1((byte)0x02);
}Test_Class_1.java
package Test_Class_1;
import Test_common_function.Test_common_function;
import javacard.framework.APDU;
import javacard.framework.Applet;
public class Test_Class_1 extends Applet
public static void install(byte[] bArray, short bOffset, byte bLength)
// GP-compliant JavaCard applet registration
new Test_Class_1().register(bArray, (short) (bOffset + 1),
bArray[bOffset]);
public void process(APDU apdu)
byte aP1 = Test_common_function.GetP1((byte)0x02);
}Test_common_function.java
package Test_common_function;
import javacard.framework.APDU;
import javacard.framework.ISO7816;
import javacard.framework.Applet;
import javacard.framework.ISOException;
public class Test_common_function extends Applet
public static void install(byte[] bArray, short bOffset, byte bLength)
// GP-compliant JavaCard applet registration
new Test_common_function().register(bArray,
(short) (bOffset + 1), bArray[bOffset]);
public void process(APDU apdu)
// Good practice: Return 9000 on SELECT
if (selectingApplet())
return;
byte[] buf = apdu.getBuffer();
switch (buf[ISO7816.OFFSET_INS])
case (byte) 0x00:
break;
default:
// good practice: If you don't know the INStruction, say so:
ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
public static byte bP1_Class1 = (byte)0x90;
public static byte bP1_Class2 = (byte)0x90;
public static byte GetP1(byte idclass)
return idclass == (byte)0x01? bP1_Class1:bP1_Class2;
}and here is the trace log (in case of failure)

how do i create an apple id for my 12 yr old?
Welcome to the community.
Unfortunately, you cannot do that. The first hurdle that you are going to face, is that mobile devices, by virtue of being prone to loss, will always require that a password is entered before a purchase of any kind is made.
If your concern about the password, is related to your privacy in regard to your mail, contacts and calendar information rather than their acces to make purchases, then the best solution would be for you to use another Apple ID for iCloud.
Apple have called the whole cloud thing iCloud, there are a number of features under the iCloud umbrella, some of which require their own login. iTunes is one of these, another is what Apple have unfortunately also called iCloud too.
You can use the same Apple ID (account) to login to both iCloud and iTunes, but you don't need to and often users will login to each service using a different ID.
The part that you need to remember is that the services available when you log into iCloud are completely different and unrelated to those when you log in to iTunes. Your iCloud login enables mail, contacts, calendars, find my phone, Back to My Mac, Documents & Data sharing and photostream, it does not affect any of your iTunes services. -

How can I create a Forms9i Runtime for client distribution
Currently we have an application developed in Forms 5.0.6.8.0 our Database has been upgraded to 9i DB. The application is working fine with this combination but we want to upgrade Forms in order to get Oracle Support. We just get the Developer Suite 9i package and we're trying to test our application with this software.
How can I create the client runtime for Forms 9i?
My application will work with Win 95 and 98?
Thanks.Oracle9i Forms is web-only. Forms 6i is the last release of Forms to have client/server and character mode.
You can test Forms from the Builder by installing iDS. To deploy Forms using iAS follow the documentation. It's all there in the deployment guide.
iAS and Forms doco can be found on OTN.

HT204053 how can i create multiple icloud accounts for my family members
how can i create multiple icloud accounts for my family members
Thanks... I appreciate the reply. Since I wrote the previous email, I actually went and changed my apple id (the main id) and the documentation I looked at said iCloud will set mail up automatically(?)... I had it working before.
Also, I tried to manually set up the ID via the Mail Accounts screen(s) and I can't figure out what my server information is... Pop or Imap? What's the outgoing server and the incoming server?
I typically have never had problems setting up mail accounts (in apple mail) with no problem.
Can anyone point me in the right direction?
Thanks in advance! -
Each year for the past 5 years I make a family calendar and send copies to all he family members around the globe. I hate that I have to recreate all the birthdays and special occasions from scratch, and re-drag all the photos onto these dates, in the lower half of the page of each month on the new calendar. How can I create a new calendar for the current year and port all of these photos/comments into the new calendar from last years calendar, to save having to redo all this work!! I am not talking about the upper half page of the photos only...I am referring to the calendar page of each month.
Thanks in advance.
ColinWelcome to the Apple Discussions. Open iWeb so you see your original site in the left hand pane. Use the File->New Site menu option to create a new site. Give it the name you want.
Now select a page in your original site and type Command+D. That will duplicate the page. Drag the duplicate page down to the new site and rename it as needed. Do that for the other pages you need in the original site.

HT5622 How can I create an Apple ID for my child without linking it to a credit card?
How can I create an Apple ID for my child without linking it to a credit card?
Hi Kappy..
that did use to be the case but ios 8 you can create a child's Apple ID which will stay linked to the main Apple ID until they are 13 when they can if you wish take over the Apple ID themselves.
I Have the same question regarding creating an Apple ID for my son but it insists I have to add a credit card to prove I'm an adult.
thing is I don't have another card to add to my Apple ID I have been using the same card for all my family's Apple purchases i just update my details when I get issued a new one.
Any ideas or suggestions greatly accepted.
cheers -
