How do I allow an alarm to be set based on a comparison but then NOT aloow the alarm to clear until a button is pressed?

I have a program that compares DAQ values to a threshold value. If the value surpasses the threshold, an led blinks. The problem is, if the value then goes back below threshold the blinking will stop, as a result of the comparison being False. What I want is to allow the alarm to begin the blinking but not allow it to stop until I press another button, essentially clearing the alarms. I am just flabbergasted at how to accomplish this. Any ideas?

Attached is an example of what I described.
If you turn the dial past 5 the LED will turn ON.
If you turn the dial down (even to 0) the LED will remain ON until you reset the alarm (RESET button).
If you press RESET while the alarm is active, it will only turn OFF the LED when the value is below 5.
You can stop the vi by pressing STOP.
Hope this is what you were looking for..
enjoy..

How do I find a previously passcode to link a wireless keyboard (Model A101urs6) to a Mac Power Book G4 running 10.5.8. The keyboard was linked at one point in the past, but then not used. When I am trying to hook it up now, it requires the passcode.

You need to ask Apple to reset your security questions; ways of contacting them include phoning AppleCare and asking for the Account Security team, clicking here and picking a method for your country, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.

I have playlists on my original iPod but are not in the library. How can I move them from the iPod to the library?

She can choose to either enable the setting on her iPod to Manually manage music and videos. With setting enabled she can sync content to her iPod from multiple computers without it affecting whats already stored her iPod. For more information on syncing content to an iPod manually see this article.

However, I would recommend copying whats on her iPod to her iTunes library first. There are several ways to accomplish this. See this older post from another forum member Zevoneer discussing the different ways to do it.

Some albums I put on my Mac to later sync with a Touch appears as seperate tracks and not a single album. How do I get them back together again other than a playlist. I do not want the tracks showing up as albums on the Touch?

Are your tracks pat of a collection? Different artists, but still one album? Then mark them a s acollection or set the album artist. See this guide on how to group separate tracks into albums:

My wife's iTunes used ID will not work. Tried resetting the password, but email was not received. Tried using personal questions method, but would not accept the correct date of birth, so could not go any further. Has her iTunes ID been hacked? How can I fix this?

Thanks for that advice @randers4.
I linked through and submitted my info as a "topic not covered" in the iCloud section. After entering the serial number of my MBP it turns out I wasn't eligible for technical support (though I don't think this is hardware related support) and the final suggestion was to take my computer into an Apple store. I called my local Apple reseller and asked for assistance. The customer service rep was very nice but unable to help, so suggested I call Apple Support on 1300 321 456. I did so and, again, spoke to two very polite and helpful customer service people (I was transferred to security services). I didn't have to be on hold to speak to either rep for more than a few seconds! After trying a few different things, he worked out what was happening...
So, to cut a long story short, to solve the problem in my OP, all I had to do was log out of iCloud in my System Preferences and log back in using my current Apple ID. [Edited to add that I had to sign out of everything I was currently signed in to with my Apple ID before logging out and in again.]
Problem solved!

You don't. Change all your passwords, tell you provider, tell the police, tell your insurance company.

I want to give my old iPhone 4 to my grandson to use like an iPod Touch. Wifi only. How do I deactivate my info..so he can buy his own apps. and not have the cloud pushing all of my data to the old phone?

Just turning off Cloud will not prevent him from turning it back on.
Rignt now, if he uses the App store, iTunes thinks it's talking to me.

First, turn off iMessage, FaceTime & delete the iCloud account, while your sim is still in the phone. Then: Settings>General>Reset>Erase All Content & Settings. Give it to your grandson & he gat then set it up as he wants.
Important your turn iMessage & FaceTime off to disassociate the phone from your Apple ID. Apple "claims" to have fixed this with iOS 6.0, but until I can absolutely confirm such, I still recommend you turn all of that stuff off first.

My playlists show how many titles are in the playlist but does not show the list of titles

my playlists show how many titles are in the playlist but does not show the list of titles. Is there a setting that I hit by mistake to hide the content?

Perhaps you have made one column extra wide and the window isn't currently showing the Name column. Try resizing columns, turning off those that you don't need, or scrolling sideways.

Hi,
May the below code is useful for you, but I dont know how to sort.
Edit the tag as per your job request.
alert(app.activeDocument.xmlElements[0].contents)
//Second alert
var xe = app.activeDocument.xmlElements[0].evaluateXPathExpression("//marginalnote");
alert(xe.length)
for(i=0; i<xe.length; i++)
alert(xe[i].texts[0].contents)

The ipad music app does not allow me to play certain tracks that i have synced via my itunes. The tracks are clearly visibly in the music app but when tap on them to play they wont play. help and advice will be much appreciated

The ipad music app does not allow me to play certain tracks that i have synced via my itunes. The tracks are clearly visibly in the music app but when tap on them to play they wont play. what do i do?

Agree about the disaster part. I haven't found a fix within iTunes.
I gave up and switched to downcast 2 days ago. Even though it was a hassle to re-subscribe to all my podcasts, im so much happier.
To make switching easier, I found that in iTunes you can "get info" on the podcast and copy the RSS address to the clipboard. Put all of these in a message note. When iCloud syncs the note to your phone, you can copy and paste the urls into downcast one at a time to subscribe.
Downcast has crashed on me occassionally when I'm subscribing to feeds, but so far it has recovered gracefully each time and no data was lost.
