How can we get a value in a drop down box without refreshing the page

In my application i am having 14 drop down boxes. On selcting a particular value in a drop down box i am doing its corresponding functionality. I would like to get these values without refreshing the page each and every time i select a text box, Is it possible to get these values without refreshing the page each and every time.

There is a new hype going on called AJAX. It is either that, or dumping a lot of information in javascript arrays and reading the information from there when you make selections. I would choose AJAX.

AppleScript how to use "get" for field information and drop-down boxes?

Hi all,
First post.
Looking to use the "get" function or similar for getting information in a list or from a drop-down box or a field.
Example, you open keychain, open the info. for a cert and want to read the currently selected trust setting for "When using this certificate" drop-down.
Or, you want to check the Common Name field under details.
How would I return these specific values?
Thank you,
-b

The exact question being asked here: http://forum.soft32.com/mac/select-table-row-ftopict101735.html
But, that doesn't work with the latest AppleScript.

How can I get rid of baseline drift in an ecg without having the dfdt or advanced signal processing toolkits?

Hello,
I am recieving a lot of baseline drift in my ECG signal and was wondering how I can get rid of it? I saw examples at NI .com but they used the digital filter design toolkit and the advanced sgnal processing tollkit. I have neither one of these and since I am a student and this is my senior project I have no means to get these toolkits. I tried using a high pass filter but this did not work.\

Ray,
When you say that something did not work, you are not giving much information for us to use to try to help you. Did the filter not work or did it not remove the drift?
How big is the drift, compared to the desired signal? How fast does it drift? How long are your sample sets? What are you doing with the ECG data? Looking at heart rate or analyzing a single-beat waveform for morphological changes? I think you can see that different end goals might require different approaches to baseline compensation.
If the drift is always fairly slow, you might be able to take small segments and subtract the mean of each segment. This may result in some offset or shift at the segment boundaries, but it is very simple and can easily be implemented without requiring a special toolkit.
Another approach is to low pass filter the ECG signal to extract an estimate of the baseline which can then be subtracted. Remember that all filters have a transient response and many will have a phase shift between the input and output.

How can I get App Tabs to automatically load a fresh version of the page every time I click on them?

I like the app tab feature and am using it for sites that I visit frequently, for example, weather sites. The problem I have is that when I click on say http://www.metoffice.gov.uk/weather/uk/ta/arbroath_forecast_weather.html I get the site as it was the last time I used it. Today this meant I got a weather forecast starting from 2 days ago, not from today.
I can get round this if I remember to "Reload" every time but I'm guessing that is not the way app tabs were intended to work.

One of these two add-ons should do that:

How can I get an flv video to stop playing when I exit the page it's on?

The audio continues to play no matter where I navigate on the site.
Thanks

You want to stop the audio from playing and also downloading more video/audio if it is still downloading when you go to a new keyframe where the video display/component or mp3 player is removed from the stage because it's keyframe ended or do not exist anymore but you still hear the audio.
Add an event listener to your video playback component that calls a function when the flash player tries to remove the video plaer from the stage that stops the netstream or at least stops/pauses the video playback.
[link removed]
//sample NetConnection and NetStream classes when the video player is removed from the stage tell the NetStream to stop playing or downloading the content with .close();
var connection:NetConnection = new NetConnection();
connection.connect(null);
var stream:NetStream = new NetStream(connection);
addEventListener(Event.REMOVED_FROM_STAGE, videoRemovedFromStage);
function videoRemovedFromStage(e:Event){
stream.close();

Same error message keeps popping up every hour or two, and I can't get rid of it, also appears whenever I manually refresh the page.

I'm running a script for a game through grease monkey, and I require the script to run 24/7 without me needing to be there 24/7 to press "continue" when this error message comes up "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." I've looked though all the options and can't find any way to prevent this from happening. I've uninstalled and reinstalled grease monkey, the script, and firefox itself, and nothing makes it go away. I have friends using the exact same scripts with the same version of firefox and they never get the error message. Is there something I can do to get rid of this inconvenience, as it literally does not help at all, I see no purpose in even displaying the message, obviously if I didn't want my browser to refresh automatically, I wouldn't be using the script.

I think I've got it fixed....I "reset" my mail program, I deleted my mailbox then re-created it and I'm all set for now.

You could set the table's data model to be the same:
output2.setModel( output1.getModel() );

You can use the D2KWUTIL.pll library to read/write to the registry. You have to install the forms examples to get the library.
The library d2kwut32.dll must also be installed at the clients.

How can I get an album to play in order on Itunes? The songs keep skipping all around to other albums that I did not want to listen to at that time?

How can I get an album to play in order on Itunes? The songs keep skipping all around to other albums that I did not want to listen to at that time?

It sounds like you might have the shuffle button at the bottom left of the iTunes (the button with the squiggly lines).
If that's not the case, then maybe you just need to sort your library by album by clicking the album tab at the top.
Is your music in a playlist, or are you trying to play it from the entire library?

how can I get a date picker or wheel to show up in the form to make filling in a form with a lot of dates more easy?

There is no built-in date picker available for forms created in Acrobat. There are some third-party solutions involving JavaScript (either a large collection of fields or a custom dialog) though. Also, text fields with date formatting will use a wheel type date picker on Android/iOS devices with Adobe Reader.

I have a DVD Acrobat Pro 9. I upgraded laptops and trying to install but the DVD is not readable. How can I get a new DVD or Download Acrobat Pro 1. The product is registered and I have the serial number. PS: Contacting Adobe on this issue is impossible... direct support stinks.

Download AA 9 Pro from http://helpx.adobe.com/acrobat/kb/acrobat-downloads.html. Make a new backup for your archive. You might also take the DVD to your library to see if it is a drive problem. You might also carefully clean the DVD with water and soap (do not use anything that would scratch the surface or you have destroyed it for sure) and see if that solves the problem. This is particularly an issue if you have finger prints or other crud on the DVD. However, it could also be a bad drive as I mentioned. Hopefully the download solves your problem in any case (I would backup the download to CD and/or backup HD).

Welcome to the Apple Support Communities
See > http://support.apple.com/kb/HT5404 AirPlay Mirroring is compatible with Mid 2011 and newer MacBooks Air, and OS X Mountain Lion.
As you have Mac OS X Snow Leopard, you haven't got a compatible MacBook Air, so you can't use AirPlay Mirroring. However, you can use a third-party app as AirParrot to mirror the MacBook onto your Apple TV > http://www.airparrot.com

How can i get a iphone 3G out of recovery mode without restoring it

Need Help, How can I get a iPhone 3G out of recovery mode without restoring it. it has never been backed up so restoring it will loose all contacts etc.

You can't get it out of recovery mode without restoring it.
If it's in recovery mode, your data's almost certainly gone anyway.

If you connect your iPhone to a computer running Linux (Ubuntu version in my case) it will become recognized as a normal USB memory pen-drive.
From there, you can use many methods to recover your lost deleted files.
TestDrive allows you to search the drive (iPhone memo) and gives you the possibility to recover deleted files. I'm not an expert, nor did it with iDevice by myself. But it worked for me with Symbian phone (Nokia)...

Hi,
You may try checking the help page for ldap configuration :
https://<Appliance_IP>:215/wiki/index.php/Configuration:Services:LDAP
ZFS Storage supports LDAP, NIS, AD as directory service.
Hope Open Directory is also based on LDAP and may work in similar fashion.
