How can i request an input of data from a deployed web service via a html

Hi all, I am currently having trouble with a web service. I want a client to be able to input a numerical value for a control in a deployed VI.
At present i have one main vi that generates a signal and i've collected waveform data and displayed this data on a a chart. The web service uses a static folder containing html and javascript files. The html file calls the js file which parses the waveform data and returns to html to be stored as a chart_div. I have all the controls and indicators in one VI, connected by terminals using GET method.
I am looking for a way of scripting a request form so that when called by the html file, the client user can input a control and change the values on the waveform graph. I also have an update button that requests updated data.
If anyone could suggest a method of how to accomplish this it would be SO helpful
Thanks, Chris

Hi Chris,
I take it you are using the RESTful API method to GET the data. In that case you shoul be able to perform a http POST from your js code in order to update the controls.
This could be done as form components are updated, or after a submit button is pressed (I'm sure you are familiar with this part).
Please see here for more information: http://zone.ni.com/reference/en-XX/help/371361J-01/lvhowto/build_web_service/
I hope this helps.

Pulling Data from an imported web service into a data grid - Flex 3.0

Hi all,
I have created a web service from Oracle using JDeveloper and imported it into my Fex 3 project, and I am trying to populate a data grid with the data from the web service. I was trying to emulate the example found in my Adobe Flex 3.0 for Dummies book (see http://dougmccune.com/flexfordummies/chapter14/srcview/index.html), and while the code from the book with that data service works fine, I can't get my application to work. My issue is with the part of code mx:DataGrid dataProvider="(service)" - I do not know how to specify what to use for the data source to populate the data grid from my imported web service. Any suggestions or examples would be helpful, as I am a newcomer to Adobe Flex. My code is as follows:
<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"xmlns:webservices="

<mx:Script>

How can i move my game centre data from my old account to another new account??

I want to tranfer my apple id date to another apple id. Because i was using my moms Apple id.. & now i have created my own new apple. So now i want to move my all game centre, icloud data to my new email. Is that possible to move my data from my moms apple id to my apple id.??

iTunes: How to move your music to a new computer:
http://support.apple.com/kb/HT4527?viewlocale=en_US
This is our resident iPhoto guru, Terence Devlin's, advice:
You can move your iPhoto Library to an external disk pr new Mac:
1. Quit iPhoto
2. Copy the iPhoto Library Folder as an entity from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

How can I use notifications to send data from different sources to thesame chart?

Hi,
I am using the "Continuous Measurement and Logging" template project that ships with LV 2013.
It is extremenly helpful for figuring out messaging between the acquire, graph, and log loops. (Thanks NI!)
I've run into a snag however.
I would like to modify it so that my graphing loop receives data notifications from two acquisition sources via notifiers.
I'm having trouble getting data from both sources to display on the same chart.
I've isolated the issue in the attached vi.
Here's what happens:
1. I create data from 2 parallel loops and send the data to a third parallel loop with notifiers.
2. The third loop receives data from only one of the loops because one of the receiving notifiers just times out instead of receiving data.
Can someone suggest how I can fix this?
Thanks.
- Matt

test notification loop.vi ‏42 KB

Here is my modification of your VI. I put notes on the block diagram to explain the changes. It uses a queue for the data transfer to avoid loss of data. It uses a notifier to stop the loops. All local variables and Value property nodes have been eliminated.
The way the loops are stopped will likely leave some data in the queue. No more than one or two iterations of each of the data acquisition loops. If you need to guarantee that all data has been displayed (or saved in a real application), then you need to stop the acquisition loops first and read the queue until you know it is empty and both of the other loops have stopped. Then stop the display loop and release the queue and notifier.

How can I simply restore lost app data from iCloud, without resetting all content. Please someone!!!

I accidentally deleted a timesheet app from my iPhone, I reinstalled the app again but the data did not come back with it. Can someone help me with details how I can restore my lost data for just that app, from iCloud. iCloud is and was set up on my phone and was updated 3 days before this happened. People have suggested I "reset all content and setting" and it will come back. The sounds of deleting all content on my phone worries me. I have no other devices to back up on, so my only back up is in "iCloud"
Is there a simple way I can download and reinstall just the data for the app from iCloud?

Delete all content and settings will wipe your phone. You cannot selectively restore in iTunes or iCloud, it is either all or none. You would have to restore to a backup before you deleted the app to be able to recover the data. However, anything that you did since that time would be lost.

How can I erase all phantom iCal data from my iPhone/Flat Panel Mac?

Tried many ideas and Apple Genius could not even help me. Here is the scoop...
I created an iCloud account then synched my iPhone to my Flat Panel. Suddenly my iPhone showed up to six duplicates of iCal events (often a week or two later than the actual event). My Flat Panel iCal showed no such events. I erased all data and settings from the iPhone, restarted it from scratch (both from a back-up and as a new iPhone). As soon as I synch it to the Flat Panel the multiple events reappear on the iPhone but still not on the Flat Panel. I checked the "replace all calendar info" box in iTunes before synching. I deleted my iCloud account. I tried synching my old 1st gen iPod to teh Flat Panel, and the iCal info there is correct. I erased the iPhone and started over by starting it up/synching with my Macbook Air. The iCal info is now correct on my iPhone. How can I go back to synching on my Flat Panel? Where is the phantom info hiding on the Flat Panel?
Thanks for helping me with this strange problem!
John

Ohnj,
I presume that you are no longer trying to use iCloud for syncing with the "Flat Panel." It will not work since you are using OS X 10.5.8.
Quit iCal, go to your Macintosh HD/Users/yourusername/Library/Calendars folder and remove any/all files with "Cache" as a part of the file name. Then log out/in or restart and see what happens.

How can I use more than one Data Provider in my web Apps

I am trying to use two different data provider in my web apps to run two different queries from the same table ,the data provider A is working correctly but when I attempt to run data provider B ,It display an error page ,here is the error message : Exception Details :javax.servlet.ServletEx ception

Hi,
You can use more than one data provider in your application. However if you have defined a dataprovider for a particular table already, and wish to bind a component, select the component and use its context menu to Bind to Data...

How can I remove all Time Machine data from an external HD, while retaining the other folders/files on the disk?

I recently replaced my old Macbook Pro with a new Macbook Pro Retina.
The original MBP had Time Machine set up on an external HD, and I also had some manually saved/backed up files (stuff that didn't need incremental backups; very old stuff) on the disk as well, in folders. This worked fine and well for the life of the original MBP.
When I set up the MBPr, I did not elect to transfer everything over from a Time Machine disk, as I wanted a Fresh Install; I chose to just re-download/install the apps I needed from the App Store. Much cleaner, more stable. I updated to Yosemite immediately so, it gave me more of a clean install.
The problem is, Time Machine now won't read any Time Machine backups from that disk. Migration assistant can pull data from it, but it's a bit wonky. It was easier to just manually copy over what I needed.
Now, I just want to "reset", and completely remove the old Time Machine data from the external hard drive, since it is completely useless to me now (I can't access it on this computer, and it's taking up space). I want to remove the Time Machine data, as if it were never there, but keep my other folders/files that are on the disk (so, a format is not feasible).
I will then set the disk up as a new, fresh Time Machine disk for the new MBPr.
What is the proper method for removing Time Machine data from an external disk (which doesn't seem to be associated with this machine anyway)? I know a simple rm -rf will cause problems.
Thanks for any help provided.

See the yellow box in #12 of Time Machine - Frequently Asked Questions (or use the link in *User Tips* at the top of this forum).

My Laptop with Synced Firefox crashed and i had to do a fresh install, how can i retrieve all the synced data from the Mozilla Servers

I had set up Firefox sync on my Windows 7 Laptop which crashed and I had to reinstall windows. I used to be able to share content with my Firefox synced Android too. Is there a way i can retrieve the synced data from the Mozilla servers? I tried to set up sync on my new installation on a Mac 10.6 but when i click on Set-up Sync it asks me:
# Set-up new sync account (i already have one)
# I already have a sync account
When i select the second option it tells me to Add a device. I went in the "Sync Options" and tried the replace all data on this computer with my sync data, but nothing happened. When i try to connect from my Android it also asks me to add a device with the 3 boxes with letters in them.
So in both the cases it is asking me to "Add a device" but i cannot connect to my sync account in either case to sync data from there

Please search the forums. This has been covered here extensively.

How can I delete all songs and data from my 80GB ipod classic without opening itunes?

I have an older 80GB ipod classic that works but will not play any songs. I'm trying to delete all songs and data from the hard drive to see if that will fix the problem, however, it will not appear in my itunes. I've tried various ways to help it appear in my itunes but I do not want to delete my itunes because I have another ipod that has all those songs on it.
I was wondering if there was a way to restore my ipod back to the beginning without having to go through itunes. Thanks!

It might, but I wouldn't bet much on it. Either way, give it a shot.
Otherwise, if appears in Windows an external hard disk, try a low level reformat of the device's hard drive. See here for instructions on how to do this.

How can I restore 3rd party app data from my backup in the cloud

First a brief history. I use the iCloud to backup my iPad 2 and hardly ever synch it to itunes on my computer. I got the new iPad and restored the backup of my iPad 2 onto it. All was fine except that an issue I had on my iPad 2's Safari had transferred over to my new iPad. That's is for another discussion. Anyhow I went to the genius bar and they said to just setup my new iPad as a new device and then manually install everything back on it. Stuff like mail, contacts, etc, would be reloaded from the cloud. So I did and I noticed that one of my 3rd party apps, MadPad, had none of my saved data. Does anyone know of a way to restore 3rd party app data from the iCloud? Is there some sort of utility out there that would do this? I don't want to restore it from my previous iPad 2 backup because it will reintroduce the Safari problem back onto my new iPad.
Thanks!

Assuming that you even have a backup with the data in it, you have no choice but to use a backup in order to restore that data. That is the idea behind backing up to iCloud. If that is the only backup that you have - then that is the one that you have to use.
But if the backup is bad - or had corrupt data - then you will end up with the corrupt data again. You cannot selectively restore app data from a backup. you restore all settings and data - or nothing at all.
