How to avoid blinking / moving of rows in a data grid when you restore the scroll positions
By Default when an update is made on a data grid, it scrolls to top row. To avoid this when we save the vertical and horizontal scroll
positions and restore the scroll positions after the update, it causes a blink in the grid (or moving / jumping) of rows. Is there a way to
avoid this jumping of rows?
In JavaScript this can be achieved by overriding the scrollToTop / OnLoad methods of datagrid to directly scroll to current scroll
positions instead of top row. Is there a way to achieve similar feature in flex / actionscript?
I am calling validateNow().. Also, using verticalScrollPosition to restore the scroller as in the link that you posted.. Reposition is working fine, But the bug filed is regarding BLINKING / JUMPING when this happens (i.e. this blinking is caused because after datagrid edit, during reload the scroller tries to move to the top by default, then it repositions itself to current edited row as the verticalScrollPosition property is overridden ).. I have to get rid of this blinking.
In Javascript it is dealt by overriding OnLoad method of datagrid to directly scroll to current scroll position instead of top row during reload so that there is no blinking.

Is there a way to achieve similar feature in flex?
I am not sure what flex datagrid method to override.. Theres no method like load? What is the datagrid method that is called by default during reload (after datagrid edit) that causes the scroller to go to top?

i'm trying to read several interactive pdf on my ipad, but when i touch the screen it ppeares a top bar with "ok" that if i touch it closes the pdf, an upload button, & the thumbnails of the pages on the righ side of the screen appears too. Does anybody know how to avoid it? Thank's
Are you saying that all pages appear blank when you open the particular PDF document (AINF....pdf) in Adobe Reader for iOS? It may be due to a bug in Adobe Reader for iOS.
You mentioned "links"...There are three different actions that the desktop version of Adobe Reader supports for links.
Go to a page view (within the same document)
Open a web page
Open a file
Adobe Reader mobile products (for iOS, Android, Windows Phone) support the first two but does not support opening a PDF file or any other types of files.
Additionally, hyperlinks are not visible in Adobe Reader mobile products. (It used to show hyperlinks in light blue highlight. But due to customer complaints, hyperlink highlighting has been disabled.)
Please let us know if you can share your PDF document with us (Adobe). We can take a look at it and diagnose the cause of the problem. Thank you. -
In iphoto how to get the gold you delete a photo warning message when you check the box not ask
in iphoto how to get the gold you delete a photo warning message when you check the box not ask
Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
(On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
(Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
What's the plist file?
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101. -
I deleted the picture in iphoto, then emptied my iphoto trash, but the picture is still showing on my computer when i go into my trash under “all images” How do you delete pictures even when you empty the trash and they stay in the computer?
Wtih iPhoto 9 when the iPhoto Trash is emptied the files get moved to the Trash bin in the Dock as a second chance to change your mind. Look in the Dock's Trash bin.

How do you delete songs that you purchased through iTunes but don't show up when you connect the iphone to iTunes? They don't show up in the music section when you click on "On this phone". Side Note: I have my phone setup to manually manage music. Please help.
Hi, Mrs.Frankie57.
Thank you for visiting Apple Support Communities.
If you want to delete a song from your iOS device on iOS 7, tap Songs, swipe the song from right to left, then tap Delete. The song is deleted from iPhone, but not from your iTunes library on your Mac or PC, or from iCloud.

Hello. I am a new Mac user. A couple days ago, I purchased a brand-new MacBook Pro, and have become very fond of it. So fond of it, I have become quite obsessed and protective of it as if it is my own child. Lol. Anyways, the only thing I am trying to figure out is how do I make a password come up as soon as I turn on my computer? I already have it set where whenever it goes asleep it asks for the password, but how when I turn the Mac on?
Open the "System Preferences" app and click on "Accounts".
Click "Login Options" at the bottom of the list of users.
If the options in the dialog are greyed out, click the padlock and enter your password to unlock them.
At the top of the dialog you should see an "Automatic login" option: change this to "off".
You should now get the login window when you start the computer. -
I have an Retina display MacBook Pro with HMDI out port. I also have an HDMI to Component cable with Audio Plugs. How can I get HDMI out to work with this cable when plugged into the MacBook Pro and connected to the TVs Component and Audio in ports.
Will not work. To my knowledge, dual converting like that isn't supported. The Mac must detect the connected video output device and that sort of info cannot be done across an analog component uni-directional connection.

In Contacts version 8, how can I print ALL information in each individual card? When I select the print command the only thing printed is the name and address. I need phone number(s) and all other information in the cards. We enter various pieces of data, other than the standard name address & phone numbers and we print all information on each card so it fits in a 5x7 inch loose binder. We have used InTouch software for many years and it has served us extremely welll, however, the publisher (The Prairie Group) has not, and apparently has no plans to update their software to be compatible with any Mac OSX OS beyond 10.6. Any help will be appreciated!
You can select what you want included in a list format. In the Print command from Contacts, click the Show Details button. Then in the Style pulldown menu select "Lists" and there you'll be able to select what you want included. You can also select what you wish included if you select the Pocket Address Book style.
If neither of those options will work for you, then you will need to look to third-party software. Here's one possibility that seems to get good reviews:
https://www.macupdate.com/app/mac/15485/labels-&-addresses
I haven't done more than try it to make sure that it works with OS X 10.9's Contacts, which it does, but you can download their demo and try it yourself.

How can I convert an Excel (2008) document to Numbers. When I drag the Excel document onto the Numbers icon I get, "Import error. The file format is invalid.
That extension identifies the most current Excel file format, a format that can be opened by Numbers '09 (and by Numbers '08).
A check with Numbers '09 shows it capable of opening .xlsx files when right-clicked (and Numbers chose as the application to open, when double-clicked (if Numbers has been set as the default application to open this type of file, or when dragged to the Numbers icon in the dock.
I see two possibilities for Numbers inability to open it and the message you receive:
1. The file is not actually an Excel file, and the sender has added the .xlsx extension to the filename manually.
2. The file is an Excel file, but has somehow been corrupted.
Have you tried opening the file with a different application? The open source Office suites, OpenOffice.org, LibreOffice and NeoOffice can also open .xlsx files. If they're unable to open this one, that would point toward the file itself being faulty. You can download these applications from their rspective websites, linked in the names above. All request a donation to support future development, but only Neo requires one to have been made recently, and that only for the current release (which won't be necessary to open .xlsx files).

How can you get your iPod touch open when you forgot the password and its disabled and not connected to the Internet Connection and you don't want to reset it.
Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.
