    How can I transfer my iTunes library and playlists from one computer to another?

    Copy the iTunes folder (Mac: Home\Music or PC: My Music) to the same location on the new computer. If an iTunes folder already exists on the new computer (it will on a Mac) replace it with one you copied.

  • How do I copy the same app folder layouts from one device to another? We have a several iphones and ipads.

    how do I copy the same app folder layout from one device to another. We have several apple devices.
    It's a challenge when syncing a device for the first time to go through all the apps and apply them back to the same folders as on your other iphone.
    I've seen suggestions of taking pictures of the correct layout, then manually applying it to the new device. Big time waister.
    What's the work around?
    Thank you

    I'm afraid there is no short workaround. One thing that you could do if you were REALLY desperate is reset your device to factory settings and then restore it from your other device's backup, but that is rather risky and you probably don't want to take your chances just for folder layouts. I would just do it manually.

    lots of ways... you could use a thumb drive, you could drag files to the users public folder drop box, you could send it through email, you could use the internet servic called drop box (not to be confused with Apple's user public foldelr drop box).

  • How can I transfer entire contents of Mail mailbox from one Mac to another?

    I've long wondered how to do this:
    I have two Macs - an iMac and a MacBook Pro.
    I have categorized several hundred emails on the MacBook into a separate "mailbox" by itself. Let's just call it "Project XYZ emails" for the sake of discussion.
    I need to transfer ALL of those emails +en masse+, hopefully still categorized together into a separate "Project XYZ emails" mailbox file, from the MacBook to the iMac. How is this done?
    In the old days, when I used to use Eudora, this was quite simple -- one could physically locate the separate desired "mailbox" file in the Finder and just copy it from one hard drive to the other, and then place the mailbox into the appropriate place of Eudora's file structure on the second computer. Relaunch Eudora and voila, the new mailbox is there for viewing, etc.
    But in Mail, I can't find any tangible "file" on my hard drive that represents a "mailbox" in the Mail program. And that includes control-clicking the application file itself and choosing "Show Package Contents." When I do that, I can see, after burrowing into the folders, a single large file called "Mail" which I think contains ALL mailboxes lumped together. But I can't see a way to separate them for individual manipulation.
    Any suggestions or ideas on how to copy entire mailboxes in Mail from one Mac to another?

    Thanks! Seems to have worked.
    Once I imported tham, I had to fiddle around renaming mailboxes and "moving" the emails to the desired locations, but that only took a minute. So overall, seems like that's the solution! I only wish that the steps to do this were made clearer by Apple in the Mail "help" menu -- where I couldn't find any mention of how to do this.
    A happy ending, in any event.
    In case anyone reads this in the future, let me add in the missing steps, to make it perfectly clear:
    In Mail, choose 'archive mailbox' from the mailbox menu.
    +Copy the newly created archived mailbox file, which will probably be a file with the suffix ".mbox," from the original machine to the second machine.+
    On the second machine: In Mail choose 'import mailbox' from the file menu.
    +The emails will now appear in a new mailbox in Mail listed under the name "imported" or "import." If desired, either rename the mailbox, or create a new mailbox with the correct name, and "move" all the emails into it.+
    Done!

  • HOW TO GET THE SELECTED VALUE IN A ROW FROM ONE VIEW TO ANOTHER VIEW?

    hi all,
    I  have a small issue.
    i have created two views.In the table of the first view i'm selecting a row and pressing the button it will move to next view.
    i am adding some fields manually in the table of the second view and pressing the save button.Here all the values should get updated corresponding to the field which i have selected in the first view.
    I want to know how to get the particular field in the selected row from one view to another view.
    Kindly help me.

    Hi,
            Any data sharing accross views can be achiveved by defining CONTEXT data in COMPONENT CONTROLLER and mapping it to the CONTEXT of all the views. Follow the below steps.
    1. Define a CONTEXT NODE in component controller
    2. Define same CONTEXT NODE in all the views where this has to be accessed & changed.
    3. Go to CONTEXT NODE of each view, right click on the node and choose DEFINE MAPPING.
    This is how you map CONTEXT NODE and same can be accessed/changed from any VIEW or even from COMPONENT CONTROLLER. Any change happens at one VIEW will be automatically available in others.
    Check the below link for more info regarding same.

  • URGENT: How to selectively migrate composite instances and task data from one env to another

    Gurus,
    We've come across a situation whereby we need to migrate instance data (including Human Task related) of some specific composites from one environment to another.
    (Environment is equivalent here to a different domain installation on different physical server.)
    Is this possible in some standard way like using Oracle import-export utility or script?
    If not, how can this be achieved?
    Thanks in advance for any help you can provide on this.
    With regards-

    Hi,
    If your SharePoint environment supports InfoPath Forms, then you can customize the form and add rules to make the list items as read only when user A submits the form.
    you can then write a form load event to check the logged in user using username() function. This logic can be implemented in variety of ways, like setting a flag when User A submits the form, or storing user A username in a form variable etc., else comparing
    User A and User B values within form Load event.
    Another way of doing this is using Views or grouping all of the User A fields within a section etc.,
    The above would take care of Form logic, and for the workflow, you can use SharePoint designer to create a custom workflow, where it will run on onItemCreate and onItemChange events.
    The logic for workflow would be if the form Submitted for the first time, the workflow will start and send an email to User B, and when User B submits the Data then onItemChange change event will start the workflow to send an email to approver to approve
    the data.

  • How do I move all the apps and podcasts from one mac to another mac?

    What is the best way to move all the apps and iTunes content (songs, podcasts, etc) from one Mac to another Mac?  I am switching to a newer computer.  I connect (with cables) an iPhone 4 and an iPad 2 to the old computer for syncing.

    Take a look at this.
    iTunes: How to move your music to a new computer
    When I recently got a new MacBook, I set it up with Times Machine using a backup of the old computer. It could not have been easier. If you use Time Machine - that will copy the contents of the old Mac to the new Mac - iTunes library included. You will have to authorize the new Mac in iTunes - Store>Authorize this computer.
    There are ways of copying the purchased contents from the iPad to the new iTunes library as well if you need to do that. But as long as you have the old Mac - copying the library and putting it on the new Mac makes the most sense.

  • How to reference a Textbox or a Grid object from one tile to another tile

    Hi,
    then I would implement sth like the following:
    dim myBO as businessobject
    dim i as integer, sValue as string
    for i = aMyAnchor.bcol.count to 1 step -1
      sValue = aMyAnchor.bcol.GetAttribute(i, "myProperty")
      if sValue = "" then
        aMyAnchor.bcol.item(i).delete
      end if
    next
    Please note that the deletion needs to be done bottom-up because of a refresh of the
    indexing after deleting of objects in the collection.
    The refresh of the grid is done automatically because of the data binding.

  • How can I swap or cut & paste a head from one photo into another for a holiday photo using aperture or photoshop?

    I've got an almost perfect family photo that I need to swap one face in as my son was not looking at the camera and I can't redo the shoot.  Anyone know how to take a headshot from one pic and swap it into another using Aperture or Photoshop?  Thanks!

    select the head with one of Photoshop's selection tools
    When doing this, I find it quite helpful to create an intermediate image with a transparent background that contains only the head to be pasted into the second image. First I paste the head onto this transparent background, scale it, rotate it or skew it to make it fit into the other image, adjust the lighting, then select it.
    To be able to paste the head seemlessly into the second image (and without aliasing effects), I make the border of the selection soft (⌥⌘D); my Photoshop has a german interface, so I am not sure about the english localization, this command must be something like "selection -> modify selection -> soft border".
    I would not bother to get the lighting and color excactly right in Photoshop, that is  far easier with the "dodge" and "burn" brushes and color adjustments in Aperture.
    To do this completely in Aperture, you would have first to combine both images into one (for example by creating a book page), then use the retouche->clone tool to stamp the head from one image to the other. I use this occasionally to stamp a face into a flower bud or for  similar effects. However, for this to work you need a plain background and nearly circular shapes to be pasted.

  • How to move a DB in a recovering state from one server to another?

    I have a server with many DBs in a "recovering" state (log shipping secondary). There is a hardware failure and the server needs to be recreated.
    How do I keep the DBs so that I'll be able to attach them to the new server?
    I tried to backup the DBs but I get this message:

    Database 'DBName' cannot be opened. It is in the middle of a restore.
    I can't bring fresh backups from the main site as the sites are far from each other and moving the backups will be too expensive.

    You can run recovery on current log shipping secondary database to bring it online as Suggested by Neha. Now take differential backup from primary and restore it on secondary to recreate logshipping.Diff backup would be less in size and would take less time
    to transfer.
    Since you had hardware failure I guess it would be good option to recreate Logshipping what was extent of hardware failure ? .Because since hardware was corrupt any files residing on it might as well be damaged.Take a full backup of primary database and
    move it to secondary and restore it with standby.Before that please remove database in recovery mode either by dropping it or by first running recovery and then

  • How can I transfer/copy my entire iPhoto library from one iMac to another iMac whilst keeping all the folders and subfolders intact?

    We recently purchased a new iMac for our office (8 GB memory, 2.7 processor, version 10.9.2) and we need to copy the iPhoto library from our other iMac (version 10.9.4) onto the new one. The photos are essential for our work and there are around 53,000 of them all organised into folders and subfolders and then the photos are manually ordered within the albums.
    We have tried connecting the computers but when we tried to access the iPhoto library on the new iMac it says that iPhoto is locked and we do not have permission to view it. We updated iPhoto on the old iMac as we thought that might be the problem but the message still appears. We've been advised to use an external hard drive but we're worried that will corrupt the organisation of the library. We have also been told not to do it over AirDrop / the Server because of the sheer quantity of photos.
    Any advice on how to safely do this would be much appreciated.

    No idea exactly what you did
    if you followed the instructions
    Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
    Then launch iPhoto. That's it.
    This moves photos, events, albums, books, keywords, slideshows and everything else.
    then you have exactly the same thin on your new system that you had on the old
    If you do something differently - like import the library instead of simply opening it - then it will not work
    did you dimply drag the iPhoto library from the pictures folder of the old machine to the pictures folder of the new machine and then launch iPhoto on the new machine?
    and to help it is important to use word correctly since that is the only communications method we have - in iPhoto folders do not contain photos - you view photos in events and you can organize them using albums (which view photos) and folders (which hold either albums or other folders - folders never have photos in them) so your description of the problem is not at all clear since it uses folders incorretly

  • HT1178 How can I use Time Capsule to move music from one computer to another?

    I want to move all the music I have on my old laptop (macbook) to my new macbook pro. How can I do this? Easy, simple, steps would be greatly appreciated!

    Are you moving the itunes library?? That is entirely different to moving just music.
    Apple have specific instructions for moving libraries..
    And there is no need to use the TC.. other than as a switch and router.. share the folder in one Mac to copy to.
