  • I am pulling my hair out! I am using adobe indesign and just want to make a text box 'autofit text' as I change fonts a lot and want the font to automatically re-size as I change it. help help help please - I have latest version of indesign - thanks

    I am pulling my hair out! I am using adobe indesign and just want to make a text box 'autofit text' as I change fonts a lot and want the font to automatically re-size as I change it.
    Is it not possible to create a text box, fill it with dynamic (data driven) text, but make the font size either scale up or down automatically, so that the entire text box is filled? This is a feature in PrintShop Mail Pro called COPY FIT. but no such feature in Indesign??
    help help help please - I have latest version of indesign - thanks, DJ

    lol... it seems to work, but I have another huge problem!
    Apparently .CSV files cannot contain page breaks in the data! The data I am trying to merge is a 'letter', with paragraphs, line breaks, etc.,
    But, after data merging, it ignores page breaks and only merges the first paragraph of each letter. (sigh)
    Solution? Hopefully, an EASY solution. lol as we have thousands of records.
    Is there a third party indesign plugin that will allow .xml, or .xls data merge import??
    Thx,
    DJ

    Help help help.
    I just deleted a note from the Notes App form my ipad3. I don't use iCloud. The only place this note was is my iPod and iPad. Is there any possible way to recover this note?????
    Thanks in advance

    Thank you sberman, yes the first thing I did was check my iPod. Instant synching works great between the iPad and iPod, so it was deleted there as well. On both devices I have my Notes account to the same account.
    I ashamedly have not synched to iTunes for ages. After I calmed down I realized that most of the info on that deleted Note I had copied and pasted from an excel file in November. I'm in the process of doing that again, and am only out the recent info.

  • HELP HELP HELP!  Hidden midi track or something!

    Hey okay, so here's my STUPID dilemma.  I'm so stuck.
    Im in the process of working on Putting all 6 of my songs into one big project file, this way all the settings, tracks, eq's everything are perfectly the same from song to song so my mastering process can be more universal. 
    ANYWAY.
    Upon dragging and dropping one of the songs into my main project.  (from one open project to another open project)
    Apparently the drum track  (which is one midi track)  from the third song... is now like EMBEDDED, hidden about midway through song 2.
    So when I'm playing the whole thing, it goes nicely through song 1, nicely through about half of song2... then the drum track from song 3 pops in randomly ONTOP OF EVERYTHING ELSE. 
    the thing is... theres NO SIGN OF IT ANYWHERE.  I cannot find the track.  Its not on a hidden track.  Its just like secretly embedded into the project.  I've even DELETED the midi thats SUPPOSED to be playing at that time.  And it still just playyyyyyyyyys and plays this stupid track.
    Does anyone possibly have any ideas?
    I cant find it in the bin, because it doesnt store MIDI tracks there.  is there a bin for all the midi info?  That could work if it appears.
    Otherwise is there a secret way to like, Show any hidden info or anything? 
    IM SOOOOOOOOOOOOOOOOOOOOOO FRUSTRATED!
    HELP HELP HELP!                  

    Hi
    It might be worth taking a look at the Mixer layer in the Environment to see if you can track down which Instrument Channel is playing?<edit> Could be an Ultrabeat with the Sequencer on?

  • Help help help me pleas my i pod will not turn on

    HELP HELP HELP HELP me  please my i pod will not turn on...

    Did you try plugging it in? With the information you have provided, the only course of action I can suggest is plugging it into a power source, then holding the lock and home button simultaneously for about 10-15 seconds, until you see the Apple logo. I am no pro, but that's solved similar problems for me in the past.

    /var is a hidden folder, so you mustn't remove the folder.
    The only solution is to reinstall OS X. If you have OS X Lion or Mountain Lion, use OS X Recovery > http://support.apple.com/kb/HT4718
    Hold Command and R keys while your MacBook is starting and reinstall OS X. You won't lose anything. If you have a backup, you can restore it after starting in OS X Recovery instead of reinstalling Mac OS X, so you will save a lot of time

  • MACBOOK WON'T START HELP HELP OMG HELP!!/1/1kghl

    SO! I recently bought a white MacBook and an iPod Nano (gen1 because I wanted them to match). Since then I have had to send in the first iPod, get a second one, and have the exact same problem--neither the MacBook nor the iPod seem to realise at all when they are plugged in. No charging, no syncing with iTunes. Nothing.
    So the customer service bloke told me that I should update OS X. Alright, I toddle on off to Barnes and Noble to take advantage of the Wifi, as I live in the middle of no where and am still on dial-up. Update, update, restart time. I'm supposed to hold down the power button while it restarts.
    Familiar with having to hold down keys while things happen, as I've used Windows all my life, I do. Except, apparently my button-pressing skills are TOO well-honed, because it begins loading and then turns off! Oh no! I may have held that button down a bit too long...
    Easily solved, right? Just boot it up again.
    Except it won't turn on! Well the little flashy LED light goes all flashy, and the thing sort of growls at me like it's in pain. The screen stays black, nothing else happens. I hold down a lot of buttons and still nothing happens. I've been trying turning it on while holding down different buttons, but still nothing. Honestly, I don't handle panic very well.
    So, basically. I am totally freaking out. HELP HELP HELP PLEASE HELP.
    Please pretty please?
    X-POSTED FROM INSTALLATION & WHATNOT FORUMS BECAUSE I AM TOTALLY FRANTIC. Sorry!

    Welcome to Apple Discussions!
    First off, please don't crosspost your question unless instructed to, as it only wastes bandwidth and makes it harder to track who is asking what question.
    Second, sleep it off a night, with your machine unplugged and no battery inserted to get rid of your franticness. It never really pays to be frantic in front of a computer because you don't know what you are doing, and you could be your own worst enemy.
    When you are ready, depress the power button only for 2 seconds and let go.
    If that doesn't work reset the power manager:

    Also try zapping the PRAM if that doesn't work:

    If neither works, are you getting anything on the screen?

    No I didn't even read through your post, to long.
    You said that "No matter what program I try to install, as soon as the installer opens it crashes". Were you talking about the install for this/these 3D programs or ANY program? As it is worded it sounded like ANY program. That tells me there is a problem with your Mac, software or hardware.
    Now you say others install programs, which is it. Programs other then the 3D ones install or no programs install?
    Could simply be your Mac is to old to run these programs and the installer knows that. You never said what model or year Mac it is.

    As Johnathan has written yes apps for iPhone will work in the iPad, however there is a '+' mark on the icon you touch or click for download which indicates both iPhone AND iPad apps. Those apps will display perfectly for the iPad.

    If you have a credit card on file on top of your gift card then it is asking you to confirm the security code for the card, which for a Visa or MasterCard is 3 digits located on the back, or AMEX has 4 digits on the front.  This happens just to ensure that you are the account holder, and would happen from time to time whether it was a free or paid app, even if you have a credit through your gift card.  This doesn't mean that your credit card will be charged.
