I need to update specific records(of variable lengths) in a file. I can get the correct record but when I update it(add or change info), it overwrites part of the record following it. I am using labview 6.0. I need to be able to insert information into the middle of a file without disturbing the data before and after
It's hard to give more specifics without more detail, but in general you're going to need to read in the entire file, split it into three pieces (everything before the record of interest, the record itself, and everything after the record of interest), modify the record, reassemble the three pieces in proper order, and write the whole thing back to the file.Of course if the file is very large you might not want to actually implement it this way, but conceptually at least, this is what you are looking at.If this file some sort of proprietary format?Mike...PS: this type of issue is why I really like databases...

I bought a new laptop and can access my itunes library but when i try to add purchased playlist songs to my ipod message appears asking if I'm ok with erasing all other songs on the ipod. How do I add purchased playlist to ipod without erasing existing ipod playlists?

wow ... I get a headache just trying to read what you just said. I went and read how to migrate my library and found that you can only migrate purchased media.
No, you can easily migrate your entire library from one working compter to another.
If you fail to backup or migrate your library and find yourself with nothing but a new empty computer and a device full of content iTunes is designed to only recover the iTunes purchased content, however third party tools can help recover everything if needed.

I went to icoke.ca and entered my pin to get a free song, but when I went to itunes to redeem it, its says that my code has already been used. Help!
It wont even accept my icoke pins! when I enter them (and there are two on the inside of the cap) it says its an invalid pin.. Other places online says this offer expired March 31, but on the bottle cap it says 12/31/2011 so I dont understand,. Why do you offer a free itune when one cant access it?

Is there any way I can get the new IPhone 4s and not use Verizon, Sprint, or AT
I use Straight Talk Wireless and I really want the IPhone 4s and I can't switch companies.
Ditch Straight Talk and go to Sprint. You pay $200 for the phone and $70/month. That's $25 more than Straight Talk but you get much better service. 2 years of Straight Talk and a $650 iPhone save you only about $2-300 than you would by going with Sprint if it was possible to use Straight Talk, which I'm pretty sure it isn't. If you don't want to pay for service every month or don't want to pay for data then just buy an iPod touch. An 4S without service or data is a big waste of money.

I updated to the new iTunes last week. Today I plugged in my 4th generation Shuffle to add some new songs. The shuffle appears in Devices, but when I try to add songs, I'm not getting the progress bar at the top of the screen, so I'm assuming the song isn't being added. I tried ejecting the Shuffle and plugging it in again, and I got a message that my iPod needed to be restored before it could be used with iTunes -- even though the screen also said the Shuffle is up to date on the software. I finally gave in and restored it, but I continue to get the same message. When I eject the iPod and try to play it now, I'm getting nothing, and when it is connected to the usb port, the orange light is continually flashing. I've been trying to figure this out for about 3 hours now, so if anyone could help me, I'd be eternally grateful!
The 1st and 2nd gen shuffles do not have an automatic syncing mode, like later shuffles and the "big" iPods. It is maintained manually (or by using the Autofill feature).
If the iTunes sidebar (along left side of window) is hidden, from the menu bar, under View, select Show Sidebar. The shuffle appears in the sidebar, under DEVICES, when connected.
To add songs to the shuffle... Show a list of songs in the iTunes window. For example, you can select Music under LIBRARY (in the sidebar) to show your complete iTunes music library list. Select a song and drag it to the shuffle in the sidebar. You can do this with more than one song selected. Alternately, select the song(s), right-click the selection, and choose the command to Add to Playlist -> [name of iPod].
To remove songs from the shuffle... Select the shuffle in the sidebar. To the right, it's Settings screen is shown. Toward the top, where it says Settings, click on On This iPod (to the right). The list of songs on the shuffle is shown below. Select the song you want to remove and press Delete on the keyboard. You can do this with more than one song selected.
NOTE: At the bottom of the shuffle's list of songs, there are controls for the Autofill feature. You can also use Autofill to fill your shuffle from your music library or from a specific playlist. -
I have recently upgraded my iMac Intel G5 iSight (iMac5,1) to OS 10.6.8 and now the internal mic does not work with skype or facebook. I can here static when playing back clips. Do I need to update firmware or reload old system parts. I have zapped PRAM. The blue indicator in system audio panel will appear for a second as I slide the bar for internal mic but then it disappears. Is there a fix?
The sound seems very faint but can here static on playback.

I'm new to GB and I'm trying to record solo vocal with a backing track. I can get the track running OK but I can't seem to record. I think when I press record the backing track mutes and I need it running.. Thanks in advance!
guess what it says java file. So yes i'm sure. Sarcasm. Not the best way to encourage a total stranger to help you. Then there's
Sorry if i wasn't more clear but was that response needed?No it wasn't needed, but I'm not the one asking for help so I have the luxury of not worrying too much about it. It's extremely frustrating trying to drag relevant information out of someone, and makes one less inclined to bother.
Anyways, there's still nothing in this thread that actually explicitly says "there is a file called VolcanoApp.java in the directory where I'm running javac from" and I really can't be bothered banging my head against the wall any longer. You've made a silly mistake, or a false assumption. We all do it from time to time. My advice is, take a break, go for a walk and re-visit this in a while. You'll probably spot the mistake right away. -

i cannot purchusse movies on my apple tv. it keeps telling me that i need to update my billing info. i have done this and i keep recivimg the same message!!! help!!!
You don't. the ipad is not a backup/storage device. it simply mirrors the selected content of your computer. The sync is one way - computer to ipad. The only exception is itunes purchases.
Did you fail to maintain a backup copy of your computer?
If so, not good.
You may be able to purchase a third party program, not supported by Apple, to get the other music. -
