Tab Control Lock ? File Permanent Delete ?

I have couple of questions.
I have a tab control that I use for displaying test metrics during run-time. The first tab has a bunch of graphs. Whenever I browse to other pages in the tab during run time, the graphs do not autoscale. So I want to lock the tab for a particular amount of time when the test is in progress. Is there a way to do it ? I am not able to find a property node that would do it.
Also, I am deleting some temp files generated by my code after test completion. Is there a way to permanently delete it ? [I do not want these files in the recycle bin]
Thanks
Kudos always welcome for helpful posts

(1) Create a property node for the tab control, select property: disabled, and wire a "1" to it to disable, then change to 0 to enable it again later.
(2) How are you deleting the files? If you use the delete function from the file I/O palette, they will not end up in the recycle bin. Your program should do the cleanup as part of the exit code automatically.

Is there anyway to recover files permanently deleted in trash after a two month period?

I deleted some files that I thought I transferred to an external hard drive. However, after 2 months, I realized that all of the files did not transfer and I deleted them in trash about two months ago. Is there anyway to recover these files?

Probably not. All I can suggest is you contact a recovery service, but it's expensive and since you've been using the machine for over two months, most likely they're overwritten.

Deleting old Time Machine Back ups, locked files wont delete?

Will unlocking them help-if so how do you unlock? I can open with Text edit but due to years of caution when not knowing what I'm doing causes more problems I ask before doing things-grin (Suppose it shouldn't matter since all I want to do is trash them????)
The file in particular is the boot file boot.efi. Trash basket is still full presumable until I can delete.

Catalog not showing up - lrcat.lock file ??

hi. it seems as though lightroom may be corrupt. i really have no idea - please help! this morning i was working in LR. everything was fine. i shut the computer down as i normally would and i just came back to an empty LR. when i open it, i backed up but then no catalog appeared. nothing. when i tried to open recent, as well as several back ups, nothing will appear. most of the menu options are light grey, meaning you can't access them (e.g. import file, open recent, the catalogs are light gray, i can't even see "about adobe ps lr"). what is this? when i try opening a back up, nothing.
i also notice a file that comes up when i try to open a backup. it's the same name but ends w/ lrcat.lock
please help!!
april

With LR closed is there a Lightroom Catalog file in the pictures>lightroom> folder? is there also a lrcat.lock file there? If there is the .lock file there delete it.
If there is a Lightroom Catalog file still there double click on it to see if LR opens.
I have never had to utilize a back up file to recover so not sure what you need to do to recover from there, maybe someone else can advise.

I sent Firefox to the trash on my mac but can not empty the trash because of locked files. I want to do a fresh install because the update made it impossible for me to get into my e-mai account. how do I delete the old firefox?

re: uninstalling by moving Firefox to the trash: i received the following message: There are some locked items in the Trash. Do you want to remove all the items, including the locked ones, or just the unlocked items?
I have tried to un lock and to remove all items and have been unsuccessful - repeatedly.

Try:
* http://support.apple.com/kb/TS1402 Unable to move, unlock, modify, or copy an item in Mac OS X
Open the file information via one of these methods:
* Right click on the File or use the File menu and select "Get Info"
* Mark all files and press Command + Alt + I
In the "General" tab remove the check-mark in "Locked"
Trash and delete them.

How do I PERMANENTLY delete files I have deleted?

''Duplicate post, continue here - [https://support.mozilla.com/en-US/questions/806424]''
I have deleted files, but cannot find the way to permanently delete these filles. Previously there was an icon that read: Empty Recycle Bin. I cannot find the recycle bin.

Your situation is not good, then. You will need to erase your hard drive and start anew. Boot from your installer DVD for the OS X version you have installed on it.
I hope you have backups because it's not likely you can backup at this point.
Clean Install of Snow Leopard
     1. Boot the computer using the Snow Leopard Installer Disc. Insert the disc into the
         optical drive and restart the computer. After the chime press and hold down the
         "C" key. Release the key when you see a small spinning gear appear below the
         dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, set the format type to Mac
         OS Extended (Journaled, if supported), then click on the Partition button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.

What is the easiest way to permanently delete tabs so that they don't come back

No matter what I do I can't permanently delete tabs. I will close them all and the next time I open Firefox they are still there.

See:
* http://kb.mozillazine.org/Preferences_not_saved
It is also possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
* http://kb.mozillazine.org/sessionstore.js
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).

I have an iMac purchased in May 2011. OSX Lion 10.7.3. I deleted backup file from the external hard drive which operates from Time Machine.
Now, the trash can will not empty some of the files deleted from the backup harddrive.
The trash contains-- File folder: "Core Services" which contains a locked file: "boot.efi".
It will not delete.
How do I get the trash can empty of these files?

Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think?

How do I enable opening firefox from two different computers sharing the same home directory without having to delete a lock file (linux).

I just don't want to have to delete a lock file - which has a purpose - in order to use firefox simultaneously from two locations on the network - where the home directory, i.e. .mozilla directory - is located

You need to use two separate profiles if you want to have two Firefox instances open at the same time.

Make the tab control a control and not an indicator. If you want to write
to it you need to create a local variable.

Can't permanently delete song file from external hard drive

Hi Guys,
I want to be able to delete actual song files from my external hard drive as well as from my iTunes library in one easy, lazy step, via the iTunes window. I am not interested in finding and manually deleting the files through my external hard drive.
When I hit delete it only deletes the song from my iTunes library but not the actual destination music file aswell (from my external hard drive). I am aware this is because my external hard drive is not the original "Music\iTunes\iTunes Music" destination that the apple crew have designed and so I am not offered the option of sending the file to the recycle bin or "trashing it" when I hit the delete key (this permanently deletes the file).
I am also aware that I can find the music file destinations and delete them through the iTunes window by hitting "CTRL & R" or by the "show in windows explorer" command. I am not interested in these options either.
Basically, I have 20,000 songs to clean up and don't want to have to take my laptop with me to my grave...
I suspect there is some way of changing things around, possibly via some particular parameters to be set in the "Edit" > "Preferences" > "iTunes Music Folder Desintation" command area but still haven't been able to crack it.
Any help would be welcomed with open arms.
Cheers.
Labia.

Camoracer,
You are right. Pardon me. The majority of the music that I was trying to delete off my external hard drive was in a separate folder (on the external hard drive), not in the directory specified in my iTunes preference settings.
Problem solved!!!
This should also be a lesson to those who believe a one step delete function (from iTunes library and actual music file) is not possible when the music files are stored on an external hard drive (or other storage medium for that matter). I have read a host of other forums who say a one step delete function is not possible without additional software.. Perhaps these posts were from the authors of the software trying to make a $.
Cheers.

How do I delete files permanently from a usb flash key? On my mac (Yosemite 10.10) it's telling me the files are deleted, however on plugging key into television they're still there

I've a problem I've never come across before and it's how to permanently delete files on a usb flash key? I've just migrated from using Windows for 15 years onto Apple iMac and had been deleting files easily and permanently from the key on Windows without any hassle and thought I'd done the same on my iMac but seemingly they're still there as the tele is showing them when key is plugged in, BUT they can not be seen on iMac. I wondered why the key wouldn't take anymore files after, what I thought was, deletion and now I know why-imac hasn't deleted them!
I've actually gone into Disk Utility and formatted the key in it's usual FAT32 format to finally delete the files. Anyone any ideas as to why this happens and how to solve this please?
Many thanks

In addition to what Drew wrote, remember the Mac has a data fork and a resource fork.
Here is an old thread but a nice recap by Dr. Smoke
._Files
Note that the ._file files you note are the resource forks of Mac files you copied to the drive from your Mac, and these are only visible when you use the Flash drive on a PC. These are normal and indicate the Flash drive is already formatted for Windows.
When you copy or save a file from a Mac OS X system to a Windows shared volume or a Windows-formatted disk, the Mac creates two files: the data fork (xxx) and the resource fork (._xxx). This is called Apple Double Format and is normal. The resource fork contains additional data about the file that is exclusive to the Mac that cannot be saved otherwise on Windows-formatted disks. This is new with Mac OS X, as documented in Mac OS X: Apple Double Format Creates File Name With the Prefix '._'.
The resource fork files (._xxx) are necessary if you want to copy the file back to the Mac and retain the metadata. The resource forks of files are invisible when they are used on the Mac: the Mac OS Extended file system (aka HFS Plus or HFS+) uses forked files, with a file having both data and resource forks.
You can delete the resource forks on the Windows disk if and only if you don't care about losing the resource fork information should you copy them back to the Mac, such as comments, image preview icon, etc. Some Mac applications use the resource fork data, so deleting the resource fork can be problematic if you copy the file back to the Mac. Likewise moving the file while not also moving its associated resource fork when using the data on a PC can result in problems when using some files again on the Mac.
You can't prevent the resource forks from being created if you copy or save files from the Mac to the Windows share or Windows-formatted disk via Finder.

How do I permanently delete music files from itunes AND my computer (without going to the folder to delete each item)? It's a windows system. I've tried 'reset all dialogue warnings' as I've been told to do but no luck. Files are still in Itunes folders.

Solved! Music was in Itunes folder but not in Media folder within that. It doesn't seem like a very user friendly system so far!
