File/directory info behaviour

Hi,
I'm having an issue with the file/directory info VI (and more file I/O VI's) in labview 7.1.1.
They produce a popup error message by themselves which I need to suppress for my own error handling.
Any solution for this ?
Regards,
Marcel Janssen

The automatic error pop-up is not specific to those VIs, but is a general LV behaviour. Basically, each node that has an error and doesn't have its error terminal wired into something causes these pop-up to appear. This can be disabled in the options menu.
However, I would strongly advise against that - error handling is very important. To avoid the pop-ups all you need to do is wire the error cluster and handle the error. In this case, check the error number. If it is an error you want to ignore, pass an empty error cluster on. If you don't want to ignore it, pass the original error cluster.
To sum it up - always use the error wires to pass the error data and handle the errors properly. It will allow you to know where the error is in case you have it. Leave auto-error-handling on just in case you forgot to wire an error cluster somewhere.
Try to take over the world!

i dont know how to fix it because i really don't understand how this VI give out the error, and I dont have very well understanding of the simple error handler...
i was going through the forum and found this infomation that is useful

"file/directory info" of file .lnk

When i use "File/Directory Info" with a file .lnk, a local link, Labview attempts to gather info about the linked file. For example if i have "link to C.lnk", it returns info about C:\. How do i get info about the link itself, i mean the little .lnk file?

Hi,
I'm not going to be able to solve your problem, but I just wanted to say I had a similar problem in the past.
While writing a recursive file tree program I wondered why one directory kept repeating itself. I finally located a *.lnk file which was pointing to the parent directory. Voilà. LV kept looping thinking that there were ever-deeper directories there.
The only way I found of getting around it (apart from Windows calls) was to simply ignore *.lnk files........
Not great I realise but it's all I came up with at the time.
Another method is to create a small batch program to list the *.lnk files in a directory and parse the output to a file which can then be read and analysed. Windows itself has no problems with lnk files.

The following error comes up when I try to install the updated Firefox:
"The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again."
When I follow the instructions in the error message, it shows that my user name has read and write access. There are a couple other items that are read only. I tried to change this to read and write, but the Sharing and Permissions options are greyed out and will not let me change them. What is the work around for this? I would really like to install the new firefox.
Thanks.

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default('''This will NOT delete profile info such as bookmarks and history'''):
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!
Thank you.

System Profiler Content File Directory Location?

Hello,
I recently changed out my microprocessor in my PowerBook G3 because my old one was not working properly. All works fine now as it is smoothly running 10.4.11. However, I look in system profiler and the serial number has changed to the new microprocessor and does not match the sticker on the bottom on the machine. I managed to modify the "About This Mac" and "Login Window" serial number just fine, but I am stumped regarding system profiler. I did research and found that in 10.5, you can manually input the serial by finding a "SMBIOS" type file architecture in the extensions folder of System>Library. My question is:
Where can I find the system files that give System Profiler its information. or Where can I find the equivalent in 10.4 to 10.5's SMBIOS system files.I appreciate any advice. Please indicate the entire file directory so I can easily find the location of the files I need to modify. Have a nice day.

I suspect that System Profiler gets the serial number either by an internal call to the I/O registry which in turn has gotten it from the logic board firmware, or else directly from the firmware itself. If either of these mechanisms is correct, then there are NO files that carry the serial number, and therefore I think there is probably nothing you can change. This may be incorrect, but so far I've seen no evidence of a datafile that has this information.
By way of background, here is my understanding. Hopefully I will be corrected if I am wrong:
A file is a particular type of data structure, a collection of bytes assembled by the operating system in a specific way. Files usually reside on physical storage devices such as disk drives, and persist even after the computer is turned off. A user with sufficient privileges can generally access the information stored in a file.
There are, however, other types of OS data structures in the "kernel," below the level of the user interface. These structures are not files - it is not that they are "hidden files" or "system files" - they are not files at all. These data structures exist in a protected space that users cannot alter.
ioreg -l | grep IOPlatformSerialNumber | awk '{ print $4 }'
I have no idea exactly "where" this piece of information is coming from, meaning the serial number that appears. It would be greatly appreciated if you could help me track down exactly where on the system the terminal command here is pulling this info from. It clearly gets it from some place, but it just may not be something we can see on the system as an object.
According to the link I posted earlier, the ioreg terminal command directly displays (but cannot alter) the I/O registry. This data structure is not a file, and does not exist in the filesystem that you access via the GUI or via Terminal filesystem commands. Even worse, the link said:
the Registry is not stored on disk or archived between boots. Instead, it is built at each system boot and resides in memory
What this means is that the I/O Registry resides only in RAM - it is completely destroyed when you turn off the computer, and gets rebuilt when you start back up. And again, it is not a file.
That's why I said "This doesn't sound promising"!
there has to be a way to override the "connection" between the dynamic database itself and how it obtains information from it.
If System Profiler.app does either read the I/O registry or read the firmware directly, then this instruction may be hardcoded in the app itself. I don't know this, but if so then I don't think there is any way to get it to look "somewhere else."
Good luck, but I think this project is going to be "The Impossible Dream"

When I download a page a message says cannot find zip file directory

When I try to download a page a message appears after the download time saying in part that "cannot find zip file directory". This message appears on all downloads I attemp.

Here are typical layouts for the iTunes folders:
If you have upgraded from version 8 (or earlier) to iTunes 9 (or later) at some point, then your media folder (everything inside the red outline) may still be called iTunes Music instead of iTunes Media. The extra Music folder inside the media folder is used if you have allowed iTunes to Upgrade to iTunes Media Organization (iTunes 9) or used File > Library > Organize Library > Reorganize files in the folder "<Media Folder>" (iTunes 10). Depending on your choices for Keep iTunes Media folder organized and Copy files to iTunes Media folder when adding to library plus a little bug in which one build changed the name of the file storing the choice of layout it is quite easy for some of your files to be organized according to one layout and some the other.
It is possible that in the upgrade to Lion iTunes has been installed with the current default options while your library is based on an older structure. Use Get Info. on a missing track, click cancel when asked to locate it and look at the path given on the summary tab. Now look for the actual file with Finder. Post both paths back here and we can try to make sense of the problem.

I have to select a file – get Info – and change – open with and change from preview to another program and CHANGE ALL everytime I boot up

Why do I have to select a file – get Info – select – open with – and change from Preview to another program and click CHANGE ALL with every file extention everytime I boot up.

Back up all data.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -Rh $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
The first step should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary.
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
resetpassword
That's one word, all lower case, with no spaces. Then press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

How do I find my CC Files Directory?

Hello!
Very new to the Creative Cloud.
Trying to figure out the most basic thing--where can I find the Creative Cloud Files Directory? I want to be able to automatically backup my Photoshop and Indesign files, just in case my computer crashes.
This site: Creative Cloud Help | Manage and Sync files --tells me if I save my files in this magical folder, they will automatically sync to the Cloud.
Where is this folder? I'm using a Mac. I searched for it in Finder with no luck.
Do I have to download another app?
Help!
Thanks,
Super Newbie.

File, get info, does not allow me to add grouping

This function used to work - File, get info. I could then change Artist, Album, Grouping, Genre, etc. Now for some reason, I can get the window to pop up, but everything is grayed out. I can see the info but cannot edit it. The only thing in black for editing is the start and stop time for the song. I don't want to edit this. I need to add a grouping title. This function used to work before the last program upgrades. Does anyone know why this might not be working? Is there a magic box somewhere that needs to be clicked on? Please help.

I had to go to were the songs were location on my hard drive and chance the security to allow full control then I could change it on iTunes

i followed Michal BLOG /people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
Requirement :
1) I am able to get the Target file name as same as the source file name when i check the ASMA in Sender & Receiver Adapter , with out any UDF...............this thing is OK
2) I took One field extra in the target structure Like "FileName" & I mapped it Like
Constant(" " )--UDF-----FileName
I Checked the Option ASMA in Both Sender & Receiver Adapters
Here iam getting the Target File name as same as Source file name + Source File name Info in the Target Field " FileName".
I Dont want to get the Target File name as same as Source file name. I want like Out.xml as Target file name.
If i de-select the Option ASMA in Adapters means it is showing " null" value in the target field "FileName".
Please Provide the Solution for this
