User event agent stopping USB from ejecting.

I recently updated my MacBook Pro to Mountain Lion and since doing so I have been unable to eject my USB as it says there is still a program using it, even though I have closed all applications. After having a search through the questions on here I found out that there is a process called 'usereventagent' that is causing the problem. I've tried force quitting the process but it comes back and the problem still persists. Will any of you guys be able to shed any light on this please?
Also, I have tried logging off, restarting all that stuff but nothing works.
Thanks in advance

I'm having the exact same problem. The process that is disallowing me to eject is 'UserEvent'. The only thing that helps is if I reinitialise the hard drive and use a different name. I've done this multiple times over the last few months, and the problem reappears after a while. I am unable to use ANY of the previous drive names, because UserEvent must be accessing the drives by certain drive names. So, I've had to become very creative with HD titles. It's so annoying, and I've actually lost data as a result of trying to solve this problem. It occurs even with a COMPLETELY blank hard drive following an initialisation. Is there any solution to this issue? Thanks.

User Event Agent (Not Responding)

In Activity Monitor, I'm seeing that the process called User Event Agent is in red letters and "not responding". Does anyone know what this means and how I can fix it?

Hi
Ive seen all the posts here but want to ask.
If i delete this bluetooth plugin am i going to be left with no bluetooth connectivity? I also use a Digidesign Mbox and had the drivers installed in my 10.4.11 system. I cloned that system to firewire drive and upgraded to 10.5 and let the set up assistant copy all my users apps etc from there into the new 10.5.1.
I cant find the digi design driver anywhere now in the 10.5.1 system. Can anyone say for sure that this driver was the culprit? If so where is it now?
Furthermore, i cannot sync my Nokia N73 as i could before i upgraded to Leopard. I wonder if this is because of the bluetooth plugin problem.
Sorry this is so badly written...
cheers

How to reset logs on Exchange 2010 after Event 518 stops backups from completing?

I'm only able to find references to resetting logs Exchange 2000 and 2003. I'm looking for info for Exchange 2010.
There appears to be some kind of corrupt logs issue with one of our mailbox databases. The corrupt logs cause the full backup to fail and because the full backup fails, the logs just get worse and keep growing.
The server has event ID 518 that says a log is "is missing (error -528) and cannot be used. If this log file is required for recovery, a good copy of the log file will be needed for recovery to complete successfully. "
How do e get past this and stop the backup job from trying to look for this log file and start over? I know that a full backup is supposed to clear the logs, but it will not happen because the backup never completes due to this log error.

its still same for 2010
Stop all the databases in the storage group.
Verify the state of each database file in the particular storage group. For information about how to verify the state of each database file, see the "Database states" section.
Perform one of the following actions:
If one or more of the databases are in a Dirty Shutdown or Inconsistent state, determine which transaction log files can be removed without affecting database consistency.
For more information, see the "Log files" section.
If all the databases are in a Clean Shutdown or Consistent state, you may remove all the transaction log files except for the current transaction log file. Removing the
current log file when all databases are in a Clean Shutdown state will cause a reset of the log file sequence. This does not prevent databases from starting. However, a reset of the log file sequence affects the ability to roll a
database forward from a previous backup if the situation occurs.
Copy all the transaction log files that you want to remove to a different location before you permanently remove them from the transaction log hard disk. Do not permanently delete the transaction log files until you have
successfully completed a full online backup of all the databases in the storage group.

Stop USB Drive unmounting at User Logoff

When my users logoff, the external USB drive is unmounted. The external drive is used to hold the users home directory. I have placed an entry in fstab as:
+*/dev/disk1s6 /Mount/LaCie hfs noowners 0 2*+
The mount works with +*mount -a*+
I got the system to stop from unmounting the drive at login with the command
+*defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool YES*+
which I found in another post.
At this point I have to issue a mount after as user logs off, which is pretty rare at my house, fortunately.
How can I change my systems behavior to leave the /Mount/LaCie drive mounted when the users log on or off?

Teresa Meerschaert wrote:
+*defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool YES*+
That command should keep disks mounted no matter who logs in or out. Isn't it working for you? Did you reboot after entering the command?

Starting/Stopping a polling loop with a user event.

I keep reading on this forum that placing a loop inside a user event structure is a bad idea because it disables other user events from triggering. However, it seems like a good idea to be able to start and stop a loop from a user event (like a button being pressed or de-pressed) and it seems like a good idea to not have the loop waist CPU resources while it does not need to be running.
So what are the solutions to this? Is a notification the best approach?
Attached is my solution. Is there a more graceful approach to this problem?
Aside: Why are boolean controls that are of the "Latched" mechanical action always pressed in after their event fires? For instance, the stop button on the attached VI? Shouldn't it be depressed after the user clicks on it because it is "Latch when released?" I've always wired "false" constants to 'variables' of these controls after the event structure fires, but do not find this approach very graceful.

If an error is generated on the first itteration, then the loop is terminated with that error line. Right?
Wrong! The loop cannot terminate until everything in it has terminated. RIght now it will stall at the event structure no matter what until an event occurs. At this time it is sufficient to get the error piped through the event structure. If you are worried about an error in creating the notifier (anything that happens before the loop starts), you shold place your entire later code inside a case structure wired to the error so the loops don't even start.

Can multiple event structures exist in the same block diagram? For some reason I was under the impression that there could only be one event structure that fires at one time. If that structure was in execution then no other Event Structures could fire.... if my information is wrong, then I like your solution. If it is right, then I don't like your solution .
Your information is wrong again. You can have as many event structures as you want, and all is well as long as all event structures can execute in parallel. So make sure they are in independent loops.
(If you would place two event structures in the same loop, both must trigger for the loop to complete the iteration, probably something that does not make a lot of sense. So don't do that!).

LabView user-event from external dll source

Hi!
I'm dealing with the following issue:
I use a CAN sniffer device, wich sends data over USB to a PC. The main goal is to create a vi that can process the incoming data. I already have a vi wich works with polling mechanism. It calls external DLL functions with the "Call library function node". The main problem is the polling mechanism.
I would like to recreate this vi so that it would work event-driven. I have an other application, written in C++, that does the same thing, and it gets interrupts from a DLL, when a new data is available in the input buffer.
The callback mechanism is implemented in the DLL.
In LabView I would like to do tha same thing. There is the "event case structure", but there is no option for defining such user-events, that i would prefer.
I have found a similar topic, there the solution is "occurrences". The occurrence is called from a DLL, too. But this solution uses the "waiting for occurrence to set", that is an endless-loop-like thing.
The other thing I've found is the ActiveX and .NET events. I don't know, probably that is the solution.
Anyway: is there a possibility to create such events, that can be generated from a simple external DLL and can be handled by "event case structure"? How should I do this?
Or how NI does this? I mean that NIs DAQ cards must use some similar methods for data processing. Is there some tutorial or support about it?
Thank you for your answer!

Hi Wiebe, From your answer i have a doubt that What it exactly means "If the dll is used from within LabVIEW". Also i want to know Is there any way to access the functuions defined in the .SYS file in Labview Environment. Regards,Jagan Can you be a litte more specific with your first sentence. I have no good idea what you mean. A .sys driver is usually a kernel device driver. This driver has to be started and run in the kernel subsystem which LabVIEW can not access directly. Such a driver is initialized using the CreateFile() Windows API. The returned handle is then used with other API functions such as ReadFile(), WriteWile(), DeviceIoControl(), and finally CloseHandle().Theoretically you could call all this APIs directly from within LabVIEW using the Call Library Node. In practice you do not want to do this even for fairly simple kernel drivers since the parameters for those APIs do get fairly complex in most cases, and you usually do also want to have some sort of asynchronous operation using events or such to make the driver access user friendly. All these things are most easily handled in a user space DLL written in C that exports a more LabVIEW friendly API that you can then import into LabVIEW using the Call Library Node. Usually most kernel device drivers do come with a accompagning user space DLL already, as this is the only sensible way of accessing such a driver. So you can usually look for the documentation of that user space DLL API and go from there trying to import that into LabVIEW using the Call Library Node. Even then it may not be easy at all if that API uses complicated function parameters and even completely impossible if it uses callbacks or such, requiring you to write a so called wrapper DLL that translates between the native API and a more LabVIEW friendly API. You don't have to believe me but I can guarantee you that if writing such a user space DLL or wrapper DLL is beyond your capabilities, trying to go directly about accessing the Windows APIs in LabVIEW to access a kernel device driver is going to make you squirm in real pain. And those knowing how to write such a DLL would never even consider spending the time to try to access a kernel device driver directly from LabVIEW. Rolf Kalbermatter

Do you have antiVirus installed on the sharepoint servers?
These folders may have to be excluded from antivirus scanning when you use file-level antivirus software in SharePoint. If these folders are not excluded, you may see unexpected behavior. For example, you may receive "access denied" error messages when files
are uploaded.
Please follow this KB and exclude the folders from Scanning.

How can I stop Calendar from formatting the location of an event?

When I enter the event's location (e.g. Concert Hall, 123 Main Street) Calendar breaks it up into multiple fields and sorts them alphabetically (e.g. "123 Main Street" and"Concert Hall"). It also tags each field with "!", meaning presumably that the location was not found in a directory or contact list. I'd like to stop Calendar from doing _anything_ "smart' to the location info and just display it exactly as I enter it. Any ideas on whether this is possible? Thanks much!

How to stop Windows from mounting a usb fat32 flash drive

Here's the problem. I have 4 identical Sandisk Cruiser 32GB flash drives. Windows has never mounted these drives in the past, until several months ago. Now Windows is mounting 2 of these drives but not the other 2. When the drives get mounted I end
up with about 5GB of files being added to each drive because they now show System Volume Information and the Recycle Bin. The amount of data added varies depending on the system I plug up to. On one Win 7 machine it can add up to 10+ GB. I would like to
be able to use the entire space for my backups but am unable to. These two drives are only used for Music and Videos. Is there a way to stop these two drives from being mounted in windows systems?
Thanks, Bill

Sorry but my figures are not exaggerated. Right now on this machine "System Volume Information" is showing as 3.2 GB and "Recycle Bin" is showing as 2.9 GB. I don't own these computers I use so I can't make changes to them such
as emptying the recycle bin. I only use portable applications from my flash drives on friends systems. By windows loading these two folders to my flash drives it it effectively stopping me from being able to use all the space.
Now as I mentioned in the first post, windows is only loading the SysVolInfo and recycle bin folders to 2 of the 4 drives. I am able to use ChkDsk on the two drives that are unaffected by windows but not on the other two. I get the message that windows
can't check the volume while it is in use and would I like to check it at startup. This always fails because, I think, These computers do not recognize the usb drives until windows is loaded. I have a work around for this in a utility that will unmount the
two drives and run ChkDsk and then remount them.
This doesn't answer the question though as to why all of a sudden this is happening to 2 of the 4 drives? And on several different machines? Windows does assign a drive letter to all 4 drives as it always has however the 2 drives without the system
folders are able to be scanned in windows without unmounting them.
I would really appreciate any insight into this behavior I could get.
Thanks, Bill

Importing my video from my event library into my project library, it shows the full width of the clip, but on the viewing section, it's zoomed in and cut the sides of the video off. How do I stop this from happening?

When importing my video from the event library to the project library, it's zooming in and
narrowing the width of my footage. How do I stop this from happening?

In the project, double-click on the clip to open the Clip Inspector. In the Clip tab you will see an item about two thirds down labelled "Stabilization". If checked, uncheck the box "Smooth clip motion".
Stabilizing clips causes a zoomed in effect, with the extent of the zoom dependent upon how shaky the footage is. There is a slider beneath the check-box labelled "Maximum Zoom" - this can be draggged back and forth to adjust the zoom effect if desired, once the clip has been stabilized.
You may have chosen to analyze clips for stabilization when importing to iMovie (that's a choice provided by iMovie upon import). If so, it's best to turn off an option in iMovie's preferences. Go to this from the iMovie menu item iMovie>Preferences. Click on the Browser tab and deselect (uncheck) the box labelled "Automatically stabilize clips that have been analyzed".
I prefer to import clips without analyzing, as this speeds up the import process. Afterwards, in the Event you can check for any overly shaky clips, then analyze them in the Inspector. If necessary, once dropped into a Project, you can stabilize them as desired. You can also stabilize clips directly in the Project without having to first analyze them in the Event.

How do I stop iPhoto from repeatedly closing Event title boxes when I am in the middle of entering a title?

How do I stop iPhoto from repeatedly closing Event title boxes when I am in the middle of entering a title?
This problem started several months ago. I have tried typing more slowly and typing faster; neither help.
It now takes me about four attempts to complete a title of about twelve characters, achieving about three characters on each attempt.
I am running iPhoto 9.4.3 on OS X 10.8.3 on a 2.93 GHz Intel Quad-Core i7 iMac with 12 GB of DDR3 memory.

As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

How do I stop mail from automatically opening when iCal events begin?

How do I stop mail from automatically opening when iCal events begin?
When an event is about to begin, the mail app opens and I'd like to turn that off since I don't use the mail app.
Thanks!

Hi
This may have something to do with the "Automatically retrieve invitations from Mail" option being enabled? Click on the iCal Menu > Preferences > Advanced. It may also be the Alarms setting? This is for 10.6 iCal so it may be in a different place for 10.5?
