Can I queue a system event?
I have an application where the event handling is processed in the RunUserInterface() loop.
I would like to simulate pressing a sequence of command buttons and thus activate their callbacks, hence I would like to add a system event (EVENT_COMMIT on a given control) to the event queue to be handled in the event loop, (or just call their callback directly) - and then I need to add an event to the system queue to get back to my "simulation" subroutine (which I just implement as a call back as well).
I can of course add user events, but if I understand correctly, these events are not handled in the RunUserInterface() loop?
(How) can I add events to the system(?) event queue to be handled in the RunUserInterface() loop? Or do I need to set up my own event handling loop?
Sure - I just tried it, and it works as expected.
I created a MIDI region at about 3 1 1 1, selected it, opened up the event list, clicked on "Create" to enter the create events mode, and clicked on the "Meta Events" button to create a meta event inside that region (which by default, goes to the current position, which in my case is 3 1 1 1).
Change the "Num" value of the event to 52 ("Stop Playback" is displayed in the Length/Info event column).
Now, playing the song from 1 1 1 1 plays until it reaches 3 1 1 1 (where the stop event is) and Logic stops.
You can of course move the region containing the stop event to wherever you need it.
Simple as that - there isn't any more detail I can go into

So I upgraded my Macbook to Snow Leopard recently, and after starting it back up for the first time after install, I was greeted with a dialog to locate the System Events app. After some googling, it appears that this is caused when there are applescript applications included in the login items.
I didn't know what was up, so I just clicked the cancel button, and haven't seen the dialog since. Although now it appears that the couple of trivially simple applescript applications I've written will no longer quit, they have to be Force Quit. This is annoying at best. Is there any way to get this dialog to come back up so that I can correctly identify the System Events app? Anyone have any more information on this issue? Thanks!Well, turns out the system events.app wasn't the issue with my applescripts (it never IS Apple's fault, is it...). Fixed those, everything seems to be working fine. I still haven't figured out if there's anything I need to do now to help OS X out with that issue, but I'm guessing not? I'd assume that it's found/associated the file after start-up and should no longer be an issue.

Hello all,
I'm interested in how the AWT system event queue works. I'm talking about the EventQueue we can all retrieve using Toolkit.getDefaultToolkit().getSystemEventQueue().
My main questions are:
1) What happens to events once they get on the queue?
2) How do the AWT Components get notified of the events?
3) How is the correct AWT Component to notify determined?
I've done a little bit of Googling but haven't found anything explaining how the event queue actually works.
In case you're wondering, I'd like to know all this because I'm in a position where I need to mimick the system event queue's behaviour without actually touching it.
Any links to further reading, suggestions or comments are most welcome.
Thanks in advance,

My co-worker and I are not sure what the difference between Any queue limit set to zero and System queue reached its job limit are in the System Events.
Hi jlayton,
System queue limit is the sum of all queue limits you have defined. For example, if you have a system queue limit of, say, 100 -- queue A has 50 jobs active, and queue B also has 50 jobs active, then you will receive an alert System queue reached its job limit since it is set to 100.
Any queue limit set to zero. Note, this may also include the System queue. For example, if you want to gracefully stop Tidal, you may want to set system queue = 0 so that there are no active jobs. When you do this, you will receive an alert queue limit set to zero.

System Events got an error: Can't get current configuration of service?
I'm trying to connect/disconnect services through apple script, here is the error I'm getting for "Ethernet" "AirPort" (these services are configured in services tab)
I am able to manualy On/Off these services without supplying admin password, therefore it might not be privilages issue.

end tellHi Damian and welcome to Apple Discussions!
One suggestion: try
tell application "Finder" to open item 1 of docs
(without 'using "Corel Painter 8"')
As far as the Finder is concerned, "Corel Painter 8" is just a string of characters. And telling the Finder to open a file is just the same as double-clicking it: the Finder knows which app to use - as long as these are native Corel Painter 8 docs.
Hope this helps,

Windows 8.1 - Windows Couldn't connect to the System Event Notification Service service
I have an issue that has been bothering me for a while on new 8.1 computers. Standard users are not able to log into the computer on the first try consistently. They receive the error message: Group Policy client service failed the sign-in access is
denied. They are stuck at the logon screen.
If an administrator logs in (local or domain), they can log in but get a black desktop with two error messages. The first is Location is Not available - C:\Windows\system32\config\systemprofile\Desktop is unavailable. The second error message is a popup
balloon. It states "Failed to Connect to a Windows service. Windows couldn't connect to the System Event Notification Service service."
When a standard user attempts to log in, event viewer records three warnings. They are listed in order from oldest to newest
The winlogon notification subscriber <Profiles> was unavailable to handle a critical notification event. -Logged 9:14:44
The winlogon notification subscriber <GPClient> failed a critical notification event. - Logged 9:14:44
The winlogon notification subscriber <Profiles> was unavailable to handle a notification event. - Logged 9:14:49
After a reboot, users still have the issue. I noticed that the user profile services and system event notification service are not running though their startup type is automatic. They start after a minute or two.Hi Joseph__Moody,
Based on your description ,I assume it is a domain environment .First of all ,I would suggest you to try to update all the machine .
"I have an issue that has been bothering me for a while on new 8.1 computers"
Do you mean all the Windows 8.1 machine share the same symptom or just a specific one ?Did the machine work correctly before ?When did the issue start to occur ?Have you installed any third party software before ?Can we operate the machine when we login with
an administrator account ?
If the issue occurred with the specific machine :
"The first is Location is Not available - C:\Windows\system32\config\systemprofile\Desktop is unavailable."
Please try the following suggestions if we can operate the machine when we login with the administrator account :
Open Windows Explorer and navigate to: C:\Windows\system32\config\systemprofile and verify if it has the Desktop folder there.If the folder doesn`t exit, we can copy from C:\users\Default\Desktop location(This folder is hidden by default).
We also can try the following suggestions to have a troubleshoot :
1.Run "sfc /scannow"or "dism /online /cleanup-image /restorehealth" to check the health of the system files.
2.Perform a full scan with an antivirus software.
3."They start after a minute or two."
I suspect there is a third party service confilct here. Please perform a clean boot to verify whether there is a third party conflict here .
How to perform a clean boot in Windows
https://support.microsoft.com/en-us/kb/929135
If the issue occurred with multiple machines in the domian ,I would suggest you to check whether you have configured any logon scripts and logon group policy .We can remove the machine from the domain to have a troubleshoot .
If the issue occurred recently ,we can perform a system restore to recover the machine to a previous normal point.

i have a backup and sychronizing program called Synk that is currently unscriptable. I want to set up folder action so that when i plug various drives in this program opens the correct backup files and the program.
So far i have managed to get the program to open and i have managed to get the open dialog box up, i have also managed to get it to click the right button to start the process. Where this fails is when selecting the correct backup file. The open dialog box appears and i can see which one i want it to select, but i am unsure of how i get system events to select a specified item from the open dialog box. It also fails to initalize when the drive is inserted.
on adding folder items to this_folder after receiving added_items
if (added_items as string) contains "Humphrey" then
--set bup to file "Humphrey To University.sknd" of folder "Backup documents" of folder "documents" of "home"
tell application "Synk"

RichRichard,
Does this help:
tell app "Finder" to open file "Humphrey To University.sknd" of folder "Backup documents" of folder "documents" of "home"
It should open Synk for you with the target settings file.

I have downloaded IOS7 on my iPhone and all calendar events have disappeared. The general functions of the calendar have changed and are definitely not 'user friendly'. How can I retrieve my calendar events. Will Apple improve the calendar function or revert to the previous system. Even the typing function on IOS 7 is faulty - very slow to respond to the keyboard. I no longer enjoy using my iPhone. Can anyone assist. Thank you
Very strange! All of my calendar events have reappeared. This has happened one week after downloading iOS 7
The calendar however, is not easy to use.
The typing function on the phone has become even slower. Have to wait for each letter to show on screen. -

Hi, my system runs on windows 8 on hp laptop envy series. All of a sudden, system event log on service stopped, errors which prevented the system to log on services. It displayed error of STOP 0xC000021A when i use system restore to roll back to previous
configuration. Also when I tried to refresh my pc, it says i can't do changes as log in was switched to prevent the changes by notification.I don't know what to do next, I tried to put recovery dvds which I made when system was bought, now not at all working.
Internet is not active, not able to resolve by trouble shooting and system taking lot of time to get dsktop. Previously I used to get my desktop in 10 seconds. Now its 10 min. May be I m infected with virus. My files, they are there. I tried to transfer some
files by pendrive to another system, now the new system(where i put my files in another system) crashed, windows 7 system which does not display desktop, icons etc and not at all workable.
Also in my hp system, i m unable to open control panel. if its opened, it will not go off, when i use task manager, it says explorer and shuts down. I had to force restart the system. Please resolve something to get my hp laptop workable. I m waiting for
my MS thesis to be working on that. My files are locked and no way to transfer, I fear of infected by virus to another computer also.
Pls give instructions to hw to set my hp laptop at the earliest without losing any of the files. Idon't want to reinstall and lose all the data for timebeing. Else, inform me the option for copying data safely. I tried to change the adv startup and recovery
by changing the boot sequence by DVD but this also shows error 0xC000021A and asks us to see the details. I didn't understand all this. Pls help asap.
Thanks
venkata
STOP 0xC000021AMV
If you can boot either from the win 8 dvd or in safe mode we need the DMP files
We do need the actual DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.
WE NEED AT LEAST TWO DMP FILES TO SPOT TRENDS AND CONFIRM THE DIAGNOSIS.
Please follow our instructions for finding and uploading the files we need to help you fix your computer. They can be found here

System Events not working correctly with Acrobat Professional
Hey Guys, I have a script that I have written that automatically enables security settings on a PDF through Acrobat Professional. Because of Acrobats poor scriptability I am forced into doing much though System Events.
This is not a major problem... however when activating some settings in the security settings, often warning Alert dialog boxes appear when you tell System Events to enable particular settings. These Alerts do not have a title... The only way I have been able to get the script to deal with them is with the following code:
if title of front window is "" then
tell front window
click button "OK"
end tell
end if
I guess this is an ok solution... bit hard to identify windows when they don't have titles...
BUT this is not my main problem. The main problem is that the script gets to one of these alert dialog boxes and just sits there... It sits there for like 10 seconds and then it performs the "click button "OK"" command.

Reporting Services not automatically starting. System event log 7009, Application event: 18456
For the past month (since Oct 11,2012) reporting services (SSRS 2008R2) is not starting after the server is rebooted. The service is set to automatically start and starts manually without a problem. The system event log contains the following error:
Event ID 7009: A timeout was reached (30000 milliseconds) while waiting for the SQL Server Reporting Services (MSSQLSERVER) service to connect.
SQL logs :
The SQL logs has many "Event 18456 Login Failed, State 38" errors when the database engine starts. I assume clients conections are failing because the databases aren't online yet. None of these 18456 errors coorespond to the account reporting services
runs under.
The SQL logs indication Event 7009 occures before the "ReportingServer" database is online so im assuming there is a dependancy but I don't know how to avoid this.
This problem is occuring on a number of our servers running SSRS (if not all)
Any ideas?
PaulHi A141695,
For Event ID 7009, you can try to do the steps below to resolve it.
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
3. Right-click Control, point to New, and then click DWORD Value.
4. In the New Value #1 box, type ServicesPipeTimeout, and then press ENTER.
5. Right-click ServicesPipeTimeout, and then click Modify.
6. Click Decimal, type the number of milliseconds that you want to wait until the service times out, and then click OK.
For example, to wait 60 seconds before the service times out, type 60000.
Quit Registry Editor, and then restart the computer. For more information about it, please see:

Continuous "36888 Schannel Errors" in System Event Log when NOT connected to Internet
We are hoping someone will be able to assist with us this very strange issue please ?
We are using Windows 8.1 x64 Enterprise with Office 2013 and the latest Symantec Endpoint Proctecion v12.1.5 installed. They are managed using SCCM2012 in a large AD domain environment
When our workstations are NOT connected to the internet (only local intranet) the following errors appear in SYSTEM event log almost continuously (several times a minute).
Event ID:36888 User: SYSTEM OpCode:Info Level:Error Source:SChannel
"A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 70. The Windows Schannel error state is 11."
The process associated with these events is "Local Security Authority Process"
When an internet connection is enabled for these machines these 36888 errors will suddenly stop !.
An event "Error 36887 "A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 40." Is also occurring on these machines but only occasionally.
As a result, We suspect there must be a process continuously attempting to connect to an internet service and failing ?.
Some of the things we have tried so far;
- We have disabled all non-essential services (e.g. Windows Store Service) one by one but this didn't fix.
- We have tried disabling Tile updates on Start
- We have tried a bunch of different Group Policy settings to disable different combinations of TLS/SSL in IE config.
- We have searched the internet forums and tried some suggested fixes but this combination of error state and error code seems unique ?.
It doesn't happen on our Windows 7 x64 workstations that have much same apps & configuration.
Any advice or suggestions would be greatly appreciated !
Thanks.Hi Makes006,
This Event ID 36888 occurs if a user tries to access a web site using HTTP but specifies an SSL port in the URL.
We can try clean boot to troubleshoot whether this issue is caused by a third party program .

If there is no sensible impacts on operating the machines ,we can try to disable this log by modify the following registry key value to 0.
