Wait for the entry?

Hi all

I need to create a custom entry dialog box and the problem I encountered is that I can't figure out how to make my request to wait for the user to complete the entries in the framework. When you use a JDialog or JOptionPane application will stop running and wait for the dialog box to close. My question is how to do something similar without using a JOptionPane or JDialog. I just can't figure out how to get the same effect by using a JFrame or other component. I know I could just use a JDialog or JOptionPane to get input from the user, but I'm just curious to know how I can stop running and wait for the entry as the JOptionPane allows you to do, but without using a JOptionPane or JDialog.

Thank you for your help :)

: Edit:
I forgot to mention that the reason main I avoids JDialogs is I need the entry dialog box to be internal not external application I use mode exclusive fullscreen. And a JOptionPane does not allow me to add the other components too it such as JLabels and other GUI. I just need a way to get input from a component or internal window and wait for the entry as a JOptionPane or JDialog.

Looking for a Boolean function similar to or, but do not wait for the second entry in case he gets a 'real' a single entry

my program works in 2 processes in parallel inside a while loop and should stop when one of them ends.

How can I do? Uses the function 'Or' wire loop the stop condition will not do the job, waiting for the two processes to give their comments before running.

What I really need is a function that waits until she gets a 'true' through one of its entry and then executes without waiting than the other.

Y at - it such an option?

If not, does anyone have an idea how to achieve what I have described here?

Thanks in advance!

What you need is a "not synchronous or", i.e. "do something if Item 1 becomes real GOLD point 2 becomes true. One way that comes to mind to do is with a design of producer/consumer model (event), where the consumer is a State Machine with a shutdown state. Get 1 point to trigger an event (perhaps using a user event or property Value Change (follow the signs)) when it turns out true, and have it send to the consumer the Stop State. Download point 2, to do the same thing. Now one of them becoming true will cause the shutdown state be registered (without taking care of doing the other element), in other words, that becomes a real, (consumer) loop stops.

Storage VMotion - a general error occurred: could not wait for the data. Error bad0007.

People,
I searched through this forum and have not found an answer that works in many positions out there, I say to myself that I would ask him once again.
Here's the context:
We have 12 identical Dell M600 blades in 2 chassis with 16 GB of Ram, 2 x Xeon E5430, they are all connected to an Equallogic PS 5000XV iSCSI SAN on a separate iSCSI (vswitch1) with 2 cards network dedicated network and dedicated switch, console svc iscsi dedicated, dedicated VMkernel port for iscsi access. Net access (vswitch0) contains port groups VM for our various networks and a console port and vmkernel svc for VMotion with 2 separate NETWORK cards as well.
We are running ESX 3.5 U3 and VCenter 2.5 U3 on Win2k3 R2
VMotion works between all servers, Storage Vmotion works for most machines, HA works and the value 2 host failurs with no monitoring of vm, DRS is set to manual for now I have a few machines on the local stores that I complete my rebuilt LUN, there is no set of rules for DRS and VMware EVC is enabled for guests of the Intel. However, I'll just describe one machine to do svmotion below.
Here's the problem:
I'm trying to Svmotion via svmotion.pl - interactive, a Machine to Windows 2000 with a virtual disk and a virtual RDM. I am aware of the requirements for the RDM and required parameters for svmotion, independent is not selected for the RDM, and I also have svmotioned several machines linux and win2k3 with the same configuration without problem. In the interactive session, I choose to individually place the disks and I chose the virtual disk to only the virtual machine to be moved, essentially, as I saw it move vdisk virtual machine and then copy to the pointer of the RDM.
The use of the processor in this machine is about 25% average. but I try to run migrations at the time the lowest. and The Host it itself shows only about 5.5 GB of the 16 GB of RAM used. so I think we're good on the RAM. the volume/datastore that I'm migrating from has 485 GB free and the volume/datastore I migration towards a 145 GB free. the VM virtual disk is only about 33 GB.
I run the script the windows version of the RCLI svmotion. and when to begin the process, I get the following error at around 2 percent of the progress:
"Since the server has encountered an error: a general error occurred: could not wait for the data." Error bad0007. Invalid parameter. »
After searching around, I found the following hotfixes to the U2 release notes
- Migrate.PageInTimeoutResetOnProgress: Set the value to 1.
- Migrate.PageInProgress: The value 30, if you get an error even after the setting of the Migrate.PageInTimeoutResetOnProgress variable.
I've made these changes, and I still get the same error.

The vmkernel on out of memory error, I had that before. And vmware support recommends setting 800M Max service console memory. And I did it and have no problems after that.

See if that helps the issue.

HumanTaskActivity does not wait for the user to act
Hello

Proc2 I stole the activity of each of the branches, I invoke another process called PROC3 from the e-mail as PROC3 entry.

PROC3 contains only HumanTaskActivity.

By the time wherever I start my PROC2, he calls PROC3, but in HumanTaskActivity PROC3 does not wait for the response, it gets full without sending email.

Any help would be very handful for me.

Thank you
VIKI
VIKI,

You can run just PROC3? It work? Except that there is a problem with the assignment of the user / group in this task? Users of human tasks has the correct permissions / roles?

I suggest that you follow all the steps in this article to resolve the problem.

Optimize Windows Vista for better performance
http://Windows.Microsoft.com/en-us/Windows-Vista/optimize-Windows-Vista-for-better-performance

Start stuck on "Please wait for the Local Session Manager."

I would say that this problem started a couple of days. Went to start my laptop (Toshiba) and he sat on the "Please wait" message forever.

Had no problems to start in safe mode. Looked up various ways of addressing the problem.

Was able to change the resume date and back a few weeks ago. Still no luck. Happened to read something on a printer Epson being perhaps the problem driver (it was installed a day before the date of restoration chosen). Uninstalled the drivers, computer still does not start.

Tried restarting running. I do not have the CD it came with Vista, but it was an option when you hold F8 during startup (I think?) Couldn't find any problems.

Ran check on memory. No problem either.

Changed settings for a verbose startup and ran a Diagnostic startup - all good for this. Then tried selective startup load system services... This is when the error occurs. When starting, it hangs on "Please wait for the Local Session Manager" and does nothing more.

I looked in the event viewer to see what came that time and a couple mistakes were:

Event ID 6000: winlogon notification subscriber was unavailable to handle a notification event.

Event ID 7026: the next (s) start or start failed to load system
spldr
Wanarpv6

It would be very useful for me not having to run my computer in safe mode automatically all the time, although it is useful that I at least have that option. Any help is greatly appreciated.

Hello

1. by chance your computer is connected to a domain environment?

2. as you mentioned in your article that you tried the selective startup, I want to confirm if you have disabled the services left 3rd after hide Microsoft services?

If you did not disable these services make sure you disable and then check if it works.

Please wait for the customer to political group - stop questions

Hello

I have problems with the closing of a machine. When the machine is connected to the corporate network, everything works fine. However, if the computer is connected to the VPN (1 hour or more) it is always suspended when it stops. First step in the shutdown process is:

Please wait for the system event Notification service.

This change after 3 minutes exactly. Next step:

Please wait for Group Policy client windows 7

is never exceeded (even after a few hours). Machine never off.

Under newspapers there are always these 4 events when the machine stops in vain:
1. 6005: the winlogon notification subscriber takes a long time to handle the notification event (Logoff).
2. 4627: the event COM + a system expired attempt to fire the method of logging on the event {D5978650-5B9F-11D1-8DD2-00AA004ABD5E} class for the Publisher and the Subscriber. The Subscriber has not responded within 180 seconds. The full name of the subscription is "ISensLogon2". The HRESULT is 80010002
3. 6006: the winlogon notification subscriber took 180 second (s) to handle the notification event (Logoff).
4. 6005: the winlogon notification subscriber takes a long time to handle the notification event (Logoff).
Sense has expired after 3 minutes while there is no event 6006 for GPClient and machine is stuck there for centuries (Please wait for the customer to group policy). I noticed in the system logs that before the machine hangs during the shutdown process there are these errors and warnings:
- 5783: the session configuration for the Windows NT or Windows 2000 Domain Controller \\server for the domain X is not admissible. The current CPP of Netlogon call on \\machine to \\server was canceled.
- 1014: name resolution for the name of the server has expired after none of the configured DNS servers answered.
- 131: NtpClient could not set a domain peer to use as a source of time due to the DNS resolution error on ". NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: the requested name is valid, but no data of the requested type was found. (0x80072AFC).
There is more than 1014 events for different servers and some 131. 5783 is always alone.

I did a group policy log, because I thought that I will be able to see where the machine stuck. Below you can see the part of the newspaper GPSVC when the machine stops in vain:

I excluded 1 GP machine and left on the VPN for a few hours, several times. He always stopped correctly.

However I tried with the VPN disconnection before turning off the machine, I even turned off WiFi but machine still hanging. If I tried to get GP results it takes ages before stopping the machine and he's stuck in the step "to get the user name. Gpupdate/force will never update policy (it stops at policy update...). I tired with the installation of different patches that has not solved the problem.

I think that there is that DNS issues while the machine is on VPN which led the GP cannot be applied. When the machine tries to close it is always somehow connected. There is no problem with the connection, no GP application script when the user disconnects, not roaming profiles.

Does anyone have the same problems? All machines are Dell with Juniper NC (VPN).

Thank you

BlackBerry Q10 in waiting for the new Q10 hit sprint but what will happen to my email?

Currently, I am waiting for the new Q10 hit sprint. but I hear that I have will no longer be able to use my email with the new blackberry blackberry.net. I currently use it as my email address. 1 it's true they won't E-mail blackberry and if so what steps do I need to take to make a smooth transition?

1. Yes, the blackberry.net email is no longer available... and quite honestly, in my opinion, it's a good thing. Blackberry.net email is not available elsewhere ON your BlackBerry, you can view it on the handheld device itself and no backup otherwise. Get a free gmail, yahoo or Outlook.com account.

2. read this: Article ID: KB33260 (hosted) BlackBerry e-mail address reference for BlackBerry OS 10

Then, create and start using another free email account now. When you finally go to the thread at BlackBerry10, you will have your solution in place for shipping the blackberry.net email account.

And there is nothing in V$ SESSION leader/block/line current. class obj # is EMP. current sql_id is the CREATE INDEX.
If anyone has an idea on:
-Why creating an index in line must wait for transactions that modified only parent table
-How to continue the investigation
-can or cannot reproduce in other versions
Thanks in advance,
Franck.

I guess you have a constraint foreign key between emp and Dept.

It's expected behaviours: since 11.1 any DML at one end of a referential integrity constraint translates into a mode lock 3 taken at the other end, and your phenomenon resembles a side effect of this.

When you try to create the index online that your session must assume that the other session (holding mode 3 on the emp and dept) may have changed the emp and dept, so it must wait for the session to the commit or rollback.

(I guess that in principle, he could walk the cancellation of the transaction see if EMP had in fact been changed - but maybe who was considered too complicated to be worth the risk to implement)

Updated - I just did a quick check to reproduce the effect on 11.1.0.7

For reference - here are a few notes on modes of locking and how the application has changed over time: https://jonathanlewis.wordpress.com/2010/06/21/locks/

Wait for the entry?
