Delay in event driven log file data writing? Please help!!!
System Information
Operating System: XP
Labview: 8.2
Force sensor data acquisition via DAQPad-6070E
Actuator: Actuator via MCS-3D controller
Programming Information
Number of events: 13
Position read: Reads the position and the force sensor data every second.
Move I & Forward: Moves the actuator forward with a define step size
Two actuators are made to travel certain distance. A force sensor is attached to the system. The aim here is to acquire continuous data as per the defined time wait (1 sec). The data is logged in a text file which gives the position travelled from the actuator, the force sensor data with a time stamp.
The issues I am encountering is during writing a file.
For ex: When even is activated ( Move actuator at defined stepsize) the event are logged into the log file but the positions are updated into the log file only when the next event is activated. So it means that the positions and the force values are updated into the logfile after the consecutive event is executed. If you see the logfile ex inside the attachment the red block explains the event executed but the position are updated in the next line (event). This file is just for example.
Please help here I am going wrong!
Thanks in advanced

Dear Method M
I find it out what was going on. As you mentioned that I was writing the values before the actuators achieving the final position, so I introduced a delay between the execution of two SubVI's. It isnt a clean method but it works.
thank you very much!

Windows Server 2012r2 Failover Cluster Event Trace Log files
Hi
The only documentation I can find regarding event trace log files (Diagnostic.etl.*) for Failover Clustering relate to Server 2008/2008r2, which state that the etl files should be in C:\Windows\System32\winevt\Logs.
I have been exploring a clustering lab for Server 2012r2 and cannot find these files in that folder.
Strangely the PS cmdlet Get-ClusterLog still works!
Where are the etl files?
TIAHi,
Please check if the log is available in C:\ProgramData\Microsoft\Windows\WER\ReportQueue\.
If not, you can use Get-ClusterLog with the Destination parameter to get the log file.
Destination
Specifies the location to copy the cluster log(s) to. To copy to the current folder use "-Destination ." for this parameter.

i recently have ipad but before i sell it i made a back up of it and by an iphone when i put all the date on my iphone some files and software did not install is there anything i can do to recover the lost data? please help
I don't think you're on iOS 5, I think you're using iOS 6. That's the latest version.
Unless you've used iCloud to back up your documents, you won't be able to restore them. And for future reference, you don't have to uninstall Pages to update your iPad anymore. Sorry about this. -
I re installed my original software and now I don't know how or if I can retrieve all my old pics and files!! please help i have a mac osx 10.5.4!!!
Not sure I understand how Migration Assistant is doing anything. I thought MA was for connecting your computer to another computer or volume and transferring files. I'm just not sure how you're using it. Like I said earlier, everything you do on your Mac overwrites more of what data may have been recoverable if there even was any. Not to kick you when you're down but this is exactly he kind of a situation where a time machine or other back up would have saved you a lot of heartache. I'm sorry but I don't think I can be of any help :-(

How do I delete movies from iTunes library? I have moved them to the iCloud and now only seem to have the option to hide the icon in iCloud. I am sure I chose poorly at the 'keep file' window. Please help. My Brain hurts… 18 plus movies need to go…. Thank you.
Instead of removing the music from the cloud or the iTunes library why not shuffle your music using a Smart Playlist which excludes the holiday music, or tracks that are not checked. For example, use this very simple Smart Playlist:

Problem with file archival. Please help
Hi Experts,
I have a requirement where XI reads input file via File adapter. Once the file is read successfully I need to archive it.
I also need to append timestamp to the archived file. After 10 days the archived file should be deleted.
How to achieve this in XI? Where do we specify the retention period for archived file? DO we have to write any script for teh same? IS there any sample script code available?
In file communication channel there is an option for archiving faulty files. Will this work for successfully processed files also?
Please help
Thanks & Regards
GopalHi Gopal,
The option of archiving the file is available in Processing Mode:
http://help.sap.com/saphelp_nw04/helpdata/EN/e3/94007075cae04f930cc4c034e411e1/content.htm
YOu can set the Processing mode to Archive to achieve your requirement.
retention period setting is not done in the communication channel.
Read more about archiving in this guide:

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on anoterh computer to help determine if you have an iPod or computer problem.

I have Windows 7 on a Dell. Open and play iTunes in the compatability mode and use Windows XP (service pack 2). Disregard any messsages to disable the compability mode. This has worked for me. I have also reinstalled iTunes and played with burn speeds etc. These ideas did not work. Compatability mode works.
