PersistentStore is not persistent between the device restart
Hello
I use the PersistentStore to store a hash table with an integer simple mapping custom of POJO. It seems to work between the restarts the application, IE, I can totally my application and restart and persistent data are restored. However, after a reboot of the appliance, such as pulling on the battery, the data are there not more and everything is reset to 0 by default. Same thing happens on the Simulator.
I certainly call the commit() every time I change the contents of the table of hash and that in a thread safe way. Nothing appears in the journal of the events, or all exceptions...
It's with OS 4.6.0 and in this case a "BOLD".
One with ideas or similar issues that I could hurt?
Thank you.
Daniel
Right, I found the problem: all the objects you want to persist must implement the Persistable interface. Too bad there is no word about it in the JavaDoc of PersistentStore and PersistentObject and too unfortunate that PersistentObject.setContent () takes an object as a parameter instead of an instance of a Persistable implementation. That probably has to do with the fact that the implementation allows implicit persistables objects as the Java object representatives for more than native data types Hashtable and vector.

IMessage does not sync between all devices
My ipad/Mac will not sync with my iphone imessage. Until I reinstalled my Mac wasn't a problem. If I type a message to someone in imessage from my Mac or my iPad, it does not display in my iphone vice versa.
imessages from my iphone will not only do not appear in the other two devices, but the response I get will not pass to the device, sure I typed the message. Even the opposite effect. Messages and responses to Mac/iPad won't go on my iPhone imessage.
Should what setting I change to get everthing again between all devices sync?
Have you checked that you have activated the same send to and receive to address on all devices.

Hi all!
I have a question about using a DMM (PXI-4065) with VStudio 2008 and Measurement Studio 2009.
Because DMM are not always supported in .net, I downloaded niDMM.cs 3.0 wrapper of the web site of NOR.
I also downloaded example c# measure DC Voltsto compare with my request.
Both an example and my application fail trowing the exception [-1074118656] 'the device was not recognized. The device is not supported with this driver or version. " class constructor is called.
DMM = new InstrumentDriverInterop.Ivi.nidmm ("PXI3::12:INSTR", true, true);
I guess it is function of device PXI!
I also tried to use a VISA alias as "pippo" and then I tried to insert a device unexistent name. In any case the same exception was trown.
NOR-DAQmx 8.9.5
NOR-DMM 3.0.1
NI-VISA 4.6.1
NOR-MAX 4.6.2f1

Dear Sir.
Nice to meet you.
When I run the SMU-4141 "Adjust voltage Leve.vi niDCPower Cal" calibration function niDCpower version 1.8.
It shows an error "function of calibration is not supported by the device." (false cae)
But if I run the calibration function SMU-4141 "niDCPower Cal Adjust voltage Measurement.vi", (real deal)
It will work.
See attachments.
My equipment list:
Windows XP SP3
LabVIEW 2011
niDMM 3.0.5
niDCpower 1.8
PXI-1073 case with 2 cards.
SLOT2: SMU-4141
slot6: PXI-4071
Could someone tell me the solution?
Hi Peter,.
The calibration process indicates that the call of the function of voltage adjust NI - DCPower Cal calibrates both the output level of the device as well as the ability to measure of the device. It is even for the Cal of NOR-DCPower function adjust a current measurement.
You must perform a calibration automatic on the device prior to the initial audit of the device, before the adjustment process and before the final verification process.
I'm not sure I understand your question very well. Please let me know if I have not responded sufficiently.

Hi simonaces,
Thanks for posting on answers.microsoft.com
The error in the information provided is typical, as the music player is bursting at the seams. In case this is not correct, the manufacturer's website may have more information about the specific error on your brand of system.
MAKE A BACKUP OF YOUR MUSIC BEFORE WALKING THROUGH THESE TROUBLESHOOTING STEPS.
More specific information about this error may be found on the website of your mobile phone manufacturer.
Here are a few troubleshooting steps that can be useful for you, however, he will wipe away your current music out of the system.
1 connect the player to your PC via the USB cable.
2 open Windows Media Player.
3. go to the Sync tab or devices and remove all the contents of the drive.
4. go to the Tools menu and select Options.
5. Select the devices tab, select the Sony drive and click Properties.
6 uncheck 'create folder hierarchy on Device '.
Now, when music is transferred, it will be placed in the root directory of the flash memory without taking into account the structure of the file and which allows to consider all tracks and less cache used by indicating the complete error of the device.
Don't forget, make a backup of music before walking through the troubleshooting steps. The steps are designed to clear the music file and then not select a hierarchy to activate folder structure that would free the cache for storing music to.
Please let us know if that fixes the problem or if assistance is needed.

My HP DVD/ROM does not appear in the device under my computer Manager or when I scan for readers, most of the time. Every now and then it will be visible and I can use it but 90% of the time it does not exist. I tried the regedit fix, nothing. I tried the program Microsoft Fix It, it tells me it cannot locate a DVD/ROM. I removed, cleaned and reinserted my DVD/ROM drive, but no difference. I tried everything, except the upgrade to Windows 7... who will be my last resort.
Hello gargoyle28m,
If your hardware is not detected to upgrade to Windows 7 is not a resolution. This issue may be caused if the DVD drive is faulty or connections loose on the mother board. You may need to check the connections. I suggest you check if the DVD drive works on another computer. You can contact the manufacturer of your computer to help you with this problem.
Thank you

Ethernet adapter is not showing in the Device Manager
I have a vastro 460 with i3 with intel and Windows 7 32 bit. try to install the driver for the network card, but does not. Ping works but do not show in the Device Manager.
Any help will be much appreciated
Hi EMH.
You will need to install the Chipset Drivers first and later network adapter drivers. The IP address that you have ping is the local host and works, even when there is no network card detected.
Please download and install the NIC in the network section and the section Chipset Chipset drivers from the following link, by drilling in the serial number:

Is it possible to prevent the device restarts when I deploy an application?
Hello
Whenever I have deploy an application on my device (Blackberry 9780, OS6.0) to test the device restarts. Is it possible to deploy without having to go through this lengthy process?
Who knows what is happening behind the scenes!
There are simple things, like the establishment of the correct size at startup icon, which will mean that your device needs to restart after the installation.
