How to get intimation about DAQmx Physical Channel invalid value encounter
Can anybody tell me that if a DAQmx Control gets value from a configuration file( .ini file ) and the value is invalid (does not exist in the available physical channels list) than how I can be programatically intimated. I couldn't find any property node of DAQmx Physical channel Control which tells about that the current value feeded to the control is invalid.
Thanks Alan, I have got a better soloution from you in another thread launched by me with title "How to get "Browse list of any DAQmx control in array form". In which u suggested of using DAQmx 8.0, which I have downloaded and used the property node DAQmx-Device>>DO.Lines to get an array of all Physical channels(DO category) of all devices. The value taken from that configuration file is searched in Physical channels array and if no match found than the value is invalid.

DAQmx physical channel constant error
Hi all,
I am trying to get the labview 10.0 working in opensuse 11.4. I installed the components and all of them seem to be working fine.
The PCI card is also detected by labview. When I tpe lsdaq on the command line. I get the following output
Detecting National Instruments DAQ Devices
Found the following DAQ Devices:
NI 6025E: "Dev1" (PXI8::15::INSTR)
But when entering "Dev1/ai1" or "Dev1/ai0:3" in the DAQmx physical channel constant I get an error saying invalid channel name. How do I get rid of this error?

Solved!
Go to Solution.Hey Justin,
Thanks for your reply.
I am working with labview 10.0.
I installed DAQmx 8.0.2 but it did not help. DAQmx is not ideally meant for labview 10.0 and probably that is the reason why it does not work.
The installation also does not seem to go smoothly since it looks for support files from labview 8.6 and previous version which do not exist. I have attached the messages after installation of DAQmx.
Let me know if you find some way out.
Thanks,
Chiran

How To Get AppleToCare About You (iOS7 wifi solved)
I recently encountered the now seemingly infamous iOS7 upgrade wifi bug. After upgrading to iOS 7.1.1 my wifi was subsequently knocked out. After reading skimming the forums and trying a few of the suggested work arounds I was still unable to get my wifi working (at all). I decided to wait for the next software update assuming Apple would fix the bug. What can I say? I like to believe people are inherently good and accountable. No such luck. When I went back to the forums for a better understanding of the problem I was (somewhat) surprised to discover the magnitude of the issue. For me, the end result was a new FREE iPhone despite my warranty expiring several months ago.
Try all of the (reasonable) suggested solutions. They did not work for me but that does not mean they will not work for you - no seriously actually try them:
I turned off wifi and bluetooth, set the phone to airplane mode, turned it off, left it off for several minutes, turned it back on - Nothing.
I reset my Wifi Router - Nothing.
I reset all Settings - Nothing.
I reset my Network Connection - Nothing.
I did a Soft Reset - Hold down the power and home buttons simultaneously and do not release until after the screen goes black and the apple logo appears. - Nothing.
I did a Hard Reset (aka Factory Reset) - BACK UP YOUR PHONE FIRST. I connected to iTunes and performed a backup then hit restore (within iTunes). This can be done directly from your phone but if you're here because you're experiencing wifi issues your phone is probably not backed up to iCloud.
Genius Bar. BE POLITE but firm and know your stuff. They don't owe you anything. Well Apple kinda does, but the employees in the store didn't break your phone so don't act like they did. At the end of the day Apple wrote a buggy code and isn't acknowledging the problem or compensating it's loyal customers. The only way Apple will be held accountable for leaving so many customers out to dry is if customers demand it. However, the Genius Bar is not the place to take out your rage. When I went into the Genius Bar I explained the issue I was having and the steps I had taken in an attempt to fix it. I let her run all the tests and tricks she wanted (knowing full well they weren't going to work). She politely explained to me that I would need to purchase a new phone. I explained to her that I could not, in good conscious, give a company money to solve a problem that they caused. (Some people are crying conspiracy on the part of Apple to get people to buy new phones but I haven't drank the punch yet. - I only took a sip.) I asked if she could do anything else for me. She told me that AppleCare might be responsive to my issue despite my expired warranty as they are a separate entity from Genius Bar and have more authority to help customers. I (sincerely) thanked her (several times) for helping me and asked if I could speak to a manager just to see if there was anything else they could do in store. She said absolutely and that she would "grab a nice manager". I spoke with the manager and briefly explained the issue. I then explained my issue lies primarily with Apple's business model. I, personally, take excellent care of my devices and expect them to last more than a year. I expect that when I buy a device with a premium reputation and a premium price tag that it should be supported by the company for a reasonable amount of time. The iPhone 4s is still being sold in stores and Apple is already neglecting 4s customers - (WILDLY) unacceptable. The manager was very nice about it and expressed that I made valid points and my frustration was justified but yet no solution.
AppleCare. After stopping in the Windows store to check possible new phones I trudged home. (Despite my fortunate result I still have a sour taste in my mouth from Apple's method of forcing customers to spend money unnecessarily on constantly changing but marginally improving products. I'm now seriously considering a Windows tablet to replace my aging MacBook.) Anyway, when I got home I called AppleCare and had a very similar exchange with the associate on the phone as I'd had in the store and was subsequently transferred my to a manager. Again, I was extremely polite to the associate and grateful for the help but made a firm point of dissatisfaction with Apple. When I got on the phone with the manager our exchange was quite short but he acknowledged that because the issues arose from a software update causing a hardware problem Apple would compensate me. (Yes, software can physically affect hardware. The CIA uses code to blow up bomb detonators masked as cell phones. It's dope. There's a TED talk about it.) In the end I got a new iPhone for FREE (with a standard replacement fee - ok Apple you won that round. It's still significantly less money I'd spend on a new phone from Apple or elsewhere).
Moral of the story: Be polite but demand more from the companies you made (filthy) rich. Companies don't care about their customers as much as they should and we can't sit around and wait for them to behave themselves. We need to demand it (even if it ruins our Sunday afternoons). I'd also like to make it known that several times during these exchanges that I'm probably ditching Apple for good. If you use that approach you should be ready to back it up. I'm probably not going to buy another MacBook as I'm a grown up now doing actual work and Apple's inability to play nice with others makes it really difficult to run much of the software at the level I need. (Programmers, you know what I'm talking about!) As for phones, I require much less of my phone. Beyond, you know, using it as an actual phone, I really only use the GPS, music, photos, and web browser so I've always been a fan of the iPhone. After this, however, I don't know if I'll be getting another. I don't like spending money when I don't need to, especially if it's just making fat cats fatter.

How to get information about limitation Internal Memory on device
hallo ..
have some question here, so please some person able to answer my questions
1. How to get Information about limitation internal memory on device
2. is possible to improve internal memory on Blackberry ( move apps on external memory )
3. any tools to get internal memory activity ?
thanks for this people who joins here, hope we can share more information about blackberry ..In addition...
There are three types of potential memory on a BB: 1) Application Memory, 2) Device Memory, and 3) Media/SD Card Memory.
Application Memory -- This is the most crucial; it is the protected (not user accessible), dedicated, and fixed (in size) space that is available as the destination for the installation of applications (plus some application storage, overhead and such). You cannot touch AppMemory. You cannot improve the maximum AppMemory that your BB has. It is what it is. Applications can only install here...there is no option.
Device Memory -- This is space on your BB that you can touch to store files, pictures, media, etc. Typically, it is not terribly large, but it is available to you.
SD/Media Card Memory-- This is what it says...your SD card, for you to store files, media, pictures, etc. It can be as large as your BB OS can support...see this KB:
KB05461MicroSD card sizes supported by the BlackBerry device software
On some devices/OS levels, you can only see "File Free" (Options > Status), which I think is equivalent to AppMemory. On other devices, you can see all three memory usage levels (Options > Memory). Here are some guidelines to use:
KB02843What is the Low Memory Manager feature on the BlackBerry smartphone
KB14320How to maximize free space and battery power on the BlackBerry smartphone
KB14213Call logs, SMS text messages, and email messages are deleted from the BlackBerry smartphone
Lastly, it is always important to properly close applications when you are done with them. Using the Back or the Red key will not do this -- those leave it to the app to decide what to do...and some will leave themselves resident in memory, consuming resources on your BB, slowing the overall performance. Rather, to close an app, press and select "Close" or "Exit"...that will force the application to be closed, freeing up for your new use the resources it was consuming. Some apps will always remain running (typically -- BBMessenger, Browser, Homescreen, Phone, and Messages)...but, you should still close them properly - especially the Browser...if it is left on an active web page, it will not only consume extra resources but battery power as well.
Further, anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure. Some have taken to doing this on a regular basis as a preventive measure...some as frequently as once per day. Others have obtained the QuickPull app to automate a simulated Batt-Pull.
Good luck!

Problem with DAQmx Physical Channel control
Dear LabVIEW community!
I have installed LabVIEW, v13.0f02, 32-bit on my PC. The problem, which I face, is that DAQmx Physical Channel controls, which are used in VIs inside the LV projects, sometimes don't show me the list of DAQ devices - I can't expand the list at all. I push the button to expand the list, but nothing helps.
But when I create VIs outside the project, and put there DAQmx Physical Channel control - everything works well.
Note: devices are simulated via MAX.
Is it some kind of bug in 2013 vesrion of LabVIEW? Because while using LV 2012 I didn't have such headache.
The only thing that helps now - is to restart PC (laptop) several times; b/c restart of LV doesn't help.
Can anyone suggest, what it can be, and how to fix this problem?
Thank you very much in advance!Thank you for your answer!
The point is, that this bug is independent from the code. DAQmx Physical Channel controls don't work even when I'm trying to use NI examples - for instance, Strain - Continuous Input.vi; Voltage - Continuous Input.vi, etc.
I have such simulated via MAX devices: NI USB-9213, NI USB-9201, NI cDAQ-9172 with NI 9217, and 4 NI PXIe-4331 modules.
Also, what I have noticed - front panel doesn't visualized fully (I send you the screenshot). When I'm moving mouse pointer over it, those part, which were under the mouse pointer, became clearly seen. And when I minimize, and then restor FP, it becomes fully clear visible.
And also, this story happens when LV project is open. If I close opened projects, and open only single VIs, everything works smooth.
Thank you very much, I hope, that this information will be useful to solve this problem.

DAQmx physical channel to string
Hi Labview forum,
I have a variable DAQmx physical channel variable.
I would like to write the physical channel used to a file.
Is there a way to convert the physical channel selected to a string for writing to file?
Or to access a property node which stores the channel name in string format?
Regards,
Jamie

I am not sure how to use "Scan from String" for these unique data types. Where can I find the format codes for physical channels and enums. I guess ENUM is U32 or something like that but I have no idea what a physical channel is.
You have to use the Scan From String to convert your string to the enum. But as Dennis said, just wire your string straight into the Physical Channel input.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to get information about creation of a virtual machine on a Hyper-v host.
Hi,
How to get information about creation of a virtual machine on a Hyper-v host?
I need: host name, time created, creator user.
I saw in Hyper-V-VMMS but I found info about movements of VM between hosts.
Thank's in advance.
Denius ValiantFor Host Name * Created Time Use This Command In PowerShell
Get-VM -Name (Read-Host "Type Your Vm Name") |select CreationTime , ComputerName
and for Create User , As i know you should see on Event Log .
Go To Event Log Viewer--->Applications And Services Logs--->Microsoft--->Windows--->Hyper-V-VMMS--->Operational
You can see in Event Log who create the Vm.

HOW TO GET INFORMATION ABOUT THE CLIENT MACHINE AT DATABASE LEVEL
HOW TO GET INFORMATION ABOUT THE CLIENT MACHINE AT DATABASE LEVEL USING 10g Database and 10g Application Server
we have developed an application using oracle forms 10g with
oracle database 10g and Application server 10g
Application uses a single Oracle User name to connect to database
where as at Application level there are different users (these are not database users)
Now how can we get the information about the user/his machine etc. at database level. earlier in 6i/8i we use to get by using
USERENV('TERMINAL')
we had written a triggers on tables on Insert/Update where we used to update a database field Last user terminal with USERENV('TERMINAL')
but not this information is comming to be the machine name of application server where as we wish this to be the machine name of Client. Any Way outs
thanks
Chaand Kackriahi, you can use the sys_context function, like this:
select sys_context('userenv','current_user'),
sys_context('userenv','os_user'),
sys_context('userenv','host'),
sys_context('userenv','ip_address'),
sys_context('userenv','instance'),
sys_context('userenv','sessionid'),
sys_context('userenv','terminal')
from dual;

How to get information about cursor? I had only a reference on it.
Hello
How to get information about cursor, that I receive in my procedure as a reference. For example I need to know, a number of columns. I know nothing about this cursor, except the link on it.
Best Regards, Kostya Proskudin!However, I would seriously reconsider what you are trying to achieve.
It looks like you are trying to write some ultimately generic cursor processor. i.e. pass any cursor and process it in some generic way.
Good design should include knowledge of what is expected to be passed and that knowledge can be put into the code.
Generic code is inherently difficult to maintain and debug and will never 100% deal with all possible situations e.g. even if you know the table being queried in the cursor you can't rely on the data dictionary to give you all the returned columns if some of the returned columns of the cursor are computed columns.
Be careful you aren't writing something that's going to cause problems later. -

DAQmx physical channel error message
Hi,
I am new to Labview but I managed to create a new analogue voltage input task in Measurement and Automation Explorer. I am using DAQmx create virtual channel VI but I am getting an error message saying that "required input physical channel is not wired". Any idea why I am getting this error message. Also what is the difference between using DAQmx Assistant and using VI's like DAQmx create virtual channel, DAQmx timing etc.Any help is appreciated.
Thanks
Duran

error2.JPG 171 KBThe first VI 'Create Virtual Cannel' has an input called physical channel. This needs an input. Right click on the terminal and select Create>Constant. Then you can select the channel (something like Dev1/ai0).
To your 2nd Q: The assistant is a fast way to configure your measurement. You can later also convert it to the VIs you use now. Using the VIs gives you full programmatically control of the task. (The meaningful phrases are 'configure' and 'full programmatically').

How to get information about file owner in UNIX
Dear all
I would like to write a file management program in Solaris 8 using Java.
However, I don't know how to get the file owner and file permission information
by any Java class. Please advise.
Sincerely Yours
Mr. Voravit H.I fear there will be no pure java solution, because file owner and file permissions are platform-dependent issues, especially about the gory details (groups, executable / sticky / setuid-bits, ACL etc.)
AFAIK java supports only the notion of a file's being readable or writeable but nothing further.
On the other hand, some (even popular and wide-sprread) platforms / file systems do not have the notion of the owner of a file.
So you will need some platform-specific solution like running an external command or calling the C function "stat". -
How to get info about the mobile, like screensize...
hi,
i need some info about the device my midlet is running on.
how is it possible to get info about the screensize, screentype(color/black) and perhaps devicetype or modelname?
i already read it somewhere but i didn't find the source again.

mmklthx,
the example below shows some basic information.
Display myDisplay = Display.getDisplay(this);
Displayable dis = myDisplay.getCurrent();
int high = dis.getHeight();
int width = dis.getWidth();
boolean isCol = myDisplay.isColor();
int nubCol = myDisplay.numColors();more detailed information about model, aren't available through the standard api, on blackberry's there some restricted apis that provide these device-type and other detailed information...
for more basic information, just look at the class-methods from display and displayable...
