How can I check if a file exists in CVI Real Time?

It would also be nice if the help file designated whether functions were supported in real time or now.
I tried this:
if(GetFileAttrs (DataFileName,NULL,NULL,NULL,NULL) == -1)

You can check if a file exists in CVI Real-Time using GetFileInfo function.
The CVI help provides a list of functions available on CVI Real-Time here: CVI Real-Time Functions

How can i check if a procedure exists in a certain database version

So today i became really frustrated after noticing that the Oracle SQL version on some computer I needed to work on was 10.1. The problem with that was that I needed a procedure called "xmlserialize". I browsed the documentation for it, but I didn't see anything like "since 11.0" or something similar.
So.. how can I see what is the first Oracle SQL version that supported some procedure?
For example, when I check a class definition for Java, I consult the javadoc :
http://docs.oracle.com/javase/7/docs/api/java/math/BigInteger.html
and there there's a field called "Since". For BigInteger ( it's just an example ), it says "Since: JDK1.1", so I know that if I'm using a JDK version earlier that 1.1, I won't have that class.
Is there some similar information for Oracle procedures/ functions/ features/ etc?

>
Let me be more explicit. I've searched for xmlserialize function.
The only place on the website that holds information regarding this function is this page:
>
To paraphrase sybrand - that's utter nonsense. I have never found only one reference to anything on the web.

How can i check the license file installed on the server CCM 6.1.4

Hi;
i have installed the CCM 6.1.4; and now i want to upgrade to 8.5, but i don't remenber witch type license i have uploaded ( normal or Hospitality).
how can i check the license file installed on this server???
thanks.

Hi Matthew,
I think your idea should work just fine, but you will need to work with;
[email protected]
To put together the proper license file due to this change called the "License MAC"
Customer Impact from New Licensing Procedures
Cisco Unified Communications Manager on VMware on Cisco UCS B-Series Blade Servers uses a different licensing model than Cisco Unified Communications Manager on an MCS server. The MAC address of the NIC card is no longer used to associate the license to the server.
Instead, the license gets associated to a license MAC, which is a 12 digit HEX value created by hashing the following parameters that you configure on the server:
•Time zone
•NTP server 1 (or "none")
•NIC speed (or "auto")
•Hostname
•IP Address (or "dhcp")
•IP Mask (or "dhcp")
•Gateway Address (or "dhcp")
•Primary DNS (or "dhcp")
•SMTP server (or "none")
•Certificate Information (Organization, Unit, Location, State, Country)
This hash of these fields is called the LICENSE MAC
Note : Once there is a change in any of the parameters that creates the License MAC, it will
give you 30 day grace period to generate a new license file for the CM based on new license
MAC.

Well if you got the Phone Pggray43 at a Local Corporate store in your Area) you should be able to return it as long as you have all the contents.! Phone, Charger and any other accessories that came with it the Box of Course.. As long as you have not went past the 14 Day return.. the store can go over what you used as in Air Time and Data..
Now if you've went past the 14 Day return you be Liable to pay a E.T.F = Early Termination Fee the fee for this is around $300 so hopefully you have not went past the 14 Day return window the Manager if Available is the one I would talk to tell them your on Social Security and you just can't afford a phone as this I'm sure they'll work with you to get something solved..
Hope ya have Good Luck.! b33

How can I check if a file is opened?

Hello,
I have a problem:
I want to check if a file is existing or not, and if it exists, I want to check if it is opened.
The following actions should be taken:
1. File exists => no error message, everything's ok
2. File does not exist => NO error message, create the file later
3. File exists but it is opened => notify user (Ok message)
4. path does not exist => notify user (Ok message)
How can I do that? I have problems to check if the file is opened.
This is what I have done until now:

LabVIEW 7.1 (!)
Greetings Johannes
Using LabVIEW 7.1 and 2009 recently

The error checking method is probably the best, most efficient, and cleanest way to do this (only one case structure needed). But here is a somewhat more "rube goldberg" way that does do the job thinking somewhat linearly. If the directory doesn't exist, then the file won't exist. If the file doesn't exist, then it can't be open. So first you check if the directory exists, if it does, check if the file exists, if it does check if it's open. Not a fan of these nested case structures really, but it is a way to do it.

How can i check the unzip file has finished unzip process?

i am using 7zip to unzip the file. java program can check the unzip file has finished unzip process?
Edited by: rayray2008 on Feb 12, 2008 7:14 PM

Downloading and burning Linux or Windows ISO images for example with a single flipped bit can cause system instability nearly impossible to track down, and not otherwise detectable. An MD5 checksum (OR SHA) check will quickly detect any such transmission errors. Not something anyone I know bothers to use unless it's important data. The temporary fix of changing the about:config setting, then expanding to full screen in downloads was working. But now, based on my interpretation of comments made on the authors Sourceforge page, Firefox has made updates that prevent the MD5 Reborned Hasher from working in Firefox at all. If that's true, I would really like to know the reason. With all this talk of NSA spying, I would think more people would be interested in making sure someone isn't tampering with their downloads. I have no idea. But I do believe the wonderful volunteers at Firefox need to figure out a way to make this valuable piece of security software whole again. Thank You.
PS: For those needing to verify a file, you might want to try the "Microsoft File Checksum Integrity Verifier" kb841290 . It's old, but does large file MD5 from a command prompt.

How can I check all the files on an external volume?

I recently had a problem with my external where the directory got messed up. Disk Warrior seems to have fixed it, and I've run both that and TechTool Pro on it to check the files and so far both have said they're fine, but I'm still worried. I have quite a few files on there and each time they test it takes only a few minutes where if you verify say, a DVD of files it takes 5-10 minutes just for that, and that's 4GB to 1TB.
Is there any way I can test all the files on the volume, much like verifying them, to see if there has been any corruption or data lost?

You're a very helpful person, aren't you? Lol.
I have checked a bunch of video files that were on my external pre-trouble that I was able to transfer to my internal drive and run perfectly. Unfortunately there are far too many other files to check them all, all of my music on there as well as all my font, work and resource files so there's tens of thousands of files on there. Checking them all manually is not an option.
Thanks for the reassurance though. Hopefully at some time in the near future Blu Ray will be cheap enough that I'll be able to back up all my data to disc regularly, until then I'll just have to rely on my external.
Thanks for the help!

If I buy an iphone second hand, how can I check that is valid and purchased for real?, If I buy an iphone second hand, how can I check that is valid and purchased for real?

Hello
I'd like to buy an iphone second hand and although I trust the source I'd like to be able to check with certainty that the phone was bought instore.
I was thinking to ask for the receipt and check the serial number. is the serial number written on the back of the phone and the recipt(if the phone is sealed)?
Similarly, if I buy an ipad 3 or 4 second hand, how do you check this again?
Please let me know with some details about this.
Thanks
Anthony

Ask the person you are buying the phone from to provide the original proof of purchase for the phone. If you do not know the seller personally I would be very cautious about purchasing the phone. There are many many stolen, hacked and jailbroken phones out there and these will only cause you grief down the road.

How can I get updated data in sub VI in real time?

Hello.
I'm making application using Labview 7.0.
What I want to do is the data acquisition changing some parameters. I get the data each time
I changed variable parameters. I can do it in sub VI by inserting array component into 'for' loop.
As loop iterates, the parameter sets are changed, and new data is inserted into array by 'replace subset array'.
New data fills the array by each iteration.
However, I can't bring this result array to my main.vi. Sub VI gives me the result array only when
its processes are done. I want to display the data while parameters changing is still on
the way.
Are there any solution to get the output of sub VI while the it is not finished yet?

Hi Joewun:
Yes, you can update that data in real time.
It's done using references and property nodes.
You can Create Reference of an array in your main VI
In your SubVI, create a new Input to an array reference, and insert a Property Node function into the For where you update the value, and select Value property.
This way when your array updates in the SubVI you will see the changes in your main VI.

Right SubVI.

How can I control external MIDI devices from my PXI Real-time system?

I am trying to implement a psychoacoustic experiment using an external MIDI device that can be used to shift the pitch of a speaker's voice.
I have a 8176 controller in a 1002 chasis with the 6052E IO card. I would very much prefer to run the system in real-time mode (rather than win XP), and need to control the MIDI device through one of the interfaces on the controller.
Any suggestions?
Thanks in advance,
Frenk

Hi Frenk,
one way would be an analogue to MIDI converter.
There are some out there (ask for music equipment)which can convert an analogue signal to some MIDI controller signal. This way you could control the pitch shift with an analogue output of the 6052 in realtime.
Hope this helps
Regards
Stephan

Hi,
If your requirement is to insert in one table and if the record exists insert into other table the merge statement doesn't work

How can I check for corrupt files/ programs?

I have just received a call from a scammer, but before I realised it wasn't real, they logged on to my Mac (using TeamViewer) and had control for about five minutes. At best, they were just trying to hard-sell me some anti-virus protection, but I'm worried it's much worse than that.
Once I suspected something, I instantly cut the connection and shut down the Mac, but I'm worried that they may have placed some programs on my Mac to either send information/ files or just to track internet key strokes.
Apart from the obvious (speaking to my bank, etc.), is there something I can run on the Mac to see if it is clean?
Urgent help appreciated.

The only way you can be sure that the computer is not compromised is to erase at least the startup volume and restore it to something like the status quo ante. The easiest approach is to recover your entire system from a backup that predates the attack. Obviously, that's only practical if you know when the attack took place, and it was recent, and you have such a backup. You will lose all changes to your data, such as email, that were made after the time of the snapshot. Some of those changes can be restored from a later backup.
If you don't know when the attack happened, or if it was too long ago for a complete rollback to be feasible, then you should erase and install OS X. If you don't already have at least two complete, independent backups of your data, then you must make them first. One backup is not enough to be safe.
When you reboot after the installation, you'll be prompted to go through the initial setup process for a new computer. That’s when you transfer the data from one of your backups in Setup Assistant.
Select only users in the Setup Assistant dialog — not Applications, Other files and folders, or Computer & Network Settings. Don't transfer the Guest account, if it was enabled.
Reinstall your third-party software from original media or fresh downloads — not from a backup, which may be contaminated.
Unless you were the target of an improbably sophisticated attack, this procedure will leave you with a clean system. If you have reason to think that you were the target of a sophisticated attack, then you need expert help.
That being done, change all Internet passwords and check all financial accounts for unauthorized transactions. Do this after your system has been secured, not before.

You could use Migration Assistant to pull the data from the Time Capsule to the new computer.

How can I check DATA in BSEG for PO date corresponding (time period)

PO date (BSTDK)
but in bseg I only can find BLDAT AUGDT
and it is also can not find in bkpf
only can find it in VBAK

not every BSEG relates to a sales order so it does not have the field directly. You have to link back to VBAK (or maybe VBKD) maybe via the document flow table VBFA.

How can I check what model hard drive is in my Time Capsule?

... without opening it, that is

You are correct in that Apple used and uses different drives even in Time Capsules with the same model number. I think you are correct on the WD Green disk, If I remember the test reports that I've read...but don't have handy at the moment.
But, it is not true "server grade", as Apple advertises. The "server grade" models require more power and run warmer. Apple is trying to limit heat on the Time Capsule.
If you really need to know what drive you have, the only way to find out is open up the Time Capsule.....very carefully. It's not hard to do. This will void the warranty, of course, but who will know?
Use a hairdryer on "high" to heat up the rubber pad on the bottom for about 10-15 minutes so that it will peel from the metal case neatly. Remove the 10-12 screws and you are there.
Don't touch anything near the power supply capacitors
