Need to get the exact time of each picture that I saved ( maybe as a excel sheet or word )

Hi guys,
I am actually a new labview user. I have successfullly been able to save pictures. But unfortunately I got two problems. The first one is that I need to use two cameras at the same time. The program I have so far is for one camera. The second problem is that I need to get the exact time for each picture saved in the profile.
I would appreciate if someone can help me with that. Anyway plz find attached the subvi.
Regards,
Abbas

Hi Abbas,
First, I notice that you are using IMAQ for USB. Is there any particular reason you are not using IMAQdx? This is the newer, supported driver for use with USB cameras that supports acquiring from multiple cameras at the same time.
Check these two articles:
Can I Acquire from Multiple USB Cameras Simultaneously Using IMAQdx?
Can I Acquire from Two USB Cameras Simultaneously with NI-IMAQ for USB Cameras 1.0?
And also this example (if you camera does not support acquiring from multiple cameras at the same time):
Toggle Between Multiple USB Cameras
As for timestamps, some cameras output them with the frame timing. However, usually this is not a feature of USB cameras; if it is not, you can look into timing options within LabVIEW. Try playing with the property node for IMAQdx and the Acquisition Attributes.

I need to get the system time in Micro second

Hi,
In the java API there is a static method �curentTimeMillis�, but I need
to get the system time in Micro second there is a equivalent method? Or
there exists any suggested solution?
Thanks
Dany

Why do you need such accurate timing ?
I'd be suprised if anyone seriously relies on millisecond timing in
Java, never mind calling through to JNI to get microsecond timing.
If that's even possible in native code.
The garbage collector can cause delays/pauses in a java program and
throw timings off by at least 500 milliseconds, probably more under big loads.
If you just want a more accuruate way to reset a random seed, there's probably other ways...

I need to get the value of a text field that is located in another page JSP

I need to get the value of a text field that is located in another page JSP. How do I do that?

Well you see, I have a page at angelfire.com, which
does not support JSP. I want to call a script located
at mycgisever and then, when pressing a link on the
former page, the JSP page is loaded, and the script
get the value from the text field on the OTHER page.
Is this possible?I know nothing about cgi. But that should not prevent me from understanding what can and cannot be done, assuming cgi is sort of comparable with jsps.
I'm unable to understand your description clearly. Try to explain it better. Give precise steps that you intend to follow and I should be able to help you further.
So you have a page1.
You hit submit from page1.
That goes to the cgiserver.
From the cgiserver, programmatically load up the jsp.
search this for the text field.
Display it on your page2.
Is that what you are trying to do?
BTW, won't be able to help you with cgi scripting at all. Can help with Java and Jsp.

How can I get the logoff time of each db user from system view?

I can get the logon_date from gv$session.
Now,I want to get the logoff_date from some view or table.
I know that I will get it with trigger.
But,I am not will to user trigger for it.
Who can tell me which view or table will show the info?

But,I am not will to user trigger for it.Are you saying you are not willing to fire a trigger to gather this information?
I don't know of a table, if one exists, someone will know.
I say until you find a table, just write a SYSTEM TRIGGER on LOGOUT and place this information in your own table.

I need to get the current assignee for a given request using SOA's java api

I'm developing a spring app that interfaces with Oracle SOA suite and executes the actions such as approving requests using the api. I need to get the current assignee for each SOA Task this is dispalyed in the OIM console so it is getting it from somewhere. I tried getApprovers in the ITaskService api but this returns an empty list

I have checked it once again and there indeed are links for ALUI components for Solaris on SPARC at edelivery.oracle.com. (Officially ALUI supports Solaris on SPARC only)
If you have looked at Solaris x86, then you must not have found them. Please make sure that you are selecting the righ platform. Also, make sure that you click on the Aqualogic media pack so as to get the lists of the components included in it. (Point to Note: You need to go to the next level)
For whichever component you are not able to find, try looking for it in the Metalink (My Oracle Support) if you have a support contract.

How to find out the exact time in UK with daylight savings.

Hi,
how can i get the exact time in UK even if the daylight savings time is implemented in UK..,
now my code is implemented for IST ,how can i get the BST timings?
Thankx.

the setTimeZone method of SimpleDateFormat (actually inherited from DateFormat). Use it to set it to your timezone when parsing or formatting a date string for your timezone and set it to the UK timezone when parsing or formatting a date string for their timezone.
Edit: IOW SimpleDateFormat was the answer, not a question.

I can get the last time a patch was applied. What I need is this info for ALL servers.

Getting the last time a server was patched is a simple, single line of PowerShell:
get-hotfix -computername seadcweb10 | sort InstalledOn | select -last 1
What I need is to get a list of *all* the servers in Active Directory, and get this information for each.
I've tried variations of foreach , but I get errors.
foreach ( $p in Get-ADComputer -Filter 'OperatingSystem -like "Windows *Server*"' ) { get-hotfix -computername $p.Name | select -last 1 }
Get-HotFix : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
At line:1 char:97
+ foreach ( $p in Get-ADComputer -Filter 'OperatingSystem -like "Windows *Server*"' ) { get-hotfix <<<< -computername
$p.Name | select -last 1 }
+ CategoryInfo : NotSpecified: (:) [Get-HotFix], COMException
+ FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,Microsoft.PowerShell.Commands.GetHotFixCommand
What am I doing wrong?

Hi
The RPC server is unavailable
This error comes when any server is not pingable.
Make sure you are able to ping to all server from the server you are running the script.
Then give a try to below script :
foreach ( $p in Get-ADComputer -Filter {OperatingSystem -like "Windows *Server*"})
get-hotfix -computername $p.Name | select -last 1

I need to get the Current System Date and time in the format

I need to get the Current System Date and time in the format
*6/24/2009 11:30:29 AM*

I seem to be saying this a lot lately.
Google is your friend.
I googled "java current date format" and SimpleDateFormat featured prominently in the results.

In ios 7, how do I get the calendar to open each time in list mode?

In ios 7, on the iphone 5, how do I get the calendar to open each time in list mode? It always opens is strange new mode and goes to list mode only if I click the search icon.

For some weird reason beyond my comprehension, and I am a smart fellow I think; Adobe starting with acrobat/reader 8 has decided to hid the menu icon Ribbon (i guess you would call it) until you have a PDF open. In versions past if you had these icons on the screen you could actually use them to open Pdf's or create pdfs from scans.
Pesonally for me its a dumb idea. But was justified as allowing for more screen area to view. The guy that thought up the idea should be taken out behind the barn and given 10 licks for stupid ideas. :-)

Need to get the overtime hours worked for Report

Dear Experts,
We have configured Overtime for client and it is working fine.
But for custom report development we need to get the overtime hours worked.
We have searched in B2 cluster and not able to identify exact overtime table.
Request your suggestionsu2026u2026..

Hi,
after time elavualtion use t code PT66, in this t.code double click on the each month(period) then you can get the internal table like ZES, SALDO, ZKO. again double click on the each internal table, you can get the information through the time types. Like , now you want the overtime hours, 0903, 0904 with this time types you can get the each employee no. of. overtime hours.
ZL, ZES, SALDO, TIP entries are internal table , you could not get any results from this table with using se11, se16.
With PT_BAL00 with this report also we can get the overtime hours with the help of time events.
Good luck

While my friend was setting up his iphone, i used my icloud. So now, when i send him a message i get the exact same message from myself. How do i fix this?

While my friend was setting up his iphone because i had recently updated it for him he needed a itunes account to use for "bump" so i could transfer his contacts back. So i used my itunes and icloud account to sign in so he could download that because he didnt have any of those accounts. So when i logged in he was basically me, my name was his phones name aswell. Well i used "bump" his name was the same as mine. I got the contacts to work but now every time i send him a text message, (imessage) i get the exact same message from myself. How to i unverify him off of my icloud so i can be the only one using it?

The fact that the problem only occurs when iphones are texting you leads me to think that iMessage may be the culprit. The fact that it is only iphones using SPRINT however is weird. Try turning imessage off on both yours and your sons phones to see if the problem persists. If it does, it may be a carrier problem.

Need to get the exact time of each picture that I saved ( maybe as a excel sheet or word )
