How can I free RAM after running labview vi
I am trying to acquire 7 channels of data for 60 secs at 44100 Hz using a PCI-6259 card and LabVIEW. I am using the DAQmx Read polymorphic vi to acquire the data and the 'Write to Spreadsheet File' VI to write it. When I run the program for the first time, it will acquire and write the data, however when I try to run the program again it says the memory is full when it tries to write the data. I can close the program and reopen it and it will acquire and write the first time I run the program again, but it will not write the data the second time I try to run it. I have 3GB of RAM on a Windows XP system. The data is being acquired as a 2D DBL array and is creating an array that is 2646000x7. Can someone explain how I might clear the memory without having to exit and reopen the program? I would also like to increase my sampling frequency to get better resolution.
Take a look at these threads.

Do you really have to save DBL data?? could you change it to I32 or smaller?

How can receive the ACL after run VI.
Hi all
I created the VI with controls.
Every control has ACL.
Then I run VI.
How can I know about ACL when the VI was ran?
Respect
IskanderHi Iskander,
Thank you for getting back to me with an example project. Could you please answer some more of the questions I asked in the last post?
1) What steps did you follow to create your access control lists?
2) You say you have Access Rights for controls in your project. Could you please clarify what controls you're talking about, and how the access rights were applied to each control?
3) What will you be connecting the access rights to at the output? Will they be used as an input for another function, or are you going to wire them up to another VI?
Once I have a better understanding of how your application is set up and what you're trying to accomplish I can do more research into resolving your issue.
Thank you,

How can I read pdf files from LabVIEW with different versions of Acrobat reader?
How can I read pdf files from LabVIEW with different versions of Acrobat reader?
I have made a LabVIEW program where I have possibility to read a PDF document. When I made this LabVIEW program it was Acrobat Reader 5.0.5 that was installed on the PC. Lather when the Acrobat Reader was upgraded to version 6.0, there was an error when VI tries to launch the LabVIEW program. And Later again when we upgraded to Acrobat Reader 7.0.5 I must again do some changes and rebuild the EXE files again
It isn't so very big job to do the changes in one single LabVIEW program, but we have built a lot of LabVIEW programs so this take time to due changes every time vi update Acrobat Reader. (We have build EXE files.)
The job is to right click the ActiveX container and Click "Insert ActiveX Object", then I can brows the computer for the new version of acrobat Reader. After this I must rebuild all the "methods" in the Activex call to make the VI executable again.
Is there a way to build LabVIEW program so I don't have to do this job every time we update Acrobat Reader?
This LabVIEW program is written in LabVIEW 6.1, but I se the problem is the same in LabVIEW 8.2.

HOW CAN APPLY FREE GOOD 4 PRICING PROCEDURE?
TELL ME SIR HOW CAN APPY FREE GOOD 4 PRICING PROCEDURE?
Hi Pradeep
1.Run trans. VBN2 to first create master record for free goods as follows:
Enter following information in selection screen:
- Free goods type: NA00
- Sales org, distribution channel, customer # and execute.
Now in next screen create the record as follows:
- First select the exclusive button and verify that you are in exclusive view.
(that is if you want exclusive)
- Material#, Min qty - Say 34 cartons. (check in what units you want to manage)
From: 34 cartons
unit of measure:
Free goods: 12 Pcs
Unit of measure: Pcs
Calcualtion type: 1 or try the other options
Deliver control: Blank or any of the other options suitable to you.
Now save and exit.
Now run VA01 for 34 cartons and press enter. The system will automatically propose the free goods
item at no additional charge. Try higher order qtys and see if the free goods qty are scaling up.
If not adjust the calculation parameters in the master record screen
It should be transaction VBN1. Sorry for the error.
VBN2 is to change the record. VBN1 creates it.
If you want to give free goods to some of the customers than
1. create a customer group say 99 for FREE GOODS
In Free Goods Menu:
2. add a feild catalog for CUSTOMER GROUP
3. create a condition table (free goods) say 555 only for customer group
4. create a sequence say FREE with condition table 555
5. create a condition type say FREE with
6. maintain pricing procedure say ZFREE with condition type FREE
Now assign:
7. Active Free goods Determination or Assign with your sales organisation this procedure ZFREE
8. Create free goods determination with transaction code /nvbn1 for FREE with Key Csuomer Group
99 for exclusive
Give customer Group say 99 and from 34 to 34 free 12
Thanks

How can i load a VI from LABVIEW ver 6.0.1b3 to LABVIEW ver 6.1
How can i load a VI from LABVIEW ver 6.0.1b3 to LABVIEW ver 6.1......I want to load a vi but i'm getting this error:
LabVIEW load error code 9:VI version (6.1) is newer than LabVIEW version (6.0.1b3)
My LabVIEW ver is 6.1
Please help ......it's important
ThanksI am having similar issues with a *.exe from LV6.1. I have the runtime engine for 6.1 and recently upgraded to 8.2 from 7.1. I've never had 6.1 on my machine. I am able to install this executible and runtime engine on a machine with 7.1 and can run the *.exe fine.
I get a load error and am not sure why. I have had similar issues with old VI's that I have written in 7.1 executing on this machine w/ 8.2
any suggestions.

HT201364 How can i free up space on my startup disk to install OS X Mavericks?
How can i free up space on my start up disk to install the OS X Mavericks software?
For information about the Other category in the Storage display, see this support article.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Then reboot. That will temporarily free up some space. Do the same in other applications, such as Aperture, that have an internal Trash feature.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
If you're using Time Machine to back up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install ODS in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size with the largest at the top. It may take a few minutes for ODS to finish scanning your files.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal. -
How can i use activeX Control in labview?
how can i use activeX Control in labview?
please describe me step by step.
thanks.Well..that was quite helpful..but now I'm encountering certain problems. I've attached the VI I've made.
I don't need sound at the moment so I dropped it. (Although I tried to play it..but all I could hear was a very annoying sound.) Secondly I don't want to display any date or time..so i dropped that property too.
Now when I run this Vi...the webcam turns on, the screen of videocapx pops up..then the webcam light goes off..and another pop up appears saying..labview is not responding..and i have to close it reluctantly.
I haven't placed the stop capture property in this vi. i checked it by placing it too..but that doesn't work.
I would like to notify that my actual task is to acquire image and then compare it with another one already present on my pc. I want you to please help me out..solve my first query then I'll proceed with the latter part.

How can I reopen applications after hide
How can I reopen applications after hiding it using Command+H?
Usually we can find applications that are running in the dashboard after minimizing it, but I cannot find them after hide.Well, then, it is possible to set an option in the Dock to show hidden applications as transparent icons, but you need to use a utility such as iTweakx or MacPilot to enable it. If you have a normal Dock, of course all running applications have a little oval "light" under them.
True "background" applications are always invisible.
You could use the option of minimizing an application to the Dock so that it will always appear on the right side of the Dock. I use the option of double-clicking on a window's titlebar to hide the window/app onto the right side of the Dock. -

HT1338 How can i free up space on hd?
how can i free up space on my hd/
Begin by dragging your files to another drive. Then delete those files on your internal drive.
As soon as you have enough space freed up download and run OmniDisksweeper to find what's hogging your disk space. -

How can I free up space on my iphone without connecting to itunes?
How can I free up space on my iphone (by posibbly deleting some music) without connecting to my mac itunes? I'm travelling abroad for some time so can't access my itunes account on my mac at home and the iphone is full. I thought I'd left enought room for plenty of new apps, but alas no. So I need more room for more apps. We have my partners PC laptop with her itunes loaded if thats any use. I've deleted and backed up all my iphone photos already. Thanks.
Claiming that it can be done, but not telling him how is not all that helpful. We were dying for you to share the steps that he must take.
http://www.cultofmac.com/99990/ios-5-allows-users-to-delete-music-directly-from- iphoneipad/
The process is just like deleting an unwanted email in your inbox. Simply find the track(s) you don’t want on your iOS 5 device anymore, slide your finger over the track listing to the left or the right to reveal a hidden “delete” button, and then select “delete” and the track is gone. Unfortunately there’s no mass delete option, so those Backstreet Boys songs are gonna have to be deleted one at a time.
