How to implement an ethernet without TCP or UDP communication?
I know there are blocks to transmit/receive data via the Protocol TCP or UDP in Labview,.
but I need to pass data between one compactRIO and another device that is not NEITHER device.
They communicate via Ethernet, BUT this unit has its own Protocol (TCP or UDP),
So just me LabVIEW to transmit raw data via Ethernet without any header (for example TCP or UDP, etc.) because I will deal with it by myself,.
What is the best work in Labview can I use for this?
Thank you!!
None! You must call directly into the OS API Jack for a raw configuration network socket, and then use read() and write() on it. Note that raw sockets are all modern operating systems preferred Office of resources which can only be opened by a process granting access rights. On Windows, it is reserved for processes with administrator rights. In Linux, there are just special access that must be given to a process for this.
Under cRIO this right of access is probably not a problem, but you may encounter problems that raw sockets are only partially taken in charge there.

How can you unlock or implement an iPhone without a sim card & apple computer laptop?
You need a SIM card, and if the phone is locked to a carrier, the SIM card must be that carrier. It doesn't have to be an active SIM; It may be one that has been disabled. You don't need a laptop Apple; You can activate Windows 7 or later, or Mac OS X 10.7 or higher.

How to implement the reading of data from a matte file on a cRIO?
Hi all!
I'm still not sure, it is plausible, but I'll ask rather before you begin complicating. So far, I found no useful information on reading in the data to a device of RT from a file (type of a simulation test - data is simulated).
I have the MatLab plugin that allows the storage of data read a MAT file, which has a number of columns that represent the different signals and lines representing the samples at a time (depending on the time of the sample - sample every time has its own line of signal data).
I have no idea how to implement this at cRIO.
The idea is:
I have some algorithms running on the controller of RIO in a timed loop. As the entries of these algorithms I need to access each of the values of columns in the row, which is the time of the sample (sort of a time series - without written actual times).
I am fairly new to RT and LV development, so any help would be appreciated.
Thank you
Luka
Dear Luka!
I think the reading of all the samples in a single channel is exactly what you need here, because reading the files may take some time and is not deterministic, so it is best to read all the data in memory (or if this is not feasible due to problems of size, fairly large pieces may be sufficient). The table read can be provided and then in the loop simulating outings, something like this:
I used here separate channels so it's more graphic, but you can build all the channels in a 2D array and array index corresponding to the samples fom 1 who. You can also use for loops with indexing as tunnels are setup and then you won't need the index functions and the number of iterations is also set automatically, but you have to take care of synchronization settings.

How do I know if I have more than one of the same song in my library, and if I do how do I remove it without deleting both copies?
Hello
Duplicates would be revealed by the observation. If found you are probably followed the same
record twice.Add items to the Windows Media Player library - see the monitoring records - and delete a folder
controlled by the player.

If you think there is duplicate in separate folders files:
Here are a few utilities to help, be sure to remove duplicates once and good
folder. If If doubt copy the file to another folder, delete and then check WMP.Here are several free utilities and they have all their benefits and their methods.

and by the size of the file. SearchMyFiles allows you to make a very specific search that cannot be
done with Windows search.

How to implement backup-lamw script (ghettoVCBni.sh)?
Who can help me (to understand how) to implement the (page ghettoVCBni.sh) lamw backup script? Even after a lot of Googl'ing I don't know how to do this (.. newbie...). I'm currently under ESXi with 2 data warehouses the and would like to backup computer virtual from the first to the second. I guess I ran the script on the ESXi host computer but can not find a way to the place to go. I would really appreciate if someone will write a howto (small).
Thanks in advance, Edmond
1) you must enable access to the ESXi console.
Follow these instructions to do so: http://www.vm-help.com/esx/esx3i/ESXi_enable_SSH.php
2) option: if you mainly in Windows (if no, go to 3 ), open ghettoVCBni.sh in Notepad (it is asuming you have already downloaded the script of http://communities.vmware.com/docs/DOC-8760) and change:
VM_BACKUP_VOLUME = / vmfs/volumes/kevin-test-nfs-storage
in order to take into account any data store that you want to store your backups in. In your case, it would be the name of your second local data store. The data MUST have store a vmfs/volumes/above IT. Another option, you should look at is the previous backups how you want to keep for each virtual machine. This can be changed on the line:
VM_BACKUP_ROTATION_COUNT = 3
WARNING: DO NOT PRESS RETURN AFTER ALL AS notebook of LINES to the INTERIOR THAT IT CAN break INTO THE SCRIPT.
3) SCP the file ghettoVCBni.sh on the ESXi server. You can use WinSCP (user name is root, password is any password you gave ESXi) to do if you are running Windows, use something else, the *nix scp command. (for example from the source running: scp ghettoVCBni.sh [email protected]: )
4) SSH into the ESXi server using "putty" or something physically go (or use Digital KVM or other) to the ESXi console itself and log in as root.
5) make a file on the ESXi server that lists the virtual machines that you want to back up.
There are two simple ways to do so:
Has) create the file backup_vms inside the ESXi console
If you know how to use a * nix like vi text editing tool, then use it to create a text file that has all the display names for the virtual machines that you want to back up. Don't forget that there is a new line for the display name for each virtual machine.
If you don't know how to use a * nix text editing tools, the easiest (though tedious ) to do this inside the ESXi console is:
VM1 echo > backup_vms
VM2 echo > > backup_vms
VM3 echo > > backup_vms
To check your work, run: cat backup_vms
the output should look like:
~ # cat backup_vms
VM1
VM2
VM3
~ #
If it doesn't, run: rm backup_vms and start over (so note the tedious ). Someone chime if there is a way to do this without rm'ing or edit with vi.
B) create the backup_vms file it on a separate system and the SCP in the ESXi server. You must be careful, however, not use not Notepad because after each return, he will add in ^ M (where the warning at the top). It's bad. Again, you can check your work by using the cat backup_vms inside the ESXi console (after you scp it exceeds of course) to make sure there are not the weird characters.
Don't forget, the virtual machines inside the backup_vms of the file MUST be saved on the host of ESXi (i.e. existing in the inventory of the ESXi host in vi-client). In addition, it would be easier to have the ghettoVCBni.sh and backup_vms file to be in the same directory. For this document, this is assuming that you are in /. To make sure you're there, use pwd. To get there use: cd /
5) if you follow the optional step 2 then edit the ghettoVCBni.sh script using a text inside the ESXi console editor and change:
VM_BACKUP_VOLUME = / vmfs/volumes/kevin-test-nfs-storage
in order to take into account any data store that you want to store your backups in. In your case, it would be the name of your second local data store. The data MUST have store a vmfs/volumes/above IT. Another option, you should look at is the previous backups how you want to keep for each virtual machine.
This can be changed on the line:
VM_BACKUP_ROTATION_COUNT = 3
6) change permissions on script to allow execution: chmod + x ghettoVCBni.sh
7) run the script. In the case of this document: ghettoVCBni.sh backup_vms
8) sit and wait or go do something else.
These instructions also apply to the ESX ( under step 1 ). Oh yes, this script can be run on virtual machines (power) live and you don't need any additional trick to run it.
Nice day

I got an iphone 4 to a friend in the Canada. I want to use it here in the Philippines as a regular iPad reserved for wifi, how can I use it without sim card? It does not pass the activation page. Help please?
You can activate it without a SIM card. If it is locked, it takes a SIM card by the carrier, for it is locked. The SIM card should not be linked to an active line of service, but it must be present to activate it.
