Is There a way to programmatically extract global virtual channel info from max?

I have a group of DAQmx virtual global channels setup in MAX and I would like to be able to programmatically extract the physical channel information to be included with the data file. In the past I have been able to use traditional NI-DAQ channel utility vi's to accomplish this, but they only see traditional NI-DAQ virtual channels and not DAQmx virtual channels. Is there a group of vi's for extracting DAQmx virtual channel information? I'm using Labview 7.1 with a Windows XP OS.

Paul,
I can access basic properties using the approach you described, but do you know how to get the units from the global virtual channel? Say I had a general appliance for reading in load cells, and I wanted to have the axis labels in a graph show the units of whatever load cell had been selected.

You can use another iPhone (or iPad) to restore it too, or you can login to www.icloud.com (assumng you weer using iCloud) and export your contacts from there.

Is there a way of programmatically accessing fault/error/BIT information from the PXI-6723 during runtime?

In fact can you access fault information for all PXI cards? How do i detect that there is a fault with a board from within the software so i can report this to a higher level application?
Thanks
Martin

Hi Robert,
So in essence what you're saying is that if a component on the device fails there is no way to know this as long as the device is still communicating with the PC? It would appear that the Self Test function is a bit of a misnomer - it doesnt actually do what it says on the tin.
So which of the 2000 errors can actually be returned by this function call? I appreciate that there are a broad range of errors but I would like to know which one(s) can in reality be returned by this function. I need to somehow categorise the errors into whether or not the device is healthy so i can communicate this to our customers software (wo have no knowledge of internal NI error codes) so they can decide whether the board needs replacing. Of the 2000 error codes which of these could potentially relate to a hardware failure of some sort as opposed to a software configuration error.
I have found this thread which details some error codes on a NI 446X device (is there something like this for all errors on all devices?):
http://digital.ni.com/public.nsf/allkb/95328C2FAF9DA99A862576E200785C11?OpenDocument
Lastly where in the NI DAQ help references are the list of error codes and meanings as listed in NIDAQmx.h. For instance what does DAQmxErrorPALThreadControllerIsNotThreadCreator actually mean? I don't want to wait for the error to occur in my system before I get information on what it means - it would be useful to know and understand before I write the software what errors may occur on each device.
Thanks

Is there a way to disable plugins globally, but enable them on a per-site basis?

Is there a way in Firefox to globally disable plugins and allow only certain sites to run them (i.e., a whitelist)? I've tried working with CAPS, but it doesn't seem to be able to turn off <embed> or <object> tags, only certain aspects of JavaScript. I know about FlashBlock, but I've heard it's easy to circumvent and isn't meant for security. NoScript has this ability, and it's great for my own PC, but I'm looking for something more simple that I can use on the PCs of my friends and relatives.

No, not in the basic Firefox build, and I haven't seen an extension with those features that is simple enough for the "average user" to use.
Flashblock only blocks Flash, Shockwave, and Authorware. Plugins like Java, Silverlight, and other aren't blocked by Flashblock. There is one manual control extension for JavaScript, Java, Flash, and Silverlight - Quick Java - https://addons.mozilla.org/en-US/firefox/addon/1237/ - but there is no "whitelist", only toolbar /statusbar buttons to toggle those plugins on/off.
As you mentioned, NoScript has features to block specific plugins from running automatically, and also has a "whitelist" so those plugins will run automatically on "trusted" websites, but getting the NoScript "whitelist" set up is a continuing job. It can be a frustrating extension to use for even "above-average users".
I use NoScript on my Windows desktop PC's as it is intended to be used - allowing JavaScript per domain / website by "allowing" or "temporarily allowing", but on my Linux netbook ''(900MHz processor and only 1GB of RAM)'' I have it set to ''Allow Scripts Globally'', so I don't have to allow JavaScript for each domain on every website I visit. When I first got that netbook I ran for a few months without blocking anything, but after Firefox getting stalled by too many unnecessary plugin presentations I installed Flashblock. After a few weeks I realized that Flashblock wasn't blocking enough of the plugins that were causing problems, so I switched to NoScript with ''Allow Scripts Globally'' selected. IMO, Linux is much less of a target than Windows PC's are as far as exploits and Malware are concerned.

Is there a way to create a multiple event screen saver from iPhoto events?

Is there a way to create a multiple event screen saver from photos in iphoto? I can create a single event screen saver, but don't know if it is possible to create a screen saver with more than one event.

Drag the events you want into an album and have the screen saver run from the album.

Not if you set up very carefully what you want synced from your computer. Make sure you have not set things to sync automatically and manually choose the settings of what gets synced

Is there a way to view all favorites on one page from different albums?

I can't seem to figure out how to view all favorites at one time.
nothing (thus far) is shared.
paid membership to revel, also.

oops - apparently you can do this from the app,
but not from the web login view.

Is there another way to close apps other than deleting them from the multitask bar.....I have a small crack in the bottom of my screen and that part of the screen does not recognize the touch. :(

Is there another way to close apps other than deleting them from the multitask bar.....I have a small crack in the bottom of my screen and that part of the screen does not recognize the touch.

There's generally no reason to be closing them that way at all. The apps you see in the recents bar are just that, apps that you used recently. Most of them are doing absolutely nothing. The only apps that are really doing anything in the background are ones that play music and ones that are using location services. Just leave them be.
Best of luck.

I've copied my itunes library onto an external hard drive. Is there any way I can do this and delete songs from my PC without also deleting from the external drive? Already lost two songs!!!

I've copied my itunes library onto an external hard drive. Is there any way I can do this and delete songs from my PC without also deleting from the external drive? Already lost two songs!!! I just want a back up - using a work PC and don't want others accessing my songs. Hope someone can help. Thanks!

I see. To get a better idea of what is being stored where please download and run the script iTunesInfo which should output something like this:
I'm interested in the block of 4 results starting ITL location. If your profile name shows up somewhere replace it with <Name>. It is also worth checking under Edit > Preferences > Advanced to see where iTunes thinks your media is supposed to go. My script estimates the setting based on the location of the first media file it can actually find.

Use iTunes to backup files from your old ipod first then transfer to the new iPod. Please
follow the steps in How to transfer your backup from one iOS device to a new device. By the way, if you don't have the iTunes, you can use this iPhone transfer program. It help you to transfer sms and contacts from iPhone.

Is there any way to get the query used in discoverer from backend??

Hi All,

Is there any way to get the query used in discoverer from backend??
Thanks,
Sachin

Hi,
you can view the SQL from within the discoverer menu:
in desktop: View-> SQL Inspector
in Plus: Tools-> Show SQL
The SQL in the DB tables is encrypted so it's a problem getting it from there.
You can export the workbook into SQL but it is not working for every worksheet (subquery, inline pivot tables...)
you can create a batch file to export them all using the output of this script:
select null,null,'echo off'
from dual
union all
select distinct
qs.qs_doc_name Workbook_name,
qs.qs_doc_details Worksheet_Name,
'start /wait <path>\dis51usr.exe /connect '||'&p_user_name'||'/'||'&p_password'||'@'||'&p_env'||' /apps_user /apps_responsibility "&responsibility" /opendb '||
chr(34)||qs.qs_doc_name||chr(34)||' /sheet "'||qs.qs_doc_details||'"'||' /export SQL "C:\Export Discoverer SQL\'||qs.qs_doc_name||'-'||qs.qs_doc_details||'.sql" /batch'
from eul_us.eul5_qpp_stats qs
where qs.qs_doc_name is not null
--order by 1,2
union all
select null,null,'echo off'
from dual
union all
select null,null,'exit'

If you activated "Find My Mac" in iCloud before the loss, maybe. Otherwise no.
