Multithread Voltage/Current Check using 2sets of DMM

Hi..
I need some fresh idea on how to solve my problems. I've been using Labview for about 3years now.
Currently I'm trying to modify my current VI for multithread check. Last time my VI can read from only one Digital Multimeter (DMM) and now i want it to be able to read from 2 sets of DMM so that the process can run in parallel & execution become faster. Have any experts out there tried this method before. Some suggest me to put the block diagram in parallel so that the data can be execute at the same time. Is this true?
I've read through all the thread but can't found the answer I'm looking for. There are suggestions from others to use TestStand but I'm not familiar on how to use them. Plus I don't want to make big modifications on my current hardware designs.
Attached together is sample of my current VI using only 1DMM. I welcome all to give any suggestion and opinion for easy way to perform multithread check for my case. I'm using Labview 8.5 so please let me know if you can't open them.
Thanks and Regards,

To Kate & Dennis,
Sorry for the trouble. I forgot to remove the password. You may unlock using this password "mepowerrr'. Can you guys give me suggestion based on my current block diagram.
Btw, I connect to DMM using USB and GPIB through VISA. I control the DMM by creating an instrument file within my application. The instrument file is different for each DMM. Try to make my program suitable for all type of DMM (Agilent, Tectronics & Fluke). Now I just worried thinking if its possible to do multithread check on my application.
Is there an easy to do this?

If it's showing the connect to iTunes screen then you will need to do that.
But Apple don't provide any method to update the first gen iPad to iOS 5 (nor do they support downgrading the iOS version).

I am trying to configure my SCXI-1540 card for excitation voltage and frequency using MAX - but it is not giving me that option when I click on the card and then properties, am I looking in the wrong place?

I am trying to configure my SCXI-1540 w/1315 card for excitation voltage and frequency using MAX - but it is not giving me that option when I click on the card and then properties, am I looking in the wrong place?
I have LabVIEW Express 7.0 Professional - SCXI-1000 Chassiss - along with SCXI-1112, and SCXI 1520/1314 - cable to the PCI-6052E is attached to the 1520 card.
MAX says it recognizes all the cards in the chassiss.

Jeremy, Thanks for the reply.
I tried to set up the system as DAQmx.
I had MAX auto-detect the set-up - and it recognized all the cards - but did not select the 1315 accessory on the 1540 card - I had to do that manually - but in the configuration section I would select the accessory and it would deselect itself. I had to get out of the set-up and then right click on the 1540 card and click on the "Accessories" tab and select the 1315 terminal block that way.
It didn't seem right that the system should behave that way, but I pressed onward.
I then tried to create a new DAQmx Task
When I create new DAQmx task and then click on Analog Input no "Position" Tab appears for me to select, all I get are:
Analog>>Voltage
Analog>>Temperature
Ana
log>>Strain
Analog>>Current
Analog>>Resistance
Analog>>Frequency
Analog>>Custom Voltage with Excitation
Do you think there might be something wrong with either my hardware or perhaps my configuration that is not allowing it to recognize the 1540/1315 in DAQmx?
I had included the system report of what programs I am using, etc. as attached file nireport.txt
After the DAQmx did not work I tried installing everything as Traditional DAQ and it did let me set-up the 1540 Card with Excitation Voltage and Frequency and gain - I then went in to the VI that I had built and tried to use the Express DAQ Assisant to read the channel that I am connected to on the 1315/1540 - when I try to use DAQ Assistant it gives me an error saying that "Device not available in NI-DAQmx. It is possible that the device is being use by traditional NI-DAQ"
Which I guess it is since both configurations are now set-up in MAX.
I would PREFER to use the DAQmx set-up, but I am confused as to WHY it won
't come up with
Analog input>>POSITION>>LVDT
When I try to create a new DAQmx task.
Thanks for the help so far! As you can probably tell I am new at this.

Error: "Airport Expess" is currently being used by someone else...

Error : "Airport Expess" is currently being used by someone else. Please select another device from the menu at the bottom of the iTunes window.
Please help me with this issue.
I have iTunes constantly throwing this error whenever I try to stream to my AirPort Express.
it is frustrating not getting any answer from Apple.
They just ignore those of us having the same problem
Thanks
Luis

Replaying to myself, I found what was causing the problem.
I have an Ubuntu machine and I was making some test to stream to Airport Express from Ubuntu.
Under Pulseaudio preferneces I had checked "Make discoverable Apple Airtunes sound devices available locally" for tests some months ago.
Unchecking it solves the problem.

I cannot eject external HD: "the volume is currently in use". Why?

I have a Maxtor 500GB HD attached via USB to my laptop. Quite often, when I want to detach it I get the message: "The Volume could not be ejected because it is currently in use". However, I am NOT aware of ANY active application that is still using the HD.
Any help would greatly be appreciated. Thanks in advance.
Veit (from Austria)

Although this might be wise, it cannot be considered a solution valuable to an Austrian.
Would Arnie wait for his drive to disconnect? "Moo-f it - or Y'll crush you!"
Certainly not, in a hero's life time can be of extreme value.
Coincidentally I'm Austrian too and often face the same problem.
I just make sure that no major piece of software (check dock) is running, then I start counting down 10...9...and pull the plug on "8", not very fair but the right thing to do given the circumstances. So far I haven't lost any data, even better the problem has dissappeared, obviously the computer now shows some respect, down to the tiniest hard drive hogging little thread.
Disclaimer: Take this advice only if you truly have the guts standing up against your operating system and are willing to face the consequences...don't let me see that twitch in your eye when them GB's throw you a final "Hasta la vista".

"Connections currently in use" negative???

WL 4.5.1 sp7, Solaris 2.6, Oracle 8i
We're have multiple connection pools set up on wl, and are seeing very slow
response on one particular pool. Upon inspection of the WL console, we see
that the connections currently in use is '-5'! Is this a console bug, or is
WL somehow catching more returned connections than checked-out connections?
Gene

This is the case on slow connection pools in WLS 4.5.1. It is fixed in SP13.

Hi Mike,
Here is the modified service pack doc which includes the reference to Issue

This fix made it to source but for some reason did not get documented.
So this fix for sure is in service pack 13.
hope this is what you are looking for.

It's neither of those, it is probably a counting bug in that server'sversion
of the pool.

Net_rim_bb_appworld is currently in use

Some time ago I tried to install bb app world to my BB8900. The installation failed because I don't have data connection purchased and WiFi doesn't work with this app onmy phone. I just tried to delete it from my BB8900 and I got the warning: "net_rim_bb_appworld is currently in use. Are you sure you want to delete it?" I'm sure I'm not using it right now, even more - it can't be used because of the limitations implemented by RIM. What's going on? Is my BB8900 using some modules from this app and it can be safely removed or there is something that I'm not aware about?

Check the below location. If it's installed in your device then it must be listed there. Options -> Advanced Options -> Applications -> BlackBerry App World.
If It's listed there then highlight BlackBerry App World and click Menu -> Delete.

BW variable: Inconsistent in loading. please check use of deleted objects

Hi Experts,
I encountered an error and can not solve it following OSS note.
When I create a variable in query definition for an infoobject, it prompts an error dialog 'Inconsistent in loading. please check use of deleted objects'.
I checked the OSS notes 792779, there is a such description:
The variable existing in the table RSZGLOBV, but not existing in the tables RSZELTDIR or RSZCOMPDIR have inconsistent definition. These situation may return 2 different error messages. When a variable is missing in RSZELTDIR table (or in both together), an attempt to expand a list of variable under a corresponding InfoProvider or a list of text/formula variables will return a message 'Inconsistency in loading...'. All variables which are created for corresponding InfoProvider, text/formula variable are not available. When a variable is missing in the RSZCOMPDIR table only the error message is 'Missing UID XXXXXX... in RSZCOMPDIR! You may continue to work, but this component is not loaded' in Query Designer
But I checked these tables RSZGLOBV and RSZELTDIR and RSZCOMPDIR. I can find a variable for this infoobject, such as TC_SREG, in these tables. That is, this variable should be availbale in the query definition.
I don't know why.
My sap bw is 3.1, without the program 'ANALYZE_RSZ_TABLES'.
Many thanks for you help.

Hi,
While installing business content make grouping as Data Flow before and collection mode as 'Automatic'. Then expand the Tree in the tree you can see Info Object Catalogue. All installed and activated object will be in green (Active Mode). those will be normally unchecked to install anyway cross check and if found anything check deselect them. Go for Simulation Installation to identify unforeseen errors. Install the same and activate entire data-flow.
Hope your issue will be resolve
Thanks

CRM ATP Checking using R/3 & Immediate Delivery for Sales Order Type in R/3

We use CRM 4.0 and R/3 6.4.
I've configured CRM to do ATP Checking using R/3. The ATP Checking works fine if I change the Sales Order Type in R/3 to NOT create a delivery immediately.
I'm trying to find out if the combination of turning on CRM ATP using R/3 and Create Delivery Immediately for a Sales Order in R/3 are supposed to work properly together.
If anyone knows and or has this working, I'd like to know.
Thanks.
Donna

Hi ,
I am working with R/3 and I have the same problem.
Complete delivery is flowing down from the customer master for all order.
And then we have items on order which have different shipping point.
They all fail in background delivery and give the error ' customer requested complete delivery'.
Is there anyway to override this?
Any help will be really appreciated.
