How to read from two boards at the same time

I have two NI DAQ Boards, a PCI 6034E and a PCI 6025E I want to make one a master and one a slave and read from both at the same time. Do they need jumpers between them
from one board to the other or does the motherboard bus take care of that? I can find software to handle this but I can't find anything on the way the hardware should be configured, is there a cable I need between them?

Hi,
We have a couple of great tutorials on this:

How to make this two things at the same time ?

Hello
When my mouse is on a area, I need :
- to show a object (a rectangle inserted with the toolbar)
- to show a caption
I think it's not possible to do this two things at the same time when I use the rollover functions (Rollover caption or Rollover Image).
I would like to use a button, but the button works only if I click it, and not when I just pass my mouse on it.
Someone have an Idea?
I can't use Javascript.
Thanks

Rick is correct. You can use the Rollover Slidelet's rollover area to trigger an Advanced Action. You'll need to create this Advanced Action with two clauses. One to SHOW the caption, and the other to SHOW the rectangle.
Your alternative to the rollover slidelet is to use an Event Handler widget attached to the object that the mouse should roll over.
The Event Handler will detect when the mouse is over the object and trigger its own Success criteria. You can then use the widget's ON Success event to trigger the Advanced Action as mentioned above.
More information about using the Event Handler here: http://www.infosemantics.com.au/adobe-captivate-widgets/download-free-trial-widgets
An example of using it to do two different things on the same object can be found at this web page: http://www.infosemantics.com.au/adobe-captivate-advanced-elearning-tutorials/beat-adobe-ca ptivate-interactive-catch22
Trial versions of the widget can be downloaded from here: http://www.infosemantics.com.au/adobe-captivate-widgets/download-free-trial-widgets

How can I open two libraries at the same time on itunes?

Hey i need help on opening two libraries at the same time on itunes. I don't know if that is possible but need some advice if its possible. I already have several libaries but I need to compare labaries at times due to various users on my computer. Please help .

Not that I'm aware of. What exactly is that you want to achieve? There are tools for scanning media folders and adding any files not listed in the library, or deleting those that no longer exist. There are also ways to use one library for multiple users so that any tag update gets applied for everyone.

How can I start two Vi at the same time?

I have two Vi's, each of these Vi has a stop button. I want to start these two Vis at the same time. I also want to be able to stop the two Vis at the same time. What should I do? Thanks.

One way to start them is with an Invoke Node and the Run method. You can then stop them with the Set Control Value [Variant] method. When you use the Set Control Value [Variant], you just have to specify the name of the front panel control that stops the while loop. Older versions of LabVIEW only had the Set Control Value method in which you had to use the flatten to string function to pass the Type Descriptor and Flattened Data.

How to read from and write into the same file from multiple threads?

I need to read from and write into a same file multiple threads.
How can we do that without any data contamination.
Can u please provide coding for this type of task.
Thanks in advance.

Assuming you are using RandomAccessFile, you can use the locking functionality in the Java NIO library to lock sections of a file that you are reading/writing from each thread (or process).
If you can't use NIO, and all your threads are in the same application, you can create your own in-process locking mechanism that each thread uses prior to accessing the file. That would take some development, and the OS already has the capability, so using NIO is the best way to go if you can use JDK 1.4 or higher.

How can I use two ports in the same time?

My application need one pc use two ports the same time.But when I open one port and my systerm is running the other port can't be opened.
I use the frame API in VC++6.0.
My OS is win2000 server;
The functions I used are ncOpenObject();

Hi DickW
Thank you for your help!
I have tried the example.But the example shows how to connect one CAN network with two ports.
I want each port connect to the net can both read and write;
I want to apply the function like this:
1.config the port1 and port2
2,open port1 and port2
But after I open port1 or port2 the other port can't be opened;
After I open the second port it always returns negative.
In the codes I use CAN0 and CAN1 as the CAN objects.

How can I view two emails at the same time

Is it possible to view two mail messages at the same time. We are testing iPads at work and this is the biggest problem

You cannot view 2 emails at the same time on an iPad. This is not a supported feature.

[Bug] Writing to the same trace in Citadel from two Sources at the same time

Howdy
I am experiencing an issue and am looking to get some NI support:
I have two distributed applications that can write to a Citadel database at the same time.
And I am investigating the possibility of what would occur if both of them were writing to the same variable at the same time, with possibly the same timestamp data.
I did this in the attached VI by using the same timestamps with a constant for the data (either #1 or #2).
This generates an error, as expected, stating you cannot have two references open at the same time.
The data file, dumped from Citadel, contains 1000pts with all data from only one of the arrays (in this case #2) and everything looks fine:
However, what appears to be happening randomly tho, is that the same portion of code can also returns no error.
When the data is dumped from Citadel this file contains 2001pts - 1000pts from each array and one separator (or break) point:
You cannot write an older timestamp to Citadel without it throwing an error, but from further testing it seems you can write the same timestamp repeatably. So I am guessing what is happening above is race condition that is somehow allowing two references to be opened to Citadel which should throw an error but it does not and this is somehow allowing both sets of data to be written by both loops??
The data, IMO, is now corrupted.
Is being able to write to the same timestamp a desirable feature?
Or is this a known issue or a bug?
What about acquiring two references - bug?
Is there a workaround to protect the data from multiple distributed-application writes?
Cheers

The race condition of opening the refererence in two places at once should still apply to two different VIs running at the sametime.
Will a CAR be lodged for this?
Ben S wrote:
If you open up the code and save it as a .vit, you don't get any missing VIs. Only when you change the extension without the aid of LabVIEW.
No VI should have missing members by simply renaming its extension outside of LabVIEW???
I think there is an issue with the VI.
Can you replicate the following and verify what I am seeing?
Attached is a Project with Main VI (contains a call to the Open Trace.vi polymorphic only), a Class and a Build Spec
If you Build the spec with the Main VI outside of the Class it works
If you place the VI in the Class, save then Build, the Spec fails with the error:

Save the VI
Close the VI
Open the VI - the Open Trace.vi polymorphic is "missing"

How do i sweep two voltage at the same time by using for loop ?

Hello, Can anyone help me on this topic ?
My problem is to sweep Vds and Vgs as same time vs Id in MOSFET by using for loop. I also use the Agilent power supply source. Let me tell a litle bit about what i'm doing. For different value of Vds, i will get Vgs vs Id curve. (The x axis is Vgs, the y-axis is Id).
I started to create two for-loop, the inner to sweep Vgs, and the outer one to sweep Vds. My problem is don't know how to connect all the wire in the for loop.
In the for loop i saw N, i icon. Suppose I have the two variable for Vgs such as Vgs start and Vgs_stop. Should the Vgs_start( or Vgs_stop) be connected to N or leave it in the for_loop ?
for example: I want to sweep Vgs from 0(for Vgs_start) to 5(Vgs_strop) V, and the step increment is .5V how do i connect these variables in the for loop ?
Thank you for your time
Ti Nguyen

It is easier to use a while loop. Dennis beat me to the punch. Here is my solution:
You can remove the flat sequence structure if you use Error In and Error Out to ensure the execution flow will occur in the proper order. Be sure to include the delay time in the loop so that your vi doesn't hog all the CPU time.

How can I compare two collections at the same time? (View two grid views)

I have two collections containing some of the same images. (My Nikon D70 did not put an end-of-file on some images. I recovered them into a different collection.) Now I want to display both collections side-by-side in grid view. I will select those images in the "recovered" collection that correspond to the bad images in the "main" collection, add the ratings etc, and move just these to another collection.
It is extremely frustrating to have to bounce back and forth between collections, remembering each image one by one and selecting it in the "recovered" collection. (The image names are not preserved in the "recovered" collection -- I have to go by what the image looks like.)
LightRoom allows me to compare photos in the compare view. I want to compare collections in two grid views.

CaptureTheLight,
you have ran into a situation when you have to compare two sets of images and now you're wondering how come Lightroom doesn't have such "obviously necessary" functionality? But you have to admit it, this is not such a common situation in a photographer's workflow recovers broken files and tries to compare them against themselves. I think it's a pretty specific feature you need. Still, Lightroom has enough powerful tools for editing and sorting images.
For example...
You could just put them all - "main" and "recovered" - into a single collection or into the Quick Collection. Label the entire "recovered" collection with, say, red and sort by capture time. Now you'll have everything side by side, ordered chronologically. The "recovered" images will stay next to the "main" images since their capture time will be the same, and they will also stand out since they have the red label.
Make the thumbnails bigger and set up the grid view so it tints the thumbnail cell are tinted with the label color. Now, you can go quickly through them visually checking labeled vs unlabeled.

Singletons running on two servers at the same time

Hello,
          we faced one interesting situation with our application, running on clustered BEA Weblogic 9.2. We implemented some Singletons (ie. Singleton Service in a Weblogic cluster) and they are running fine. Most of the time.
          Common scenarios: cluster is started -> the singletons run on one server; the server is brought down -> the singletons are started on the second server.
          However, we had recently two situations where the Singletons started on both servers! Here they are:
          1) We use Database Migration Basis and we have a dedicated table for Weblogic to capture current state of the singletons. Due to the fact that database (Oracle RAC) was partially available one of the Managed Server could not get the lease and probably assumed that no singleton is running, therefore started the singletons locally.
          2) Network outage: we had several minutes where none of our servers could communicate between them (neither between SASU MS nor with the database). Consequence: each MS decided to start the singleton locally (after some time, which I assume is the waiting time). Once the network came back the servers could communicate again but the duplicate singletons are not deactivate, so they are running in parallel.
          Anyone experienced the same or similar issues? How to prevent the above? Is the Consensus Migration Basis a better choice? (I think yes for #1 but not for situation #2).
          Any helpful answer is appreciated.
          Thank you, best regards,
          Remus.

In general its not a good idea. Running PSConfig will try to establish a lock on the configuration database. Doing that from two servers at the same time may cause the update to fail.
