Hi Mads,
This is really a good help, now I hope I can solve the problem.
Thanks a lot!

Hi Pawel,
This is the correct behaviour for the round to nearest Function.
This function Rounds the input to the nearest integer. If the value of
the input is midway between two integers (for example, 1.5 or 2.5),
the function returns the nearest EVEN integer.
Hope this helps,
Nick
Hi Pyi,
To answer your first question if you alter the vi properties (right
click on the front panel icon) and select window size there is a
scale all objects tick box at the bottom this shouls solve this
issue.The imaq question I believe is a separate package which you need
to
I am using Write to Digital Line.vi to set the state of a digital
line on my board, and then Read from Digital Line.vi to read the
state of a different line on the same port of my board. It seems like
when the READ executes, it does not maintain the state I set in the
WRITE. How can I fix this?
I would like to know if a tcp port is open or not. How can i do it ?
Hello, thank you for have answered to my question but probably I
haven't explain my problem very well.
My problem is this: after processing the signals obtained with the
accelerometers using the fft I have obtained a graph.I want to save it
in a file that I can use like I want but I am not able to
Only problem with this is that if the program actually does stop
working (hangs up somewhere), the indicator keeps animating and the
user just learns to hate the lying indicator ;) This is why I curse

I'd guess that the previous method using Search 1D Array would be
faster, if your array is large...

Any help?.
With your frequency spectrum, you have three elements, (f0, delta-f,
and an array of numbers for magnitudes of each frequency bin). You
can write this data to excel in the same way you write time domain
data. You can even re-cluster your FFT data as a time waveform, and
use the write waveform to

The usual reason this happens is because the Easy DIO VIs reconfigure
your board each time they run unless you wire in the iteration
terminal. Reconfiguring your board resets lines. Even if you do wire
in the iteration terminal, the first time an Easy DIO VI runs it
configures the whole port as
try using the end of line constant instead of the carriage return.
Hope this helps.
Just another thought on this though... you could put the frames of
your animation into a pict ring indicator and have your program
increment the indicator to animate the picture as the task progresses.
Agreed with your comments.
Something must show real progress somehow..

First, I am not using the Database Connectivity Toolkit. I have
written drivers that call Oracle's ADO (OLE DB) drivers directly. And
the LV interface is filtering things out. For example, the
documentation on the drivers says there's a method called Apppend
Chunk but it's not available from LV.

Your actual data are not accessible and the sub-VI is missing. If you
could re-post your VI with time data saved as default on your graph
that would be helpful.

I have used labview to pick up a call on a cell phone. It is easy as

Your proposal works when the VI is started by the ActiveX client, i.e.
an event is generated immediately.
However, once the VI runs, the value of the control connected to the

You've gone beyond my immediate expertise. I'm the owner of the
Database Connectivity Toolset and am only familiar with the generic
ADO interface. So do you call the Oracle drivers from LabVIEW ActiveX
functions or are you using the Call Library Node to go through their
drivers

This problem was related to the MS Forms 2.0 scrollbar. After talking

Oh I agree with that. Like it said, this is just the quick and dirty
way of doing it. You have to lock up the computer to stop the

real progress indicator is much better. Instead of just saying Please

It was meant to work that way so that you have a way to abort the
event if you feel like you made a mistake when clicking on the
control. Just keep your mouse in the proper area.
Stephen,
In order to generate two pulse trains on the two counters of your
6115, then you will need to provide a trigger to start both of these
counters simultaneously. The counters on the 6115 are controlled via
the DAQ-STC counter/timer chip.
In order to perform these operations you will need
I've downloaded the Multiple Selection Dialog Box program and it

Hello Jujian,
Thank you for contacting National Instruments.
The amount of your back log is system dependant. It depends on the
computer and the applications running on that computer. To set your
buffer size, simply look at your maximum scan backlog and add 100 to
prevent a buffer overflow

Right-click on the 'Files of Type' array and select 'Data Operations,'

You'll now not lose this on reopening the VI.

Hello Miro,

If these do not solve the problem,
The input range that the DAQ card uses is based on the range that you
specify in MAX for the virtual channels. MAX uses the actual
specified range to apply a set gain to the inputs so that it best
fills one of the available range configurations on the card.
If you refer to the user manual or

I have gotten good results using VI server technology and using call
by reference to get data.
I have never attempted to push the trasfer rates you are looking at
but I think it is worth a quick try.
The beauty of this approach (IMHO) is ZERO TCP DETAILS (sorry) to
code.
I am going to use hp33120A to generate a waveform. I also need to
control the impedance of it become High impedance.
Sound like you may need to add a sequence local to pass data to the second frame?

Thank you so much for your helpfulness. I'm so impressive for your

Thank you again.
Three different units are being measured simultaneously, which is why 3
boards are necessary (they don't all start or stop at the same time, but
they could all be on at the same time).
Why not use one board continuously acquiring data on 6 channels an 10MB/s
and just discard the data not needed
I have been interested in this thread - it is pretty normal for people
(managers/clients) who don't actually use LV or DAQ to ask for something

Then the questions when quoting may be:
Do I quote it straight up, even though it is kind of stupid (trying to
