Can formula node take string input and output string?

I am wondering if the formula node can take string input variable and output string variable after calculation. otherwise I have to output integers and then use case structure to select different output strings, that is kind of redundant in coding.

If you are just trying to read lines that have mixed formatting, you don't need any script nodes.
Can you attach a tpyical flne and a description of the desired read operation so we have a better idea what you are trying to do? Do all lines have the same overall format?

XiFi and Audigy Take Over Input and Output from Bluetooth Head

I am having trouble with my bluetooth headset when making phone calls in any VoIP application (Skype, Yahoo!). I usually use the headset as the input and output for my VoIP bits so I can move away from my desk, etc... First, it worked under XP with my Audigy no problem. I bought a XiFi and installed the latest drivers and it began stealing my audio. Oddly, it does not do it until the call connection is made (so I hear the ringing in the BT headset and once the call is answered the system reverts to the mic, a Logitech USB, and main speakers, directly plugged to the soundcard).
I decided to put my audigy back in, because I was planning on upgrading to Vista and thought the XiFi may be bad. I did a fresh Vista install with the Audigy and everything worked (i.e. audio for phone calls stayed in my BT headset). I then upgraded from the Microsoft drivers to Creative?s Vista drivers and the problem then happened with the Audigy as well.
This leads me to believe that some sort of regression happened in the latest drivers. Everything else works great, games, movies, etc? but this is a show stopper because I want to use my bluetooth headset. I tried to downgrade to the Microsoft drivers but the card would no longer work. I have tried a driver install only, then added the software, removed that and did a full install. This is with BETA drivers on Vista, but the problem existed in XP as well which were not BETA drivers AFAIK. I have updated to the latest Bluetooth drivers as well with no luck.
I have confirmed this on two of my PCs and a friend of mine is having the same problem (XP, XiFi) so he went and bought a Skype phone which works correctly.
Thanks in advance

I have on;y one audio port can i use it for input and output at the same time?

i have the new macbook pro 13 in and i want to connect aguitar as input and output on an amp but i have only one audio port

You can't use the jack as an input and output simultaneously. The solution is to look for a USB or Firewire interface to get your guitar sound into the computer.

How can I get my audio input and output devices back? I have no sound and cannot see any of the devices in Audio MIDI Setup..??

Hi, I tried to set up a new output audio device on my mac that would have multiple outputs (iBox Twist speaker and my internal speaker) but when I went to click onto one of the iBox Twist (there were 2 options available: iBox Twist and iBox Twist Stereo), Audio MIDI Setup crashed and when I finally got that back open, I found that there were no audio input or output devices to be found. My sound is working, as when I turn on my iMac, the starting sound still plays, however the volume control in the menu bar is no longer a black colour, but grey and when I try to change the sound on my keyboard it does not change. This already happened to me once, and after 3 hours I managed to fix it very simply (switching off Mac, unplugging power cord, leaving for 15 seconds, plug power cord back in and switch Mac back on, holding Alt, Cmd, P and R keys until you hear the Starting Up sound twice) however this same technique that fixed it once before is not working this time and I am still stuck without sound. I have tried Repair Permissions, rebooting in Safe Mode, Hardware Test and checking for Software Updates. Has anyone else had this problem and managed to fix it?
Thanks in advance for any help anyone can give me!

In case anyone has had the same problem as me, I have just managed to fix this by doing the following:
Switch off Mac
Switch back on in Safe Mode (Hit power button, then hold Shift key until a loading bar appears at the bottom of the screen).
Switch off Mac again
Remove power cord and wait 15 seconds
Plug power cord back in and hold down the keys alt, cmd, p, r all at the same time until you hear Starting chime for a second time and hopefully your audio will back.

Binding input and Output node elements

Hi all,
Binding Input and Output nodes of a model node.
Most of the time, we create a object of the input model node and then,
bind that object with wdContext.
Do we need to bind output node objects too in RFC Models?
Regards
Neha Singh

Hi Neha,
There is no need to create/bind the model node. you can execute a bapi using classes.
To execute a bapi, you should do the following things.
1. Import the RFC and create the model.
2. Create an object of the input class of the bapi
e.g. :
Zbapi_Test_Input commision_Input = new Zbapi_Testn_Input();
3. Set the input
commision_Input.setSpart(division);
4. execute the bapi
commision_Input.execute();
5. Disconnect the model
commision_Input.modelInstance().disconnectIfAlive();
6. Get the output. Create an object for output class
Zbapi_Test_Output output = commision_Input.getOutput();
String commission = output.getCommision();
Hope this helps you.

Can you perform simultaneous timed digital input and output using a PCI-6120?

Is it possible to do simultaneous timed digital input and output using a PCI-6120? It seems that timed digital operations require using the group read/write commands, which utilize an entire port. Since the PCI-6120 has only 1 digital I/O port, I would like to be able to use 2 lines as outputs and 1 line as input, and do both in a deterministic fashion. i.e. create a digital signal with known pulse widths and read an input line at a known time after the outputs were set. Is this possible to do with only one digital I/O port?

Hello,
This can be done in LabVIEW. There is actually an example that installs with NI-DAQ.
Below is a link to a Knowledge Base that explains how to find the correlated digital I/O examples.
http://digital.ni.com/public.nsf/websearch/B849664604EB34B886256D12005B5520?OpenDocument
Just take a look at the example titled �Continuous CDIO with external clock (E).vi�

How can I use a different driver for audio input and output?

I did a search of course, and came up with something about an aggregate. I have no idea what this is, how to do it, or if it would even work for me.
What I am trying to do is:
1) Record into Logic Express using my Tascam US-122.
2) Have playback come out of my computer sound system, not the Tascam.
If I go over to the Audio setup window, I can only record when the driver is set to Tascam US-122. Likewise, I can only listen to sound when my Built-In Audio is selected. It gets rather annoying going between the two.
So, would this aggregate thing solve my problem? If so, how do I do it? Thanks for any help!
-allen

Yes it should do what you want.
Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.

How can I make Apple Earphones be the Input and Output for Audio

I have some older headphones and they aren't compatible with a Mid 2010 (Intel Core i3) 21.5 Inch iMac
Is there some way to make Apple Earphones be the Input and Output for Audio in the iMac
This is a problem for me personally as when I am talking to someone on Skype the iMac picks up the In-built Microphone audio, and yes the headphones I'm using do work straight from the iMac as audio output
Any help is appreciated

you can connect the headset to something like this
http://www.ebay.com/itm/NEW-MaelineA-3-5mm-Female-to-2-Male-Gold-Plated-Headphon e-Mic-Audio-Y-Splitter-/381100440348
and then connect the mic to the input and the headset to the headset port

Can't restart our input and output frs

Hi,
last month we used our AT BOXI system to help restore a folder's worth of reports that an unfortunate user had deleted in production. In the course of the restore the AT BOXI CMS and input and output frs were pointed at the restored databases.
I've now tried to repoint the CMS and frs's back to the original databases and though the CMS restarts ok the frs's refuse to restart.
The shared drive with the frs on it was 'unshared' for a while according to our server guy who helped with the restore but he says he's put it back now just as it was (though I believe the old name was atboxifrs and it's now ATboxifrs). He also says all the access rights to the share are the same.
What could be preventing the frs from restarting?
We have BOXIr2 SP4 on a Windows server.
thanks

How do I create an xControl with multiple inputs and outputs?

Hello,
i am trying to write a new Xcontrol Element. In the data model I can create data types using the cluster to create compound types, eg an int and an int array. But how do I create an xcontrol which has multiple data inputs and outputs?
Kind Regards

Limping_Twerp wrote:
Alright: I see: An xcontrol is either an input OR an output. How do I achieve an output? Secondly: So you are saying the only Elements that can have multiple inputs and outputs are VIs?
Can you take a few steps back and explain what you are actually trying to do. SubVIs and Xcontrols have nothing in common and it is not clear why you even try to compare them side by side (e.g. in terms of the number of connectors).
Your questions about input or output tell us that you seems to have some misconceptions about xcontrols. Xcontrols are like regular controls, except they have some built-in intelligence that you can program. Most front panel object can be either controls or indicators and the same is true for Xcontrol. You create an Xcontrol, and after placing it on the front panel you can decide if it should be a control (where the code reads the value) or an indicator (were the code writes values to it). When you define the xcontrol facade, you also need to program how the visuals change if it is changed from control to indicator or vice versa.
As a first step, you should opend the example finder and look at some xcontrol examples.
Again, what are you actually trying to do?

Multiple inputs and outputs using DAQmx VIs

Hello,
I am fairly new with the LabView programming language. I have a few training books that I have been reading, and I have been following online tutorials and reading the forums. However, I have come to a problem where I don’t see a clear solution. I am using LabView 2009 (9.0f3) and DAQmx VIs.
I am using a NI 9172 chassis PLC, with two 9201 AI cards, 9217 AI RTD card, 9472 DO card, 9263 AO card, and two 9237 AI Bridge cards.
I am reading eight analog inputs with the 9201 cards, two analog RTD inputs with the 9217 card, three digital outputs with the 9472 card, three analog outputs with the 9263, and eight analog inputs with the 9237 cards.
I wrote a simple program to test one digital output task, two of the analog output tasks, and a single analog input task. I put all of them in the same while loop, and it worked perfectly. However, when I add analog input tasks to the same loop, I get an error 200022. So I tested each sensor individually by changing the channel before each run. I searched error 200022 and found that this is because I cannot start another analog input task until the previous one ends. With this said, I don’t know how to acquire an analog voltage in the same task as an analog RTD voltage. Both inputs take different constants in the start task DAQmx icon.
Attached is my test program. It is titled “Test All”. This is the program I used to test the various sensors. I tested the input sensors one at a time, and it worked fine. A few tasks are written just to test functionality, and will be added to later. The data is only displayed on the screen. I will add triggers and data write to disk functions later. This program works now, but if I add more analog inputs, it will generate the 200022 error.
Can someone show me how to correctly write the code for multiple inputs and outputs using DAQmx? All training materials and tutorials I can find all show a single input or single output, not multiples of each. Thanks for looking.

Hi RandyC,
The Knowledge Base article Using Different Types of DAQmx Global Channels in the Same Task goes into a little more depth of what Bryan is talking about, and it also includes some example code to help show what to do.
Hope that helps,

Simple input and output in a loop

I'm trying to get some user input in a loop. This is a simplification.
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        for (int i = 0; i < 3; i++) {
            System.out.println("Enter a string:");
            String myString = input.nextLine();
            System.out.println("output: " + myString);
}In NetBeans, it usually runs fine for a few loops, but eventually (running the program 5 times or so) I get output like this:
run:
Enter a string:
1
output: 1
Enter a string:
output: 2
Enter a string:
2
3
output: 3
BUILD SUCCESSFUL (total time: 9 seconds)It starts writing the prompt before the output and gets all jumbled. The problem is worse if I have more input and output statments in the loop. I thought it might just be a timing issue, but it doesn't matter how fast or slow I enter the information. After a few successive runs, the output always gets out of order. How can I keep in line?

hi!
why dont you try using printf it will give you a better formating capasities.
it work like this.
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        for (int i = 0; i < 3; i++) {
            System.out.println("Enter a string:");
            String myString = input.nextLine();
            System.out.printf("output: %s \n" , myString ); // the %s is the place the string will apear
                                                                                   //and the \n is a escape caracter that creates a new line.
}if you need more help with printf read this:

Input and output on same device, producer/consumer structure

Hello interested people,
I have a question about using the same device for both digital inputs
and outputs. I have written a simple program of one while loop
that continuously polls the device, processes, and requests. I
have addressed the device using two DAQmx Asst. and I have attached
them with their error in/out cluster terminals to provide data flow and
eliminate the chance of addressing the devices at the same time (which
produces an error). Now I want to change this program structure
to a producer/consumer loop foundation with state machine.
In this design, I will have the DI in the producer loop and the DO in
the consumer loop, under one of the states. I can't simply
connect the error in/out ports in this configuration, so my question is
how to avoid the error caused by addressing the same device
simultaneously with two different tasks (input and output)? I
have attached two VI's, the "One Loop" vi is the original configuration
(simplified), and the Producer-Consumer vi is a NONSENSICAL program
that simply represents the desired configuration. (I don't need
any comments on the programming of this vi, it is only an example for
illustration of the problem).
I am thinking about bundling the input data and the error cluster, both
from the PXI 6528 DI, into one cluster, queueing that up, and
unbundling the de-queued elements for some kind of data flow between
the producer loop and the "Request" state of the consumer loop.
Is this the right approach, or am I barking up the wrong tree?
Thanks

Hello,
It sounds to me like you really have two modes:
1. user interface actions determine execution
2. user interface is locked, and execution is automated.
I think it would make sense to use the producer consumer for an architecture. Basically you would do the following:
1. program the producer to handle the user interface as you normally would.
2. provide one additional event case in the producer which would be your "automated handling" case. In that case, you could put a state machine which could run until whatever conditions were met to put your program back in "user interface mode".
Keep in mind that you can use custom USER EVENTS to programmatically generate events ie. you can trigger the start of your "automated handling" form anywhere in your code at virtually any time.
I think this would allow you to take advantage of the producer consumer architecture in its intended spirit, while integrating an automated routine.
I hope this helps!

Sound Input and Output Disappeared

I am considering a purchase of a used Macbook Pro (4,1) from early 2008 with Snow Leopard 10.6.8 installed. When I first tried the machine, the sound input and output were absent. After removing preference files, resetting NVRAM, etc., I finally got them to work. They worked for a few weeks, but recently they disappeared again. This time, my efforts to ressurrect them have been fruitless.
Here is what I have done in an attempt to remedy the situation:
•Delete com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist
•Jiggle a digital headphone jack in the headphone port
•Verifiy Disk and Repair Permissions
•Reset NVRAM
•Reset SMC
I have read online that some people have replaced the AppleHDA.kext file with the one from 10.6.7 - however, every effort I have made to find this file has resulted in failure. I am not able to locate MacOSXupdCombo 10.6.7.pkg anywhere on the web
Any recommendations? I was able to fix this once before - why not now? Thanks for any and all constructive input...

Did you recieve the install disk(s) when you purchase the machine? I would try doing a back up of your data then a fresh install of the OS. Insert the disk into the mac then click restart and hold the c key, ten follow the prompts.
If you wish to take this route, I would try the 10.6.8 combo update first (it should be fine to run it again), then if you wish you may try the 10.6.7 update. Altough I would just do a OS X reinstall and then run software update till you bring it up to date. On disk 2 there should be the AHT (Apple Hardware Test) that you can run by booting the disk holding the D key to check for a hardware fault.
You may also make a Genius bar appointment for a free evaluation, they have more extensive diagnosis tools and would then tell you what your otions would be. (hey it's free)
