Data file into spectrum analyzer vi
Does anyone have sample LV code to read a spreadsheet (text) file and display a frequency spectrum using the spectrum analysis vi ?
Hi,
In the LabVIEW Example Finder there is a Read from Text File.vi. This can be used to read data from a text file and display it onto a graph. The Spectrum Analysis.vi can be placed before the data graph in order to perform your signal processing.

Unable to Upload data from text file into BEx Analyzer selection screen
Hi,
No response from BEx Analyzer when I am trying to upload around 40,000 material from text file into BEx Analyzer selection screen using "Upload selections" options. But I am able to upload only 10,000 material from text file. I never faced same kind of issue when I am using BEx Analyzer 3.x. Please let me know I have to change any settings related to BEx or any other.
Thanks
Sri Krishna Ponnada.Hello
It seems you are reaching the .NET memory limitation informed in note 1040454.
Because 3.5 does not use .NET it can work that.

[Multisim]How to import data files into Multisim?
Hi guys,
In Multisim, we can plot various kinds of graphs, which again can be export to data files like *.csv. I have a csv file, which contains data in X and Y axes. How can I import this data file into Multisim, and make it displayed in a graph?
Thanks in advance.Hi,
The Piecewise linear source (PWL) accepts data as voltage or current vs. time. You can find this part by selecting Place>>Component, go to the "Sources" group then select "Signal voltage sources". Place this part on the work area, double-click on it and there should be an option to open a .txt file.

Geting an error trying to import a data file into OWB repository
Hi,
We're using OWB 11.1.0.7.0
I'm trying to import a new data file and I'm getting an error.
When I go to The Project/Files/ I right click on the module I want to add the files to,
I get a 'Wizard' titled 'Welcome to the Import Metadata Wizard'.
I click next.
I get the 'Filter Information' screen that asks if I want to select 'All Data Files' or a specific file.
I pick 'All Data Files' and click 'next'.
I get the 'Object Selection' screen that has a left and right panel. The left side is titled 'Available' and the right side is titled Selected.
The 'Available' panel had the directory in Linux (/etl/datafeeds/dev) where our data files are stored with a plus sign next to it.
When I click the plus sign, I get an error message that says:
API2836: Directory
/etl/datafeeds/dev does not exist.Has anyone seen this? What is the work around? Is it a bug? How do I import a data file into OWB if this isn't the way to do it?
Thanks,Hi, is there any obligation to use import wizard?
can you use right click and import view/table?

Merge data files into spreadsheet exports 1 field
In acrobat 11.0.5 the 'merge data files into spreadsheet' tool only exports the filename and 1 field. The form was created in livecycle designer ES3 and previous versions created in livecycle 2 and 2.5, using previous versions of acrobat have exported all fields when using the 'merge data files into spreadsheet' tool. IU there a fix for this?
Hi Lori
Many thanks the binding was set to 'none'.

Merge Data Files into Spreadsheet not working
HELP! I created the form files in Adobe Acrobat Pro XI, saved as Reader Extended PDF, have a submit button that emails me, and I download them to a folder on my desktop. When I try to "Merge Data Files into Spreadsheet" all I get back is the file name. I've tried with 10 files and only one file and it STILL won't work so it is not that the fields don't line up.
What do I do now?It's hard to say without looking at one of the files. If you can't post one somewhere, I'd be happy to take a look if you're free to email me: acroscript at gmail dot com

Split TempDB Data file into multiple files
Hey ,
I have been seeing TempDB contention in memory on our SQL server 2012 Enterprise Edition with SP2 and I need to split TempDB Data file into multiple files .
Could someone please help me to verify the following information:
1]
We are on SQL server 2012 Enterprise Edition with service pack2 but as per SQL Server 2012 Enterprise Edition under CAL Licensing –We are limited to use 20 logical processors instead 40 logical processors. Our SQL is configured
on NUMA nodes and with the limitation SQL uses only 2 NUMA nodes on live .There are 10 logical CPUs are evenly assigned to each NUMA nodes. Microsoft recommends that if SQL server configured on NUMA node and we have 2 NUMA nodes, then we may add two data files
at a time. Please let me know should I add two TempDB data file at a time?
2] We have TempDB Data and log files both on the same Drive of SQL server .When I split TempDB into two Data files, I can get them on the same Drive .What your recommendation should I need to create TempDB Data files on the same drive or on separate
disks?
3] What would be the blackout plan for splitting the tempdb into multiple files? Please let me know if someone has a better back out plan ?
1] Run script that create tempdb Database with a single file
2] Reboot SQL service in order to apply change
Your help will be apprecited .
Thanks ,

I am trying to import data characters from a tab delimited file into a table in labview. After I import the strings, I want to be able to select individual strings from the table and put into another table. I want the item that I am selecting to appear in a text box labeled 'selected step'. After I put all of the selected data in the new table, I want to be able to save that table in another tab delimited file (spreadsheet). This is what I have so far. Any help given will be GREATLY appreciated.

Selector.zip 30 KBHi,
Here are modifications to your vi to do what you are describing. It helps, when trying to work through issues like these on this forum to not start a new thread with each iteration of your question. Those of us that are trying to help can follow it better if you just "Reply" to your previous thread with the new, related question. If the question is for a totally new issue then a new thread is best, but when you are working through the details of essentially the same problem it really helps us follow it if you stay in one thread, and that usually means faster answers.
We also like it if, when an answer helps, you give us a rating (the more stars the better) as it is about all we get out of it!

I have an XML data file that I want to use to populate a pdf fill-out form. There is enough data in the file to populate several forms. Is there a way of moving each set of data from this XML file into a seperate pdf fill-out form?
Hi,
There are many ways to convert XML files to PDFs through java.
One of the easiest way is by using iText.jar which have classes for conversion.
The following are the required steps
1. Create a document object for the XML file ( Using DOM or SAX parser).
2. Parse the xml document and extract the content to write in PDF.
3.Create a itext Document object.
4.Get a PdfWriter instance for the PDF file.
5.Write in the pdf the extracted text using the document object.
Refer <a href="http://itextdocs.lowagie.com/examples/com/lowagie/examples/general/HelloWorld.java">here</a> for a simple pdf writer example.
Refer <a href="http://java.sun.com/developer/codesamples/xml.html">here</a> for examples of XML Parsers.

Can I import .dat files into iMovie?
Hi..I received 2 .dat files which play in Quicktime. They are pieces of 2 movies which were converted from Video and given to me on a cd disc with a website.
I want to edit the movies and also lighten them up, because they is very dark.
I am wondering if I can import them into iMovie and be able to work on them? Or would it have to be Final Cut Pro? And how would I get them in there, make a duplicate (in order to save these originals) and then do editing and use them both for the website, as a mpeg4 or 3 and also as files for output to cd's? Can I get them out of the .dat file format?
Obviously, I know nothing about this. Thank you.Sue,

Hi,
I am facing a problem in XI. I have a file Adapter which fetches the data file from the appln server. For the testing purpose we kept the adapter disabled and placed th files in the directory. When activating the adapter, it fetches all files and brings to XI.
Now the adapter is enabled. If I am trying place the data file in the application server while the adapter is enabled, the file simply disappeared/archived as per the setting in adapter. But the data is not coming into XI.
This problem occurs only when the adapter is on and placing the files in the server.
Can any one help me on this?
Thanks.

How to import old Contacts Card Data files into 10.8.5 Contacts app
My old Snow Leopard Macbook died but its hard drive lived.
I was able to find the Address Book contacts but they are in a format that the new Contacts app doesn't recognize.
Its kind is "Contacts Card Data" and each file ends with ".abcdp".
How can I import these files into the new Contacts app? Contacts does not seem to want them. Do I need to convert them to v.card?
Thanks.I've had no exposure to 10.8 or even 10.7, but the following should work, with 'AddressBook' replaced by 'Contacts'. (It's copied from https://discussions.apple.com/thread/1436528. It worked for me in 10.6.8.)
Quit Address Book.
Make a copy of folder ~/Library/Application Support/AddressBook in case anything goes wrong.
Delete AddressBook-v22.abcddb from ~/Library/Application Support/.
Put your abcdp files in folder ~/Library/Application Support/MetaData.
Restart Address Book. -
Can I import .dat files into FInal Cut Pro?
Hi..I received 2 .dat files which play in Quicktime. They are pieces of 2 movies which were converted from Video and given to me on a cd disc with a wesite.
I want to edit the movies and also lighten them up, because they is very dark.
I am wondering if I can do it in FCP? And how would I get them in there, make a duplicate (in order to save these originals) and then do editing and use them both for the website, as a mpeg4 or 3 and also as files for output to cd's? Can I get them out of the .dat file format? I have FCP 4.5.
Obviously, I know nothing about this. And I have posted this also in QT and iMovie..to see what I can do. Thank you.Thank you.
I will try this.
I cut a cd on Toast 7 and it plays on my DVD player, but still in the DAT format.
I was also given this link
You may want to try this freeware and use it to convert the dat file to a DV Stream which you will be able to open in iMovie, do your editing, and then export or "Share" to a .mov file. Mpeg StreamClip < </div>
http://www.squared5.com/
I will try what u have written first, as it seems simplist.
I also found out that these clips are in PAL format. Will that matter?
Thanks for the info from Apple. I am in India and will see how I can do this. -
Import data from a spreadsheet (data file) into TestStand steps
Hi,
I have some 100+ customers with different configuration data. Whenever I need to run test for a different customer, I need to update the TestStand steps in each sequence file with new values.
I'm thinking if there's a better way to simplify this, perhaps by using a spreadsheet/data file to input the data? But I have no idea how to do this?
My steps are from two sources, one type is a dotNET DLL, another type is Active X/COM (calls TestComplete software).
Any suggestion would be appreciated!
Thanks!
ph2Yes there is, make use of the PropertyLoader. Checkout the examples found in the TestStand Examples folder.

The Step goes on till like 3000, I am creating an object for each step which inturn has nested object for each well and the well in turn for each layer. In the above case of step 3 the object would be
class Step 2{
inner class well
{ //for well 1
inner class layer { // for layer 1 }
inner class layer {/ for layer 2 }
inner class layer {/ for layer 3 }
inner class well
{ //for well 2
inner class layer { // for layer 1 }
inner class layer {/ for layer 2 }
inner class layer {/ for layer 3 }
This architecture of mine is proving to be heavy as I would end up with around 9000 Java objects in memory, though my classes only have have int, float, String data items. I am using this data to plot graphs, so I guess it wouldnt be optimal to read data from text file for each plot.
So in short the problem is can anyone tell a better way to read the data into memory ? given that there could be 3000 steps in the format given above.
Thanks
AMI have implemented and it takes around 30-45 sec to parse and also the GUI has become very slow. I query the objects for multiple combinations of graphs.
The data from the objects is being used to feed the graphs on my GUI. I have a number of options on my GUI for different kinds of graphs, for each combination chosen the Objects are queried for the data. The GUI is written using Swing.
So is there anyway I can fine tune the application, any tips about the object architecture or how to improve the speed. I am also explicitly running the garbage collector a few times in my program. Also how can I make JVM occupy lesser memory so that my program can have more memory.
Thanks
