How can I read fast 50 MB Excel file in LabVIEW

Hi,
I have created a datalog file containing string i/p and having extension ".exl". File size is around 50 MB. When I read this file using LabVIEW, it takes 1/2 hour to display data in Array. How can I minimize this read time in LabVIEW. Or is there any options available to create large datalog files with string i/p and read it fast?
Examples are well appriciated.
Thanks.

What kind of file is it? If you are writing datalog files, there is no reason for giving them excel (.xls) extensions. Excel cannot read datalog files. The other way around, native excel files cannot directly be read by Labview.
In general terms this is what you may look into:
-use a compact file format like (real)datalog, fully binary or at worst plain ascii text file.
-you do not have to read the whole file into memory at once, depending on your application.
-look at your (RAM) memory space: it sounds like you are running very low on memory and the OS needs to pagefile most of it. Try closing all unnecesary programs and/or buy more memory. Also look for memory hogging inside your code: releasing data that is no longer needed will free memory used by labview. "Uninitialized" arrays for example may seriously slow down a computer.
my two cents,

How can I read the printer snapshot file printers.xml

How can I read the printer snapshot file printers.xml

XML files are typically viewed using a web browser.
Open the XML file and the default program should open it automatically. If you are prompted to select a program, use the option that lets you choose a program and brows through the directories for your browser (for example, use Internet Explorer, Firefox, etc.).
If need be, you should be able to right-click the file and select open with to choose the program to open it with.
There are other XML viewers out ther, but web browsers are typically the default as XML is a web language.

Hello Sae,
Welcome to the Sony Community.
What is the model number of the Reader Digital Book?
The Reader supports the text file (.txt) formats as well as the following two formats:
- EPUB file (.epub) EPUB (OPS version 2.0) supported
- PDF file (.pdf) Support is based on the PDF 1.6 specification.
The default language setting on your Reader Digital Book does not affect the language the book is in. To read books in a foreign language, you will have to purchase them specifically in that language.
Thank you for your post.

How can i read data in pagemaker file (PMD) using Visual Studio C# NET ?

I have bunch of data in .PMD file (Page Maker Document). Which contains mathematical equations and chemistry formulas, I am a .NET developer, and I am writing code for one of the educational learning system. For that I need to read and store mathematical equations/ chemistry formulas from .PMD file into database then display on the browser page.
Is it possible to read data from .PMD file using C#.NET, do I need to use any external libraries. How can I import .PMD to MATHML (Mathematical Markup language)?
Any existing examples for C#.NET?
Please help me regarding this.

I can't claim to know much about visual C# Net, but I do know a bit about pagemaker. It really can't handle equations. there are a few work arounds involving things like baseline shifts and multiple text boxes, but generally equations were created in different programs and placed in pagemaker in picture or eps files. Either way the chances of extracting usable data out of pagemaker is very slim.

Can I read a general excel file from BADI!!!

Hi People,
The requirement goes like this.
The user enters values (say a, b, and some amount) in some excel sheet (not in the BPC-like format), now the requirement is to read this excel sheet in the BAdI and do what ever calculations and other member findings i.e. based on the values of a, b i should be able to find out other dimension values and calculate other amounts and bring it finally to and appropriate form that fits into the application and write it back to the application.
The primary question is whether i can read a general excel sheet which is not in the form of BPC-like from a BAdI? if its possible, how?
Hope you understand this poor explanation. any help is much appreciated..
Kind Regards,
Surya Tamada.
Edited by: surya.tamada on Mar 23, 2011 9:15 AM

Hi Surya,
Yes, you can do everything in BAdI, even read data from unrelated spreadsheet. Question is, why do you need BPC then?
You can verify those values you have in that spreadsheet against Dimensions or if you going to verify those in BAdI you'll duplicate BPC effort. I'd strongly recommend not to go that route.
In ancient times I used FM WS_DOWNLOAD, but now it says 'obsolete', so may be try FM SDOK_WS_DOWNLOAD.
Hope you don't have to use it in BPC,
Gersh

How can i read my 1080 50p files from my panasonic camera

Hi all newbie here can someone give me the name of software that can read my panosonic HDC-HS700 1080-50p files from my camera i can read the HA 1920 files okay but just cant read the 1080 file, people tell me that the imac doesnt support the 1080-50p files but surely there must be some software that can read from my camera.
Regards to all Pete.

Hi EZ Jim,
After reading and following the info you sent through, i realised that the question i asked was totally wrong.
my question is that my mac cant read or even see the 1080/50p on the hard drive of my cam, because apparently the Panasonic HDC-HS700 is not compatible with Apple can you beleive that, so now i have got to go out and by the software from Panasonic install on a crappy windows machine and then onto a portable hard drive and then back into my Mac.what a load of c--p.
So thanks EZ for your help it was in any event usefull info that you gave me,
My very Best regards Pete.

I would like to have a readable version of my text message backup files. I have found the file but I can't read it in its current database format. Please help!

Why not read them on your phone? Or if the screen's too small for that to be comfortable, email them to yourself and read them on the Mac.

How can I read two channels with fieldpoint and labview

I'm trying to read two or more channels with the TC 120, and I follow the examples of sopport page, but doesn't work.
What can I do?

For more information about reading or writing to or from multiple channels in Fieldpoint, please refer to:
How Do I Read or Write to Multiple Channels on a Fieldpoint Module in LabVIEW?
This should enable you to read multiple channels. The only other option available is to use one fp open.vi, multiple Create Tag.vi's and multiple FP Tag Read.vi's.

How can i read comments from properties file in the right order??

Hello
I want to build a console that read a properties file and print to the screen the property name, property value and property description and the developer can change the name or the value or the description of the property and update the property file.
But the problem in using the properties class that it doesn�t read the comment and not save the properties in their order so I can�t couple description and name of the property.
Does any one know any utility that do the job or know how to solve the reading the comments problem???
Thank you a lot?

sorry but i dont understand how the solution of using
a dot ( property_key.description ) helping me to

So i'm as developer imagine that somebody edit properties in GUI or console. So you have 3 text fields: property name, property value, and propety description. Then developer save edit changes, then text fields maped to properties file and:
text field "property name" and text field "property value" construct property:
name=valuetext field "property name" adding ".description" and text field "property description" construct property:
name.description=descriptionFor one described property, you will have put two properties.
Thanks!
