Program modification in 200249.vi

[venu]

Hey Beautiful People,

I need help in modifying the program and following is my problem: 

  I used to have LabView 6.1 on our old computer connected to DAQ card PCI-6023 E. I used to have lot of VI's on that computer for our needs. Among them one of the VI used to collect the data from multiple channels of DAQ and store it into excel file. Recently, this computer crashed and we have been forced to use another computer with Labview 7.1. The problem is that this multiple channel program is not working in Labview 7.1. 

I found out a program in NI developer zone which is similar to our previous program and works in 7.1. But, this program can only read the data but not store it. So can you please let me know how can I modify this program, so that I can save the data in the excel file.

I am providing the link of the program that I am using: http://www.mediafire.com/download.php?2ljwzwywzyy

thanks in advance,

sincerely

Venu

Do NOT provide your program via some offbeat hosting service! Use the attachment option below.

Also, if you mention a developer zone article, it only makes sense to provide the link to it. Do you expect some to repeat your search? Not sure why you don't just use the built in file I/O functions, though.

And lastly, 'not working' is a pretty poor description. If you can't clearly explain what exactly is the problem, then how can you expect to fix it.

This is a quick modification to show you the idea of how to save to a tab delimited spreadsheet type file, creating the file the first time through the loop, then appending to it on subsequent loops. Understand that depending on the sample rate, loop rate, etc., the file will grow in size rapidly, quickly becoming ridiculously large. Rarely do you need to sample thermocouples at a high rate. I did not test this, don't have the hardware in the demo.

Thank You very much LV_Pro for taking out some of your valuable time and modifying the program.

I have tried the new modified program and I now have a new problem.

My get this error when I double click the program:

An error loading '200249 new.vi'.

LabVIEW load error code9:VI version (9.0) is newer than LabVIEW version (7.1). 

Can you please help with this Problem.

Thanks in advance

Well you should have said you were using LabVIEW 7.1.

However, are you? Where did you get your copy of LabVIEW? Looking at the file you posted, it says it is LabVIEW version 7.0b61. That is an illegal, bootleg copy of LabVIEW.

You have some explaining to do!

Hadn't noticed that, was that a "beta" or possibly one of the "handout" cd's at the NI dog and pony, sorry, sales demos?

I donot know much technical details you guys are talking about. But I know that the Labview 7.1 I am using is totally legal under university of utah.

When your VI is opened and then closed with a newer, we get a prompt to save changes. Clicking on 'List unsaved changes' says 'The VI, last saved with LabVIEW 7.0b61...". When you go to Help>About LabVIEW, what does it say about the version?

Now I get it.

The 200249.vi file is given by one of the person with my program requirement. I have been using it. I donot know wether the person is using legal or ilegal version.I donot know what to tell more about it.Do you need more information regarding it?
