Multi spread sheet files, continuously.

I am figuring out how to read the multi spreadsheet files continuously,
i tried bundled them and add them together but it dint came out as i expected.
the progrram i attched is fully working but only for 1 file.
anyidea how to make it to read many spreadsheet files and show as weekly, or monthly data analysis

Error 7 produced when saving to a spread sheet file using a compact rio

Hi
Im having a little difficultly saving to a spread sheet file using a compact rio. I bundled the data from a NI 9215 with a timer and stuck it into an x-y graph and that works fine as it goes round in shift registers. But then I passed the data out of my while loop unbundled it, turned it into a 2d array and tried to write it into a spread sheet file using the appropriate i/o vi provided by labview 8.2. I have hooked up all the requirements like format, and file path. But it keeps returning error 7 and says that my file path is incorrect. I’ve tried using a constant file path, ive tried creating the file before running the program, ive tried just writing the file straight to a disk in this case h:\test.asc but every time it comes back with error 7. I then went to a lab downstairs to see how they did it and the method I’m using it works down there but is exactly the same as mine upstairs. I’m a little confused by this one.
Any pointers would be much appreciated.

Hi
I apologise I didn’t specify I was only using a NI cRIO-9004 not realising you could get ones that had a USB port. I thought mine would behave in the same way as a DAQ device and write the file back onto the main computer hard drive. Is this not what happens if not how do you make it do that. The computer is a networked system with its own C:\ harddrive, but my personal space is on H:\ which must be like a pretend hard drive, or alternatively can you make the cRIO write it to a memory stick within a USB port of the programming PC itself. Or can you write onto memory of cRIO but then how do you download the data?
Also I apologise that I posted the message twice only did cos I thought it might be in the wrong forum.
Thanks

Auto Save to Spread Sheet file every N samples

I am in the need for a way to automatically save data to a file for every N-samples that are acquired. I've written the attatched reentrant subVI, but there are some problems. Whenever I have it in my program loop it hogs the process (stalling data acquisition) and just writes the initial values a bunch of times (the file quickly goes into the 10's of megs). I don't know where I'm going wrong in my algorithm.
Here is the algorithm I'm trying to realize with this subvi.
Inputs:
1. 1 x M array
2. number of samples to record at a time (N)
3. path to folder to automatically save files
Algorithm:
Initial run:
1. Create file name based on current date/time and folder path input.
2. Initialize an array that is N x M (so the number of rows is the number of samples to record, by the number of columns coming from the input).
3. Place the first row of input data into the first column of the array.
Subsequent runs:
1. Place the input data into the next position of the N x M array
2. If and only if current_input_count % N == (N - 1) then save the data to the autosave file. (note: %=modulus operator)
My typical sample rate is around 2-5 samples per second. I need this because some of our tests are really long (like hours long), and if the DAQ computer fails to save the final data set then we pretty much lost the entire test.
Sorry my G code is so sloppy. Thank you for any input. I'm targetting LabVIEW 8.

Auto Save N Points.vi ‏22 KB

For "automatically saving the data to a file for every N-samples that are acquired", you might have to use LabVIEW measurement file for storing your samples. Also, I have slightly modified your code. Double click on the LabVIEW Measurement file and then check different options available to store your samples. Hope this helps.
PS: Assuming that this is the only probelm you have, I didn't go through your algorithm.

Creat file to write to spread sheet

Hi all,
I'm trying to save my voltage and time data after DAQ. The data went
out OK. They are built to be a 2D array and I transposed them. I
wish to write them in Excel and thus can process data in that.
I used "File Path Control", "Open/Creat/Replace File', and
connected the refnum to "Write to Spread Sheet File". Now I have two
questions about writing to spreadsheet file.
First, I'm using Labview 8.0, and there is no dialog pops out even if
the "File Path" is empty. If I enter file path firstly, I have to
specify .xls in order to create a Excel file. How to make the dialog
telling me I haven't select a file path pop up in case I forgot and all
the data would be lost?
Second, Is there a way to append string head to a spread sheet? For example, time (tab) voltage?
Thanks a lot!

hi learner2,
if you want to wrtie to an excel file directly, you can try to use a wrtie to spreadsheet vi on the functions palette in file I/O . you can connect your 2D array to the input, specify the format and it will automatically ask you the location where to save your spreadsheet. Try using find examples and type "excel" in the search field to find more examples regarding spreadsheet .

How to find zeros in a spred sheet file

I have a spread sheet file having 33 column I want to find is there any zero in any of the columns,how this can be done easily.searching one dimensional array is time consuming since file size is very large
thanks for your time

If the spreadsheet file is a text file, you could use the string functions to search for the presence of zeros. The details would depend heavily on the format in which the data is saved.
For working with numeric values another caution is in order. In this case it probably would work to use the Is Equal to Zero comparison primitive, but remember that in general equality comparisons on floating point numbers are not a good idea due to the finite representation in binary and roundoff errors after calculations. Adapting Matt Bradley's suggestion you might test whether the absolute value is less than some tolerance, such as 1e-6, rather than zero.

Lynn- good point! but use abs val and compare to the machine epsilon (that "little e" constant on the numeric>constants sub-palette is the smallest value that the computer can represent as a dbl)

Graph to spread sheet

how to save a front panel graph to a spread sheet file programatically?

Hey Muralidharan,
I would suggest that you use ActiveX to generate your graph in excel. But this is a two step process, first you will need to save the graph to file. This can be achieved using an invoke node of the graph and setting a file location. Once the file location has been stored you can use the activex functions to insert it into your excel document. I have sent a link that should help you to generate the activex function for your specific problem. If you get stuck at any point please feel free to ask and I will help as best I can.

Here are a few Links to a helpful Knowledge Base article and a White Paper that should help you out: http://digital.ni.com/public.nsf/allkb/BBCAD1AB08F1B6BB8625741F0082C2AF and http://www.ni.com/white-paper/10435/en/ . The methods for File IO in Real Time are the same for all of the Real Time Targets. The White Paper has best practices for the File IO and goes over how to do it.

ALV truncation while download using List--Save/send--File--Spread sheet

Experts,
In ALV output, I am trying to download using menu item
"List --> Save/send --> File --> Spread sheet" then in the popup appears
here if i GIVE the FILE NAME THEN,material number is getting truncated.
If I don't give any file name it is storing as ".xls" and not getting truncated.
How to correct this or avoid this truncation.
OR
If we can't do correction about truncation ...my function consultant is asking to
to disable "List --> Save/send --> File".
Thanks in advance.
Sam

Solved by my own....
We need to pass
i_fieldcat-no_zero = 'X'.
so that the zeros at the end won't get truncated.

I want to open excel spread sheets make additions and export back to pc users. Is numbers suitable for this activity? I am using a MACBook Air

just read this in an other answer:
Pages can open docx files, Numbers can open xlsx files. Each can export to can export .doc or .xls to the newest Word or Excel format.respectvely, but not to the more recent .docx or .xlsx.
Translation is not perfect in either direction. Numbers and Excel handle some similar features (eg. pop-up menus vs data validation) differently, and the translator cannot translate from one implementation to the other.
If much of your work is going to be transferred between your machine and Windows machines running either MS Excel or MS Word, with editing taking place at both ends of the tunnel, then you'll probably be better off with Office, or one of the Office clones on the Mac end.

Short dump when exporting the ALV grid report in to spread sheet

HI,
I am facing a problem when downloading ALV grid report in to spread sheet LIST>EXPORT>LOCAL FILE -->SPREADSHEET.
in shotdump the cursor shows : "assign cline+cbegin(clength) to <field_cont>."
In SAP internal table LIST,in the first record the value of the filed LENG is 0. when i have changed this value ex:10 etc it is coming properly.
Kindly help me
Nagendra

Is this a standard SAP report, or your own? Can you tell what your report does, if it is a custom ALV report?

Is there a way to export and print the browser data as a spread sheet?

I'm in the process of logging approximately 1,500 shots for a documentary (the old fashioned way - long hand: shot #, TC in, descriptions... ) and I'm wondering if there's a way to export and print the data in the browser as a spread sheet. It seems like a pretty simple thing, but I don't see it any where. Am I missing something?

Yes, people I work with use it, assistants fill the fields out for me. As far as I know there is no "Print Browser" option. Some folks have assistants copy and paste the info into text, csv or xml files. Since everthing has gone to meta tags, this approach is going the way of the electric spoon or feeding mayonnaise to Tuna.
Peace & Covering Fire,

Can I use AW6 to open up a spread sheet, labled .txt ??

I received an important document from the county elections office today. I need to access the data for my campaign (local city elections).
It came with this note:
***Attached is the xxxxxx City voter file with voter history. It is a .txt format which can be opened with Access or Excel. There are 5,744 records.****
When I open, it opens by default with TEXT EDIT and I can see all the data (addresses, voting records, etc.). But not very useful format to me.
I am mostly an APPLE WORKS person...I like and am use to u sing AW. Is there a way I can put this into a an AW DB (prefer) or Spread Sheet so I can sort, and use the data? (Make address lists, labels, etc.)
This is new to me..
JON
PS: When I do the GET INFO on this doc, it says it is a Plain TEx Doc. Wish to make it a AW DB if I can.

By default, a new AppleWorks spreadsheet only has 500 rows. You can increase this to as much as 256 Columns by 16,384 Rows in Format > Document. Rather than pasting into an AppleWorks spreadsheet, use the Open dialog which will automatically create the correct number of rows. The same with a database. If you create the database this way, you will have to go back & use define fields to rename them.

How to export data from a spread sheet which has multiple work sheets?

How to export data from a spread sheet which has multiple work sheets to a single text file with fixed length fields?

Hello s1,
saving them as CSV will not give a fixed legth output but, as the naming says, a Character Separated Value file.

I am starting a new spread sheet in numbers to log my photos. I want to set up a sort button on each column but do not know how to accomplish this. Any ideas?

I have a Macbook Pro with the latest Yosemite operating system on it. I am using Numbers 3.5.2 and I am making a spread sheet for my photos. I am having columns with different information in them and I want the ability to sort them using buttons. Can anyone help me with this?

Bunnie,
The only way to prevent such loss is with a robust backup system. Apple provide TimeMachine as part of OS X. Connect an external hard drive to your computer and off you go. hourly, daily backups. I have recovered more than one computer this way,
As far as photos goes I use this approach:
1) Time Machine
2) a offsite copy of the picture folder from my user (I literally copy the picture folder to a separate, non-Time machine drive and relocate that drive in my desk drawer at work). I bring the offsite drive home every coupe months it refresh.
Numbers will not do a good job for this task (in my opinion) and will not facilitate metadata stored in the pictures. On bad thing happens in the number file and all your pictures are gone. In addition if you were to select the menu item "File > Advanced > Reduce File Size..." and, "BAM!!" all your pictures would be compressed and not their original size.
iPhoto keeps every change you make to a picture so you can get the original back. What ever happened with iPhoto will be much worse with Numbers (again, in my opinion).
Really set up a Time Machine backup. the drive should cost about $100, use it.

Multi spread sheet files, continuously.
