Write spreadsheet help

Being very new to this I am finding many of the examples to complicated to follow. Can someone give me a very simple example of the write to spreadsheet function
Just show me how to write three pieces of data to a row I would like to see a number, string, then number. Once I understand the basics I have pretty much been able to figure things out the rest of the way on my own.
thanks in advance

Mike my application is very similar to what you posted can you look at my vi I have attached it it was done in labview 8.2. I cant figure out why my data is not a row when i open the csv file it looks like my carriage return happens after each item rather than after the entire string.
Change the format input to %s (currently %s\r).

Error 5 occurred at Open/Create/Replace File in Write spreadsheet String.vi

Hi everyone,
can anyone help me with this problem?
"error 5 occurred at Open/Create/Replace File in Write spreadsheet String.vi "
I've been using this part of the program for over a year an suddenly this error occures. But not always, mainly at the very beginning of my tests when the file should not be open.
Info: I'm using a realtime PXI-System. Maybe the amount of data can cause the problem? (about 2MB)

Hi Meike,
is the file opened by a different program? Do you try to access it by FTP in parallel to your VI?
You could use basic file functions instead of WriteSpreadsheetFile. That way you could open the file before starting the loop, keep it open all the time and close it once you're finished - with the added benefit of easier error handling…

Write spreadsheet column limitation

Hello, I'm trying to use write spreadsheet to save my structure of arrays.
I use an insert into array to join some arrays (10). I've got 450 variables (%.3f).
But when I read the saved file, it's showed me 30 Columns*15 lines columns instead of 450 columns *1 line.
In those arrays I've got SGL, INT and UINT variables.
My questions: 1) Is there any software limitation for that? Or I have made some mistake.
2)When I look at my saved file, the SGL variables should bring me, for instance, 3.145 or 127.236, but it brings me 3.000 or 127.000.
Please, is there anybody that can help me on that?
Regards
Felipe

Hi Kitofelipe,
the difference is easily to spot:
the build array results in a 2D array (it's not in "concat" mode), the insert array will give a 1D array. Just create indicators to see this (or move the wiring tool over the output connectors of both functions).
In your other eample you work with a 2D array in the shift register, so you will (nearly) always get a 2D spreadsheet file...

Write Spreadsheet To File even if path doesn't exist (yet)

I am interested in using Write Spreadsheet To File to log some data to my disk. What is the easiest way to include this VI and tell it to create the folders if they don't already exist.
For example:
Using that example, if no "Data" folder can be found on my Desktop, how can I have LabVIEW create the "Data" and "Test1" folders necessary to create Test1.csv in the specified location?

Bug in writing Integer Data in Hex in Write Spreadsheet File

It appears that Write to Spreadsheet File forces all data to I64. Try writing an I16 or I32 array with a negative number. Format specification to 4x, 8x or whatever is ignored and you get a full completent of 16 bytes with a lot of FF's at the beginning making it I64

Hi;
it's not a bug it's a feature :-)
Whenever you want to format numbers the formatting routine will try to leave as much digits as needed/possible. When you format I8 then 2 digits are ok, I16 needs 4 digits and so on.
You can easily test this behaviour when using the 'Array to spreadsheet string' function (it's also used inside 'Write spreadsheet file'). When saving negative integers as Hex formatted ALL digits are needed to describe the number and so you get all of them in your text file!
The only problem is: 'Write to spreadsheet file' only knows about I64. Whenever you want to save negative numbers you get 16 digits regardless of format string.
Solution:
Change the 'write to spreadsheet file' as described before or do the formatting on your own by using 'array to spreadsheet string'!

Sorry,
i guess i attached the wrong picture.
i currently have this.
I read from a spreadsheet.
and analysis certain row and column, then do calculation and write the results to a new spreadsheet.
it is working fine.
but as an option. i wanted to "read all the data from the spreadsheet as the previous image" and then write those data to the same new spreadsheet file but in a different worksheet.

Donde coloco un WRITE SPREADSHEET?

Hola , ya he creado un programa para obtener un graph XY a partir de datos leidos de una tarjeta de adquisicion de datos ( 1 dato de X y otro de Y), ahora m falta guardar los resultados de la curva obtenida en una hoja EXCEL, así que he intentado usar un write spreadsheet dentro del while de mi programa pero solo me guarda los dos primeros datos, donde lo tengo q poner para q m los guarde todos?tengo q crear algun array? muchas gracias

Intente poner el exterior de la función de la hoja de balance del escribir el lazo del rato. Usted necesitará separar los datos de X de los datos de Y. Sea seguro que la indexación de direcciones automática está permitida en los datos de Y combinar los datos en un 2D arsenal y que inhabilitada en los datos de X. Combine los órdenes (1D + 2D) para escribir al archivo.

Error 6 occurred at Open/Create/Replace File in Write Spreadsheet String.vi- Write To Spreadsheet File (string).vi- Untitled 1

Hi I'm getting the above error when attempting to get a file path control to write to a spreadsheet vi?
The spreadsheet is opened in open office but saved as a .xls in the documents folder.
The spreadsheet only contains one row and three columns each with text contained but when I run the VI and then open and view the actual speadsheet all three headers appear together in the A1 cell before the title error message appears.
Is Labview not compatible with open office? Perhaps someone can confirm if this is indeed the case?
Thanks in advance...

Solved. One just needs to click seperate by tab in the import dialog than opens in OO calc.

Cfscript I'm trying to write Please help :)

I wonder if some one could help with a cfscript I'm trying to write.
A have a number eg
135
4245
1
I want to turn these into a string with length 6 with zeros at the start like so:
000135
004245
000001
thx 4 any ideas

Here's a cfscript along the lines of what you asked for. There's other ways to do it, of course, but I thought this approach would be helpful to you.
<cfscript>
/* takes a string as an argument and adds as many zeroes as it takes to make the string be exactly 6 characters. */
function PadWithZeroes()
var VarToTest = "";
var ValToReturn = "";
var VarLen = 0;
var DesiredVarLen = 6;
if (StructCount(Arguments) EQ 1)
 /* Use Trim(Arguments[1]) only if you do NOT want to add zeroes to one or more empty spaces */
 VarToTest = Trim(Arguments[1]);
 VarLen = Len(VarToTest);
 TimesToLoop = DesiredVarLen - VarLen;
if (TimesToLoop GT 0)
 for (q = 1; q LTE TimesToLoop; q = q + 1)
 VarToTest = "0" & VarToTest;
 ValToReturn = VarToTest;
 return ValToReturn;
else
 return false;
// the rest is for testing/viewing the function etc.
NumberToUse = 4;
if (IsDefined("URL.NumberToUse") AND Len(Trim(URL.NumberToUse)) LTE 6)
 NumberToUse = Trim(URL.NumberToUse);
</cfscript>
<cfoutput>
 
NumberToUse=#NumberToUse#
 
 
PadWithZeroes(NumberToUse) = #PadWithZeroes(NumberToUse)#
 
 
</cfoutput>

File is locked, on a locked disk or you do not have write permission. help!

When I click on iTunes, I get the message "The iTunes Library.itl file is locked, on a locked disk, or you do not have write permission for this file." It started happening yesterday. What should i do?

Perhaps this Apple Knowledgebase article will help:

Good luck.

Every time I download a large file in safari (mavericks version) at the end i get the error cannot write file. help

evrytime i dowload a file on my macbook pro it tells me at the end that it cannot write the File. Small files download Ok but Large files do not.
Help Please.
mackbook pro 13 late 2012 upgraded to Mavericks restored backup from M lion with time Machine.
Thx

I am experiencing this as well. I've found a workaround. Once you know the file has stopped (the Safari download menu says it cannot write the file) then do the following:
1. Open the Downloads folder.
2. Open Terminal.
3. In Terminal type "cd " and then drag the "incomplete" .download file to terminal (this just copies the path), then hit "Return" and you will change into the directory.
4. Type "ls -l" and you should see within the .download bundle, the complete file is actually there and complete.
5. Now, let's say the file name is "file.mp4" type "mv file.mp4 ../" and it will be moved out of the bundle one level up into the Downloads folder. You may need to enclose the file name in quotes if it has any special characters.
6. You can now drag the .download container to the trash, and the file should be fine.

Write bmp help inconsistent

In labview 2011, the help reference on the "write bmp" vi is different than what is shown in the block diagram context help dialogue for the necessary data types. The help reference has the first (2) elements in the cluster as U16 and U8, image type and image depth, respectively. However, the context help shows these both as I32 (i just connected a broken wire to the "image" input on the write bmp icon in the bd, and turned on the context help, which displays the expected data for that input).
Which is correct?
Solved!
Go to Solution.

The function is correct, the detailed help file associated with that function is wrong.
Interestingly, the Read BMP help file shows the correct datatypes.
Good catch! Someone from NI will probably issue a CAR# to have the documentation corrected.
