Multiple Arrays to Spreadsheet

Hi,
I've a vi that process data files and saves the analysis on a new file (it's a 2D array). This being done in a for loop to allow multiple files to be processed with user intervention. Instead of saving a new analysis file every iteration, I would like to save all of the analyzed data in one file. For example:
Cable #11
x y z
1 2 3
4 5 6
Cable #12
4 5 4
3 2 2
The two problems I have:
I know how to insert headers but how do you insert a string after each array?
How do I save all the arrays to one array? I've tried taking the spreadsheet function out of the for loop, but it didn't work.
I'll appreciate any input,
Solved!

I've tried appending it in & out of the for loop and it doesn't make a difference; it just writes the last data file.
Thank you for taking a look at it. The data I want to save is the case structure outside of the for loop.

Writing multiple arrays to a single xml file at seperate times without overwriting the previous file?

Hi my name is Dustin,
I am new to labview and teststand... I am trying to right multiple arrays of data to a single xml file. I can do this with a cluster but I have to create a variable for each of those arrays (21 arrays) and I was hoping to use the same variable for each array. Meaning I obtain my array of data write it to an xml file then replace that array in that variable with a new array and then call up my VI that writes that array to an xml file and write it to the same xml file underneath the first array without overwriting it. Attached is my VI I created to write an array to an xml file. Again I am wondering if there is a way to write multiple arrays to a single xml file at different times without overwriting the previous xml file.
Thanks

Array to spreadsheet string - remove space after delimiter

Hi
I created a Labview program to acquire a electrical signal and send it using TCP/IP.
The image in attachment shows a piece of my code. The AQ subVI was created by me to accomplish the acquisition.
However, the string that the "array to spreadsheet string" VI returns is something like this:
-0.800781^ -1.030273^ -1.098633^ -0.942383^ -0.644531^ -0.209961^ 0.258789^ 0.712891^
The VI is using the ^ character as a delimiter and it is converting commas to points as decimal separators.
Now, what i would like to do is to remove the space character between the ^ character and the sample value, simply because that is what the receiver of the TCP/IP message wants.
Can anybody help me?
Thanks in advance

Obtain Array from an XML file with Multiple Arrays

Hi,
So I have been struggling with this program I am making for the last few months but I am almost there. I have a program that creates multiple arrays and place them one after another in an xml file and each array has its own unique name. Now I would like to create a VI that takes this XML file and when the user inputs the specific array name they are looking for it goes into the xml file finds the entire array under that name and displays it in an output indictor to be viewed on the VI. Attached is a sample of my xml file and the VI that creates this xml file.

Writing arrays to spreadsheet w/ timestamp

Hi. I'm trying to build an application which will write a set of thermocouple values to a spreadsheet with a timestamp at the beginning of each row. What I have so far is a countdown loop which gives me regular intervals of time. When the loop reaches zero, the set of values in a global array variable goes into an "Array to Spreadsheet String.vi" then I use the Concatenate string to put a timestamp string, a space and the spreasheet string. Since "Write to spreadsheet.vi" needs an array input, I have to use the "Spreasheet string to Array.vi" then to the "Write to Spreadsheet.vi" So what this does is writes the TC values, but the timestamp gets lost somewhere in there and it write a completely wrong value
which looks nothing like a timestamp.
I appreciate any comments on this.

In order to add a timestamp to each row, you will need to use the "write characters to file" VI. Since a spreadsheet is just a tab-delimited text file, you can use the "array to spreadsheet string" function to convert your array of data into a tab delimited string. Once you have this string, you can concatenate your time data to the start of it and write the resulting string to file.
I have created a simple example that writes randomly generated numbers to a spreadsheet every 0.5 seconds with a timestamp for each row. Hope this helps!

Deleting all elements from array and array to spreadsheet string

Hello,
I would like to write a new data file for each "recording" session without closing the VI. My problem is that the last "recording" session's data is at the top of every successive session's text file. I do not want this. I've tried to delete all rows from the array after my array to spreadsheet string function, but I think the problem is somewhere with the shift register and how the array is built. I'm not too familiar with LabView and this aspect of my interface is driving me crazy. Attached is my code and two successive data files. I have not been able to find a solution on these or the LAVA forums. Any help would be appreciated.
Also, I know there is an easier way to write this kind of streaming data, but I need to do it this way for other devices and synchronization purposes.

A few more comments to your code:
Your loop does not have a wait, meaning it spins the empty case millions if times per second, consuming all CPU while not doing anything. Add an indicator to [i] to see.
To clear a 2D array in one case frame, just don't wire the output tunnel and set it to "use default if unwired". You'll get an empty array. No fancy tools needed.
I probably would use an event structure and also protect the data if the save dialog is canceled.
Here's a simple draft that probably requires a bit more work but should show some of the ideas.
You should also
add some protection that the VI cannot consume all available memory if it runs forever.
Create a seperate case to save the data later if the file dialog is cancelled the first time.

Trouble with array to spreadsheet string

I am having trouble with the array to spreadsheet string.
I have a 1-d array of string, the output spreadsheet string never puts a space on the first row, but all others.
example:
05:59:29.170    00000101     8        00 00 07 00 0B 0E 0D 0C
05:59:29.198    00000100     8        00 00 3A 3A 39 39 39 39
05:59:29.220    00000101     8        00 00 07 00 0B 0E 0D 0C
05:59:29.248    00000100     8        00 00 39 39 39 39 39 39
format string is %s and default tab is delimiter.
this is screwing up my program because of the "scan for string" function can't be used correctly if the spreadsheet string isnt consistent.
Any suggestions?
Thanks

You don't need to use "array to spreadheet string": You could use plain formatting for full control over the output.
Still, your observation is a bit odd. Could you attach a simple VI that shows the behavior? (Put your input array into a diagram constant).

\0D and \0A after array to spreadsheet string conversion

Hi guys, i currently have a VI that manipulates a couple of arrays and writes them to a config file through the config VI.
Now, i notice 1 problem whereby after my array is comma delimited and converted into a spreadsheet string, a tab and carriage return automatically appears at the end of the string. This causes my resulting config file to have \0D and \0A to appear with my keys in the config file.
I know it's got to be the array to spreadsheet string conversion that's causing the problem because i don't have such \0D and \0A problem with keys without the conversion.
How do i solve this?

The OD and OA are the carriage return and line feed and yes the functona always appends these characters at the end of each line. Probably because this function is normally used to create files that a spreadsheet can read. There are several ways to remove the extra characters. Shown below is the string reversed and the String Subset function uses an offset of two. The output of that is reversed to get a string without the CR and LF. Also shown is getting the string length, subtracting 2 and wiring that to the length input of the String Subset function.

Array To Spreadsheet String and DDE

I have an array (one dimensional) that I want publish as a dde topic.
So far I've been able to write all my dde components appear to be working,
with the exception of the dde set value function in conjunction with Array
To Spreadsheet String function.
Array to spread appears to parse the the array the way I want it (that is,
to create one
big string with newline chars seperating tokens) but it's output does not
seem to set correctly. If I look at the value right after I convert it to
a spreadsheet
string its good, but if I check it (once it's been loaded) using
DDE Srv Check Item it comes up blank.
Does anyone know what I'm doing wrong? I'm feeding the output of array
to spread driectly into DDE Srv Set Item, shou
ld it be going through another
function first? Or am I using the wrong function to parse my array? My
DDE
server seems to work ok if I just use single string values, is there something
about using arrays that I should be aware of? Any feedback is appreciated.

Hi aschipfl,
some thoughts about your suggestion:
- When you want to suggest improvements to LabVIEW you should post in the Idea Exchange.
- NI will not change the behaviour of functions existing for a long time…
- NI will probably update the LabVIEW help for that function…
- a spreadsheet string needs some kind of delimiter, what's the purpose of creating a spreadsheet string without them?
When you really need a "Array to Spreadsheet String" without delimiters you could take this approach:

Array To Spreadsheet String, Empty Delimiter

The Array To Spreadsheet String function does not accept an empty Delimiter, it uses the Tab character in such case.
The same is true for the Spreadsheet String To Array function (but of course this function cannot work without a Delimiter).
I would appreciate one of the following options:
to allow an empty separator for both functions (for Array To Spreadsheet String this can easily work obviously; for Spreadsheet String To Array you might see an empty string delimiter between each two adjacent characters similar to the Search and Replace String function with an empty search string);
to document that behaviour properly;
I would prefer the first option espacially for the Array To Spreadsheet String function. What do you think?

Multiple Arrays for limiting Record Pulling in Main Report

I have created an array in a subreport that pulls all applicable order #'s for a specific period. The subreport has been placed in the report header of the main report. In the main report, I have a formula that looks at the order # in the database. If that order # exists in the array, then I want the main report to pull that order # and the related invoices. One order # can have more than one invoice.
I've used the above method many times to limit records pulled when I had less than 1000 applicable records. Now, out of necessity, I'm trying to do this with more than 1000 records, so I have created multiple array strings within the "array" formula. The "array" formula is working correctly - the data that I see is correct. The problem is with the formula in the main report. This formula is not returning any data - so, basically, the main report formula is saying that no order #'s exist in the array.
Here's my coding for the array (appears to be working fine since the data looks correct):
whileprintingrecords;
shared stringvar array Groups1;
shared stringvar array Groups2;
shared stringvar array Groups3;
numbervar rtc1;
//if pymt receipt date is in the report period, add that order# to the array.
if {BI50_BankTransactions_AR_InvcDt_H.ValueDate} = {?Cash Receipt Period}
then
(redim Groups1[1];
redim Groups2[1];
redim Groups3[1];
rtc1 := 0);
// the code below checks to see if the order ID field is in any of the above-declared arrays...
//if it is it is not added again and rtc1 is not incremented
if not({oehdrhst_sql.ord_no} in Groups1 or {oehdrhst_sql.ord_no} in Groups2 or {oehdrhst_sql.ord_no} in Groups3) then
rtc1 := rtc1 + 1;
if rtc1 <= 1000 then (Redim Preserve Groups1[rtc1]; Groups1[rtc1] := {oehdrhst_sql.ord_no});
if rtc1 in 1001 to 2000 then (Redim Preserve Groups2[rtc1-1000]; Groups2[rtc1-1000] := {oehdrhst_sql.ord_no});
if rtc1 in 2001 to 3000 then (Redim Preserve Groups3[rtc1-2000]; Groups3[rtc1-2000] := {oehdrhst_sql.ord_no});
if rtc1 <= 1000 then Groups1[rtc1]
else if rtc1 in 1001 to 2000 then Groups2[rtc1-1000]
else if rtc1 in 2001 to 3000 then Groups3[rtc1-2000]
Now, here's the code for the formula in the Main Report (please note, for now I'm just trying to generate a "true" or "false" result - so my current results are all "false" which isn't correct)
whileprintingrecords;
shared stringvar array Groups1;
shared stringvar array Groups2;
shared stringvar array Groups3;
({oehdrhst_sql.ord_no} in shared stringvar array Groups1) or
({oehdrhst_sql.ord_no} in shared stringvar array Groups2) or
({oehdrhst_sql.ord_no} in shared stringvar array Groups3);
If I only use one "shared stringvar array", everything works like a charm, but when I add another "shared stringvar array", the formula in my main report stops working. I've tried changing this code but nothing has worked. I'm at a loss as to what the problem is. Any suggestions would be very much appreciated.
Edited by: Linda Offenbacker on Sep 21, 2010 9:41 PM
I have resolved this issue. I guess seeing my coding in a different perspective helped me identify the issue. The problem was in this section of the code where my redim criteria was incorrect:
"if {BI50_BankTransactions_AR_InvcDt_H.ValueDate} = {?Cash Receipt Period}"
It should be:
"if {BI50_BankTransactions_AR_InvcDt_H.ValueDate} <> {?Cash Receipt Period}"

Also, keep in mind that you only need a sub-report if your table joins are one to many records. If they are = joins then you don't need a sub-report if the tables are linked in Crystal correctly.

Write array to spreadsheet string

Hi,
I have 3 numeric arrays and 1 string array. I am try to use the function write array to spreadsheet string. What is the easy way to do this, since I have both numeric and string, I can't create a 2d array directly?

It depends how you want the file to store the data.
Attached is an example of two methods mentionned above. You can change the formatting so that you have the data on the same line or different lines.
There are many solutions depending on exactly what you want to accomplish.
--- didn't expect to see so many replies so quickly ---
Most people recommend converting the numeric array to string array first. I offer an alternative or a choice of both..

Array to Spreadsheet suppress errors

Is there a way i can supress errors from an Array to Spreadsheet node.
If the file is open and it cant write to it then it creates an error box and the VI stops running until you click continue. I simply want it to ignore the error and keep running without writing to the spreadsheet.

Since this is not a low level File I/O VI, it does not have error terminals in/out. I would suggest you to use a low level VI set, like the "Open/Create/Replace File", Write to Text File", and the "Close File" VIs. In this way you have more options to catch and handle the error.
Or you can modify the high level "Write to Spreadsheet File" VI to have error terminals in and out (and deleting the pop-up terminal from inside)... But NEVER ever modify&save an original LabVIEW system VI, first save it under a different name and location!

Sorting between multiple arrays.

I thought that I had posted this yesterday; however as I can not find my post...
I need assistance with part of a project where I need to sort between multiple arrays; using one of the columns as the sort criteria. The arrays contain integers, strings, and doubles; however I would like to sort and display the arrays alphabetically using the string column. I was told that a bubble array may work, however as I can not find specific information on the use of a bubble array, I really don't know where to start. The arrays look like the following:
productArray[0] = new Product(1, "binder ", 15, 1.5, 0, 0);
productArray[1] = new Product(2, "marker ", 13, .5, 0, 0);
productArray[2] = new Product(3, "paper ", 24, .95, 0, 0);
productArray[3] = new Product(4, "pen ", 5, .25, 0, 0); \
Any assistance that anyone could provide would be greatly appreciated. I am a newbie when it comes to Java and the course materials are extremely vague.

Multiple waveforms to spreadsheet

I am aquiring episodic data, say 2seconds at 20kHz then a 30 second interval and more data. I am saving this in a tdms file and all is fine.
I would now like to export these waveforms to a tab delimited spreadsheet, and I like the header etc that the cannede vi's offer. However when I set the append option to false, there is a new file for each waveform. When I set it to true, the next waveform gets appended at the bottom (same columns, new rows) instead of as new columns same rows. With the write array to spreadsheet, there is a transpose option. Is there something analogous for waveforms, or will I just have to use the write to spreadsheet and make my own headers etc?
thanks a ton!
