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 .

Create new users from an excel spread sheet

Hi Everyone.
I am very new to SAP and I have only done the ABAP programming course last month.
To make mme become familiar with ABAP - I was given a task of creating users from an Excel spread sheet - This will be used later on when we implement the new SAP system and decommision the legacy system.
I am just wondering If anyone has created such program - I would appreciated If I can have a copy So I can learn how it is done -
At the moment, I was thinking of using BAPI_USER_CREATE1 and BAPI_TRANSACTION_COMIT to create users and optimise the creation call. Is there any thing else that I should be aware of ? I'd be appreciated if someone drop me some ideas - Thanks in Advance

Hi Samantak.
Thanks for your quick response.
Since posting the question, I discovered that within 'BAPI_USER_CREATE1' sub-call statements - comit is already done. Now my questions are:
1) Do I still need 'BAPI_TRANSACTION_COMIT' to optimise the CREATE new newusers call ? Apparently, yes.......I am curious for the reason 'why' since comitting is already done.
2) I did an interactive call of the 'BAPI_USER_CREATE1' - a user id was actually created in the system. Now, my second question is.. Is there a way of calling 'BAPI_USER_CREATE1' without comitting the data (i.e. create user record on file)..
I want to call this whout comitting because I want to sort out the number of 'good' records from the supplied data list - and presenting the success percentage to the users before comitting the data.
Thanks

Writing to spread sheets with more than single precision

Hi everyone,
Im recording data by using the write to spread sheet VI in Labview 8,
it records single precision which is a problem for me as I require greater
precision.
Are there ways around this issue?
Thanks
Solved!
Go to Solution.

What do you mean by this? Is it possible for you to post code which only shows what you are trying to explain?

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.
Dan

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

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…

How to create files with read/write privileges for everyone?

I have two iMacs 7,1 (one with Snow Leopard and the other with Mountain Lion) in a local area wireless network.
I have shared the "documents" folder in the Snow Leopard iMac in order to have files available to the other iMac. The folder has read/write privileges for everyone.
When I create a new file in the shared "Documents" folder (for example a new Open office document, or a Keynote presentation) this file is by default "read/write" for the Administrator but only "read" for all the other users, so when I try to open it from the other iMac, I am informed that the file is "read only".
I can obviously change the privileges of the file in the information window, but I have to do on a file per file basis and this takes too long.
Is it possible to change settings in order to create files which are always "read/write" for everyone?
And, secondly, since I have several existing files whose privileges I should manually change one by one, is it possible to make global changes of their privileges?
Thanks in advance
Best regards

couple of different changes - 1st, if you want to share folders, doing your whole documents folder is not the best way. Since both your computers can handle AidDrop, that's what I would recommend - http://osxdaily.com/2011/11/14/how-to-use-airdrop-in-mac-os-x/ - as it create an instant Ad-Hoc network between the two computers and then let's it done.
A second possibility that may not be what you're looking for, is to use google drive or some similay cloud sharing app to sync the documents back and forth. both of these solutions will transfer the files well, but the airdrop may be simplest

Create xml file and write data in to it:

Hi All,
I have a small requirement here.....
I have a java program which reads a xml file.
Now i have stored the contents of that file in to a java object.
I want a sample code now which would take theabove mentioned java object as an input ,create a xml file and write these entries in to the file.
Can anyone help me in this?
Your help would be appreciated.
Thanks in advance.
vrkr

Hmmm. There is nothing special about an XML file to any other file. The data is simply formatted in a certain way. So to write an XML file, it is no different to writing any other form of file in Java (assuming you know the structure of the xml format to write - which you should)
If you don't know how to write files using Java I would suggest using the Java Tutorial found on java.sun.com and do some reading up about I/O since this is fairly fundamental.

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.

Wait Events "log file parallel write" / "log file sync" during CREATE INDEX

Hello guys,
at my current project i am performing some performance tests for oracle data guard. The question is "How does a LGWR SYNC transfer influences the system performance?"
To get some performance values, that i can compare i just built up a normal oracle database in the first step.
Now i am performing different tests like creating "large" indexes, massive parallel inserts/commits, etc. to get the bench mark.
My database is an oracle 10.2.0.4 with multiplexed redo log files on AIX.
I am creating an index on a "normal" table .. i execute "dbms_workload_repository.create_snapshot()" before and after the CREATE INDEX to get an equivalent timeframe for the AWR report.
After the index is built up (round about 9 GB) i perform an awrrpt.sql to get the AWR report.
And now take a look at these values from the AWR
                                                                   Avg
                                             %Time Total Wait    wait     Waits
Event                                 Waits -outs    Time (s)    (ms)      /txn
log file parallel write              10,019     .0         132      13      33.5
log file sync                           293     .7           4      15       1.0
......How can this be possible?
Regarding to the documentation
-> log file sync: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3120
Wait Time: The wait time includes the writing of the log buffer and the post.-> log file parallel write: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3104
Wait Time: Time it takes for the I/Os to complete. Even though redo records are written in parallel, the parallel write is not complete until the last I/O is on disk.This was also my understanding .. the "log file sync" wait time should be higher than the "log file parallel write" wait time, because of it includes the I/O and the response time to the user session.
I could accept it, if the values are close to each other (maybe round about 1 second in total) .. but the different between 132 seconds and 4 seconds is too noticeable.
Is the behavior of the log file sync/write different when performing a DDL like CREATE INDEX (maybe async .. like you can influence it with the initialization parameter COMMIT_WRITE??)?
Do you have any idea how these values come about?
Any thoughts/ideas are welcome.
Thanks and Regards

Thank you for Nice Idea.
In this case, How can we reduce "log file parallel write" and "log file sync" waited time?
CREATE INDEX with NOLOGGINGA NOLOGGING can help, can't it?Yes - if you create index nologging then you wouldn't be generating that 10GB of redo log, so the waits would disappear.
Two points on nologging, though:
<ul>
it's "only" an index, so you could always rebuild it in the event of media corruption, but if you had lots of indexes created nologging this might cause an unreasonable delay before the system was usable again - so you should decide on a fallback option, such as taking a new backup of the tablespace as soon as all the nologging operatons had completed.
If the database, or that tablespace, is in +"force logging"+ mode, the nologging will not work.
</ul>
Don't get too alarmed by the waits, though. My guess is that the +"log file sync"+ waits are mostly from other sessions, and since there aren't many of them the other sessions are probably not seeing a performance issue. The +"log file parallel write"+ waits are caused by your create index, but they are happeninng to lgwr in the background which is running concurrently with your session - so your session is not (directly) affected by them, so may not be seeing a performance issue.
The other sessions are seeing relatively high sync times because their log file syncs have to wait for one of the large writes that you have triggered to complete, and then the logwriter includes their (little) writes with your next (large) write.
There may be a performance impact, though, from the pure volume of I/O. Apart from the I/O to write the index you have LGWR writting (N copies) of the redo for the index and ARCH is reading and writing the completed log files caused by the index build. So the 9GB of index could easily be responsible for vastly more I/O than the initial 9GB.

Write to text file. Append to existing file. Create file if file doesn't exist.

Hi folks,
up to LabVIEW 7 there was a wonderful "Write to Text File" vi which allowed the option "Append to File". Now, in LabVIEW 8, this old vi is not longer supported anymore. Instead, I am suggested to use a new "Write to Text File" vi. This vi does not offer the option "Append to File" anymore. Rather it is proposed in the online help that one should use the "Set File Position" in order to append text to the file. This much less straightforward than the old solution. Furthermore, I miss an option which would create the complete path if it doesn't exist yet.
To summarize: Isn't there really any smart "Write to Text File" vi available which offers both the options "Append" and "Create path if file does not yet exist". Of course, I could write such a file on my own but I am sure that it is of such general interest that it already exist. In any situation, when a log file shall be written, the wanted vi would be ideal.
Thanks a lot,
Peter

Ray,
I know that the old vi is still available. See the screenshot which I attach to this message. What I am missing is an option "Create file or even complete path if file or path do not yet exist.". Is there any reason why NI doesn't provide neither this option nor a simple "Append to file" functionality in the new "Write to Text File" vi?
Regards,
Peter

Create directory and write files to it

i have installed tomcat 3.2.3 and am using ms access as databse.
through my jsp code i need to create random directories on the server and write files to it(need to have write access on the directories).
how do i do it?? thanx in advance.

You can include java.io in ur jsp page only using
<%@ page language="java" import="java.io.File %>
then u can create directories on the fly on the server using
mkdir(s) method of the FILE Object.
You will have to specify the path while creating a File object.
You will get the application's path using
application.getRealPath() method .... to wich u can append
whatever u will like...
Once u got the directory u can also create files using file object
Hope this is of any help...
Feel free toa sk if i could not satisfy u...

I have been trying to download photos. It keeps saying can't create file, please check permissions on destination folder. Ihave made sure I have set the permissions on read and write. What am I doing wrong?

Try this it worked for me Pat Willener gave it to me off the site :
I have not read all you wrote, so I may have missed some points. As I understand it, you installed FP 10 on IE7, but it won't play any Flash content?
Try this
download the FP uninstaller from http://www.adobe.com/go/tn_14157
close all browser windows, then run the uninstaller
download the offline ActivX installer for Internet Explorer from http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_ax.exe
close all browser windows, then run the installer

I'm trying to create an address spread sheet for my wedding invites and won't let me type zip codes that start w a zero "02904" it just automatically drops it "2904" how do u fix that?

The easiest fix is to format the receiving column as Text prior to making your entries.
Another way is to format as "Numeral System", Base: 10, Places: 5. This doesn't work so well if you need the 4 extra digits that some people like to use.
It's also possible to create a Custom Format, but it's rather more involved.
