How can I save multiple data coming in from my data string

I am a newbie at labview. I have a scale connected to my RS 232 and made a VI to display the changing scale. I am trying to save the multiple changes as my weight varies but have been only able to save the last value. Is there a simple way to save all the values I see in my VI to a file for later plotting? I have done one before using indexing but the case this time is that I am receiving a character string and not a numeric array. Any examples or advice would be great!!! Thanks
Gerald

Hi Gerald,
What you need to do is write to a file continuously, i.e. after each point you collect. You can do so by opening a new/existing file, write to it inside your while loop, and close it once you are done collecting and writing data points, i.e. outside the loop.
I believe the following example is a good demonstration of that operation.
Best of luck,
AG

How can I save multiple separate edited images from one original file?

I shoot NEF raw images and am getting used to the way LR5 editing works without altering the file in any way. Now I wonder how I can create multiple edited images this way.

Thank you, that was spot on. It will help a great deal right now as I am taking multiple crops from shots of the ocean looking for something striking.
I doesn't seem to matter if I take a copy while editing or before I start editing, I can always reset the original and start again.
Is it possible to rename the copy? I had a look around here and in LR Help but rename doesn't come together with virtual copy.

How can I save multiple titles under the same DVD?

I use HandBrake to rip DVD's into iTunes. How can I save multiple titles under the same DVD? For instance, I have a Jimi Hendrix documentary that comes with special features, such as concert performances. I would like to have the main feature and the special features saved in my iTunes under the same title, perhaps as different 'tracks' (kind of like how different songs can be saved under the same album).
Is there a way for me to do this, or am I chasing phantoms?

*This response is for iPhoto 11 (v9). If you're using an earlier version, please post back and let us know. Troubleshooting steps are not the same for different versions. To find out which iPhoto you have: iPhoto Menu -> About iPhoto)*
Duplicate the photo first. (Photos -> Duplicate). This means that you will have multiple copies of the master as well as the edited version.
If you use versions like this often and wish to have only one master then you can do this with Aperture.

How can I save my data and the date,the time into the same file when I run this VI at different times?

I use a translation stage for the experiment.For each user in the lab the stage position (to start an experiment) is different.I defined one end of the stage as zero. I want to save the position , date and time of the stage with respect to zero.I want all these in one file, nd everytime I run it it should save to the same file, like this:
2/12/03 16:04 13567
2/13/03 10:15 35678
So I will track the position from day to day.If naybody helps, I appreciate it.Thanks.

Hi,
I know the function "write to spreadsheet file.vi"
can append the data
to file. You can use the "concatenate strings" to display the date,
time as well as data... Hope this help.

How can i save the data from the Oracle database to my local directory

How can i save the data from the Oracle database to my local directory instead Of saving the data file to the Directory created on the Oracle Server ?
I require to design the Procedure which will pull the data from various tables and needs to store the data in the Client's local directory.

Since SQL*PLUS runs on the client, you can use SQL*PLUS to spool data to your local drive.
You could also use the database to write a a specified drive where all users have access to (mapped network drive, e.g.). I wouldn't recommend doing it that way, but it is sometimes useful when the files are created in some nightly batch run.

Solved!
Go to Solution.

Hi,
If your data is in an array, the easiest way is to use the ArrayToFile function.
It automatically creates a file and puts your data in it according to the format you provide.
If you have individual samples that you need to write once in a while, you can either collect them into an array and then use ArrayToFile or open a file with fopen and write them as they are acquired with fwrite.
Hope this helps,

HT1320 how can i save me data stored on a non responding ipod classic and says you need to format before using it?

how can i save me data stored on a non responding ipod classic and says you need to format before using it?
in another way : how can i save my date stored on my classic iPOD as a external hard .... when that msgs appears .... volume doesn't contain a recognized file system , make sure the file system is loaded .... then , you need to format ??? can anyone help ?

It sounds like the iPod's storage has data corruption. You may be able to treat it like an external drive and use data recovery software on it, but it probably won't work because the system is telling you that the drive needs to be formatted before it is recognized.
If the problem is data corruption and there is no hardware-related problem on the iPod's hard drive, a Restore should fix the problem. But this will obviously erase the iPod's hard drive.

How can I save the .mp4 files downloaded from internet to ipad memory so that I don't have to download everytime to view them again

How can I save the .mp4 files downloaded from internet to ipad memory so that I don't have to download everytime to view them again. Also they might remove them from internet so I can't rely on the bookmark to them.

I'm trying to send home movies to my 10 year old nephew who lives across the country. He doesn't have a computer. He has an iPod touch. His parents have computers. But I don't want everything I ever try to have him do result in "you need your parent's computer for this." It's getting really embarrassing. I have converted my family over to Apple computers but now they want to buy iPhones, iPads, and iPods even though I tell them to go Android. It took a decade to convert them away from windows now I'm trying to keep them away from these freedom limited iOS devices and they won't listen. Then it becomes my responsibility to make their iPads print to their fancy pre-airprint color laser jet printers, get home movies onto them, and countless other things. It's driving me nuts.
I have converted these files to a format that the iOS devices will play directly off of dropbox. Now, how do I get the infernal devices to save it instead of play it?

How can I save multiple links using the "save link as" function?

I'm trying to save about 300 pdf files. The link to each one is listed ona website. To save each one I'm right clicking on the link, selecting "save link as" and repeat.
How can I select multiple links and save them?

Actually you can save multiple page pdf's in elements.
Try something like this:
(This is easier if you have the project bin open)
1. Select the first page
2. Right click on that page in the project bin and choose Add Blank Page or as many pages as you need.
3. Use the move tool and drag your pages down into the blank pages in the project bin
4 Then File>Save As>Acrobat.PDF

Data still in mical, but was deleted via icloud in ical. How can i save my data?

still in 5.1.1, and I had general data in ical saved on my iphone but not in the icloud (which was a mistake, I didn´t notice). As I syncronised the ical data with the icloud, these general data were deleted. I guess they are still in mical, which I use, but I don´t want to open mical as it would immedeately syncronise with ical and the general data would be lost forever. Does anyone have a solution for the problem? How can I retrieve my data?
Thanks in advance
