Creating Numbers

[ASCologne]

Hallo,

I want to save a lot of measurements in one file each. The name should be "mess0001.txt", "mess0002.txt" etc.

For that I need to "fill up" the number of measurement with zeros. My way looks like this:

13 -> 31 -> 31000 -> 3100 -> 0013

(rotating, filling up, cutting of, rotating)

Does anybody of you know an easier and shorter way?

It's easy with the Format Into String function. In your case, if you want a width of 4 and padded with zeroes, the format string would be "mess%04d.txt" (without the quotes). If you right click the function and select Edit Format String, you will get a dialog box that will help you create the format string. There is also a lot more information on format string options in the on-line help.

I forgot something:

I am using LabVIEW 6.1. If you are using LabVIEW 7.0, please convert the VI, thanks.

I did it that way:

array to string -> string lenght to case structure -> depending to the
case use Concatenate Strings with 0, 1, 2 or 3 zeros.

But maybe it is not esier then your way,

Here's basically the suggestion of Dennis as a LV6.1 example.

Hi,

My problem is to create file names continuously, so that I can save different measurement files captured from my instrument.

The problem looks like this:

1. I am looping my instrument many times, say 500 times.

2. During each iteration, one measurement file is returned by instrument.

3. Now to save file I have to give some filename.

Also, the care should be taken so that there must not be any duplicate file names.(I am using Labviwe8.5)

As I am new to labview, So can anyone help me?

Thanks.

Hi Piscesking,

the example of altenbach shows exactly what you need. You said you are looping, so connect your loop iteration counter to the example from altenbach. With the created filename you can build a path and save your file. With this method duplicates are impossible, because with each iteration you get a new filename.

Thanks, Let me try it out.

Hi,

As asked earlier, I am using "for" loop to repeat the setup a number of times.

Now, as suggested,

Let N=20 (number of loops to be executed), then i=19, 

Now either I connect 'i' or 'N' with the example provided earlier, resultant is only one filename corresponding to respective number given.

or

I think I am not able to get the value of the counter. Can you help me out.

Thanks.

i=19 is only true for the last iteration of the FOR loop. In the first iteration, i=0, second iteration i=1, etc. giving you a new value for each iteration that you can use to construct a unique file name with every iteration.
