Is it possible to convert from string to variant?

[mattias@hv]

Hi!

I would like to convert a text string to variant. I'm doing this because I would like to merge a couple of signals and then save all the signals in a lvm-file. Could someone please explain how to convert from text to variant, is it possible?

Thanks in advance!

Regards,

Mattias

Couldn't you just use the Merge Signals.vi and not worry about variants?

Whats in the string data? Maybe you can convert it to a number or array then use to the Convert to DDT function

What you are attempting to do is possible, but might not give you the results you expect.  All you need to do is convert your string to an array of U8s using the String to Byte Array conversion primitive.  In the file, you will get a single character per line of the file expressed as the ASCII code.  When you read it, convert to U8s, then use Byte Array to String to get your string back.

You may also want to read up on LVM files.  There are several places to put strings that work a little better than this.

Rather than trying to cram the text into a signal format, you could just put it in the Comment terminal of your Write to Measurement File.

Thanks for your good advices. I have now connected my string to the comment terminal and it works fine.
