Write to measurement file, adding column name in text file.

[Mrcn]

Hello,

Is it possible to add own column name for a text file using Write to measurement file function?

In the created file I have three different columns (I want to name them Time/Voltage/Date&Time).

Maby I should choose different write option like write to spreadsheet?

Write to spreadsheet is common,  format into file allows a lot of flexability (especially with timestamps.)  Lately, I've been very happy with the TDMS file functions and features you might want to peek into the example finder and look that over and sell yourself on the flexibility to veiw while collecting data.

I've done a little research but I can't find out if I use write to spreadsheet function can I add push button so the file register data only when the button is pushed?

Of course. That's a trivial exercise in LabVIEW. Do you know about event structures or case statements? Have you taken any of the numerous free tutorials?

[Mrcn]

Ohh, well stupid I. I was so focused on Write to measurement file that I forgot abut the rest. I think I need coffee break right now.

Sorry for double post.

I'm facing a problem with data display, I saved it as .csv format.

The problem is that the columns should be separated but they are not. Why ?

You are going to have to post some actual code if you want us to help here.  Otherwise it is a complete shot in the dark.  Posting an example CSV file of what you have and what you want would also be beneficial.

Attach an image of the block diagram and text file, please.

Hi mrcn,

place a probe on the wire after ConcatenateStrings function and you will see why this happens…

It's a bad idea to put the delimiter char in your strings on your own (as you did with the column headers) and it's a bad idea to concatenate strings which should build an array of strings…

Using ReplaceArraySubset doesn't provide any advantage here…
