In my VI when I want to collect and save data to CSV , I use curremt date and time for the file name but I would like to also use a popup message and ask if the operator wants to add a comment to the file name ( just a string ) . Could u plz help me how can I implement it in LabVIEW
thanks

There's an express VI for an input dialog window. From there, just use Concatinate String to build up your file name and then Build Path to add the file name to the folder path.

Unlike Tim I don't really care for the polling that goes on in the Express vi. And, I really hate saving a vi "modal" so I keep a few of these around.

Heck, I didn't realize the Express VI polled the buttons. I was just trying to keep it simple for the OP. I just started hating Express VIs even more.

They used to have to since there used to be versions of LabVIEW that did not have events And, I suppose they still have to for backwards compatability.

I call BS. Express VIs are newer than Event Structures by at least 1 version (Events in 6.0, Express VIs in 7Express). I think what was missing was the scripting capability to manipulate the event structure and they haven't revisited the express VIs for a while.

Not that its that big of a deal but Events weren't in all versions until 2012. How would a student play with the express vis? Sure your 6.0 Pro version had events....
