LabVIEW
Help Me On These Labview Programmings...
LabVIEW ships with a huge collection of example programs.
In LabVIEW, go to "Help...Find examples". In theexample finder, I would start with the section "Fundamentals...File Input and Output" for your current problems. See how far you get. Maybe you should also do a tutorial to become familiar with some programming concepts.
Post again if you get stuck 😉
Hey thanks!
But...Im stuck with something now..
I have already tried to do my data-logging that I have acquired the signal from the DAQ board and then write it to a file and it is successful. However, when I want to read it back, I cannot access to the same file that I write in. It leads me to the file path, named file dialog. So how??
And i hope it makes sense..
Your datalog types are not matched.
First, you also need to wire the datalog type when you open the file in the writer (just create a constant on the cluster leading to the write node, place it next to the file open, and wire it to the type input.)
You need to read it as the same type!
- You are writing records as a cluster containing a cluster of 2 strings and a 2D DBL array.
- You are trying to read it as a cluster containing a simple string and a 1D SGL array.
You cannot write it as one thing, then read it as something else! You need to wire the same type to the type input in your reader.
(Since in the writer you are denying writing, you need to open the same file read-only in the reader if you want to run both at the same time.)
Attached is a 1 minute modification, please go from there. It's still pretty ugly, but actually works. 😉
I hope these tips will help you.

Did you select the correct file path before running the program? 😉
(If you want that the program asks you for the file name with a file dialog, replace your path control with the "file dialog" from the advanced file I/o palette.)
