LabVIEW

LabVIEW 2025 Q1 and Vision 2025 was release in January. I downloaded and installed both, but some problems are occurred.

Every LabVIEW’s control part contains a “part ID” field which determines its purpose and functionality in the control. For example, a digital numeric control contains two BigMultiCosmetic parts for the increment and decrement buttons; the part ID is what determines which one is which. The Parts Window in the control editor displays the part ID as the textual name for the part, though the actual number is only visible in Heap Peek.

It’s simple to explain what it does, but people often misunderstand whats behind of Wait (ms) Function and how this Function works. Most common misunderstanding is accuracy, often expected that the loop with with 1 ms Delay will operate at 1 kHz rate, but it does not.

While playing around with the Signal Processing Toolkit, I found in NI’s sources a funny method to detect which decimal separator is used in the operating system — simply perform a conversion of the string “1,23” to a double and compare it to the double constant “1.23”.

There are some “hidden” INI keys available in LabVIEW, which I often forgot
