Calling external code from different languages is great feature of LabVIEW. In general you can wrap almost anything into DLL, then call it by Call Library Function Node. This time we will mix Rust code with LabVIEW.

This is a question, raised again and again on the forums about third-party DLLs: “…whatever I do I cannot get the library to work in LabVIEW. I get the error “The library for this node cannot be found or cannot be loaded….”. Below short “check list” with some explanations.

Some useful variables like %PROGRAMFILES% or %USERPROFILE%, which I often forgot.

Two ways, how to check if a binary is 32 or 64 bit on Windows. One is “official”, using dumbpin and another one is “funny” using … Notepad.

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”.

When I hold Left Alt + Tab, I am still able to select my desired window by tabbing, however when I release Alt, nothing happens. It still stuck at the small window selecting thing, I have to manually click on or hit ENTER to switch to the desired window instead of just releasing key. Looks like left Alt acts as right Alt. And the Solution is to add DWORD Value AltTabSettings and set it to 1 to the Registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

Two command lines which I often forgot and googling again and again. If you have dynamic link library, but haven’t according *.lib file, then use

dumpbin /EXPORTS yourfile.dll > yourfile.exports
lib /def:yourfile.def /out:yourfile.lib

Technical validation of the DICONDE Files is important compliance step to be sure that the PACS System is compliant to DICONDE Standard. Below the instruction how to validate DICONDE Files.

The AIPD image format is an internal, proprietary National Instruments format. It can normally be opened in NI software like Vision Assistant, but it can also be opened in ImageJ.

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