I’m working with some DLL library in order to integrate a measurment instrument (a power meeter) on Matlab. I’m using the 2021 version of Matlab and I used the following code to load the DLL library: (note that the library was given to me from the company who sell me the power meeter).
clear all;
%Load the library
NET.addAssembly(‘C:Program Files (x86)Microsoft.NETPrimary Interop AssembliesThorlabs.TLPM_64.Interop.dll’);
import Thorlabs.TLPM_64.Interop.*;
%Create a dummy TLPM object to check for compatible devices.
handle = System.IntPtr(0);
device = TLPM(handle);
%Search the device
[~,deviceCount] = device.findRsrc();
When I run it, Matlab load the library but when I try to use the function "findRsrc" I get the following error:
Found on line 1324 of input from line 1065 of file C:\Program Files\IVI Foundation\VISA\Win64\Include\TLPM.h

Type ‘intViStatus__fastcall’ was not found. Defaulting to type error.

I tried many things ans then, by seraching online, I saw that the problem is may due to the compiler version. Since I have also 2019 and 2020 matlab licenes I tried on both the version and i found out that it works on the 2019 version of Matlab.
So my questions is: Do you have any ideaa what could be the problem on the newest version? there is something that I can do to make it work on the 2020/2021 version?I’m working with some DLL library in order to integrate a measurment instrument (a power meeter) on Matlab.
