interface .dll - can I involve some C++ code

Good day,

I got some .dll from a supplier and want to use it to calculate some outputs. Cannot upload the .dll for proprietory information.

There is some Excel addin that uses the .dll, but nothing for labview. I got some C++ example how to use the .dll

pretty much need to create some objett, then a pointer, then some strcopy stuff

I tried tools, import shshared library (,dll) but no luck, it only found some functions to return the variables I can get calculated plus their units, such as motor power in kW. So as such it works, but I cannot actually get the .dll to calculate the motor power for me

thanks!
