Implementation problem with a .NET dll


Recommended Posts

Dear LabVIEW User,

I have to implement some VisualBasic.NET dlls in LabVIEW 8.21. Unfortunately LV8.21 has

a problem to show all methods, only some of them are available. Within LabVIEW 8.6 I can see

and use all methods. Maybe there is a way how the public interface in a .NET DLL have to be designed for the use with LV8.21.

The .NET programmer told me, that there is an influence if generic dictionaries are be used …

I am curries to get your response… thanks… and warm greetings from Germany…

Hello Norbert,

The following is probably not going to help, so, in advanced, apologies for that.

I'm using LV 8.20, and have successfully written wrappers to .NET assemblies.

If I can suggest something: wire the error clusters (ins and outs) and run it in debug mode.

The other thing to try is to re-wire the constructor node on each VI; In short, re-select the .NET assembly.

While I was working on my project, my vendor kept providing updates to the .NET assemblies I was using, and in one instance I saw an error where I could not see properties... and the reason for that was that I had forgotten to link my VI to the newer .NET provided.

Cheers,

edp
