Non-ActiveX COM Interface?

[YohanShminge]

Hi Everyone,

I'm wondering if LabVIEW can interface with a COM DLL that doesn't have a specific ActiveX interface.  It works within MATLAB using the following line of code:

     h = actxserver('RPI_IOBoard.IOBoard')

However, when I try to use LabVIEW's "Automation Open" block, this COM component isn't listed in the type libraries dropdown (it is registered on this computer).  When I browse to the actual DLL LabVIEW says, "The selected file is not a .NET assembly, type library, or automation executable."  Am I going about this the wrong way?

Thanks!
