Loading different DLL

[jyang72211]

I want to do the following.  Not sure what's the best way to go about it.  I have 2 .NET DLL that my LabVIEW program uses.  The program determines which DLL to use by looking at the value of a boolean.  My questions.

1. How do I use which DLL to load at run time?

2. Some labview code is only applicable to one DLL and not the other, would there be an error?

Personally I'd create two separate LabVIEW classes which mirror the .NET components. At run-time you load the desired class, which then loads the corresponding .NET component. I don't think there's any way you can avoid duplicating code for the two different DLLs, although I haven't tested to see whether LabVIEW can handle .NET class inheritance (assuming that your two .NET components either inherit from the same class or implement the same interface). I also don't know how you could attempt to call a non-existent method on a .NET class in LabVIEW, I think you'll get an error at edit-time.
