C# sub_find_devices

[nebruin]

I've been looking through the documentation for the Sub-20 device, and I see a function called sub_find_devices listed in the manual, but I can't seem to find this anywhere in the C# assemblies. Is this function exposed in the C# libraries?

Thanks.

Hi,
The method corresponding to the sub_find_devices function is "GetNext", see the sub20net document for more information. The document conains a VB example which shows usage of this method

Thanks for the reply, but in the C# library that function is not exposed. Here is the output from the metadata from the assembly.

There are no GetNext functions.

Thanks.

Hi Nebruin,
The assembly actually exposes two classes: Sub20 and Sub20Enum. The GetNext method belongs to the Sub20Enum class. See the sub20.NET document for more information. The section related to the GetNext method includes a VB.NET sample code which shows how to find a board by serial number
