Hi

I willing to make vendor command in windows application. 

And i can find two dll files 1. Cyapi.dll 2. Cyusb.dll. 

What is different between cyapi.dll and cyusb.dll to make vendor command using c++?

Hi,

If you are going to make an application with C++ then you need to use CyAPI.lib. CyAPI.lib provides a simple, powerful C++ programming interface to USB devices. For more details on CyAPI.lib, please refer to the attached CyAPI.pdf.

If you are going to make an application with C# then you need to use CyUSB.dll. CyUSB.dll is a managed Microsoft .NET class library. Because CyUSB.dll is a managed .NET library, its classes and methods can be accessed from any of
the Microsoft Visual Stuido.NET managed languages such as Visual Basic.NET, C#, Visual J# and
managed C++. For more details, please refer to the attached CyUSB.NET.pdf

Thanks,
