VST plugs-in Effect

I am sorry that what I want to know is that when we develop the VST Effect with the tool of
Audacity2.1.0 , Microsoft Visual Studio 2012 and VST2.4, when we press the “Apply” button
debuging with Microsoft Visual Studio 2012 , we can not know the “Apply” button called which
functions in VST2.4, so the VST Effect was not used.

Your question has nothing to do with Nyquist.
