这个例子示范了怎样将一个Vega Prime窗口加入到MFC程序文件，全部的Vega Prime代码放在vp_mfcView.cpp.里面。另外的文件是MFC 应用向导自动产生。-This sample illustrates how to add a Vega Prime window to an MFC app.　All of the Vega Prime specific code is in vp_mfcView.cpp.　The other files were auto-generated by the MFC AppWizard.　Search vp_mfcView.cpp for “Vega Prime” to see all of the code additions.　Before you start DevStudio, make sure the environment variable VUNOTIFY_CREATE_CONSOLE is set.　When this environment variable is set, Vega Prime will create a console.　The console is helpful for catching debug messages.　To remove the console window, unset VUNOTIFY_CREATE_CONSOLE
