#include <windows.h>

enum CLASS_ENUM { SS_AUTO, SS_SIMPLE, SS_SERIES };


int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
}

main.cpp(2) : error C2059: syntax error : 'constant'
main.cpp(2) : error C2143: syntax error : missing ';' before '}'
main.cpp(2) : error C2143: syntax error : missing ';' before '}'

如果把enum放到window.h之前就没问题
