How to solve these compilation errors

[realife]

I encountered the following error message during the compilation process in a simple MFC (VS2022) program. May I ask how to solve it?
1、Error C2061: Syntax error: identifier "EPointerStyle"
Error C2061: Syntax error: identifier "EBarStyle"
Error C2061: Syntax error: identifier "ITeePicture"

2、Error C2065: 'AStyle': Undeclared identifier
Error C2065: 'BarStyle': Undeclared identifier

3、Error C2275: 'Picture': Expected an expression instead of a type
