Why do I get this Error.. when this code was copied from MSDN why do they write something that doesn't work?

||=== Build: Debug in ListView (compiler: GNU GCC Compiler) ===|
|In function 'BOOL InitListViewColumns(HWND)':|
|32|error: cannot convert 'WCHAR [256] {aka wchar_t [256]}' to 'LPSTR {aka char*}' in assignment|
|40|error: invalid conversion from 'int' to 'LPSTR {aka char*}' [-fpermissive]|
|3900|note: initializing argument 3 of 'int LoadStringA(HINSTANCE, UINT, LPSTR, int)'|
||=== Build failed: 3 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|
