VS2015 building error messagebox

问题

Some of you might know why I get these errors, I am scripting in c++ at the moment and I can't figure out why I get these.

argument of type "const wchar_t *" is incompatible with parameter of type "LPCSTR"

argument of type "wchar_t *" is incompatible with parameter of type "LPSTR"

'int MessageBoxA(HWND,LPCSTR,LPCSTR,UINT)': cannot convert argument 2 from 'const wchar_t *' to 'LPCSTR'

'DWORD GetModuleFileNameA(HMODULE,LPSTR,DWORD)': cannot convert argument 2 from 'wchar_t [260]' to 'LPSTR'

I already tried disabling the character set, I tried using unicode and I tried using multi byte and I tried not set.

I have highlighted the errors, and deleted some code to prevent leechers. The words with ** between them are errors.

回答1:

You are using wchar_t, so instead of macros like GetModuleFileName and MessageBox, you should use functions that explicitly use wide characters such as GetModuleFileNameW and MessageBoxW.
