问题 When I use this code if (GetKeyNameText(Key << 16, NameBuffer, 127)) { KeyName = NameBuffer; GoodKeyName = true; } I get the following error C2664 'int GetKeyNameTextW(LONG,LPWSTR,int)': cannot convert argument 2 from 'char [128]' to 'LPWSTR' The NameBuffer says this: Error: argument of type "char*" is incompatible with parameter of type "LPWSTR" Any tips? 回答1: You have UNICODE defined, which means all your functions and TCHAR and LPTSTR are defaulting to wide characters ( wchar_t ).

问题 I'm taking a c++ beginner's distance class and can't solve this compile error.

The error codes I get are: Error E0167 argument of type "const char " is incompatible with parameter of type "char Error C2664 'void Hello
