here is a part of the code where the error appears
[...snipped irrelevant code, please do that yourself next time...]
CQueAlert(int AlertID, int LockID, CString AlertDesc = "");
here it points to
Two things:
1. CString is TCHAR-based, hence the suggestion from Mark to use a TCHAR
string literal _T("").
2. You can use an empty CString object:
function( ..., CString desc = CString());
or alternatively use two overloaded functions:
function( ...);
function( ..., CString desc);
virtual ~CQueAlert() {};
^ no.
This is not syntactically wrong because it is inside a class definition, but
it is logically wrong. Further, you don't need to provide a destructor if
the compiler-provided one works for you.
