I'd assume you mean a CString* rather then a String*. If you really do mean String, can you reference the header file it is declared in?

In MFC 8.0 CString is a typedef for CStringT, which inherits from CSimpleStringT.

The following are references for the methods and operator allowing direct access to the string contained in the CSimpleStringT, and thus the CString:

The list of methods for CSimpleStringT can be found at:

1.
CString *pStr; // string must be initialized!
const char *mychar = (const char*)LPCTSTR(*pStr);

2.
CString *pStr; // string must be initialized!
char *mychar = new char[(MAX_PATH + 1) * sizeof(TCHAR)];
memset(mychar, 0, (MAX_PATH + 1) * sizeof(TCHAR));
memcpy(mychar, (const char*)LPCTSTR(*pStr), pStr->getLength() * sizeof(TCHAR));
