CString str = "Hello World!"; TCHAR* buffer = str.GetBuffer(str.GetLength()); _tcscpy_s(buffer, str.GetLength(), _T("Goodbye World!")); str.ReleaseBuffer();
CString str = "Lorem ipsum dolor sit amet"; char* buffer = (char*) str.GetBuffer(str.GetLength() + 1); str.ReleaseBuffer(); std::cout << buffer;This code creates a CString object with the value "Lorem ipsum dolor sit amet". It then gets a pointer to a buffer with enough space to hold the string plus one extra byte (to store the null terminator). It then releases the buffer and prints the contents of the buffer to the console. This function is part of the MFC (Microsoft Foundation Class) library.
