Derive from CString, but access CString buffer (VS2005)
Hi,
I'm copying code from a VC++ 6.0 project to VS 2005. The code has a string class derived from CString in which some members of CString are accessed (m_pchData, GetData()). The code compiles in VC6 but not in VS2005. I need to be able to do:
class CStringEx : CString
{
public NewFunctionEx()
{
// Access private members of base CString
char* inside_buffer = m_pchData;
// OR
char* inside_buffer = GetData();
}
};
It's just the syntax is tricky since it's a template class and I guess the members are private now...?

What is the error which you are getting while compiling it in vs2005?

Yeah, when I used GetBuffer() I would get
C2663: 'ATL::CSimpleStringT<BaseT
But today I found I could get over it with ((CString*)this)->GetBuffe
We'll see if it works, but before I can compile, I need to solve one more error. The code I'm using calls a method AllocCopy() that evidently allocates a string and copies a substring from an existing string to it. There is no definition for this method anywhere in the project, so I'm wondering if AllocCopy was ever a CString method?

It seems it was a protected member function in CString
