CSTRING轉char *\\char *轉CSTRING 亂碼問題

CString st=_T("123");
int nLength = st.GetLength();
int nBytes = WideCharToMultiByte(CP_ACP,0,st,nLength,NULL,0,NULL,NULL);
char* path1 = new char[ nBytes + 1];
memset(path1,0,nLength + 1);
WideCharToMultiByte(CP_OEMCP, 0, st, nLength, path1, nBytes, NULL, NULL);
path1[nBytes] = 0;



cstring m_edit;

m_Edit.Format(_T("%s"),CStringW(char *));
