wince5.0，eVC4.0下CString到char，char ANSI到char Unicode转换

//Unicode转为ASCII码
	DWORD dwNum = WideCharToMultiByte(CP_OEMCP,NULL,m_editName.GetBuffer(m_editName.GetLength()),-1,NULL,0,NULL,FALSE);
	m_editName.ReleaseBuffer();
	char *strAnsi;
	strAnsi = (char *)malloc(sizeof(char)*dwNum);
	WideCharToMultiByte (CP_OEMCP,NULL,m_editName.GetBuffer(m_editName.GetLength()),-1,strAnsi,dwNum,NULL,FALSE);
	m_editName.ReleaseBuffer();

TCHAR *strUni;
//Unicode转为ASCII码
DWORD dwNum = MultiByteToWideChar(CP_OEMCP,NULL,arrName[i],-1,NULL,0);
strUni = (TCHAR *)malloc(sizeof(TCHAR)*dwNum);
MultiByteToWideChar (CP_OEMCP,NULL,arrName[i],-1,strUni,dwNum);
