rc = sqlite3_prepare(pDB,MbcsToUtf8(c2),-1/*strSql.GetLength()*/, &pstmt, &errMsg);

CStringA CDataBaseHelper::getSqliteString( const unsigned char* chData ) { int len = MultiByteToWideChar(CP_UTF8, 0, (LPCSTR)chData, -1, NULL, 0); wchar_t* pUnicode = newwchar_t[len+1]; memset(pUnicode,0,(len+1)*sizeof(wchar_t)); MultiByteToWideChar(CP_UTF8, 0,(LPCSTR)chData, -1, (LPWSTR)pUnicode, len); wstring strUnicode = ( wchar_t* )pUnicode; delete pUnicode; CStringA strData(strUnicode.c_str()); return strData; }CStringA CDataBaseHelper::MbcsToUtf8( const char *file ) { CStringA str; WCHAR*pwchar=0; CHAR*pchar=0; int len=0; int codepage = AreFileApisANSI() ?
