这条语句在那里写？设置过虑条件好像是：
ret;
MSG_FILTER_STRUCT Filter;
CMN_ERROR Error;
memset( &Filter, 0, sizeof( MSG_FILTER_STRUCT ) );
strcpy( Filter.szFilterName, "Control1");
Filter.dwFilter = MSG_FILTER_DATE_FROM MSG_FILTER_DATE_TO;
Filter.st[0].wYear=2005;
Filter.st[0].wMonth=5;
Filter.st[0].wDay=7;
Filter.st[1].wYear=2005;
Filter.st[1].wMonth=5;
Filter.st[1].wDay=7;
ret = AXC_SetFilter("NewPdl2","Control1",&Filter,&Error);
