Another pointer error. ponters are created by: int tablecount = 0; SQLWCHAR **tabledata, ***tablelist;
while (true) { sqlrc = SQLFetch(tableshstmt); if (sqlrc != SQL_SUCCESS && sqlrc != SQL_SUCCESS_WITH_INFO) break; if (m_dsnmaxcatnamelen) { SQLGetData(tableshstmt, 1, SQL_C_WCHAR, catname, sizeof(SQLWCHAR)*m_dsnmaxcatnamelen, NULL); catnameptr = new SQLWCHAR[wcslen(catname)+1]; wcscpy(catnameptr, catname); } else catnameptr = NULL; if (m_dsnmaxschemnamelen) { SQLGetData(tableshstmt, 2, SQL_C_WCHAR, schemname, sizeof(SQLWCHAR)*m_dsnmaxschemnamelen, NULL); schemnameptr = new SQLWCHAR[wcslen(schemname)+1]; wcscpy(schemnameptr, schemname); } else schemnameptr = NULL; SQLGetData(tableshstmt, 3, SQL_C_WCHAR, tablename, sizeof(SQLWCHAR)*m_dsnmaxtablenamelen, NULL); tablenameptr = new SQLWCHAR[wcslen(tablename)+1]; wcscpy(tablenameptr, tablename); tabledata = new SQLWCHAR *[3]; tabledata[0] = catnameptr; tabledata[1] = schemnameptr; tabledata[2] = tablenameptr; tablelist = m_tablelist; m_tablelist = new SQLWCHAR **[tablecount+1]; if (tablecount) memcpy(m_tablelist, tablelist, sizeof(SQLWCHAR**)*tablecount); m_tablelist[tablecount] = tabledata; if (tablelist) delete[] tablelist; tablecount++; } tablelist = m_tablelist; m_tablelist = new SQLWCHAR **[tablecount+1]; if (tablecount) memcpy(m_tablelist, tablelist, sizeof(SQLWCHAR**)*tablecount); m_tablelist[tablecount] = NULL; if (tablelist) delete[] tablelist; (m_tablelist is defined in header file: SQLWCHAR ***m_tablelist) Cleared by: SQLWCHAR ***tablelist; for (tablelist=m_tablelist; *tablelist; tablelist++) { if ((*tablelist)[0]) delete[] (*tablelist)[0]; if ((*tablelist)[1]) delete[] (*tablelist)[1]; delete[] (*tablelist)[2]; delete[] (*tablelist); } delete[] m_tablelist; When second lood try to delete pointer, system said that memory seems has been deleted. My pgsql test db has 21 tables, when connect to it with ODBC I always get this error. But a excel doc has 3 sheets(will be considered as 3 tables in ODBC driver) no error occur. ----------------------------------------------- Quan Zongliang quanzongli...@gmail.com -- Sent via pgadmin-support mailing list (pgadmin-support@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgadmin-support
