<DIV>HI!</DIV>
<DIV><BR>I am download omniORB-4.0.7-win32-vc7.zip,<BR>I am using omniORB_4.0.7 on Win2000 (MSVC++7.1) platforms,<BR>and the echo examples work fine .</DIV>
<DIV>Now I use data sequence,but have the problem :</DIV>
<DIV><BR>//----------IDL---------</DIV>
<DIV>struct NetDataItem<BR>{<BR> long id;<BR> string name;<BR>};</DIV>
<DIV>typedef sequence<NetDataItem> DataArray; <BR>typedef sequence<long> DataLongArray;</DIV>
<DIV>interface QDataSeq<BR>{<BR> DataArray QueryDatas(); <BR> DataLongArray QueryLongData(); <BR>};</DIV>
<DIV><BR>//---------server code--------------</DIV>
<DIV>// return struct data Sequence<BR>DataArray* QDataSeq_i::QueryDatas(){<BR> int cnt =100;<BR> DataArray_var datas = new DataArray((CORBA::Long)cnt);<BR> datas->length(cnt);<BR> for (int i =0;i< cnt; ++i)<BR> {<BR> datas[i].id = (CORBA::Long)(i+1);<BR> datas[i].name = CORBA::string_dup("aaaa"); // is OK??<BR> }<BR> std::cout << "OK" << endl;<BR> return datas._retn();<BR>}</DIV>
<DIV>// return long Sequence<BR>DataArray* QDataSeq_i::QueryLongData(){<BR> int cnt =100;<BR> DataLongArray_var datas = new DataLongArray((CORBA::Long)cnt);<BR> datas->length(cnt);<BR> for (int i =0;i< cnt; ++i)<BR> {<BR> datas[i] = (CORBA::Long)(i+1);<BR> }<BR> std::cout << "OK" << endl;<BR> return datas._retn();<BR>}</DIV>
<DIV><BR>//-----------client code-----------------------</DIV>
<DIV>this arises some exception of free sequence. why?</DIV>
<DIV>//query struct data Sequence , use _var<BR>void queryData(QDataSeq_ptr e)<BR>{<BR> DataArray_var dest = e->QuearyDatas();<BR> int len = pdest->length();<BR> std::cerr << "query sequence size ：" << len << endl;<BR> //do something<BR>}<BR>/* use delete sequence ptr<BR>void queryData(QDataSeq_ptr e)<BR>{<BR> DataArray* pdest = e->QuearyDatas();<BR> int len = pdest->length();<BR> std::cerr << "query sequence size ：" << len << endl;</DIV>
<DIV> //pdest->release(); <BR> delete pdest; // arise some exception. <BR> //If this isn't used 'delete' , it have memory leak,but run OK.<BR>}<BR>*/</DIV>
<DIV><BR>//query long Sequence. It is work fine and not have memory leak. <BR>void queryData(QDataSeq_ptr e)<BR>{<BR> DataArray_var dest = e->QuearyDatas();<BR> int len = pdest->length();<BR> std::cerr << "query sequence size ：" << len << endl;<BR> //do something<BR>}</DIV>
<DIV>====================================<BR>Get a list of NetDataItem and display it, ERROR IN THE CLIENT.<BR>but Get a list of long ,it work fine.<BR>why?</DIV>
<DIV>Help me! <BR>How to fine use sequence of struct in the client and server?</DIV>
