Can I use any method to allocate /deallocate memory other than new/
delete operators? Actually the problem is while using delete operator
in my ".sqc" files the application crashes. It seems the memory
location is locked by DB and so it throws an 'unhandled exception'.
Following is the code snippet from my application and now i dont wanna
touch the basic design.

Code Snippet:
//----------------------------------------------------------------------------
// SQLFetchfun() - Fetch the next record pointing by the cursor.
//-----------------------------------------------------------------------------

long SQLfunFetch(fun *afun)
{
#if 0
   EXEC SQL BEGIN DECLARE SECTION;
    char hv_fnName[31];
   char hv_fnID[16];
   char hv_area[11];
   short *hv_fnCrType;
   char hv_creatorName[21];
   char hv_creatorID[11];
   EXEC SQL END DECLARE SECTION;
#else
/* char *hv_fnName; //Comments : Here comment the
earlier code & intialize all the
   char *hv_fnID; // pointer variables with "new"
declaration.
   char *hv_area;
   short *hv_fnCrType;
   char *hv_creatorName;
   char *hv_creatorID;*/

   char *hv_fnName = new char[sizeof(afun-

fnName)*sizeof(TCHAR)]; //Comments : use sizeof var name * sizeof

TCHAR
   char *hv_fnID = new char[sizeof(afun->fnID)*sizeof(TCHAR)];
   char *hv_area = new char[sizeof(afun->area)*sizeof(TCHAR)];
   short *hv_fnCrType;
   char *hv_creatorName = new char[sizeof(afun-

creatorName)*sizeof(TCHAR)];

char *hv_creatorID = new char[sizeof(afun-

creatorID)*sizeof(TCHAR)];

#endif

   EXEC SQL SET SQLCA "gpSqlca";

/* hv_fnName = cfun->fnName; //Comments : Here comment the
earlier code of intialization & use Convertto_mbcs
   hv_fnID = cfun->fnID; //
   hv_area = cfun->area;
   hv_fnCrType = &cfun->fnCrType;
   hv_creatorName = cfun->creatorName;

Convertto_mbcs(afun->fnName,hv_fnName);

Convertto_mbcs(afun->creatorName,hv_creatorName);
Convertto_mbcs(afun->creatorID,hv_creatorID);
hv_fnCrType = &afun->fnCrType;

    EXEC SQL FETCH RELATIVE 1 funCursor
        INTO :hv_fnName,
           :hv_fnID,
              :hv_area,
           :hv_fnCrType,
           :hv_creatorName,
           :hv_creatorID; //Comments : After the SQL statement is
finished convert the vaules from
                    // host variable to widechar & fill the unicode
structure

Convertto_widechar(afun->fnName,hv_fnName);
Convertto_widechar(afun->fnID,hv_fnID);
Convertto_widechar(afun->area,hv_area);
Convertto_widechar(afun->creatorName,hv_creatorName);
Convertto_widechar(afun->creatorID,hv_creatorID);

delete hv_fnName; //Comments : Delete the
variables earlier assigned with "new"
delete hv_fnID;
delete hv_area;
delete hv_creatorID;
delete hv_creatorName;

   return ( gpSqlca->sqlcode );
