[Firebird-odbc-devel] VFP and large VARCHARS

[<sc...@de...>]

Hello ,

I found a new problem when using VFP with "oversized" varchars. I 
tried a
VARCHAR(8000) in a remoteview but the odbcjdbc tries to allocate 
-2 bytes
of memory (0xfffffffe). The bug appears in OdbcStatement.cpp at 
line 1157
...

   case SQL_C_CHAR:
//Orig
//				statement->setString (parameter, 
(char*) binding-
>pointer);
//				break;
//Suggested by CGA to handle situation where strings are NOT
null-terminated.
                switch( *binding->indicatorPointer )
                {
                    case SQL_NTS:
                        statement->setString (parameter, (char*)
                        binding->pointer ); break;

                    default:                       
                        statement->setString (parameter,
                        (char*)binding->pointer, *binding-
>indicatorPointer );
                        break;
                }

####
continuing in Value.cpp line 176f:
##
void Value::setString(int length, const char * string, bool copy)
 clear();
 type = String;
 copyFlag = copy;
 data.string.length = length;
 if (copy)
  {
  data.string.string = new char [length + 1];
  memcpy (data.string.string, string, length);
  data.string.string [length] = 0;
  }
 else
  data.string.string = (char*) string;
}
length is -2 and the (char *)string point to "newercombackmem" 

does anyone know, what to do ?

(in my VFP-remote-view this field is a "memo")
