compile errors when deriving a class from oddbdxffiler
compile errors when deriving a class from oddbdxffiler
hi,
i am trying to derive a class from oddbdxffiler in order to write out dxf fields. i changed the code in the odamfcapp listfiller and am trying to include it in the example odreadex but i am getting many compile errors. finally i found some code on the forum, which is almost like mine, and tried it. i get the same errors. here is the code:
#include "dbfiler.h"
#include "rxobjectimpl.h"
#include "odstring.h"
class custfiller: public odrxobjectimpl<oddbdxffiler>
{
public:
int m_n70;
custfiller(){m_n70 = 0;}
filertype filertype() const {return oddbfiler::kcopyfiler;}
void wrstring(int groupcode, const odchar *string){}
/*..............*/
void wrint16(int groupcode, odint16 val){
if (70 == groupcode) m_n70 = val;
}
/*...........*/
};
i get over 100 compile errors when i try to compile this. some of them are listed below. i've attached a file with all of them if that helps.
i am using opendwg 1.11 with vc 7.0 (vis studio 2003).
i must be leaving something out but i have tried everything i know and can't get any further. any help will be greatly appreciated.

i think you just need to #include "odacommon.h" and perhaps some other headers.
