Hi

Yes, I defined the function processInputPoint in filter.cpp

Thanks for replay,

Hi

I am creating newderived class “AsdkInputPointFilter" from Abstract class "AcEdInputPointFilter" in filter.h.

In Test 5.cpp file i trying to createreference from my derived class like this

AsdkInputPointFilter myFilter;

This gives compile error like this

e:\sankar\autocad objectarx 2007\testing project\copy of test 5\test 5\test 5.cpp(26) : error C2259: 'AsdkInputPointFilter' : cannot instantiate abstract class

due to following members:

'Acad::ErrorStatus AcEdInputPointFilter::processInputPoint(bool &,AcGePoint3d &,bool &,bool &,ACHAR *&,bool &,AcGiViewportDraw *,AcApDocument *,bool,int,const AcGePoint3d &,const AcGePoint3d &,const AcGePoint3d &,const AcGePoint3d &,const AcGePoint3d &,AcDb::OsnapMask,const AcArray<T> &,AcDb::OsnapMask,const AcArray<T> &,const AcArray<AcDbObjectId> &,const AcArray<AcDbObjectIdArray,R> &,const AcArray<int> &,const AcArray<AcDbObjectId> &,const AcArray<AcDbObjectIdArray,R> &,const AcArray<int> &,const AcArray<AcGeCurve3d *> &,const AcGePoint3d &,const ACHAR *)' : is abstract

with

[

T=AcDbCustomOsnapMode *,

R=AcArrayObjectCopyReallocator<AcDbObjectIdArray>
