ACAD2013 - acedssget issue

[Anonymous]

Hi,

I'm experiencing sometimes an issue with acedssget()

I call this function with these parameters

acedSSGet(_T("C"), ads_point1, ads_point2 , NULL, ssname);

I have custom entities ihneriting from acdbline with extended dictionaries.

I draw a network of acdbline and I construct with a recursive funcion the tree representing the network.

Sometimes it works, but sometimes it doesn't and on a selection it don't return all the crossing elements..

Why?

I think it's due to some object opened and not properly closed in my algorithm.. could it be?

Is there a function to close all open object on the database? or to flush some data used by acedSSGet?

Thank you for your help.

are you checking the errors on the functions you call? if you are you will find what is not closed etc. What does acedSSGet return?

Hi,

SSGET return always 5100 RTNORM,

but it doesn't return all the objects I expect.

I tried to move(with a MOVE command) some unselected objects and reposition in the same position as they were, and after this operation, ssget works well.

What could be the cause?

Thank you for your time.

objects inside ads_point1-ads_point2 box MUST be on the screen (visible).
so, try to zoom window (ads_point1-ads_point2) before acedSSGet

Hi,

you are right!!

How can I zoom out with objectarx at all to show all the objects on my drawing?

Thank you a lot!

You can use the AutoCAD Command _Zoom and do a _Zoom _Extents:

acedCommand( RTSTR, _T("_ZOOM"), RTSTR, _T("_E"), RTNONE );

Or you can use a function like this to define your Zoom Window:

void SetZoomWindow( AcGePoint3d ul, AcGePoint3d or, double fakt )
{
	AcGePoint3d		mid, lu, ro;
	AcGeVector3d	dv;

	mid = ul+(or-ul)/2.0;

	dv = (ul-mid)/fakt;
	lu = mid+dv;

	dv = (or-mid)/fakt;
	ro = mid+dv;

	AcDbViewTableRecord view;
	AcGePoint2d max_2d( ro[X], ro[Y] );
	AcGePoint2d min_2d( lu[X], lu[Y] ); 


	view.setCenterPoint( min_2d + (max_2d - min_2d) / 2.0 );
	view.setHeight( max_2d[Y] - min_2d[Y] );
	view.setWidth( max_2d[X] - min_2d[X] );     
	acedSetCurrentView( &view, NULL );
}

If you want to iterate through model space entities to get/modify your lines you can do something like this:

#include "dbobjptr.h"
#include "dbobjptr2.h"
//...

//get the modelspace pointer of the current database
AcDbBlockTableRecordPointer ms(ACDB_MODEL_SPACE,acdbHostApplicationServices()->workingDatabase(),AcDb::kForWrite); 
if(ms.openStatus()==Acad::eOk)
{
   AcDbBlockTableRecordIterator *pIter;
   if (ms->newIterator(pIter )==Acad::eOk)
   {
      AcDbObjectId oid;
      AcDbSmartObjectPointer<MyLineType> line(oid,AcDb::kForWrite);//opened for modify
      if (line.openStatus()==Acad::eOk) //will fail if object pointed by oid is not a MyLineType
      {
         line->foo();//process here
      }
      delete pIter;//don't forget to delete the pointer, ms would be "corrupted" for further use
   }
}

 Cheers
