vs2005下测试有点问题，主要是参数问题，改了一下：
void  asdkzoomExt()
{
      //get the extents of the drawing
      AcDbViewTableRecord view;
      AcGePoint3d max =
            acdbHostApplicationServices()->workingDatabase()->extmax(),
            min = acdbHostApplicationServices()->workingDatabase()->extmin();

      AcGePoint2d max_2d (max.x , max.y );
      AcGePoint2d min_2d (min.x , min.y );
      // now set the view centre point
      view.setCenterPoint (min_2d + (max_2d - min_2d) / 2.0);
      // now height and width of view
      view.setHeight(max_2d.y  - min_2d.y );
      view.setWidth (max_2d.x  - min_2d.x );
      // set the view
      acedSetCurrentView (&view, NULL);
      // updates the extents
      acdbHostApplicationServices()->workingDatabase()->updateExt(TRUE);
}

// This is command 'ZOOMWIN, by Fenton Webb [Apr/17/2002], DevTech, Autodesk
void  asdkzoomWin()
{
      AcGePoint3d max, min;
      // get the window coords
      int res = acedGetPoint (NULL, L"\nPick zoom window pnt : ",asDblArray(min));
      // if ok
      if (res == RTNORM)
      {
            res = acedGetCorner (asDblArray(min), L"\nPick other corner : ",asDblArray(max));
            // get the extents of the drawing
            AcDbViewTableRecord view;

            AcGePoint2d max_2d (max.x , max.y );
            AcGePoint2d min_2d (min.x , min.y );
            // now set the view centre point
            view.setCenterPoint (min_2d + (max_2d - min_2d) / 2.0);
            // now height and width of view
            view.setHeight(max_2d.y  - min_2d.y );
            view.setWidth (max_2d.x  - min_2d.x );
            // set the view
            acedSetCurrentView (&view, NULL);
            // updates the extents
            acdbHostApplicationServices()->workingDatabase()->updateExt(TRUE);
      }
}

这个好，恰好需要

版主，我没明年为什么为updateext，不要最后一个updateext有没有什么影响。我看手册里updateext会遍历所有对象再求ext，对象一多比如有几十万感觉影响速度啊
