[求助] CATIA二次开发，零件环境下关于面选择以及颜色改变的问题

CATDocument * pDocument = NULL ;
CATIPrtContainer_var spPartContainer = NULL_var;
CATFrmEditor * pEditor =CATFrmEditor::GetCurrentEditor();

if (pEditor!=NULL)
{
CATPathElement spPath = pEditor->GetUIActiveObject();
CATBaseUnknown* spRef = spPath.CurrentElement( );
if (spRef)
{
CATILinkableObject *piLinkableObject = NULL;
HRESULT rc = spRef->QueryInterface(IID_CATILinkableObject,(void**)& piLinkableObject);
if ( SUCCEEDED(rc) )
{
pDocument = piLinkableObject->GetDocument();
piLinkableObject->Release();
piLinkableObject = NULL ;
if ( NULL != pDocument )
{
CATInit_var spInit = pDocument;
spPartContainer = (CATIPrtContainer*) spInit -> GetRootContainer("CATIPrtContainer"

;
}
}
}
}
CATPathElement * pPathSelected = _pSelectionPlane1-> GetValue ();
CATFrmEditor * pEdt = GetEditor();
CATHSO * pHSO = pEdt -> GetHSO();
if ( pHSO )
{
pHSO -> Empty();//清除以前已高亮的
pHSO -> AddElements (pPathSelected);
}

CATUnicodeString luoshuangpingmian="未选择";
_dlg->_SelectorList006->GetLine(luoshuangpingmian,0);
if (_dlg->_SelectorList006->IsSelect(0))
{
CATUnicodeString Plane;
Plane.BuildFromNum(PlaneNum);
_dlg->_SelectorList006->SetLine(("平面."+Plane),0,CATDlgDataModify);
PlaneNum++;
_dlg->_SelectorList007->SetLine(("未选择"

,0,CATDlgDataModify);
_dlg->_Editor012->ClearLine();
CATPlane_var AssPlane=pPathSelected->FindElement(IID_CATPlane);
CATCell_var piFace;
HRESULT rc;
HRESULT rc1;
rc=AssPlane -> QueryInterface(IID_CATCell,(void**) &piFace);

CATIPrtPart_var spPrtPart=spPartContainer->GetPart();
CATIPartRequest_var spPartRequest = spPrtPart ;

rc = spPrtPart->QueryInterface(IID_CATIPartRequest,(void**)&spPartRequest) ;

CATLISTV(CATBaseUnknown_var) spMainPartBody;
spPartRequest->GetSolidBodies("",spMainPartBody);
for (int j=1;j<=spMainPartBody.Size();j++)
{
CATIBodyRequest_var spMainPartBodyBodyRequest=spMainPartBody[j];
CATLISTV(CATBaseUnknown_var) ListResult;
spMainPartBodyBodyRequest->GetResults("",ListResult);
CATIGeometricalElement_var spFeatureResultGeomElem=ListResult[1];
CATBody_var spPartTopoBody = spFeatureResultGeomElem->GetBodyResult();

CATIGeometricalElement *pGeomEltOnCurFeat1 = NULL;
rc=spPartRequest->QueryInterface(IID_CATIGeometricalElement,(void**)&pGeomEltOnCurFeat1);
if (rc)
{
CATIGeometricalElement_var pGeomEltOnCurFeat=pGeomEltOnCurFeat1;

CATIBRepAccess_var spBRepAccess =CATBRepDecode(piFace, pGeomEltOnCurFeat) ;
CATIVisProperties_var pIPropertiesOnSurface2=spBRepAccess;
CATVisPropertiesValues MyPropertyOnSurface2 ;
CATVisPropertyType PropTypeOnSurface2 = CATVPAllPropertyType;
CATVisGeomType GeomTypeOnSurface2 =CATVPMesh ;

rc1 = pIPropertiesOnSurface2->GetPropertiesAtt(MyPropertyOnSurface2,PropTypeOnSurface2, GeomTypeOnSurface2);

if (rc1)
{
unsigned int r1,g1,b1;
MyPropertyOnSurface2.GetColor(r1,g1,b1);
cout<<r1<<" "<<g1<<" "<<b1<<endl;

MyPropertyOnSurface2.SetColor(0,255,0);
rc =pIPropertiesOnSurface2->SetPropertiesAtt(MyPropertyOnSurface2,CATVPColor,CATVPMesh);
}

}

}

}

_SelectorList006是我的一个SelectorList的控件名称，我希望点选SelectorList后再点选零件的一个面，那个面能够改变颜色。但是运行调试的时候，总是显示斜体的那一行（rc1 = pIPropertiesOnSurface2->GetPropertiesAtt(MyPropertyOnSurface2,PropTypeOnSurface2, GeomTypeOnSurface2);），handler is null。
请问我这种方法对不对，以及，如果方法是对的，那么为什么这里的接口会成空的？
