How to suppress items in a rectangular pattern?

[oransen]

If I have a RectangularPattern how do I suppress individual features in the pattern.

For example I have a single row of holes, and I want to suppress the odd numbered holes.

I've tried this...

        CComPtr<FeaturePatternElements> pFeaturePatternElements ;
        pRectPatFeat->get_PatternElements (&pFeaturePatternElements) ;

        const int ikNumElements = pFeaturePatternElements->GetCount() ;
        wprintf (L"   this has %d FeaturePatternElements\n",ikNumElements) ;

        for (int iElem = 1 ; iElem < ikNumElements ; iElem++) {
            CComPtr<FeaturePatternElement> pFeaturePatternElement ;
            pFeaturePatternElements->get_Item (iElem,&pFeaturePatternElement) ;

            // CRASH here....
            pFeaturePatternElement->Suppressed = (((iElem/2)*2) == iElem) ;
        }

... but it crashes at the assignment of Suppressed

Hope this post could give you some idea:

Thanks for the link, but it seems to have been a C++/COM problem.

If I use put_Suppressed() it works and does not crash.

If I used Suppressed =  (as in my original post) it does.

Hey ho hum.

Hi,

I've just written a blog post about this: http://adndevblog.typepad.com/manufacturing/2013/08/crash-when-not-using-raw-com-interface-to-set-pr...
