Acquiring a Derived Class from the PropertyObject Class in Microsoft Visual C++/#import

In Microsoft Visual C++, you can use a class the #import directive generates to acquire a derived class from a dynamic property the PropertyObject class returns.

The following code uses a lookup string to obtain a reference to a Step object from the sequence context:

void Example (LPDISPATCH seqContextDisp){

TS::SequenceContextPtr sequenceContext = seqContextDisp;

TS::PropertyObjectPtr property;

TS::StepPtr step;

property = sequenceContext->AsPropertyObject();

step = property->GetPropertyObject("RunState.Sequence.Main[2]",0);

}
