Question

I am relatively new to development within COM, and I was wondering what the community standard was for access of COM object properties. I have seen both of the following conventions in code:

comObjectPtr->PutValue(value); 

and

comObjectPtr->Value = value; 

and both seem to work, but I was wondering if there was an inherent advantage or disadvantage to either approach and why.

Answer 1

If I remember correctly, using the property assignment will throw an exception vs. a HRESULT returned in the setter if there is a problem.

Same thing is true of the getter method calls vs. property.

A ‘benefit’ of using the property is that you can use the prop-get values directly instead of having to declare a variable and getting it before using.
