Syntax of get_Item call in C++

[oransen]

I've seen pPointer->get_Item used in many examples but the way of passing the first index argument changes. Some examples...

   get_Item(COleVariant(CGID)...

   get_Item(CComVariant(j),...

   get_Item(_variant_t(3L, VT_I4),...

In these three examples they all get cast to different types. Are they all equivalent when get_Item simply requires an index?

This may be more a COM than Inventor API question, but any help would be appreciated...

Hi,

Are you experiencing any issues with any of them?

If you are just simply wondering about the differences between them then yes, asking a COM programming forum might be a better option 🙂

Inventor API is just like any other COM API, inc. e.g. the Office product API's

Cheers,

No I was not experiencing problems, except my own slow learning speed! I'll try to get to grips with COM more...
