If you want use COM in LabVIEW, you have 2 options:
1) COM with GUI - create on Front Panel ActiveX/ Container, click right button and select Insert ActiveX Object.
2) COM without GUI - create on Front Panel ActiveX/Automation Refnum, click right button and Select ActiveX. On diagram you have use Automation Open for opening of object and Automation Close for closing.

If your question is about how create COM object with LabVIEW - the answer is "You can't"

Are you refering to Serial Interface?

If yes, the easiest way is to use Serial Compatibility vi(s) at

Functions Palette> Instrument I/O> I/O Compatibility> Serial Compatibility

Alternatively, you may wanna use VISA for Serial at

Functions Palette> Instrument I/O> Serial


Try to locate some example codes on Serial Interface as well.

I think I am having brain-dead now... just write anything that's in my mind. This might be gone out of topic 😛

Hello,

I think my question was a little bit unclear. I want to use C++/Microsoft COM (Common Object Model) Interfaces.

Use the ActiveX open node on the diagram. Create a input constant for
the type specifier and browse to the typelib for the interface. LV
supports a subset of the datatypes that are needed for Automation
interfaces, but these are the most common anyway. From the open you can
connect Invoke and Property nodes to access the interface elements.
