The section "Calling Windows API" says:
 'Only the "W" versions of Windows API functions should be called. It
is like in Delphi except that you must assign strings to/from API
calls to UnicodeString variables or typecast with UnicodeString().'
Then it also explains the difference between WideString and UnicodeString.
I should add a mention about PWideChar parameters.
Anyway the idea is to keep the information useful and dense. Earlier
it was bloated and intimidating.

No, if the parameter is WideString, not a pointer PWideChar, you can
just call it like you did. Suppress the warning as Mattias told if it
bothers you. You can also make a helper function so the conversion
happens in one place.
Yes, for OLE you need WideString.
