Just for clarity, that is not a string. It is a wide string inside a
value box. If you're using that with omniORB, you must be using the
omniORB 4.1 pre-release.

This one is a string, not a wide string. If you want to send it as a
wstring, you have to convert it. The ORB won't do it for you.

Aside from that, you just need to create a WStringValue using a suitable
constructor, giving it either a wchar_t* or a const wchar_t*, depending
on whether you want it to take ownership of the wstring or not, then
pass it to the operation.

Cheers,

Duncan.
