Hi,

one hour trying to get a string out of LPOLESTR*.
What is the correct command to get rgszNames as string?

HRESULT GetIDsOfNames(REFIID riid, LPOLESTR* rgszNames, UINT cNames, 
LCID lcid, DISPID* rgDispId){}

With following command I only get the first character
writeln(to!string(**rgszNames));

Kind regards
André

I would assume to!string(*rgszNames). Assuming LPOLESTR is char* or some 
such, then LPOLESTR** is char**, so **LPOLESTR would be the first 
character in the string, and *LPOLESTR would be the char* string.

to!string(*rgszNames) outputs a number instead of a name.
I think I am a step further, rgszNames is an array but also with 
to!string(*rgszNames[0]) only the first character of my method is given 
back.

Kind regards

std.conv.to knows about char* c-style strings, but not wchar* 
c-style strings like LPOLESTR. The number you are getting is the 
pointer to the first wchar.

I'm not sure what is the best way to do this as it's not 
something I've come across before, hopefully someone else will 
know.

I'm pretty sure you can get a wstring like this:

import core.stdc.wchar_ : wcslen;
auto rgszNamesWStr = to!wstring(rgszNames[0][0 .. 
wcslen(rgszNames[0])]);

Or if you're sure you don't have any wide characters:

auto rgszNamesStr = to!string(rgszNames[0][0 .. 
wcslen(rgszNames[0])]);

to!string on a well-formed UTF-16 string is always safe. It will 
transcode to UTF-8.

Awesome. Sorry for the misinformation, I don't really know a lot 
about phobos w.r.t. unicode. There was some talk of an article on 
it by someone, but I don't remember seeing it happen.
