CodeGear forums fail

Trying to post a question to the Delphi forums is no fun:

(not sure where to post this...)

How do I pass a Delphi string to a function expecting WCHAR* in a Visual C++ DLL?

I tried declaring the parameter as filename: PChar (and PWideChar) but I don't see the string being passed.

I get the following mess on the screen:
