C++ Builder has some problems with assigning WideString properties, mostly 
C++ Builder 5 or previous, in C++ Builder 6 it is solved, but anyway it is 
safer to assign exactly WideString to property with type WideString. As I 
understand, sometimes C++ Builder uses incorrect constructor for WideString 
(or BSTR), for example, with char* (not wchar_t*) as parameter, but here I 
may be wrong.
