Factory functions are nice for some things, but in general and in this case it's just more to write than simply defining a constructor. In other words, there was no particular reason to use a factory function. > That said, what I find unclear is the point of single-wchar_t fields in > that struct.

[windows.h] does not IMHO define any better, more readable name for `wchar_t`. However, [windows.h] does define e.g. MSGBOXPARAMS as a more readable alternative for MSGBOXPARAMSW, and it is not only more readable but also more easy to look up in the documentation (e.g., right-click and google). In modern Windows programming there is no practical reason to reserve that name for places where it might work to instead have it defined as MSGBOXPARAMSA, since (one just ensures that) it will never be defined as anything but MSGBOXPARAMSW. > Cheers and thank you anyway! > > Uli Cheers, - ALf
