Re: [Dev-C++] ANSI problem

[Per W. <pw...@ia...>]

A HPEN isn't just a numeric handle. It is a pointer to an object.

SelectObject() doesn't know what type of selection is made
(pen,brush,...), so the declaration of it can't just specify HPEN as
return value.

You have to make a type cast on the returned value.
