[Mono-winforms-list] Windows Forms.

[Simon Ask Ulsnes]

I am not very skilled/experienced in Win32 programming, thus I have no idea
what a caret is used for... However, I could derive from the MSDN
documentation on the CreateCaret function that they are primarily used to
show/hide certain kinds of graphics?
Nothing that couldn't be achieved using the System.Drawing(.Drawing2D)
namespace.
(Please correct me if I'm wrong on this)

Yours sincerely,
Simon Ask Ulsnes, Denmark
