Return Value
Specifies whether the application has set the input focus to
one of the controls in the dialog box. If OnInitDialog returns
nonzero, Windows sets the input focus to the first control
in the dialog box. The application can return 0/None only if
it has explicitly set the input focus to one of the controls in the
dialog box.
