不多说了,直接插代码:) 不用Api
public
Form1()
{
InitializeComponent();
Application.Idle
+=
new
EventHandler(Application_Idle);
}
private
void
Application_Idle(
object
sender, EventArgs e)
{
if
(Control.IsKeyLocked(Keys.NumLock))
labelNumLock.Text
=
"
ON
"
;
else
labelNumLock.Text
=
"
OFF
"
;
if
(Control.IsKeyLocked(Keys.CapsLock))
labelCapsLock.Text
=
"
ON
"
;
else
labelCapsLock.Text
=
"
OFF
"
;
if
(Control.IsKeyLocked(Keys.Scroll))
labelScrollLock.Text
=
"
ON
"
;
else
labelScrollLock.Text
=
"
OFF
"
;
if
(Control.IsKeyLocked(Keys.Insert))
labelInsert.Text
=
"
ON
"
;
else
labelInsert.Text
=
"
OFF
"
;
}
