c# - KeyUp And KeyDown arent registering -
i don't registered when i'm key down , key heres code:
private void form1_keydown(object sender, keyeventargs e) { switch(e.keycode) { case keys.a: messagebox.show("hi"); walking = true; break; } } private void form1_keyup(object sender, keyeventargs e) { walking = false; } i don't :(
heres rest of code if helps
public partial class form1 : form {

make sure form's keypreview property set true events coded can work.
private void form1_load (object sender, eventargs e) { this.keydown += form1_keydown; this.keyup += form1_keyup; this.keypreview = true;
