form and control keyevent一、form的keyevent
keycode:
private void form1_keydown(object sender, keyeventargs e)
{
if ((e.modifiers == keys.control) && (e.keycode == keys.z))
{
this.cancelhandler();
}
else if ((e.modifiers == keys.control) && (e.keycode == keys.s))
{
this.savehandler();
}
else
e.handled = true;
}
二、control’s keyevent
检测输入control的字符的正确性。
private void textbox1_keypress(object sender, keypresseventargs e)
{
if (e.keychar == 'b')
mpwflag[0] = e.keychar;
if (e.keychar == 'a')
mpwflag[1] = e.keychar;
if (e.keychar == 't')
mpwflag[2] = e.keychar;
if (e.keychar == '1')
mpwflag[0] = e.keychar;
if (e.keychar == '2')
mpwflag[1] = e.keychar;
if (e.keychar == '3')
mpwflag[2] = e.keychar;
if (mpwflag[0] == 'b' && mpwflag[1] == 'a' && mpwflag[2] == 't')
{
mpwflag[0] = '0';
mpwflag[1] = '0';
mpwflag[2] = '0';
batcreatetopic bct = new batcreatetopic(this);
this.button3.visible = true;
bct.showdialog(this);
}
}
