hardware buttons

[Guest]

Hi NG,

I use this code, but if I put on one Hardwarebutton I get 2 Messages. What
is wrong?

Greetings

public partial class DialogLearn : Form
{
private HardwareButton hwb1, hwb4;

public DialogLearn()
{
KeyPreview = true;
KeyUp += new KeyEventHandler(DialogLearnOnKeyUp);
HBConfig();
}

void DialogLearnOnKeyUp(object sender, KeyEventArgs e)
{
MessageBox.Show(e.KeyCode.ToString());
}

private void HBConfig()
{
try
{
hwb1 = new HardwareButton();
hwb4 = new HardwareButton();
hwb1.AssociatedControl = this;
hwb4.AssociatedControl = this;
hwb1.HardwareKey = HardwareKeys.ApplicationKey1;
hwb4.HardwareKey = HardwareKeys.ApplicationKey4;
}
catch (Exception exc)
{
MessageBox.Show(exc.Message + " Check if the hardware button is
physically available on this device.");
}
}

Hi,

You must add this on KeyUp:

switch ((HardwareKeys)e.KeyCode)
{
case HardwareKeys.ApplicationKey1:
MessageBox.Show(e.KeyCode.ToString());
break;

case HardwareKeys.ApplicationKey4:
MessageBox.Show(e.KeyCode.ToString());
break;

default:
break;
}
