The following code example uses the AssociatedControl and HardwareKey properties to display a form whenever the first and fourth buttons on Pocket PC are pressed. This code example is part of a larger example provided for the HardwareButton class.
Private Sub ConfigHWButton() 'Set KeyPreview to true so that the form 'will receive key events before they 'are passed to the control that has focus. Me.KeyPreview = True hwb1 = New HardwareButton() hwb4 = New HardwareButton() 'Set the AssociatedControl property 'to the current form and configure the 'first and fourth buttons to activate the form. Try hwb1.AssociatedControl = Me hwb4.AssociatedControl = Me hwb1.HardwareKey = HardwareKeys.ApplicationKey1 hwb4.HardwareKey = HardwareKeys.ApplicationKey4 Catch exc As Exception MsgBox(exc.Message + " Check if the hardware button is physically available on this device.") End Try End Sub Private Overloads Sub OnKeyUp(sender As Object, e As KeyEventArgs) Handles MyBase.KeyUp ' When a hardware button is pressed and released, ' this form receives the KeyUp event. The OnKeyUp ' method is used to determine which hardware ' button was pressed, because the event data ' specifies a member of the HardwareKeys enumeration. Select Case CType(e.KeyCode, HardwareKeys) Case HardwareKeys.ApplicationKey1 statusBar1.Text = "Button 1 pressed." Case HardwareKeys.ApplicationKey4 statusBar1.Text = "Button 4 pressed." Case Else End Select End Sub
