How to set keyboard shortcut for ButtonClick Event?

I have a windows form which saves data on ButtonClick event but I also want to execute this event when user presses some key board shortcut such as : CTRL + S to save. I tried form's KeyDown event and KeyPress event but they just wont fire. I guess I am missing out something. 

 Private Sub frmExchangeSymbolMapping_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles MyBase.KeyPress
        If Asc(e.KeyChar) = Keys.Control AndAlso Asc(e.KeyChar) = Keys.E Then
            MessageBox.Show("Testing")
        End If
    End Sub

I will accept c# answers too (If it can be converted to vb using online tools :P )

If you set the Text for the button to &Save Alt-S will click the button assuming there isn't a menu intercepting the Ctrl-S.

Protected Overrides Function ProcessCmdKey(ByRef msg As Message, ByVal keyData As Keys) As Boolean
    Select Case msg.Msg
        Case &H100, &H104
            Select Case keyData
                Case Keys.Control Or Keys.E
                  MessageBox.Show("Control + E Pressed")
                  Exit Select
            End Select
      Exit Select
    End Select
    Return MyBase.ProcessCmdKey(msg, keyData)

My Solution is here in C#.

1. Set your Form KeyPreview Property to true.
2. Subscribe to the KeyDown Event of the Form as below:

this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.Form1_KeyDown);

3. handle the KeyDown event of Form as below:

    private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Control  && e.KeyCode == Keys.S)
            MessageBox.Show("Ctrl + S pressed!");
    }

Complete Code: 

this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.Form1_KeyDown);
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
     if (e.Control  &&  e.KeyCode == Keys.S)
       MessageBox.Show("Ctrl + S pressed!");
}

Set the KeyPreview property of the form to true. This will register all the key events with the form itself first and, if no shortcut is found, with the currently focused component.
