Winforms Solution

In your Form class, set its KeyPreview property to true, example of it being set in the Form constructor, either set it here or via the Designer:

Public Sub New()
    ' This call is required by the designer.
    InitializeComponent()

    ' Add any initialization after the InitializeComponent() call.
    Me.KeyPreview = True
End Sub

Then all you need to do is handle the KeyDown event for the Form, like this:

Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles MyBase.KeyDown
    If (e.Control AndAlso e.KeyCode = Keys.S) Then
        Debug.Print("Call Save action here")
    End If
End Sub

WPF Solution (Not using MVVM pattern)

Add this to your .xaml file

<Window.Resources>
    <RoutedUICommand x:Key="SaveCommand" Text="Save" />
</Window.Resources>

<Window.CommandBindings>
    <CommandBinding Command="{StaticResource SaveCommand}" Executed="SaveAction" />
</Window.CommandBindings>

<Window.InputBindings>
    <KeyBinding Key="S" Modifiers="Ctrl" Command="{StaticResource SaveCommand}" />
</Window.InputBindings>

Alter your button definition to include Command="{StaticResource SaveCommand}", for example:

<Button x:Name="Button1" Content="Save" Command="{StaticResource SaveCommand}" />

In your Code Behind (.xaml.vb) put your function to call the save routine, such as:

Private Sub SaveAction(sender As Object, e As RoutedEventArgs)
    Debug.Print("Call Save action here")
End Sub
