Welcome to TSDN. I suggest using KeyCode values in the KeyUp (or KeyDown) event, i.e. keypress won't work. HTH.

The KeyPress event is not missing. If you want to get the ASCII code of the key pressed in the KeyPress event, use the KeyPressEventArgs' KeyChar property to get the Char representing the key pressed, and then convert it to an ASCII keycode using AscW. Also, if you want to determine whether a Char is numeric or alphabetic, you can use the IsNumber and IsLetter shared methods of Char. For example:
Code:

Private Sub frmGame_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) _
Handles MyBase.KeyPress
Dim keyascii As Integer = AscW(e.KeyChar)
Dim bNumber As Boolean = Char.IsNumber(e.KeyChar)
Dim bLetter As Boolean = Char.IsLetter(e.KeyChar)
End Sub

but how to organize another scenario?

1. you have a loop in
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint

2. pressing a key you have to jump in
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress

3. and go back to
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint

Call the Form1_KeyPress in Form1_Paint.
Note: better generate a method and call anywhere. Event should call only on event activated.
