OK. So I'm making a simple game that is a car that moves around the screen according to the arrow keys. i have made code to rotate the car inside the picturebox, but i don't know how to make the car move in the direction that it is facing after the turn. please help. my code so far.....

```
Imports System.Math
Public Class Form2
Private Sub tmrRotate_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tmrRotate.Tick
Dim bm_in As New Bitmap(picCar.Image)
Dim wid As Single = bm_in.Width
Dim hgt As Single = bm_in.Height
Dim corners As Point() = { _
New Point(0, 0), _
New Point(wid, 0), _
New Point(0, hgt), _
New Point(wid, hgt)}
Dim cx As Single = wid / 2
Dim cy As Single = hgt / 2
Dim i As Long
For i = 0 To 3
corners(i).X -= cx
corners(i).Y -= cy
Next i
Dim theta As Single = Single.Parse(lblAngle.Text) * PI / 180.0
Dim sin_theta As Single = Sin(theta)
Dim cos_theta As Single = Cos(theta)
Dim X As Single
Dim Y As Single
For i = 0 To 3
X = corners(i).X
Y = corners(i).Y
corners(i).X = X * cos_theta + Y * sin_theta
corners(i).Y = -X * sin_theta + Y * cos_theta
Next i
Dim xmin As Single = corners(0).X
Dim ymin As Single = corners(0).Y
For i = 1 To 3
If xmin > corners(i).X Then xmin = corners(i).X
If ymin > corners(i).Y Then xmin = corners(i).Y
Next i
For i = 0 To 3
corners(i).X -= xmin
corners(i).Y -= ymin
Next i
Dim bm_out As New Bitmap(CInt(-2 * xmin), CInt(-2 * ymin))
Dim gr_out As Graphics = Graphics.FromImage(bm_out)
ReDim Preserve corners(2)
gr_out.DrawImage(bm_in, corners)
picCar.Image = bm_out
End Sub
Private Sub Form2_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.Left
lblAngle.Text -= 1
If lblAngle.Text < 0 Then
lblAngle.Text = 359
End If
End Select
Select Case e.KeyCode
Case Keys.Right
lblAngle.Text += 1
If lblAngle.Text > 359 Then
lblAngle.Text = 0
End If
End Select
Select Case e.KeyCode
Case Keys.Escape
End
End Select
Select Case e.KeyCode
Case Keys.Up
End Select
End Sub
End Class
```

Thanks in advance.
