Is is possible to create a program that will act as though your pressing the left and right keys?

(I ask because I have another game that I have to press the left and right keys as fast as possible. )
This is what I tried but it didn't work!

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim shoCount As Integer
Timer.Enabled = True
If Timer.Enabled = False Then
For shoCount = 1 To 600
ChrW(Keys.Left)
ChrW(Keys.Right)
Next
End If
End Sub


End Class
