SendKeys - Hold Down a Key

100ms will give you 10 per second which seems reasonable. Fastest available in Windows is around 30 per second, slowest around 3. Anything much faster than 10 will put you in less reliable timer country however.

Alright well here is my code so far. The problem is that it freezes the program and sometimes even my computer. But it does everything else correctly. I was thinking about using a BackgroundWorker but how would I stop it once it started?

Imports System
Imports System.IO
Imports Microsoft.VisualBasic
Public Class Form1

    Private Sub CheckBox1_CheckedChanged(sender As Object, e As EventArgs) Handles CheckBox1.CheckedChanged

        Dim X As Integer
        X = 1

        If CheckBox1.Checked Then
            Do While X = 1
                SendKeys.Send("W")
                Threading.Thread.Sleep(25)
            Loop
        End If

    End Sub
End Class
