Perform a function at a specific time in VB.NET

I am writing a small app to automatically connect my PC to the internet at a certain time and I am using rasdial.exe for it...

Priv开发者_C百科ate Sub SetIt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SetIt.Click
    Dim windir As String = Environment.GetEnvironmentVariable("WINDIR")
    Shell(windir & "\system32\rasdial.exe", AppWinStyle.NormalNoFocus)
End Sub

My question is how to make the shell function run at a specified time or after a certain interval??

Also how to wake up my PC from hibernation using vb and winresume.exe

Create a console application to do the work necessary, and then use a Windows Scheduled Task to do the scheduling work for you. My answer here shows how to accomplish the scheduling.
