Start Program At Startup With Registry

[kshadow22]

I am currently trying to get my program to start up at Windows Startup. However, every code I create or find, I get errors thrown at me. I can't seem to get this to work no matter how many times I change my codes. Could someone please help me?

Here is my code:

Imports Microsoft.Win32
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim regkey As Microsoft.Win32.RegistryKey
        Dim Keyname As String = "SOFTWARE\Microsoft\Windows*\CurrentVersion\Run" 'Registrypath
        Dim ValueName As String = Application.ProductName 'Program name
        Dim Value As String = Application.ExecutablePath
        'Create Startup
        regkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(Keyname, True)
        regkey.SetValue(ValueName, Value, RegistryValueKind.String)
    End Sub
End Class

Here is the error that is thrown at me every time I try to run the function:
An unhandled exception of type 'System.NullReferenceException' occurred in WindowsApplication3.exe

Additional information: Object reference not set to an instance of an object.

How can I fix this? I know this should have been easy and fairly simple to do. I've been trying to work just this one function for hours. Any help would be greatly appreciated!
