Hi, make something like that:

VB

Dim readValue As String
readValue = CStr(My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\ARSS", "EPV", Nothing))

If Not String.IsNullOrEmpty(readValue) Then
    '....
End If

And one advice, set the project option 'strict' to 'on' - then you should get an error at compile time.

You give something to readValue, so it wouldn't display a error, even with 'strict on'
just use
readValue = CStr(My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\ARSS", "EPV", ""))
instead ^^
so even 'If readValue <> "" Then' would work
