It should be:

Public newRuntimeClass As New NewRuntimeMethods

When i place the New keyword in front of the class it will ask me for
all these parameters.
 
Then it appears your constructor for the NewRuntimeMethods requires
parameters to be passed to it. You must then do something like

Public newRuntimeClass as New NewRuntimeMethods(a, b, c)

Also, I believe you meant to say you get the "object not set to instance"
error at runtime. It shouldn't happen at compile time.
 
It should be:

Public newRuntimeClass As New NewRuntimeMethods

I also checked it on vb.net 2005 "express" but there's nothing called
"newRuntimeMethods".

Only "RuntimeMethodHandle" exists with most similarity. Is it a
special class or not express version?

It seems to have to do something with scanning barcodes as it has a
'ScannedBarCode' property.
