Reference to a non-shared member requires an object reference occurs when calling public sub

Question

I have a Public Class "General" in which is a Public Sub "updateDynamics". When I attempt to reference it in the code-behind for a page like so:

updateDynamics(get_prospect.dynamicsID)

I get the following error:

reference to a non-shared member requires an object reference

Answer 1

You either have to make the method Shared or use an instance of the class General:

Dim gen = New General()
gen.updateDynamics(get_prospect.dynamicsID)

or

General.updateDynamics(get_prospect.dynamicsID)

Public Shared Sub updateDynamics(dynID As Int32)
    ' ... '
End Sub

Shared(VB.NET)

Answer 2

Go to the Declaration of the desired object and mark it Shared.
