Events of shared WithEvents variables cannot be handled by non-shared methods
A variable declared with the Shared modifier is a shared variable. A shared variable identifies exactly one storage location. A variable declared with the WithEvents modifier asserts that the type to which the variable belongs handles the set of events the variable raises. When a value is assigned to the variable, the property created by the WithEvents declaration unhooks any existing event handler and hooks up the new event handler via the Add method.
