<type1>'<typename>' must implement '<methodname>' for interface '<interfacename>'

  • Article

A class or structure claims to implement an interface but does not implement a procedure defined by the interface. Every member of the interface must be implemented.

Error ID: BC30149

To correct this error

  1. Declare a procedure with the same name and signature as defined in the interface. Be sure to include at least the End Function or End Sub statement.

  2. Add an Implements clause to the end of the Function or Sub statement. For example:

    Public Sub DoSomething() Implements IBaseInterface.DoSomething
