Go Up to Error and Warning Messages (Object Pascal) Index

You have incorrectly tried to put a constructor or destructor into the 'automated' section of a class declaration.


program Produce;

  type
    Base = class
    automated
      constructor HardHatBob;
      destructor  DemolitionBob;
    end;

  constructor Base.HardHatBob;
  begin
  end;

  destructor Base.DemolitionBob;
  begin
  end;

begin
end.

It is not possible to declare a class constructor or destruction in an OLE automation section. The constructor and destructor declarations in the above code will both elicit this error.


program Solve;

  type
    Base = class
      constructor HardHatBob;
      destructor  DemolitionBob;
    end;

  constructor Base.HardHatBob;
  begin
  end;

  destructor Base.DemolitionBob;
  begin
  end;

begin
end.

The only solution to this error is to move your declarations out of the automated section, as has been done in this example.
