Delphi Compiler Error

E2175 Field definition not allowed in OLE automation section

Reason for the Error & Solution

You have tried to place a field definition in an OLE automation section of a class declaration. Only properties and methods may be declared in an ‘automated’ section.

program Produce;

  type
    Base = class
    automated
      i : Integer;
    end;

begin
end.

The declaration of ‘i’ in this class will cause the compile error.

program Solve;

  type
    Base = class
      i : Integer;
    automated
    end;

begin
end.

Moving the declaration of ‘i’ out of the automated section will vanquish the error.
