Question

i want to overload a procedure in a class.
for this i wrote:

type 

  TMyClass = class(TObject)
  private...
  ...
  public 
   constructor create;
   destructor destroy;
   procedure dosomething(filename: string); overload;
   procedure dosomething(s: string; t: string; u: string); overload;


implementation

  procedure dosomething(filename:string);
  begin
  end;

  procedure dosomething(s: string; t: string; u: string);
  begin
  end;

but delphi tells me an error regarding forward- or external declaration error…

why is that?

thanks in advance!

Answer 1

you must add the class name …

implementation   

procedure TMyClass.dosomething(filename:string);    
begin    
end;

procedure TMyClass.dosomething(s: string; t: string; u: string);    
begin    

end;
