Question

Is it possible to call a function whose name is stored in a string in Delphi?

Answer 1

With Delphi 2010 you can uses JSON and SuperObject to invoke method with parametters.

http://code.google.com/p/superobject/source/browse/#svn/trunk

If you need, there is also an xml parser to transform xml to json.

  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
    procedure TestMethod(const value: string);
  end;

var
  Form1: TForm1;

implementation
uses superobject;

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
  SOInvoke(Self, 'TestMethod', SO('{value: "hello"}'));
end;

procedure TForm1.TestMethod(const value: string);
begin
  Caption := value;
end;
