Hi ghjlk,

something like this?

uses
   ..., TypInfo,.....

function SetPropertyValue(const FormName, ComponentName, PropName, Value: String): Boolean;
var
  I: Integer;
  C: TComponent;
begin
  Result := False;
  for I := 0 to Screen.FormCount - 1 do
    if CompareText(Screen.Forms[I].Name, FormName) = 0 then
    begin
      C := Screen.Forms[I].FindComponent(ComponentName);
      if C <> nil then
      begin
        if CompareText(PropName, 'COLOR') = 0 then
          SetPropValue(C, PropName, StringToColor(Value))
        else
          SetPropValue(C, PropName, Value);
        Result := True;
      end;
    end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  SetPropertyValue('Form1', 'Label1', 'Color', 'clRed');
  SetPropertyValue('Form1', 'Label1', 'Left', '10');
  SetPropertyValue('Form1', 'Label1', 'Alignment', 'taRightJustify');
end;
