[SOLVED] Exception Class error on Checkbox

[Bazzao]

Under Delphi, creating a checkbox was easy.

I get an Exception Class error if I click in the checkbox ...

procedure TForm1.CheckBox1Click(Sender: TObject);
begin
  with CheckBox1 do
    begin
      Checked:=not Checked;
    end;
end;

What do you try to achieve? Checkbox changes its state automatically when clicked, your code will cause unchangeble checkbox. Even more, changing state triggers OnClick event, therefore your code causes endless loop.

Well how improved is that!

In old Dephi (acquired last century), you had to check it yourself -- hence the code.

I should think more in the future than in the past and forget what I learned all those years ago.

Many thanks Blaazen.
