Addressing controls who's name is in a variable

Posted on 1998-09-12

How can I address the properties of a control whose name I have in a variable?

I have tried something like this:-

TControl(ControlName).Property := xxxx;

While compiles happily I get an address error on run. I realsie I am apparently typecasting the ControlName variable to TControl and this is probably the cause of the error but I can't see the way to solve the problem.

try the FindComponent Method.
Example for a form with a TLabel named label1 on it:

procedure TForm1.Button1Click(Sender: TObject);
a: string;
b: TComponent;
(b as Tlabel).caption:='NewText';

Thank you, I had implemented a find component using the component list of the form but I thought there must be a better way.
