How can I change my form's properties at run-time?

In the C++Builder IDE, I can easily change different settings of my form (for example, the Caption) using the Object Inspector. How can I access these settings at run-time?

Start a new project using File | New Application.

Add a Button and double-click its OnClick event:

void __fastcall TForm1::Button1Click(TObject *Sender)

{

// Change caption

Caption = "My Caption";

// Change color

Color = clBlue;

}

As you can see, changing properties at run-time is also very easy. Simply specify the property and the new value.
