Question

I have a procedure with Sender: TObject paramater

procedure TForm1.FormCreate(Sender: TObject);

How can I call this procedure again?

This version does not work:

TForm1.FormCreate(Sender: TObject);

Thanks in advance.

I assume that you wish to call the procedure FormCreate of an instance of a TForm1.

You can do FormCreate(Self) or FormCreate(nil) (or you can pass any TObject instance as the parameter) if you are inside the TForm1 class. Otherwise, you have to write Form1.FormCreate(Self) or Form1.FormCreate(nil) or similarly, where Form1 is the appropriate instance of the TForm1.

At any rate, it is not particularly ‘elegant’ to call the FormCreate procedure at later times. Indeed, the name clearly suggests that the procedure is called when the form is created.

If a particular piece of logic of your FormCreate method is needed at other stages and you simply do not want to duplicate code, you should probably implement that piece in the form of a separate method (procedure or function) and call it in FormCreate as well as in other parts of your program, as necessary.

But then, you might be better off moving that part of your business logic from FormCreate at all. What we typically do in FormCreate is create/initialise objects that are later uninitialised/destroyed in FormDestroy (if needed). So, think carefully what you are doing in FormCreate, maybe there’s a better, logically more appropriate place for some or all of the actions you’ve implemented in this method.
