Question

In my application I need show a data in multiple forms that these forms exactly have same VCLs, events and procedures, because the amounts of these forms are depending on to my application, So I can’t create all of them in design-time.

Or How can I make a copy of a form multiple times in run-time?

Answer 1

Assuming your form is declared as TForm2, you can easily create say 10 instances of it like this:

var 
  myForms: TArray<TForm2>;
  I: Integer;
begin
  SetLength(myForms, 10);
  for I:=0 to 9 do begin
    myForms[I] := TForm2.Create(Application);  // Application will free the forms on exit
    myForms[I].Show;
  end;
end;

If you don’t need to access the form instances you can omit the array completely and write:

var 
  I: Integer;
begin
  for I:=0 to 9 do begin
    TForm2.Create(Application).Show;  // Application will free the forms on exit
  end;
end;
