E2250 There is no overloaded version of 'MessageDlg' that can be called with these arguments

[Frederick]

I have UniGUIDialogs and no VCL.Dialogs in the Uses line. However, when I make the following call:-

messagedlg('Test Message', mtConfirmation, mbYesNo, SomeFunc);

Delphi 10S throws up an error of "E2250 There is no overloaded version of 'MessageDlg' that can be called with these arguments".

What am I missing here?

I found the problem in that the callback procedure was missing a parameter of "Sender : TComponent" as like

procedure TUniForm.SomeFunc(Sender : TComponent; Res : Integer);
begin
      // Some code
end;
