Edit in a MessageDlg

just use a form
-set the borderstyle to bsDialog
-place your controls and buttons
-assign a modalResult to the buttons

and use it in your code like

with TMyNewDialog.Create(self) do
begin
  result := showmodal;
  if result = mrOK then
  //.. read out your edits here
     something := DialogEdit1.text;
  //free it
  release;
end;

just as suggestion

Even easier. Use InputQuery (ij the Dialogs unit). There are a few versions for strings, integers, reals etc.

Correction: (IN the Dialogs unit).

ouch, this nice  looking inputquery-box (sarkasm),
but well, maybe its enough
