I need a dialog for the user to select files to delete. The TOpenDialog works just 
fine except that the button says Open, and I need it to say Delete.

Answer:

You will need to include Commdlg in your uses clause. In the TOpenDialog.OnShow 
event:
1   
2   procedure TForm1.OpenDialog1Show(Sender: TObject);
3   begin
4     SendMessage(GetParent(OpenDialog1.Handle), CDM_SETCONTROLTEXT, 1,
5       Integer(PChar('Delete')));
6   end;
