[The Shadow]

Код:

if not FileExists(ExtractFilePath(Application.ExeName) + 'Params.ini') then
Form1.ShowModal;
with TIniFile.Create(ExtractFilePath(Application.ExeName) + 'Params.ini') do
begin
WinExec(PChar(ReadString('Param1', 'Params', ''), SW_SHOWNORMAL);
WinExec(PChar(ReadString('Param2', 'Params', ''), SW_SHOWNORMAL);
Free;
end;

А в событии OnClose второй формы

Код:

with TIniFile.Create(ExtractFilePath(Application.ExeName) + 'Params.ini') do
begin
WriteString('Param1', 'Params', Edit1.Text);
WriteString('Param2', 'Params', Edit2.Text);
Free;
end;

Вроде так.
