buttonOK->Location = Point(136,248);
buttonOK->Size = System::Drawing::Size( 75, 25 );
// Set the Text property and make the
// button the form's default button.
buttonOK->Text = "&OK";
this->AcceptButton = buttonOK;
// Set the button size and location using the Top,
// Left, Width, and Height properties.
Button^ buttonCancel = gcnew Button;
buttonCancel->Top = buttonOK->Top;
buttonCancel->Left = buttonOK->Right + 5;
buttonCancel->Width = buttonOK->Width;
