| 3 | + | Die Prozedur verhindert das Beenden des eigenen Programms durch den Anwender. | |

| 5 | + | Dafür muss das Ereignis OnCloseQuery der [[TForm/de|Form]] angepasst werden. | |

| 7 | + | Beispiel: | |
| 8 | + | ||
| 9 | + | ``` pascal | |
| 10 | + | uses | |
| 11 | + | Forms, ...; | |
| 12 | + | ||
| 13 | + | ... | |
| 14 | + | ||
| 15 | + | procedure TForm1.FormCloseQuery(Sender: TObject; var CanClose: Boolean); | |
| 16 | + | begin | |
| 17 | + | CanClose:=false; | |
| 18 | + | end; | |
| 19 | + | ||
| 20 | + | ... | |
