9 | // Successful tested with: // |
||
10 | // Windows 95b, 95b + IE4, 98-SE, XP-SP2, 2000-SP4, 2003-SRV-EE-SP1, VISTA // |

13 | // Needs Delphi 4 or higher. If you are using Delphi 4 or 5, you can not use the // |
||
14 | // RecyclerGetDateTime() functions, because the unit "DateUtils" is missing. // |
||
15 | // Warning! This is a platform unit. // |
||
16 | // // |
||
17 | // To do! Can you help? // |
||
18 | // - WideString-Support (input/output) // |
||
19 | // - GetLoginNameW: Really 255 maximum? // |
||
20 | // - Always do EOF before reading anything? // |
||
21 | // - Is it possible to identify a Vista-file that is not named $Ixxxxxx.ext? // |
||
22 | // - RecyclerGetInfofiles() check additionally for removable device? // |
||
23 | // RecyclerIsValid() is false. // |
||
24 | // - Function to get current state of recycle-bin (full, empty) // |
||
25 | // - Make functions to get the correct icons of full, empty, current // |
||
26 | // // |
||
27 | // Unknown! Do you know the answer? // |
||
28 | // - How does Windows 9x/NT manage the daylight saving time (if it does)? // |
||
29 | // - How does Windows Vista react to a RECYCLER\ folder on a NTFS device? // |
||
30 | // - How does Windows Vista react to a RECYCLED\ folder on a FAT device? // |
||
31 | // // |
||
32 | // Not analyzed yet! Please send me your trash folder contents for analyzing! // |
||
33 | // - Windows NT // |

||
37 | // Thanks to all these who have helped me solving coding problems. // |

38 | // Thanks to SEBA for sending in the Windows Vista trash structure files. // |

||
47 | |||
48 | Wichtig! Windows XP: InfoTip, IntroText und LocalizedString sind Resourcenangaben und müssen ausgelesen werden! |
||
49 | Testen: Wie reagiert Windows, wenn Bitbucket\C existiert, aber kein Wert 'Percent' hat? Mit der Standardeinstellung? |
||
50 | Bug: Windows 2000 bei bestehenden Windows 95 Partition: Recycler Filename ist dann Recycled und nicht Recycler! |
||
51 | bug? w95 recycled file hat immer selben löschzeitpunkt und größe? war die nicht verschieden? |
||
52 | Feature: win7 support |
||
53 | beachtet? bei leerem papierkorb auf fat ist weder info noch info2 vorhanden? |
||
54 | testen: auch möglich, einen vista papierkorb offline öffnen? |
||
55 | Problem: bei win95(ohne ie4) und win2000 gleichzeitiger installation: es existiert info UND info2!!! |
||
56 | Neue Funktionen: GetCurrentRecyclerIcon, GetFullIcon, GetEmptyIcon |
||
57 | Bei Vista gibt es manchmal einen c0000013 Fehler. (Auslesen des ganzen Papierkorbs) |
||
58 | Windows 7 miteinbeziehen! |
||
59 | Implement SETTER functions to every kind of configuration thing. (percentage etc) |
||
60 | Registry CURRENT_USER: Funktionen auch für fremde Benutzer zur Verfügung stellen? |
||
61 | |||
62 | - Future - |
||
63 | |||
64 | Demoapplikation: Dateien statt als Text als Explorer-Like? |
||
65 | Einzelne Elemente oder alle wiederherstellen oder löschen |
||
66 | Konfiguration für Laufwerke ändern etc |
||
67 | IconString -> TIcon Convertion functions |
||
68 | platzreservierung in mb-angabe berechnen |
||
69 | I don't know if there exists any API function which checks the state at any internal way. |
