22 | // Needs Delphi 4 or higher. If you are using Delphi 4 or 5, you can not use the // |

24 | // Warning! This is a platform unit. // |

25 | // // |
||
26 | // To do! Can you help? // |
||
67 | daniel-mar | 27 | // - Win7 : Drive GUIDs // |
28 | // - Win7 : Absolute vs. Relative size limitations // |
||
12 | daniel-mar | 29 | // - WideString-Support (input/output) // |
30 | // - Always do EOF before reading anything? // |
||
31 | // - Is it possible to identify a Vista-file that is not named $Ixxxxxx.ext? // |
||
32 | // - RecyclerGetInfofiles() check additionally for removable device? // |
||
33 | // RecyclerIsValid() is false. // |
||
25 | daniel-mar | 34 | // - Make it possible to empty the recycle bin of one specific drive! // |
12 | daniel-mar | 35 | // // |
36 | // Unknown! Do you know the answer? // |
||
37 | // - How does Windows 9x/NT manage the daylight saving time (if it does)? // |
||
38 | // - How does Windows Vista react to a RECYCLER\ folder on a NTFS device? // |

||
51 | |||
67 | daniel-mar | 52 | - Wichtig! Windows XP: InfoTip, IntroText und LocalizedString sind Resourcenangaben und müssen ausgelesen werden! |
53 | - Testen: Wie reagiert Windows, wenn Bitbucket\C existiert, aber kein Wert 'Percent' hat? Mit der Standardeinstellung? |
||
54 | - Bug: Windows 2000 bei bestehenden Windows 95 Partition: Recycler Filename ist dann Recycled und nicht Recycler! |
||
55 | - bug? w95 recycled file hat immer selben löschzeitpunkt und größe? war die nicht verschieden? |
||
56 | - beachtet? bei leerem papierkorb auf fat ist weder info noch info2 vorhanden? |
||
57 | - testen: auch möglich, einen vista papierkorb offline öffnen? |
||
58 | - Problem: bei win95(ohne ie4) und win2000 gleichzeitiger installation: es existiert info UND info2!!! |
||
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 | - Es sollte möglich sein, dass ein Laufwerk mehr als 1 Recycler beinhaltet -- behandeln |
||
12 | daniel-mar | 62 | |
67 | daniel-mar | 63 | === Future Ideas === |
12 | daniel-mar | 64 | |
67 | daniel-mar | 65 | - Demoapplikation: Dateien statt Text als Explorer-Like (TListView)? |
66 | - Einzelne Elemente oder alle wiederherstellen oder löschen |
||
67 | - Konfiguration für Laufwerke ändern etc |
||
68 | - IconString -> TIcon Convertion functions |
||
69 | - platzreservierung in mb-angabe berechnen |
||
70 | - I don't know if there exists any API function which checks the state at any internal way. |
||
71 | - copy/move files from recyclebin |
