12 | daniel-mar | 7 | // This unit is freeware, but please link to my website if you are using it! // |
8 | //////////////////////////////////////////////////////////////////////////////////// |
||
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. // |
||
25 | daniel-mar | 24 | // - Make it possible to empty the recycle bin of one specific drive! // |
12 | daniel-mar | 25 | // // |
26 | // Unknown! Do you know the answer? // |
||
27 | // - How does Windows 9x/NT manage the daylight saving time (if it does)? // |
||
28 | // - How does Windows Vista react to a RECYCLER\ folder on a NTFS device? // |
||
29 | // - How does Windows Vista react to a RECYCLED\ folder on a FAT device? // |
||
30 | // // |
||
31 | // Not analyzed yet! Please send me your trash folder contents for analyzing! // |
||
32 | // - Windows NT // |
||
33 | // - Windows CE? // |
||
34 | // - Windows 7 // |
||
35 | // // |
||
36 | // Thanks to all these who have helped me solving coding problems. // |
||
37 | // Thanks to SEBA for sending in the Windows Vista trash structure files. // |
||
38 | // Thanks to OMATA for testing the unit with Delphi 4. // |
||
39 | // Thanks to DEITYSOU for making a bugfix of DriveExists() // |

47 | Wichtig! Windows XP: InfoTip, IntroText und LocalizedString sind Resourcenangaben und müssen ausgelesen werden! |
||
48 | Testen: Wie reagiert Windows, wenn Bitbucket\C existiert, aber kein Wert 'Percent' hat? Mit der Standardeinstellung? |
||
49 | Bug: Windows 2000 bei bestehenden Windows 95 Partition: Recycler Filename ist dann Recycled und nicht Recycler! |
||
50 | bug? w95 recycled file hat immer selben löschzeitpunkt und größe? war die nicht verschieden? |
||
51 | beachtet? bei leerem papierkorb auf fat ist weder info noch info2 vorhanden? |
||
52 | testen: auch möglich, einen vista papierkorb offline öffnen? |
||
53 | Problem: bei win95(ohne ie4) und win2000 gleichzeitiger installation: es existiert info UND info2!!! |
||
54 | Implement SETTER functions to every kind of configuration thing. (percentage etc) |
||
55 | Registry CURRENT_USER: Funktionen auch für fremde Benutzer zur Verfügung stellen? |
||
23 | daniel-mar | 56 | Es sollte möglich sein, dass ein Laufwerk mehr als 1 Recycler beinhaltet -- behandeln |
12 | daniel-mar | 57 | |
58 | - Future - |
||
59 | |||
18 | daniel-mar | 60 | Demoapplikation: Dateien statt Text als Explorer-Like? |
12 | daniel-mar | 61 | Einzelne Elemente oder alle wiederherstellen oder löschen |
62 | Konfiguration für Laufwerke ändern etc |
||
63 | IconString -> TIcon Convertion functions |
||
64 | platzreservierung in mb-angabe berechnen |
||
65 | I don't know if there exists any API function which checks the state at any internal way. |
