\nToday we’ll do a scripting version of\n\nan old C++ program<\/a>:\nPrinting information about the items in the Recycle Bin.\n(How you wish to act on the information is up to you.)\n<\/p>\n

\n\nThis is a pattern we’ve seen a lot<\/a>.\nBind to a folder, enumerate its contents,\nextract properties.\n<\/p>\n

\nvar shell = new ActiveXObject(\"Shell.Application<\/a>\");\nvar recycleBin = shell.NameSpace(10); \/\/ CSIDL_BITBUCKET\nvar items = recycleBin.Items();\nfor (var i = 0; i < items.Count; i++) {\n  var item = items.Item(i);\n  WScript.StdOut.WriteLine(item.Name);\n  WScript.StdOut.WriteLine(item.ExtendedProperty(\n                                \"System.Recycle.DeletedFrom\"));\n  WScript.StdOut.WriteLine(item.ExtendedProperty(\n                                \"System.Recycle.DateDeleted\"));\n  WScript.StdOut.WriteLine(item.Size);\n}\n<\/pre>\n
\nWow, that was way easier than doing it in C++!\n<\/p>\n
\nJust for fun, I’ll do it in C#, first as a straight port:\n<\/p>\n
\n\/\/ add a reference to shell32.dll\nclass Program {\n  public static void Main()\n  {\n    var shell = new Shell32.Shell();\n    var recycleBin = shell.NameSpace(10); \/\/ CSIDL_BITBUCKET\n    var items = recycleBin.Items();\n    for (var i = 0; i < items.Count; i++) {\n      var item = (Shell32.FolderItem2)items.Item(i);\n      System.Console.WriteLine(item.Name);\n      System.Console.WriteLine(item.ExtendedProperty(\n                                    \"System.Recycle.DeletedFrom\"));\n      System.Console.WriteLine(item.ExtendedProperty(\n                                    \"System.Recycle.DateDeleted\"));\n      System.Console.WriteLine(item.Size);\n    }\n  }\n}\n<\/pre>\n
\nWe have to cast to\nShell32.Folder­Item2<\/code> because the default interface\nfor the Item()<\/code> method is\nShell32.Folder­Item<\/code>,\nbut\nExtended­Property<\/code> is a method on\nShell32.Folder­Item2<\/code>.\nWe didn’t have to do this explicit cast in JavaScript\nbecause JavaScript is a dynamically-typed language.\n<\/p>\n
\nSo let’s use the dynamic<\/code> keyword to mimic that\nin C#.\nNote, however, that if you use dynamic<\/code>, then you\nmiss out on a lot of IntelliSense features.\n<\/p>\n
\nclass Program {\n  public static void Main()\n  {\n    var shell = new Shell32.Shell();\n    var recycleBin = shell.NameSpace(10); \/\/ CSIDL_BITBUCKET\n    var items = recycleBin.Items();\n    foreach (dynamic item in items) {\n      System.Console.WriteLine(item.Name);\n      System.Console.WriteLine(item.ExtendedProperty(\n                                    \"System.Recycle.DeletedFrom\"));\n      System.Console.WriteLine(item.ExtendedProperty(\n                                    \"System.Recycle.DateDeleted\"));\n      System.Console.WriteLine(item.Size);\n    }\n  }\n}\n<\/pre>\n
\nNow you can do things like list all the files deleted today\n<\/p>\n
\nclass Program {\n  public static void Main()\n  {\n    var today = DateTime.Today;\n    var shell = new Shell32.Shell();\n    var recycleBin = shell.NameSpace(10); \/\/ CSIDL_BITBUCKET\n    var items = recycleBin.Items();\n    foreach (dynamic item in items) {\n      if (item.ExtendedProperty(\"System.Recycle.DateDeleted\").Date\n                                                       == today) {\n        System.Console.WriteLine(item.name);\n      }\n    }\n  }\n}\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
