想請問各位大大，用IShellFolder.EnumObjects列舉出來的物件 如何判斷它是否為某些"特殊裝置"，或者有什麼方法能判別這些物件 這邊所指的特殊裝置如:(就是一些沒有實際路徑的物件) 我的電腦 控制台 網路芳鄰    //因為特定原因，我需要使用FindFirst去找出指定路徑下的檔案 //而上面我所指的這些特殊裝置並沒有實際路徑，我希望能避開這些物件 //至於網路芳鄰因沒有打算使用FindFirst，所以也希望能作判斷加以避開 //不知有沒有特定api能直接由列舉出的PItemIDList來判斷物件是否為網路資源 謝謝    ---------------------------------------------------------------  

 
  列舉程式碼大致如下：      try
    HR := ShellFolder.EnumObjects(0,
                                Flags,
                                EnumList);
    if HR <> S_OK then Exit;
    Result := EnumList.Next(1, ID, NumIDs) = S_OK;
  finally
    SetErrorMode(ErrMode);
  end;

參考看看:    

 
unit Unit1;    interface    uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls,ActiveX, ShlObj;    type
  TForm1 = class(TForm)
    ListBox1: TListBox;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;    function PathIsRootA(pszPath: PAnsiChar): BOOL; stdcall; external 'Shlwapi.dll';    var
  Form1: TForm1;    implementation    {$R *.dfm}    procedure TForm1.Button1Click(Sender: TObject);
var
  pShell, ShellFolder: IShellFolder;
  pidl: PITEMIDLIST;
  PMalloc: IMalloc;
  sName: string;
  EnumIDList: IEnumIDList;
  pceltFetched: ULONG;
  lpName: TStrRet;
  slDirectories: TStringList;
begin
  slDirectories := TStringList.Create;
  try
    SHGetDesktopFolder(ShellFolder);
    SHGetSpecialFolderLocation(0,CSIDL_DRIVES, pidl);
    SHGetMalloc(PMalloc);
    ShellFolder.BindToObject(pidl, nil, IID_IShellFolder, Pointer(pShell));
    pShell.EnumObjects(0,SHCONTF_FOLDERS, EnumIDList);
    while EnumIDList.Next(1,pidl, pceltFetched) = S_ok do
    begin
      pceltFetched := 0;
      lpName.uType := 0;
      pShell.GetDisplayNameOf(pidl, SHGDN_FORPARSING, lpName);
      sName := lpName.pOleStr;
      if PathIsRootA(Pchar(sName)) then
       slDirectories.Add(sName);
    end;
    ListBox1.Items.Assign(sldirectories);
  finally
    pMalloc._Release;
    pMalloc := nil;
    slDirectories.Free;
  end;
end;    end.
