library Properties;{ Important note about DLL memory management: ShareMem must be the  first unit in your library's USES clause AND your project's (select  Project-View Source) USES clause if your DLL exports any procedures or  functions that pass strings as parameters or function results. This  applies to all strings passed to and from your DLL--even those that  are nested in records and classes. ShareMem is the interface unit to  the BORLNDMM.DLL shared memory manager, which must be deployed along  with your DLL. To avoid using BORLNDMM.DLL, pass string information  using PChar or ShortString parameters. }uses  Windows,  Dialogs,  SysUtils,  Classes, ActiveX, ShlObj, ComObj;{$R *.res}function SHMultiFileProperties(pDataObj: IDataObject; Flag: DWORD): HRESULT;stdcall; external 'shell32.dll';function GetFileListDataObject(Files: TStrings): IDataObject;type  PArrayOfPItemIDList = ^TArrayOfPItemIDList;  TArrayOfPItemIDList = array[0..0] of PItemIDList;var  Malloc: IMalloc;  Root: IShellFolder;  p: PArrayOfPItemIDList;  chEaten, dwAttributes: ULONG;  i, FileCount: Integer;begin  Result := nil;  FileCount := Files.Count;  if FileCount = 0 then Exit;    OleCheck(SHGetMalloc(Malloc));  OleCheck(SHGetDesktopFolder(Root));  p := AllocMem(SizeOf(PItemIDList) * FileCount);  try    for i := 0 to FileCount - 1 do    try      if not (DirectoryExists(Files[i]) or FileExists(Files[i])) then Continue;      OleCheck(Root.ParseDisplayName(GetActiveWindow,                                    nil,                                    PWideChar(WideString(Files[i])),                                    chEaten,                                    p^[i],                                    dwAttributes));      except      end;    OleCheck(Root.GetUIObjectOf(GetActiveWindow,                                  FileCount,                                  p^[0],                                  IDataObject,                                  nil,                                  Pointer(Result)));          finally        for i := 0 to FileCount - 1 do        begin          if p^[i] <> nil then Malloc.Free(p^[i]);        end;        FreeMem(p);      end;    end;    procedure ShowFileProperties(Files: TStrings; aWnd: HWND);typePArrayOfPItemIDList = ^TArrayOfPItemIDList;TArrayOfPItemIDList = array[0..0] of PItemIDList;varData: IDataObject;begin  if Files.Count = 0 then Exit;  Data := GetFileListDataObject(Files);  SHMultiFileProperties(Data, 0);end;function SplitString(const source, ch: string): TStringList;var  temp, t2: string;  i: integer;begin  result := TStringList.Create;  temp := source;  i := pos(ch, source);  while i <> 0 do  begin    t2 := copy(temp, 0, i - 1);    if (t2 <> '') then      result.Add(t2);    delete(temp, 1, i - 1 + Length(ch));    i := pos(ch, temp);  end;  result.Add(temp);end;procedure ShowProperties(AFiles: PChar); stdcall;var  oList:TStrings;begin  oList:= SplitString(AFiles, ';');  ShowFileProperties(oList, 0);end;exports  ShowProperties name 'ShowProperties';beginend.
