How to show Properties Dialog for multiple Files with different locations - delphi

Question

HI. Could you help me please. How to show standard windows "File Properties" dialog for a list of files, but the files have different location?
For ex:
D:\
D:\Pictures
E:\Text.txt
I've found an example and it works fine:
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);
type
PArrayOfPItemIDList = ^TArrayOfPItemIDList;
TArrayOfPItemIDList = array[0..0] of PItemIDList;
var
Data: IDataObject;
begin
if Files.Count = 0 then Exit;
Data := GetFileListDataObject(Files);
SHMultiFileProperties(Data, 0);
end;
But when I pass a Drive letter, it shows an empty "File Properties" dialog:
///
SL.Add('D:\');
ShowFileProperties(SL, Handle);
I have another example:
Procedure ShowFileProperties(Const filename: String);
Var
sei: TShellExecuteinfo;
Begin
FillChar(sei,sizeof(sei),0);
sei.cbSize := sizeof(sei);
sei.lpFile := Pchar(filename);
sei.lpVerb := 'Properties';
sei.fMask := SEE_MASK_INVOKEIDLIST;
ShellExecuteEx(#sei);
End;
It also shows "File Properties" Dialog , but unfortunately for one file only. How to pass multiple files with different locations in this example???
I also found another source which has the procedures I need but they require files to be located in the same folder. Here is a link: link text

Answer 1

I would take a look at the code example found here. I think you should be able to use that idea to pass in multiple file paths.
