Delphi - how to get a list of all files of directory

Question

I am working with delphi, I want a list of all files of a directory when I execute openpicturedialog.

i.e., When open dialog is executed and i select one file from it, I want the list of all files from the directory of selected file.

You can even suggest me for getting directory name from FileName property of TOpenDialog
Thank You.

@Himadri, the primary objective of the OpenPictureDialog is not select an directory, anyway if you are using this dialog with another purpose you can try this code.

Var
  Path    : String;
  SR      : TSearchRec;
  DirList : TStrings;
begin
  if OpenPictureDialog1.Execute then
  begin
    Path:=ExtractFileDir(OpenPictureDialog1.FileName); //Get the path of the selected file
    DirList:=TStringList.Create;
    try
          if FindFirst(Path + '*.*', faArchive, SR) = 0 then
          begin
            repeat
                DirList.Add(SR.Name); //Fill the list
            until FindNext(SR) <> 0;
            FindClose(SR);
          end;

     //do your stuff

    finally
     DirList.Free;
    end;
  end;

end;
