AW: Wallpaper und Windows 8+

  Alt 11. Okt 2018, 23:39
Code:
' Copyright © 2013 Dwight Grant. All rights reserved.
' Filename: Win8_WP_Curr_Image_Name-Folder.txt
' Version: 2.00.01
'
' Purpose: If (in Windows 8) running Desktop Wallpaper Slideshow:
'             To Display the Name of the Current Image (opt=1)
'                                     or
'             Display the Folder with the Current Image Selected (opt=2).
'
' This script reads and decodes registry key:
'     HKEY_CURRENT_USER\Control Panel\Desktop\TranscodedImageCache
'         and displays results on desktop
'
' How to Use -  Creation:
' 1. Save Text file at a location of your choosing.
' 2. Open Text file with "Notepad" and "Save As" same name with ".vbs" file type.
'      You will now have both "Win8_WP_Curr_Image_Name-Folder.txt" and
'                              "Win8_WP_Curr_Image_Name-Folder.vbs".
' 3. Create desktop shortcut to "Win8_WP_Curr_Image_Name-Folder.vbs".
'
' Operation: Double Click on the Desktop Icon Created,
'              Executes "Microsoft Windows Based Script Host" and
'                will display full path name of Wallpaper file.
'
'***  Author: Dwight Grant **** Revised: Nov. 27, 2013 ***
' based upon idea from Ramesh Srinivasan in program "WPTargetDir.vbs" for Win 7
' & revisions suggested by FleetCommand.
'
' ***  Please note: It is not unicode compliant - Path name needs to be ASCII to display properly.
'       If anyone has sugestions as to how to make it compliant, please explain, and I will try to
'            incorporate it into the next version.

dieses .vbs script funktioniert auf fremdrechner.

edit
so habe ich es nun in delphi
Delphi-Quellcode:
procedure TForm1.Button1Click(Sender: TObject);
const
  CDataValue: string = 'TranscodedImageCache';
  CKeyName: string = 'Control Panel\Desktop\';
var
  regist: TRegistry;
  KeyExists: boolean;
  vSize, p, i: integer;
  tmpStr, tmp: string;
  arr: array of byte;
begin
// Edit1.Text := GetWallpaperBitmap;
  regist := TRegistry.Create;
  try
    regist.RootKey := HKEY_CURRENT_USER;
    try
      KeyExists := regist.OpenKey(CKeyName, false);
      if (KeyExists) then
      begin
        vSize := regist.GetDataSize(CDataValue);
        if (vSize > 0) then
        begin
          tmpStr := '';
          SetLength(arr, vSize);
          regist.ReadBinaryData(CDataValue, arr[0], vSize);
          for i := 23 to vSize -1 do
              if arr[i] > 31 then tmpStr := tmpStr + Chr(arr[i]);
          Edit1.Text := tmpStr;
        end;
      end;
    except
      regist.CloseKey;
    end
  finally
    regist.Free;
  end;
end;

Wenn ein unerwarteter Fehler aufgetreten ist, frage ich mich immer, welche Fehler erwartet wurden...
