Question:
I would like to Check if the recycle bin is empty with application created with delphi. Can you help me?

Answer:
Checking recycle bin empty or not doesnt need big program, just simple function with ole object. Here the source code of the function:


uses
Activex, ShlObj, ComObj;
function RecycleBinIsEmpty: Boolean;
const
CLSID_IRecycleBin: TGUID = (D1: $645FF040; D2: $5081; D3: $101B;
D4: ($9F, $08, $00, $AA, $00, $2F, $95, $4E));
var
EnumIDList: IEnumIDList;
FileItemIDList: PItemIDList;
ItemCount: ULONG;
RecycleBin: IShellFolder;
begin
CoInitialize(nil);
OleCheck(CoCreateInstance(CLSID_IRecycleBin, nil, CLSCTX_INPROC_SERVER or
CLSCTX_LOCAL_SERVER, IID_IShellFolder, RecycleBin));
RecycleBin.EnumObjects(0,
SHCONTF_FOLDERS or
SHCONTF_NONFOLDERS or
SHCONTF_INCLUDEHIDDEN,
EnumIDList);
Result := EnumIDList.Next(1, FileItemIDList, ItemCount) <> NOERROR;
CoUninitialize;
end;
