Windows will not let the user or your program undo file delete operations that your perform using low-level functions such as
DeleteFile() from your program. Following function, however, will delete a file with the ability to undo (recycle) by sending the file to the "
Recycle Bin."
uses ShellAPI;
function DeleteFileWithUndo(
sFileName : string )
: boolean;
var
fos : TSHFileOpStruct;
begin
FillChar( fos, SizeOf( fos ), 0 );
with fos do
begin
wFunc := FO_DELETE;
pFrom := PChar( sFileName );
fFlags := FOF_ALLOWUNDO
or FOF_NOCONFIRMATION
or FOF_SILENT;
end;
Result := ( 0 = ShFileOperation( fos ) );
end; |
To delete a file, simply pass the file name to
DeleteFileWithUndo() and it will return
True if the operation was successful.
