Title: Delete files with Undo
Question: How can I delete files with undo (move to recycle bin)?
Answer:
{ Thanks to Poul Dige for this comment:
ALWAYS make sure, that FileName ends with two chr(0), i.e.
FileName := FileName+#0+#0;
If you want to process more than one file, the file names
should be separated by a single #0, e.g.
FileName := File1+#0+File2+#0.....+FileN+#0+#0; }
uses
ShellApi;
function DeleteFileWithUndo(FileName: string): boolean;
var
SHFileOpStruct: TSHFileOpStruct;
begin
FillChar(SHFileOpStruct, SizeOf(SHFileOpStruct), 0);
with SHFileOpStruct do
begin
{ specifies the operation }
wFunc := FO_DELETE;
{ specifies the filename to operate }
pFrom := PChar(FileName);
{ flags for controlling the operation }
{ Preserves undo information, Responds with yes to all
for any dialog box that is displayed, doesn't display a
progress dialog }
fFlags := FOF_ALLOWUNDO
or FOF_NOCONFIRMATION
or FOF_SILENT;
end;
{ returns true if successful, otherwise false }
result := (0 = ShFileOperation(SHFileOpStruct));
end;
