You can.  What the help does not tell you, however, is that you need
to use the Win32 API GetParent() function to get the *corrent* HWND to
use from the dialog's Handle property.

You can.

That is the wrong Handle to use.  The event handler is a member of
your TForm class, so the 'this' pointer will point to the instance of
your TForm.  Thus, you are using the TForm's HWND as the parent window
instead of the dialog's HWND.  You need to use this instead:

    Button->ParentWindow = ::GetParent(SaveDialog1->Handle);
