The password of the Windows system is very fragile, because all passwords are entered, it is very safe to see this, because the average person does not understand what is ******, but In fact, it is easy to see the content under *******, the working principle is as follows: Windows is a window-based message-driven job system, each window has its own properties, where the attribute of the password window is ES_PASSWORD, so we can use the enumeration of the sub-window ENUMCHILDWINDOWS to find out all the subsets in the system, check their properties getWindowlong, if es_password is a password window, then use SendMessage () to get the window title, that is, ***** * The real content under * ==================================================================================================================================================================================================================================================================00 Var hcount: integer; // This is a window response function, pay attention: Result: = true is important, because only this can continue to scan all sub-window Function LpenumFunc (hwnd: integer; uint: integer): boolean; stdcall; var hw , HS, Wlong: INTEGER; SBUF, SB2: Array [0..256] of char; sb1: string; begin // Get window properties Wlong: = getWindowlong (hwnd, gwl_style); // If the attribute is ES_PASSWORD Password window IF (Wlong and ES_PASSWORD) <> 0 THEN BEGIN INC (hWND, HWND, WM_GETTEXT, 40, Integer (@sbuf)); // Set the password StrPCopy (SBUF) , format ('[password% d] =% s', [hcount, sbuf])); // Displays the password end; // RESULT continues to scan the next sub-window RESULT: = true; end; begin LP: = 0; hcount: = 0; // enumerate child windows, GetDesktopWindow to handle EnumChildWindows (GetDesktopWindow, @ lpEnumFunc, lp) get desktop; end // Author: Jian-Hua Ni Copyright (C) 2001-6-27 Allright Reserved. .
