![]() ![]() The primary role of Windows hooks is to monitor the message traffic of some thread. A detailed description of this technique can be found here. Instead of writing a separate DLL, copy your code to the remote process directly-via WriteProcessMemory-and start its execution with CreateRemoteThread.Put your code into a DLL and map the DLL to the remote process using the CreateRemoteThread & LoadLibrary technique.Put your code into a DLL then, map the DLL to the remote process via windows hooks. ![]() In general, there are three possibilities to solve this problem: So, our problem reduces to the following: How to get ::SendMessage( hPwdEdit, WM_GETTEXT, nMaxChars, psBuffer ) Įxecuted in the address space of another process. Only the process that “owns” the password control can get its contents via WM_GETTEXT. If the edit control belongs to another process and the ES_PASSWORD style is set, this approach fails. This also applies to edit controls, except in one special case. To “read” the contents of any control-either belonging to your application or not-you generally send the WM_GETTEXT message to it. But first, let me review the problem briefly, just to make sure we’re all on the same page. Is there any other way to make such a utility? Yes, there is. Several password spy tutorials have been posted to CodeGuru, but all of them rely on Windows hooks.
