Hi @ all

Does someone of you know how to read the content of a foreign edit-control? Foreign means, that this control doesn't belong to my program. If the mouse moves over an edit-control the program should read it out. That's all. Getting the handle of this control was no problem. But I can't read the text with WM_GETTEXT message. The editmessage doesn't work too.

I hope you could help me

Did you try SendMessage, hwnd, WM_GETTEXT,,?

PostMessage, GetWindowText, etc will not work, but SendMessage should work.

Unless the edit box has custom handling (ie not default) for the WM_GETTEXT message, in which case you are out of luck.

Marwin, this wouldn't happen to be a password field would it? :eek: :grin:

This method doesn't work under 2k and xp...
For NT systems, you can consider using remote thread instead.

Password Revealer

This method doesn't work under 2k and xp...

If you mean SendMessage,,WM_GETTEXT,,? it works!
At least under w2k. I did it many times.

Marwin, if you still unsuccessful with SendMessage and PassvordReveler did not help,
you have to hook your edit control. I've attached some ex.
Can't remember if i tested it under nt, but anyway it should work.
Run Target.exe, then RTH.exe, and play with Get/Set/Spy buttons.
Hope this helps.

Four-F: remotetexthunter works on NT4SP6 :alright: - nice!

Ok, sorry guys. Sending a WM_GETTEXT message works very well. But not if you're sending it to the wrong window. The hook procedure returns the handle in wParam, and I sent the message to lParam. :stupid: Now it works great (under Win98SE).

Maybe you can look at a program source of one of our members, Vom-Bonjour... it does exactly what you want.
The source are released both on the MASM32 package as an example, and in Iczelion's website (Get&Set)...

Four-F, I meant editboxes with the ES_PASSWORD bit set. :)
Password Revealer works fine and I'd say you did it the best way; approaches other than hooking would fail in one Windows version or another.

In case any of you managed to spot what bomb01 wrote about it not being possible to read password fields in 2K and XP, you *can* read it by sending it a WM_GETTEXT, but it is already encrypted so it will mean nothing to you.
