Ok I've seen a few threads over the last few months about using "EnumerateWindow" or "FindWindow" to get the handle to another window...

My question is this (using a recent thread)
Say I want to get the text from a window (AIM) I have open...
You can do this:
iMClass db "AIM_IMessage",0
invoke FindWindow, addr iMEditClass, 0

Now this would only get one window (you could enumerate all of these instances, but this is just a simple example)...

But where do you go from here?

How do you access the IM edit box (is there some standard way to do this...

I know if you have a hook you can basically change everything, but can it be done without having the user having to select everything?

Basically I was trying to see if I could write an simple application that would send a message to all active windows (saying "Goodbye" or whatever) and got stuck on this first part :(

Any help is appreciated

Maybe sending WM_GETTEXT/SETTEXT would do it

use a window spy to get the Window Control ID and maybe the parent window

then use GetDlgItem to get the handle to that window.
or FindWindowEx first if it has a parent window

i attached the program Spy & Capture, the author's site seems to be down.

This is my code so far:

invoke FindWindow, addr iMClass, 0
mov hWndAim, 000008A8h
mov hWndAimButton, 00000b28h
invoke SendMessage,hWndAim,WM_GETTEXTLENGTH,0,0
invoke SendMessage,hWndAim,WM_SETTEXT,0,addr iMEditClass
Invoke SendMessage, hWndAimButton, WM_LBUTTONDOWN, 0, 0
Invoke SendMessage, hWndAimButton, WM_LBUTTONUP, 0, 0

FindWindow really doesn't do a whole lot in this example because I ended up just hardcoding the values ...

The problem is that the values can't be hardcoded in reallife :( Meaning the valu for the edit box and the send button change with each instance of the application

So the question is now?

Given a window with alot of buttons and edit boxes how do you pick the right one or is there a command to narrow this down?

Help would seriously be appreciated

Use the Spy to get the ControlID values, not the handles, because the controlid's are (always) static.

then use invoke GetDlgItem, hWnd, ControlID to get the handle..

;assuming the controlid of the button is 1000 (just as an example)

invoke FindWindow, addr iMClass, 0
mov hWndAim, eax ;not sure if this is right, because i dont have aim
invoke GetDlgItem, hWndAim, IDC_AIMBUTTON
mov hWndAimButton, eax
Invoke SetWindowText, hWndAimButton, CTEXT("Test")
