SendMessage to Unidentified Edit Box?

[Trope]

I have a program window with 2 EDIT boxes. They appear not to be given a resource ID (somehow).

Here is a dump of the one I need from Olly:

Code Select Expand



004012A7  /$ 6A 00          PUSH 0                                   ; /lParam = NULL
004012A9  |. FF35 44204000  PUSH DWORD PTR DS:[402044]               ; |hInst = 00400000
004012AF  |. 6A 00          PUSH 0                                   ; |hMenu = NULL
004012B1  |. FF75 08        PUSH DWORD PTR SS:[EBP+8]                ; |hParent
004012B4  |. 6A 14          PUSH 14                                  ; |Height = 14 (20.)
004012B6  |. 68 EA000000    PUSH 0EA                                 ; |Width = EA (234.)
004012BB  |. 6A 05          PUSH 5                                   ; |Y = 5
004012BD  |. 6A 23          PUSH 23                                  ; |X = 23 (35.)
004012BF  |. 68 00000050    PUSH 50000000                            ; |Style = WS_CHILD|WS_VISIBLE
004012C4  |. 6A 00          PUSH 0                                   ; |WindowName = NULL
004012C6  |. 68 F1204000    PUSH pDBillin.004020F1                   ; |Class = "EDIT"
004012CB  |. 68 00020000    PUSH 200                                 ; |ExtStyle = WS_EX_CLIENTEDGE
004012D0  |. E8 3E010000    CALL <JMP.&USER32.CreateWindowExA>       ; \CreateWindowExA




From a different application I am trying to send a WM_SETTEXT message to the SECOND edit box.

Since there is no unique ID, how would I do this?

I THINK this will grab the first Edit Box:

Code Select Expand



invoke FindWindowEx, targethandle, 0, ADDR szEdit, NULL



but...

I need a handle to the SECOND one in the Window.

Is there a way to enumerate through them or something? Or am I again missing an easy solution?

Thanks to all.

EnumChildWindows did it.
