How I can get the text of a textbox that is on other app?

[softwareguy74]

Okay, I've got this working to a point. Now, on the screen where I want to read from a particular textbox, there are more than one textbox on the screen with the same Class name. How do I specify that I want to read from a certain textbox? I'm using the following code to read the text, but again, it's reading from the first textbox on the screen, I want to read from the second one.

If hwnd Then
        '-- grab text out of textbox
        hwnd2 = FindWindowEx(hwnd, 0, "Edit", vbNullString)
        If hwnd2 Then
            SetForegroundWindow hwnd
            ret = SendMessage(hwnd2, WM_GETTEXTLENGTH, 0, 0)
            buffer = Space(ret)
            ret = SendMessageByString(hwnd2, WM_GETTEXT, ret + 1, buffer)
            MsgBox buffer
        End If
    End If
