Internet Explorer_Server class window

[gigemboy]

The code to get the text doesnt work.. i returns a zero value. The code I have so far is below, all the handles pull nonzerovalues. The SendMessage statements return 0.

hWndTmp = FindWindow("IMClass", "SymbolType")
        hWndChild = FindWindowEx(hWndTmp, 0, "YHTMLContainer", vbNullString)
        hWndIEServer = FindWindowEx(hWndChild, 0, "Internet Explorer_Server", vbNullString)
        Dim lLen As Long
        Dim IElen As Long
        Dim sText As String
        lLen = SendMessage(hWndIEServer, WM_GETTEXTLENGTH, 0, IElen)
        SendMessage(hWndIEServer, WM_GETTEXT, lLen + 1, sText)

Im guessing the code won't work because it is some sort of HTML object. Anyone know how to pull text from the Internet Explorer_Server class window? The same class is used as the main window in Internet Explorer, so surely someone out there has done it.

I now am pulling the HTML Object out of the window, but I am still getting a blank document. Here is some of the code :

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim objDoc As IHTMLDocument
        hWndTmp = FindWindow("IMClass", "*window title*")
        hWndChild = FindWindowEx(hWndTmp, 0, "YHTMLContainer", vbNullString)
        hWndIEServer = FindWindowEx(hWndChild, 0, "Internet Explorer_Server", vbNullString)
        MsgBox(hWndIEServer)
        If hWndIEServer > 0 Then
            objDoc = WindowDOM(hWndIEServer)
            If Not (objDoc Is Nothing) Then
                MsgBox(objDoc.body.innerText)
            End If
        End If
    End Sub

The Associated Functions and structures are below :

Declare Function ObjectFromLresult Lib "oleacc.dll" ( _
        ByVal lResult As Int32, _
        ByVal riid As UUID, _
        ByVal wParam As Int32, _
        ByVal ppvObject As Object) As Int32
 
    Declare Function RegisterWindowMessage Lib "user32.dll" Alias "RegisterWindowMessageA" ( _
        ByVal lpString As String) As Int32
 
    Declare Function SendMessageTimeout Lib "user32.dll" Alias "SendMessageTimeoutA" ( _
        ByVal hWnd As Int32, _
        ByVal Msg As Int32, _
        ByVal wParam As Int32, _
        ByVal lParam As Int32, _

    Public Structure UUID
        Public Data1 As Long
        Public Data2 As Integer
        Public Data3 As Integer
        Public Data4() As Byte
    End Structure
    Public Function WindowDOM(ByVal hWnd As Int32) As IHTMLDocument
        Dim typUUID As UUID, lngRes As Int32, lngMsg As Int32
        lngMsg = RegisterWindowMessage("WM_HTML_GETOBJECT")
        'MsgBox(lngMsg.ToString & " lngmessage")
        If lngMsg <> 0 Then
            Call SendMessageTimeout(hWndIEServer, lngMsg, 0, 0, SMTO_ABORTIFHUNG, 1000, lngRes)
            MsgBox(lngRes.ToString)
            If lngRes <> 0 Then
                With typUUID
                    .Data1 = &H626FC520
                    .Data2 = &HA41E
                    .Data3 = &H11CF
                    .Data4(0) = &HA7
                    .Data4(1) = &H31
                    .Data4(2) = &H0
                    .Data4(3) = &HA0
                    .Data4(4) = &HC9
                    .Data4(5) = &H8
                    .Data4(6) = &H26
                    .Data4(7) = &H37
                End With
                Call ObjectFromLresult(lngRes, typUUID, 0, WindowDOM)
            End If
        End If
    End Function

The code all runs without errors, however the "objDoc = WindowDOM(hWndIEServer)" posted on the button click is a blank document, because the If statement isnt ran.

The SendMessageTimeout function call in the WindowDom function brings back a message of 0, which is where i think the holdup is. I can feel im getting real close... anyone know of something i can try??
