Problem regarding automating embedded internet explorer_server

[johnz]

Hi Guys,

I need to access an embedded instance of internet explorer. I tried using the _IEAttach method passing the Window name and "embedded" as the mode but no success with that. So i broke up the calls to internal functions of IE.au3 and found that a call to function DllCall is returning an error. Here's what my code looks like:

$handle = WinGetHandle("Window Name")

_IEErrorHandlerRegister()

WinActivate($handle)

$h_Ctrl = ControlGetHandle($handle, "", "[Class:Internet Explorer_Server]")

$o_IE = ___IEControlGetObjFromHWND($h_Ctrl)

MsgBox(0, "Error Status", @error)

Inside the ___IEControlGetObjFromHWND function:

Func __IEControlGetObjFromHWND(ByRef $hWin)

DllCall("ole32.dll", "int", "CoInitialize", "ptr", 0)

Local Const $WM_HTML_GETOBJECT = __IERegisterWindowMessage("WM_HTML_GETOBJECT")

Local Const $SMTO_ABORTIFHUNG = 0x0002

Local $lResult, $typUUID, $aRet, $oIE

__IESendMessageTimeout($hWin, $WM_HTML_GETOBJECT, 0, 0, $SMTO_ABORTIFHUNG, 1000, $lResult)

MsgBox(0, "Result", $lResult)

$typUUID = DllStructCreate("int;short;short;byte[8]")

DllStructSetData($typUUID, 1, 0x626FC520)

DllStructSetData($typUUID, 2, 0xA41E)

DllStructSetData($typUUID, 3, 0x11CF)

DllStructSetData($typUUID, 4, 0xA7, 1)

DllStructSetData($typUUID, 4, 0x31, 2)

DllStructSetData($typUUID, 4, 0x0, 3)

DllStructSetData($typUUID, 4, 0xA0, 4)

DllStructSetData($typUUID, 4, 0xC9, 5)

DllStructSetData($typUUID, 4, 0x8, 6)

DllStructSetData($typUUID, 4, 0x26, 7)

DllStructSetData($typUUID, 4, 0x37, 8)

$aRet = DllCall("oleacc.dll", "int", "ObjectFromLresult", "int", $lResult, "ptr", DllStructGetPtr($typUUID), _

"int", 0, "idispatch_ptr", "")

MsgBox(0, "Error", @error)

If IsObj($aRet[4]) Then

$oIE = $aRet[4].Script ()

; $oIE is now a valid IDispatch object

Return $oIE.document.parentwindow

Else

SetError(1)

Return 0

EndIf

EndFunc

After the DllCall("oleacc.dll", "int", "ObjectFromLresult", "int", $lResult, "ptr", DllStructGetPtr($typUUID), "int", 0, "idispatch_ptr", ""), i placed a msgbox to get the error which as it turns out is 2. According to the help file, @error = 2 unknown "return type".

So whats going wrong here? I am actually trying to get control of the embedded browser so that I can navigate around and get/post data.

Any help in this regard will be highly appreciated.

Thanks.
