mLipok Posted July 24, 2015 Share Posted July 24, 2015 (edited) Recently I was playing with, ObjEvent()I wanted to figure out how to properly use this function.I was puzzled about ie.au3 still generates notification about not registered error handler.So I make this test script:#include <ie.au3> #include <MsgBoxConstants.au3> ; Com Error Handler Global $g__oMyObjErrorHandler _Example() Func _Example() Local $sCurrentFunction = ObjEvent("AutoIt.Error") MsgBox(0, StringLen($sCurrentFunction), @error) ; Here I chceck ie.au3 behavior with this 3 followed line ; $g__oMyObjErrorHandler = ObjEvent("AutoIt.Error", '_Test_Com_ErrFunc') ; $g__oMyObjErrorHandler = ObjEvent("AutoIt.Error", _Test_Com_ErrFunc) ; _IEErrorHandlerRegister() Local $obj = _IECreate() $obj.fireErrEvent EndFunc ;==>_Example Func _Test_Com_ErrFunc() Local $sCurrentErrorHandler = ObjEvent("AutoIt.Error") Local $sInfo = _ '$sCurrentErrorHandler = ' & $sCurrentErrorHandler & @CRLF & _ 'IsString($sCurrentErrorHandler) = ' & IsString($sCurrentErrorHandler) & @CRLF & _ 'StringLen($sCurrentErrorHandler) = ' & StringLen($sCurrentErrorHandler) & @CRLF & _ 'IsFunc($sCurrentErrorHandler) = ' & IsFunc($sCurrentErrorHandler) & @CRLF & _ '' MsgBox(0, '$sInfo', $sInfo) EndFunc ;==>_Test_Com_ErrFunc And starts analysis.After all I made this function:; #INTERNAL_USE_ONLY# =========================================================================================================== ; Name...........: __IE_IsObjEventRegistered ; Description ...: to properly chceck if is any Error Handler registered ; Author ........: mLipok ; Modified ......: ; =============================================================================================================================== Func __IE_IsObjEventRegistered() Local $sCurrentErrorHandler = ObjEvent("AutoIt.Error") Return _ ; ( _ IsFunc($sCurrentErrorHandler) _ ; if there is any error handler defined as function Or _ ; or (IsString($sCurrentErrorHandler) And StringLen($sCurrentErrorHandler) > 0) _ ; if there is any error handler defined as function name (is string with length >0 ) EndFunc ;==>__IE_IsObjEventRegistered and modified this:; #INTERNAL_USE_ONLY# =========================================================================================================== ; Name...........: __IEInternalErrorHandlerRegister ; Description ...: to be called on error ; Author ........: Dale Hohm ; Modified ......: mLipok ; =============================================================================================================================== Func __IEInternalErrorHandlerRegister() If Not __IE_IsObjEventRegistered() Then ; We've got trouble... User COM Error handler assigned without using _IEUserErrorHandlerRegister Return SetError($_IEStatus_GeneralError, 0, False) EndIf $__g_oIEErrorHandler = ObjEvent("AutoIt.Error", "__IEInternalErrorHandler") If IsObj($__g_oIEErrorHandler) Then Return SetError($_IESTATUS_Success, 0, True) Else $__g_oIEErrorHandler = "" Return SetError($_IEStatus_GeneralError, 0, False) EndIf EndFunc ;==>__IEInternalErrorHandlerRegister And now I think it should work as it should works - properly.am I right ?btw.I be have further related question after when I get answers.
