trying to understand error handler

[gcue]

after registering these error handlers:

$COM_Error = ObjEvent("AutoIt.Error", "COM_Error")
_IEErrorHandlerRegister()

Func COM_Error()

    MsgBox(262144, "Dashboard", $COM_Error.description & @CRLF & _
            "" & @CRLF & _
            "Script Line: " & $COM_Error.scriptline)

EndFunc   ;==>COM_Error

i get weird errors. i get an error for this line upon script startup

$noteslink_input = GUICtrlCreateInput("", 120, 40, 280, 20)

after running this function:

Func Links_Altiris()
    $oIE = _IECreate("http://altirisams/Altiris/NS/", 0)
EndFunc   ;==>Links_Altiris

i get an error for this line AND a blank line:

$fcolor_btn = GUICtrlCreateButton("", 120, 153, 40, 20)

i also get this in the console when i run the function above (which confuses me - says to register ierrorhandlerregister.. uhh thought i did!) :

--> IE.au3 V2.4-0 Error from function _IEPropertySet, $_IEStatus_GeneralError (Error Handler Not Registered - Check existance of error function)

--> IE.au3 V2.4-0 Warning from function internal function __IEIsObjType, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

--> IE.au3 V2.4-0 Warning from function internal function __IEIsObjType, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

--> IE.au3 V2.4-0 Warning from function _IELoadWait, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

thank you in advance for your help Edited April 7, 2010 by gcue

IE error handler uses the object event... use one or the other only

;===============================================================================
;
; Function Name:   _IEErrorHandlerRegister()
; Description:      Register and enable a user COM error handler
; Parameter(s):     $s_functionName - String variable with the name of a user-defined COM error handler
;                                     defaults to the internal COM error handler in this UDF

; Return Value(s):  On Success  - Returns 1
;                   On Failure  - Returns 0 and sets @ERROR
;                   @ERROR      - 0 ($_IEStatus_Success) = No Error
;                               - 1 ($_IEStatus_GeneralError) = General Error

Func _IEErrorHandlerRegister($s_functionName = "__IEInternalErrorHandler")
    $sIEUserErrorHandler = $s_functionName
    $oIEErrorHandler = ""
    $oIEErrorHandler = ObjEvent("AutoIt.Error", $s_functionName)
    If IsObj($oIEErrorHandler) Then
        SetError($_IEStatus_Success)
        Return 1
    Else
        __IEErrorNotify("Error", "_IEPropertySet", "$_IEStatus_GeneralError", _
                "Error Handler Not Registered - Check existance of error function")
        SetError($_IEStatus_GeneralError, 1)
        Return 0
    EndIf
EndFunc   ;==>_IEErrorHandlerRegister

i went ahead and used this as myerrorfunction instead of the ie one

(id like to track the line number and description)

Func Custom_COM_Error()

    MsgBox(262144, "Dashboard", $Custom_COM_Error.Description & @CRLF & _
            "" & @CRLF & _
            "Script Line: " & $Custom_COM_Error.ScriptLine)

    $COM_Error = 1

EndFunc   ;==>Custom_COM_Error

seems to work better now that im only registering ONE error function =)

i still get this error when i run _iecreate (but functions works ok)

--> IE.au3 V2.4-0 Warning from function internal function __IEIsObjType, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

[gcue]

if i run iecreate with these switches (0, 1, 0, 1)

0-dont attach

1-browser is visible

0-return immediately, dont wait for page to load

1-bring window to focus

i get this error:

--> IE.au3 V2.4-0 Warning from function internal function __IEIsObjType, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

with these switches (0, 0, 1, 0) on iecreate

0-dont attach

1-browser is NOT visible

0-wait for page to load

0-dont bring window to focus

i get these errors:

--> IE.au3 V2.4-0 Warning from function internal function __IEIsObjType, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

--> IE.au3 V2.4-0 Warning from function _IELoadWait, Cannot register internal error handler, cannot trap COM errors (Use _IEErrorHandlerRegister() to register a user error handler)

and an error on line 4257 which i think is from the ie.au3 udf

$oTemp = $o_object.document

Please study the Remarks in the documentation for _IEErrorHandlerRegister. It explains all of this in detail.
