Error Handling using IE.au3

[Vishal85]

I have created some scripts using IE.au3 but i havent implemented any good error handling logic yet. In case of any errors IE.au3 prints the errors in the console. I believe those errors are printed to console using __IEErrorNotify function. I want to use these error messages and insert those into a text file or an excel. Any ideas? Basically if error messages are generated from IE.au3 after accessing its functions, then i want to write them to a file.

I can take care of writing anything to a text file or an excel but please help me getting hold of these error messages generated from IE.au3.

Hi,

I think you want _IEErrorHandlerRegister.

#include <IE.au3>
 
 
_IEErrorHandlerRegister("_IEErrorHandler") ; register custom IE error handler
 
; lets see it in action
$oIE = _IECreate("http://example.com", 0, 0) ; create (hidden) IE object
ConsoleWrite("URL: " & $oIE.document.URL & @CRLF) ; print URL to console
ConsoleWrite("Nothing: " & $oIE.triggerErrorHere & @CRLF) ; trigger error by invoking non existing attribute
 
 
; custom IE error handler function
Func _IEErrorHandler()
    Local $sError = "!> IE COM Error" & @CRLF
    $sError &= "-> ErrorScriptline   = " & $oIEErrorHandler.scriptline & @CRLF
    $sError &= "-> ErrorNumberHex     = " & Hex($oIEErrorHandler.number, 8) & @CRLF
    $sError &= "-> ErrorNumber       = " & $oIEErrorHandler.number & @CRLF
    $sError &= "-> ErrorWinDescription = " & StringStripWS($oIEErrorHandler.WinDescription, 2) & @CRLF
    $sError &= "-> ErrorDescription = " & StringStripWS($oIEErrorHandler.description, 2) & @CRLF
    $sError &= "-> ErrorSource       = " & $oIEErrorHandler.Source & @CRLF
    $sError &= "-> ErrorHelpFile       = " & $oIEErrorHandler.HelpFile & @CRLF
    $sError &= "-> ErrorHelpContext = " & $oIEErrorHandler.HelpContext & @CRLF
    $sError &= "-> ErrorLastDllError   = " & $oIEErrorHandler.LastDllError & @CRLF
    ConsoleWriteError($sError & @CRLF) ; do what you want with the error message
EndFunc   ;==>_IEErrorHandler

Yu can use _IEErrorHandlerRegister() withou wriing your own error handler and it will put the messages into global variables for you. Please read the helpfile for _IEErrorHandlerRegister().

Thank You for the reply!

@Dale - How do i use these global variables? I read the help file but couldnt figure out how to use it. Can you please refer my sample script below and show me how to use it.

@RobJong - I tried using the custom error handler but i am not sure why it doesnt seem to work. I read the help file for _IEErrorHandlerRegister but couldnt get this working. Please see the sample code below. I have given a wrong name attribute value for password. I do get the default message from IE.au3 like below but the custom error handler ( _IEErrorHandler()) in the script below is not called and it doesnt show below error message. I need some way to control these messages so that i can write it to a log file.

Error Message --

"--> IE.au3 V2.4-0 Error from function _IEFormElementGetObjByName, $_IEStatus_InvalidObjectType

--> IE.au3 V2.4-0 Error from function _IEFormElementSetValue, $_IEStatus_InvalidDataType"

------

My Sample Script

#include <IE.au3>

_IEErrorHandlerRegister("_IEErrorHandler") ; register custom IE error handler

$oIE = _IEAttach("Dev Con - Internet Explorer", "Title")

$oDomain = _IEGetObjByName($oIE, "domain")

_IEFormElementSetValue($oDomain, "UNTOPR")

$oPwd = _IEGetObjByName($oIE, "password111") ; purposefully inserted a wrong name attribute value. So this line will throw error in the console.

_IEFormElementSetValue($oPwd, "TEst")

Func _IEErrorHandler()

ConsoleWriteError("I am in error handler function" & @CRLF)

Local $sError = "!> IE COM Error" & @CRLF

$sError &= "-> ErrorScriptline = " & $oIEErrorHandler.scriptline & @CRLF

$sError &= "-> ErrorNumberHex = " & Hex($oIEErrorHandler.number, 8) & @CRLF

$sError &= "-> ErrorNumber = " & $oIEErrorHandler.number & @CRLF

$sError &= "-> ErrorWinDescription = " & StringStripWS($oIEErrorHandler.WinDescription, 2) & @CRLF

$sError &= "-> ErrorDescription = " & StringStripWS($oIEErrorHandler.description, 2) & @CRLF

$sError &= "-> ErrorSource = " & $oIEErrorHandler.Source & @CRLF

$sError &= "-> ErrorHelpFile = " & $oIEErrorHandler.HelpFile & @CRLF

$sError &= "-> ErrorHelpContext = " & $oIEErrorHandler.HelpContext & @CRLF

$sError &= "-> ErrorLastDllError = " & $oIEErrorHandler.LastDllError & @CRLF

ConsoleWriteError("Error Message --> " & $sError & @CRLF) ; do what you want with the error message

EndFunc ;==>_IEErrorHandler

Long time no post where is docu on  _IEErrorHandlerRegister  even google seemed of little help

From https://www.autoitscript.com/autoit3/docs/script_breaking_changes.htm

Quote

_IEErrorHandlerRegister() has been removed. It's not required due to COM errors no longer being fatal.
