Does AutoIt have a "RegisterTick" event method?

[ame1011]

Hi,

I'm just wondering if AutoIt has an event that is run at every line in the script that I can use to run custom code.

Thanks!

Explain what it is you're trying to accomplish, and maybe someone can actually figure out what you're trying to say. What you asked was if AutoIt can run some other code whenever it executes a line of code in the script if I'm getting what you said right. Frankly, that doesn't seem to make much sense as written.

I know PHP has a register_tick feature, which allows you to call a function for each CPU tick, but I can't figure why you'd want a script to do that. The closest I would think you could come is some AdLibRegister call that always returns True (and thus executes every 250ms).

We use a script that I created at work that runs overnight on several virtual machines.

The issue is that if the internet "flickers" or is temporarily disconnected in the middle of the script, the program crashes with an object error.

I have created a custom event handler for the IE automation library to combat this.

However, in order to check the error flag, I would have to add an "if" statement or a function after every object-related call to check or errors.

There are hundreds upon hundreds of object actions and adding a line of code after each one seems "clunky".

Consider the following code:

expandcollapse popup

Global $oIE = _IECreate("Google.com", 0, 1, 1, 1)
_IEErrorHandlerRegister("_IEErrorHandler")
$result = main()
if $result == "" Then
ConsoleWrite("success" & @CRLF)
Else
ConsoleWrite("failed at step: " & $result & @CRLF)
EndIf

func main()
if step1() == false then return "1"
if step2() == false then return "2"
if step3() == false then return "3"
if step4() == false then return "4"
if step5() == false then return "5"
if step6() == false then return "6"
if step7() == false then return "7"
if step8() == false then return "8"
if step9() == false then return "9"
if step10() == false then return "10"
return True
EndFunc
;example step
func step2()
;throughout this function there are error checks that return false if the step failed
;if step has not errors until the end, it succeeded and returns true
$oIE.document.action1
$oIE.document.action2
$oIE.document.action3
$oIE.document.action4
$oIE.document.action5
;...
$oIE.document.action100
return True
EndFunc
func _IEErrorHandler()
; do something on oIE errors
EndFunc

Let's say there is a COM object error for IE on line 35 ("$oIE.document.action3").

How do I make the script return false on step2() immediately without putting an if statement after each one of those 100 actions (note that each action can have a COM object failure).

[JohnOne]

If it were me, I'd probably put code in my error handler function to ensure that the internet is connected

and $oIE is an object, however your function still would not return false immediately but you could set a

global error flag and return false at the end of the function.

You might think if statements are clunky, but if you want a robust script you should consider them.

Consider using == only for case sensitive string comparision. Also, your comment for step2() says that a false is returned upon error but I'm not seeing it. Consider returning something else other than True on sucess because 1 and true are the same.

Here is some more accurate based on what you gave us.

expandcollapse popup

#include <IE.au3>

Global $oIE = _IECreate("Google.com", 0, 1, 1, 1)

If @error Then Exit -2

_IEErrorHandlerRegister("_IEErrorHandler")

Global $result = main()

If $result = True Then
    ConsoleWrite("success" & @CRLF)
Else
    ConsoleWrite("failed at step: " & $result & @CRLF)
EndIf

Func main()
    If Not step1() Then Return 1
    If Not step2() Then Return 2
    If Not step3() Then Return 3
    If Not step4() Then Return 4
    If Not step5() Then Return 5
    If Not step6() Then Return 6
    If Not step7() Then Return 7
    If Not step8() Then Return 8
    If Not step9() Then Return 9
    If Not step10() Then Return 10
    Return True
EndFunc   ;==>main

;example step
Func step2()
    ;throughout this function there are error checks that return false if the step failed
    ;if step has not errors until the end, it succeeded and returns true
    $oIE.document.action1
    $oIE.document.action2
    $oIE.document.action3
    $oIE.document.action4
    $oIE.document.action5
    ;...
    $oIE.document.action100
    Return True
EndFunc   ;==>step2

Func _IEErrorHandler()
    ; do something on oIE errors
EndFunc   ;==>_IEErrorHandler

Or perhaps

If Not step1() Then Return SetError(1,1,0)

If Not step2() Then Return SetError(1,2,0)

If Not step3() Then Return SetError(1,3,0)

etc...

Return 1

Take a look at the code in by Water that shows a custom error handler for object errors and how they can be handled safely.
