Error handlers are important to have especially when you're writing and developing some type of project. If you write the program correctly they shouldn't go off unless something fails which means you have some problem with your code.

If @error = 1 Then MsgBox(0, 'blah', 'error')

Here's an example when I didn't use them but when jos recommended them they came in handy.

If you intend to create reliable scripts you should NEVER ignore ANY error.
Catch them, analyze them and then act accordingly. But NEVER ignore anything whithout knowing what you ignore.

If you can post some code and explain where your errors occur we might give further advice.

Actually it's not about syntax errors. My program is complicated and it contains loops that depend on some softwares reactions. What I need is to make my program ignore any error occurred and move to the next step and continue working.

 

Func _Example_CatchErrors()
    While 1
        _Function1()
        If @error Then ContinueLoop
        While 1
            _Function2()
            If @error Then ContinueLoop
            ExitLoop
        Wend
    Wend
EndFunc

Func _Example_IngoreErrors()
    While 1
        _Function1()
        If @error Then ExitLoop
        While 1
            _Function2()
            If @error Then ExitLoop
        Wend
    Wend
EndFunc

 

btw.
How complicated it is ?

check it using:
 

#Au3Stripper_Parameters=/RM /SO /RSLN /PE

And check ***_stripped.au3 file how many lines and bytes it contains

 

For example:   my biggest project have :       35516 lines and 1 251 423 Bytes

      Hi Folks
      Can not get my head around this one.
      This function gets the DNS object s
      If you have two DNS entries fine. but if you have only one! Trouble
      $objItem.DNSServerSearchOrder[0] = Primary DNS
      $objItem.DNSServerSearchOrder[1] = Secondry DNS not always there. I need a way to return 0 if not there or the IP if its there.
      Or is there a way to tell how many objects there are in the "[?]"
      I'm terrible at WMI errors, thanks for help in advance.
      Func _GETcurrentNICinfo2() $oErrors = ObjEvent("AutoIt.Error", "Error_Handle") Local $DnsSecondry Local $objWMIService = ObjGet( "winmgmts:\\" & @ComputerName & "\root\CIMV2" ) Local $query = $objWMIService.ExecQuery("SELECT DNSServerSearchOrder FROM Win32_NetworkAdapterConfiguration WHERE Index = " & _GetSelectedNIC(), "WQL", 0x30 ) If @error Then Return 0 If NOT IsObj($query) Then Return 0 Else For $objItem In $query Return $objItem.DNSServerSearchOrder[1] next Endif EndFunc

      Hey, guys.
      Currently, I'm using Opencv UDF and i'm  encountering issues with DLLOPEN(). it is failing and returning -1
      But, I cannot figure out why it is failing.
      I need help from people.
      I'm running windows 10 32bit.
      This's my code.
      #RequireAdmin $fileopen = DllOpen("opencv_core2413.dll") MsgBox(0,"Result",$fileopen) Example.au3opencv_core2413.dll

      This script used to work on an older version of AutoIT. Currently I am running AutoIT v3.3.14.5 and it's failing.
      Func PublicIP() ;Post public facing IP address Local $url = 'https://www.google.com/search?client=opera&q=what+is+my+ip&sourceid=opera&ie=UTF-8&oe=UTF-8' Local $getIPaddress = BinaryToString(InetRead($url)) Local $sStart = 'clamp:2">' Local $sEnd = '</div>' Local $ipaddress = _StringBetween($getIPaddress, $sStart, $sEnd For $i In $ipaddress MsgBox(0, 'External IP', "Your public IP address is " & $i) Next EndFunc ;==>PublicIP The console output shows:

      I'm listing the error message strings, and roughly matching the error code
      Is this how to do error reporting?  Is there a more simple way I don't know about?
      I realise I might not need to trap @error inside $error.  I like it this way b/c I have no fear of overwriting @error now; I don't even use it.
      Func Send_Connect($address, $port)     $socket = TCPConnect($address, $port)     $error = @error     If $error <> 0 Then         Local $aError[4] = ["-2 not connected.", _                             "1 IPAddr is incorrect.", _                             "2 port is incorrect."]         $aError[3] = "10060 Connection timed out."         If $error < 0 Then $error = 0         If $error > 2 Then $error = 3         MsgBox(0, "TCP Connect Error", $aError[$error], 0)         $socket = 0     EndIf     Return $socket EndFunc
