Error Handling in AutoIt

[the123punch]

Hello everyone,

I am getting better and better at AutoIt but I am still at the newbie level lets say so I have to ask the following question:

I am trying to implement some sort of error handling in my autoit script. I have seen on this forum that some people do it in that way:

Declaring the error object:

Global $oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

Having the error handling function:

; Com Error Handler

Func MyErrFunc()

$HexNumber = Hex($oMyError.Number, 8)

$strMSG = "Error Number: " & $HexNumber & @CRLF

$strMsg &= "WinDescription: " & $oMyError.WinDescription & @CRLF

$strMsg &= "Script Line: " & $oMyError.ScriptLine & @CRLF

MsgBox(0, "ERROR", $strMSG)

SetError(1)

Endfunc

So if I am not mistaken, this should pop a message box with the error information if an error happens during my script.

The reason I need this is that I have some SQL statements in my code that will insert new rows into a db table and for some reason it is not inserting, so I am assuming some sort of error could be happening.

After adding the above code, when I compile, and I try to run, my AutoIt application does not run and I get the following error when I run the resulting .exe:

Line -1:

Error: Variable must be of type "Object".

What am I missing? What am I doing wrong? Can anyone help?

Thanks.

Why not run the source au3 file and find out what line the error occurs at. Perhaps you are making a different kind of mistake.

Try this, it worked for me.

Global $oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

;----------------------------------------------------------------------------------------------------------

; Com Error Handler

;----------------------------------------------------------------------------------------------------------

Func MyErrFunc()

Local $HexNumber

Local $strMsg

$HexNumber = Hex($oMyError.Number, 8)

$strMsg = "Error Number: " & $HexNumber & @CRLF

$strMsg &= "WinDescription: " & $oMyError.WinDescription & @CRLF

$strMsg &= "Script Line: " & $oMyError.ScriptLine & @CRLF

MsgBox(0, "ERROR", $strMsg)

SetError(1)

Endfunc

newbie here. Why do you need to setError to 1?

Can't catch this error:

---------------------------

AutoIt Error

---------------------------

Line 17 (File "D:__MyLocalWorkAutoIT3_ScriptsDetectProcess.au3"):

$objProcess.GetOwner($user)

$objProcess.GetOwner($user)^ ERROR

Error: The requested action with this object has failed.

---------------------------

OK

---------------------------

Try this, it worked for me.

Global $oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

;----------------------------------------------------------------------------------------------------------

; Com Error Handler

;----------------------------------------------------------------------------------------------------------

Func MyErrFunc()

Local $HexNumber

Local $strMsg

$HexNumber = Hex($oMyError.Number, 8)

$strMsg = "Error Number: " & $HexNumber & @CRLF

$strMsg &= "WinDescription: " & $oMyError.WinDescription & @CRLF

$strMsg &= "Script Line: " & $oMyError.ScriptLine & @CRLF

MsgBox(0, "ERROR", $strMsg)

SetError(1)

Endfunc

Make sure that the line

Global $oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

is at the top of your script.

Another change is needed:

Func MyErrFunc()

should be

Func MyErrFunc($oMyError)

[erm3nda]

Does this capture an error like: msbox(blah) ?? (bad syntax)

I need the simplest way to detect any error and retry the func again or retry whole app if needed.

Is this your thing? Complaining that something doesn't work across the Forum without actually showing us what isn't working.

Yes it is. Im reading this post to know how to catch some errors. Just searching for something like try/catch.

I cannot tell you what is failing because i don't know, and a lot of sensitive info is involved, so i cannot put here the full source.

When i can made a example script reproducing the error you will know.

I Apologize.

Can you point me to the correct way (documentation) to handle with errors? Regards.
