Catch error in Object COM

6 posts in this topic

#1 ·  Posted (edited)

Hello,

I try to catch error in this code:

$AmiBroker = ObjCreate("Broker.Application");
$ChkTicker = "ABC"
$bb=$AmiBroker.Stocks($ChkTicker).Ticker

If in program Broker "ABC" exist than all is alright, but if "ABC" not exist I get error.

I translate code from Windows Stript Host, but this problem resolved by "TRY, CATCH"

AmiBroker = new ActiveXObject( "Broker.Application" );
ChkTicker = "ABC";
function Main()
{
    if( AmiBroker.Stocks.Count > 0 )
    {
        try
        {
            return AmiBroker.Stocks( ChkTicker ).Ticker == ChkTicker;
        }
        catch( e )
        {
            WScript.echo("error");
        }   
    }
    return false;       
}   
Main();

How I do this in Autoit?

THX

@JohnOne, like this?

Global $oError = ObjEvent("AutoIt.Error", "_ErrFunc")
Func _ErrFunc()
;~  ConsoleWrite("! COM Error !  Number: 0x" & Hex($oError.number, 8) & "   ScriptLine: " & $oError.scriptline & " - " & $oError.windescription & @CRLF)
EndFunc   ;==>_ErrFunc

Global $AmiBroker = ObjCreate("Not.Broker.Application");
If $oError.number Then
    MsgBox(48, "Error", "Error number = " & Hex($oError.number, 8))
Else
    ; Maybe
EndIf

;...

If...Then...ElseIf...Then...Else

maybe.

I try use ObjEvent and @error, but it's not work.

My code returns:

==> Object referenced outside a "With" statement.:

$bb=$AmiBroker.Stocks($ChkTicker).Ticker

$bb=$AmiBroker.Stocks($ChkTicker)^ ERROR

,when result "ABC" is not on database at broker application.

I only wont to chect it, and javascript allows to chect it by Try/Catch.

BTW if in javascript I use etc. If AmiBroker.Stocks(ChkTicker).Ticker=="ABC" it returns similar error.

You don't know what javascript allows. You don't have that capability.

Learn basics (like 1+1=2) and then ask what you want.

...Only then you won't since you'll be seeing that your question is already answered.

ok :graduated: but I have it!, look:

Global $g_eventerror = 0  ; to be checked to know if com error occurs. Must be reset after handling.

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc") ; Install a custom error handler

; Performing a deliberate failure here (object does not exist)
$oIE = ObjCreate("Broker.Application")
 $oStocks = $oIE.Stocks("ABC");
 $oSymbol = $oStocks.ticker;
if $g_eventerror then Msgbox(0,"","the previous line got an error.")

Exit


; This is my custom error handler
Func MyErrFunc()
   $HexNumber=hex($oMyError.number,8)
   Msgbox(0,"","We intercepted a COM Error !" & @CRLF & _
                "Number is: " & $HexNumber & @CRLF & _
                "Windescription is: " & $oMyError.windescription )

   $g_eventerror = 1 ; something to check for when this function returns
Endfunc

This code returns COM error info when "ABC" is not on "the list".

Thx to all
