1658	COM / OLE object access causes error code 80020003 - member not found	Frank <temp.kfl42ai@…>	Jon	"Hallo,

while writing some AutoIt scripts to automate one of our ERP-Applications, which includes an OLE / COM Interface with late bindung, I get some exceptional errors.

For some methods of the COM-Objects, the following error was reported: COM-Object error 80020003, Member not Found.

The same methods or rather the whole COM Interface works fine when using it with other programming languages like VBA, VBScript, C# VC++ etc. in the same environment (OS etc.) and the same manner (syntax etc.).

Therefor the software vendor says that his application (written in Delphi) and its COM-Interface (Type: late bindung) is in proper style and it must be an problem with AutoIt.

Here is an example:



{{{
Local $oHWP
Local $wert
Local $i

$oHWP = ObjCreate (""HWP.Anwendung"")

if ($oHWP.Angemeldet = 0) Then         ; check if logged in -> works
    $oHWP.Anmelden (""USER"",""PASSWORD"") ; login with credentials ->
                                       ; cause COM-Error 80020003 - 
                                       ; Member not found
endif

$wert = $oHWP.Version                  ; get version number -> works

$wert = $oHWP.Table(""ADR"").Anzahl      ; number of contacts -> works

$oHWP.Table(""ADR"").ErsterSatz          ; go to first record ->
                                       ; cause COM-Error 80020003 -
                                       ; Member not found""

For $i = 1 to $wert
    ; do something with current record,
    $oHWP.Table(""ADR"").NaechsterSatz   ; go to next record -> works
Next

$oHWP = 0

Exit
}}}


It's very strange that the statement ""$oHWP.Table(""ADR"").NaechsterSatz"" works fine while the statement ""$oHWP.Table(""ADR"").ErsterSatz"" causes an error although both works fine while using them in many other programming languages.
Also an simple call of the method ""$oHWP.Anmelden (""..."")"" causes an error 80020003 while it doesn't in VBA etc.

Is there a bug in AutoIt?

P.S.:
- All error codes are determined by standard error handling of AutoIt ($oMyError = ObjEvent(""AutoIt.Error"",""MyErrFunc"") etc.), which was omit for the reason of clarity of code.
- Using of COM methods (syntax etc.) in the example above is in accordance of the programming guidelines of the software vendor
