How pass autoit variant to a COM method

Hi ~ I have a OCX file and its IDL like below:

$Notify = ObjEvent($CZEMApi,"EMApiEvents_")

Func EMApiEvents_Notify($parameter,$reason)
   MsgBox(4096,"Notify", "Event catchall for " & $parameter & @TAB & $reason & @CR)
EndFunc

$CZEMApi.Caption = "for test"
MsgBox(4096,"caption",$CZEMApi.Caption)

Local $long = $CZEMApi.InitialiseRemoting()

Local $pVAR = ""
Local $result = $CZEMApi.Get("AP_MAG",Ptr($pVAR))

 

But issue is:

"G:\test.au3" (79) : ==> The requested action with this object has failed.:
Local $result = $CZEMApi.Get("AP_MAG",Ptr($pVAR))
Local $result = $CZEMApi^ ERROR

How to fixed this issue?

I try the VBScript code is ok,

Dim Api1
Set Api1 = CreateObject("CZ.EMApiCtrl.1")
call Api1.InitialiseRemoting()
call Api1.Get("AP_MAG",Value)
call WScript.Echo("Magnification = " + CStr(Value))

.. and what about this script?:

$Api1 = ObjCreate("CZ.EMApiCtrl.1")
$Api1.InitialiseRemoting()
$value=$Api1.Get("AP_MAG")
ConsoleWrite("Magnification = " & $value & @CRLF)

[id(1)] long Get(
                            BSTR lpszParam,
                            VARIANT* vValue);

  Get() Method has no [out,retval] attribute, I tried it get same failed.

And something obvious like this fails too?

Local $vVAR
Local $result = $CZEMApi.Get("AP_MAG", $vVAR)

 

Thanks for your reply, I tried it get same error.

"G:\test.au3" (66) : ==> The requested action with this object has failed.:
Local $result = $CZEMApi.Get("AP_MAG",$pVAR)
Local $result = $CZEMApi^ ERROR

You need COM error handler initialized to get more info about the error. ObjEvent is the function for this too.

Post the details you get. This should work.

 

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

; User's COM error function. Will be called if COM error occurs
Func _ErrFunc($oError)
    ; Do anything here.
    ConsoleWrite(@ScriptName & " (" & $oError.scriptline & ") : ==> COM Error intercepted !" & @CRLF & _
            @TAB & "err.number is: " & @TAB & @TAB & "0x" & Hex($oError.number) & @CRLF & _
            @TAB & "err.windescription:" & @TAB & $oError.windescription & @CRLF & _
            @TAB & "err.description is: " & @TAB & $oError.description & @CRLF & _
            @TAB & "err.source is: " & @TAB & @TAB & $oError.source & @CRLF & _
            @TAB & "err.helpfile is: " & @TAB & $oError.helpfile & @CRLF & _
            @TAB & "err.helpcontext is: " & @TAB & $oError.helpcontext & @CRLF & _
            @TAB & "err.lastdllerror is: " & @TAB & $oError.lastdllerror & @CRLF & _
            @TAB & "err.scriptline is: " & @TAB & $oError.scriptline & @CRLF & _
            @TAB & "err.retcode is: " & @TAB & "0x" & Hex($oError.retcode) & @CRLF & @CRLF)
EndFunc   ;==>_ErrFunc

Get COM error is:
 

test.au3 (82) : ==> COM Error intercepted !
    err.number is:         0x80020005
    err.windescription:    ÀàÐͲ»Æ¥Åä¡£

@trancexx I'm not sure .... but I think that I read somewhere that AutoIt not support for ByRef in ActiveX objects .
Am I right ?

Edit:  Second question:
Is it related to this user case ?

Try this:

Local $vVAR = Binary(0)
Local $result = $CZEMApi.Get("AP_MAG", $vVAR)
Local $vVAR = Binary("")
Local $result = $CZEMApi.Get("AP_MAG", $vVAR)

The code I wrote did support it. I don't know if something was changed afterwards.

However, I did leave small bug with initialization and intention to fix it during beta testing. Something that never happened. The bug was such that randomly execution would fail. But random isn't always.

The code I wrote did support it. I don't know if something was changed afterwards.

However, I did leave small bug with initialization and intention to fix it during beta testing. Something that never happened. The bug was such that randomly execution would fail. But random isn't always.

I tried all methods with parameter of VARIANT* ,float*, BSTR* also get same "Type mismatch"  error.
