Autoit not seeing [out] parameters

[tlman12]

so I'm trying to interface with a programs API and everything seems to work fine with autoit. i can create the object, initialize it, run the functions.

the problem comes when the function has an [out] parameter.

so like there's a function that is .GetLastError($errortext) but $errortext is an output and the function is supposed to write the results to that variable. instead of getting error text i get nothing.

the functions accept inputs just fine, and it works properly in vbscript. i'd like to use autoit though so i can create a gui wrapper for the api calls.

is there something i should be doing to get the info from the variables? or is there a special way to declare the variables? i've never had this problem before.

[water]

Can you please give us more information?

Which program's API do you use?

What have you coded so far?

[tlman12]

sorry for the lack of info before, i was hopeing maybe i was doing something stupid and someone would key on on what it was.

it's for Sophos SafeGuard encryption

http://www.sophos.com/en-us/medialibrary/PDFs/documentation/sgn_60_m_eng_api.pdf

and basically all i did was convert this VBscript to AutoIT.

like i said most of it works, just nothing where the parameter is an [out]

like this one ComputeResponse(string adsUser, string adsMachine, string challenge, int action, out string response)

the return funcions properly returning a good error code from the table in the document so i know the function is working properly but the outs are more important

To help you with your AutoIt code we need to see your AutoIt code ...

the autoit code is practically verbatim of the vbs code so i'm not sure how it's going to help, but imho this script is worthless to anyone trying to help me that doesn't have sophos safeguard encryption unless you know what the problem may be. it doesn't get past line 38 without the software installed. and on my computer everything works but the [out] variables in the functions.

... so like there's a function that is .GetLastError($errortext) but $errortext is an output and the function is supposed to write the results to that variable. instead of getting error text i get nothing. ...

Shouldn't the line

$ret = $Scripting.GetLastError($ErrorText)

then read sonmething like:

$ErrorText = $Scripting.GetLastError()

What is supposed to be in variable $ret?

[trancexx]

^^ tlman12 said the parameter is [out], he didn't say [retval]. That's big difference.

Unfortunately he failed to give more info about the version of AutoIt he's using, so my best guess is that he's using some buggy version. I would recommend trying newer.

$ret is set to the success/fail number value from my list above, so 0 means the function ran properly 1 means it failed. The API reference that i posted a link to has this as the description of that function

Uint32 Base::GetLastError(out string errorText)

Retrieves a textual representation of the last (internal) error occurred.

Note: In contrast to other API methods this method returns an unsigned integer which holds the

internal error code.

i'm using the most current version 3.3.8.1

[water]

Could you please set variable $ErrorText to a value (e.g. "**") before GetLastError is called? So we can see if the function touches the variable at all.

[trancexx]

i'm using the most current version 3.3.8.1

Try newer. Edited April 16, 2013 by trancexx

[tlman12]

Try newer.

beta? cause 3.3.8.1 is the current version

[water]

On this page you'll find the link to the download section. Try 3.3.9.4

didn't work with beta either. is there any reason this wouldn't be working? i would think that if it works in vbscript it should work in autoit. and like i said, based on the actual return values, i know the functions are working properly. i'm just not getting the info i need.

[water]

... based on the actual return values, i know the functions are working properly.

If the function works properly why do you think GetLastError should return a value?

Have you tried my last suggestion?

it's not just GetLastError. i only used that as an easy example

like i said most of it works, just nothing where the parameter is an [out]

like this one ComputeResponse(string adsUser, string adsMachine, string challenge, int action, out string response)

the return funcions properly returning a good error code from the table in the document so i know the function is working properly but the outs are more important

it is any function that returns its data with a byref or an [out] variable but based on the return values it is accepting the byval or [in] variables

also $ErrorText in the GetLastError us supposed to return "OK" on a good return.

There are several reasons for your code not to work correctly. What you should do to determine the cause of failure is to run this code:

$Scripting = ObjCreate("Utimaco.SafeGuard.AdministrationConsole.Scripting.Base")

ConsoleWrite(@AutoItVersion & @CRLF)
ConsoleWrite(VarGetType($Scripting) & @CRLF)
ConsoleWrite(ObjName($Scripting, 4) & @CRLF)

...and then after you confirm correct version of AutoIt and object generation you should load with the file whose path will be printed as third line of the console output and then search for the method of the object that doesn't work like you expect it. When found, post the method definition here.

Ran that, didn't get a file path so i added the rest of the numbers in that objName() and got that console print.

How do you know it's [out]? Is there any documentation?

...I'm co-author of that part of AutoIt so I know what conditions need to be met to get the behavior you expect.
