Using DLL functions, objects

[vgt1]

I'm trying to get AutoIt to use functions contained in a DLL file. The author of the DLL file gives examples on how to use it, but only in Python or Labview. I know basically nothing about object-oriented programming, so I don't know if AutoIt can even do this.

 

The instructions say that a "XXS" object must be created, an "XXFct" object created, and the "XXS" object connected to the FCT api. Here's the Python example provided:

 

from xxSerial import XXS
from xxSerial import XXFct

myXXS = XXS("COM9")
fct = XXFct()

fct.connect(myXXS)

 

I tried acting like an AutoIt variable could be an object as in the Python example. There's a function called XXFct.getVersion() that is supposed to return something. I didn't get any errors, but I just get a 0 in my message box where there should be a number or string (I don't actually know what the returned version is supposed to look like, but I'm sure it's something other than 0). Here's what I wrote:

 

Local $hDLL = DllOpen("xxFct.dll")

local $myXXS = DllCall($hDLL,"STR","XXS","STR","COM9")
local $fct = DllCall($hDLL,"STR","XXFct")
DllCall($fct,"none","connect","HANDLE","myXXS")

local $vers = DllCall($hDLL,"STR","getVersion")

MsgBox(0,"",$vers)

DllClose($hDLL)

 

Any ideas if I can use AutoIt this way?

Hello. could you provide the dll doc?

Check how dll call works. It return an Array.

Oh, I didn't notice that, thanks. Also, I suppose I should have checked the error flag before making this post, because now that I've done so, I see that it'S returning "function not found" errors.

 

So my next question is: do I have to do something special to access a function that seems to be contained in a 'folder'? That's how I'm thinking of it at least, like a file tree. Peeking in the DLL file (fct.dll) with a decompiler, it's kind of like this: fct/xxSerial/XXFct/getVersion(). So in the Python example, I guess it's saying "import XXFct which is inside of xxSerial".

 

I don't think I can provide the DLL file. It's a part of a proprietary test for our customer's product, and I don't know what might be gleaned from it that I shouldn't make public.

You need to learn more about Python import system.

I'm not asking for the DLL file. I'm asking for the DLL documentation C/C++ header declaration or so.

I can't stay helping you too much without that information.
