using winax in nw.js with web worker

[danielemarsico]

Hi,

I'm trying to user winax in a project with nw.js using WebWorker. I can load the module inside a webworker using

activex = require('node-activex');

and i works fine. But if another web worker wants to use the samemodule I get error: Module didnot self register.

My question is this module can be used ia multithreading application (like using webworker?) if so is there any setup to be done in advance?

Thank you! I love this project!

Theoretically, multithreading is supported, but web workers can't require node modules and I do not find the opportunity to transfer winax it into the worker

You will have to use same Worker instantiated globally. Send different messages to execute different tasks on the worker. I have done it this way.

Thank you for the feedback, I’m doing the same way, just trying to figure out how to centralize the management of the calls.

Well I am fairly a newby when it comes to JavaScript.

But what I am doing is like following:

In both the Main thread AND in the worker thread I declare an enum like this: const operation = Object.freeze({ 'connect': 0, 'disconnect': 1, 'get_sdk_version': 2, 'another-function': 3, 'etc: 4 })

In the main (calling) I call any function on the Worker with JSON object containing a operation value and any args I may have, such as: worker.postMessage({ 'operation': operation.connect, 'whatever_arg': 'my argument' })

In the worker thread: `onmessage = function (e) {

var opp = e.data.operation

switch (opp) {

    case operation.connect:

        var file_path = e.data.whatever_arg

        // do function and return postMessage when completed with result inside a JSON

       break

    case operation.disconnect:

      do_disconnect();

      break

    case etc

    end so forth...

`

Got the same issue using worker threads. The first time the thread requires the module it works fine and ActiveX object are loaded correctly. Second thread gets

Error: Module did not self-register. at Object.Module._extensions..node (internal/modules/cjs/loader.js:805:18) at Module.load (internal/modules/cjs/loader.js:653:32) at tryModuleLoad (internal/modules/cjs/loader.js:593:12) at Function.Module._load (internal/modules/cjs/loader.js:585:3) at Module.require (internal/modules/cjs/loader.js:690:17) at require (internal/modules/cjs/helpers.js:25:18) at Object.

Is there any way to use activeX objects with threads ? I could not find a way to require it only once and pass the instance to the worker.

Hi Durs Thanks for the fantastic effort in developing this utility Any news on making it thread compatible ?

After a gap of almost two years back, I tried it with latest Node. winax is now working smoothly with worker_threads module of node js
