In 5.2 version, I see you can write such code in index.html:

```
  Visualizer.connect({
           application: 'visualizer',
           dataFile: 'a.vtk',
           dataDir: ""
       });

```

And in this way - to pass a file name from the html to python.  
Can I do this in 5.6 v?  
Which arguments `connect` function expect to get?

I do not know if it matters, but I am using in cmd to run visualizer by:

> .\bin\pvpython.exe share\paraview-5.6\web\visualizer\server\pvw-visualizer.py --content share\paraview-5.6\web\visualizer\www\ –data “data” --port 8080

Thanks.

The configuration provided in the connect is used by the launcher when starting the application for you dynamically so extra arguments can be provided such as `which file should be loaded at startup`.

In your case, since you start Visualizer by hand first. That configuration object is useless and will have no affect.

Thanks for your answer.  
Now I run Apache httpd.exe, and follow these insructions:

> **[ParaViewWeb](https://kitware.github.io/paraviewweb/docs/windows_10.html)**
>
> ParaViewWeb on WindowsThis readme described the process of setting up a Paraview Web Server instance on a Windows 10 workstation. Once the ParaView Web is setup, the Visualizer app may be embedded in

And it run, but it does not respond to the data I send from html, like in the question.  
Any help?

By the way, I work with version 5.6, and my launcher.bat file seem so:

> set PV\_HOME=C:\ParaView-5.6.0  
> PV\_HOME\bin\pvpython.exe PV\_HOME\bin\Lib\site-packages\wslink\launcher.py PV\_HOME\launcher.config

What is the content of your `launcher.config`?

You can create custom command that will then use your arguments provided in the config object to properly form the command line you intend to.
