addEventListener() is a JavaScript method, and the old Microsoft WebBrowser Control does not support modern HTML pages (with current JavaScript stuff).\n\nWe would recommend you to upgrade OR6.2 to OpenROAD 11.2 that comes with WebView2 support - see according documentation:\n\nhttps://testdocs.actian.com/openroad/11.2/index.html#page/RelSum/WebView2_Updates.htm \n\nhttps://testdocs.actian.com/openroad/11.2/index.html#page/LangRef/Url_Method.\n\n \n\nAlternatively, you can use the CALL SYSTEM statement to open the web site externally (in a separate web browser window like Edge, Firefox or Chrome).
