Invoke TestComplete from a Web Page developed on .NET

I am trying to invoke TestComplete from a  web page developed on .NET 4.5 and HTML5. I am using the code given in the following path https://support.smartbear.com/viewarticle/75758/.

I am able to successfully invoke TestComplete, but it lands into error as the following command fails  Application.DoEvents();

The particular command is used for Windows Forms and not for Web application. Could some one advise what is the equivalent method or process to replace  Application.DoEvents() in Web application.

Thanks
