WebBrowser multi-threaded RRS feed

  • Question

  • Hi,

    I have a main form that will be a control center which has a list where element will have
    a button to launch a process with "BackgroundWorker" an application that have a "WebBrowser" inside.

    I'm getting "Unable to get the window handle for the 'WebBrowser' control. Windowless ActiveX controls are not supported."

    That was working fine before adding the "BackgroundWorker".

    My understanding is the "WebBrowser" must be running on the main thread?

    I want a "WebBrowser" object on different thread for crawling multiple sites.

  • What are you doing once you crawl to the site?
    I need a job!

  • If you are performing crawling and no rendering to the UI, i would recommend the use of WebClient instead.

  • Thanks for the information.

    That class is to simple. I might encounter JAVA site, need to simulate click (add to basket, next page, etc).

    Anyone has a solution to my problem?

    The only thing I can see is to have each of my class as an executable.
    But the problem will be how to communicate back to my "Control Center"?
    I want my "Control Center" to receive status (progress bar & Message) and
    to be able to Start/Cancel the crawl.
