c# - Opening a Hidden Internet Explorer Window without it getting Focus?

Question

I want to open a hidden Internet Explorer window without it stealing focus. I have a Timer object that opens Internet Explorer every 5 minutes to check a website for updates. The problem is every time it checks for updates, it steals focus from the current application in the foreground. Below is how I start the process:

        Process m_Proc = new Process();
        m_Proc.StartInfo.Arguments = String.Format("{0}{1}", "-nomerge ", browserURL);
        m_Proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        m_Proc.StartInfo.UseShellExecute = true;
        m_Proc.StartInfo.CreateNoWindow = true;
        m_Proc.StartInfo.FileName = String.Format("iexplore.exe");
        m_Proc.Start();

It always steals focus, even when it is hidden. I want it to start like nothing is happening, so users can continue to work on what they are doing. Thanks.

Try automating Internet Explorer via its COM interfaces rather than creating a process explicitly. Here's how it can be done. Just don't do ie.Visible = true and it will stay hidden. Call ie.Quit() when done with it.
