Webbrowser Control Limitations

Question

I am using the WebBrowser control in a windows form C# project and wanted to know if there are any limitations of how many instances of such application you can have running at the same time. (in other words does MSFT enforce any limitations other than physical machine limits - CPU/memory etc)

Answer 1

Try out this code and see what happens:

int count = 0;
List<Form> forms = new List<Form>();
try
{
    while (true)
    {
        Form f = new Form();
        WebBrowser wb = new WebBrowser();
        f.Controls.Add(wb);
        f.Show();
        wb.Url = new Uri(@"http://www.stackoverflow.com");
        forms.Add(f);
        count++;
    }
}
catch
{
    MessageBox.Show(count.ToString());
}

I'm going to guess it's hundreds, but I dunno.

Answer 2

There are no artificial limitations on the WebBrowser control.

However, it uses IE's rendering engine (whatever version is installed on the end-user's computer), so it uses a fair bit of memory.

What are you trying to do?

If you're trying to write a web browser, I recommend that you use a better rendering engine, such as WebKit or Gecko.
