Disable the "Internet explorer is not currently your default browser" warning when using IWebBrowser2

I have a MFC application that launches a IWebBrowser2 win开发者_Python百科dow. On users computers where Internet Explorer is not their default browser they get the following warning message

"Internet explorer is not currently your default browser. 
 Would you like to make it your default browser?"

Is there a way to disable this check before I launch a IWebBrowser2 window?

Are you using CHtmlView/CHtmlEditView? We do and don't get that message if IE isn't the default browser.
