Question

Hi,

I have a web browser control that access a webpage on the web, this is no problem for most users, but I have one user have in problems. This user is prompted for proxy username and password when they are surfing the web through IE.

My problem is that the webbrowser control does not throw up this login box. The user gets a page cannot be displayed error

Any advice on how to present this login box to the user?

Thanks,
