Add / Remove the default documents of IIS7 using vb.net 2.0 windows application

Question

Hai,

I wrote the coding for add / remove the default documents of IIS7 in vb.net 2.0 windows application using Microsoft.Web.Administration.dll. The coding is working fine. After adding a new document, the messagebox showing that newly added document name. Simillarly if I remove any document, the messagebox not showing that document name. So that I am saying, the coding is working fine.

Now the problem is, I can't see the newly added document name in II7 Manager GUI. The next proplem is, my website not access that newly added document.

Please can any body suggest for these problems. What the mistake I did the vb.net 2.0 windows application coding and what are the modifications I need to do?

Thanks in advance.
