Cannot open web project

[M]

I download a web sample project and put it in D:VbWebSample1
I create a new virtual directory alias as VbWebSample1 with IIS and
the directory point to 'D:VbWebSample1 '

I can see all the files in IIS under 'Default Web Site/VbWebSample'
I run the check server extensions from IIS

but I cannot open the project.
If I open with 'Open Project with Web..'
the open Project from Web dialog show up and I type in
http://localhost/VbWebSample1/WebSample.vbp and click OK
Then Open Project dialog show up, It is empty under the VbWebSample1
I cannot see any file under VbWebSample1 from open project dialog.

How to solve the problem

Thanks
