Hi all,

I have the computer programs of VWD Express, SQL Server Express and SQL Server Management Studio Express installed in my Windows XP Pro PC that is on our Microsoft Windows NT 4 LAN System. I started my first VWD Express-Visual Basic database application by creating a new Web Site (named "Presidents") and I followed a VWD Express book's instructions to create App_Data (VWDB.mdf and VWDB_log.LDF),  MasterPage.master, AddItem.aspx, Book.aspx, Default.aspx and web.config. There is a Master-Detail relationship in Book.aspx.  This "Presidents" project did not work when I executed it.  I tried to erase this project completely from my PC by deleting the Presidents.sln file. But it seems to me that some files/source codes of my "Presidents" project are still in my VWD Express program, because a new Presidents.sln (I downloaded from the website of the book publisher and saved it in the same folder of "Presidents" in my C:/ drive) did not work when I clicked it.   I am stuck in this crack.  Please help and tell me:

1)  How to delete/eliminate the old source code, files, folders and Presidents.sln completely from the VWD Express program in my PC.

2)  How to execute the book publisher's new source code, files, folders and Presidents.sln in my PC.

Please give me your delailed instructions to solve my problem and get the book publisher's new VWD souce code, files, folders, etc. installed and executed in my PC.

Thanks in advance,

Scott Chang   

Update my post:

My Computer Administrator granted me the Administrator Privilege on my Windows XP Pro PC that is on Microsoft Windows NT 4 LAN System. I have no URS in my PC and I just use my local host of Internet to do/learn the VWD Express applications.

This morning, I entered my C:\Documents and Settings\e1enxshc\My Documents\Visual Studio 2005\Projects\Presidents and deleted all the folder (App_Data), files (Book.aspx, Default.aspx,  MasterPage.master), Presidents.sln and web.config (I created before) and copied the book publisher's  (App_Data), files (Book.aspx, Default.aspx,  MasterPage.master), Presidents.sln and web.config to this C:\Documents and Settings\e1enxshc\My Documents\Visual Studio 2005\Projects\Presidents.  Then I started my VWD Express program and opened the Presidents project => I did "Build" and "Execute" the Book.aspx via the local host and I got the the following error:

Server Error in '/Presidents' Application.
