Hi,
I can now add projects, assign users, etc...
I am now investigating the database side of this project. It seems the data is being save in sql server .mdf file
There is now a TimeTracker.mdf in the data folder of sql server but I can NOT create this database in the object explorer using attach database.

When doing this in sql 2005 by right click, new database; this is the error I get:
create database failed. some file names listed could not be created. Check related errors. Can not create file 'c:\program files\...\TimeTracker.mdf' because it already exists. change the filepath or the file name, and retry the operation.
Note that there is a .mdf file in the above path already and I would

like to use that as the database.
So I try to attached this .mdf file, and I get this error when attaching it:
create file encouontered operating system error 32(error not found) while attempting to open the physical file 'c:\program files\TimeTracker.mdf' (Error 5123)

Any suggestions please?

 You need to attach the database in SQL Server Management Studio and not create it.

Time Tracker use the TimeTracker.mdf' under SQL Server Express,

So you have to attach to Sql server Management studio.

The system does not allow me to attached.

 Is this a local server?

Yes it is.

Check to make sure that the sqlservr.exe user has read and write access to the MDF file.  You can see who the user is with Task Manager.

It shows Administrator who is me logged in to the machine.

Try to install VS 2005 SP1 and other other related updates

May solve this one

1    EXEC sp_attach_db @dbname = 'PUBS', 
2    
3         @filename1 = '\Program Files\Microsoft SQL Server\MSSQL\Data\PUBS.mdf', 
4         @filename2 = '\Program Files\Microsoft SQL Server\MSSQL\Data\PUBS_LOG.ldf'
5    
6    sp_detach_db [ @dbname = ] 'dbname' 
7                 [ , [ @skipchecks = ] 'skipchecks' ] 
8    

When you have the web site open in Visual Studio you can use the Database Explorer to examine the database. You should find it on the View menu of VS.

What is the status, Please update

Have solved your error

if you start the vs,it may be use the database.you should to release it!

Any updates on this
