Having Problem with SQL Express 2005

I just started working with sql server 2005 and i have a windows-based application in C# with an attached sql server database file.Everything is ok but i don't know if i can create a password for that database.
there is no IDE for sql server 2005 like Enterprise Manager in SQL Server 2000 to do such things(Creating roles,passwords,...).In my computer I've installed VS 2005 Professional and SQL Express.I think i should do all thease thing with system stored procdures right? But it's really boring do all those things without an IDE.

Thanks in advance.

If you have a look at the following link you will find a download for SQL Server Management Studio Express, this is an IDE based of the full management studio (Replacement for Enterprise manager and Query tools) that can be used for the express editions.
