How to use the downloadable

applications for Murachs

ASP.NET 2.0 Web Prog ramm ingw ith C# 2005

Thank you for downloading the sample applications forMurachs ASP.NET 2.0 Web

Programming with C# 2005. If you have installed Visual Studio 2005 on your system,

and you have successfully unzipped the downloadable files, you are ready to begin

working with many of these applications. However, before you begin working with the

sample applications that use the Halloween database, you must attach this database toSQL Server Express. In addition, you must grant ASP.NET the proper access to this

database. Youll learn how to perform these tasks in this document.

How to attach the database and grant ASP.NET

access to it from Windows Explorer

The easiest way to attach the Halloween database to SQL Server Express and grant

ASP.NET access to it is to run the batch files we provide from Windows Explorer. To do

that, just follow these steps:

1. Use Windows Explorer to navigate to the C:\Murach\ASP2CS\Database directory.

2. Double-click the db_attach.bat file to run it. This should attach a database named

Halloween to the SQL Server Express database server on the local machine.

3. Right-click the db_grant_access.sql file and select Edit to open it in a text editor.

Then, replace all occurrences of [machineName] with the name of your computer

(MikePC, for example). When youre done, save the file.

4. Double-click the db_grant_access.bat file to run it. This should grant a user named

ASPNET owner access to the Halloween database.

If you encounter problems, you can read the topics that follow to learn more aboutattaching a database and granting the necessary access to ASP.NET.

How to attach the Halloween database from the

command prompt

If you have trouble attaching the database by running the db_attach.bat file from

Windows Explorer, you can run this file from the command prompt instead. Then, you

can see any error messages that are displayed, which will help you troubleshoot any

problems that you may encounter. You can run this batch file from the command prompt

as follows:

1. Start the command prompt (StartAll ProgramsAccessoriesCommand Prompt).

2. Use the cd (change directory) command to navigate to the Database subdirectory of

the directory that holds the applications file (C:\Murach\ASP2CS) like this:

C:\Documents and Settings\Mike>cd \murach\asp2cs\database

3. Run the db_attach.bat file like this:

C:\Murach\ASP2CS\Database>db_attach.bat

The db_attach.bat file uses the sqlcmd tool to run the commands stored in the

db_attach.sql file from SQL Server Express on the local machine. To do that, this bat file

issues a single command:

sqlcmd -S localhost\SQLExpress -E /i db_attach.sql

The sql file creates a database named Halloween and attaches the primary data file

(Halloween.mdf) and the log file (Halloween_log.ldf) to that database. To do that, this

file issues these commands:

create database Halloweenon primary (filename = 'C:\Murach\ASP2CS\Database\Halloween.mdf')log on (filename = 'C:\Murach\ASP2CS\Database\Halloween_log.ldf')

for attachgo

If you decide to store the sample applications in a different directory, you can edit the

db_attach.sql file to specify the correct paths for the Halloween.mdf and

Halloween_log.ldf files.

How to grant ASP.NET access to the database from

the command prompt

If you have trouble granting ASP.NET access to the Halloween database by running

the db_grant_access.bat file from Windows Explorer, you can follow the steps below tomake sure that youve edited this batch file properly. Then, you can run this file from the

command prompt so you can see any error messages that are displayed.

1. Open the db_grant_access.sql file in a text editor.

2. Replace all occurrences of [machineName] with the name of your computer and then

save the file. For example, if you replace [machineName] with MikePC, thecommands in the file will look like this:

sp_grantlogin 'MikePC\ASPNET'go

use Halloweengo

sp_grantlogin 'MikePC\ASPNET'go

sp_grantdbaccess 'MikePC\ASPNET'go

sp_addrolemember 'db_owner', 'MikePC\ASPNET'go

exit

This grants a user named ASPNET on a computer named MikePC access to the

Halloween database.

3. Run the db_grant_access.bat file from the command prompt like this:

C:\Murach\ASP2CS\Database>db_grant_access.bat

This batch file executes the commands stored in the db_grant_access.sql file shown

above.

How to use the sqlcmd tool to execute commands

If necessary, you can use the sqlcmd tool that comes with SQL Server Express to

interactively run the commands that are stored in the sql files. That way, you can run

these commands one at a time to see if they are successful. To do that, start a command

prompt. Then, start the sqlcmd tool like this:C:\Documents and Settings\Mike>sqlcmd -S localhost\SQLExpress

Once the sqlcmd tool is started, you can enter a command like the ones shown on the

previous page. Then, you can type go to execute the command like this:

1> sp_grantlogin 'MikePC\ASPNET'2> go

To end the sqlcmd tool, just type exit.

How to restore the original Halloween database

If you need to restore the original Halloween database, you can do that by runningthe db_restore.bat file, which runs the script stored in the db_restore.sql file. This script

starts by detaching the Halloween database. Then, it copies the original database files,

which are stored in the Original Database directory, over the current files in the Database

directory. Finally, it reattaches the database.

How to detach the Halloween database

If you need to detach the Halloween database from the server, you can do that by

running the db_detach.bat file. For example, if you want to move the mdf and ldf files for

the Halloween database after youve already attached the database, youll need to detach

the database. Then, you can move the files and use an edited version of the db_attach.sqlfile to attach them later.
