<p class="dtH1">In addition to the configuration information required by the
Enterprise Library Data Access Application Block, EasyObjects.NET uses information in the
configuration file to determine which dynamic query provider to use. Create the configuration information with the
Configuration Console. To use the Configuration Console with EasyObjects.NET,
you will first have to copy the EasyObject DLLs to the same folder as the
Console. </p>
<h4>To copy the configuration DLLs to the Configuration Console folder</h4>
<ol>
<li>Locate the the EasyObjects\bin folder.</li>
<li>Copy the NCI.EasyObjects.dll and
NCI.EasyObjects.Configuration.Design.dll files to the same location as the
Enterprise Library Configuration Console (the default location is C:\Program
Files\Microsoft Enterprise Library June 2005\bin).</li>
<li>To run the Configuration Console, click Start, point
to All Programs, point to Microsoft patterns and practices, point to
Enterprise Library, and then click Configuration Console.</li>
</ol>
<h4>To create the configuration information</h4>
<ol>
<li>If you are starting a new file, click the New
Application icon on the toolbar in the upper-left pane. If you are
opening an existing file, click the Open Existing Application icon.
Right-click the application root node, point to New, and then click Data
Access Application Block Configuration . This generates a Data Access
subtree. (It also generates a Configuration Application Block. For more
information, see the Configuration Application Block documentation.)
</li>
<li>
<p class="dtH1">The default name of the database is Database Instance1.
If you want to change the name, click the Name property field in the
right-hand pane, and then enter the name you want. </li>
<li>
<p class="dtH1">The default database type is SQL Server. If you are
using another type of database, click the SQL Server . In the right-side
pane, click the TypeName property field that displays the fully
qualified name of the SQL Server database. </li>
<li>
<p class="dtH1">Click the Ellipses(...) drop-down box. </li>
<li>
<p class="dtH1">The Type Selector dialog box appears. </li>
<li>
<p class="dtH1">Select from one of the existing database type assemblies
or, if you are using a custom provider, click Load Assembly. </li>
<li>
<p class="dtH1">The default name of the connection string is Connection
String1. Rename the connection string if you want. </li>
<li>
<p class="dtH1">Right-click the name of the connection string. Click
either Password Parameter or Parameter. The Password Parameter option
lets you include a masked password in the connection string as a defense
against someone seeing you enter the password used for connecting to the
database. In either case, the default name is Parameter 1. You can
change the name if you want. </li>
<li>
<p class="dtH1">If you clicked Parameter go to step 12. If you clicked
Password Parameter, click Parameter 1, click the Masked Value property
field in the right-side pane. </li>
<li>
<p class="dtH1">Click the Ellipses(...) drop-down box. The Set Password
dialog box appears. </li>
<li>
<p class="dtH1">Enter the password. Confirm the password. Click OK. Note
that the parameter is saved as plain text. If you want to hide it you
must turn on encryption. To learn how to do this, refer to the
Configuration Application Block documentation. </li>
<li>
<p class="dtH1">If you clicked Parameter, click Parameter 1, and then
click the Value property field in the right-side pane. Enter the value.
</li>
<li>
<p class="dtH1">The default for Integrated Security is True . With
integrated security, a network user can access a SQL Server database
without supplying a separate logon identification or password because
SQL Server obtains the user and password information from Windows. If
you want to turn off Integrated Security, click Integrated Security,
click the Value field in the right-side pane, and then change the value
to False. </li>
<li>
<p class="dtH1">The default value for the connection string data source
is server. You can change this if you want by clicking server ,
right-clicking in the Value field in the right-side pane and entering
the new name. You can also right-click server, click Rename, and then
enter the new name. </li>
<li>
<p class="dtH1">The default value for the database name is database. You
can change this if you want by clicking database , right-clicking the
Value field in the right-side pane and entering the new name. You can
also right-click server, click Rename and enter the new name. </li>
<li>
<p class="dtH1">Right-click the application root node, point to New, and
then click EasyObjects.NET Dynamic Query Provider . This generates an
EasyObjects.NET subtree.</li>
<li>
<p class="dtH1">The default database type is SQL Server. If you are
using another type of database, click the SQL Server . In the right-side
pane, click the TypeName property field that displays the fully
qualified name of the SQL Server database. </li>
<li>
<p class="dtH1">Click the Ellipses(...) drop-down box. </li>
<li>
<p class="dtH1">The Type Selector dialog box appears. </li>
<li>
<p class="dtH1">Select from one of the existing database type assemblies
or, if you are using a custom provider, click Load Assembly. </li>
<li>
<p class="dtH1">The default value for the dynamic query instance name is
Dynamic Query Instance. You
can change this if you want by clicking dynamic query instance, right-clicking the
Value field in the right-side pane and entering the new name. You can
also right-click Dynamic Query Instance, click Rename and enter the new name. </li>
<li>
<p class="dtH1">Save the changes.</li>
</ol>
<h4>Usage Notes</h4>
<p class="dtH1">The Configuration Console creates a configuration file for each application
block and for EasyObjects. The application configuration file (typically named either App.config or
Web.config) contains information about which application blocks the application
is configured to use and the path of those configuration
files. By default, the path of each configuration file is
the current directory of the application configuration file.</p>
<p class="dtH1">When you use the Configuration Console to open the App.config file and change
configuration settings, the modified application block configuration files are
saved to the same directory as the App.config file. However, each time a project
successfully builds, Visual Studio automatically copies the App.config file to
the target directory and renames it to executable .exe.config. This means you
must also copy the relevant configuration files to the target
directory.
</p>
<p class="dtH1">You can copy the application block configuration files to the target directory
either manually or use the Visual Studio Build Events property to have them be
copied each time the project is built. To make sure all block configuration
files are copied to the proper directory, use the following command as the
post-build event command line:</p>
<p class="dtH1"><pre>copy "$(ProjectDir)*.config" "$(TargetDir)"</pre>
