A text editor like notepad / Notepad++ / ... to change the files.
•
The data connection configuration file Bosch.Dcnm.Service.dll.config located in the

The name of the SQL server to use (default: .SQLEXPRESS). This SQL server must be

The connection credentials to connect to the DCN multimedia database. This can be
either windows authentication or SQL authentication.

4.7.2
Formatting of the connection string
To see the format of the connection string we first have to open the configuration file
Bosch.Dcnm.Service.dll.config using a text editor. Search in the configuration file for the
connection string setting DbConnectionString. The default content including surrounding looks
like:
<Bosch.Dcnm.Services.Properties.Settings>
<setting name="DbConnectionString" serializeAs="String">
<value>metadata=res://*; provider=System.Data.SqlClient;provider connection
string="Data Source=.SQLEXPRESS;Initial Catalog=DcnmDatabase;Integrated Security=True;
MultipleActiveResultSets=True";</value>
</setting>
</Bosch.Dcnm.Services.Properties.Settings>
The value content holds the connection string which holds the following information (as separated
by the semicolons).
1. metadata=res://*;
2. provider=System.Data.SqlClient;
3. provider connection string="Data Source=.SQLEXPRESS;Initial
Catalog=DcnmDatabase;Integrated Security=True; MultipleActiveResultSets=True";
The Third part holds the SQL connection string and defines the SQL server and the database. The
shown SQL connection string base on the Windows authentication format and is referring to the
local SQL server named SQLEXPRESS and the database is named DcnmDatabase.
4.7.3
Windows authentication format
The SQL connection string based on Windows authentication has the following format. In the
format the elements to change are marked:
Data Source=.SQLEXPRESS;Initial Catalog=DcnmDatabase;Integrated Security=True;
MultipleActiveResultSets=True
The first mark defines the SQL server. The second mark defines the database name to use.
