IDbConnectionExtension Interface
Represents additional connection properties that can be implemented by SQL Server Reporting Services data processing extensions.

Syntax
'Declaration
Public Interface IDbConnectionExtension _
Inherits IDbConnection, IDisposable, IExtension
'Usage
Dim instance As IDbConnectionExtension
public interface IDbConnectionExtension : IDbConnection,
IDisposable, IExtension
public interface class IDbConnectionExtension : IDbConnection,

The IDbConnectionExtension type exposes the following members.
Properties
| Name | Description | |
|---|---|---|

ConnectionString | Gets or sets the string used to open a database. (Inherited from IDbConnection.) |
|
ConnectionTimeout | Gets the time to wait, while trying to establish a connection, before terminating the attempt and generating an error. (Inherited from IDbConnection.) |
|
Impersonate | Sets the username of the user that is impersonated while queries are executed. This property is ignored by the report server if impersonation is not supported by the data provider. |
|
IntegratedSecurity | Indicates whether the connection should use integrated security rather than supply a username and password. |
|
LocalizedName | Gets the localized name of the extension to be displayed in a user interface. (Inherited from IExtension.) |
|
Password | Gets or sets the password to use when connecting to the database. Overrides any password specified in the connection string. |
|
UserName | Gets or sets the username to use when connecting to the database. Overrides any username specified in the connection string. |

BeginTransaction | Begins a database transaction. (Inherited from IDbConnection.) |
|
Close | Closes the connection to the database. (Inherited from IDbConnection.) |
|
CreateCommand | Creates and returns a Command object associated with the connection. (Inherited from IDbConnection.) |
|
Dispose | (Inherited from IDisposable.) |
|
Open | Initializes a database connection with the settings specified by the ConnectionString property of the provider-specific Connection object. (Inherited from IDbConnection.) |
|
SetConfiguration | Used to pass custom configuration data to an extension. (Inherited from IExtension.) |

Remarks
The IDbConnectionExtension interface enables you to implement an extension of the IDbConnection interface, which adds additional functionality for authenticating a connection to a data source. The IDbConnectionExtension interface can be used to build a custom data processing extension. For more information about Connection classes, see Implementing a Connection Class for a Data Processing Extension.
An application does not create an instance of the IDbConnectionExtension interface directly, but creates an instance of a class that implements IDbConnectionExtension.
Classes that implement IDbConnectionExtension must also implement all required members, and typically define additional members to add provider-specific functionality. Because IDbConnectionExtension inherits from IDbConnection, you must also implement all of the IDbConnection members as part of your Connection class including those members from IExtension.
