Function GetKey( _
   ByVal keyName As String, _
   ByVal keyExtension As String, _
   ByVal onServer As Boolean _
) As IDataSourceKey

Visual Basic (Usage)	Copy Code
Dim instance As IDataSourceKeyResolver Dim keyName As String Dim keyExtension As String Dim onServer As Boolean Dim value As IDataSourceKey   value = instance.GetKey(keyName, keyExtension, onServer)

IDataSourceKey GetKey( 
   string keyName,
   string keyExtension,
   bool onServer
)

IDataSourceKey^ GetKey( 
   String^ keyName,
   String^ keyExtension,
   bool onServer
) 

Parameters

keyName

Data source key name

keyExtension

Extension or empty string

onServer

True if called from the EntityServer

Return Value

GetKey will be called once per keyName and keyExtension on both the client and server. If you need to secure your client connection information you may want to implement separate versions of this class on the client and server tiers.

The IDataSourceKey returned is stored in a map, and the same key is reused whenever the same key name and extension are encountered. Note that on the server this means that the same key will be used by any users of your application: user-specific keys are not supported.

Any exception thrown in your GetKey implementation will be returned to the calling client.
