Using Connection Managers Inside Custom Log Provider Failing!

Hi,

I'm trying to use an OLE DB connection manager from inside a custom log provider, but can't get the code to work - I get an exception "A first chance exception of type 'System.InvalidCastException' occurred in SSEALogProvider.dll" on the last line of the code below.

I know the connection is OLE DB from looking at .CreationName.

I've tried both with & without ToConnectionManager90(), but appearently not in the right way, both cases gives the same exception.

Any tips on what I'm missing? All the examples I've seen are either creating (instead of using) connection managers, or are file based connection managers. Any and all help much appreciated!



Thanks/Kristian



if (this.ConfigString.Length == 0 || connections.Contains(ConfigString) == false ||

connections[ConfigString].CreationName != "OLEDB")

{

infoEvents.FireError(0, "SSEALogProvider", "The ConnectionManager " + ConfigString + " specified in the ConfigString property cannot be found in the collection, or is of the wrong type (expected CreationName='OLEDB'.)", "", 0);

return Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure;

}

else

[...]



public override void OpenLog()

{

if (!connections.Contains(this.ConfigString))

throw new Exception("The ConnectionManager " + this.ConfigString + " does not exist in the Connections collection.");

ConnectionManager connectionManager = connections[ConfigString];

IDTSConnectionManager90 connectionManager90 = DtsConvert.ToConnectionManager90(connectionManager);

object connObj = connectionManager90.AcquireConnection(null);

//ConnectionManagerOleDb connectionManagerOleDb = (ConnectionManagerOleDb)(connectionManager.InnerObject);

//object connObj = connectionManagerOleDb.AcquireConnection(null);

if (connObj == null)

{

events.FireError(0, "SSEALogProvider", "Could not connect to the log database with connection string " + ConfigString + ".", "", 0);

return;

}

// Exception on next line: "A first chance exception of type 'System.InvalidCastException' occurred in SSEALogProvider.dll"

OleDbConnection oledbConnection = (OleDbConnection)connObj;
