AcquireConnection returns null value

I have the following code in my custom source component's AcquireConnection method -

if (ComponentMetaData.RuntimeConnectionCollection[0].ConnectionManager != null)

{

ConnectionManager cm = Microsoft.SqlServer.Dts.Runtime.DtsConvert.ToConnectionManager(ComponentMetaData.RuntimeConnectionCollection[0].ConnectionManager);

ConnectionManagerAdoNet cmado = cm.InnerObject as ConnectionManagerAdoNet;

if (cmado == null)

throw new Exception("The ConnectionManager " + cm.Name + " is not an ADO.NET connection.");

// Get the underlying connection object.
this.oledbConnection = cmado.AcquireConnection(transaction) as OleDbConnection;

if (oledbConnection == null)

throw new Exception("The ConnectionManager is not an ADO.NET connection.");

isConnected = true;

}

The value of oledbConnection is null.

I am trying to invoke the above method within a package that I am trying to create dynamically. Any help ?

private const string ADONETConnectionString = "Provider=SQLOLEDB.1;Data Source={0};Initial Catalog={1};Integrated Security=True;";

ConnectionManager PubTRCM = package.Connections.Add("ADO.NET:OLEDB");

PubTRCM.Name = "PubTR";

PubTRCM.ConnectionString = String.Format(ADONETConnectionString, paramPubServer, paramPubTRDB);

#region Create OLEDB Source Component

//Create a OLEDB Source Component
IDTSComponentMetaData90 Source = dataFlow.ComponentMetaDataCollection.New();
Source.Name = "OLEDBSource";

Source.ComponentClassID = typeof(Microsoft.Samples.SqlServer.Dts.AdoSourceSample).AssemblyQualifiedName;

//Get the design time instance of the source
CManagedComponentWrapper SourceDesignTime = Source.Instantiate();

//Initialize the component
SourceDesignTime.ProvideComponentProperties();

if (Source.RuntimeConnectionCollection.Count > 0)
{
Source.RuntimeConnectionCollection[0].ConnectionManagerID = PubTRCM.ID;
Source.RuntimeConnectionCollection[0].ConnectionManager = DtsConvert.ToConnectionManager90(PubTRCM);
}

SourceDesignTime.SetComponentProperty("SqlStatement", "Select PlantId from PlantDim");

//Reinitialize the metadata
SourceDesignTime.AcquireConnections(null);
SourceDesignTime.ReinitializeMetaData();
SourceDesignTime.ReleaseConnections();

#endregion

So what stage does the problem start? Is cmado an object? If so what type? What is the result from cmado.AcquireConnection, never mind the cast?

Have you tried debugging your component whilst it is being called like this?

Does the component work in the designer, I assume not.

I could resolve this problem by changing the connection string from -

"Provider=SQLOLEDB.1;Data Source={0};Initial Catalog={1};Integrated Security=True;";

to

"Provider=SQLOLEDB.1;Data Source={0};Initial Catalog={1};Integrated Security=SSPI;";

and adding the connection manager to the package as follows -

ConnectionManager CMgr = package.Connections.Add("ADO.NETystem.Data.OleDb.OleDbConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");
