Getting Problem In AcquireConnections

Hi All,
I just started looking at the SSIS programming, wanted to created a package having table to table data transfer. My source and destination databases are in Oracle.
I gone throught the code samples and started creating the source component. And the whatever samples i've seen the code i have written (copied) looks correct to me but still getting following error.
The basic questions i have is,
1. Do i need to setup something to start programming in SSIS. I am using 'Microsoft Visual C# Express Edition' for programming.
I have all the dll's in place.



And after compiling the code the exception i got is,


{"Exception from HRESULT: 0xC020801C"} System.Runtime.InteropServices.COMException was caught

Message="Exception from HRESULT: 0xC020801C"

Source="Microsoft.SqlServer.DTSPipelineWrap"

ErrorCode=-1071611876

StackTrace:

at Microsoft.SqlServer.Dts.Pipeline.Wrapper.CManagedComponentWrapperClass.AcquireConnections(Object pTransaction)



The Code is as Follows:

public static void CreateSource()

{

Microsoft.SqlServer.Dts.Runtime.Package package = new Microsoft.SqlServer.Dts.Runtime.Package();

Executable e = package.Executables.Add("DTS.Pipeline.1");

Microsoft.SqlServer.Dts.Runtime.TaskHost thMainPipe = e as Microsoft.SqlServer.Dts.Runtime.TaskHost;

MainPipe dataFlow = thMainPipe.InnerObject as MainPipe;

// Add an OLEDB connection manager that is used by the component to the package.

ConnectionManager cm = package.Connections.Add("OLEDB");

cm.Name = "OLEDB ConnectionManager";

cm.ConnectionString = @"Data Source=pqdb9i;User ID=srcDbUserId;Provider=MSDAORA.1;Persist Security Info=False;Integrated Security=SSPI;Auto Translate=False;";

package.DelayValidation = true;

cm.DelayValidation = true;

component = dataFlow.ComponentMetaDataCollection.New();

component.Name = "OLEDBSource";

component.ComponentClassID = "DTSAdapter.OleDbSource.1";

// Get the design time instance of the component.

CManagedComponentWrapper instance = component.Instantiate();

// Initialize the component

instance.ProvideComponentProperties();

// Specify the connection manager.

if (component.RuntimeConnectionCollection.Count > 0)

{

component.RuntimeConnectionCollection[0].ConnectionManagerID = package.Connections[0].ID;

component.RuntimeConnectionCollection[0].ConnectionManager = DtsConvert.ToConnectionManager90(package.Connections[0]);

}

// Set the custom properties.

//instance.SetComponentProperty("AlwaysUseDefaultCodePage", false);

instance.SetComponentProperty("AccessMode", 2);

instance.SetComponentProperty("SqlCommand", "Select * from srcTable");

// Reinitialize the metadata.

try

{

instance.AcquireConnections(null);

instance.ReinitializeMetaData();

}

catch (Exception ex)

{

Console.WriteLine(ex.Message);

}

Console.WriteLine(component.InputCollection.Count);

}



///End Code
