Connection Pooling

Hi...
Can anybody tell me when the connection pool is created ?
What is the max and min pool size ?
Can we do connection pooling using ADO in pure C++ code...

I have written a simple code ...

int main()
{
CoInitialize(NULL);
_ConnectionPtr m_pConnection1;
_ConnectionPtr m_pConnection2;

m_pConnection1.CreateInstance(__uuidof(Connection));

m_pConnection1->Open( "Provider='sqloledb';Data Source='localhost';Initial Catalog='Pubs';Integrated Security='SSPI';Min Pool Size=1;Max Pool Size=10;OLE DB Services=-1", "", "", adConnectUnspecified );
m_pConnection1->Close();
m_pConnection1->Open( "Provider='sqloledb';Data Source='localhost';Initial Catalog='Pubs';Integrated Security='SSPI';Min Pool Size=1;Max Pool Size=10;OLE DB Services=-1", "", "", adConnectUnspecified );
m_pConnection1->Close();

CoUninitialize();
return 0;
}


Is the above code correct ?
