    myParameter.Direction = ParameterDirection.Output
End Sub 'CreateOleDbParameter

[C#] 
public void CreateOleDbParameter() 
 {
    OleDbParameter myParameter = new OleDbParameter("Description", OleDbType.VarChar, 88);
    myParameter.Direction = ParameterDirection.Output;
 }

[C++] 
public:
void CreateOleDbParameter()

    myParameter->Direction = ParameterDirection::Output;
