At the moment I store connection strings externally, but I keep finding hard-coded connection strings all over the web.config xml, various providers etc. It's driving me crazy. Thank you

• COM Dual Interfaces

  - by Tony

  A dual interface in COM is one that is able to be accessed via a DispInterface or via VTable methods. Now can someone tell me what is exactly what the difference is between the two methods? I thought that a VTable is a virtual table which holds the pointers to the different functions when implementing a class hierarchy which has virtual functions that can be overridden in child classes.
