Create a C# DLL exporting a method that returns time of the day as string and also perform callbacks (every 2 minutes) by passing a boolean value 'true' to the 'statusUpdated' method in client apps. Create three dummy client apps in (C#, vb6, vc6) that have a simple callback method named 'statusUpdated' which takes a single parameter of int. And put up a messagebox each time when they receive callbacks from the C# DLL. Recap, basically a simple managed dll (C#) that expose one method 'getTime()'. And three dummy skeleton client apps in C#, VB6,VC++ that have one callback method 'statusUpdated()' that gets called from the c# dll every 2 minutes and within the statusUpdated() call the dll's getTime() and display the result in a messagebox.
