Callbacks using C# & DLL's

When callback is required:

1) Sample Application ---------interacts with-------> Library(dll).

2) sample Application calls certain method say STOP() of library.

3) When the task inside method STOP() is over, then if we want to make a reference to a method CALLBACK() of SampleApplication we use the concept of callbacks

2) Create STOP method:

Inside Sample Application

1) When user clicks any button call the STOP() method of the library

2) Recieving callback
