VB.NET Core Classes in a Nutshell

Name

Overlapped

Synopsis

This class encapsulates the Win32 API OVERLAPPED structure. NativeOverlapped is needed to mimic the structure the API expects, but this class encapsulates the overlapped structure into a .NET class. You can create NativeOverlapped structures by calling Pack(), and create Overlapped objects with the shared Unpack() method. To avoid a memory leak, each NativeOverlapped that you create must also be freed by calling the sharedFree() method. Unpack() does not free the memory.
