OLE Drag and Drop

The aim of this series of tutorials is to enable the reader to implement complete drag and drop support for their applications. Drag and drop became a standard feature of many Windows applications when Windows 95 was launched. With COM and OLE becoming more mainstream at this time, applications had the power to interact seamlessly with the Windows Shell and even other Windows applications. This flexibility came at a price though. Writing any form of COM or OLE enabled appliction is a complete nightmare, to put it mildly.
