+- Implementing uniform data transfer with OLE drag and drop.
 
 The Clipboard is the standard Windows method of transferring data between a source and a destination. It can also be very useful in OLE operations. With the advent of OLE, there are two Clipboard mechanisms in Windows. The standard Windows Clipboard API is still available, but it has been supplemented with the OLE data transfer mechanism. OLE uniform data transfer (UDT) supports Cut, Copy, and Paste with the Clipboard and drag and drop.

 This scenario is implemented by the MFC OLE samples [OCLIENT](../overview/visual-cpp-samples.md) and [HIERSVR](../overview/visual-cpp-samples.md). Look at the source for each application's `CView`-derived class for all but the `GetClipboardData` and `OnGetClipboardData` functions. These two functions are in either the `COleClientItem` or `COleServerItem`-derived class implementations. These sample programs provide a good example of how to implement these concepts.
