Re: DnD vs CnP (was Copy/Paste Events)

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.

Note that Windows really does lump clipboard and drag and drop together.

No, I'm sorry you're unaware of how other operating systems work.

How data is inserted into a data source depends on whether the data is
supplied immediately or on demand, and in which medium it is supplied.
The possibilities are as follows.

Supplying Data on Demand (Delayed Rendering)

In the Data on Demand/Delayed Rendering case, the data does not
survive app death (unless the app chooses to force the data onto the
clipboard immediately before death).
