WindowsDragSourceMBS.DROPEFFECT_COPY = 1
Type Topic Plugin Version
const Drag & Drop MBS Win Plugin 10.5
Function: One of the drop effect constants.
Notes:
Drop results in a copy. The original data is untouched by the drag source.

Your application should always mask drop effect constants to ensure compatibility with future implementations. Presently, only some of the bit positions in a drop effect value have meaning. In the future, more interpretations for the bits will be added. Drag sources and drop targets should carefully mask these values appropriately before comparing. They should never compare a drop effect value against, say, DROPEFFECT_COPY by doing the following:

if DropEffect = DROPEFFECT_COPY then

Instead, the application should always mask for the value or values being sought as using one of the following techniques:

if bitwiseAnd(DropEffect, DROPEFFECT_COPY) = DROPEFFECT_COPY then

This allows for the definition of new drop effects, while preserving backwards compatibility with existing code.
