Microsoft Drag-Drop Server Strategy

The information in this article applies to:

• Microsoft Windows Software Development Kit (SDK) for Windows version 3.1

Windows version 3.1 supports a drag-drop protocol that enables an application to be the client of File Manager. When an application implements the drag-drop feature, a user can select one or more files in File Manager, drag them to a client application, and drop them. At this point, the client application receives a message and it can determine which files were dropped and the exact location at which the files were dropped.

At present, version 3.1 of the File Manager is the only server application that supports the drag-drop protocol. Although no Windows function is available to enable an application to become a drag-drop server, Microsoft intends to provide this functionality in a future release of Windows.

The drag-drop interface mechanism will change to provide additional functionality that can be used by a future server application to support application cooperation and shell integration. The new mechanism will continue to support the Windows 3.1 drag-drop client protocol.
