DropMaster is a set of 4 native VCL controls for use in Delphi and C++Builder. While the VCL components included with Delphi and C++Builder permit drag and drop between windows in the same application, DropMaster allows developers to add support for drag and drop between applications. The drag and drop can be between the developer's new application and existing applications such as the Microsoft Office suite, a web browser, etc., or between two custom-written applications.
