Add-in Express Description:

Add-in Express is a tool for creating Microsoft Office COM add-ins in Delphi. Using it you can develop a single add-in that will run across the entire Office suite of applications - MS Excel, Word, PowerPoint, Outlook, Access, FrontPage and MS Project.
Add-in Express hides complexity of implementing the IDTExtensibility2 interface that COM add-in architecture is based on. And using Add-in Express, add-in projects can be created by a couple of clicks. You create your own toolbars and place buttons, edit boxes, combo boxes, and pop-ups onto them.
Add-in Express correctly handles hiding and deleting controls, as well as moving them to other toolbars. It also allows handling the controls' events. Use Delphi forms, standard controls and components to develop a COM add-in.
Quick Demo project includes a sample COM add-in for all supported apps that creates a number of toolbars and controls. You get the source code of the sample add-in where you see the use of Office Add-in Express classes as well as details of toolbar and control creation.
