advanced task panes, Automation add-ins, RTD
Advanced Excel Task Panes
For Excel developers, Add-in Express offers a new, unique technology of Advanced Task Panes. Using this technology you can customize the Excel UI by embedding custom Delphi forms and populating them with any built-in or third-party controls. As a result, you get full-featured custom-tailored Excel plug-ins that work on all Excel versions, across 2000 through Excel 2019 32-bit and 64-bit.
Customize Excel workbooks with your Delphi forms
Advanced Task Panes provided by Add-in Express seamlessly fit into the Excel GUI considering the specificities of each Excel version. The Advanced Excel Task Panes allow you to do without pop-up windows and give you the opportunity to build a first-class Excel user interface (UI) based on modern design and preferences of your end-users.
Excel Real-time Data (RTD) Servers
Another in-demand feature of Add-in Express for Office and Delphi is developing Excel real-time data servers. With Add-in Express you can build Excel RTD servers with any number of RTD topics and use them on any Excel worksheets. Your real-time data can be used in Excel formulas, charts and pivot-tables. See a sample Excel Real-Time Data server project.
Excel Automation add-ins (UDF)
In Excel 2002 - 2016, COM add-ins can be used to develop new worksheets functions (user-defined functions). Such add-ins, called Excel Automation Add-ins, allow you to create new functions used for any purposes. See a sample Excel Automation add-in project.
