ActiveX Support Guide

Follows Microsoft "It Just Works" compatibility for ActiveX controls on Windows 7, 8, 10, 11, Window Servers 2008, 2012, 2016, 2019.

Due to changes in the Windows operating system and Microsoft's end of support, we can no longer fully support and provide maintenance builds of ActiveX controls.

You can download and license the latest version of ActiveX Edition from the C1ControlPanel application.



You can request a free meeting with a product manager to discuss support and migration options.

ComponentOne for ActiveX Key Features

Legacy application maintenance

It's the ideal choice for updating and maintaining legacy applications. We're committed to Microsoft's "It Just Works" compatibility with ActiveX controls.

64-bit platform support

Build a better application experience with the larger memory allocation of 64-bit platforms. By caching data in memory, you can more efficiently process larger data sets with charts and grids. VSFlexGrid, VSView reporting, queries, and charts all support 64-bit.

High compatibility with Visual Basic and Visual C

All ComponentOne for ActiveX 8.0 controls are available for use in VB6 and Visual VC applications, and we also provide a migration utility to update previous versions to 8.0.

VSFlexGrid 8.0

VSFlexGrid supports binding formats such as ADO/OLEDB, DAO, 2D and 3D arrays, allowing the grid to connect to a variety of arrays and user-defined data sources. It also supports subtotals, advanced data visualization, input masks, and column fixation. VSFlexGrid fully supports 64-bit.

Chart 8.0

Create sophisticated 2D and 3D charts and graphs with fast, real-time tracking and flexible data binding, and deliver them as JPEG or PNG images. Enjoy powerful, time-saving, and easy-to-use features. Data binding to any data source is possible without writing any code. ActiveX charts fully support 64-bit.

VSView 8.0 Reporting

The VSView 8.0 reporting control is flexible and easy to implement. It allows you to quickly and easily generate Microsoft Access-style database reports for Visual Basic, VC , and C Builder applications, and preview, print, and export those reports on your computer or the web. A 64-bit version is included.
