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

Maintain Legacy Applications

The ActiveX controls "just work" under most common Windows operating system configurations, so it has been an ideal choice for many companies to maintain legacy applications.

64-Bit Platform Support

Create a better C++ application experience. The 64-bit platform supports more memory allocation to process larger data sets into charts and grids more efficiently. 

Works with Visual Basic and Visual C++

All ActiveX Edition 8.0 controls can be used in VB6 and Visual VC++ applications, and we provide migration utilities for updating older 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.
