Update and maintain your legacy applications faster and better with the only control collection for ActiveX
Our goal is to empower our developers, and one way we do so is to address critical issues quickly. Visual Basic 6.0 applications were built using our ActiveX controls and continue to run on supported Windows versions. We do our best to suggest workarounds when cases arise where the functionality of Windows versions differs. However, we cannot guarantee the same functionality for ActiveX controls across every Windows version. We are committed to Microsoft "It Just Works" compatibility for our ActiveX controls for Windows 7, 8,1, and 10, Window Servers 2008, 2012, 2016, 2019.
Maintain Legacy Applications
The ideal choice for updating and maintaining legacy applications. We are committed to Microsoft's "It Just Works" compatibility for our ActiveX controls.
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.
VSFlexGrid supports several binding formats (ADO/OLEDB, DAO, 2D and 3D arrays, and other VSFlexGrids). You can also connect the grid to a variant array or a custom, self-developed data source. Subtotaling, advanced data validation, input masks, and column locking are also all supported. 64-bit version included.
Create sophisticated 2D and 3D charts and graphs with fast, real-time tracking and flexible data binding, and serve your charts as JPEG or PNG images. Get all the robust, time-saving, easy-to-use features you expect, such as data binding to any data source, often without writing a line of code. Distribute your charts royalty-free. 64-bit version included.
VSView 8.0 Reporting
Our VSView 8.0 Reporting control is flexible and easy to implement. You can quickly and easily create Microsoft Access-style database reports for your Visual Basic, VC++, and C++Builder applications, as well as preview, print, and export those reports on your computer or over the web. 64-bit version included.
