Any application that you develop can use SftBox/OCX royalty-free in run-time only mode; design-time features are not available. Each user (developer) who needs access to design-time and compile-time features must license a copy of SftBox/OCX.

Source Code

The source code for the control and property pages (written in Microsoft Visual C++ using the ATL framework) is optionally available under our Enterprise Licensing program. Any application that you develop can use SftBox/OCX royalty-free (some restrictions apply), as long as only the redistributable files are shipped with your application.

Languages Supported

SftBox/OCX supports all popular ActiveX (OCX) platforms, such as Visual Studio .NET, Visual Basic, Visual C++ and many more. Feature limitations may exist depending on the platform used. These are generally caused by the platform, rather than our control product, which implements the current ActiveX control standards specifications.

Environments Supported

SftBox/OCX supports Windows 2000 through Windows 10 including their server editions using the same set of properties, events and methods.

UNICODE support is available for all platforms.

Windows 98 and Windows ME are no longer supported. For support of these platforms, SftBox/OCX 4.5 must be used instead.
