twinBASIC Fusion Technology

twinBASIC Beta release 976 introduces the long-awaited “Fusion” technology - enabling 64-bit projects to host certain 32-bit ActiveX controls via an automatically generated out-of-process host EXE.

Fusion is a twinBASIC feature that enables 64-bit applications to host certain 32-bit ActiveX controls by transparently bridging them through an out-of-process helper executable.

Traditionally, ActiveX controls must match the bitness of the host application. This limitation has long prevented the use of legacy 32-bit controls in modern 64-bit applications. Fusion removes this restriction by introducing a bridging layer that allows cross-architecture interaction.

Please note: this technology has currently only been tested on Windows 10 and 11 machines. Results may vary on older operating systems.

What does "out-of-process" mean?
An out-of-process component runs in a separate executable (process) rather than within the same memory space as the main application.

With twinBASIC Fusion:

Your main twinBASIC application runs as usual (e.g. 64-bit)
A secondary host EXE is launched automatically (e.g. 32-bit)
The ActiveX controls are created and hosted inside this secondary process
Communication between your main application and the controls is handled transparently by twinBASIC

This separation allows incompatible architectures (e.g. 32-bit controls in a 64-bit app) to interoperate safely.
