The factory implementation returns the list of supported controls, creates controls on request and provides information about the unique IDs of the COM classes and interfaces for each control.

      QAXFACTORY_EXPORT( ActiveQtFactory, "{3B756301-0075-4E40-8BE8-5A81DE2426B7}", "{AB068077-4924-406a-BBAF-42D91C8727DD}" )

The factory is exported using the QAXFACTORY_EXPORT macro.

To build the example you must first build the QAxServer library. Then run `qmake` and your make tool in `examples/activeqt/wrapper`.

The demonstration requires a web browser that supports ActiveX controls, and scripting to be enabled.
