Our requirement is to interrogate Visual FoxPro application through Windows adapter. Initially we could interrogate nothing.
After research we learnt that enabling GDI configuration in Openspan.ini file would make the interrogation work.
After the configuration changes, all we could achieve so far was to capture only the menus and wasn't able to capture any other controls through Create Control Regions. Control region editor displays a layout of the page with black background and no controls.
FoxPro isn't on the support matrix so we cannot assure full interaction with the application. This may require reaching out to your Pega Account Manager about getting a translator for this application.
