>I learn how to output to HTML through the OBJECT parameter in the REPORT FORM command. I understand it uses VCX Class _reportlistener.vcx. I copy it to my application data folder, but it keeps return an error of missing variable. If I point to FFC folder, where there are a lot of other VCX, it works fine.
>Does anyone knows which VCX I must copy to get it to work without the entire FFC folder?

You don't need any VCX

loListener = Null
DO (_REPORTOUTPUT) WITH 5, loListener
loListener.TargetFileName = 'MyReport.html'
loListener.QUIETMODE = .T.
