New Post: How can I add Legend Controls for MapWinGIS ActiveX 4.9.1

I have downloaded the latest MapWinGIS 4.9.1 Alpha. I got a problem of adding legend control to my application. The MapWinInterfaces.dll 4.8 is no longer used. LegendControl cannot be loaded.
Could you tell me how to load a legend component for the MapWinGIS 4.9.1?
Thank you for your help.
