Who is currently supporting these components/controls? Is there any cost for your “Konopka Signature VCL Controls” and where can they be downloaded from?
I am currently resurrecting a Delphi Application and upgrading it to Delphi 11.2 and it uses some of the Raize Components.
Embarcadero acquired the components back in 2015. The Konopka Signature VCL Controls is available via the GetIt Package Manager within recent versions of Delphi. Startup of the RAD Studio (Delphi) IDE and select the Tools > GetIt Package Manager menu item. Then type “Konopka” into the search box and you will find the entry for KSVC. Click the Install button to install. The source code is installed during the installation.
