The Xceed Streaming Compression Library ActiveX control should be available in your development environment's list of available ActiveX controls. The Xceed Component Installer will copy all the necessary files into the library's installation folder (usually in \Program Files\Xceed Components\\Bin\ActiveX) and register the XCEEDSCO.DLL component. Your language should automatically "see" the component. If it does not, then you may need to manually register the control. Before doing this, though, we strongly suggest that you reinstall your copy of the Xceed Streaming Compression Library. This will ensure that it is licensed as well as being registered with the operating system. If that doesn't solve the problem, here's how to manually register the control:
From the Run option in the Windows "start" menu, or from a command prompt, run the following command to register an ActiveX control:
regsvr32 "path and filename of the XCEEDSCO.DLL"
You will then see a message box that either displays "LoadLibrary failed" or displays "LoadLibrary succeeded". If you get the success message, then your ActiveX control is now registered on the machine and is ready for use by applications or in your development environment.
The License method must be called to license the library for runtime use. This applies to both registered users as well as users of a time-limited free trial license.
