Viewer ActiveX SDK is a fully featured, ready to incorporate facsimile of the End User PDF-XChange Viewer, again embedded within a Window of the developers application, the developer is able to hide and disable most of the controls and functions within the SDK and some GUI tailoring is possible - but Tracker Software branding is present and required from the 'About' Window of the embedded viewer. The ActiveX is also more feature rich than the Simple DLL method.
