ICA Client Object SDK
The ICA Client Object Software Development Kit (ICOSDK) is useful for customizing the operation of the ICA Client. It provides a set of standard scripting interfaces or APIs that allow you to interface with the ICA Client software and control it from third-party applications. ActiveX controls and Netscape Plug-ins are two of the enabling technologies that allow you to embed objects within container applications such as Internet Explorer, Netscape, Microsoft Word, and Excel. The ICA Client Object implementation is based on these two embedding technologies.
Important: The ICA Client Object is included with the Presentation Server (ICA) Client. The files that support ICA Client Object are WFICA.OCX, NPICAN.DLL, and ICACLOBJ.CLASS. These files are installed automatically when the ICA Client is installed. No other files need to be copied and nothing has to be configured to get ICA Client Object working.
