12 SOFTKEYBOARD API (C++ API)

Starting with Vista, UIPI (User interface privilege isolation) restricts the way how applications can

interchange windows messages. With UAC (User account control) enabled, softkey.exe runs at an

elevated level, since it is started from a service, and may not receive messages from a standard

application. When using the classic API, a proxy (skbdctrl.exe) receives the global window

messages and talks to the service through a named pipe.

Instead of using the proxy, an application might as well directly use the named pipe to talk to the

service. This API is implemented as a C++ class: CSKCtrl (source files: skctrl.cpp, skctrl.h) and

may be included into existing customer’s applications. An example for using this class is

TestSKCtrl.exe.
