Initializing and Closing a Recognizer
The recognition functions InitRecognizer and CloseRecognizer are obsolete in version 2.0 of the Pen API. In their place, two new
subfunctions have been added to ConfigRecognizer. When the pen system loads a recognizer, it now calls ConfigRecognizer with the subfunction WCR_INITRECOGNIZER. In response to this call, the
recognizer should perform the required initialization tasks formerly conducted by InitRecognizer.
Similarly, the system also calls ConfigRecognizer when it unloads the recognizer, this time with the subfunction
WCR_CLOSERECOGNIZER. This call informs the recognizer it is being unloaded and it should
conduct any required cleanup operations.
Applications based on version 2.0 do not call ConfigRecognizer. This is because the function has no argument that refers to a specific
recognizer of the several that may be currently installed. Instead, version 2.0
applications call the new API function ConfigHREC to configure a recognizer or query for its capabilities. The system
determines the intended recognizer and passes the call on to that recog-nizer's ConfigRecognizer function. Thus, a version 2.0 recognizer exports ConfigRecognizer, which an application accesses by calling ConfigHREC.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
