Writing a Recognizer

A recognizer must reflect the developer's requirements, design, and programming style. Although it cannot prescribe any one method for creating a recognizer, this section offers guidance on writing several important recognition functions. The section also presents a sample recognizer called SREC to illustrate some of the information in this chapter.

For a description of how an application uses the InstallRecognizer function to load a recognizer function, see "Creating the HRC" in Chapter 5. The reference section for InstallRecognizer in Chapter 10 also discusses how to load a recognizer by using the LoadLibrary function to aid in debugging the recognizer. To designate a recognizer as the system default recognizer, see "Registry Configuration" in Appendix A.
