Recognize
- 0 2.0
Begins sampling pen data and converts tablet input to recognized symbols.
Note This function is provided only for compatibility with version 1.0 of the Pen
API and will not be supported in future versions.
REC Recognize( LPRC lprc )
Parameters
lprc
Address of an RC structure.
Return Value
Returns an REC_ value. See the "Comments" section for a description of the
return values.7
Comments
The RC structure that lprc points to contains the parameters that control recognition. The system sends
recognition results via the WM_RCRESULT message to the window indicated by the hwnd member of the RC. All results messages are sent before Recognize returns. Multiple result messages can be sent if the application asks for
results to be sent to the application before all input has been completed (as
indicated by the wResultMode member of the RC structure).
An application that uses version 1.0 recognizers should call Recognize when the input session begins, signaled by the WM_LBUTTONDOWN message.
The value REC_OK is used in the wParam of the WM_RCRESULT message to indicate that more data is coming. Return
values of greater than 0 signal normal successful completion. Return values of less
than 0 indicate abnormal termination. Return values of less than REC_DEBUG are
reserved for return values from
debugging versions of the system or recognizer. If an application creates a
condition that would be caught in a debugging version while running a
nondebugging version, the results are undefined.
Each return value can be the wParam value of the WM_RCRESULT message or the return value for Recognize. The wParam value of the last WM_RCRESULT message generated by a call to Recognize is the return value of Recognize. Some error conditions, such as REC_OOM or REC_NOTABLET, are returned without
generating any corresponding WM_RCRESULT message.
All of the values listed in the following table are in the debug version only.
No WM_RCRESULT message is generated if these values are returned by Recognize.

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 » |
