Property Value

The RecognizerGuide to use for ink input.

Remarks

Setting the Guide property succeeds only if the Strokes property is a null reference (Nothing in Visual Basic). You must set the Guide property before you attach a Strokes collection to the Strokes property of the RecognizerContext, or you must set the Strokes property to a null reference (Nothing in Visual Basic) and then set the Guide property.

Note

If you use the latter method, you may need to reattach the Strokes collection to the Strokes property of the RecognizerContext.

The RecognizerCapabilities enumeration contains the FreeInput, LinedInput, and BoxedInput flags. These flags specify the capabilities of a recognizer, but because they are read-only, there is no way to set any of these directly on a Recognizer or RecognizerContext object. The only way to set a recognizer to a specific mode is to set the recognition guide by using the Guide property.

If you do not set the Guide property, the default value is FreeInput mode, assuming that the recognizer is capable of this mode.

The following table lists potential input modes and which values to set the Columns and Rows properties for each mode.

For this type of input	Set the Rows property to	And set the Columns property to
Free input	0	0
Vertical Lined input with 1 line	0	1
Vertical Lined input with n lines	0	n
Horizontal Lined input with 1 line	1	0
Horizontal Lined input with n lines	n	0
Boxed input with 1 box	1	1
Boxed input with n boxes	n	1
Boxed input in a grid of boxes x rows by z columns	x	z

If you set the mode to one that is not available for a Recognizer object, an ArgumentException exception is thrown.

To query which capabilities—or modes—are available from a specific recognizer, use the Capabilities property of the Recognizer object. In Windows Vista, recognizers of Latin script support free input, boxed input, and horizontal lined input; recognizers of East Asian characters support free input and boxed input; and the gesture recognizer supports only free input.

Example

This C# example creates a RecognizerGuide and assigns it to the Guide property of the RecognizerContext object, theRecognizerContext.

theRecognizerContext.Guide = new RecognizerGuide(rows, columns, midline, rectGuide, rectDrawn);

This Microsoft® Visual Basic® .NET example creates a RecognizerGuide and assigns it to the Guide property of the RecognizerContext object, theRecognizerContext.
