ISmartTagExtension.Recognize Method

Searches text in the document for recognized terms.

Namespace:  Microsoft.Office.Tools.Word
Assembly:  Microsoft.Office.Tools.Word (in Microsoft.Office.Tools.Word.dll)

Syntax

'Declaration
Sub Recognize ( _
    text As String, _
    site As ISmartTagRecognizerSite, _
    tokenList As ISmartTagTokenList, _
    context As SmartTagRecognizeContext _
)

void Recognize(
    string text,
    ISmartTagRecognizerSite site,
    ISmartTagTokenList tokenList,
    SmartTagRecognizeContext context
)

Parameters

• text
  Type: System.String
  The text to search for recognized terms.

• site
  Type: Microsoft.Office.Interop.SmartTag.ISmartTagRecognizerSite
  The location of the text in the workbook or document.

• tokenList
  Type: Microsoft.Office.Interop.SmartTag.ISmartTagTokenList
  The text to search for recognized terms, broken down into a list of tokens.

• context
  Type: Microsoft.Office.Tools.Word.SmartTagRecognizeContext
  An object that provides the text from the paragraph that is sent to the recognizer and a method you can call to indicate that the smart tag was found.

Remarks

This method is called by the Visual Studio Tools for Office runtime to search text for recognized terms. Implement this method if you want to incorporate your own search algorithms to run in addition to the standard recognizers.

Examples

The following code example demonstrates how to implement the Recognize method. This implementation compares each smart tag term to the contents of the paragraph. For each smart tag term in the paragraph, the code adds a custom smart tag property and then uses the PersistTag method to recognize the smart tag. This example assumes that you have added a reference to Microsoft.Office.Interop.SmartTag from the .NET tab of the Add Reference dialog box. This code example is part of a larger example provided for the ISmartTagExtension interface.
