Remarks

Because so many variations exist between users' handwriting, handwriting recognizers can sometimes convert handwriting into text that is different from what the user intended. When an InkAnalyzerBase performs analysis on a collection of strokes, the InkAnalyzerBase finds the most likely set of words that the handwriting represents. In addition, the InkAnalyzerBase also finds sets of alternative recognition matches, which are stored in an AnalysisAlternateBaseCollection. In order for a user to take advantage of recognition alternates, you must create a user interface that allows the user to select the correct AnalysisAlternateBase.

AnalysisAlternateBase objects are generally obtained through the InkAnalyzerBase.GetAlternates method. The first AnalysisAlternateBase object in the collection is what the InkAnalyzerBase considers to be the most likely alternate.

Example

This example calls InkAnalyzerBase.GetAlternates on an InkAnalyzerBase, theInkAnalyzerBase. It then loops through the AnalysisAlternateBaseCollection and populates a T:System.Windows.Forms.ListBox, alternatesListBox, with all of the alternates that do not have an InkRecognitionConfidence value of Poor.

alternatesListBox.Items.Clear()
Me.currentAlternates = theInkAnalyzerBase.GetAlternates(selectedSubNodes)
Dim alternate As AnalysisAlternateBase
For Each alternate In Me.currentAlternates
    ' Add only those that are not Poor confidence
    If alternate.InkRecognitionConfidence <> System.Windows.Ink.AnalysisCore.InkRecognitionConfidence.Poor Then
        alternatesListBox.Items.Add(alternate.RecognizedString)
    End If
Next alternate

alternatesListBox.Items.Clear();
this.currentAlternates = theInkAnalyzerBase.GetAlternates(selectedSubNodes);
foreach (AnalysisAlternateBase alternate in this.currentAlternates)
{
    // Add only those that are not Poor confidence
    if (alternate.InkRecognitionConfidence !=
        System.Windows.Ink.AnalysisCore.InkRecognitionConfidence.Poor)
    {
        alternatesListBox.Items.Add(alternate.RecognizedString);
    }
}
