AnalysisStatus, classe
Mise à jour : November 2007
Représente l'état de l'opération d'analyse, notamment si elle a abouti ou échoué, les avertissements associés et des informations sur l'exécution d'éventuelles modifications (notamment leur emplacement).

Exemples
Cet exemple montre comment rechercher des avertissements après une analyse d'entrée manuscrite. Lorsque vous effectuez l'analyse avec le module de reconnaissance de l'afrikaans, que vous n'avez probablement pas installé, l'analyse échoue avec une valeur NoMatchingInkRecognizerFound pour AnalysisWarningCode. Dans cet exemple, les informations de débogage sont envoyées à la fenêtre Sortie à l'aide de la méthode DebugWriteLine().
