示例

下面的示例演示如何在墨迹分析之后查找警告。使用 Afrikaans 识别器(可能您还未安装该识别器)执行分析时,您将发现分析会失败,并返回 InkRecognizerInitializationFailed 警告。

' You are unlikely to have this recognizer, so it will raise a warning.

Dim thePacketCounts As ArrayList = New ArrayList()
Dim thePacketData As ArrayList = New ArrayList()

For Each aStroke In theInkCollector.Ink.Strokes
    ' Add the stroke data to the collections.
