AnalysisStatus Class

Represents the status of the analysis operation by indicating the success of the analysis, occurrences of warnings, and where or if any changes occurred.

Example

This example shows how to look for warnings after an ink analysis. When you perform the analysis with the Afrikaans recognizer, which you probably have not installed, the analysis fails with an AnalysisWarningCode value of NoMatchingInkRecognizerFound. In this example, the debugging information is simply sent to the Output window using System.Diagnostics.Debug.WriteLine.

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

Dim status As AnalysisStatus = afrikaansInkAnalyzer.Analyze()

' Note: We should only expect to see the BackgroundException warning if
' we were performing background analysis.
' Display any warnings
If Not status.Successful Then
    ' Initialize warning message
