Property Value

A collection of AnalysisWarning objects in which each AnalysisWarning object describes a particular warning or error.

Remarks

Each AnalysisWarning object describes a particular warning or error.

The AnalysisWarningCode enumeration describes the types of warnings that can occur during ink analysis.

Some warnings are fatal, which means that the InkAnalyzer must be re-instantiated, while others are not.

Example

The following example shows how to:

Loop through the warnings in an AnalysisStatus object, status.
React to each warning.
Collect the warning information into a message string, message.

' Loop through warnings
