AnalysisStatusBase.Successful Property
Returns a Boolean summary of the results of the analysis operation.
Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)
Syntax
'Declaration
Public ReadOnly Property Successful As Boolean
'Usage
Dim instance As AnalysisStatusBase
Dim value As Boolean
value = instance.Successful
public bool Successful { get; }
public:
property bool Successful {
bool get ();
}
public function get Successful () : boolean
Property Value
Type: System.Boolean
true if the analysis operation completed without any warnings. false if at least one warning occurred.
Examples
The following 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 a InkRecognizerInitializationFailed warning. This means that the Successful property is false. In this simple example, the debugging information is simply sent to the output window using Debug.WriteLine.

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