AnalysisStatus.Successful Property
Returns a Boolean summary of the results of the analysis operation.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
Syntax
'Declaration
Public ReadOnly Property Successful As Boolean
'Usage
Dim instance As AnalysisStatus
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.
' Analyze using Afrikaans recognizer.
' You are unlikely to have this recognizer, so it will raise a warning.
Dim afrikaansInkAnalyzer As New InkAnalyzer(theInkCollector.Ink, Me)
Dim afrikaansLanguageId As Integer = 1078
' Access to the Strokes property returns a copy of the Strokes object.
' This copy must be implicitly (via using statement) or explicitly
' disposed of in order to avoid a memory leak.
Dim allStrokes As Strokes = theInkCollector.Ink.Strokes
afrikaansInkAnalyzer.AddStrokes(allStrokes, afrikaansLanguageId)
Dim status As AnalysisStatus = afrikaansInkAnalyzer.Analyze()
' Dispose of the copy of the theInkCollector.Ink.Strokes object
allStrokes.Dispose()
' Display any warnings
