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 boolean get_Successful ()
public function get Successful () : boolean
Not applicable.
Property Value
true if the analysis operation completed without any warnings. false if at least one warning occurred.
Example
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 NoMatchingInkRecognizerFound warning. This means that the Successful property is false. In this simple example, the debugging information is simply sent to the output window using WriteLine.
