Public Property AssertUiEnabled As Boolean
Property Value
true
if user-interface mode is enabled; otherwise, false
.
Examples
The following code example calls a function that calls the Fail(String, String) method to log an error message if the function throws an exception. If the AssertUiEnabled property is false
, the method also writes the error message to the console.
// Compute the next binomial coefficient and handle all exceptions.
try
{
result = CalcBinomial(possibilities, iter);
}
catch(Exception ex)
{
string failMessage = String.Format("An exception was raised when " +
"calculating Binomial( {0}, {1} ).", possibilities, iter);
defaultListener.Fail(failMessage, ex.Message);
if (!defaultListener.AssertUiEnabled)
{
Console.WriteLine(failMessage+ "\n" +ex.Message);
}
return;
}
' Compute the next binomial coefficient and handle all exceptions.
Try
result = CalcBinomial(possibilities, iter)
Catch ex As Exception
Dim failMessage As String = String.Format( _
"An exception was raised when " & _
"calculating Binomial( {0}, {1} ).", _
possibilities, iter)
defaultListener.Fail(failmessage, ex.Message)
If Not defaultListener.AssertUiEnabled Then
Console.WriteLine(failMessage & vbCrLf & ex.Message)
End If
Return
End Try
