There may be times when you want to make sure the base class will call its own method implementation, even though the client is using an object instance of the derived class. In this situation, the MyClass qualifier prefaces the call to the overridden base class method. In the following code, a call is made to a method that determines the account s average balance for the month. Depending on the result, the CalculateInterest method of the class will either call its own implementation of the GetInterestRate method or the derived class s implementation. Public Class CheckingAccount Public Function GetAverageBalance() As Double Dim dblAverageBalance as Double 'Determine average monthly balance Return dblAverageBalance End Function Public Overridable Function GetInterestRate() As Single Dim sngInterestRate as Single 'Retrieve current rate Return sngInterestRate End Function Public Sub CalculateInterest(ByVal Amount As Double) Dim sngInterestRate as Single If GetAverageBalance() < 1000 then 'Call the current class method sngInterestRate = MyClass.GetInterestRate() Else 'Call the derived class method sngInterestRate = Me.GetInterestRate() End If 'Code continues. . . End Sub End Class Be careful not to confuse the MyClass qualifier with the Me qualifier. The Me qualifier is the default qualifier if none is used. When the Me qualifier is used, the most derived class implementation of the method is executed. This is different from the MyClass qualifier, which will use the current class s implementation. c# pdf library open source: Free . NET PDF Component - Developing PDF in C# , VB.

Example 5-18 is useful when you want to hear what the Microsoft speech recognition engine hears. You can use whatever voice you want. Here I m using the MicrosoftVoice to repeat what it hears. Example 5-18.

In some cases, you may want to develop a derived class method that still uses the implementation code in the base class but also augments it with its own implementation code. In this case, you create an overriding method in the derived class and call the code in the base class using the MyBase qualifier. The following code demonstrates the use of the MyBase qualifier: Public Overrides Sub Deposit(ByVal Amount As Double) 'Derived class implementation code 'Call to base class implementation MyBase.Deposit(Amount) This command line draws a simple stick-figure man and some text: convert -fill blue -font mailrays.ttf -pointsize 96 -draw "circle 100,100 125,125 rectangle 65,150 135,300 text 200,300 Water" input.jpg output.jpg } catch (Exception e) { //print error and exit. e.printStackTrace(); System.exit(1); } } } In this section, I showed two examples of using speech recognition, both of which implemented the JRecognizer interface. The first used Sphinx-4 for Java to demonstrate command and control. The second used JNI and the Microsoft speech recognition engine to give an example of continuous dictation. Before introducing the first example, I gave a brief overview of the Java Speech Grammar Format (JSGF). This is the format of what words the recognizer needs to understand. The classes discussed were SphinxSR: This is the Java recognizer using command and control. MicrosoftSR: This is the continuous recognizer using JNI and Microsoft speech recognition engine. (You must train this engine prior to use.) This gives you the final image shown in Figure 7-52 to use for comparisons.
