Info

Following are features of Static/Shared classes :- √ √ √ √ They can not be instantiated.By default a object is created on the first method call to that object. Static/Shared classes can not be inherited. Static/Shared classes can have only static members. Static/Shared classes can have only static constructor. Note :- In CD there is a folder “WindowsShared” which has a sample code for shared variables.Below is a snippet.It has a “AddCount” function which increments a static “intCount” variable.In form there are two buttons which creates a new object and displays the count of the static variable.Even though the object is created and destroyed , the variable values does not change.It retains its old value. Public Class ClsShared Shared intCount As Integer Public Function AddCount() As Integer intCount = intCount + 1 Return intCount End Function End Class Public Class FrmSharedClasses Inherits System.Windows.Forms.Form Private Sub CmdInstance1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CmdInstance1.Click Dim pobjClsShared As New ClsShared() MessageBox.Show(“The count at this moment is” & pobjClsShared.AddCount.ToString()) End Sub Private Sub CmdInstance2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CmdInstance2.Click Dim pobjClsShared As New ClsShared() MessageBox.Show(“The count at this moment is” & pobjClsShared.AddCount.ToString()) End Sub End Class 112 * Can you explain logic of binary sort ?
Figure :- 6.7 Shared/Static In Action (B) What is Dispose method in .NET ? .NET provides “Finalize” method in which we can clean up our resources.But relying on this is not always good so the best is to implement “Idisposable” interface and implement the “Dispose” method where you can put your clean up routines. (B) Whats the use of “OverRides” and “Overridable” keywords ? Overridable is used in parent class to indicate that a method can be overridden.Overrides is used in the child class to indicate that you are overriding a method (A) Where are all .NET Collection classes located ? System.Collection namespace has all the collection classes available in .NET. (A) What is ArrayList ? *Whats difference between procedural and object oriented programming ? 113
