Answer all the questions

Question. 1. Explain the process of extracting and drawing images using Image list control.

Answer: An ImageList control contains a collection of images that can be used by other Windows Common Controls — specifically, the ListView, TreeView, TabStrip, and Toolbar controls. For example, the ImageList control can store all the images that appear on a Toolbar control's buttons.

The ImageList control can also be used with controls that assign a Picture object to a Picture property, such as the PictureBox, Image, and CommandButton controls.

Question. 2. Explain the concept of Inheritance in VB.Net.

Answer: When we say inheritance in Visual Basic .NET, we mean that a child gets a copy of everything found in a parent plus anything we add to that child. Technically, a child gets a copy of the data and access to a methods table, but for simplicity we think of child classes as getting their own copy of everything. This does not mean that a child can directly access every member inherited from the parent; access rules still apply. The child gets a copy of everything, but can only directly access public, protected, and friend members of a parent. Because private members represent implementation details, a child class is usually interacting with private members indirectly via public, protected, or friend members.

Although SQL is both an ANSI and an ISO standard, many database products support SQL with proprietary extensions to the standard language. Queries take the form of a command language that lets you select, insert, update, find out the location of data, and so forth. There is also a programming interface.

Question. 5. Describe the concept of record navigation in VB.NET.

Answer: NavigateRecords() : Our Subroutine is where the action takes place, and the values from the DataSet are placed in the textboxes. Here it is again:

Private Sub NavigateRecords()

txtFirstName.Text = ds.Tables("AddressBook").Rows(inc).Item(1)

txtSurname.Text = ds.Tables("AddressBook").Rows(inc).Item(2)

End Sub
