39. Message box - MSGBOX MsgBox ( " This is Visual Basic.Net Course") Or use it with msgbox style msgbox( " I am about to do something", MsgBoxStyle.OKCancel ) msgbox( " Are You Ahmed? ", MsgBoxStyle.YesNo ) The general form of msgbox is: Msgbox(“title”,”prompt”, msgstyle)

40. INPUT BOX General form of inputbox : Inputbox (“ prompt”, “inputbox title”) Example: InputBox( " What is Your Name ? ", " Student Name " )

41. IF STATEMENT There are three kinds of if statements: 1. Simple if then: IF ( CONDITION ) THEN STSTEMENT ENDIF 2. If else: IF ( CONDITION) THEN STSTEMENT1 ELSE STATEMENT2 ENDIF 3.

53. LIST BOX & COMBO BOX  List box is an object which represents an array of text.  Each item has unique index.  Combo box is the most similar component to list box with one item shown.  List box could be filled during design and run time.  Design time fill: property  items  collection  text.  Run time fill: by using ( listbox1.items.insert( ), or listbox1.items.add( ) )

54. Design the following form with buttons and list box as shown

List box operations and codes '1- add AAA FIRST: ListBox1.Items.Insert(0, "AAA") '2- add AAA LAST: ListBox1.Items.Insert(ListBox1.Items.Count, "AAA") '3- add AAA midle: ListBox1.Items.Insert(ListBox1.Items.Count / 2, "AAA") '4- add AAA 2nd position: ListBox1.Items.Insert(1, "AAA") '5- add specific name first: Dim s As String s = InputBox(" enter the name") ListBox1.Items.Insert(0, s) '6- add specific name last: Dim s As String s = InputBox(" enter the name") ListBox1.Items.Insert(ListBox1.Items.Count, s)

56. List box operations and codes '7- add specific name midle: Dim s As String s = InputBox(" enter the name") ListBox1.Items.Insert(ListBox1.Items.Coun t / 2, s) '8- add specific name 4th position: Dim s As String s = InputBox(" enter the name") ListBox1.Items.Insert(3, s) '9- add AAA in specific location by user: Dim x As Integer x = InputBox(" enter location") ListBox1.Items.Insert(x, "AAA") '10- add specific name in specific location by user: Dim s As String s = InputBox(" enter the name") Dim x As Integer x = InputBox(" enter location") ListBox1.Items.Insert(x, s)

List box operations and codes '11- delete first: ListBox1.Items.RemoveAt(0) '12- delete last: ListBox1.Items.RemoveAt(ListBox1.Items.Count - 1) '13- delete middle: ListBox1.Items.RemoveAt((ListBox1.Items.Count - 1) / 2) '14- delete 3rd position: ListBox1.Items.RemoveAt(2) '15- delete bu specific location: Dim x As Integer x = InputBox(" enter position to delete ") ListBox1.Items.RemoveAt(x)

58. List box operations and codes '16- delete be selection: ListBox1.Items.Remove(ListBox1.SelectedI tem) '17- clear items: ListBox1.Items.Clear() '18- is empty: If ListBox1.Items.Count = 0 Then MsgBox("empty list") Else MsgBox(" NOT Empty list") End If '19- search by name: Dim i As Integer Dim s As String s = InputBox(" enter name to find") Dim x As Integer For i = 0 To ListBox1.Items.Count - 1 Step 1 If ListBox1.Items.Item(i) = s Then MsgBox(" found") End If Next '20- count list elements: MsgBox(ListBox1.Items.Count)

RANDOM NUMBER BETWEEN A AND B, WHERE A IS THE HIGHER BOUNDARY, AND B IS THE LOWER BOUNDARY WITH IS ( B + INT ( RAND ( ) * A – B). FOR MOVING ELEMENTS, THE LEFT AND TOP PROPERTIES ARE USED, WHILE THE HEIGHT AND WIDTH PROPERTIES USED FOR CHANGING THE SIZE.

80. Create new project from vb.net Then chose the programming language ( visual basic, c#, asp, J#), which is visual basic. Then chose project type( web, windows application, smart device), which is smart device. Then chose the device type ( pocket pc, smart phone, windows),which is windows. Then chose the environment (device application ), As shown in figure

81. The form will appears as shown in the following figure, which is the same as normal windows application you used to work with, with almost all components (tools ).

82. Then we will write the code for each button as shown in the figure below.

83. For programming smart phone, we will design the form and after that will write the code for each component as follows. We will design two buttons for changing the background of the smart device, as shown below.

84. After that we will run the program by choosing bone of the emulators that suitable for or device( simulator) as shown in the following figure.

85. SMART DEVICE After running the program windows simulate the smart device will appears and allow user to deal with it. For installing the application in smart device, connect the device with the computer And save the application in the smart device The application will auto matic ly save in programs file and will started when you run it from the device.
