 Title Bar  Menu Bar  Tool Bars  Solution Explorer  Properties Window  ToolBox  Auto Hide ... 14

 Form - Window  Text  Size  FormBorderStyle  StartPosition  WindowState ... 15

 Properties  Events  Alphabetical  Categorized 16

TextBox Get Input Display Output Label Display Information / Output Button User action... 18

 The button’s Click Event Users click a button when they want to do something.  Event Procedure VB function that will be called when the event happens  We will write the event procedure  Click Event procedure template Double click the button 19

Dim theName As String theName = txtName.Text ‘ This is comment ‘ To remove spaces from both ends theName = txtName.Text.Trim() We should get variable values from controls at the beginning, then use the variables, not the controls, in the code. 20

 Method Show MessageBox.Show(“Please Enter Your Name”)  Caption (Title), MessageBoxButtons and MessageBoxIcon MessageBox.Show("Enter Your Name Please!", _ "Lab 1", MessageBoxButtons.OK, _ MessageBoxIcon.Exclamation)  Line continuation char: “ _” VB has NO statement terminator 21

‘ Operators “&” and “+” append strings MessageBox.Show("Hello, " & theName + "!”) MessageBox.Show("Hello, " & theName + "!", "Lab 1”, _ MessageBoxButtons.OK, _ MessageBoxIcon.Information) 22

If Statement If theName = "" Then MessageBox.Show("Enter Your Name Please!", "Lab 1", _ MessageBoxButtons.OK, _ MessageBoxIcon.Exclamation) Else MessageBox.Show("Hello, " & theName + "!", "Lab 1", _ MessageBoxButtons.OK, _ MessageBoxIcon.Information) End If 23

The Click Event Procedure Pseudo Code Private Sub btnHello_Click(...) Handles btnHello.Click ‘ Declare variable(s) ‘ Get input ‘ If empty input ‘ Display a message ‘ Else ‘ Display a different message End Sub 24

The Click Event Procedure Private Sub btnHello_Click(...) Handles btnHello.Click Dim theName As String theName = txtName.Text.Trim() If theName = "" Then MessageBox.Show("Enter Your Name Please!", "Lab 1", _ MessageBoxButtons.OK, _ MessageBoxIcon.Exclamation) Else MessageBox.Show("Hello, " & theName + "!", "Lab 1", _ MessageBoxButtons.OK, _ MessageBoxIcon.Information) End If End Sub 25
