  1. Algorithms Programming – step by step instructions to a computer

  2. Controls

  3. Events

  4. Variables Integer Double (floating pt.) Char String Boolean

  5. User Input Input into a TextBox: TextBox1.Text … contains a String, or a number Click on a Button Private Sub Command1_Click() …put code here to handle clicks End Sub

  6. User Output A MsgBox Private Sub Command1_Click() MsgBox ("Hello") End Sub

  7. Iteration 1 Integer X = 0 While X < 1000 … do something X = X+1 Wend

  8. Iteration 2 For X = 1 to 1000 … do something Next X

  9. Conditionals if ( X > 10 ) then Y = 0 else if (X < 5) Y = 10000000 else Y = 12 End if
