运行效果：
程序代码： Dim myarray(10) As String '定义全局变量，文字数组 Dim i As Integer
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer) If KeyCode = 37 Then '键盘按键左边← Call Image1_Click ElseIf KeyCode = 39 Then '键盘按键右边→ Call Image2_Click End If End Sub
Private Sub Form_Load() '定义文字数组，初始化timer控件、索引值i Timer1.Enabled = fasle Timer1.Interval = 100 myarray(0) = "大": myarray(1) = "小": myarray(2) = "多": myarray(3) = "少" myarray(4) = "前": myarray(5) = "后": myarray(6) = "左": myarray(7) = "右" myarray(8) = "中": myarray(9) = "上": myarray(10) = "下" Label1.Left = -3800 i = -1 Call Image2_Click End Sub
Private Sub Image1_Click() '移动到上一个字 If i > 0 Then i = i - 1 Label1 = myarray(i) End If Timer1.Enabled = True Label1.Left = -4000 End Sub
Private Sub Image2_Click() '移动到下一个字 If i < 10 Then i = i + 1 Label1 = myarray(i) End If Timer1.Enabled = True Label1.Left = -4000 End Sub
Private Sub Image2_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) Image1.MousePointer = 99 Image1.MouseIcon = LoadPicture("c:\windows\cursors\harrow.cur") End Sub
Private Sub Image3_Click() Me.WindowState = vbMinimized '最小化窗口，需要把showintaskbar属性设置为true End Sub
Private Sub Image3_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) Image3.MousePointer = 99 Image3.MouseIcon = LoadPicture("c:\windows\cursors\harrow.cur") End Sub
Private Sub Image4_Click() End End Sub
Private Sub Image4_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) Image4.MousePointer = 99 Image4.MouseIcon = LoadPicture("c:\windows\cursors\harrow.cur") End Sub
'Timer控件实现文字移动效果，如果移动到中间位置就停止。 Private Sub Timer1_Timer() If Label1.Left < 5000 Then Label1.Left = Label1.Left + 200 Else Label1.Left = -4000 End If If Label1.Left > 1560 And Label1.Left < 1660 Then Timer1.Enabled = False End If End Sub
学习总结： 1、harrow.cur为windowsXP的系统图标，windows7中没有，要在win7中运行则需要修改成其他图标，否则报错。 2、方向键的键盘码keycode如下： keycode 37 = Left ← keycode 38 = Up ↑
keycode 39 = Right →
keycode 40 = Down ↓
3、如果使用if...else语句，else遵循就近原则。
