代码1：程序终止及退出方法

1 Option Explicit 2 3 '一、END语句 4 5 '作用：强制退出所有正在运行的程序。 6 7 '二、Exit语句 8 9 '退出指定的语句 10 11 '1、Exit Sub 12 Sub e1() 13 Dim x As Integer 14 For x = 1 To 100 15 Cells(1, 1) = x 16 If x = 5 Then 17 Exit Sub 18 End If 19 Next x 20 Range("b1") = 100 21 End Sub 22 '2、Exit function 23 Function ff() 24 Dim x As Integer 25 For x = 1 To 100 26 If x = 5 Then 27 Exit Function 28 End If 29 Next x 30 ff = 100 31 End Function 32 33 '3、Exit for 34 Sub e2() 35 36 Dim x As Integer 37 For x = 1 To 100 38 Cells(1, 1) = x 39 If x = 5 Then 40 Exit For 41 End If 42 Next x 43 44 Range("b1") = 100 45 End Sub 46 '4、Exit do 47 Sub e3() 48 Dim x As Integer 49 Do 50 x = x + 1 51 Cells(1, 1) = x 52 If x = 5 Then 53 Exit Do 54 End If 55 Loop Until x = 100 56 Range("b1") = 100 57 End Sub

代码2：分支及跳转方法

1 Option Explicit 2 3 'Goto语句,跳转到指定的地方 4 5 Sub t1() 6 Dim x As Integer 7 Dim sr 8 100: 9 sr = Application.InputBox("请输入数字", "输入提示") 10 If Len(sr) = 0 Or Len(sr) = 5 Then GoTo 100 11 12 End Sub 13 14 'gosub..return ,跳过去,再跳回来 15 16 Sub t2() 17 Dim x As Integer 18 For x = 1 To 10 19 If Cells(x, 1) Mod 2 = 0 Then GoSub 100 20 Next x 21 Exit Sub 22 100: 23 Cells(x, 1) = "偶数" 24 Return '跳到gosub 100 这一句 25 End Sub 26 27 'on error resume next '遇到错误,跳过继续执行下一句 28 29 Sub t3() 30 On Error Resume Next 31 Dim x As Integer 32 For x = 1 To 10 33 Cells(x, 3) = Cells(x, 2) * Cells(x, 1) 34 Next x 35 End Sub 36 37 'on error goto '出错时跳到指定的行数 38 39 Sub t4() 40 On Error GoTo 100 41 Dim x As Integer 42 For x = 1 To 10 43 Cells(x, 3) = Cells(x, 2) * Cells(x, 1) 44 Next x 45 Exit Sub 46 100: 47 MsgBox "在第" & x & "行出错了" 48 End Sub 49 50 'on error goto 0 '取消错误跳转 51 52 Sub t5() 53 On Error Resume Next 54 Dim x As Integer 55 For x = 1 To 10 56 If x > 5 Then On Error GoTo 0 57 Cells(x, 3) = Cells(x, 2) * Cells(x, 1) 58 Next x 59 Exit Sub 60 61 End Sub

代码3 实现定时执行

Sub runing_when_open() Dim newtime As Date newtime = Now + TimeValue("00:01:00") 'newtime为1分钟后 Call over_time '1分钟后调用自身 Application.OnTime newtime, "runing_when_open" End Sub
