为程序错误设置Description属性的最好方法是在Raise方法中设置Description参数值,例如代码: Sub TestErrDes() On Error GoTo errH Err.Raise Number:=65300, _ Description:="发生用户输入错误" Done: Exit Sub errH: MsgBox Err.Description End Sub 运行代...
Sub For_Loop_Step_Size_Error() On Error Resume Next K = 1 / 0 ' Line causing error due to a number being divided by zero If Err.Number <> 0 Then MsgBox "The error number is: " & Err.Number K = 2 ' Some arbitrary value of K for any exception in the code. End If y = 1...
然后,使用On Error Resume Next语句来延迟错误捕获,以便确定下一语句生成的错误的上下文。 请注意,Err.Clear用于在处理错误后清除Err对象的属性。 VB SubOnErrorStatementDemo()OnErrorGoToErrorHandler' Enable error-handling routine.Open"TESTFILE"ForOutputAs#1 ' Open file for output. Kill "TESTFILE" ' Attem...
Here, the ‘On Error Resume Next’ line forces the code to continue, even if an error is detected. We then use the If Err > 0 test to create a warning message, only if the error exists. The ‘On Error Goto 0’ resets VBA to its default state. Example 2 Here, the code is calcu...

Private Function testFor() Dim i For i = 11 To 10 Debug.Print i Next i End Function 每次内部代码执行结束后,循环变量会增加一个 步长值 并重复之前的检查操作直到检查结果为假,退出循环。步长值可以为正为负也可以为0。 了解循环基本原理之后我们来改写1.4.2 例子。打印出前6个数 Private Function tes...

For Each kValue In dict.keys Debug.Print kValue, vbTab, dict(kValue) Next kValue End Sub 运行结果如下图1所示。 图1 如果设置了早期绑定,那么还可以使用For循环来遍历字典元素,例如: Sub testForEachLoop() Dim dict As New Dictionary
