效果: 源码: Sub 判断文件是否存在() Dim strcfg As String strcfg = "D:\a.cfg" If Dir(strcfg, vbDirectory) = "" Then MsgBox "错误:配置文件不存在!" & Chr(10) & strcfg 'Chr(10)换行符 Exit Sub End If End Sub
语句一:if判断语句 Sub 判断1() '单条件判断 If Range("a1").Value > 0 Then Range("b1") = "正数" Else Range("b1") = "负数或0" End If End Sub Sub 判断2() '多条件判断 If Range("a1").Value > 0 Then Range("b1") =
方法1. 用VBA自带的dir()判断,代码如下: 在 Microsoft Windows 中, Dir 支持多字符 (*)和单字符 (?) 的通配符来指定多重文件 Function IsFileExists(ByVal strFileName As String) As Boolean ) <> Empty Then IsFileExists = True Else IsFileExists = False End If End Function Sub Run() If IsFileExi
通过输入月份,判断是否是闰年 [代码区域] Sub 判断闰年() Dim year As Integer '用于保存输入的年份 year = CInt(InputBox("请输入需要判断的年份:", "判断闰年")) '输入年份 = <> Then MsgBox "" & "是一个闰年", vbOKOnly, "判断闰年" Else = = Then MsgBox ""
1.判断列内是否有重复值: Dim arrT As Range Dim rng As Range Set arrT = Range("A:A")'判读A列单元格 For Each rng In arrT If rng = Empty Then'如果单元格为空就退出循环,否者循环65535次 Exit For End If k = Application.CountIf(arrT, rng)’用CountIf函数扫描出重复值,跟excel的CountIF函数一样 If k > 1
判断语句 大部分和 Lua 差不多,多了一个 Switch 语句 循环 For 循环 多次执行一系列语句,缩写管理循环变量的代码. For i = start To end [Step X]...Next Private Sub Constant_demo_Click() Dim a As Integer a = 10 For i = 0 To a Step 2 MsgBox ("The value is i is : " & i) Next End Sub For Each
判断是否为空: Sub 测试() If IsEmpty(Range("A100000")) Then Debug.Print "空的" End If End Sub 或者 Sub 测试() If Range("A100000").Value = "" Then Debug.Print "空的" End If End Sub 判断是否是数字:(注意空的也会判断为数字) Sub 测试() If IsNumeri
Function ISFORMULA(ByVal rg As Object) As Variant Dim temp As Variant Dim i As Integer, j As Integer temp = rg.Formula If IsArray(temp) Then For i = 1 To UBound(temp, 1) For j = 1 To UBound(temp, 2)
VBA 格式化字符串 VBA 的 Format 函数与工作表函数 TEXT 用法基本相同,但功能更加强大,许多格式只能用于VBA 的 Format 函数,而不能用于工作表函数 TEXT ,以下是本人归纳的几点用法,希望对学习VBA有所裨益.Format(值,格式(可选参数))一.数字格式:1.General Number:普通数字,可以用来去掉千位分隔号和无效 0 .如:Format("1,234,567.80", "General Number")="1

今天项目组的一个同事问我如何快速的找到一个Excel中第3列和第5列的值完全重复的值,我想了想虽然Excel中自带查找重复值的功能,但是好像只能对同一列进行比较,所以就写了一个VBA进行处理,VBA非常简单,但效果不错. Sub FindDuplicatesInColumn() Dim lastRow As Long Dim matchFoundIndex As Long Dim iCntr As Long lastRow = ' 初始化临时列, 第7列用来存放结果,第8列将3 5两列的值拼接起
