Introduction to VBA Array Arrays are powerful tools for managing data, and they allow you to group related values under a single variable name. Here are the four types of string arrays you can work with in VBA: Type 1 – Declare Static String Array If you want an array that can store ...
Function Pxy(arr(), FieldName As String, Optional arrType As Integer = 0)Dim k$, t$ k = 0 t = 0 Select Case arrType Case Is = 0 For i = LBound(arr) To UBound(arr) k = k + 1 If arr(i) = FieldName Then t = 1 Exit For End If Next...
MyArrayPtr(ByRef v As Variant) As Long Dim b(16 - 1) As Byte CopyMemory VarPtr(b(0)), VarPtr(v), 16 Printf "b = 0x% x", b Dim ptr As Long CopyMemory VarPtr(ptr), VarPtr(b(8)), 4 ' - 0x20 8-11存的是数组地址 ' - 0x60 8-11存的是数组地址的地址 If b(1) = &...
'dic.items:字典的值;.cells(1,1).resize(1,dic.count)=dic.items '判断某内容是否存在与字典的键中ifdic.exists("内容")then debug.print"字符串‘内容’存在于字典的键中"'清空字典,有时候其他过程也需要使用字典,当前过程已经使用完了,但我们又不想重新创建字典对象,这时候我们可以public字典全局变量,再清...

Sub MultiDimensionalArray() Dim Arr(1 To 3, 1 To 3) As String Arr(1, 1) = 5 Arr(2, 1) = 10 Arr(3, 1) = 15 Arr(1, 2) = 6 Arr(2, 2) = 12 Arr(3, 2) = 18 End Sub Based on Size Case 1 – Static Array The default array size starts from 0. If an array with ...
Dim str As String Dim rng As Range Dim i As Long str = "所选区域的段落数:"& _ Selection.Paragraphs.Count & _ vbCrLf & vbCrLf & _ "所选区域的句子数:" & _ Selection.Sentences.Count & _ vbCrLf & _ "句子分别是:" & vbCrLf
If StrComp(sString1,sString2,vbTextCompare)=-1 Then 在性能上要提高30%,且更容易阅读和理解。 2.2 转换字符串 2.2.1 StrConv函数 使用StrConv函数来按指定类型转换字符串。其语法为: StrConv(string,conversion,LCID) 其中,参数string为要转换的字符串,参数conversion为指定转换的类型,参数LCID为可选参数。
