This means that you should try to reduce the number of times you pass data between VBA and Excel. This is where ranges are useful. Instead of reading and writing to each cell individually in a loop, read the en
首先来对比一下通用的查找算法和字符串查找算法： 各种字符串查找算法的性能特点 算法（数据结构）优点 ...
2.1 使用Array函数创建数组 Dim arr(1 To 3) As Variant arr = Array(0, 1, 2) '创建了一个包含3个整数的一维数组 2.2 通过单元格区域创建数组 Dim arr As Variant arr = Range("A1:B3").Value '将把A1:B3的数据存储到数组arr中 2.3 使用For循环创建数组 Dim arr(1 To 3) As Integer Dim i As...
Returns a value or the reference to a value from within a table or range. There are two forms of theIndexfunction: the array form and the reference form. (1)数组形式:INDEX(array,row_num,column_num)返回数组中指定的单元格或单元格数组的数值。 Use the array form if the first argument toI...
CopyFromRecordset 方法:将 ADO 或 DAO Recordset 对象的内容复制到工作表中(从指定区域的左上角开始)。 如果 Recordset 对象包含具有 OLE 对象的字段,则该方法无效。 CopyPicture 方法:将所选对象作为图片复制到剪贴板。 Range.CreateNames 方法:在指定区域中依据工作表中的文本标签创建名称。

So, you may be wondering how to do this with a dynamic array. Thankfully, there are the LBound and UBound functions in Excel VBA for this task. In the following code, the array is populated with the values from range B2:B13, just as in a previous example. However, the LBound and ...
Dim arr()arr = Sheet1.UsedRange.Value '已使用区域，不确定大小arr = Sheet1.Range("A1").CurrentRegion 'A1单元格所在的数据区域arr = Sheet1.Range("A1:F5").Value '限定大小arr = Sheet1.Range("A1").Resize(5, 6)通过循环读取下标，给数组的每个元素赋值，如我们的示例代码：For i = 1...
This is the code from the video: Option Explicit Sub TestMe() Dim myArr2D, myArr1Row, myArr1Col As Variant Dim myRange2D As Range, myRange1Row As Range, myRange1Col As Range Set myRange2D = ThisWorkbook.Worksheets("Sheet1").Range("A1:C20") Set myRange1Row = ThisWorkbook.Workshee...
It first declares an array named Myarray with the data type Variant. Then, it sets the dimension of the array to be equal to the number of rows in the range B4:B13. If you have to convert any other range, enter it here. Or you can use an Input Box to take the range from the...
