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 entire range into an array at the start, loop through the array, and then wr...
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...
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...
使用 Union (range1, range2, ...) 可返回多区域范围,即返回由两个或多个连续单元格区域构成的范围。 Union(Range("A1:B6"),Range("D5:H9")) 表示由A1:B6和D5:H9构成的范围 Range对象方法 Activate 方法:激活单个单元格,该单元格必须处于当前选定区域内。 若要选择单元格区域, 请使用select方法。 AddC...

InputArr.Copy -> Using the command Copy to copy the input array range from the worksheet. PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=True -> Using the PasteSpecial function on the result variable ResultArr to save the transposed values in the target rang...
SubCopyFileCellsValue()FileCopy ActiveSheet.Range("C2"),ActiveSheet.Range("C4")End Sub 示例4:复制前检查文件是否存在 FileCopy将覆盖文件而不会显示任何错误,因此在复制前检查文件是否已经存在很有必要。 下面的代码检查复制文件的目标位置中文件是否已存在,如果存在则弹出消息框来供选择。
