• MyArray(5) = 101 :给数组的元素赋值 • Dim Data(10,5) :声明一个二维数组变量 • Data(1,1) = “A001” :给数组元素赋值 • Dim cArr(-11 To 20, 1 To 3) As String :声明一个数组,定义数组索引值的上下界 • Dim dArr() As String :声明动态数组 • ReDim dArr(0 To 5,...
12Array: An array is a group of variables. In Excel VBA, you can refer to a specific variable (element) of an array by using the array name and the index number. 13Function and Sub: In Excel VBA, a function can return a value while a sub cannot. ...

调用Sub或Function过程时,可以按过程定义中出现的顺序按位置提供参数,也可以按名称提供参数,而不考虑位置。 例如,下面的Sub过程采用三个参数。 VB SubPassArgs(strNameAsString, intAgeAsInteger, dteBirthAsDate) Debug.Print strName, intAge, dteBirthEndSub ...

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 ...
1、先用Dim声明,Dim arr()或arr。 2、然后Redim arr(1 to 变量) 即:Redim(重新声明) 变动数组时可以使用变量Dim tempArray() As Integer ReDim tempArray(1 To v1) 2. 使用 ReDim Preserve 声明变动数组时,只能改变最末维的大小。即Redim Preserve arr(1 to k1, 1 to 2) 是错误的。 而应该是...
Instead of using a large number of optional parameters it might be better to use a parameter array instead. This can only be used asthe last argumentin a procedure or function. This keyword cannot be used with ByRef, ByVal or Optional (it is always ByRef). ...
