range

问题 I'm trying to copy multiple non-adjacent (non-contiguous) excel columns to an array but it's not working. Below is what I've tried... Public Function Test() Dim sh As Worksheet: Set sh = Application.Sheets("MyWorksheet") Dim lr As Long: lr = sh.Cells(sh.Rows.Count, 1).End(xlUp).row Dim r1 As Range: Set r1 = sh.Range("A1:A" & lr) Dim r2 As Range: Set r2 = sh.Range("C1:C" & lr) Dim rAll As Range: Set rAll = Union(r1, r2) 'Dim arr() As Variant: arr = Application.Transpose(rAll) <-- Throws Type

问题 I am familiar with the Enumerable.Range method for generating an enumeration of values. But I would like something slightly different. I want to provide a min value, max value, and a number of desired points. IE: Method(double min, double max, int numberOfSteps) taking Method(0, 1000, 11); would return 0, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 I figure for something like this, there must be a built-in method but my search hasn't turned anything up. Am I missing something? 回答1:

问题 I am using the range() function to create an array. However, I want the keys to be the same as the value . This is ok when i do range(0, 10) as the index starts from 0 , however if i do range(1, 11) , the index will still start from 0 , so it ends up 0=>1 when i want it to be 1=>1 How can I use range() to create an array where the key is the same as the value ? 回答1: How about array_combine? $b = array_combine(range(1,10), range(1,10)); 回答2: Or you did it this way: $b = array_slice(range(0,10)

问题 list1 = [1, 2, 3, 4] i'm trying to figure out a way to change the step value for each printed i What I've tried r = 0 for i in range(0, 10, list1[r]): print i r = r + 1 回答1: I would suggest implementing a generator of your own for this using while loop. Example - def varied_step_range(start,stop,stepiter): step = iter(stepiter) while start < stop: yield start start += next(step) Then you can use this as - for i in varied_step_range(start,stop,steplist): #Do your logic. We do the step = iter

问题 My purpose is to display pdf use pdf.js in lazy mode,I have two choice: Use disableRange=false It worked fine when use a url in nginx,but when I use a java sevlet url: /dowload/fileid/123，it doesn't load via 206 partial content (range requests) but 200 and then viewed in the viewer. public void download(String identNo,HttpServletRequest request,HttpServletResponse response) { File file = getFileFromServer(identNo); BufferedInputStream bis = null; OutputStream os = null; BufferedOutputStream

问题 I wanted to copy some not continous ranges from several workbook/ worksheets to a specific sheet. I am using a userform and RefEdit control on that.
