In Objective-c we create range by using NSRange NSRange range; So how to create range in Swift? Updated for Swift 4 Swift ranges are more complex than NSRange , and they didn't get any easier in Swift 3. If you want to try to understand the reasoning behind some of this complexity, read this and this . I'll just show you how to create them and when you might use them. Closed Ranges: a...b This range operator creates a Swift range which includes both element a and element b , even if b is the maximum possible value for a type (like Int.max ). There are two different types of closed ranges:

Checking a number range with regular expressions

霸气de小男生 提交于 2019-11-27 05:49:33
问题 I'm using a regular expression to validate a certain format in a string. This string will become a rule for a game. Example: "DX 3" is OK according to the rule, but "DX 14" could be OK too... I know how to look at the string and find one or more "numbers", so the problem is that the regex will match 34 too, and this number is out of "range" for the rule... Am I missing something about the regex to do this? Or is this not possible at all? 回答1: Unfortunately there's no easy way to define ranges

Google App Engine - list of IP addresses?

隐身守侯 提交于 2019-11-27 05:42:58
问题 I know that Google App Engine does not support an application having a static IP address, but I'd like to know if there is a list or range of IP addresses that an app could potentially have? I'd like to use that list as a whitelist of IP addresses for another application deployed elsewhere. 回答1: In addition to the other answers, GAE premier support directed me to this name, esp as the source IP address for URLFetch calls: $ dig -t txt _cloud-netblocks.googleusercontent.com which answers:

VBA: Modify chart data range

╄→гoц情女王★ 提交于 2019-11-27 05:20:55
My "Chart data range" is ='sheet1'!$A$1:$Z$10 . I'd like to make a VBA macro (or if anybody knows a formula I can use, but I couldn't figure one out) to increase the ending column of the range for chart1 by 1 every time I run the macro. So essentially: chart1.endCol = chart1.endCol + 1 What is the syntax for this using ActiveChart or is there a better way? Netloh Assuming that you want to expand the range (by adding one extra column) to add one more observation for each series in you diagram (and not to add a new series), you could use this code: Sub ChangeChartRange() Dim i As Integer, r As

Drag the Range of a UI Input Range Slider

问题 <---------[]=====================================[]--------> 0 10 90 100 I need an input range slider with two handles to select a range, and the ability to drag the range (the equals signs in the above diagram). So, in the above example, start=10 and end=90, and it is dragged left by shifting the entire line between the two handles: <[]=====================================[]------------------> 0 80 100 Now Start is 0 and End is 80, accomplished without dragging the handles.

Date range in date range

Actually this task seemed very easy to me, but i got a little bit stuck and would be thankful for some hints :D I have some events with a start and an end time - and i would like to create a table with calendar weeks. Therefore i wrote a method to to check if an event is within this week to color it like this: private boolean inWeek(Date date, Entry pe) { return ((pe.getStartsAt().after(Util.firstDayOfWeek(date)) || pe.getStartsAt().equals(Util.firstDayOfWeek(date))) && (pe.getEndsAt().before(Util.lastDayOfWeek(date)) || pe.getEndsAt().equals(Util.lastDayOfWeek(date)))); } This case was okay

Can I hint the optimizer by giving the range of an integer?

 ̄綄美尐妖づ 提交于 2019-11-27 04:56:34
问题 I am using an int type to store a value. By the semantics of the program, the value always varies in a very small range (0 - 36), and int (not a char ) is used only because of the CPU efficiency. It seems like many special arithmetical optimizations can be performed on such a small range of integers. Many function calls on those integers might be optimized into a small set of "magical" operations, and some functions may even be optimized into table look-ups. So, is it possible to tell the

How to check if the current time is in range in python?

泄露秘密 提交于 2019-11-27 04:48:20
I need to check if the current time is in timerange. The most simple case time_end > time_start: if time(6,0) <= now.time() <= time(12,00): print '1' But troubles begin when user enters a time range when the end time is smaller than the start time, e.g. "23:00 - 06:00". A time like '00:00' will be in this range. About 5 years ago I wrote this PHP function: function checkInterval($start, $end) { $dt = date("H:i:s"); $tstart = explode(":", $start); $tend = explode(":", $end); $tnow = explode(":", $dt); if (!$tstart[2]) $tstart[2] = 0; if (!$tend[2]) $tend[2] = 0; $tstart = $tstart[0]*60*60 +

Excel VBA: Range to String Array in 1 step

假如想象 提交于 2019-11-27 04:48:16
I know you can easily take a range of cells and slap them into a Variant Array but I want to work with a string array (because it's single-dimensional and takes less memory than a Variant array). Is there any way to automatically convert a range into a string array? Right now I am using a function that will take the range and save the values in a variant array, then convert the variant array to a string array. It works nice , but I'm looking for a way to go directly from the range to string array. Any help would be greatly appreciated. Function RangeToArray(ByVal my_range As Range) As String()

Combined total for multiple jQuery-UI Sliders

末鹿安然 提交于 2019-11-27 04:41:02
I'm trying to implement a page where there are 4 jQuery-UI sliders, and I want to make it so the combined total of all 4 sliders will never go over 400. I don't mind which way this is implemented, it can be from a 0 start, and as soon as you change 1 slider, the remaining available total decreases or setting a slider past the maximum, decreases the values on the other sliders. P.S. The sliders go in increments of 10. All ideas & suggestions are welcome, and I've set up a jsFiddle if you'd like to test. Well here ya go: var sliders = $("#sliders .slider"); sliders.each(function() { var value =
