flutter timeofday calculations

由 孤街醉人 提交于 2019-12-24 05:46:13
问题 in my flutter app the user picks a time and I need to simply add some hours and minute to it to display the result. Is that easily possible? Unfortunately, there doesn't seem to be a function like TimeOfDay.add(). Any ideas? Thanks! 回答1: You can Use Date Time for that: You can add Minutes or Hours as you like. TimeOfDay.fromDateTime(DateTime.now().add(Duration(hours: 2))); // result is 2hrs ahead of current time 来源： https://stackoverflow.com/questions/53015124/flutter-timeofday-calculations

Programmatically creating worksheets in an Excel Add In (C#)

由 懵懂的女人 提交于 2019-12-24 00:54:24
问题 According to MSDN, one can programmatically create and delete Excel Worksheets in Visual Studio (http://msdn.microsoft.com/en-us/library/6fczc37s.aspx).

The user is supposed to be able to press it and create a new worksheet, but it doesn't work. So I decided

eclipse cdt add multiple libraries

由 末鹿安然 提交于 2019-12-23 19:41:22
问题 Is there any way to add multiple libraries or only one by one in C/C++ Build --> Settings --> MinGW C++ Linker --> Libraries (-l) ? What I mean is there a way just to copy from somewhere (some txt file for example) all of the names of libraries and then to paste them into the Libraries (-l) field, the same way it could be done in Visual Studio 2010? Also, where does eclipse stores information about this? I have to rename a lot of libraries (from opencv245 to opencv246) so I guess if it is

Cannot add two numbers correctly without using parseFloat in JavaScript

由 佐手、 提交于 2019-12-23 19:35:47
问题 I came across this problem. It adding numbers using parseFloat or parseInt.

由 瘦欲@ 提交于 2019-12-23 17:28:05
问题 In Python is there a simple way of adding the individual numbers of lists to the individual numbers of other lists? In my code I need to add about 10 long lists in a similar fashion to this: listOne = [1,5,3,2,7] listTwo = [6,2,4,8,5] listThree = [3,2,9,1,1] Therefore I want the result to be: listSum = [10,9,16,11,13] Thanks in advance 回答1: Using zip, sum and list comprehension: >>> lists = (listOne, listTwo, listThree) >>> [sum(values) for values in zip(*lists)] [10, 9, 16, 11, 13] 回答2:
