formatting

问题 I'm using Nlog to write some logging to a textfile. Partial nlog.config: <target name="file" xsi:type="File" fileName="${basedir}/MBWRunner_log.txt" layout="${date} (${level}): ${message} Exception: ${exception:format=Method, ToString}"/> Lines in the logfile look like this: 0001-01-01 00:00:00 (Trace): MBWRunner started As you can see the date and time are all 0. I have tested {longdate} and {date:format=yyyyMMddHHmmss} with the same result. The application is a console app, run from an

问题 Is it possible to setup some form of conditional formatting of textblock controls in XAML so that the color of the text can be changed depending on the text (eg. Text = "good" then set to green, Text = "bad" then set text to red.) I have tried some examples but they don't seem to work, presumably because WP8 works differently. 回答1: One simple way is in the view with DataTrigger s like: Namespaces: xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:ei="http://schemas

问题 I am making an Rmarkdown document that knits to an HTML page. Instead of separating some text sections with headers or bullets, I just want to draw horizontal lines between them. According to http://rmarkdown.rstudio.com/authoring_basics.html this would be called a "horizontal rule" and I can do that with three or more --- . However when I actually try to do this, various sections disappear from the html doc. Here is a very simple example of my code: --- title: "formatting issue" author: "rrr

问题 Scenario: I am calling a function that returns a field that the user enters in. The field usually returns a number like '120000' which I then use to_char to convert into '120,000'. Problem: Some users enter in values such as '120,000' which gives me an error when trying to use to_char. Also the function will return a space ' ' if no value is found. I tried something with to_number earlier and it has a problem with the ' ' I believe. Question: What would be the best way to handle this problem?

问题 I have a hybrid ASP.Net web forms/MVC app. On one of the MVC "pages"/views, I have it render a bunch of dates using the ToShortDateString() and ToLongDateString(). These work correctly most of the time, but the first time I load the view after compiling the app, they are formatted incorrectly. I traced this down and checked the current thread's culture. For 99% of the time it's en-US, but on the first load of the MVC view after compiling it is set to en-GB. If I reload the page immediately

问题 I have the following .cpp file: //////////////////////////////////////////////////////////////////////////////// void call_long_function_name(bool) {} void sf(bool) {} int main() { bool test = true; if (test) { call_function_name(test); } if (test) { sf(test); } return 0; } (the slashes delimit 80 characters). Using the following configuration file, clang-format suggests: //////////////////////////////////////////////////////////////////////////////// void call_long_function_name(bool) {}

问题 I'm using this free RegExp Designer which does find and replace. How do I search for all numbers and add thousand separators? Input: <node num='12345678'> Output: <node num='12,345,678'> 回答1: To reformat numbers only in "num" attribute values you can do this: (?<=num='\d+)(?=(?:\d{3})+(?!\d)) But note that this will only work in .NET regexes, which is what RegExp Designer uses. Most regex flavors only allow lookbehinds that match a fixed number of characters. Java regexes allow variable

问题 quick question. Is there a smarter/sleeker way to convert minutes into a more readable format, showing only the most significant digit? I'm using Android Studio's Java. public String MinutesToHumanReadable(Long minutes) { ... } ie 2 mins = "2 mins" 45 mins = "45 mins" 60 mins = ">1 hr" 85 mins = ">1 hr" 120 mins = ">2 hrs" 200 mins = ">3 hrs" 1500 mins = ">1 day" My code is very cumbersome, sloppy, and somewhat unreadable. public String MinutesToHumanReadable(long minutes) { String sReturn =

问题 I'm outputting a Double that can be either (+) or negative (-). If the number is a negative the symbol (-) is included automatically, is there a way to do this for positive numbers as well? The only (horrible) way I can do this is : If MyNumber <= 0 then string.Format("{0:0.00}", MyNumber) Else string.Format("+{0:0.00}", MyNumber) End If 回答1: You can use the section separator in your format: string.Format("{0:+0.00;-0.00}", num); The format before the semi-colon will be used for positive

问题 Intro Im developing PHP in NetBeans IDE 7.2 (Build 201207171143) and I love the formatting to clean up my code in my custom format. At the moment I work in a group with colleagues. Some of my colleagues are used to write single line statement without braces (I think this is bad practice). Examples What my colleagues do: <?php if($stackoverflow == 'Cool') echo 'Stack Overflow is Cool!'; ?> What I want when I format the code. <?php if($stackoverflow == 'Cool') { echo 'Stack Overflow is Cool!';
