string-formatting

问题 What is a culture-invariant way of constructing a string such that the Javascript Date() constructor can parse it and create the proper date object? I have tried these format strings which don't work (using C# to generate the strings): clientDate.ToString(); // gives: "11/05/2009 17:35:23 +00:00" clientDate.ToString("MMM' 'dd', 'yyyy' 'h':'mm':'ss' 'tt"); // works on an English server // but on a French server, gives: "mai 11, 2009 5:35:23" // Javascript won't parse that. clientDate.ToString(

问题 I have a TimeSpan representing the amount of time a client has been connected to my server. I want to display that TimeSpan to the user. But I don't want to be overly verbose to displaying that information (ex: 2hr 3min 32.2345sec = too detailed!) For example: If the connection time is... > 0 seconds and < 1 minute -----> 0 Seconds > 1 minute and < 1 hour -----> 0 Minutes, 0 Seconds > 1 hour and < 1 day -----> 0 Hours, 0 Minutes > 1 day -----> 0 Days, 0 Hours And of course, in cases where the

问题 I am grabbing some data from an Excel sheet and populating it into a Word template. I'm hoping that I can assign some of the Document's character styles to sub strings that will be added to the Document as the string is built up rather than having add the string to the Document and then select each string individually to apply the appropriate style. Right now, I'm concatenating a few strings and adding them to a text box in the document like this: ActiveDocument.Shapes("Text Box 7").TextFrame

问题 I'm currently writing a report in PHP that occasionally has to display negative currency amounts. Said currency amounts are stored in the database like "-44.00". Ideally this number would be output as "($44.00)" on the report. I know I can write some semi-complicated function to detect whether the number is negative and manually insert the parenthesis, but I was wondering if there was some handy PHP function that can do this for me before I re-invent the wheel. I've searched around and have

问题 Using .NET string formatting you can plug the same value into a format string multiple times: Console.Write("{0}{0}{0}", 1) //prints "111" Is there any way to do this with printf-style formatting, supplying the value only once? 回答1: No. The values are taken in order, from the stack, when passed to the function. If you want multiple appearances of the same value if different parts of the string, you have to supply them in order, multiple times. Think of it this way: you have a string, with

问题 This is one of my DataGridTextColumn controls looks like : <DataGridTextColumn x:Name="contractStartDateColumn" Header="Start Date" Binding="{Binding Path=StartDate, StringFormat={}\{0:dd/MM/yyyy\}}" /> Then how can I set StringFormat={}{0:dd/MM/yyyy} to all of DataGridTextColumn controls instead of setting every single one ? 回答1: You can create custom binding class that sets StringFormat and use it to bind values: public class CustomBinding : Binding { public CustomBinding(string path) :

问题 I am using CultureInfo methods to successfully format all different currencies into their correct format. But on some exceptions, such as EUR and SEK currencies I need to be able to add them after the value. At the moment my CultureInfo is formatting them in the following way: "SEK 1.00,00" when it needs to be "1.00,00 SEK". Any help is appreciated. 回答1: All you need is to change the NumberFormatInfo.CurrencyPositivePattern and NumberFormatInfo.CurrencyNegativePattern properties for the
