formatting

问题 I must write a stringToNumber parsing function that can use custom strings for the following: decimal separator ( . for en-US => 3.1415 ) thousands separator ( , for en-US => 1,000,000 ) positive sign ( + for en-US => +5 ) negative sign ( - for en-US => -5 ) Can I assume that these are only one character (which would make the implementation easier) or are there any cultures in which any of these are longer? 来源： https://stackoverflow.com/questions/46538917/are-there-cultures-in-which-the

问题 I have an application with a lot of calls to Decimal.ToString(void). The default format is not what is needed. I could change these calls to one of the other Decimal.ToString overloads, but it would be nicer if I didn't have to. So, is there a way to specify a different format for the Decimal.ToString(void) method so that I don't have to modify any of the calls to this method? Update As the answer below indicates, it is possible to do what I want, but I should not do so as it is not good

问题 For my website, I can't get my side column to extend all the way to the end of the body column without giving it a fixed max height (it's supposed to adjust according to the length of the body, which is altered either by the amount of words/content the body has and/or the wrapping of the body in a smaller screen). Please keep in mind that I have a footer at the bottom that is supposed to take up the entire width of the screen so I can't do something that makes the side column longer than

问题 For example, if I enter 32164578542324236.97325074, this number should be displayed in a TextField like 32,164,578,542,324,236.97325074. I tried to handle this, but unsuccessfully: inputField.textProperty().addListener(new ChangeListener<String>() { @Override public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) { BigDecimal bd = new BigDecimal(newValue); NumberFormat formatter = NumberFormat.getNumberInstance(); inputField.setText(formatter

问题 I am attempting to read a file and set the text of a richTextBox equal to it, but the formatting is disappearing after I do so. The "ENTER"s within the text file itself are not visible in the richTextBox. Here is the code I am using: try { using (StreamReader sr = new StreamReader(directory + filePath)) { while (!sr.EndOfStream) { initialText += sr.ReadLine(); } } } Any help would be greatly appreciated. 回答1: When you use sr.ReadLine() , carriage return is removed from string (because it's

问题 I am binding many controls on my form to an object returned from a method call like so: textBoxMoonBeam.DataBindings.Add(new Binding("Text", pi, "MoonBeam")); Note: "pi" is the name of an instantiation of the PlatypusInfo class. ...but when I am grabbing a dateTime value, which by definition includes the time appended to the date, but I only want to show the date in the control, I've got to eschew the type of binding above and instead do this: textBoxDateAztecsFirstSawElvis.Text = pi

问题 I wish to achieve this sort of output with string formatting: GBP......0.8639......0.8399 I have tried using the following code (i stands for currency and e[0] and e[1] are buy and sell values): "{i:.<10}{e[0]:.^6}{e[1]:.>6}".format(i=i, e=e) but the above code does not align the second number to the right, but it just adds it behind the first number, like this: GBP.......0.86390.8399 How can I correct this? 回答1: As a generalized solution: Use this format string if you want the right column,

问题 I know I can do it as follows: String s = "Hello"; int maxLength = 10; System.out.print(getSpaces((maxLength - s.length()) / 2) + s + getSpaces((maxLength - s.length()) / 2)); But I need to do it in a simple way. According to this page: Printf for Java Specification 3.0 (Section 9. flags): I can center the text using ^ as a flag with printf() like this: String s = "Hello"; int maxLength = 10; System.out.printf("%^" + maxLength + "s", s); But I got this error: Exception in thread "main" java

问题 For our current project we have code formatting rules for java and xml files. Is there some way to configure Eclipse to format drools files (*.drl)? 回答1: As far as I know you can't. The current plugin doesn't format the DRL files. It can be a very good contribution to the project :) Cheers 来源： https://stackoverflow.com/questions/7723078/how-to-automatically-format-drools-files-with-eclipse

问题 Sorry for the weird title but I didn't know how to phrase it any better. I'm trying to populate a column on my DataGridView with a number that has 2 decimal places. To do this I'm using Dim _Size as Double = 1.2345 DataGridView1.Item(0, 0).Value = Format(_Size, "0.00") This populates the data correctly, but when sorting by this column, it treats the item as a string. I found on the net, that if you convert the data being entered to a number type (double, integer etc..), it will then sort it
