symbols

问题 Sorry for asking a stupid question, We are trying to print heart symbol from database to Java XML file. But the same is getting printed as "?" not sure where am I missing. Have tried the char unicode. As a practice I tried it using in main method. Please find the sample java class. public static void main(String[] args) { String t = "\u2665"; String myUnicodeSymbol = "\u05D0"; char hollowHeart = '\u2661'; String hollowDiamond = "\u2662"; String spade = "\u2660"; String club = "\u2663";

问题 I was figuring out a problem where starting the application from GDB results in a symbol lookup error, but starting it from the shell works. It turns out that whenever you start a program from within GDB it will start a new shell and thus override all environment variables I had set before starting GDB (like LD_LIBRARY_PATH ). This is not really the behavior I want. Can someone explain the rationale behind this, or tell me how I can turn this off? 回答1: I am guessing that you unconditionally

问题 My question builds upon this question: Ruby Koan: Constants become symbols. I have the following code: in_ruby_version("mri") do RubyConstant = "What is the sound of one hand clapping?" def test_constants_become_symbols all_symbols = Symbol.all_symbols assert_equal __, all_symbols.include?(__) end end Is the correct answer supposed to be the following? assert_equal true, all_symbols.include?("RubyConstant".to_sym) I know I shouldn't just do this: assert_equal true, all_symbols.include?(

问题 Actually, I want to display the currency symbols of all currency codes and I'm using code like this,but i only get "$" symbols -(void) showCurrenciesList { NSNumberFormatter *numFormatter = [[NSNumberFormatter alloc] init]; [numFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; //[numFormatter setLocale: [NSLocale currentLocale]]; NSMutableArray *aryAllCurrencies = [[NSMutableArray alloc] init]; //NSLocale *locale = [[[NSLocale alloc] initWithLocaleIdentifier: @"en_US"] autorelease];

问题 Applications compiled on iOS are assigned identifiers (UUID's) at compile time. These identifiers may be revealed by the dwarfdump tool. Does anyone know how UUID's are generated and what information may be encoded within them? 回答1: Almost certainly they're generated by the CoreFoundation UUID machinery, which creates them based off of the MAC address of your ethernet card, the timestamp, and some other miscellaneous information. You can generate your own UUIDs by running uuidgen . As for the

问题 I'm trying to generate an .eps figure in gnuplot using set terminal postscript eps enhanced color solid I want to include in my figure a title for a plot containing some star symbols, e.g ★ ☆ I tried through this: plot "./mydata" u 1:2 title "★ ☆" as well as this: stars = sprintf("★ ☆") plot "./mydata" u 1:2 title stars but both of them don't work. Any ideas? 回答1: set term postscript enh color eps set output 'test.eps' set title 'star1:{/ZapfDingbats \110} star2:{/ZapfDingbats \111}' plot sin

问题 Thanks to jaySf I was able to create a pdf file containing beautiful tables with footnotes showing formulas and symbols with R Markdown, Latex, knitr and kableExtra (below his example): --- title: "Untitled" output: pdf_document --- ```{r tab} library(knitr) library(kableExtra) df <- data.frame(v1=rnorm(6), v2=runif(6), v3=rbinom(6, 1, .33), row.names=LETTERS[1:6]) kable(df, "latex", align="c", booktabs=TRUE) %>% footnote(general=c("$a^2+b^2=c^2,$", "$\\\\sigma^2=\\\\frac{1}{n-1}\\\\sum_{i=1}

问题 I've spent several days trying to speed up loading of symbols when debugging crash dumps using WinDbg, and I'm unable to get past a particular problem. The issue is that when symbols for a module in the dump doesn't exist in any accessible symbol store or symbol server location (e.g. it's a third-party modules without available symbols), WinDbg will spend literally hours looking for them. I've set up my symbol path correctly to properly set the search order and the cache directories: .sympath

问题 We have a project for windows store app using WinRT (and XAML, C#). The problem is, that when some exception is thrown and I log the exception using Debug.WriteLine(ex); , there are no line numbers, so I do not know, where actually was the exception thrown. I have of course DEBUG configuration with "full" symbols set in Project Properties > Build > Advanced > Debug Info. At first I thougth that it must be something in our project. HOwever, when I downlaoded some samples from microsoft and put
