symbols

问题 I am doing the below. All I get is the basic font, not my custom symbol font. Any ideas? Paint pnt = new Paint(); // SymbolNo is 38. Returns string "&" which is correct in normal font. String symbolText = Character.toString((char)SymbolNo); // Should adopt a symbol font and draw symbol to screen instead. But I just see "&" Typeface tf = Typeface.createFromAsset(m_context.getAssets(), "fonts/myFont.TTF" ); pnt.setTypeface(tf); m_canvas.drawText(symbolText,x, y, pnt); my font is in assets/fonts

问题 I'm running rails3 with rails exception-notifier gem. When an exception occurs, and an email should be sent, I'm getting an exception from the ParameterFilter class. I've found the problem in the rails source, and am not sure the best way to proceed. The problem occurs in ActionDispatch::Http::ParameterFilter. In the compiled_filter method, an error occurs on line 38: key = key.dup when key is a symbol, because symbols are not duplicable. Here is the source: def compiled_filter ... elsif

问题 I am working on a couple of projects (A and B) in a large VS2010 solution (all in C#). There are many cases where methods from project A call through to one or more of the projects in the solution for which I am not responsible, which in turn call through to project B. When stepping through with the debugger from project A, I am forced to step through a host of methods in these other projects, in which I have no interest, before I finally reach the call to project B. Further, when stepping

问题 What could I use in PHP in place of the normal ' and " symbols around something? Example: echo("Hello, World!") 回答1: There are 4 ways to encapsulate strings, single quotes ' , double quotes " , heredoc and nowdoc. Read the full php.net article here. Heredoc A third way to delimit strings is the heredoc syntax: <<<. After this operator, an identifier is provided, then a newline. The string itself follows, and then the same identifier again to close the quotation. http://www.php.net/manual/en

问题 Last week I released the Linux and windows version of an application. And after the release we realized that the symbols were not stripped off, and my manager thinks (and I disagree) that it might allow the user to understand our algorithm. Anyway, now, I will have to clean-up the symbols and re-release the application. My question, What is the best way to strip symbols in Linux? What is the best way to strip symbols in Windows? 回答1: With Visual C++ (and other Microsoft compilers) on Windows,

问题 During a refactor of an iOS project, I ran into this bear of a bug. During the linking phase, I get this message: ld: duplicate symbol _OBJC_IVAR_$_TinCanViewController.currentViewController in /path/to/TinCanViewController-E98A666B7AF2673A.o and /path/to/TinCanViewController-E98A666B7AF2673A.o As far as I can tell, it looks like it claims TinCanViewController-E98A666B7AF2673A.o is declaring the specified symbol twice; both paths are pointing to the exact same .o file. I ran nm on that

问题 This is in DFM.java This part is in the main class Algebra.vect dx = new Algebra.vect(new double[] {2.0,3.0,4.0}); Algebra.matrix eij = new Algebra.matrix(); System.out.println(eij.get(1,1)); dx.set(1,4.0); System.out.println(dx.get(1)); This is in Algebra.java class Algebra { public static class vect { double[] v = new double[3]; public vect() { v[0]=v[1]=v[2]=0; } public vect(double[] v) { this.v=v; } int tamanho() { return v.length; } double get(int i) { return v[i]; } void set(double[] v)

问题 I'm running into a Go behaviour which I don't understand. My idea is to import a plugin which implements an interface that is out of both packages. If a struct is returned it works fine, but to be sure it implements the interface, I want to return an interface which fails. Interface definition: package iface type IPlugin interface{ SayHello(string) SayGoodby(string) WhatsYourName() string } The main program looks like this: package main import ( "plugin" "plugin_test/iface" "errors" "fmt" ) /

问题 I'm calling File.ReadAllText() in a program designed to format some files that I have. Some of these files contain the ® (174) symbol. However, when the text is being read, the returned string contains � (65533) symbols where the ® (174) should be. What would cause this and how can I fix it? 回答1: This is likely due to a mismatch in the Encoding . Use the ReadAllText overload which allows you to specify the proper Encoding to use when reading the file. The default overload will assume UTF-8
