debugging

问题 In my project which is a hybrid project (in previous it was a web forms project that then we modified to use mvc pattern). Now I want that in debug mode, I want to change something in my cs file, and then I want the changed code to run. I've tried enabling and disabling tools -> options -> debug -> edit and continue checkbox part. When it is enabled I can't change code in my project while debugging. When it is disabled I can change code but it does not affect on running part. for example. int

问题 I need to debug an HTML app on ipad. I used to be able to connect ipad by USB cable to my mac and it would show in the "Develop" menu in Safari. I have two ipads now - one with iOS 6 and another with iOS 7. The iOS 6 one is showing correctly and I can access the web inspector from my mac. iOS 7 ipad is not showing in the "Develop" menu. I have the latest version of iOS installed (version 7.1) and the latest version of Safari (7.0.2) on Maverick. Any suggestions are welcome. 回答1: Enable web

问题 I would like to write a function that accesses the file and line number of the location in which it gets called. It would look like this: fn main() { prints_calling_location(); // would print `called from line: 2` prints_calling_location(); // would print `called from line: 3` } fn prints_calling_location() { let caller_line_number = /* ??? */; println!("called from line: {}", caller_line_number); } 回答1: RFC 2091: Implicit caller location adds the track_caller feature which enables a function

问题 I have my (native C++) DLL project and a corresponding test EXE project based on Google Test. While debugging my DLL via this EXE I have exceptions automatically handled by Google Test. So if my DLL throws an unhandled exception during debug, I expect to see error message from Visual Studio with debug session paused after the code caused exception. Instead, I have breakpoint triggered in gtest.cc. And if I disable --gtest_break_on_failure flag I will receive no breaks at all. I found no such

问题 I have below code which uses static objects of BasicDataSource, Sql Connection, Statement and ResultSet. The code below is working fine, but i just want to know about the safety of using these kinds of coding practices. or how can i optimize the below code so that it can become more stable and can reliable. public class Testing { static BasicDataSource bds = DBConnection.getInstance().getBds(); static Connection con = null; static PreparedStatement stmt = null; static ResultSet rs = null;

问题 I am trying to debug a HLSL shader in VS2012 using NSight, but it can't start. When I click on "Start Graphics Debugging", it seems like it starts the app for a moment, and then closes it (output windows from NSight shows several "shader loaded"/"shader unloaded" lines). Windows Event log doesn't show anything (except "NVIDIA Network Service" failing to start, but if I understood well, this is something related to updates). On the other hand, if I start GPU Perfomannce analysis, then it runs
