debugging

问题 I already know how to pass parameters in GDB mode by running: "run parameters". However, when continuing to debug by using n or s to go, I would like to pass data to my program, let say a text/string. For example, I want to send a string as "Testing" to my program because my program always waits to receive command from console. If I type "Testing" it will say "undefined command: "Testing". Try help". (gdb) b 100 (gdb) run "pass parameters to program here" (gdb) n (gdb) Now I want to send a

问题 I have the Disassembly tab open in Visual Studio. (There is no source code available.) I can't figure this out: How do I put a breakpoint at the beginning of the exported function Foo in the DLL Bar.dll ? 来源： https://stackoverflow.com/questions/7737798/go-to-symbol-in-visual-studio-disassembly

问题 I have done it like this but it always give the error: error: use of undeclared identifier 'self' error: 1 errors parsing expression 回答1: I don't believe that you can access any symbolic information from a breakpoint inside the UIKit framework, because there is no debugging information available. If you set a breakpoint and allow the debugger to open you will see you are just presented with some assembler code and a set of registers. You can set a breakpoint for a specific UIViewController

问题 I have built a UWP app, and a WPF app within the same solution. I am using the Full​Trust​Process​Launcher class to launch the WPF app from the UWP app. I am also using the App​Service​Connection class to allow the two apps to communicate with each other. This all works fine in a basic scenario. But once I start really developing my WPF app beyond the samples I can find I will need to start debugging in visual studio. I've tried the following: Set breakpoints within the WPF code. Result : I

问题 Is there any tool (preferably extension/add-on to any browser) that allows you to see all the value changes of the desired JS variable in real time? Previously I did something like this (in pure JS): var someVariable; var previousValueOfSomeVariable; var f = function() { if (previousValueOfSomeVariable != someVariable) { console.log(Date.now(), someVariable); previousValueOfSomeVariable = someVariable; } } var TO = setInterval(f, 100); It did the trick, but was, of course, inefficient (in

问题 I am using Redux with Flutter for state management. Whenever I dispatch an action, I want to know which widgets were re-rendered. Is there any way of doing it? 回答1: In flutter, whenever one widget update ; the whole widget tree repaint. So... no. But you can also introduce "repaint boundaries" manually by inserting in your tree a RepaintBoundary widget. This explicitly tells flutter to create a new painting layer for it's child (which implies memory cache). So that whenever that child updates

问题 I'm using the pyscss compiler in the python webassets library with webassets debug configs all set to true. But when I make changes to an scss file and reload the page that includes the generated css file, I see that the css file has not be regenerated and does not include my changes. Why is this happening? 回答1: Use depends='*.scss' as noted in this issue on GitHub. 回答2: Figured it out. Webassets does not pick up on changes to scss files that are included in other scss files using @import .

问题 I have an Access application that use the classical front-end/back-end approach. Yesterday, the backend got corrupted for a reason I don't know. So I opened the backend with Access 2003 and access asked me if I wanted to repair the file, I said yes and it seemed to work. I can open the database see the tables contents and run most of the queries. However there is an access query that doesn't work with a specific where clause. Example : // This works in the original DB, but not in the
