breakpoints

问题 I am using eclipse europa (3.5) on windows vista home premium 64-bit using JDK 1.6.0_18 (32 BIT). Normally, I am able to put breakpoints just fine; However, for a particular class which is NOT part of the project (this class is inside a .JAR file (.JAR file is part of the project) ), although I have attached a source directory to this .JAR file, I am unable to place a breakpoint in this class. If I double-click on the breakpoint pane(left border), I notice that a class breakpoint is placed. I

问题 I have one file, SignInViewController.swift , in my Xcode project that out of nowhere has begun not stopping on breakpoints. I have a breakpoint in viewDidLoad() and a few in viewDidAppear() . I have several print() calls in both functions to make sure they are executing. Breakpoints work fine in other files including AppDelegate.swift . There was a point when I trying to figure out what was wrong where I noticed that while I was building the project an error would appear saying Invalid

问题 If you include a CPP file from another CPP file, XCode refuses to break at any breakpoints in the included CPP file. I'm going to raise a bug with Apple but just wanted to mention it here in case others have come across this and have maybe found ways around it. There are very good reasons that you may want to include CPP files from CPP files which I won't go into here. Suffice to say, I can't simple re-arrange the project to compile the included files directly. Example: A very simple iPhone

问题 This question was migrated from Super User because it can be answered on Stack Overflow. Migrated 10 years ago . I go to Breakpoints panel in XCode, in the 'Breakpoints' I click a breakpoint and click 'Delete', but it does not remove the breakpoint. And I try go to go to 'Project Breakpoints' and find the same breakpoint and click 'Delete'. But it still does not break the breakpoint. 回答1: Drag them out of the bar on the side and they will disappear. You can also press the shortcut ⌘ + \ while

问题 When debugging, changes to breakpoints are only persisted for that debugging session. Once the debugger detaches the breakpoints are restored to their 'pre-debug' state. I can appreciate this is sometimes useful, and understand why it defaults this way. However - does anyone know if there is an option to disable this functionality (in VS2010) such that if I delete/disable/add a breakpoint during debugging the changes will persist the next time I start debugging? 回答1: You can remove the

问题 Been watching a WWDC video today about new features in xCode 4. They have mentioned that it a good idea to use log message actions on breakpoints along with "automatically continue after evaluation actions" enabled to output a variable's value for instance instead of using NSLogs all the time. lets say I have something like that: NSLog(@"URL is : %@", userDocumentsURL); How would I write a log message action to display userDocumentsURL's value? Is it really a good idea to use the above method

问题 When creating a tracepoint in Visual Studio (right-click the breakpoint and choose "When Hit..."), the dialog has this text, emphasis mine: You can include the value of a variable or other expression in the message by placing it in curly braces... What expressions are allowed? 回答1: Microsoft's documentation is rather sparse on the exact details of what is and is not allowed. Most of the below was found by trial and error in the Immediate window. Note that this list is for C++, as that's what

问题 When a breakpoint is hit in Visual Studio, it steals the focus from whatever other application the programmer is viewing/typing into at that moment. This can be very irritating since VS grabs any keyboard input the programmer was typing into the other application at that moment and takes that input as its own. What are the tricks you folks use to prevent this focus steal? (I face this on Visual C++ 2008 and 2010. I am guessing it is a problem for Visual Studio in general and for all recent
