breakpoints

问题 I am debugging a Java program in Eclipse. I would like to watch a specific variable. However, since my program uses a GUI, creating a breakpoint causes the window to freeze. This is particularly annoying when e.g. trying to right click on an item and navigate a context menu. I don't actually want to stop the program, I just want to watch a specific variable and log its value every time a certain line is reached. At the moment, I am doing that with print statements, but I was wondering whether

问题 I recently installed the Update 2. So now when I put a breakpoint it just puts a red dot on the left side of the file, but it doesn't highlight the entire line. I am not sure if Update 2 changed the settings, but I thought so. I tried this: in Tools>Options>Debugger>General>Highlight entire source line for breakpoints and current statement (C++ only) . So it tells that this doesn't work for C#. What should I do to highlight the entire line? UPDATE: 回答1: I had the same problem and it went away

问题 In my project that based on asyncio and asyncio tcp connections that debugs with PyCharm debugger I got very and very very absurd errors. If I put breakpoint on code after running, the breakpoint never fires. But breakpoints fires if breakpoint has been put before starting program. But in some cases the firing on breakpoints causes strange errors (if paused on breakpoint and resumed). The next exceptions I remarked: TypeError: 'coroutine' object not callable SystemError: unknown opcode First

问题 This is a question towards programmers who have experience with using Visual Studio 2010 for debugging external applications. Currently, I'm developping an add-on for a program made by people I work for. In order to make this add-on work with the external program, I have to place the .dll file in a certain folder, specified by the external program. I have my build settings configurated so the .dll file is copied automatically. I also copy the .pdb file to enable debugging options. Since this

问题 I have a bool variable which should be true, but is sometimes set to false. I have set a memory breakpoint to see what is changing that. To my surprise, the breakpoint did not hit, but the variable went to false again. What could change the memory without memory breakpoint catching it? 回答1: A few thoughts. If you pass the bool value into a kernel function and THAT is changing it (or perhaps a kernel function call is overwriting memory because it is called incorrectly) then that won't fire a

问题 I'm trying to debug my service but I'm unable to since breakpoints do not work. Yes, I have used android.os.Debug.waitForDebugger(), doesn't matter where I use it (before the line, in the onstartcommand, in the method) it doesn't work. I have my breakpoints set, the service does not stop at them. I have tried them on a normal activity, they work fine there. 回答1: In AndroidManifest.xml add the property android:process=":sync" to the service entry: <service android:name=".SyncService" android

问题 When I'm debugging and the app hits an breakpoint, I can debug normally for a while. Some time later, Android displays the ANR Dialog, but I still can debug normally. If I don't click on the Phone's screen, it ends the debug, so I need to keep my eye on the screen when debugging and that's annoying and really wastes my time, because sometimes the dialog keeps popping every 10 seconds. I don't know what is causing this. I tried restarting the Machine, Phone, ADB and already tried using

问题 I'm trying to analyze and reverse a Objective-C program I have. I made few modifications to the executable by changing some opcodes by hand. When I test the modified software, however, I get Killed: 9 That's fine, I think I touched something I should not. I launched then gdb myprogram in order to analyze the error. Here something (strange to me) happened: if I do not put any breakpoint the program receives SIGKILL, while if I try to put a breakpoint few lines before the one in which I receive

问题 I'm trying to add a breakpoint to the selected .m file in my current XCode project using AppleScript. Right now I'm stuck since AppleScript keeps returning 'missing value' when trying to add a file breakpoint. My current AppleScript looks like this (where PROJECTNAME obviously is the name of my current project) : tell application "Xcode" -- Get the name of the selected document set selectedFile to text document 1 whose name ends with (word -1 of (get name of window 1)) set nameOfSelectedFile

问题 Xcode:Run>Show>Breakpoints I've added the obligatory [NSExceptionRaise] and objc_exception_throw yet when I close the Breakpoints window and then return Xcode adds a third breakpoint: -[NSExceptionRaise] . Does this mean [NSExceptionRaise] is wrong and I should delete it? Or are they both helpful? If so in what way are they functionally different? 回答1: The correct breakpoint is: -[NSException raise] You're instructing the debugger to break on the -raise method of the NSException class. "
