breakpoints

问题 I have a program that acts as a debugger. I set a hw bp for a thread setting dr0 to the address I want to bp to be in and dr7 as 1 because I want the bp to generate an event each time that address is executed. It works but the problem now is that I don't stop receiving the EXCEPTION_SINGLE_STEP all the time. I created a loop with WaitForDebugEvent as normal: DebugActiveProcess(pid); while (flag == 0) { WaitForDebugEvent(&DBEvent, INFINITE); if (first_time){ setHWBPInCurrentThreads(pid,

问题 I need to keep building my project until the debugger actually works by stopping on breakpoints. It's really annoying. Some builds stop on breakpoints, some don't. This answer no longer seems to be relevant to my particular issue. 来源： https://stackoverflow.com/questions/57117144/breakpoints-only-sometimes-work-in-xcode-10

问题 There are some breakpoints in my project that for some reason can not be turned off or deleted. How can I delete these? I heard that they can be deleted by deleting a file with the extension .dsk, but I can't find that file. Where is it? 回答1: There are 4 solutions i have provided which you can try. Sometimes all you need to do is click and drag the breakpoint one by one in your project and drag it off the screen. If that doesn't work try these options. At least one will definitely work.

问题 Suppose I have the following python code: import dummy def run(): print('Running calc() function') y = dummy.perform_very_long_calculation() out = calc(y) #BP1 is here print(out) def calc(x): print('Calculating ...') return x+2 #BP2 is here run() The goal is to have this flow: Put a debug break-point ("BP1") on "out = calc(y)" line. Put a debug break-point ("BP2") on "return x+2" line. Run the module and stop on this "BP1". Call calc(y) from the interactive debug console. Stop on "BP2". debug

问题 I have been using Visual Studio 2005 and 2008 and i have noticed that sometimes when i place break point in my code that it does not want to go to the break point. So i restart my PC and then it works again. Its like something get's stuck? Does this only happen to me??? How can i prevent this! It is driving me nuts!! Thanks in advance!! 回答1: Often this is because the code you are looking hasn't been compiled since you placed the breakpoint, so you test code / unit test, is running against an

问题 I set a function ( All Exceptions ) in Xcode , I have not set any breakpoint , but when start my App that the Xcode automatic to execute breakpoint for the main function . I cannot understand it and i cannot solve it . please help me to answer the question . thanks very much . it's the image , thanks to read : 回答1: If you set All Exceptions breakpoint, the app breaks not only on severe errors, but on possible errors as well. If you want to debug in a particular place, then enable the

问题 Could anyone tell me how to set memory breakpoint in Eclipse (C++)? for example: int a = 0; for(int i = 0; i < 100; i++) { if(i == 50) a = 50; } I want to detect the action when a is assigned to a new value. I know in Visual Studio we should set memory break point by getting the address of a (i.e. &a ). Is there an equivalent way in Eclipse? Your help would be highly appreciated. Thanks. 回答1: maybe this helps: http://www.linuxtopia.org/online_books/eclipse_documentation/eclipse_c_c++_guide

问题 Sometimes there are pieces of code where exceptions occur that you don't want to stop execution in the IDE (e.g. OLE exceptions when setting up a connection). The trick is to place 2 breakpoints around this, with the 1st set to "Ignore subsequent exceptions" and the 2nd to "Handle subsequent exceptions". This works fine when you are the only one working on the code, the breakpoint moves with the code. However, when several developers update the same file and you import/export from/to version

问题 I would like to set breakpoints only at some kind of wrong behaviour hints (e.g. ERROR-trace macros, etc.) for being able to find possible errors early during development. So, I wonder if it is possible to set BPs at places in code found by regex? May-be using some scripting or automation features of VS. Thank you for any hint! 回答1: You can place a breakpoint on all overloaded versions of a method in Visual Studio using this trick : write the name of the method in the search box (main toolbar

问题 I'd like to inspect some global variables before a crash happens. The issue only reproduces on a certain stack trace and setting a breakpoint on the innermost function (or any other from the stack) will not get me close enough. Can I achieve the result of breaking only when the top of the stack contains something like this ? #0 __GI_connect #1 curl_connect #2 get_file #3 init_assets Just doing b init_assets c b get_file c ... doesn't work since init_assets is called multiple times and it
