callstack

问题 When an error occurs in a function, I'd like to know the sequence of events that lead up to it, especially when that function is called from a dozen different places. Is there any way to retrieve the call stack in VB6, or do I have to do it the hard way (e.g., log entries in every function and error handler, etc.)? 回答1: I'm pretty sure you have to do it the hard way. At a previous job of mine, we had a very elegant error handling process for VB6 with DCOM components. However, it was a lot

问题 In a previous question (Get object call hierarchy), I got this interesting answer: The call stack is not there to tell you where you came from. It is to tell you where you are going next. As far as I know, when arriving at a function call, a program generally does the following: In calling code: store return address (on the call stack) save registers' states (on the call stack) write parameters that will be passed to function (on the call stack or in registers) jump to target function In

问题 Today I was debugging my android app and it crashes. Here is the call stack: android.content.res.Resources$NotFoundException: String resource ID #0x8822 at android.content.res.Resources.getText(Resources.java:246) at android.widget.TextView.setText(TextView.java:3860) at com.whackanandroid.GameActivity.gameOver(GameActivity.java:68) at com.whackanandroid.Game$1.onCountDownFinished(Game.java:79) at com.whackanandroid.CountDown$1.run(CountDown.java:23) at android.os.Handler.handleCallback

问题 I've implemented a working multithreaded merge sort in C++, but I've hit a wall. In my implementation, I recursively split an input vector into two parts, and then thread these two parts: void MergeSort(vector<int> *in) { if(in->size() < 2) return; vector<int>::iterator ite = in->begin(); vector<int> left = vector<int> (ite, ite + in->size()/2); vector<int> right = vector<int> (ite + in->size()/2, in->end() ); //current thread spawns 2 threads HERE thread t1 = thread(MergeSort, &left); thread

问题 I seem to be having an issue using the call stack viewing functionality of Microsoft Visual Studio 2010 Professional. During debugging, my application crashed, so I inspected it with the call stack view. The offending line was contained within called showInDGV(...) nothing exciting, just trying to read an uninitialized variable or something... All well and good, so next thing I did was check to see where the call to showInDGV() was coming from, because it is called from multiple places. When

问题 I have a .NET application with a button. When I click the button I want the application to print thread stack of all threads to debug console. Is it possible to do it? Datte. 回答1: You can use the StackTrace class ( System.Diagnostics ) to get a stack trace of a Thread . You'd need to enumerate the threads, and (unfortunately) suspend them first, though. Here's the constructor of interest: http://msdn.microsoft.com/en-us/library/t2k35tat.aspx You may well need to create your own ThreadPool

问题 is there some approach to make singleton class initialize on programs stack (hence members variables also)? I have tried following, both were failed: 1) class CStack{ public: void* getAlloc(long); static CStack& Instance(){ static CStack theStack; return theStack; } private: bool _data[100]; CStack(){}; CStack(const CStack&); CStack& operator=(const CStack&); }; 2) class CStack{ public: void* getAlloc(long); static CStack* Instance(); private: CStack(){}; CStack(CStack const&){}; CStack&

问题 I have a couple of colleagues looking at some bad code in Excel VBA, wondering is there a limit to the number of levels in a call stack 回答1: Unless the function is tail-recursive and VBA can handle that (which it can't), you'll run into a stack overflow. As a simple test I hacked together the following snippet: Dim count As Integer Sub Rec() count = count + 1 Cells(1, 1) = count Call Rec End Sub which tells us that the limit for this is 4007 iterations, at least in my version of Excel 2007

问题 After being introduced to the call stack window by this ASP.NET MVC video I've attempted to understand how it works. My understanding was that it shows all of the method calls - in the order they were called. However its always blank whilst I'm debugging - am I doing something wrong? 回答1: Ahh - As is usually the case once I've asked a question I work it out! Its turns out it is only shown when a breakpoint has been hit 来源： https://stackoverflow.com/questions/4690332/call-stack-window-always
