stack-trace

问题 I'm getting a NullPointerException in a Nokia S40. I want to know what is causing this exception. The device shows: NullPointerException java/lang/NullPointerException This error only occurs in the device, running in the emulator the application works fine. I use microlog to debug my application. But the application works fine if the log is enabled. Is there a way to get the stack trace when I get this NullPointerException? I don't need all details like the line number just which method cause

问题 I have two examples. In the first case, debugger catches the unhandled exception: static void Main(string[] args) { Exec(); } static void Exec() { throw new Exception(); } And the exception has full stacktrace: at ConsoleApplication28.Program.Exec() at ConsoleApplication28.Program.Main(String[] args) at System.AppDomain._nExecuteAssembly(RuntimeAssembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft

问题 I'm working on a hands-off log mechanism for my c# application. Here's what I'd like it to look like: function a(arg1, arg2, arg 3.....) calls function b(arg4,arg5,arg6....) , which in turn calls log() which is than able to detect the stacktrace (this can be done via Environment.StackTrace ) and the values with which each function (e.g. a and b ) in the stacktrace is called. I want it to work in debug and release mode (or, at least, in debug mode). Is this possible to do in .net? 回答1:

问题 I am using the NLog logging framework and am trying to get exception and stacktrace information showing up in any UDP logger appliaction, such as Sentinel and Log2Console, but can only get the log message part displayed. Outputting to a file works well as most examples do just that, so the problem revolves around using network targets with NLog. Bonus if a custom format can be applied on inner exceptions and stacktrace, but this is not required. Exception.ToString() would go a long way. Note

问题 I am rather new to nodejs so I will explain in a bit more detail what I am trying to do. I have a webserver. If a request fails I want to log the stack trace of that exception, but deliver a error page and not crash the server. As an example, the function handling the requests: var Q = require('q'); var requestHandler = function () { // Here I get the data etc. that was requested. As this is not important, just a dummy here Q.resolve() // Now I answer the request .then(function (data) { //

问题 I am working on a class which I would like to use to log the current Call Stack on computers with Windows Vista/7. (Very similar to “Walking the callstack” http://www.codeproject.com/Articles/11132/Walking-the-callstack). First I used RtlCaptureContext to get the current context record then I used StackWalk64 to get the individual stack frames. Now, I realized that the Program counter in STACKFRAME64.AddrPC actually changes for a specific code line whenever I close my program and start it

问题 After being able to determine call stack successfully (in my previous questions) - I was bit puzzled with opengl drivers.

问题 I am looking for a simple way to pull the stack trace out of a Linux core dump file programmatically, without having to invoke gdb. Anybody has an idea? To avoid confusion: I am not looking for a way to get my own back trace from inside a process. I am looking for a way to get a backtrace out of a completely independent core dump file I have. 回答1: If you really can't invoke gdb, but want a backtrace like the ones it provides, you could just copy the bits of gdb's source that are needed for
