问题 This question already has answers here : WPF global exception handler [duplicate] (9 answers) Closed 7 years ago . I'm working on a project that is implemented using plain threads . Most of the expected exceptions in the application are handled, however, there are cases where one of the threads throws an unexpected exception and the application just crashes (the application is both I/O and Client-Server based so it's practically impossible to handle all the exceptions). To fix this, I'm

问题 I wanted to use a crash reporter in my own Revit addin but AppDomain.CurrentDomain.UnhandledException is never called. It seems Revit itself manages the unhandled expections and shows its own crash dialog. What should I do to catch all unhandled exceptions in revit addin before Revit cathes them? I already tried the following lines of code but it does not work: it never enters the handler method: public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements) {

问题 I created Windows Form Application from Blank Project Template. It seems like the .Net Unhandled Exception not enabled by default.

问题 I have the following code. And it works as expected without throwing a unhandled rejection error. p = new Promise (fulfill, reject) -> reject new Error 'some error' p.catch (error) -> console.log error Now, the second code example does throw an unhandled rejection error.

I'm

问题 I try to get rid of some of the boost dependencies in my code and instead use the new C++11 features (Visual Studio 2013). In one of my components I used boost::mutex together with boost::lock_guard<boost::mutex> and everything worked fine. When I use std::mutex together with std::lock_guard<std::mutex> instead, I get the following error when returning from main() . Unhandled exception at 0x7721E3BE (ntdll.dll) in GrabberTester.exe: 0xC0000005: Access violation reading location 0xA6A6B491.

问题 I have a Windows Mobile program that accesses an attached device through a third-party DLL. Each call to the device can take an unknown length of time, so each call includes a timeout property. If the call takes longer than the specified timeout to return, the DLL instead throws an exception which my app catches with no problem. The problem that I have is with closing the application. If my application has made a call to the DLL and is waiting for the timeout to occur, and I then close the
