问题 As i understand it, Java 7's suppressing exceptions feature is an automatic one. In other words, exceptions happening in what used to be a finally block in 6 are automatically suppressed in favor of exception that took place upon resource allocation. So, in this example things may go wrong with a) opening a resource and b) closing a resource or c) possibly both. As i understand it, Java 7 will throw exception that took place upon opening, whom we can ask to give us suppressed exceptions,

问题 This question already has answers here : Globally catch exceptions in a WPF application? (6 answers) Closed 3 years ago . Sometimes, under not reproducible circumstances, my WPF application crashes without any message. The application simply close instantly. Where is the best place to implement the global Try/Catch block. At least I have to implement a messagebox with: "Sorry for the inconvenience ..." 回答1: You can handle the AppDomain.UnhandledException event EDIT: actually, this event is

问题 It seems to me that if you have some C++ code like this: int f() { try { if( do_it() != success ) { throw do_it_failure(); } } catch( const std::exception &e ) { show_error( e.what() ); } } The C++ compiler should be able to optimize the throw and catch into almost a simple goto. However, it seems to me from my experience viewing disassembly and stepping through code that the compilers always jump through the very messy exception handling libraries. Why do they do that? Is there some language

问题 Is there a C# method that returns to the upper-most caller, the Name of MY Method that threw an exception, even if the actual exception was thrown by another (e.g. database driver errors when my method calls it) ? Caller -> MyMethod -> DbDriver(error) I want "MyMethod", not "DbDriver" I'd rather not re-throw exceptions all the way up the chain. My current kludge, is to iterate through the StackTrace frames, and parse out my Method using MethodBase.GetCurrentMethod().DeclaringType . Is there a

问题 I used Hibernate 4.1.2 with Ehcache 2.4.3 (shipped together with hibernate when donwloaded hibernate).

问题 ive checked out some of the other questions and obviously the best solution is to prevent the behavior that causes this issue in the first place, but the problem is very intermittent, and very un-reproduceable. I basically have a main form, with sub forms. The sub forms are shown from menus and/or buttons from the main form like so: private void myToolStripMenuItem_Click(object sender, EventArgs e) { try { xDataForm.Show(); xDataForm.Activate(); } catch (ObjectDisposedException) { MessageBox
