问题 I'm following the rastertek tutorial on DirectX while also studying Exception-Safety in Generic Components by David Abrahams (http://www.boost.org/community/exception_safety.html). Why (to the best of anyone's knowledge) is the exception handling set up the way it is in the rastertek tutorial and what level of protection does it offer? For instance: mhresult = D3D11CreateDeviceAndSwapChain(NULL, D3D_DRIVER_TYPE_HARDWARE, NULL, 0, &mfeatureLevel, 1, D3D11_SDK_VERSION, &mswapChainDesc,

问题 I have a library that written mostly in C, Some parts of it should be thread safe and I use global spinlock to protect the critical section of the code. Now my problem is: I should call some callback of the user from inside of a critical section that protected by a spinlock and in case that those callbacks generate an exception, on Windows I have a _ try/ _finally in C to be able to leave the critical section even when an error occurred. Can I accomplish this on UNIX too? 回答1: This is called

问题 I think I have found a nasty bug in PowerShell 4.0 exception handling but I'm new to PowerShell scripting and want to be sure I didn't miss something. I managed to find a code that reproduces the problem: foreach ($id in 1..20) { try { # The objective is to generate basic exceptions and see how they are caught throw "#$id" } # Oddly, if the following block is removed or commented, there is no problem catch [System.ArithmeticException] { Write-Host ("[ArithmeticException] {0}" -f $_.Exception

问题 When my application encounters an exception of type UnauthorizedAccessException during an AJAX request, I want to handle the behaviour myself and return a custom JSON response.

问题 My C# code consumes a COM object. Sometimes that COM object methods will return E_OUTOFMEMORY but it will get translated into System.OutOfMemoryException instead of System.Runtime.InteropServices.COMException with appropriate ErrorCode . This is a problem for me because it complicates my error handling - I'd prefer to have all error indications that arise from COM object methods being thrown as System.Runtime.InteropServices.COMException only. Is it possible to always have System.Runtime
