C ++ / CLI：捕获一切（.NET /的Win32 / CRT）异常 [英] C++/CLI: Catching all (.NET/Win32/CRT) exceptions

问题描述

我知道这是令人难以接受的，但我出了选择这里。我正在开发一个C ++ / CLI应用程序，有一个我无法追查错误 - 主要是因为它绕过我目前的崩溃处理程序：

I know this is frowned upon, but I'm out of options here. I'm developing a C++/CLI app that has a bug that I'm unable to track down - mainly because it's bypassing my current crash handler:

AppDomain::CurrentDomain->UnhandledException += gcnew UnhandledExceptionEventHandler(&LogAndExit);
Application::ThreadException += gcnew ThreadExceptionEventHandler(&LogAndExit);
Application::SetUnhandledExceptionMode(UnhandledExceptionMode::CatchException);
try 
{ 
    Application::Run(gcnew frmMain()); 
} 
catch (Exception^ ex) 
{ 
    LogAndExit(ex); 
} 
catch (...) 
{ 
    LogAndExit(); 
}

标准.NET崩溃的处理，我想。 MSDN报道，一些CRT异常将打击在管理堆栈，默默地退出应用程序。

Standard .NET crash handling, I suppose. MSDN reports that some of the CRT exceptions will blow over the managed stack and silently abort the app.

我已经读了_set_invalid_parameter_handler，但即使我得到一个LNK2001错误，现在看来，这不能与/ CLR使用：纯。我说得对，还是我只是PEBKACing起来，缺少一个库文件？

I've been reading up on _set_invalid_parameter_handler, but even though I'm getting a LNK2001 error, it seems it can't be used with /clr:pure. Am I right, or am I just PEBKACing it up and missing a lib file?

推荐答案

你能在运行/ CLR 模式？如果你可以再试试这个：

Can you run in /clr mode? If you can then try this:

#include <exception>

然后：

try
{
    try
    {
        Application::Run(gcnew frmMain()); 
    }
    catch(const exception& ex)
    {
        throw gcnew System::Exception(gcnew System::String(ex.what()));
    }
} 
catch (Exception^ ex) 
{ 
    LogAndExit(ex); 
} 
catch (...) 
{ 
    LogAndExit(); 
}

另外要注意的：：如果您的应用程序是多线程的，那么你就只能望尘莫及从线程中 frmMain（）正在运行。所以，做一个包罗万象的对整个应用程序是不可能在这种情况下！

Another thing to note: if your application is multi-threaded, then you will only catch an exception from the thread in which frmMain() is running. So doing a catch-all on your entire application is impossible in that case!
