Exception Nr. " << e << endl; } return 0; } Structured Exception Handling When a SEH exception occurs, you typically see a window of Dr. See Project Properties -> C/C++ -> Code Generation -> Modify the Enable C++ Exceptions to "Yes With SEH Exceptions". If you've removed every catch(...) from your program, and given its propensity to catch untranslated SEs, this really should be SOP in general, and you still don't get a dialog box is there some way for me to determine whether pObject was deallocated? this contact form

Exception Handling Model You can set an exception handling model for your Visual C++ compiler with /EHs (or EHsc) to specify synchronous exception handling model, or /EHa to specify asynchronous exception Personally I think that is an absolute gift to the developer community. Watson's window still appears instead of the CrashRpt window. To avoid the side effects with /EHa, we can write code as following in VC 2005 with /EHs: void appGo() { try { // application run…. } catch(…) { } }

__try __except

I'm not sure whether this causes a fetch or a write error. Look up the phrase "first chance exception" in the MSDN and you'll see that these are rarely interesting. Are these documented somewhere?

You should probably google for all reasons catch(...) is evil and make sure you really want to do this. note that in a large organization, there are good and bad programmers. __try __except If you plan to use CRT as a static link library (which is not recommended) and want to use some exception handling functionality, you have to build the functionality as a Yes With Seh Exceptions The following compiler switch (/EHa) should be what you need to make it work: http://msdn2.microsoft.com/en-us/library/1deeycx5.aspx   Thursday, September 21, 2006 8:28 PM Reply | Quote Moderator All replies 3 Sign in

Roger 2 July 2009 at 10:17 am This is one of the most informative articles I have seen on Exception Handling. http://jscience.net/access-violation/access-violation-msado15-dll.html In general, when a computer program program causes (say) a memory access violation, the program could either: continue in a consistent state; crash immediately; or continue in an inconsistent state, possibly Then an exception is raised and caught by an exception handler.

This function works for all threads of the caller process. Recovering from EIP jump voilation is never possible unless you are dodgy and keep assembly level instruction pointers. A handler function (optionally) retrieves exception information and invokes crash minidump generation code, then it terminates process with TerminateProcess() function call. http://jscience.net/access-violation/dll-access-violation.html Things like access violations or division by zero errors are more like "machine" exceptions, rather than language-level things that you can catch.

Handleprocesscorruptedstateexceptionsattribute However, it is obviously useful to catch these types of exceptions in the normal try { } catch (exception ex) { } way for error reporting and more a graceful exit You can verify it quite easily - after the library has been loaded call ::set_terminate() and provide your own function and check if it is being called prior to your program

Maybe I misunderstand this.

This raises an operating system exception, NOT a C++ one. Each new thread needs to install its own // terminate function. What you need to do is to set you own undhandled exception handler. Exception_execute_handler I once wrote a UI for a backend graphics library that needed some debugging.

Several project modules may share a single CRT DLL. This reduces to minimum the overall size of the linked CRT code. callback functions. How can I slow down rsync?
