Hi all, I fail to catch run-time check errors in my code in the right place. I always end up in my catch(...) function. Instead, I need to be able to identify what exception type that occured. (I do not use any own throw commands.) Please help! my code (simplified): catch ( CException & e) { //MFC base top class(?) logger("CException handler"); } catch( exception ) { // standard c++ top class(?) logger("Exception handler"); } catch (...){ logger("-default exception handler"); } Erik [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Quote: I always end up in my catch(...) function. Instead, I need to be able to identify what exception type that occured. (I do not use any own throw commands.) My guess is, that some function you use throws an exception that's not derrived from CException or exception. I would suggest that you check out the function-documentation if there are any hints about the exceptions used. If not, I can't think of any possibility to get info about the exception. regards, sev [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Please help! my code (simplified): catch ( CException & e) { //MFC base top class(?) logger("CException handler"); } The above is Microsoft MFC specific, you need to ask about it form Microsoft Quote: catch( exception ) { // standard c++ top class(?) Nope. It is std::exception. If you happen to have something called exception (a visible name, other than the std::exception) you will not catch standard exceptions. How did you test that you are not catching the exceptions? I mean did you run under the debugger and it told you there was standard/MFC exception thrown? -- WW aka Attila [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

I always end up in my catch(...) function. Instead, I need to be able to identify what exception type that occured. (I do not use any own throw commands.) I suspect you might have encountered Microsoft's Structured Exception Handling. This throws on null pointer use (MS->Access Violations) and lots of other undefined behavior. It is a conforming extension in that regards. IIRC, Run-time check errors are similar implementations of behavior that the standard left to the compiler vendors. Therefore you must check your compiler documentation. Assuming MSVC again, that would be the MSDN collection.
