VS set debugging exception trigger how to do, many novices are not very clear about this, in order to help you solve this problem, the following small series will explain in detail for everyone, there are people who need this can learn, I hope you can gain something.

description

By default, VS2005 and VS2010 do not have exception triggers set to start debugging. You can select exception under menu debugging, and then check all abnormal interrupt cases:

C++ Exceptions

Common Language Runtime Exceptions

...

role

Accurately locate existing problems in the program, rather than crash and exit directly

note

The debugging exception information set by the user is saved in the.suo(Solution User Operation) file. If this file is not uploaded to the svn server, the debugging exception option must be reset when others download the code. If no user modifications are made, the default may not generate a.suo file, which also saves the user's layout settings

Effects in actual application scenarios

1）

In the module to achieve dynamic loading of the project inside, can call exceptions, accurately locate the exception error situation, usually null pointer

2）

When handling 0xfeefeefee pointer errors, you can accurately locate the wrong code.

3）

char szTestString[3600*1058*3] = {0};

In fact, the default stack only has 2M space. The above code exceeds the stack range and causes the program to crash. After opening the exception setting, a prompt appears: 0xC0000FD: Stack overflow

4)Run-Time Check Failure #2 - Stack around the variable 'szError' was corrupted

_TCHAR szError[32] = { 0 };

wsprintf(szError, _T("avcodec_send_packet:%d\n"), nRet);

OutputDebugString(szError);

Cause: If nRet is a very large integer, it will cause the array to go out of bounds, causing the program to crash.

impact

Symptom: When using the VS2005 c++ debugger, the file cannot be opened using the file dialog box. As long as the open file dialog box is executed, the most likely exception at 0x7703c54f is reported: 0x00006BA: RPC server unavailable error.

solution

Because debugging needs to check all exceptions in the debugging menu, remove the check marks, and the problem is solved.
