exception mechanism

[guchangyuan]

i write like this,
try
{
int i = 5;
int j = i / 0;
}
catch (...)
{
qDebug("divided by zero.");
}
use qt in win32, but the catch can't catch the error, direct popup the microsoft's "sorry for inconvenice..." error box.
anyone can teach me a method to solve this.
can qt do it like mfc?

The C++ standard does not guarantee that an exception is thrown on a division by 0. You may need to read up on your compiler's options, maybe it is possible to configure it such that an exception is thrown in that case.
But "usually" your app will just crash.
