I wrote the following code to browse websites:

CInternetSession session;
    CStdioFile * pFile1 = NULL;
    URLadr ="http://abo.spiegel.de//60quiz"; //e.g. empty or non existing
website

    try
        {
            pFile1 = session.OpenURL(
                                URLadr,
                                0,
                                INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_KEEP_CONNECTION,
                                NULL,
                                0
                                );// >>C R A S H
        }
    catch(CInternetException e)
        {
            //.....exeption handling
        }
It works mostly fine but chrashes if an empty or non existing URL is
given.

There is no such thing as a crash. There is an access violation, a stack
poverflow, a C++ exception, an assertatin failure ...
I've tried the code, and there was no crash, it was just a C++ exception thrown.

What exactly happens when you run that code?

Try - catch does not work here - it crashes when session.OpenURL(...)
is invoked.

OpenUrl throws a CInternetException* exception, not a CInternetException.
