Exception Handling

[Ross]

Hi,

I have a message box that displays the message "Unhandled exception in
Cash32.exe: 0xC000005: access violation".

Is there anyway to write an exception that handles this message. For
example

class microsoft_errors{};

some_function()
{
try{
// some code
if (exception = OxC0000005){
throw microsoft_errors();
else
//Continue as normal;
}
catch(microsoft_errors){
message box ("error found in some_function() in XXX.cpp line X ")
}
}//end function

Thanks
Ross

Please ask in a Microsoft newsgroup: microsoft.public.vc.language.

IIRC, there is a way, but it's not part of C++, it's part of Windows
API or something like that.

You may use catch(...) to catch the rest of the exceptions that you do
not catch with the catch() expressions you already have.
All ISO C++ standard library exceptions are derived from std::exception
defined in <exception>. So for ISO C++ standard library ones you may do:
catch(std::exception &e)
{
// perhaps use e.what().
//
// E.g.
// using namespace System;
//
// MessageBox::Show(__gc new String(e.what()), "Uncaught Exception",
// MessageBoxButtons::OK, MessageBoxIcon::Error);
}
In .NET, all .NET managed exceptions are derived from Exception, you can
use catch(Exception *pe) to catch all .NET managed exceptions.
For example you may do:

catch(System::Exception *pe)
{
using namespace System;

MessageBox::Show(pe->Message, "Uncaught Exception",
MessageBoxButtons::OK, MessageBoxIcon::Error);

Application::Exit();
}
BTW this is off topic in clc++ and you should ask in
microsoft.public.dotnet.languages.vc.
If it doesn't appear in your news server use the public MS news server:

It's OT, but look here.
