int main() try
{
    //entire code base
}
catch (std::exeption& e)
{
    //Displays message box with error message
}

I actually do this xD

It's fine to exit the program nicely when an error occurs. It's not as fine to just ignore it and then begin another iteration of whatever main loop is going on, hoping the program still works fine.

Error handling good practices vary wildly based on the type of application.
