There is a fn called SetErrorMode. Prototype is as follows :
SetErrorMode(UINT uMode) // set of bit flags that specify
The bitflags you're looking for are SEM_NOOPENFILEERRORBOX, which has a
value of 0x8000, and SEM_NOGPFAULTERRORBOX (0x0002). There are other
possible values, which can be determined by consulting any
reasonbly-complete API reference.
If you have the SEM_NOOPENFILEERRORBOX flag set when you call
SetErrorMode, you're telling the OS to return an error to you, and you
(i.e. your application) will handle it. Note that the documentation I
consulted (msvc 4.x), stated that with SEM_NOGPFAULTERRORBOX, the
application needed to be a debugger that is coded to handle such
exceptions via an exception-handling mechanism.
I hope you find this useful!
