- Cache localized hard error message components: the status severity,
the system process name and the unhandled exception debug strings.
- Try not to fail too much. In particular, don't fail if a string could
not be correctly captured in UserpCaptureStringParameters() (we then
use a default empty string). The next aim is to make UserpFormatMessages()
not failing at all.
- Use RtlStringCbPrintf(Ex)W where possible so that one can use counted
(and not NULL-terminated) UNICODE_STRINGs where possible. This allows
using counted resource strings without having to allocate memory.
- If available, prepend the window title of the application that
triggered the hard error to the hard error message box caption.
In particular do not always fail as soon as there is an error, because they may be the sign of an OS problem and this is precisely in this case that we want to display a hard-error.
- Use hard-error captions depending on the status code severity.
- Improve handling of the STATUS_UNHANDLED_EXCEPTION error. Start
implementing the display of the dialog button descriptions ("OK" to
terminate the application; "Cancel" to debug the application).
- Add support for the "ErrorMode" and "ShellErrorMode" registry values
under HKLM\System\CurrentControlSet\Control\Windows.
- Use MessageBoxTimeoutW() in UserpMessageBox() to support different
message box timeouts.
- Log hard errors into the System event log.
