The error mode indicates to the system how the application is going to respond to serious errors. Serious errors include disk failure, drive-not-ready errors, data misalignment, and unhandled exceptions. This error mode can be managed by either a per-thread or per-process basis. An application can let the system display a message box informing the user that an error has occurred, or it can handle the errors.
To handle these errors without user intervention, use SetErrorMode or the thread-specific SetThreadErrorMode. After calling one of these functions and specifying appropriate flags, the system will not display the corresponding error message boxes.
A process can retrieve its error mode using GetErrorMode or GetThreadErrorMode.
Best practice is that all applications call the process-wide SetErrorMode function with a parameter of SEM_FAILCRITICALERRORS at startup. This is to prevent error mode dialogs from hanging the application.
Other than that, callers should favor the thread-specific versions of these functions since they are less disruptive to the normal behavior of the system.
