C# Signature:

[DllImport("kernel32.dll", SetLastError=true)]
static extern bool SetThreadErrorMode(UInt32 dwNewMode, out UInt32 lpOldMode);

Use the same flags as for SetErrorMode (minus SEM_NOALIGNMENTFAULTEXCEPT = 0x0004):

        [Flags]

Flags

        public enum ErrorModes : uint
        {
            SYSTEM_DEFAULT = 0x0,
            SEM_FAILCRITICALERRORS = 0x0001,
            SEM_NOGPFAULTERRORBOX = 0x0002,
            SEM_NOOPENFILEERRORBOX = 0x8000
        }

VB Signature:

    Public Enum ErrorModes As UInteger
        SYSTEM_DEFAULT = &H0
        SEM_FAILCRITICALERRORS = &H1
        SEM_NOGPFAULTERRORBOX = &H2
        SEM_NOOPENFILEERRORBOX = &H8000
    End Enum

Notes:

From the Microsoft documentation for SetErrorMode, for systems running Windows 7 and later, "Callers should favor SetThreadErrorMode over SetErrorMode since it is less disruptive to the normal behavior of the system." This API is not supported on systems running versions of Windows that are older than 7.
