C# Signature:

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

Use the same flags as for SetErrorMode:

Flags

        public enum ErrorModes : uint
        {
            SYSTEM_DEFAULT = 0x0,
            SEM_FAILCRITICALERRORS = 0x0001,
            SEM_NOALIGNMENTFAULTEXCEPT = 0x0004,
            SEM_NOGPFAULTERRORBOX = 0x0002,
            SEM_NOOPENFILEERRORBOX = 0x8000
        }

VB Signature:

Declare Function SetThreadErrorMode Lib "kernel32.dll" (ByVal dwNewMode as System.UInt32, ByRef lpOldMode as System.UInt32) As System.Boolean

Declare Function SetThreadErrorMode Lib "kernel32.dll" (TODO) As TODO

User-Defined Types:

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.
