Redirect the CRT assertions to a text file

I am writing a C program that uses a file to capture the Microsoft CRT
assertions. The related code is like below:

=====================================================
invalid_parameter_handler oldHandler, newHandler;
#if defined(DEBUG)
HANDLE hLogFile;

hLogFile = CreateFile(L"c:\\assertlog.txt", GENERIC_WRITE,
FILE_SHARE_WRITE|FILE_SHARE_READ, NULL, OPEN_ALWAYS,
FILE_ATTRIBUTE_NORMAL, NULL);
newHandler = invalidParamHandler;
oldHandler = _set_invalid_parameter_handler(newHandler);

_CrtSetReportMode(_CRT_ASSERT, _CRTDBG_MODE_FILE);
_CrtSetReportFile(_CRT_ASSERT, hLogFile);
#endif
=====================================================

The above code works when I run my program as a console application. However
when I run my program as a Windows service then nothing is captured in the
c:\assertlog.txt even when an assertion should happen.

Does anyone know what changes should be made for a Windows service to
redirect the CRT assertions to a text file?

Your response will be very appreciated!
