I have written a Win32 service in C and am interested in reporting events in the Event Log using the ReportEvent API. This only appends a substring to the main message.
How do I write the MAIN message using C functions

What do you mean by MAIN message ?

ReportEvent(m_hEventSource, wType, 0,dwEventID,NULL, iNumberOfStrings,0,
pArrayOfStrings, NULL)

writes a perfect eventlog entry for me !

Get and unpack the file:
http://www.geocities.com/SiliconValley/1741/miscprog/logging.zip

The "main" messages are defined in directory messages... it is messages.mc se workspace there for example of the compilation MC to BIN :) good luck

or go to http://www.geocities.com/SiliconValley/1741
and download natlib library so You can use nwevlog.h/nwevlog.cpp (TWin32EventLog) to simplify event writing :)

Good Luck
