Does anybody know the API, sample code to write msg to the 2000's event log since I am debugging an .EXE invoked from the ASP.

This solution is only available to members.

Create a function to write info to the log:
void CTest1Dlg::LogEvent(const TCHAR* psz, bool bError)
{
const TCHAR* rgsz[] = { psz };
HANDLE hes = RegisterEventSource(0, "My event source");
if(hes)
{
WORD dwEventType = bError ? EVENTLOG_ERROR_TYPE : EVENTLOG_INFORMATION_TYPE;
DWORD dwEventID = bError ? (DWORD)0xE0000001L : (DWORD)0x20000001L;
ReportEvent(hes, dwEventType, 0, dwEventID, 0, 1, 0, rgsz, 0);
DeregisterEventSource(hes)
}
}
and call that function:
LogEvent("test", true);
LogEvent("test", false);

you can download a debugview form www.sysinternals.com, it is a free ware.
then in your program:
TCHAR myBuffer[1024];
..........
_stprintf( myBuffer, _T(" if it is printed, something happened. %u"), uintValue);
::OutputDebugString( myBuffer);
( TRACE macro called this api OutputDebugString too)
then in your release / debug run, you can see the output message in the debugView.
it is a very good tool.
