  Re: Problem in writing Event log from ISAPI Filter Reply Contact thanks Ganesh I resolved my problem using following. Following code write the logs sucessfully in Event log Viewer.  int grades [] =  {   EVENTLOG_SUCCESS,    EVENTLOG_INFORMATION_TYPE,    EVENTLOG_WARNING_TYPE,    EVENTLOG_ERROR_TYPE,  };    // Use event logging to log the error.  //  static HANDLE  hEventSource = NULL;  if ( hEventSource == NULL ) hEventSource = RegisterEventSource(NULL, TEXT("Agrando_ISAPI"));  LPTSTR  lpszStrings[1];  lpszStrings[0] = "My test Message to check in  Event Viewer";    if (hEventSource != NULL) {   bool a = ReportEvent(hEventSource, // handle of event source    grades[0],  // event type    0,                    // event category    1,                    // event ID    NULL,                 // current user's SID    1,                    // strings in lpszStrings    0,                    // no bytes of raw data    (const char**)lpszStrings,          // array of error strings    NULL);                // no raw data      //(VOID) DeregisterEventSource(hEventSource);  }
