QuestionProgramming the Windows Vista Event Log Pin
Shashi.Shinde31-Aug-08 23:15

Hello,



This is with reference to an article at http://www.developer.com/net/cplus/article.php/3624581 about Programming the Windows Vista Event Log.



We build and run the application as per information found in this article. And getting the Operational and Debug events.

Thats great.

Now, we have made some changes and getting some wrong output.

I request you to have quick look on the following stuff and let us know where we are wrong.



We have made some changes in the code as follows –

The manifest.h file contains –

#pragma once

EXTERN_C __declspec(selectany) const GUID MYCOMPANY_HPFS_PUBLISHER = {0x9cde86c9, 0xdfb9, 0x463f, {0xb2, 0xc5,0x71,0xee,0xc2,0x32,0xa6,0x9c}};

#define MYCOMPANYOP 0x10

#define MYCOMPANYDEBUG 0x0

EXTERN_C __declspec(selectany) const EVENT_DESCRIPTOR DNP_OP_EVENT = {0x1, 0x0, 0x10, 0x4, 0x0, 0x0, 0x8000000000000000};

#define DNP_OP_EVENT_value 0x1

EXTERN_C __declspec(selectany) const EVENT_DESCRIPTOR DNP_DEBUG_EVENT = {0x2, 0x0, 0x0, 0x4, 0x0, 0x0, 0x4000000000000000};

#define DNP_DEBUG_EVENT_value 0x2

#define MSG_SimpleMessage                0xB0000001L

Here, we have just renamed #define values.


Also, we have made some changes in EventLogging.Cpp as follows –

// EventLogging.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <windows.h>
#include <evntprov.h>           // ETW Publishing header
#include <winevt.h>             // EventLog Header.
#include "Manifest\manifest.h"
# pragma comment (lib, "wevtapi.lib")

int _tmain(int argc, _TCHAR* argv[])

{

 //first step - register the event

 REGHANDLE hPub = NULL;

 ULONG res = EventRegister(&MYCOMPANY_HPFS_PUBLISHER, NULL, NULL, &hPub);    

 if (ERROR_SUCCESS == res){
  _tprintf(_T("Event registered successfully\n"));
 }

 else{
  _tprintf(_T("Could not register event\n"));
 }

 EVENT_DATA_DESCRIPTOR opEventDesc;

 PWSTR pwsOp = L"HPFS : My Operational Event";

 EventDataDescCreate(&opEventDesc, pwsOp, ((ULONG)wcslen(pwsOp)+1)*sizeof(WCHAR));

 res = EventWrite(hPub, &DNP_OP_EVENT, 1, &opEventDesc);

 if (ERROR_SUCCESS == res){
  _tprintf(_T("Operational event successfully raised\n"));
 }

 else{

  _tprintf(_T("Could not raise operational event  Error = %i\n"), res);

 }

 EVENT_DATA_DESCRIPTOR debugEventDesc;

 PWSTR pwsDebug = L"HPFS : My Debug Event";

 EventDataDescCreate(&debugEventDesc, pwsDebug, ((ULONG)wcslen(pwsDebug)+1)*sizeof(WCHAR));

 res = EventWrite(hPub, &DNP_DEBUG_EVENT, 1, &debugEventDesc);

 if (ERROR_SUCCESS == res){
  _tprintf(_T("Debug event successfully raised\n"));
 }

 else{
  _tprintf(_T("Could not raise debug event.  Error = %i\n"), res);
 }

 EventUnregister(hPub);
      return 0;
}

Also we have made some changes to manifest.xml file as follows –

      <!--Publisher Info -->

      <provider name="MYCOMPANY-HPFS"
                   guid="{9CDE86C9-DFB9-463f-B2C5-71EEC232A69C}" 
                   symbol="MYCOMPANY-HPFS_PUBLISHER" 

resourceFileName="C:\Work_Shashi\EventLoggingCode\Debug\EventLogging.exe" messageFileName="C:\Work_Shashi\EventLoggingCode\Debug\EventLogging.exe">

        <!--Channel to which this Publisher can publish -->

        <channels>

          <channel chid="MyOpChannel" 
                             name="MYCOMPANY-HPFS/Operational" 
                             type="Operational" 
                             symbol="MYCOMPANYOP" 
                             isolation="Application" enabled="true"/>

          <channel chid="MyDebugChannel" 
                             name="MYCOMPANY-HPFS/Debug" 
                             type="Debug" 
                             symbol="MYCOMPANYDEBUG" 
                             isolation="Application" enabled="true"/>

        </channels>

Where "C:\Work_Shashi\EventLoggingCode\Debug\EventLogging.exe" this is my .exe address.

Now, we are getting Debug events properly. But, we are not able to get Operational events. We can see “Operational” tab but no event added in that.

Actually, our intention is to create a tab structure in Event viewer “Applications and Services Logs > MYCOMPANY > HPFS > Operational” and read and write operational events.

Kindly let us know what is the problem in our code.

Thank you.

With regards,

Shashikant
