Did you read this article from your last COM-related post? It goes into detail on how threads can be used for reading (and writing). Now your main UI thread can remain responsive.

hi, does anybody know how 2 add a 3DS object in VC++.
When the goin gets tough then tough gets going

It is not that easy. You have two solutions (that I see): either you go for yourself and write everything yourself. Everything means from loading the file (so, you have to know its format and everything) to displaying it.
This will be really long and difficult (and even more if you don't have experience).
Another option is to use a 3D engine (the ones that are used for free 3D games). But I don't know which ones support 3DS format, you'll have to search on google and compare some of them.

I might have a copy of the Max SDK lying around and some code that loaded models and processed them, it wasn't that hard. What are you trying to do?

Thanks for ur opinion..
But what I want to knkow is "Which Kernel Component is behind the scene for Event Logging process"? I mean how we can come to know that an event has occured without using the Event Viewer or using NotifyChangeEventLog() API?

Event Logging in Windows is works as a Windows Service. Run Services from Admin tool/control panal; U can see all services currently running in system. U can see a service called "Event Log", which write the events for windows.
See MSDN
BackupEventLog Saves the specified event log to a backup file.
ClearEventLog Clears the specified event log, and optionally saves the current copy of the logfile to a backup file.
CloseEventLog Closes a read handle to the specified event log.
DeregisterEventSource Closes a write handle to the specified event log.
GetEventLogInformation Retrieves information about the specified event log.
GetNumberOfEventLogRecords Retrieves the number of records in the specified event log.
GetOldestEventLogRecord Retrieves the absolute record number of the oldest record in the specified event log.
NotifyChangeEventLog Enables an application to receive notification when an event is written to the specified event logfile.
OpenBackupEventLog Opens a handle to a backup event log.
OpenEventLog Opens a handle to an event log.
ReadEventLog Reads a whole number of entries from the specified event log.
RegisterEventSource Retrieves a registered handle to an event log.
ReportEvent

Thanks for ur reply..
But I want to know how this mechanism of Event Logging is implemented internally in Windows Kernel? I dont want to use Event Viewer or NotifyChangeEventLog() API which helps me to identify when certain event occurs. Is there any way by which I can come to know about occurance of an Event??

How to execute a process virtually? That means without running an application i want to notify to OS that certain process is executed?
|
|
|
|

Thanks for reply..
Certain applications & Processes logs events to respective logs like Application, System and Security logs. So is there any way that without executing certain application, we can log the event on behalf of that particular application.
I know there APIs available for this task, but they dont allow to write in SECURITY LOGS, and my task is to write in Security Logs. So how can this be solved??

Ahh, Now that makes sense to me. Sorry for wasting your time as I don't know the answer to the new question.

Hi,
Im my dialog i use combobox to list all OPC servers.
Each tiem when i click "ListServer" button in my dialog..it displays all registered servers in combo box.
Iam using OPCEnum to get server list,the function is
int NumberOfOPCServers (BOOL UseOPCENUM, LPCSTR MachineName);
In that list there are also unwanted server list which i dont have any work in that is also displayed.
Is there any option to not display this kind of unwanted servers.

Hi,
In my MFC application i registered my server by using one clsid from GUID.exe as follows
SvrName = "EsimServer";
SvrDescr = "Prosimulator OPC Server";
UpdateRegistry ((BYTE *)&Svr_Clsid, SvrName, SvrDescr, HelpPath);
I gave clsid in top of my coding.
My problem is in same application i want to register different servers.
That is EsimServer1,EsimServer2,EsimServer3...
Can i do this by using the same clsid for all server register.
Anu

you have to use separate CLSID for each com component.
in this way u can register multiple servers
