Steve S25-Jul-06 22:14 Steve S 25-Jul-06 22:14  Typically, your thread will loop continuously, with checks to see if (a) the current read has timed out, in which case you continue, or (b) an event was trggered (See CreateEvent in the API docs), in which case the thread exits. That way, you can trigger the event in your main thread when you want to quit the app, and then wait in the main thread for the comms thread to exit. You can combine the two by using COMMS events and waiting until either a received character is available or the other event was triggered, and acting accordingly. P.J.Naughter has written some excellent classes, one of which deals with comms ports, so check that out in the MFC/C++ libraries section here on CP. Steve S Developer for hire Re: Thread?! David Crow27-Jul-06 2:57 David Crow 27-Jul-06 2:57  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. "Money talks.

When the goin gets tough then tough gets going Re: 3d max object Hamid_RT25-Jul-06 20:12 Hamid_RT 25-Jul-06 20:12  See http://www.wotsit.org[^] WhiteSky Re: 3d max object Cedric Moonen25-Jul-06 20:38 Cedric Moonen 25-Jul-06 20:38  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.

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? Re: Events Anilkumar K V25-Jul-06 21:08 Anilkumar K V 25-Jul-06 21:08  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 Re: Events joshiprashant25-Jul-06 23:41 joshiprashant 25-Jul-06 23:41  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?? Executing Process Virtually joshiprashant25-Jul-06 19:31 joshiprashant 25-Jul-06 19:31  How to execute a process virtually? That means without running an application i want to notify to OS that certain process is executed? Re: Executing Process Virtually John M. Drescher25-Jul-06 21:11 John M. Drescher 25-Jul-06 21:11  How would this help? I don't believe any windows os keeps any tracking info on if a program has ran so what would this add?? Please correct me if I am wrong... John Re: Executing Process Virtually joshiprashant26-Jul-06 0:15 joshiprashant 26-Jul-06 0:15  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?? Re: Executing Process Virtually John M. Drescher26-Jul-06 11:36 John M. Drescher 26-Jul-06 11:36  Ahh, Now that makes sense to me. Sorry for wasting your time as I don't know the answer to the new question.
