I am very new to the I3C protocol, and do not have a clear understanding of the terms Command and Event.
Could anyone help me explain these, probably with some use cases.
Thank you!

I'm troubleshooting performance because of users complaining of low FPS & I seem to be getting this warning and any attempts to trace it leads me to HERE's built-in functions.
I think I understand what it means, and perhaps it's not the root of the problem, but it's my only lead.
Other than that the project is applying everything from HERE's 'Best Practices' doc.
Also, any tips that can help improve performance are GREATLY appreciated.
Thanks!
I'm currently developping a miniFilter driver from scratch.
Right now i'm just trying to understand how all of this works, which actions leads to which IRP event etc...
After some tests with the miniSpy filter Driver, I can see those 3 Major operation and can't figure out what is done.
IRP_MJ_ACQUIRE_FOR_SECTION_SYNCHRONIZATION
IRP_MJ_QUERY_INFORMATION
IRP_MJ_RELEASE_FOR_SECTION_SYNCHRONIZATION
I'm usually using this link : https://msdn.microsoft.com/en-us/library/windows/hardware/ff548630(v=vs.85).aspx
But I can't found ACQUIRE/RELEASE_FOR_SECTION_SYNCHRONIZATION.
Can someone explain me what they mean ?
First of all you might want to check this out.
You can think of the IRP_MJ_ACQUIRE_FOR_SECTION_SYNCHRONIZATION as callback for CreateaFileMapping. It essentially tells you that the FILE_OBJECT in question is about to have section object created for it.
IRP_MJ_QUERY_INFORMATION its the file-system callback for ZwQueryInformationFile. Check that one out for more details on various information classes and what structures are behind each buffer for each class.
IRP_MJ_RELEASE_FOR_SECTION_SYNCHRONIZATION has no parameters. Consider it as an equivalent of CloseHandle(SectionHandle). Check this.
Hope it clears things out.
Good luck.
I am working on creating a Control Framewrok using Informatica.
I am maintaining a list of all the files to be loaded in a relational table.
For a particular type of file, I wish to initiate a different mapping.
How should i go about doing this.
Help/ Pointers will be greatly appreciated.

Use router transformation.
Took some time to figure this one out.
Thanks anyway. Hope this helps someone else. :)
.NET has several built in Perfmons, and I would like to know is it possible to extend one of the built in ones and add custom functionality.
More specifically, I would like to take RateOfCountsPerSecond32 and make it be something such as RateOfCountsPerMinute. Basically I would like to be able to monitor the average number of events that happen in a given time, but longer than a second.
Is extending the right idea? If so does anyone have a quick syntax example of how it can be done? I have read that it can be done but documentation is super poor on the subject. Or is there a better way to go about this entirely, very open to suggestions.
Thanks for any help,
I'm looking for a programming that monitors my activity in Windows Vista/XP/2003 that lets me know what commands, shortcuts, web sites, etc. I visit more frequently.
with this information I could create shortcuts, hotkeys, aliases, etc to increase productivity, as time goes on I could know how much time I saved in comparison to other days.
Leon Bambrick's time snapper is pretty interesting. May not be exactly what your looking for though. http://www.timesnapper.com/
There's a program called Rescue Time which monitors your applications and website usage.

I have a program like that and have used it for years. It's called laziness. When I get tired enough of doing the same thing over again, I write a program or script to do it for me.
Not exactly a tool to record your activity, but Tasktop might help you achieve what you want.
I use Mylyn, Tasktop little bother, in eclipse to organize and keep me focused in my tasks, and it's a great help.
