Exceptions rule!

I’ve decided to revert to storytelling mode today.  So sit right back and you’ll hear a tale, a tale of my fateful trip (or click something useful- you’re the one deciding, and I’m the one typing to satisfy whatever inner demon has driven me to do

DDC starts in less than an hour

Plenty of good stuff for today- begin with Eliyas and Peter going over what's new in WDF for Windows 7 (or as we prefer to think of it WDF 1.9, since much of it also works all the back to Windows 2000 [KMDF] or Windows XP [UMDF]).  It continues later

Now for a different UMDF Coinstaller story...

This one can never affect you, so your blood pressure can start easing now.  It's just been a while since I tried to put on my "war stories" hat and tried tellin' one of them tales... In the Beginning was... the need to make sure drivers

So Nice I Tried it Twice

Yeah, the disco daze wuz good uns...  As long as I'm on the "Papa B Dumb" kick, I'll add a most embarrassing errata for WdfVerifier- this will be there in the official 6001 WDK, much to my eternal shame... With all the things to test on

Papa's "Wall of Dumb"

If memory serves correctly, always an iffy thing with us old fogies, Chloe Sullivan (on "Smallville") maintained a "Wall of Weird" covering all the strange events in her benighted hometown. So Papa's decided to inaugurate his "Wall

WdfVerifier tricks- Controlling DbgPrint on Vista and later OS

This is one you can use even if you never use WDF at all (of course, you may find WdfVerifier to be a bit annoying for such a use, but if you've got a memory like mine...). I wound up doing this a couple of days back, and thought it would make good fodder

Root causing a not reproducible KMDF installation issue- part 2: Not stupid, merely human

In the last installment, we had a workaround, so people could get on with their lives. BUT , there's still that problem of an access violation of unknown origin that happens every time we try to install KMDF 1.1 on a machine a continent or two away...

Working in the Windows Driver Frameworks QA department has its challenges. One of them for me has been that occasionally there is a paucity of the interesting problems that make for an intense workday. Since those are the days you write code or blog,
