Where have you been?!

Well, as you could probably guess, I haven’t had much to say for a while for a couple of reasons – first and foremost, the Windows 8 product cycle was really intense.  A lot of changes under the hood came down the pipe, so with the big additions to WDF (UMDF especially) we really had a ton of work to do!  Secondly I really couldn’t talk…

You’ve had the time, let’s hear the feedback.

I hope those of you who are using the new Visual Studio 2011 with the WDK integration are having some fun, even if it’s just been wandering around and playing.  What, if anything, are you not liking about it?  Anything that’s unintuitive or confusing?  What do you like about it, but would like to maybe…

Well, you can kind of see why we’ve been quiet around here…

  If you’re watching what’s going on at //BUILD (and why wouldn’t you be?), you may have seen that UMDF now supports hardware access (via ports and registers) and interrupt handling!  If you haven’t seen it, you can go read more here. And the other big one.  Something I’ve been begging to get done for…

It’s okay to assert yourself, just be careful how forcefully you do it. (Op. Ed.)

We recently had a good discussion internally about the nature of ASSERTs in code.  I, being the rebel that I am, took the time honored stance of, “if you’ve hit it, you’ve triaged it and changed to code to handle that condition gracefully (at least as gracefully as possible), it’s safe to remove that assert.”  …

And here you thought I had a cloaking device

Got a good one to share with the group; Q: Can I make a kernel mode driver that opens a handle and talks to a UMDF based driver in another device stack? A: Why yes you can!  Quite simply done provide you follow all the rules. This is a variant of the UMDF initiated cross…

House cleaning

The fourth part of Abhishek’s online UMDF debugging tutorials is up now. 🙂 http://www.microsoft.com/whdc/devtools/debugging/umdftraining.mspx Next up, those of you playing with Windows 7 may have noticed that the “Found New Hardware” wizard is gone!  This in itself is not that big a deal, but it does mean that some of the WDK sample installation instructions…

Intellisense, the Musical part 3

Like all good stories, sometimes the 2nd act is the hardest to follow.  In this case it was simply a matter of other things coming up rather than writers block. 🙂 What kicked me in the rump to get this next part up was a few more questions about driver writing, WDK integration into Visual…

Genuine UMDF filtered drivers

Filter drivers have come up in conversations recently (both internal and external), so I wanted to take some time here to address some of the issues that were brought up with regards to UMDF filter drivers and how to make them.  Note: I’m not going to cover all the configuration dynamics available for UMDF filter…

Think globally, lock at the smallest scope possible.

Yes, I know that’s a rip off of a ThinkGeek shirt (which I own). Well, this is going to be my second post on this topic (okay, third), but as it managed to rear its head again recently, what better time to blog.  And I’m going to also blog it simply to prove to Doron…
