75685408My two-hundred-and-seventh podcast is up. Charles Petzold wrote the book on Windows. Specifically, he wrote "Programming Windows, 1st edition" in 1988. This was the book I learned on and I still have it on my shelf. Charles has never stopped writing and is now working on a free book for Microsoft Press called "Programming Windows Phone 7 Series." I get the scoop from Chuck in this interview recorded in the waning hours of Mix 10 in Las Vegas.

Programmatically Detecting Screen Readers

March 25, '10 Comments [4] Posted in Programming | Windows Client

Tree View

I was installing the RC of Visual Studio 2010 yesterday and while the setup program ran I noticed the words CHECKED and UNCHECKED appearing in the Tree View.

I was thinking I'd found some cool bug, like I was peering into some background world where checkboxes announce their state with text or something. I dunno, it was late, don't judge! ;)

I asked a few people and someone said to to see if I was running a Screen Reader. Screen Readers are what the visually impaired use to find their way around interfaces. It's no at bug at all, it's helping me.

I ran a little program based on this chunk of code found here. I started using the structures found at PInvoke.NET but they were overkill. I didn't need six pages of constants.

[DllImport("user32.dll")]
static extern bool SystemParametersInfo(int iAction, int iParam, out bool bActive, int iUpdate);

public static bool IsScreenReaderActive()
{
int iAction = 70; // SPI_GETSCREENREADER constant;
int iParam = 0;
int iUpdate = 0;
bool bActive = false;
bool bReturn = SystemParametersInfo(iAction, iParam, out bActive, iUpdate);
return bReturn && bActive;
}

static void Main(string[] args)
{
bool retVal = IsScreenReaderActive();
}

Scandalously, the result was true. What? I am running a screen reader? Um, no.

Well, actually, yes. I give lots of presentations, sometimes just to one person looking over my shoulder so I run the Windows 7 Magnifier via the WinKey and PLUS hotkey. When the Windows Magnifier is running, I'm running a Screen Reader in that I'm running an accessibility assistant.

Interesting stuff. I like it when applications are paying attention and helping with accessibility.

Web Deployment Made Awesome: If You're Using XCopy, You're Doing It Wrong

March 24, '10 Comments [48] Posted in ASP.NET | IIS | Mix | Speaking
Sponsored By

Web Deployment Made Awesome: If You're Using XCopy, You're Doing It Wrong I did three talks at Mix 10 this year, and I'm going to do blog posts for each one, sharing what I talked about and some code if it's useful.

I did a talk on Deployment called "Web Deployment Made Awesome: If You're Using XCopy, You're Doing It Wrong."

You can download the talk here, or watch it online:

VIDEO Download: MP4 Video, Windows Media Video, Windows Media Video (High)

I always try to sneak cooler titles into conferences if I can. It's better than "WEB101: Deploying Websites using Microsoft Visual Studio 2010's WebDeploy OneClick Publish Wizard Super Karate Monkey Death Car September CTP R2." Well, maybe not way better, but still.

imageHere's an outline of what Deployment Related topics I tried to cover

  • Web Packaging - Offline vs. Online
    • From VS 2010
    • From IIS Manager
  • Web.Config Transformation
    • Transform Syntax
    • Locator Syntax
    • Why not XSLT?
  • Deploying
    • Command Line
    • What If Switch
    • From IIS
    • Content Sync
  • DB Deployment
    • Scripting Source DB
    • Adding custom SQL Scripts
  • Download and Deployment of Open Source
    • Web PI
    • App Gallery
  • One Click Publish
    • Using Web Deploy (Ms Deploy) WMSVC
    • Using Web Deploy (Ms Deploy) Remote Agent
    • Using InProc Web Deploy (Ms Deploy)

Here's some cool highlights about WebDeployment in Visual Studio 2010. You can right-click on your web.config and click "Add Config Transforms."

When you do this, you'll get a web.debug.config and a web.release.config. You can make a web.whatever.config if you like, as long as the name lines up with a configuration profile. These files are just the changes you want made, not a complete copy of your web.config.

You might think you'd want to use XSLT to transform a web.config, but while they feels intuitively right it's actually very verbose.

Here's two transforms, one using XSLT and the same one using the XML Document Transform syntax/namespace. As with all things there's multiple ways in XSLT to do this, but you get the general idea. XSLT is a generalized tree transformation language, while this deployment one is optimized for a specific subset of common scenarios. But, the cool part is that each XDT transform is a .NET plugin, so you can make your own.












NewSetting
New Setting Value



Or the same thing via the deployment transform:





Now, to express this concretely, here's my new NerdDinner web.debug.config:










and here's the web.release.config. Note that I update connectionStrings, change appSettings (in this case, Twitter library stuff), and change the system.web section, turning on customErrors and removing the debug attribute.













xdt:Transform="SetAttributes" xdt:Locator="Match(key)" />
xdt:Transform="SetAttributes" xdt:Locator="Match(key)" />




xdt:Transform="Replace">





This is just config transforms, which is a small part of the whole deployment process. I also showed the packaging process and the package deployment that can happen with one-click from within Visual Studio, or can be initiated from IIS, or at the command-line from your Continuous Integration solution.

The WebDeploy packaging and deployment solution is also what the Web Platform Installer uses. It's all the same engine. This screenshot is me importing an open source application directly from a zip file. Note it's more than just what files to use, it's also setting ACLs (Access Control Lists, or permissions) and creating an IIS application. This just scratches the surface.

Check out my talk, I hope it helps you out. There's more content in that 60 min talk than I could easily put in a single blog post.

Windows Phone 7 SeriesMy two-hundred-and-sixth podcast is up. I was at Mix last week in Las Vegas, and got a second to sit down with Charlie Kindel from the Windows Phone team. What's the real developer story? What can these phones do and how do we program them? We talk aesthetic, controls, IDEs and hardware details.
