Hi guys... I'm just starting with Windows 8/Metro... I'm trying to figure out how to get a list of drives on the machine. The MSDN says Environment.GetLogicalDrives should work or System.IO.Directory.GetLogicalDrives but I can't seem to find either. I assume the framework for Metro apps is limited similar to how Silverlight is a subset of the .Net libraries... Anyone have any idea how to do this?

You cannot enumerate drives using the WinRT APIs. You only have access to isolated storage or you can use the open/save file dialogs to allow the user to browse for a file/folder.

Have a button in the UI, called 'btnCapture' and an image called 'imgPhoto'
In the click event of this button, have the following code. Also, make the click event async.

private async void btnCapture_Click(object sender, RoutedEventArgs e)
{
   CameraCaptureUI dialog = new CameraCaptureUI();
   StorageFile file = await dialog.CaptureFileAsync(CameraCaptureUIMode.Photo);
   if (file != null)
   {
     BitmapImage bitmapImage = new BitmapImage();
     using (IRandomAccessStream fileStream = await file.OpenAsync(FileAccessMode.Read))
     {
       bitmapImage.SetSource(fileStream);
     }
     imgPhoto.Source = bitmapImage;
   }
}

In case of system resource access, Metro Apps work in the same way as Silverlight. So you need to explicitly provide access for the application to access Webcam and Microphone. You can give this permission in Capabilities tab of Application Manifest.

Just learning experimenting with WinRT..

I can see you can mix and match C++ and C# WinRT component, they feel like being in the "same realm"..

But how do I mix with Javascript/HTML component?

Say I have a normal DirectX C++ WinRT app, with some AI in C# and I want to show some information text panel with lots of interactive rich text, a job for Javascript.
How do I show the Javascript/HTML in my XAML app?
Further, ideally, I'd like to use some of my 'business data' to customize the text / HTML, any sample?

A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

I have not tried this. I think you could style a WebView to resemble the rest of your application. Then arrange the html, css and javascript to present the data.

Hope this helps!

If you found a different workaround, I would love to hear about it.

essay/interview on Flash in IE10 in Win8 about which there has been a lot of confusion among developers

Ashish G. of MS wrote: "As the flash is integrated with Internet Explorer 10 and does not comes as plug-in, it should work on both – Desktop and Metro version of Internet Explorer."[^].

As example of the confusion: Tim Anderson's blog writing about an interview with Scott Guthrie[^]. Do note the wild diversity, and contradictions, in the various readers' comments.

One wonders if integrating Flash is, on a primary level, an anti-iPad/Apple geo-political move; but one might ask: why not SilverLight; unless one claims, as some responders to the article above do, that WinRT + XAML is "SilverLight 6."

IE10 on Metro and WinRT supposed to be the "no plug-in" browser, so MS emphasized in various public statements, so I thought.

I remain confused about whether on ARM hardware in Win8, other browsers, other than IE10 will be usable.

All attempts at un-confusing me are appreciated Smile | :)

thanks, Bill

IE10 for Desktop suffers no changes. You can have any plug-in on it!.

In Metro you cannot install any plugin. It's not supported. So, the IE10 for metro have silverlight & flash plugins built-in. For security or compatibility reason may be.

Good point of view from you =)
