I would like to set the InitialDirectory property of a WindowsAPICodePack CommonOpenFileDialog to My computer Location, I did it using the equivalent CLSID or GUID or what the hell is that, just I would like to know if exist a more native/safe way to correctly set the My computer location, I've tried this but didn't worked:
.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyComputer) 
This is the code that I'm using:
Dim FolderPicker As New Microsoft.WindowsAPICodePack.Dialogs.CommonOpenFileDialog
With FolderPicker
    .IsFolderPicker = True
    .Title = "Folder Dialog Test"
    .InitialDirectory = "::{20D04FE0-3AEA-1069-A2D8-08002B30309D}" ' My Computer
    .DefaultFileName = "C:\"
End With
UPDATE:
I'm on Windows 8 x64.
The other special folders such as libraries and desktop works like this:
.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) 
				
                        
Environment.GetFolderPath never returns a path for MyComputer since there isn't actually a path for it.
From the MSDN documentation:
This means that your solution is the best available (and likely one that not too many people are aware of). For future interest, here is a link to the list of available CLSIDs.
