I don't have access anymore to the computer (school) I used at the time!

This is a question for Google: there are many papers, tutorials and samples to be found.

You can always include the font as a content item. All you need to do is make sure that the font is available in the application directory. If you do this, you can then reference it like this: <Label FontFamily="#Digital-7" Content="Have a nice day!" /> This space for rent

Did you study the documentation? ChangeDisplaySettingsEx function (Windows)[^] The difficult we do right away... ...the impossible takes slightly longer.

You seem to be missing the most important part - the actual error message. "These people looked deep within my soul and assigned me a number based on the order in which I joined." - Homer

It doesn't work better. Well, I had posted a simple code, hoping that it would be more clear for users to help me...but I'm afraid that I'd better post something very similar to my actual code..if I want the problem to be clearly exposed...and help you to try to help me ;-) There's a sound class, called UISound: Imports System.Threading Public Class UISound Dim writingPath As String = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) & "\_UI Sounds\" Public Shared WithEvents uiPlayer As New WMPLib.WindowsMediaPlayer Public Shared uiThread As Thread = New Thread(AddressOf ReceiveSound) Public Shared Sub ReceiveSound(ByVal url As String) uiThread = New Thread(AddressOf PlayFile) uiThread.Start(url) End Sub Public Shared Sub PlayFile(ByVal url As String) uiPlayer.URL = writingPath & url uiPlayer.controls.play() End Sub End Class The sound is called from a sub in the MainWindow...which itself fires other subs in cascade that involve a heavy compute time: Sub one() UISound.ReceiveSound("sound1.wav") Dim a As Integer = 0 For i As Integer = 0 To 999999999 a = i Next Two() End Sub Sub two() Dim a As Integer = 0 For i As Integer = 0 To 999999999 a = i Next Three() End Sub Sub Three() Dim a As Integer = 0 For i As Integer = 0 To 999999999 a = i Next End Sub It appears that the sound is played after the whole "cascade" is runned, so after Sub Three() End. If you try this code you will verify that inserting System.Windows.Forms.Application.DoEvents() after uiPlayer.controls.play()...doesn't work better Thanks for your help!!

It'd (probably) be faster to get the list once and filter it. Since GetFiles already returns an array, there's no need to convert it. Bastard Programmer from Hell :suss: If you can't read my code, try converting it here[^]

if your application is WPF application you can load a physical file Imports System.Windows.Markup Class MainWindow Private Sub Window\_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Dim objXaml = XamlReader.Load(IO.File.Open(Environment.CurrentDirectory & "Resource\\theme.xaml", IO.FileMode.Open)) End Sub End Class if it was a silverlight application you cant do that :( ...

I'm not really an XPath expert, but my guess would be: //System[1]/Kind

The direct binding may have it's uses but I only ever do LOB apps and there is always a database sitting behind the app. I have trouble envisioning an app without a database :-O Never underestimate the power of human stupidity RAH

Thanks for your reply! No, that's not what I mean (sorry english isn't my mothertongue) I mean, being able to select the radio button which has the focus, with the key "A" instead of the default "SPACE" key!

You need to look into using Process.Start[^]. I'm not a stalker, I just know things. Oh by the way, you're out of milk. Forgive your enemies - it messes with their heads My blog | My articles | MoXAML PowerToys | Onyx
