Hello
I am new to WPF (first day today) , i have nice experience with windows forms with Vb , now i am starting wpf forms with VB (I dont know much XAML yet) but i feel like we can do all with code and drag and drop on form and changing properties
Q1] I learnt about doubleanimation class , but the animation i am making is not smooth , its flickering
it is code i am using for resizing form with animation , but it flickers a lot , its not smooth , (it looks a bit smooth if i increase animation duration to 7sec or more) i want to fix it
Q2] Docking and align , in vb we directly have a dock property , and even align which auto aligns labels and textbox to center of form when form is resized , here i tried using margin but i don't know what will be its margins in order to keep center when form is resized (i tried using properties but its not working in my case , i maybe doing something wrong ) , when i resize the label doesn't change place and get to center
my current form XAML code is
Q3] What a canvas is ? , why i need canvas to put more than 2 controls at same time ?
I deleted canvas and added a label , it got added , then i tried to add a button , the label disappears , like its deleted
Q4] can i import all the libraries that i could in normal Vb .NET 4.0 windows forms ?
Q5] Can i give glass effect (Gaussian blur ) to a full transparent form ? i tried but it doesn't seem to work , idk why but i could click even in back application through my form , like form doesn't even exist
Q6] What is that Storyboard thing ? can i use same with vb code ?
Q7] And can u tell me where i can learn manipulating WPF forms through vb code , not through XAML ? or i don't have a option and need to learn XAML?
Unrelated to WPF ] Q8] How can i permanent dock my application on desktop screen , like taskbar ?
Thank You

Code:
Private Delegate Sub Check()
Private Sub dropdown_MouseLeftButtonDown(sender As Object, e As MouseButtonEventArgs) Handles dropdown.MouseLeftButtonDown
Me.Background = New SolidColorBrush(Windows.Media.Color.FromRgb(64, 63, 63))
Dim t As System.Threading.Thread = New System.Threading.Thread(AddressOf Resize)
t.Start()
End Sub
Private Sub Resize()
If Me.Dispatcher.CheckAccess() = True Then
If Not Me.Height = sh Then
Dim da As New DoubleAnimation
da.From = 30
da.To = sh
da.Duration = New Duration(TimeSpan.FromSeconds(0.3))
Me.BeginAnimation(MainWindow.HeightProperty, da)
Else
Dim da As New DoubleAnimation
da.From = sh
da.To = 30
da.Duration = New Duration(TimeSpan.FromSeconds(0.3))
Me.BeginAnimation(MainWindow.HeightProperty, da)
End If
Else
Me.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, New Check(AddressOf Me.Resize))
End If
End SubQ2] Docking and align , in vb we directly have a dock property , and even align which auto aligns labels and textbox to center of form when form is resized , here i tried using margin but i don't know what will be its margins in order to keep center when form is resized (i tried using properties but its not working in my case , i maybe doing something wrong ) , when i resize the label doesn't change place and get to center
my current form XAML code is
HTML Code:
<Window x:Name="Main_Bar" x:Class="MainWindow"

<GradientStop Color="#FF020202" Offset="1"/>
</LinearGradientBrush>
</Window.OpacityMask>
<Window.TaskbarItemInfo>
<TaskbarItemInfo/>
</Window.TaskbarItemInfo>
<Canvas x:Name="canvas" HorizontalAlignment="Left" VerticalAlignment="Top">
<Label x:Name="dropdown" Width="625" Height="29" Background="#FF403F3F"/>
<DockPanel x:Name="dock1" Height="310" Width="625" HorizontalAlignment="Right">

</DockPanel>
</Canvas>
</Window>I deleted canvas and added a label , it got added , then i tried to add a button , the label disappears , like its deleted
