Possible bug in transparent forms ?

[VBEdw]

Hello,

I am new to VB.NET,
how can I solve the problem with that edge ?

1 = Desktop BackGround
2 = Image in PictureBox (picture has transparent background)
PictureBox1 is in transparent Form
Form.BackColor = White
Form.TransparentKey = Transparent
I tried different colors in BackColor / TransparentKey, fruitless
+I can not put any picture DropShadow race that increases the pixels do not see any shadow
is Bug in Visual Studio or ?
There solving?
Sorry for English .

That's impossible to avoid in Windows Forms because it doesn't have partial transparency for individual pixels. But WPF does that brilliantly. I suggest you try the "shaped form" link in my signature below, because it gives you step by step instructions on how to use a WPF window with smoothed edges and a drop shadow. You don't need to know anything about WPF to follow it. The WPF window in the tutorial has a (WPF) button on it, but you could leave that out or add other WPF controls if you need them. If there's anything you don't understand, just ask here.

Hi BB,

this is result

nice a? is not nice, is perfect for me
and put your setup directly in cod

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="993.87" Width="899.436" WindowStyle="None" AllowsTransparency="True" Background="Transparent" VerticalAlignment="Center" HorizontalAlignment="Center">
    <Window.Effect>
        <DropShadowEffect x:Name="PrimeForm" BlurRadius="15" ShadowDepth="0" Opacity="0.7" Color="red"></DropShadowEffect>
    </Window.Effect>
    <Image Margin="92,227,87,46" Source="bgc.png" RenderTransformOrigin="0.5,0.5" VerticalAlignment="Center" HorizontalAlignment="Center" Width="720"/>
</Window>

but I still have a question,
can do in WPF project, all you do in VB project?
because I want to work only in WPF,
I am still in the beginning and I could go instead,
what advice you give me?
thank you for advice .

WPF is an alternative framework to Windows Forms. For practical tasks, it does everything Windows Forms does better. In particular, it supports animation and transparency in ways that Windows Forms does not, but that's barely scratching the surface. It's a big topic.
