i'm pretty new on powershell and noob on GUI. I try to make a GUI working with powershell Windows 7 with powershell V2

Here is my xaml code

<Window x:Class="WpfApplication1.MainWindow"

    </Border>
    <CheckBox x:Name="checkBox_Copy" Content="PDF Creator" HorizontalAlignment="Left" Margin="6,236,0,0" VerticalAlignment="Top" Checked="checkBox_Checked"/>
    <CheckBox x:Name="checkBox_Copy1" Content="VPN Client" HorizontalAlignment="Left" Margin="6,306,0,0" VerticalAlignment="Top" Checked="checkBox_Checked" RenderTransformOrigin="0.504,3.382"/>

    <Button x:Name="button" Content="OK" HorizontalAlignment="Left" Margin="115,12,0,-22" Grid.Row="3" VerticalAlignment="Top" Width="75" Click="button_Click"/>
    <TextBlock x:Name="textBlock1" HorizontalAlignment="Left" Margin="42,113,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="404"><Run Text="Sélectionn"/><Run Text="ez"/><Run Text=" "/><Run Text="les applications à installer et appuyez sur OK"/></TextBlock>
    <Button x:Name="button1" Content="Annuler" HorizontalAlignment="Left" Margin="263,12,0,-22" Grid.Row="3" VerticalAlignment="Top" Width="75" Height="22"/>
    <TextBox x:Name="textBox" HorizontalAlignment="Left" Height="23" Margin="10,0,0,0" TextWrapping="Wrap" Text="Suggestion de programmes" VerticalAlignment="Top" Width="278" Grid.Row="2"/>
    <Button x:Name="button2" Content="Envoyer" HorizontalAlignment="Left" Margin="311,1,0,0" VerticalAlignment="Top" Width="75" Grid.Row="2"/>

</Grid>
</Window>

i changed x:name by name i deleted x:Class="WpfApplication1.MainWindow"

here's the error

    Exception lors de l'appel de « Load » avec « 1 » argument(s) : « XmlNamespace, Assembly ou ClrNamespace absent de l'ins
truction Mapping. Ligne '0' position '0'. »

i deleted four lines: xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:local="clr-namespace:WpfApplication1"

mc:Ignorable="d"

Another error :

    Exception lors de l'appel de « Load » avec « 1 » argument(s) : « Compilation obligatoire du fichier XAML qui spécifie l
es événements. Ligne '0' position '0'. »
Au niveau de STOREEUROPE_ALEX_STORE.ps1 : 39 Caractère : 40
+ $Form=[Windows.Markup.XamlReader]::Load <<<< ($reader)
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException

        + CategoryInfo          : InvalidOperation: (ShowDialog:String) [], RuntimeException
        + FullyQualifiedErrorId : InvokeMethodOnNull

there are no events on my buttons, i just want to display my form first.

Can you help me? thank you very much.

Made some changes for you in your XAML code. You can't specify Event actions in the XAML like you would with C# using PowerShell. I saw errors with Click (for buttons) and Check (for Checkbox) events that were in the XAML code. These should be handled after you have loaded the XAML.

Note my comments in the code example regarding loading the controls and handling the events
