You can simply drag and drop NOV components from the Visual Studio Toolbox. The Visual Studio Designer will automatically add the necessary dll references to your project and you can start coding directly. The following code snippet shows how to say "Hello World from Nevron Open Vision" using this type:

1. Drag and Drop the NLabelControl from the "Nevron NOV Controls" toolbox category to the main windows of your application.

2. Open the MainWindow.xaml file and make sure that the label control has a name:

<WpfControls:NLabelControl Name="nLabelControl1" HorizontalAlignment="Left" Height="100" Margin="192,131,0,0" VerticalAlignment="Top" Width="100"/>

3. Write the following code in MainWindow constructor:

using System.Windows;

namespace WpfApplication1
{
     /// <summary>
     /// Interaction logic for MainWindow.xaml
     /// </summary>
     public partial class MainWindow : Window
     {
         public MainWindow()
         {
             InitializeComponent();
             nLabelControl1.Widget.Text = "Hello World from NOV";
         }
     }
}

That's it - you have created your first WPF application using a NOV control. For more information check out the Integrating NOV from the Visual Studio Toolbox topic.

1. Create a new WPF project in Visual Studio

• From File Menu - Choose New Project
• Select the "Visual C# -> WPF Application" or "Visual Basic -> WPF Application"
• Click OK

2. Reference the NOV Assemblies

Ensure that your application references the following NOV dlls:

3. If your WPF application is for .NET Framework 5.0 or above, reference the Nuget package: System.Drawing.Common, version 5.0.0

4. Initialize the NOV Application

For C# WPF projects expand the App.xaml file in the Solution Explorer of Visual Studio and double click the App.xaml.cs file to open it. Then replace its content with the following C# code:

using System.Windows;

using Nevron.Nov.Barcode;
using Nevron.Nov.Chart;
using Nevron.Nov.Diagram;
using Nevron.Nov.Grid;
using Nevron.Nov.Schedule;
using Nevron.Nov.Text;
using Nevron.Nov.Windows.Wpf;

namespace NovWpfApplication
{
    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            // TODO: Apply license for redistribution here. You can skip this code when evaluating NOV.
            // NLicenseManager.Instance.SetLicense(new NLicense("LICENSE KEY"));

            // Install Nevron Open Vision for WPF
            NNovApplicationInstaller.Install(
                NBarcodeModule.Instance,
                NTextModule.Instance,
                NChartModule.Instance,
                NDiagramModule.Instance,
                NScheduleModule.Instance,
                NGridModule.Instance);
        }
    }
}

For Visual Basic WPF applications open the Application.xaml file and add the following attribute to the Application XAML element: Startup="Application_Startup". Then expand the Application.xaml file in the Solution Explorer of Visual Studio and double click the Application.xaml.vb file to open it. Replace its content with the following VB code:

Imports Nevron.Nov
Imports Nevron.Nov.Barcode
Imports Nevron.Nov.Chart
Imports Nevron.Nov.Diagram
Imports Nevron.Nov.Grid
Imports Nevron.Nov.Schedule
Imports Nevron.Nov.Text
Imports Nevron.Nov.Windows.Wpf

Class Application
    Private Sub Application_Startup(sender As Object, e As StartupEventArgs)
        ' TODO: Apply license for redistribution here. You can skip this code when evaluating NOV.
        ' NLicenseManager.Instance.SetLicense(New NLicense("LICENSE KEY"))

        ' Install Nevron Open Vision for Windows Forms
        NNovApplicationInstaller.Install(
                NBarcodeModule.Instance,
                NTextModule.Instance,
                NChartModule.Instance,
                NDiagramModule.Instance,
                NScheduleModule.Instance,
                NGridModule.Instance)
    End Sub
End Class

5. Say Hello World from NOV

For C# projects open the MainWindow.xaml.cs file and replace its content with the following code:

using System.Windows;
using Nevron.Nov.UI;
using Nevron.Nov.Windows.Wpf;
namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            // Add a NOV widget inside the window
            NLabel sayHelloWorldLabel = new NLabel("Hello World from Nevron Open Vision");
            Content = new NNovWidgetHost<NLabel>(sayHelloWorldLabel);
        }
    }
}

For Visual Basic (VB.NET) projects open the NMainWindow.xaml.vb file and replace its content with the following code:

Imports Nevron.Nov
Imports Nevron.Nov.UI
Imports Nevron.Nov.Windows.Wpf

Class MainWindow
    Public Sub New()
        ' This call is required by the designer.
        InitializeComponent()
        ' Add any initialization after the InitializeComponent() call.
        Content = New NNovWidgetHost(Of NWidget)(CreateNovContent())
    End Sub

    Private Function CreateNovContent() As NWidget
        Dim label As NLabel = New NLabel("Hello World from Nevron Open Vision")
        label.TextAlignment = ENContentAlignment.MiddleCenter
        Return label
    End Function
End Class

Run the application - it should display a simple form with a "Hello World from Nevron Open Vision" label inside.

This is as much as is required to host some NOV content in WPF. The sample just makes a simple label, as content of the NNovWidgetHost WPF Control, but this control can actually contain any NOV widget. See the UI Overview topic for an overview of the User Interface that comes along with NOV.
