Quick start for WinForms

This guide shows how to start working with DotNetBrowser and embed it in a simple WinForms application.

Before you begin make sure that your system meets software and hardware requirements.

1. Create a Windows Forms application

Create a new Embedding.WinForms WinForms Application C# Project or WinForms Application Visual Basic Project:

Winforms Project

2. Add DotNetBrowser to project.

In the Solution Explorer, right-click References and select the Manage NuGet Packages option:

Manage NuGet Packages

Choose “nuget.org” as the Package source, select the Browse tab, search for “DotNetBrowser”, select the DotNetBrowser.WinForms package and hit Install:

WinForms package

Accept license prompt to continue installation.

3. Change the source code

Insert the following code into the Form1.cs Form1.vb file:

using System.Windows.Forms;
using DotNetBrowser.Browser;
using DotNetBrowser.Engine;
using DotNetBrowser.WinForms;

namespace Embedding.WinForms
{
    /// <summary>
    ///     This example demonstrates how to embed DotNetBrowser
    ///     into a Windows Forms application.
    /// </summary>
    public partial class Form1 : Form
    {
        private const string Url = "https://html5test.com/";
        private readonly IBrowser browser;
        private readonly IEngine engine;

        public Form1()
        {
            // Create the Windows Forms BrowserView control.
            BrowserView browserView = new BrowserView
            {
                Dock = DockStyle.Fill
            };

            // Create and initialize the IEngine instance.
            EngineOptions engineOptions = new EngineOptions.Builder
            {
                RenderingMode = RenderingMode.HardwareAccelerated
            }.Build();
            engine = EngineFactory.Create(engineOptions);

            // Create the IBrowser instance.
            browser = engine.CreateBrowser();

            InitializeComponent();

            // Add the BrowserView control to the Form.
            Controls.Add(browserView);
            FormClosed += Form1_FormClosed;

            // Initialize the Windows Forms BrowserView control.
            browserView.InitializeFrom(browser);
            browser.Navigation.LoadUrl(Url);
        }

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            browser?.Dispose();
            engine?.Dispose();
        }
    }
}

        Public Sub New()
            ' Create the Windows Forms BrowserView control.
            Dim browserView As New BrowserView With {.Dock = DockStyle.Fill}

            ' Create and initialize the IEngine instance.
            Dim engineOptions As EngineOptions = New EngineOptions.Builder With {
                .RenderingMode = RenderingMode.HardwareAccelerated
            }.Build()
            engine = EngineFactory.Create(engineOptions)

            ' Create the IBrowser instance.
            browser = engine.CreateBrowser()

            InitializeComponent()

            ' Add the BrowserView control to the Form.
            Controls.Add(browserView)
            AddHandler FormClosed, AddressOf Form1_FormClosed

            ' Initialize the Windows Forms BrowserView control.
            browserView.InitializeFrom(browser)
            browser.Navigation.LoadUrl(Url)
        End Sub

        Private Sub Form1_FormClosed(sender As Object, e As FormClosedEventArgs)
            browser?.Dispose()
            engine?.Dispose()
        End Sub
    End Class
End Namespace

The complete project is available in our repository: C#, VB.

EngineOptions engineOptions = new EngineOptions.Builder
{
    LicenseKey = "your_license_key",
    RenderingMode = RenderingMode.HardwareAccelerated
}.Build();

Dim engineOptions As EngineOptions = New EngineOptions.Builder With {
    .LicenseKey = "your_license_key",
    .RenderingMode = RenderingMode.HardwareAccelerated
}.Build()
