Openwebkitsharp - COMException was unhandled?

Question

I am making a c# app that get a website I have and views it in the app. For this I am using OpenWebKitSharp to get the web view with HTML5. I followed all the instructions in the How-to-use.txt but, it runs with a popup saying it is not initialized and I should follow the How-to-use.txt. I am open to alternative as long as they can use HTML5.

My System:

Windows 10
Latest Visual Studio
Latest OpenWebKitSharp

using System;
using System.Windows.Forms;
using WebKit;

namespace Cosmic_Stocks
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            webKitBrowser1.UseJavaScript = true;

            Uri myUri = new Uri("http://cosmicsearch.org/stocks", UriKind.RelativeOrAbsolute);
            webKitBrowser1.Url = myUri;
        }
    }
}

The Popup:

The Popup Update:

Now there is a new error.

COMException was unhandled
AN unhandled exception of type 'system.runtime.interop.services.comexception' occored inopenwebkitsharp.dll

I got that when I was redoing the program

Could you post at least the code you already have? But my wild guess (without seeing your code) is that your missing a `new OpenWebKitSharp()` or something like that — Mathlight, Nov 28 '15 at 22:44
Than edit your question and insert the real piece of code. Without the actual code, nobody can / will help... — Mathlight, Nov 29 '15 at 13:56
Did you copy everything from the core folder inside the right build folder? — Mathlight, Nov 30 '15 at 16:36
I am still having this problem any solutions once I get 75 reputation I will add a bounty — arodebaugh, Dec 11 '15 at 23:52
Well, if you could provide a download link to the openwebkitsharp, i could take a look at it... — Mathlight, Dec 12 '15 at 09:23
Alright, maybe it's got to do something with the fact that the [Form.Load](https://msdn.microsoft.com/en-us/library/system.windows.forms.form.load(v=vs.110).aspx) function `Occurs before a form is displayed for the first time.` So my suggestion is to move everything off the method and put it in your Form constructor right after `InitializeComponent();`. But I'm not sure if that will work... — Mathlight, Dec 12 '15 at 14:07
Hmm... Maybe I will try that thank you I just do not have the computer with the code right now — arodebaugh, Dec 12 '15 at 14:09
Good luck. My guess is that because of that the screen isn't initialized, the Webkit browser isn't initializedalso. So I really hope for you that this is the problem. — Mathlight, Dec 12 '15 at 14:10
Testing that code right now it took me a long time too get time to test it — arodebaugh, Dec 28 '15 at 19:17
Following instructions worked for me. Let me know if you have questions or need any additional details. — jsanalytics, Dec 29 '15 at 03:09

Following How to use.txt instructions worked just fine:

Notes:

Windows 10
VisualStudio 2015 Community Edition
.NET 4.5.2
OpenWebKitSharp 3.0.1.0023

When adding project References to OpenWebKitSharp.dll and WebKit.Interop.dll, both files were selected from the open-webkit-sharp\Binary folder.

The same OpenWebKitSharp.dll from the open-webkit-sharp\Binary folder was added to Tools -> Choose Toolbox Items...

All files and sub-folders under open-webkit-sharp\Core and open-webkit-sharp\References were copied under bin\Debug folder of the target project.

The very same code as in your post was used:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        webKitBrowser1.UseJavaScript = true;

        Uri myUri = new Uri("http://cosmicsearch.org/stocks", UriKind.RelativeOrAbsolute);
        webKitBrowser1.Url = myUri;
    }
}
