How to load HTML/JavaScript from embedded resource into winform web browser

Question

I want to have some HTML files with JavaScript loaded into the web browser control in a winforms (v2.0) application. During execution, I won't have internet access, so JavaScript and HTML forms will be embedded in he resources.resx file.

1) how can I load an HTML document out of the resource (analogous to a file:/// operation, but it isn't being loaded from the file system),

2) how would I declare the JavaScript scripts to be loaded? I.e.,

<script src=resource.jquery.min.js??? ... />

Thanks!

To load the HTML document, just compile your html file as embedded resource, and then:

WebBrowser browser = new WebBrowser();
browser.DocumentText = Properties.Resources.<your_html_file>;

If you really need to have external .js files, I think you will probably need to make them embedded resources. Then you can read these resources into a string of javascript.

string GetResourceString(string scriptFile) 
{ 
    Assembly assembly = Assembly.GetExecutingAssembly(); 
    Stream str = assembly.GetManifestResourceStream(scriptFile); 
    StreamReader sr = new StreamReader(str, Encoding.ASCII);
    return sr.ReadToEnd();
}

From here, look into IHTMLScriptElement. From what I understand, you may be able to use this javascript string and set it as the ITHMLScriptElement's text field. See this question

Good luck.
