How can I enable editing for the WebBrowser?

You can set the content editable by getting a reference to a IHTMLElement3 element and initializing the contentEditable property with ‘true’.

	
	private void EnableEditing()
	{
		IHTMLDocument3 doc = (IHTMLDocument3) browser.GetDocument();
		if (doc != null)
		{
			IHTMLElement3 el = (IHTMLElement3) doc.GetBody();
			el.contentEditable = 'true';
		}
	}

If you want to read out contents of a specific element use an id in the html source:

	
	<span id='EditText'>EditableText</span>

From CSharp you can reference this text with

	
	IHTMLElement3 el = (IHTMLElement3) doc.getElementById('EditText');
	MessageBox.Show(el.GetInnerText());
	MessageBox.Show(el.GetInnerHTML());

You can use IHTMLDocument3 and IHTMLElement3 interface definitions from the imported type library dll C:\Program Files\Microsoft.NET\Primary Interop Assemblies\Microsoft.mshtml.dll
