Documentation for this section has not yet been entered.
System.Windows.Forms.HtmlDocument is a wrapper for the Internet Explorer Document Object Model (DOM), which is written in COM. If you need to access unexposed properties or methods on the underlying COM interfaces, such as IHTMLDocument2, you can use this object to query for them.
To use the unmanaged interfaces, import the MSHTML library (mshtml.dll) into your application. However, you can also execute unexposed properties and methods using the IDispatch::Invoke method.
