Scripting Bridge

The ScriptingBridge is a utility which makes it possible to invoke JavaScript member functions in the embedded browser and to receive return values and objects. This is in contrast to the HtmlDocument.InvokeScript() method which can only invoke global functions. It also provides enhanced error handling by for example differentiating between a not found function and a function returning void.

Usage

If you for example want to invoke myObject.myFunction as defined in the following JavaScript snippet:

var myObject = {
	memberFunction: function()
	{
		return "some result";
	}
};

You can do so using the ScriptingBridge as follows where webBrowser is your System.Windows.Forms.WebBrowser instance:

var bridge = new ScriptingBridge(webBrowser, true);
var result = bridge.InvokeFunction<string>("myObject.myFunction", parameter);

Internet Feature Control

The InternetFeatureControl is a utility class which can be used to control features of the System.Windows.Forms.WebBrowser control.

Browser emulation

Using InternetFeatureControl.SetBrowserEmulation() the Internet Explorer rendering engine version can be controlled.

GPU acceleration

Using InternetFeatureControl.SetGpuRendering() GPU acceleration for rendering can be enabled and disabled.

WinInet Cache Control

The WinInetCacheControl is a utility class which can be used to controle the WinInet cache.

Using InternetFeatureControl.ClearCache() the WinInet cache can be fully cleared.
