Int GetSite( ref Guid guid, out IntPtr ppvSite) InterfaceType(ComInterfaceType.InterfaceIsIUnknown),
Callers can also get the latest site passed to SetSite by using GetSite.Īdd references and imports to the following components: By using IObjectWithSite, a container can pass the IUnknown pointer of its site to the object through SetSite. This interface should only be used when IOleObject is not already in use. The IObjectWithSite interface provides a siting mechanism. Outside of IOleObject::SetClientSite, there is no generic means through which an object becomes aware of its site. Often, an object must communicate directly with a container site that is managing the object. The IObjectWithSite interface provides simple objects with a lightweight siting mechanism (lighter than IOleObject). Now you have to define the IObjectWithSite interface which the BHO class will implement. In order to do that, we must implement the IObjectWithSite interface. Such a module can get in touch with the browser through the container's site.

You can use F2 on the CS file in the Solution Explorer.įrom this high-level overview of Browser Helper Objects, one concept emerges clearly: a BHO is a dynamic-link library (DLL) capable of attaching itself to any new instance of Internet Explorer and, under certain circumstances, also Windows Explorer. Open MS Visual Studio 2010 and create a new project "Visual C#" -> "Windows" -> "Class Library" named "IEPlugin"Ī new project is opened for you containing a single class Class1. NET C# as a programming framework and language.

I will explain here a step by step guide on how to accomplish this task as it is better to learn how to do it instead of just take a ready solution which you don't know how it works, and the moment you touch something to make it suit your needs, it breaks down and you have no idea why. To achieve that, you need to develop a custom IE plug-in using BHO that will track user browsing activities and display your discounts based on some content keywords filtering.
You want to develop an Internet Explorer extension which shows some fixed layer containing promotional offers and discounts for the goods you are selling. For example, a BHO might highlight terms of interest to the user, such as addresses.įor more background information, see. Beginning with Internet Explorer 5, this feature allows developers to add entries into the Tools menu and buttons to the toolbar.Ī Browser Helper Object (BHO) runs within Internet Explorer and offers additional services, often without any obvious user interface. Introduced in Microsoft Internet Explorer 4.0, this feature enables developers to create Explorer Bars and add entries into the standard context menus. Backgroundīrowser extensions allow developers to provide easy access to their browser enhancements by adding elements (like an Explorer Bar) to the default user interface. In this article, I will explain how to inject new static and dynamic content into an existing webpage.
