IE Programming --- DLL Binding
Gu Jianhui (http://solarsoft.126.com)
I have reviewed some information, but there are not many articles about the DLL binding of IE, and it is not very clear. To this end, I want to introduce this method:
Basic knowledge: VC COM, (Alt method)
The startup process of IE:
When the instance of IE is started, it will look for a CLSID in the registry, the specific location is
HKEY_LOCALL_MACHINE / SOFTWARE / Microsoft / Windows / CurrentVersion / Explorer / Browser Helper Objects
When there is a CLSID here, IE will establish an example of an object. For example: {B5D4581D-ED6A-4905-A267-25BAF7BE79C1} If this is not understood, you can find a book developed.
Development example:
VC established project, Alt Com appwizard Note is a DLL.
Establish a new class, must be Alt
In the menu, INSERT> New Alt Object: Simple Object
Modify and implement

The {B5D4581D-ED6A-4905-A267-25BAF7BE79C1} can be found in this file, pay attention, you do CSLID is definitely different.
Everything is OK, try it, you can first look at it, this project code
