CookieSpy is a custom explorer bar. This extension was created for the monitoring of cookie activity and for the possibility to add and edit cookies. I used VC++ 6.0 (SP4) and ATL.
1. At first, every IE band object must implement a couple interfaces:
I wrote a template class
DeskBandImpl<> to implement all the IE necessary routines.
2. Second, the band object must add to the registry the appropriate records to the "Component Categories" hive. I registered for CATID_InfoBand and CATID_CommBand categories. Certainly, you can use only one placement for band: vertical or horizontal at the same time.
3. Next, when IE calls
IObjectWithSite::SetSite method, the main objectives are:
- to create a band window.
- to advise
DWebBrowserEvents2 event sink interface for receiving event notifications from a explorer
CookieSpy::OnCreate method objectives:
- to create MSHTML control for displaying HTML page from resource
- to set external dispatch
5. By processing events:
NavigateComplete2, I try to update the cookie's information for the current document:
- to parse cookie string
- to update a main html page
6. Also the user can add and edit the cookie. If the cookie was stored on the hard disc, I try to find the cookie's file in cookie's folder for determining a expire date and domain\path info otherwise (in case lack of such file) I suggest that it's the session cookie.
Then with help
InternetSetCookie API I create a cookie for the specified URL.
I tested this band under Win2k and IE 5.0 only
Thanks a Neeraj Srivastava for his article "Implementing Web Browser Band Using ATL HTML Control"
