I want to modify HTTP requests headers using an Internet Explorer Browser Helper Object.

Hello! I've written two objects, a deskband toolbar and a bho for IE. The goal is that the bho shows up the toolbar after installation. Microsoft's approach is to use pBrowser->ShowBrowserBar(&vtBandGUID, &vtShow, 0); This method is nice to show and hide toolbars which got already activated via the addon manager but does not work for d...

I have a BHO that is supposed to intercept the DISPID_BEFORENAVIGATE2 events when Windows Explorer is browsing the local disks. It works well in XP and Vista, but stopped working in Windows 7 RC.

I have a CDHTMLDialog running in IE that has a fixed size that I chose, and runs in a fixed window to match this size. My problem is that the user can zoom on it (by ctrl-mousewheel) causing my html to be larger or smaller than the window which looks awkward and adds annoying scrollbars. Also, the user might use ctrl-+ or ctrl-- to cha...
I have a CDHTMLDialog in a BHO that I want to be partially transparent, in the sense that the transparent area changes according to the logic of the dialog.

How would I handle when the window moves? I've also trie...

A goal is to attach handlers as soon as the user can be...
