I am a newbie working towards developing an IE extension that would appear as an overlay in certain webpages. I am getting started by creating a simple BHO in VS2008 (using C++), but I am wondering how UI may be incorporated within the project. Any ideas?
Just to give you an idea, I'm looking for overlays similar to what was developed by stickis

Thanks
You have two real options:
1> Inject your UI into the page as HTML.
2> Overlay your UI (using Windows graphics APIs) over top of the page.
Neither of these is super-simple, I'm afraid. Unfortunately, doing UI is usually the hardest part of building IE addons.
The key question is whether you need a BHO at all. Between context-menu extensions and IE8 Accelerators, you may find that you can let IE do all of the heavy lifting. See www.enhanceie.com/ie/dev.asp for more info.
Using CreateWIndowEx() was what I was looking for :)

Are the any alternatives how to display PDF/HTML file in the MFC based application without using ActiveX elements like CHtmlView?
Thanks in advance.
The alternative would be WebView2. It uses the Microsoft Edge (Chromium) browser engine, unlike CHtmlView that's based on IE.
If the reason you are looking for an alternative is, that you need a more up-to-date browser implementation, then WebView2 delivers. If, on the other hand, you are looking for an alternative, that's easier to use, then not a whole lot changes. Either one expects very intimate familiarity with COM and C++.
I'm looking for suggestions on technologies to design a windows UI that's powered by HTML. I've run across HTMLayout which seems pretty good if not perhaps a bit limited. Are there any other technologies that would provide a good platform for creating an application UI based on HTML?
You could use chromiumembedded. You get the power of Google's Chrome in your application.
Evernote used CEF (Chromium Embedded Framework) when they moved from C# back to C++.
Unlike HTMLayout, CEF has a permissive license, which allows usage in commercial applications without paying royalties. The drawback would be the huge binary size.
Qt has the ability to use CSS to layout ui and some other cool things. MSHTML namespace and COM interfaces allow for some ui styles as well. That's all I know of off the top of my head for C++
Windows 8 when released will provide some sort of API using HTML5 and JavaScript for tile based applications in the start screen.
There is some libraries that lets you run C++. So, it is it possible to run a game that uses directx full mode screen?
Google is developing a tool to allow this kind of thing via Chrome. It is called Chrome Native Client, or NACL for short. http://blog.chromium.org/2010/05/sneak-peek-at-native-client-sdk.html
In general, no. Most online games are written with Javascript, Flash, the newly hatchedd HTML5 and similar technologies. Perhaps C++ integration is possible on some level, but you definitely cannot write a browser-hosted game purely and entirely in C++.
it could also be done with an ActiveX control. ActiveX only works in IE. there are Netscape plugins that work in other browsers. so make a solution that contains both. you need a book on ActiveX/COM/OLE. Better yet, take a class if you can find one, you will learn far more, because COM is not an easy subject to just read about and then really do - versioning is a big problem.
nope, not supported in firefox. but read this: http://www.google.com/chrome/intl/en/webmasters-faq.html#activex
some people may have activex controls disabled. if this is the case, your game will not run. you will have to tell the user that they will need to change their security settings in IE. you can get feedback from the object element in javascript as to whether or not the activex loaded. there is code out there for that.

examples are all over the internet.
I know this has been asked twice before but both had no proper replies and are dated so in case someone has found something in these days, I'm asking again!.
Any one knows any good tutorial for MSHTML or some open source project which can be read to understand how various operations can be done in MSHTML - MFC?
Thanks
Your question makes it difficult to know exactly what you are trying to do, but the main MFC class that you need to use is CHtmlView. The MSDN has the definitive sources of information about it:
CHtmlView class
Creating a Web
Browser-Style MFC Application
Using MFC to Host a WebBrowser Control
If you find those links a bit terse, then this page contains some slightly friendlier articles:
Advanced CHtmlView Hosting
However, I would also ask whether you are definitely 100% sure that you want to use MFC?
The reason I ask is because I've worked for a number of years on an open-source project that hosts the Microsoft WebBrowser control and we saw significant performance improvements when we stripped out MFC from the project. The MFC abstractions weren't really buying us anything over the COM interfaces that are exposed by the control. Stripping out the MFC also made our code much simpler.
The project is open source, so if you want to see the code for yourself, you can get more information here. It is specifically the LibRender project that hosts the WebBrowser control. If you want to see it running, you should build the SWViewer solution.
The one place I like to visit for MFC is Newcomer's site There are some useful tutorials and demos of various things there. Although its more of a general MFC site, so maybe you can find what you are looking for there.
How do I make a Web Browser toolbar in C++.
in dev-C++ for I.E with no addon libraries?
Since you use Dev C++ I am assuming you want to make IE Addons?
If thats the case, this should get you started:
Creating Add-ons for Internet Explorer: Toolbars on msdn.microsoft.com
And you should also take a loot at the Guidelines for add-on developers over at IE Blog.
What do you mean by no add on libraries? win32 is an external library, as is libX11, etc. Dev-C++ makes me think that you want pure win32. In that case, you want the common controls. I found this after a quick google: http://hyper.sunjapan.com.cn/~hz/win32/commctl2.htm . Hopefully it helps!
www.besttoolbars.net provides a platfrom for creating toolbar their solution is quite robust and has Javascript API so that you can write all the functionality using Javascript while the toolbar is created on C++.
