Have you considered
URLDownloadToFile()?

man i am new to visual c++ .i be happy if u guys give me an example of how to use it. Just URLDownloadToFile() will not help me. You migh say msdn but that is not readable at all for starter.!! Furthermore, i do not want to download a url in file i just want to load its html code into a editbox for further process. -- modified at 13:19 Tuesday 11th July, 2006

Sure it is. I started using it some 15 years ago.

This makes no sense. If you are wanting to edit the HTML, use
URLDownloadToFile(). You can then plug the contents of the file into the edit control. Using the alternativeIHTMLInterfacewould only complicate matters.

HTML from where ? if it's from the web, David gave you a good starting point. else, if it's simple html text, just do a
SetWindowTextof the HTML code to the CEditBox; but it will not be formatted.

my whole intention is to extract data from a html page so it would be easier to load the html instead of the file !! i have done this in visual basic 6 but i need to do it for a project that is visual c++ 6 and so far i just get unrleated answer and no example!!! i think this the nature of visual c++ programers unlicke visual basic programmers!!

I've given you more than enough information to solve your problem. As a matter of fact, you've been given several solutions to the same problem. That's very gratuitous in my book. This retrieves all of the

Then do as I've already suggested. Use
URLDownloadToFile()to download the HTML to some temporary file. You can then plug the contents of the file into the edit control. It's a very simple procedure.

See here. Once you have a file, you can then open the file using any number of methods (e.g.,
CFile,FILE*,CreateFile()).
