"The IPersistStreamInit interface, and its associated methods, can be used
to load a HTML content from a stream using the WebBrowser control...", from
MSDN, Topic "Loading HTML content from a Stream".

I'm not sure how this translates to perl, I don't have any experience using
COM from perl.

Also, in regards to (1) and (2), these should be possible if you subclass
the webbrowser control. IIRC, some of these questions were answered in past
issues of MSDN Mag. which is available at http://msdn.microsoft.com/msdnmag.
I believe they appeared in the "C++ Q & A" column, but not sure.

HTH,
Randy.

I'm not absoulutely convinced that hiding HTML source is impossible.
However I am convinced that if you could hide it the client/browser
couldn't see it. After all, the browser has to read the source HTML
in order to render it. I'm not sure what value write-only HTML source
would be. Probably about as useful as write-only memory which is just
a little more useful than erase-only memory.

Thanks, that does work, but I will need to load large pages.
What I've been asked to create is almost like an ebook. I need to embed the html in the app (the client will be using perl2exe) and then disable right click so that a user can't right click to view source or cut-and-paste.
If I have to use a file, I suppose I could use two-way encryption, but I still need to figure out if it's possible with OLE to disable right click.
I know the users will be using Windows and that's I'm trying to use Win32::OLE.
 
Thanks again,Do You Yahoo!?

Try navigating to 'about':

 # untested
 $ie->Navigate("about:hello%20world");

Be careful because you can only send so much HTML that way. Longer pages
will have to be sent loaded via file://
