Can a TCppWebBrowser handle SSL, or do I need to use a TIdHTTP component 
with a TIdSSLIOHandlerSocket for that?

I know the later will work and will get the page's source, but then I need 
to write the code myself to parse through all the html and javascript to 
find how and where to submit the form on the page.  If necessary, I could 
probably do that for straight html, but it gets too complicated if the site 
throws javascript into the mix.  And in either case, it feels too much like 
I'm re-inventing the wheel here.

I haven't used TCppWebBrowser before, but it looks as though it may provide 
that parsing for me once I figure out how to use it.  If it can't be used on 
a secure site, though, then it won't help me.

Any suggestions on what's the best approach here?  My application needs to 
get a web page (which will have a form on it), find all the input fields on 
that form, check their values, assign new values to some of them, perform 
whatever the form's submit button has for its onclick event, and post it 
back to wherever the form's action property says it needs to go.  Can a 
TCppWebBrowser be used for that?  If so, can it be used on a secure site? 
If I need to use the TIdHTTP component, is there a component or library that 
will help with parsing the html response it returns into the input fields 
I'm interested in?

Of course.  TCppWebBrowser is just a wrapper for IE's ActiveX object, so it
can do everything the main IE browser can do.

> Can a TCppWebBrowser be used for that?

Yes.  However, TCppWebBrowser is a visual component, and what you describe
are not visual operations (unless you are going to display the form to the
user to fill in), so TCppWebBrowser might be overkill for your needs.

Yes.
