Hi all, got a design issue and not sure how to address it - was hoping 
someone can point me in the right direction.

We have a custom installer written in BCB that uses a TCppWebBrowser to all 
the user to register there product.  The Browser simply connections to a web 
page on our server via https.  I use the CppWebBrowser because i didn't want 
to get tied down with coding the https communications.  The system works 
fine but now i need to propagate two fields on the html page, before it is 
displayed to the user.  Currently i'm loading the page by calling the 
navigate() function.  Can anyone point me in the right direction for 
resolving this.  I assume i need to save the html to some sort of stream and 
then parse it before loading it.  However I've no idea on how to do any of 
this:


Many thanks in advance,

Mike Collins

Since you control the http server why not have it propogate the fields for 
you?

If not, then do a search in the archives for filling form fields and you'll 
find
tons and tons of examples.

In the TCppWebBrowser's OnDocumentComplete event, you can use the
browser's DOM interfaces to access the individual elements of the
page.  Starting with the Document property, query it for the
IHTMLDocument2 interface, and then go from there.  Refer to MSDN for
more details:

No, you do not.  The content can be updated dyanmically inside the
browser.
