How to render html (text-only) into an offscreen buffer?
in [MFC]
|
From: Dan on 28 Dec 2009 11:22 Hi, In my app I need to retrieve html text from db and render it into an offscreen buffer. What choices do we have in MFC? I vaguely remember that IE has an interface (view object, or something like it) that could be used to grab a rendered page into a bitmap. I'm not sure if that interface would work with non-url based data (i.e. without IE navigating to an url). Or, is there another option (except of writing an html parser/renderer)? Thx, Dan
From: Joseph M. Newcomer on 28 Dec 2009 13:04 There is an ActiveX control that is used in CHtmlView. If I were faced with this, I'd start there and see where things led. If you were able to intercept its OnPaint handler and substitute a DC of your own to a memory bitmap it would be ideal, but this may not be possible without using a hook function. joe On Mon, 28 Dec 2009 11:22:48 -0500, "Dan" <dan(a)dummy.com> wrote: >Hi, > >In my app I need to retrieve html text from db and render it into an >offscreen buffer.
