Help! Rendering Behaviour - IHtmlPainter

[Sophia Liu]

Hi,

Has anybody ever used IHtmlPainter to change the render behavior? I am
hoping to get the MSHTML to draw itself using DirectDraw, onto a
directdrawsurface.

I have downloaded the sample from
http://msdn.microsoft.com/Downloads/samples/Internet/ie55/RenderBehave/sampl
e.asp but could not get it compiled. Mshtml.h and mshtmlid.h are included
in the precompiled header as instructed. But I still got the following
errors...

d:\samplecodes\renderingbehaviors\downloads\samples\internet\browser\renderb
ehave\renderproject\behavior.h(20) : error C2504: 'IElementBehavior' : base

Thanks in advance for any help

To be more exact, I am looking into how I can get the html page render onto
a supplied DirectDraw surface or bitmp instead of onto a browser.

Am I looking into the right direction by investigating into MSHTML?

Hi,

i have the same problem: I want to render a html-page to a D3D-surface or at
least to a bitmap. The IHtmlPainter-interface sounds interresting. But wait
a minute - it seems only to work in the wrong direction: i am not interested
in drawing to a webpage using a bitmap or a D3D-surface! I want to draw the
whole webpage to a D3D-surface or a bitmap! Do you see a way to do that?
Currently i use MSHTML to render to a bitmap using IViewObject::Draw ( just
like printing ), but that is complicated and slow - but it works. I don't
know if it works with a D3D-surface instead of a bitmap - can you tell me?

About your compiling problem: Have you included the header and libs of
ie5.5? And have you changed the order of the include- and lib-directories?
It is described at
http://msdn.microsoft.com/downloads/samples/internet/libraries/ie55_lib/samp
le.asp.

If you find a solution to our common problem, please let me know!
