Hello,

Thanks Remy Lebeau I got my program working. My program captures the
TCppWebBrowser content into a BMP file using the DrawToDC function of
IHTMLElementRender interface which is working properly for 90% of internet
sites/pages.
But for some internet sites/pages the result BMP keeps black or partially
black (see attachment under usegroup borland.public.attachments) and some
objects e.g. the textbox do not appear. The
site I tested is http://www.web.de a popular online eMail provider in
Germany. To find out whats the problem I downloaded the HTML source of
www.web.de to my PC, added a <base href="www.web.de"> to make all relative
links working. I found out that it has to do with the <!DOCTYPE ... > tag.
When I remove this tag completeley the capturing works well!
Any ideas where the problem is located? Does the DrawToDC not support
rendering HTML pages with  DOCTYPEs?

Thanks for any help!

Please go to http://www.deja.com and do a search.  There have been many
discussions regarding problems with using IHTMLElementRender.

Hi,

thanks for reply but under www.deja.com there is no information about that
<!Doctype ...> problem or any hint that could bring me closer to the
problem!

Hello,

DrawToDC has problems with pages that use the <!DOCTYPE> tag, so DrawToDC
renders pages only in Quirks-Mode. For my purposes it is not enough and I
try to find a better way.

Thanks anyway to all!
