<div>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>And I
suspect it opens up an area of great usefuleness beyond Twebbrowser.<br>
<br>
I have been looking (as many seem to!) into streaming the content of <br>
Twebbrowser or TembeddedWB into a data base Blob field, seems to be the <br>
grail of this kind of programming!<br>
<br>
And generally I want to be able to live re-edit the returned material<br>
in a Twebbrowser window.<br>
<br>
Wanting to retain images etc, I have looked at MHT and it seems that it <br>
is possible to use a NameSpace set up to stream them back to the<br>
<br>
browser window once in the DB, but I can find no other way than<br>
initally saving to disk to get an MHT out of a browser back to the DB <br>
blob field. I want to avoid using the disk because of the overheads. <br>
<br>
So I want to know how I might get a binary representation of the<br>
actual rendering of the HTML in Twebbrowser into a stream and into a<br>
blob and back when wanted. NOT as MHT or HTML! As already rendered<br>
content this stream would be very fast to re-process back into a <br>
Twebbrowser.<br>
<br>
It just seems that there must be something like a TCanvas in the <br>
Twebbrowser. But a pure TCanvas may not render the 'data' back into the<br>
browser as edit able material.<br>
<br>
** Is there something in how Twebbrowser renders the HTML, a 'binary <br>
layer' that can be streamed back and forward? <br>
<br>
** Something that has all the rendered elements and <object> <img>
<etc<br>
..> as binary available for streaming?<br>
Is component streaming an sensible avenue? <br>
<br>
<br>
<br>
i.e. TStream.WriteComponent <br>
