Hi!
This works nicely:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
HtmlViewer1.LoadFromFile('test.htm');But this doesn't:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
HTmlViewer1.URL:='http://myserver.com/test.htm';
Do I need to do something special to load from http? Is there an event
where I am supposed to download the page myself and feed THtmlViewer?

The example Browser.lpr supports http access via TIpHttpDataProvider
(unit Iphttpbroker).
https://wiki.freepascal.org/TIpHttpDataProvider
QuoteThe TIpHttpDataProvider handles requests for images and other
files by retrieving them from the internet.
It appears to be a simple plug-n-play solution,

THtmlViewer <> TurboPower TIpHtmlPanel!

Verify which component (package) you are using.

The HtmlViewer package contains a folder with lots of documentation
(HtmlHelp). It says about TFrameBrowser.URL:

"Read only and run time only. The URL property returns the most
recently selected (left mouse click) URL."
