Thank you very much for this first tip with LazActiveX!
I followed the examples, and for the first time, I can actually open the needed web-page using Lazarus.
I can also retrieve the needed HTML
there are just a few problems along this road.
When opening the main page for the needed web page, I receive script-errors which I have to click away manually.
The good part is that I can still log onto the remote site.
And then the display of the webpage is not that great
another 2 script errors which I have to click away manually
and then I can get hold of the HTML...
...
I suppose.
I MUST log on, this can not be avoided, so the first script errors must remain.
But from then on, I don't think I need the scripts running, I don't even need to display the page, only update the URL, and retrieve the returned HTML.
I have more testing to do, but this as an update!
Will look more for TWebbrowser and Delphi too.
Thanks!
