You should not unescape recursively.
Input to EscapeHTML: '<' Output: '<' : Correct
UnescapeHTML: input '<' Output '<' Wrong.
This is because you replace '&' with '&' resulting in '<' which is
translated to '< ' in the next line.

This is a very minimalistic implementation covering only partial ascii
character escaping. To cover ASCII only in unescapeHTML you should also add
' ' which corresponds with the space character ' '. Also the format
&#entity_number; is missing ('<' or '<' equals '<')
To support iso-8859-1 which is

That would be a solution for this problem. My previous comments on the
"minimalistic" approach of the implementation suggest a different approach:
scan the source string once and replace html entities as you find them (with
a look up table for exam

Interfaceconnect calls Advice on the objects IConnectionPoint. I can't share
Delphi code here but essentially what you do is:
Get IConnectionPointContainer (CPC) from IUnknown (ActiveXObject) :
ActiveXObject.QueryInterface(IConnectionPointContainer, CPC);
Get IConnectionPoint (ppcp) for the IID
Regarding the tlb to pascal "conversion", AFAIK there is no support in fpc.
Delphi is clearly better equiped to work with COM objects.
I have also been playing around with a generic eventsink class but the
problem is that events can have parameters (and a lot do). Your suggestion
of using TNotifyE

Using variants you can transparently "walk" along the exposed objects. The
variant contains the Idispatch of the object and gets the exposed methods at
runtime. Properties are implemented as get and put methods or just get
methods for read only properties.
If you have something like
Itransducers
Always thanks!
Given your evident experience on this matter, I kindly ask your advice
on what is best to do.
opt 1) create a fpc class with some pascal style methods, which in
their implementation use variants and call the IDevice class with
late-binding . meaning that there is no compiler ch
