Question Converting Delphi source code to Typhon

Hello all, I am quite new to both Delphi (v4--I believe) and Typhon (v7.4).  I have the source for an old Delphi program,
trying to compile using Typhon has some issues.  Cannot resolve Delphi items such as Variants, TWebBrowser, IStream, IPersistStreamInit ....etc.... I have tried  installing Typhon packages, no luck.
1) Are there packages from other sources available?
2) Is there any documentation, apart from the list of components, which provide some idea as to how to use the components.
Thanks for your responses.
 

Thanks for the conversion tool tip.  I tried it, but there were too many exceptions.  The amount of code to convert is less than 200 lines so a manual conversion is ok, and preferable. The painful part is the small number of components missing for which I cannot find substitutes.  Will just have to continue experimenting I guess.

Take a look at this site: wiki.freepascal.org/Webbrowser
I think that there is an alternative component for you.

IStream is available in the unit "types"
Variant type is available in the unit "variants"
C:\codetyphon\fpcsrc\packages\winunits-base\src\activex.pp for IStream.....

Cheers

I gave it a quick try and am closer to a solution..not quite there yet, but looks good! You sure know your way around the typhon libs.
 

I'm often use the function "Search in files" for a component name. If there is no result then I'm changing to the WWW to get a result.

Many thanks, LuZZZZi and Sternas Stefanos, great tip.  I can complete it from here.
