Messing around with random codesnippets written for Indy 9 using in XE7 and 12.2 (Resolved)

[JohnLM 14]

As the subject implies, I am just messing around with code snippets found on the web.  Some I downloaded from people writing code for various purposes.  Anyway...

 

So I have this code snippet that I downloaded and was trying to see what happens. 

 

The snippet has the line:  IdTCPClient1.writeln('start');

and in another: listbox1.item.add(IdTCPClient1.readln);

 

These two commands do not appear in Indy 10.x for XE7 and D12.2 versions. 

 

Have those commands been moved some place else in the IdTCPClient component and where?

resolved - I figured it out.

Why are you looking at Indy 9 snippets and not at Indy 10 snippets?

Yes. All of the I/O methods that were present in the TIdTCPConnection class in Indy 9 were moved to the TIdIOHandler class in Indy 10, eg:

 

IdTCPClient1.IOHandler.WriteLn('start');

 

ListBox1.Items.Add(IdTCPClient1.IOHandler.ReadLn);

 

Also, many of the older writing methods in Indy 9 were renamed to Write() overloads in Indy 10.

Because I don't know what version the code snips are until later on in reading the entire discussion.  These are google search results. I see a snippet and read what's going on.  I try it and see if it works on my main laptop computer which has XE7.  And if it doesn't work either I'll keep reading further or try it on Delphi 11.2 or 12.2 as those are the three versions I have.  But not all google-found search results include the versions of Indy in those discussions.

I am just searching google for info and if code snippets are given I try them out for fun or interest.  Not all say the version of Indy, and if I can't find any further info to resolve any issues that I might run into while trying those snippets then I might post a question here on Praxis, or not, and move on.  Delphi is my hobby.

 

Sometimes I get *new* ideas from these random google searches and they become hobby projects.  In fact, I just started a new project from this as of yesterday, a Client/Server app and it appears to be working okay.  First time I ever accomplished this as I always wanted to get a client/server (send/receive text) project working via Indy but failed many times.  But not this time.  But is it perfect or correct?  Probably not.  But it works. :)  I was meaning to post a few questions because I had many issues, about 18 or more hours worth (I just could not stop).  I'm stuck on an issue or two and still working them out.  Maybe I'll post a question or two later, if I can't figure it out as it is driving me nuts. 

 

Also, I have searched around on all my versions of Delphi (xe7, 11.2 and 12.2) and did not see any documentation or Samples folder for Indy. 

And the link in the About of the Indy components (when you rightl-click the component in the IDE) do not work on any of those Delphi versions.

The link itself works just fine.  Perhaps you are referring to the fact that the website has pages missing?

Thanks.  I think this one works better and a faster response time (searches/lookup etc): 

 

One of those files, a .zip of the HTML Help, has been uploaded to this repository.
