Good people:

I have the Memo1 with a few lines, how to clear it to zero lines?

I tried lines.count := 0; but that did not work.

Then after I clear it, how to put just one line into it, for example: 'This is line1'.

And also, where can I find documentation on how to use these methods? that start with a .dotMethod for TMemos, and just as well for other type of objects?

Thanks!

meulinux:
Memo1.Lines.Clear;

Great help, meulinux.
That's a powerful statement.

Now, if you don't mind, where can I learn things like that (part of my original question).

Thanks!

In google, I just typed "lazarus TMemo" without quotes and the first link was the reference documentation:

http://lazarus-ccr.sourceforge.net/docs/lcl/stdctrls/tmemo.html

And then you can click on links there are find the reference for TMemo.Lines:
http://lazarus-ccr.sourceforge.net/docs/lcl/stdctrls/tcustommemo.lines.html
Then click on TStrings:
http://lazarus-ccr.sourceforge.net/docs/rtl/classes/tstrings.html

Where you can read:

procedure Clear; virtual; abstract; Removes all strings and associated objects from the list.

There are also links to docs here: http://wiki.lazarus.freepascal.org/LCL_Components
One other thing, please try to keep questions about the LCL in the LCL sub-forum =) thanks

See this post - and the next for sources of information on FreePascal, Delphi (handy, as Lazarus is almost always compatible), and Lazarus:
http://lazarus.freepascal.org/index.php/topic,13951.msg73534.html#msg73534

Don't know if I mentioned it there, but Delphi online documentation can help, too:
http://docwiki.embarcadero.com/RADStudio/en/Main_Page, especially the pages under Delphi Reference

Hope this helps,
