I am now the moderator of the KOL sections and I use it to publish lots of tips and tricks and some articles. Go and have a look! If you have a good KOL tip, do not hesitate, publish it on the forum!

It is based on the version available here.

Albert Drent, who created a full set of VCL components

and 

Gianpaolo Avallone, who provided the initial .obj files

I made several changes, though, mainly to do with memorymenagement stubs and possible linker errors. I also included a very basic KOL object with more Delphi like style naming conventions. By no means finished. Expect that soon.

Based on some code in the Delphi Magazine 85

at http://www.looprecorder.de/tut_l3codec.php is a good tutorial on how to obtain and install the proper codec, even without having to install the full mediaplayer 10.

kolrbcontrols1_51.zip

I include them because they are not easily available, but are very good.

This version has proper min/max support and optional anti aliasing using three optional types of oversampling.

Version 1.52:

ECM has written the mirror for MCK!...and fixed some bugs.

Note that as of version 2.10, kol.pas in PAS_VERSION mode is fully Freepascal 2 compatible. Vladimir Kladov incorporated the patches that were necessary into the official kol distribution. This download is only for convienience. Please note that kol still needs the support package ppdelphi.zip. This is also included but can also be downloaded separately here

Apart from a full kol 2.10 install for Freepascal 2.0.0 it contains:

1. a simple empty form

2. a WIN32 whois application

3. an example wordpad like application

4. an example of how HSL and RGB colors interact.

5. an object oriented example of how to draw polylines.

6. an xml demo with a simple but powerful reusable OO xml library

All examples except the first contain reusable objects for your own programs! The good news is, that they are exactly or almost exactly the same as found on this page for Delphi. The bad news: well, there seems to be a problem on some machines where the executables work, but exit with a memory leak. Sometimes it happens, sometimes it doesn't. I am still investigating this.

Please report if it doesn't work, but also report if the executables DO work. It will help me a lot in debugging. I run only AMD machines at home (an older athlon 1300 and a 64)

Please read this first, and modify fpc.cfg as explained.

If you mail to kol@chello.nl,  me and some other bravehearts that use KOL will try to answer you as soon as possible. Please note that you must allow for about two  days to get a reply.

You may put your question in English, French, Russian, Dutch or German. All answers will be in English. Apart from russian, which I am still learning (because of Kol) I can read fluently in these languages, so don't be modest, write what you want and how you want to express yourself.

You can also try to reach me at icq 218989577 to discuss KOL related issues. Only after 19:00 gmt +1.( I use a Miranda clone written in KOL, still alpha.)

Not everything implemented,

You must create controls you want to add with the form as parent. or use TCoolbar.Addband with a newXXX function.

Demonstrates how HSV and RGB values interact. Partly based on library code from:

 EFG's computerlab

Here's code that can scale a KOL application very comfortably.

I updated the demo to show you how to automatically handle a screen change using the WM_DISPLAYCHANGE message. The demo does not include BitsPerPixel change support, because I only have TFT's so I couldn't test that.

The 2005 version of my ever popular Rat Alert Document Alarm.

I won a programming award back in 1989-1990 with the first dos version and have revisited it many times and in many programming languages. This version is fully rewritten to reflect the current version of KOL (2.08) and is much cleaner than the old code. This idea may be 16 years old, the code is brand new!

I merged Colin Wilson's extended registry object with my KOL registry code.

Supports 9 types of chart, pies, lines, bars, etc.

Supports clipboard and printing

1.01 Resizebug fixed

Made it optionally stereo on request

This is based on Serhiy Perevoznyk's work and again an authorised translation (although a lot of it is new!)

http://users.chello.be/ws36637/

This function is in the windows API since NT4. It is more relevant now, because almost anyone has XP. It doesn't work on W95-Me

Handy for in memory database like applications

updated: small change on request to leave onchange handler free for the user. Added wndprocFontcombo.

It can still be used for the VCL too, I modified it faithfully and added two defines in WinDefines.inc:

$DEFINE KOL removes dependencies on sysutils.

$DEFINE USE_ERR enables err.pas for KOL structured exception handling

The latter option is only available if KOL is selected.

It includes extensive filtering capabilities. The driver itself can de downloaded from:

http://winpcap.polito.it/

This version is authorised by the original author Umar Sear and it is favorably reviewed by the winpcap team. A link, both to the KOL site as mine,  is included on their pages. I have had some remarks that there are other sniffers around for Delphi that do not need a devicedriver. Those are all based on the rather incomplete winsock2 API and are feature-wise totally inferior to winpcap based sniffing. Examples: you can't detect spoofing attacks with winsock2 based sniffers, you can't resend /redirect packages easily, you can't do remote capture. The neat thing about the winpcap driver is that it is a ring 0 kernel devicedriver and really completely independent from winsock2. If you really want a winsock2 based sniffer, may I cheekily refer to tdknetstat, that i wrote ages ago. It is still available from the official KOL site.

This Garbage collector supports both simple objects and objects that need finalization.

Smallest possible visual client about 18K.

Based on code by Charley Calvert, but translated to KOL, expanded and improved.

I wrote this for Hilde, a great entertainer and friend.

Now includes a manifest file for the ever more popular TeleTubby mode.

This is a tiny but very powerful guitar chord finder that supports different tunings and piano keyboard feedback. The chords are calculated, not looked up from a database. The chords can be copied to the clipboard for inclusion in documents or for further reference. Also has Midi support.

It includes full sourcecode and a helpfile.

The piano keyboard is a new and original KOL control. It can be used separately and supports playing the piano keyboard from the computer keyboard.

Define KOL to use with KOL. Otherwise, for the VCL the source is identical to the original 1.04 version by TobyBear. It includes a demo wave player exactly like the original by Tobybear too. ( But 38 K instead of 410K)

And this version released on the same day TobyBear released it! (But it was still a lot of work)

updated version to the final official release 1.0.1, added helpfiles

Comment from Rusell: Cool :)

The Rossler and Lorenz functions are iterated chaotic systems - they trace smooth curves that never repeat the same way twice. Lorenz is "unpitched", having no distinct peaks in its spectrum -- similar to pink noise. Rossler exhibits definite spectral peaks against a noisy broadband background.
I think  this works best by adding a very small amount of the modulated effect to the original soundsource like: sample:=sample + 0.05 *sample * OscillatorOutput. The effect is something like a synth with a cheap unstable transformer or leaky condensors. If you set the rate quite high (~0.2 = cheap 70's casette) it also simulates tape flutter.

Only ~80 K!, sources available on request and at the KOL site.

I couldn't have written this without the original console application sources by fobmagog available from sourceforge. This is a gpl'd program and not my usual free for all ware.

It does not rely on external dll's: it has its own codec. You can uninstall mediaplayer and it will still work.  This can lead to strange questions, it seems: no this is not a shell, it is a self-contained full featured win32 application.

If you downloaded KolOleRe.zip from the KOL website recently, you already have it. It is now part of the "official release".

The zipfile also contains a KOL Registry object that mimics the VCL Tregistry component.

The screenshot is from Dutch Army Knife: a small tool that is still a secret!

example:

thaddy AND (mess OR website)

becomes:

select * from TABLENAME where ((FIELDNAME like '%thaddy%') and ((FIELDNAME like '%mess%') or (FIELDNAME like '%website%')))
