ControlZ 1.2
------------

Copyright © 1994, C. van Zwynsvoorde. All rights reserved.


ControlZ is a custom control library (DLL).
It basically aims at making developers job easier. 
It is Borland's Resource WorkShop 1.01+ compliant. 
That means you can customize the controls and use them directly 
with Borland's Resource WorkShop. To do this you need to select 
Options|Install Control Library when editing a dialog box. If you 
are not a Borland user, you can still use the ControlZ.DLL at 
run-time but will probably experience problems if trying to use 
it interactively in your resource editor. In that case you might 
want to let me know (see at the end of this file).

Currently, 7 types of controls have been implemented:
- an analogue scaler,
- an analogue dial,
- an anologue tuner,
- a new type of hierarchic combo-box,
- a new type of hierarchic list-box with horizontal (caption)
  scrolling,
- an extended static text control,
- an extended arrowed link static control.

I have included a demo program in this package. It gives an 
overview of the different types of controls and the associated 
options. The sources for the demo program have been included. It 
consists of an extremely simple C-source file, along with an 
RC-resource file. Yet it is relatively powerfull and gives a good
demo. This is because the power is contained in the ControlZ.DLL. 
Indeed ControlZ has been designed with the intention of putting 
more power in the DLL itself, so you can make very quick "working"
models of your future applications just by defining the resources.
Therefore you save time at this stage were you are often in a 
rush to get something to show in order to get funds for your 
future application.

The demo brings up a succession of dialog boxes containing a number
of the ControlZ custom controls. In every dialog box you will find
a Help button which you might want to click to get a more extensive
description of the demonstrated control.

If you have the Borland's Resource Editor, you are encouraged to 
install the ControlZ.DLL custom control library and have a look at
how easy it is to use and configure the controls in your dialog 
boxes.

Remember ControlZ.DLL is not a VBX ! Thus it has no complicated 
tricks to get it working with C and the resource editor and/or 
compiler. Also this means you may expect it to run on future 
versions of Windows (which is not sure for VBX controls).

The ControlZ.DLL itself is fully operational. It comes with an 
associated header file called ControlZ.H and the on-line 
documentation contained in the ControlZ.HLP and ControlZ.WRI files.
The WRI file has the same contents as the HLP file but can be more
easyly printed.

Because the ControlZ.DLL is fully working, you are not only able 
to run the demo, but also to use it right now with your resource
editor, though an "unregistered copy" reminder will come up now
and then. This allows you to use it right now in your own
applications and register after a while if you find it useful.

Registration
------------
Well indeed I hope you find it useful. So here is how to register.
The registration is 50 NLG (Dutch Guilders, < $30). See the 
REGISTER.TXT file for more details. You will get a registration 
name and a password as soon as I have notification of payment from
the bank. Note that there may be some delay between the time you 
pay and the time I receive notification of that.
This is a per-copy price. Thus if you will have copies of ControlZ
on N stations in your orgranisation, then please register N copies.

Commercial use of ControlZ
--------------------------
If you intend to make commercial use of ControlZ, you may want 
either to:
- register as many copies as needed, or
- get the source code, in which case you should contact me first.

Needed configuration
--------------------
To run the demo program you need to have the BWCC.DLL file 
installed on your system. This file is also needed by the 
ControlZ.DLL when editing the resource (but Borland's Resource 
Workshop should already have loaded it). Yet ControlZ.DLL does 
not require the BWCC.DLL file at run-time.

ControlZ.DLL is intended to run under Windows 3.1. I actually made
no test with previous versions of Windows, nor with WindowsNT or 
Windows for Workgroups.

I developped the DLL at home on a 386/25Mhz. On such a 
configuration some controls act quite slow (especially big dials).
To get the buttons generate the expected 20 steps a second, a
486/33 should be enough. Of course a Math Coprocessor should help.

There are no "particular" memory requirements for ControlZ.
