What do you think of Delphi 6? I personnally hear nothing but good about
it. And ofcourse, Borland is doing a great job with releasing stable and
very good products. However, after I have installed and used Delphi 6
for a couple of days, I can only see one big reason to make the switch:
the cross-OS compatibility. Meaning: Delphi 6 is Kylix compatible.
If you aren't sure whether you should upgrade, my advice is: don't
(unless you're part of a big company, ofcourse). For home users I don't
feel there are many great new features. You can read more about the new
features here: http://www.borland.com/delphi/del6/whatsnew.html
Our web site has undergone an aesthetic overhaul and now has a new look.
The design is the work of Renato Gaiarsa <renato@knowhow-online.com.br>.
Please take a look and don't forget to report if you see any problems:

2. APPLICATIONS WITHOUT VCL (II)
By José Manuel Rodríguez (JMR)
Copyright: JMR, Madrid 1998/1999
In the previous chapter we approached the reduction of the size of the
executables by using a unit that, apart from extending the range of
dialog boxes provided by the VCL, we could use totally independently
from the VCL, allowing us to create much smaller executables. However,
the range of applications that could be created using only APIDlgs
without use of the VCL was very limited... some very stereotyped
applications with very concrete dialog boxes and mainly DLLs or
applications that run hidden during the greater time of their life and
that from time to time show information or get some data from the user.
In this issue we are going to go much further and we are going to extend
the number of applications that can be done without resorting to the
comfort of the VCL.
The idea is to develop an object which totally encapsulates an
application. The application encapsulated this way will be a mini-
application, of course, but totally functional, with its menu, tips,
possibility of reacting to Windows messages or messages defined by
ourselves, etc. If every time we have to show a message or request
information we also make use of APIDlgs then with the conjunction of
APIApp and APIDlgs we can cover a great number of programs without
having to make use of the VCL, obtaining executables 10% smaller than
their VCL equivalents, although this is naturally difficult to estimate.
Description
===========
The APIApp unit mainly contains the TTinyApp object (don't mistake with
component) which provides total functionality for the instantaneous
generation, although non-visual, of complete applications. These
applications are shown as an icon in the tray of the task bar, have
their own popup menu with associated actions that we define and
additionally can process Windows messages or user defined messages. At
any time we will be able to add new options to the menu or redefine it
totally, to change the icon shown in the tray, etc. We are going to see
two possible uses:
a) Let's figure we have a conventional application that we want to
monitor. This application can be a normal executable, a standard DLL,
an ISAPI DLL, or whatever... and there can even be multiple instances
executing at the same time and we are interested in knowing when this
application receives a command from the user. (For example: an HTTP
client has asked for certain rows of a table from the Web server where
our ISAPI is executed, the application has already opened a file 100
times, etc.) Then, we only have to define our own messages so when these
events take place we send them accompanied with the 'Handle' of our
main window in WParam. Next we create our application descending from
TTinyApp and we tell it to react to these messages (showing a message
in a window and creating a file log if necessary, etc.). Once we have
launched our 'TinyApp' we will be informed at any moment from whom and
when a message is received...
b) Since we have our own menu at our hands, actually, any application
that doesn't require a great unfolding of graphical interface can comply
to this type of application: programs to modify the configuration of
Windows or other programs, mathematical calculations, diagnostic
programs, etc. Obviously, a great part of larger applications is outside
the reach of APIApp, but there are many situations in which its use can
be considered, especially in complementary applications.
Functioning
===========
APIApp is totally based on the object TTinyApp, so it has all the
advantages of OOP but without the burden of the use of memory and
resources that components imply. Of course, the advantages of visual
design are lost, but its use keeps being quite easy. In fact, there's
no need to know anything about OOP to obtain all its performance.
PUBLIC METHODS
The public methods are:
constructor Create(cAppName, cIconName: String; MainProc: TMainProc);
virtual;
procedure AddUserMsg(MsgID: Integer; MsgAction: TMsgProc);
procedure AddMenuOption(OptionStr: String; OptionID: Integer;
OptionAction: TOptionProc);
procedure SetNewIcon(const cIconName: String);
procedure ResetMenu;
procedure Execute;
procedure Free;
Create
------
constructor Create(cAppName, cIconName: String;
MainProc: TMainProc); virtual;
It just creates a TTinyApp object.
The parameters are:
- cAppName: Internal name of the application and what is shown in the
tooltip when the mouse passes over the icon. If you supply an empty
string, no tooltip will be shown.
- cIconName: Name of the icon resource we want to show in the tray. The
name should be in capital letters and should match the name of an icon
included as a resource in our application (with the {$R} directive).
If you pass an empty string or the name of an icon that does not exist
in the resources of the executable then the default icon will be used.
- MainProc: It's the name of a TMainProc procedure.
TMainProc = procedure(var Msg: TMessage);
The value for the MainProc parameter can be nil or a procedure that
will be called automatically by TTinyApp when you click the icon in
the system tray. It should never be called directly and will receive a
Windows message as parameter.
AddMenuOption
-------------
procedure AddMenuOption(OptionStr: String; OptionID: Integer;
OptionAction: TOptionProc);
When a TTinyApp object is created a popup menu is assigned to it that
only contains the option "Exit" which finishes the application. This
method allows us to add options to the popup menu of the application.
The parameters are:
- OptionStr: The caption of the new menu item.
- OptionID: A numeric identifier for the menu item. It must be unique,
but it can be any number starting from ID_USERFREE.
- OptionAction: It's a procedure of type TMainProc (described above).
This procedure will get executed when the user clicks the menu item.
AddUserMsg
----------
procedure AddUserMsg(MsgID: Integer; MsgAction: TMsgProc);
When a TTinyApp object is created, it creates a hidden window to which a
window procedure is assigned for handling the specific messages that the
hidden window receives, and the rest go to Windows. Obviously, being a
hidden window there are messages such as WM_PAINT or WM_NCHITTEST that
it will never receive but it will get other Windows messages like
WM_ACTIVATE or WM_CLOSE and, of course, messages defined by us. Calling
this function we can specify procedures that will act as message
handlers for the messages we are interested in.
The parameters are:
- MsgID: Message identifier. It can be a Windows message (like WM_CLOSE)
or a user-defined message (starting from WM_USERFREE).
- MsgAction: The name of a procedure of type TMsgProc. This type is
totally analogous to the VCL type TMessageEvent (used by
Application.OnMessage for instance) but here it's just a procedure,
not a "procedure of object" like in the VCL. The parameters it takes
are exactly the same: Msg is a structure of type TMessage and Handled
is a variable passed by reference that we can set to True to prevent
the message from being processed by Windows.
SetNewIcon
----------
procedure SetNewIcon(const cIconName: String);
Allows us to change the icon that is shown in the system tray of the
task bar, even during the execution of the application. It will be shown
activated or deactivated according to the state of the application.
Parameter:
- cIconName: Name of the icon resource we want to show in the tray.
The name should be in capital letters and should match the name of
an icon included as a resource in our application (with the {$R}
directive). If you pass an empty string or the name of an icon that
does not exist in the resources of the executable then the default
icon will be used.
ResetMenu
---------
procedure ResetMenu;
Allows us to eliminate all the options of the popup menu and their
associated actions, except for the option 'Exit' which is necessary to
be able to finish the application.
Execute
-------
procedure Execute;
Starts the application. When this method is invoked, the icon gets shown
in the tray of taskbar and the application enters its message loop,
looping until it receives a WM_QUIT message, as usual. Once the message
loop is finished the application finishes but the object is not
destroyed (this makes it possible to call Execute several times).
Free
----
procedure Free;
Destroys the object and releases all allocated memory. It is necessary
to call this method when we finished using TTinyApp.
PUBLIC PORPERTIES
The public properties are:
property Enabled: Boolean read FEnabled write SetEnabled;
property Wnd: THandle read FMainWnd;
- Enabled: Read/Write. Allows us to know the status of the TTinyApp and
to activate or deactivate it at will. When TTinyApp is deactivated, it
doesn't receive messages from the user so it won't popup a menu or
execute the default action although the invisible window still
receives messages. It is useful to deactivate it while a menu option
is being executed to prevent it from being called again.
- Wnd: Read only. The Handle of the main (hidden) window of a TTinyApp
application.
Quick start
===========
The use of APIApp is quite easy, comfortable and intuitive. Normally
it's enough to create a TTinyApp object, add some menu options and call
its Execute method, calling Free when we are done:
var
MyApp: TTinyApp;
begin
MyApp := TTinyApp.Create('My program', '', nil);
try
MyApp.AddMenuOption('&About...', ID_USERFREE + 1, ShowAbout);
MyApp.AddMenuOption('Con&figure', ID_USERFREE + 2, AppConfig);
......
MyApp.Execute;
finally
MyApp.Free;
end;
end.
See the example TestTiny for a complete demo application (useless from a
practical point of view).
Comments
========
a) This unit will only work in Win32 environments. It has been tested
only on Delphi 3 but I don't see any reason for it not working in
Delphi 2 or Delphi 4+.
b) Like the first part, all the code included is the original work of
the author, Jose Manuel Rodriguez, but I must again give thanks for
suggestions and comments to Jose Luis Freire, Miguel Oliver Angel
<maoliver@balearcom.es> and Nicolás Aragón <doperider@arrakis.es>,
mainly the latter since I implemented his idea. Apart from authors I
mentioned in the previous part, I must also thank the many authors of
TrayIcon-type utilities that can be found on the Internet.
d) This unit can be used free of charge in compiled programs without any
kind of restriction, but --if you use it-- I would be grateful if you
mention the author in the credits of the program.
If it is distributed as source code, the whole package should be
distributed, free of charge, with all files in full, including the
copyright notices.
Any suggestions, corrections or criticism (constructive, of course)
would be welcome.

3. SHUTTING DOWN THE PC AT A GIVEN DATE/TIME UNDER WINDOWS NT/2000
By Roberto Martínez O. <rmartinez@ieqsa.com.mx>
The program Timer you can find attached allows you to set a date/time
for a PC running Windows 2000 or NT to turn off. This program is useful
when we want to leave some process running on the PC and we don't want
to wait until it finishes to turn off the PC: we just program the
date/time and leave. The program will turn off the PC.
The program is of the type "SystemTray", copied from the example by
Ernesto De Spirito you can find in the Delphi Tricks section of the
Latium Software web site, to which I added a Timer component and the
routine to force the machine to turn off.
NOTE: This program will only work properly if you have a motherboard
that allows the OS to turn the power off. Otherwise, Windows will
shut down, remaining at the 'You may now turn off...' screen.
