Title: How to Build a Multi Screen Emulator
function EnumWindowsProc(hWnd: HWND; lParam: LPARAM): Bool;
// The EnumWindows function is of type:
BOOL EnumWindows(
WNDENUMPROC lpEnumFunc, // pointer to callback function
LPARAM lParam // application-defined value
);
{
I will call EnumWindows(@EnumWindowsProc, 0);
The ¡°EnumWindows¡± function loop over all windows (visible or invisible):
for each window there is a call to the callback function
¡°EnumWindowsProc¡± wich must be implemented.
The first param ¡°hWnd¡± is the handle of the current window.
A possible implementation of the ¡°EnumWindowsProc¡± function may be the inserting
of every handle in a list.
According to our target we must insert in a list the handle of
the following windows:
1)Visible windows //(IsWindowVisible(hwnd) = True)
2)Not my application window
//var processed: DWORD;
//GetWindowThreadProcessID( hwnd, @processID );
//processID GetCurrentProcessID
3)Not the taskbar window //hWnd FindWindow('Shell_TrayWnd', Nil)
4)Not the desktop window //hWnd FindWindow('Progman', Nil)
}
// This is the code:
unit ProcessView;

In the main program I used a variable named Monitors of type
¡°array of TstringList¡± whose dimension is given by the number of buttons
(different monitors available) to keep in memory all the hanldes
associated with every button. Another variable named CurrentMonitor
keeps in memory the index of the actual monitor (the caption of the button).
This is the code:

In order to prevent multiple instances of the application I inserted
some lines of code inside the project source;
this is the modified source:
}
program Project1;
uses
Forms,
Windows,
Unit1 in 'Unit1.pas' {Form1};
{$R *.RES}
var
atom: integer;
begin
if GlobalFindAtom('Monitors_Procedure_Atom') = 0 then
atom := GlobalAddAtom('Monitors_Procedure_Atom')
else
Exit;
Application.Initialize;
Application.CreateForm(TForm1, Form1);
Application.Run;
GlobalDeleteAtom(atom);
end.
{
The GlobalAddAtom function adds a character string to the global atom table
and returns a unique value (an atom) identifying the string.
The GlobalFindAtom function searches the global atom table for the
specified character string and retrieves the global atom associated with that string.
If I have already run the programm then the GlobalFindAtom function returns a value
0 because the atom is already present: in this case I abort the execution of the program.
Instead, if the GlobalFindAtom function returns 0 then this is the first time I run the
program, so I create the atom. At the end I delete the atom.
In order to remove the button on the taskbar I inserted the following code
inside the OnCreate event of the form:
}
{...}
ShowWindow( Application.handle, SW_HIDE );
SetWindowLong( Application.handle,
GWL_EXSTYLE,
GetWindowLong( application.handle, GWL_EXSTYLE ) and
not WS_EX_APPWINDOW or WS_EX_TOOLWINDOW);
ShowWindow( Application.handle, SW_SHOW );
{...}

In order to have a tray icon in the traybar (wich display a menu containing showing,
hiding and closing of the form), I used a component (TTrayIcon),
