' DESCRIPTION:
'   A program to remotely view and partially control another PC via TCP/IP.
'
' INSTALLATION:
'	-Explode the zip file in the folder you want (es. c:\farview)
'   	-If not already existing, move the file MSSTDFMT.DLL in the system or system32 folder and register it
'    	(run regsvr32 msstdfmt.dll). This dll is neeeded by MSWINSCK.OCX.
'
' USE:
'   -Run the same FarView.exe program on both the PC connected by a network, one will be the
'    Client/Controlling and the other will be the Server/Controlled PC.
'    If properly configured, the two PC shouls connect automatically (CONNECTED will appear
'    in the connection status frame on both PCs)
'   -Use the controls available on the Client to configure the sw.
'   -View and control the Server desktop on the FarScreen form.
'
'   -The same file FarView.exe works as Client or Server depending on the command line parameters
'
' COMMAND LINE PARAMETERS:
'   FarView [/s /c] [/a] [/NClientName] [/nPC]
'            /s = Program working as Server (default)
'            /c = program working as Client
'            /a = autolisten for the Client, autoconnect for the Server
'            /Nclientname = the name of the client to connect to (see the 'Computer:' label on the Client)
'            /nPC = the number of the PC running the SW.
'                   /2PC = one session of the program will run on each PC (default)
'                   /1PC = the program will run simultaneously as Server and Client on the same PC
'                          (for testing purpose -> LEARN TESTING BECAUSE NO INSTRUCTION MANUAL AVAILABLE)

'
' TECHNICAL NOTES:
'   -TCP Ports used are 1001 for messages and 1002 for screen data.
'   -In the reality the Client program is a winsock server (listening/waiting for the connection), while the
'    Server is a winsock client (asking to connect to the Client, named ClientName)
'    This to simplify the connection between different PC Server (user) and the same PC Client (Admin).
'   -Best performance depends on Server, Connection speed and these items:
'       1. Number of colors used on the Server Screen (Control Panel > Screen > ... best is 256 colors)
'       2. Size of Server Screen or Selected Window (es. 800x600 best than 1024x768)
'       3. Bitmap Colors selected from Client (best is 256 colours)
'       4. Check of 'Fit Client Scr Res' chekbox (checked means faster but lower output resolution)
'
'       Performance with different configurations can be tested enabling Message Log ('Start Msg Log' button)
'       pressing 'Refresh Screenshot' button (or 'Reset Connection' on a single PC) and verifying the 'Refresh
'       Screenshot' time given in the Message Log textbox.
'
'   -Minimum Config data are saved in the file FarView.ini in the same folder of the exe program.
'       ClientName priority for Server session:
'           1PC: command line (/N), then Client PC name, then FarView.ini file
'           2PC: command line (/N), then FarView.ini file
'   -Log file is cFarView.log for Client and sFarView.log for Server. Always overwritten.
'
'   -For reasons I didn't catch, sometimes the screenshot transmission fails and it is lost.
'    Proper data flow can be re-established pressing the button 'Reset Connection'
