Computing: Free Pascal Programming

Network computers.


Download NetworkShow desktop application (Windows 64bit) Download NetworkShow source code (Lazarus/Free Pascal)

Description: NetworkShow is not really an IP scanner. It does not scan subnets, but uses the Windows command line tool ping.exe to determine if given computers (defined by a network description file) are actually present on the network or not. The network description file contains the IP addresses of the hosts to search for. The application uses Ping to determine if the host is alive or dead, arp to get its MAC address and nslookup to resolve their DNS names. See the help text of the application for further details.

Free Pascal features: Usage of the process unit to run command line programs from within a Lazarus GUI application and to catch these programs' output. Usage of timers. Usage of the Open dialog to select a file.
