Bill's Design Tips - Flash, Graphics, and much more

[Expand] The emulator created in the previous example was a bit basic, so let's enhance it to support a proper networking command. One of the most widely used is IPCONFIG, which allows a user to determine the networking parameters of a host. The following shows an example:

[Expand][EXE]

For this I've tidied up the program. The main change is to create a message array which displays the messge for each command (textmsg[]). I've also created a Listener on the movie to catch keystrokes.

init();
inp1.text="";
textmsg = new Array();

textmsg[0]="Can't find command: " + str + " TRY HELP (or ?) ";
textmsg[1]="ipconfig /? Display this help message ipconfig /all Display full configuration information. ipconfig /release Release the IP address for the specified adapter. ipconfig /renew Renew the IP address for the specified adapter. ipconfig /flushdns Purges the DNS Resolver cache. ipconfig /registerdns Refreshes all DHCP leases and re-registers DNS names ipconfig /displaydns Display the contents of the DNS Resolver Cache. ipconfig /showclassid Displays all the dhcp class IDs allowed for adapter. ipconfig /setclassid Modifies the dhcp class id. /? Display this help message ipconfig /all Display full configuration information. ipconfig /release Release the IP address for the specified adapter. ipconfig /renew Renew the IP address for the specified adapter. ipconfig /flushdns Purges the DNS Resolver cache. ipconfig /registerdns Refreshes all DHCP leases and re-registers DNS names ipconfig /displaydns Display the contents of the DNS Resolver Cache. ipconfig /showclassid Displays all the dhcp class IDs allowed for adapter. ipconfig /setclassid Modifies the dhcp class id. /renew Renew the IP address for the specified adapter. /flushdns Purges the DNS Resolver cache. /registerdns Refreshes all DHCP leases and re-registers DNS names /displaydns Display the contents of the DNS Resolver Cache. /showclassid Displays all the dhcp class IDs allowed for adapter. /setclassid Modifies the dhcp class id.

Display this help message /all Display full configuration information. /release Release the IP address for the specified adapter. /renew Renew the IP address for the specified adapter. /flushdns Purges the DNS Resolver cache. /registerdns Refreshes all DHCP leases and re-registers DNSnames /displaydns Display the contents of the DNS Resolver Cache. /showclassid Displays all the dhcp class IDs allowed for adapter. /setclassid Modifies the dhcp class id.The default is to display only the IP address, subnet mask and default gateway for each adapter bound to TCP/IP.For Release and Renew, if no adapter name is specified, then the IP address leases for all adapters bound to TCP/IP will be released or renewed.For Setclassid, if no ClassId is specified, then the ClassId is removed.Examples: > ipconfig ... Show information. > ipconfig/all ... Show detailed information > ipconfig /renew ... renew all adapters > ipconfig /renew EL* ... renew any connection that has its name starting with EL > ipconfig /release *Con* ... release all matching connections, eg. "Local Area Connection 1" or "Local Area Connection 2"";
