tcp - Delphi chat dont send message on some ip -


i want make simple delphi chat. use tcp/ip client , server socket. when try send message on computer getting error 10060.

to simplify if computer "comp1" , other computer in network "comp2" on both computer set same port (9096 example) on comp1 set ip of "comp2" , on "comp2" set ip address of "comp1".

ports open in firewall..

"comp1" personal , have dynamic ip address , router(maybe problem router?) "comp2" other computer don't have router , have static address.

when try send message "comp1" "comp2" message on "comp2" , don't have problem, if try send message "comp2" "comp1" not message , few seconds message 10060 error.

when try in local network local ip addresses program work.

is problem router or else?

thanks

this isn't delphi issue, network configuration issue. problem router receives message comp2 doesn't know it. need enable port forwarding on router forward port 9096 (or whatever tcp port using) on comp1. you'll need configure router reserve same address comp1 pc, otherwise program stop working if pc gets assigned different ip address when it's rebooted.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
