question before i attempt something

xenx · Post by **xenx** » Wed Jul 04, 2007 4:25 am

ok folks heres one for you, i know this must be possible but i have no clue how to do it, how do you run an EXE from code within another EXE

for example, im wanting to make a /bootmap command
so in game u can type /bootmap aresden /bootmap middleland
etc and the GServer you are on will attempt to boot up the other map from in game..

ooh ooh also.. can you end a task using code?

cause being able to kill a dead gameserver b4 trying to boot it wud be sweet..

u must be able to or else task manager wouldnt be able to.. but the big question is, does anyone know how?

/edit

ooh, CreateProcess and TerminateProcess, but they look complicated

ill play wif em tomorrow.

i did look their first:P but seeing the definition of a function and actually being able to use it are 2 entirely different things,

i havent had a go yet i got home late it will have to wait till tomorrow.

ShellExecuteA()

you mean like start up another HGserver, or just the map?

xenx · Post by **xenx** » Thu Jul 05, 2007 9:51 pm

to start up another Gserver
and hopefully end task on one thats running if it is,

so assuming you have one thats crashed, a GM can type /boot aresden and on the host pc it will end task on the aresden Gserver, and start it up again

why not just make an autoboot???

Yeah, I'm pretty sure that some HGServers stop Responding after a while on their own. Probably due to bad coding or something like that. So he wants a program or something that will close it and re-open it through a in-game command.

yeh, and the reason i want it in game is so GM's can do it without access to the host PC
the autoboot idea is sound but that doesnt detect when a HG hangs does it ?

Nope, It detects if the HGServer is closed, if it is, it re-opens it.

if you're in game then when you exit an hg.. it will have a pop up for the player data not saved. so you would have to go back to windows anyhow to close it. so there is really no point. i suggest that you remove the messagebox in the hg if you are going to do an in-game cmd.

zero posted the shellexecute line which is used to execute a program. there is, however, another function inside the shellexecute that is used which is createprocess. that function is strictly for the use of opening a program. shell can do other things though but createprocess is actually meant to open an exe/program. i advise that you look into studying these functions and become familiar with them so that you can come up with your own code to open and close an exe.

if you make a stable and clean coded hg. you woulnd't run into any of these problems.

the first part i think u misunderstood there, i want it so that if a HG hangs on my PC my GM's can reboot it, without access to my PC, lol it would be pointless if i wanted it to reboot HG's myself i agree

and yes i agree if the HG was perfect then this wouldnt happen, but no matter what HG iv worked on, who's, or how stable they claim it to be, theres always some player who manages to find some completely random way of crashing the thing, and its just getting on my nerves:P

so i figured a remote map reboot was a better idea than the GM's having to wait around for the hoster to come home so they can get a map back up, i cant be the only one that has this problem surely?

hell even HBint GMs had to wait hours on end to get maps back up when they crashed.

oh /edit, you also implied that i was waiting for someone to do the code for me as you said you suggest i come up with my own code to do it, i just wanna make it clear that i always try my hardest to come up with my own code and only use what other people post as a guide.
so dont worry im not askin for babysitting here i was just makin sure i was on the right track

iv never actually learnt C++ everything i have coded i have figured out from lookin at the HB sources and backwards engeneering it to figure out whats goin on, thats why a lot of the time im guessing

also thats why a lot of the time i will post here first just to make sure my brain isnt randomly makin stuff up

hmm... you should have stated your first post more clearly. include the whole part about making it remotely accessible.

bone-you · Post by **bone-you** » Sat Jul 07, 2007 12:27 pm

createprocess - file: taskkill.exe params: /F /IM HGMAPNAME.exe

example would be the aresden town : HGARESDEN.exe. That way you can differentiate between hgs and don't close the wrong one. This will kill the hg without save or a popup. Only used for hanging apps.

After that, use shellexecute or createprocess as has been said.

STARTUPINFO si;
PROCESS_INFORMATION pi;
char * szCmdline = "taskkill.exe /F /IM hgname.exe";

ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

CreateProcess( NULL, (LPTSTR*)szCmdline, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi );//kills the hg

ShellExecute(NULL, "open", "<fully_qualified_path_to_folder>+hg", NULL, NULL, SW_SHOWNORMAL);//reopens it

nice one bone that makes sence i can see how to do it now, it was the usage of those commands i was unsure of, you'v sorted me out now
