Hi guys, i'm just wondering if it would be possible to end a currently running program from within a different program,
eg.
Main.exe is run
Main.exe tells Second.exe to load(via execute file)
When Main.exe is closed, Second.exe is still running
The user then has to close Second.exe, which is an inconvenience.

Is there a command in dbp, or a .dll i can use which will close that program(Second.exe)? Both programs are made in dbp.

Thanks for any help you can give

You could probably do it by playing around with TerminateProcess (Win32 API) but that might be a bit fiddly. If timing is not absolutely critical, just create a specific file which second.exe looks for then closes if it finds it.

eg:

do
...code...
if (file exist("die"))
delete file "die"
end
endif
loop

there are a few ways in general to do this but I am not sure if any are implemented in dbp.

hmmm, i actually thought about the creating a file technique right after posting, that would be ok i guess. How fiddly would terminate process be exactly? if its just a case of loading and calling a .dll then i think i could manage that...

you could use the clipboard for this, like second.exe continuesly checks the clipboard if it contains something like "main.exe is closed" and make your main.exe so that it writes "main.exe is closed" to the clipboard once you end the program.

If you can get the window handle, you could send a quit message to it.

i have a function that does this via the win process id or the name of the process. It attempts the CloseMainWindow method, then checks if it shut down, if not it Kills the process, but unfortunately this is vb.net so there goes that idea.

is the window handle the same as the window caption? eg. the name at the top of the window? if so thats pretty easy to get, if not i'll probably use mussi's clipboard method, that sounds pretty good

i will post delphi7 code here if you want it (please reply if you do) which you can pop in a dll (dont ask me how) and it will terminate the process (provided you give it the window caption(which must be unique))
