 Posted: Tue Dec 04, 2007 4:47 pm Post subject: SingleInstance, Ignore and command line parameters? |
 |
|
Because of performance issues, I want to keep a script unreplaceable by using | Code: | | #SingleInstance Ignore |
I discovered that in this mode it seems not possible to receive command line parameters if the script is called again. Is there any way to get around this?
Thanks in advance,
Rob |

so you are telling it to not start the new script, but you do want the new script's parameters?
it would be better to either change how you are calling the script, or let the second script run, but if it detects another copy, IPC over the items you want, then close.

| Code: | #Singleinstance off
#persistent
SetTitleMatchMode 2
DetectHiddenWindows on
OnMessage(0x313, "CommandPass")
WinGet, id, list, %a_scriptname%
if id3
{
; Third Instance, user error: ignore.
exitapp
return
}
if id2
{
; Second Instance, submit parameters and desist
PostMessage, 0x313, 403, %1%, , ahk_id %id1%
exitapp
}
else if id1
{
; First Instance, initiate routines pending user direction
}
return
CommandPass(wParam, lParam, msg)
{
; Render new parameters and subsume
} |
Here's an adaptation of one of my early scripts with the guts cut out. Of course, you would have to fill in the rest of the script, but you should get the idea. The WinGet command gets a list of all current processes with the same name as the script (with title match on mode 2, so be careful about using the script while editing it in notepad) then , if it detects itself as the second copy of the script, it notifies the first copy of the script via the "PostMessage" function. You'd have to do some tailoring to pass non-numeric parameters this way, but it's not difficult.
Basically, the above code can make different instances of a script perform dofferent actions.

Sorry, I donŽt understand: what does IPC mean?
Thanks to you both for your efforts, but I would really like to avoid starting any second script since this will take a (little) while. I think IŽll explain my case in more detail:
I am using a MS keyboard with this @!#% F-Lock key and want to eliminate the alternate key binding of the function keys which is active by default. Since it is not possible at all to remap them to another key code but only to assign a program, I thought of writing a small script which only sends a key stroke (that corresponds to the function key that lies on the same key) and assign it to the alternate function key. Right now, my script looks like this and works quite well:
| Code: | | SendInput, {Blind}%1% |
How smaller can it be? I compiled it as SendKey.exe and assign this command line to every alternate function key with the corresponding function key number:
"SendKey.exe {F1}"
So, for every press of an alternate function key, the script is loaded and executed. Sometimes loading the script takes a while (may be due to heavy use of the hard disk) and so the key stroke is sent with a noticable delay. This is why I would like to reuse an already running script and only pass the new parameters to it.
If you know of an alternate (better) way to accomplish the main task, I would really be thankful! |

IPC in this case refers to majkinetor's Interprocess communication module.
considering your circumstances, you may be interested in adapting the DDE server posted in the S&F section of the forum. That may help.

DDE sounds like an interesting approach but I really have no clue how to send a DDE message from the command line - I think this is what I would have to do if I donŽt want to start a program at the press of a function key  |

DDE is suitable if you want Explorer to send messages to your script when the user executes a verb on a file (e.g. via double-click or the context menu.) However, file types must be registered (in the registry!) for this. You can manually initiate a DDE connection, but majkinetor's IPC module is generally much easier to use.
DDE Server (for single-instance file association) [std-lib]
(There's also a better solution than DDE, using COM, on pages 3 & 4. Look for "AutoHotkeyVerb".)
If the command-line args aren't simply file-names, I'd go with majkinetor's IPC module.
Can you assign your function keys to documents? For instance, you could create a file type ".ahkcmd" and register that with DDE or IDropTarget (aka "AutoHotkeyVerb".) Then create (empty) .ahkcmd files, like F1.ahkcmd. When the file is launched, Explorer should send its name to the running script, which can then interpret it as a command. |

Hm... Interesting idea: sending a key by assigning a file extension 
IŽll give a try at the weekend. If anything goes wrong, youŽll read me again 
Thanks for your suggestions,
