OneInstance DLL

This is a remake of my old version. I remade it in C++.

http://technosoftnet...InstanceDLL.zip

This DLL allows you to only let one instance of your game run at once.

[ChIkEn AtE mY dOnUtS]

if u rename is camdinstance.dll it would be 10/10

but 9/10 now =D
good remake

[Mousier Goatee]

Nice!
I have seen requests for something like this come up in topics more than once-
a very useful DLL.

[ChIkEn AtE mY dOnUtS]

try to run the example twice at once...

[Shinnoki]

Funny thing roach, i have another problem with one of ur next DLLs (this one). The first one was my mistake, but i dunno where the problem is here...

[Diveloperz]

Could be useful, thanks roach.

<{POST_SNAPBACK}>

IF you want the user to stop running the same program twice at the same time

[Da-Huntha]

got the same error as shinnoki

[pinguinpanic]

THat problem mostly pops up when you didn't extract it.

Good job Roach, might be usefull for online games for making sure there's no multiple logging

[Da-Huntha]

xcept that I did extract it, just like Shinnoki did.

<{POST_SNAPBACK}>

duh, look at the screenshot, does it look like it's not extracted??!!

[Dregnought]

Assuming that this dll was remade for gm 6.1, try downlaoding gm6.1 and try again. There are a few differences, some could be creating this error...

[Da-Huntha]

I have GM 6.1, and I'm pretty sure a DLL like this does work on 6.0 too.

[NJCatch22]

It doesn't work. I got version 6.1 and the same error happends while trying the test example.

[Dregnought]

I'm not sure if Roach will allow this (if not, just get one of the mods to delete it) but an updated version with extras can be found here
Host 1
Host 2
Host 3

Enjoy.

I don't know why you people are having troubles... but try this, it does have one or two things different.

[NJCatch22]

Nope. Even this updated version doesn't work.

From the log file :

ERROR in
action number 1
of Create Event
for object object0:

Error defining an external function.

Do we need an additionnal .dll or is having only OneInstance.dll fine?

Maybe it's because I only tried the example provided with the download and did not try to program my own game.

If this could get fixed & is proven stable, I will surely get it for my games since having 2 instances of the same game can really lead to problems (if you use the same files to store data and both games access it at the same moment, etc.).

[Dregnought]

I can't help you then. It also doesn't make sence...

[hawthorneluke]

the links broken, can anyone point me to where i can get this dll?

[Matt13]

PM roach instead of bumping old topics like this.

Thanks,

Matt

Its possible to do this with a single registry value

[Marchal_Mig12]

Nice very useful
10/10

[PLAY: More]

Its possible to do this with a single registry value

<{POST_SNAPBACK}>

PLEASE do not bump old topics. And we all know that, but a lot of people don't like games messing with their registry. Also, in the event of an emergency exit (a.k.a. Ctrl+Alt+Delete) the Game End event is not triggered and the game becomes unusable.
So it is useful.

[Gameblasterproductions]

How come it wont let me download it? I takes me to an expired godaddy domain. I REALLY need this dll

[molloyboy08]

did you even bother to read roach's sig
"I've recently changed my domain names. Change "technosoftnet.com" to "wowthatsawesome.com" and all of my links will work. Thanks!"
http://wowthatsaweso...InstanceDLL.zip
would be the correct link

[Big J]

Wow, 4 year old topic.

I hate to do this... but...

I found a flaw. I built an executable from the example and discovered that by dragging a file onto the game's icon, I can bypass it and run multiple instances of it.

EDIT:
I added an else condition to the script and discovered that it was bypassed because the DLL didn't exist. (the else condition was triggered and the game ended)

var OI_Search, OI_Set;

global.OI_Handle = -1;
global.OI_Dll = argument0;
if (file_exists(global.OI_Dll))
{
    if (argument1 != "")
    {
        OI_Search = external_define(global.OI_Dll, "search", 1, 0, 1, 1); 
        OI_Set = external_define(global.OI_Dll, "set", 1, 0, 1, 1);
        if (external_call(OI_Search,argument1) == 0)
        {
            global.OI_Handle = external_call(OI_Set, argument1);
        }
        else
        {
            OI_Stop(argument1, argument2);
        }
    }
}
else
{
    game_end();
}

I guess there isn't a problem after all.

The download link doesn't work. I'm getting tired of all these broken links
