Multiple instances of the same script .. wont work any longer Topic is solved

[Jovannb]

Hi

I've one (A) script which calls another one (Sccript (B) with different start parameter). Everything worked well for years, multiple instances of (B) where there (some kind of messaging app with GUI's), no issue.
Now I changed (B) to another type of data gathering (from .accdb-File-Access to MySQL-Query).

As of now, (A) starts (B) with parameterset XYZ, later (A) starts (B) with parameterset ABC, then the first instance of (B) with YXZ gets killed and its GUI diappears - it is impossible to run more then one process of (B) simultaneously.

In that (B) there ist

Code: Select all

#singleinstance off

at top, I tried

Code: Select all

#Singleinstance, off

same issue.

I tried to replace my script (B) by

Code: Select all

#SingleInstance Off	
mypid:=DllCall("GetCurrentProcessId")
msgbox, ,%mypid%, %a_now%
return

works well. That original (B) script has 500 lines, too many to post.

How about that ?

Hallo,
I have no idea about "from .accdb-File-Access to MySQL-Query"
but AHK: Ansi, 32-bit! Is that still allowed?

inbetween I found, that I do have the same issue with former (unchanged) release of my script (B) as well.
Is it imaginable that there is a relation with latest Windows Update (now on Win10 20H2(Build 19042.928) ??

Hi

@Rohwedder: therewith I mean, that my B-Script reads all it's data from an .accdb-file and now, because of the situation that many of us are in homeoffice (because of Covid), thats f... slow over VPN. Now I changed that all from .accdb-Files as databas to an MySQL-Server system which is app 20 times faster than that .accdb-file based database.

The issue with that apprently not working directive

Code: Select all

#singleinstance off

is/was a failure in an included ahk-library file. Script B works, but one instance at a time only. Now I excluded that (dismissed

Code: Select all

#incude nixisifx.ahk

) an now my script B is callable with mutliple instances.
