not enough information to answer. give us code that can be compiled and tested along with a CLEARLY defined process about what you are doing and why. Else don't expect much in the way of help.

 

and put the global definition of the control at the TOP of your script so it's defined before you call it from code.

CoProcEx.au3 New AutoIt v3 Script.au3

Simply insert code in the post! ;)

Why would the new thread know anything about the GUI controls?
Doubt it does as it is a separate process, so you would have to use Controlxxx() functions like you would when automating a different program. \

Thank you jos for correcting my post 🥰

I want each multiprocess to receive a different listview data, how can each multiprocess get the listview data

[argumentum]

#include <ListViewConstants.au3> ; add these to stop the error popup
#include <StructureConstants.au3> ; add these to stop the error popup
#include "CoProcEx.au3"
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <GUIListView.au3>

 

[joanex]

I want to assign data from listview to another process

[argumentum]

ok, you could use https://www.autoitscript.com/forum/topic/197277-_arrayfromstring/ 
to send/receive the array via IPC

 

[joanex]

I still don't get what you mean, can you put it in my project?

[argumentum]

no
