error in WinAPIInternals.au3

[topten]

I get a strange error in WinAPIInternals.au3

AutoIt3\Include\WinAPIInternals.au3" (440) : ==> Subscript used on non-accessible variable.:
$__g_vEnum[$__g_vEnum[0][0]][0] = $hWnd
$__g_vEnum^ ERROR

The script does what I want but it breaks after this error.

I wasnt having the same error before. I think may be some update?

[mLipok]

show how you use it.

 

EDIT:

The script does what I want but it breaks after this error.

Remark:
it breaks before or on this error "message", as this error which you see is only an message to you after issue occurs.

#RequireAdmin
#include "_shellExecuteHidden.au3"

$hWinHiddenApp = _shellExecuteHidden("C:\Dir1\dunno.exe")

 

 

PS  https://www.autoitscript.com/forum/topic/156155-_shellexecutehidden-allow-no-windows-to-become-visible/

[mLipok]

can you provide _shellExecuteHidden.au3

or at least _shellExecuteHidden function ?

This is the whole udf

; #FUNCTION# ====================================================================================================================
; Name ..........: ShellExecuteHidden
;
; Description ...: runs a process on another winApi-desktop, so that none of its windows ever get visible, but can be automated by window messages and other technologies.
;                  The difference to shellExecute( ... , ... , @SW_HIDE ) is, that no just the first, but any windows from the created process will stay totaly isolated from user input and graphics
;
; Syntax ........: ShellExecuteHidden($filepath[, $parameters = "" [, $returnType = 1 [, $waitingOption = -1 ]]])
;
; Parameters ....: $filepath       - the file to run
;
;                  $returnType     =           0  >>  returns window handle of toplevel window of the started process
;                                                     even if its window is "hidden" (would not be visible on normal desktop)
;                                  =           1  >>  returns window handle of toplevel window of the started process
;                                  =           2  >>  returns process id (PID) of the started process
;
;
;                  $waitingOption  =          -2  >> dont wait (not recommended for window handles, as they need some time to appear even if the program is loading fast)
;                                  =          -1  >> wait 1000 milliseconds for windows to "appear" but dont wait for processes to finish (compromise)
;                                  =           0  >> wait for the process to finish or the window to appear
;                                  =         <x>  >> wait <x> milliseconds for the process to finish or the window to appear (see "$returnType" )
;
; Return values .: windowHandle or ProcessID

I use it like this:

#RequireAdmin
#include "_shellExecuteHidden.au3"

$hWinHiddenApp = _shellExecuteHidden("c:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe")

And new AcroRd32.exe is now in my Task Manager and I do not see any Acrobat User Interface.

Also I tried with other application like TotalCmd all looks ok.

Question: Which AutoIt version you are using?

 

[guinness]

I am detecting no bug either.

@topten

Are you sure you are admin ?

#RequireAdmin
#include "_shellExecuteHidden.au3"
MsgBox(0, '', IsAdmin())
$hWinHiddenApp = _shellExecuteHidden("c:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe")

I have reinstalled AutoIt with all the included and the problem has disappeared. Thank you very much for your support people

Still would have been good to know your AutoIt version i.e. @AutoItVersion
