Hi,

I'm playing with this code and realized that the GUICtrlCreateListViewItem return 0.

Am i doing something wrong here?

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <Array.au3>
#include <WindowsConstants.au3>
Global $Processes[1], $Processes_Run = False
$MGui = GUICreate("Simple Task Manager", 615, 438, 192, 124)
$MLV = GUICtrlCreateListView("Process Id|#No|Virtual Size|Description|Command Line|Executable Path", 0, 42, 615, 396)
_ListProcess()
GUISetState(@SW_SHOW)
_ArrayDisplay($Processes)

Func _ListProcess()
Local $i = 0
Local $wbemFlagReturnImmediately = 0x10
Local $wbemFlagForwardOnly = 0x20
Local $Wbem = ObjGet("winmgmts:\\localhost\root\CIMV2")
Local $Process = $Wbem.ExecQuery("SELECT * FROM Win32_Process", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
For $Proc In $Process
$i += 1
If $Processes_Run Then
If $i > $Processes[0]-1 Then
ReDim $Processes[$i+1]
$Processes[$i] = GUICtrlCreateListViewItem($Proc.Caption &'|'& $i & '|'& $Proc.ProcessId &'|'& $Proc.VirtualSize &'|'& $Proc.HandleCount &'|'& $Proc.CommandLine &'|'& $Proc.ExecutablePath, $MLV)
Else
GUICtrlSetData($Processes[$i], $Proc.Caption &'|'& $i &'|'& $Proc.ProcessId &'|'& $Proc.VirtualSize &'|'& $Proc.HandleCount &'|'& $Proc.CommandLine &'|'& $Proc.ExecutablePath, $MLV)
EndIf
Else
ReDim $Processes[$i+1]
$Processes[$i] = GUICtrlCreateListViewItem($Proc.Caption &'|'& $i &'|'& $Proc.ProcessId &'|'& $Proc.VirtualSize &'|'& $Proc.HandleCount &'|'& $Proc.CommandLine &'|'& $Proc.ExecutablePath, $MLV)
EndIf
Next
If Not $Processes_Run Then $Processes_Run = True
$Wbem = 0
$Process = 0
EndFunc

While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
ExitLoop
EndSwitch
WEnd

You would require #RequireAdmin

Test this

#RequireAdmin
#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <Array.au3>
#include <WindowsConstants.au3>
Global $Processes[1], $Processes_Run = False
$MGui = GUICreate("Simple Task Manager", 615, 438, 192, 124)
$MLV = GUICtrlCreateListView("S.No|Process Id|#No|Virtual Size|Description|Command Line|Executable Path", 0, 42, 615, 396)
_ListProcess()
GUISetState(@SW_SHOW)
;~ _ArrayDisplay($Processes)

Func _ListProcess()
Local $i = 0
Local $wbemFlagReturnImmediately = 0x10
Local $wbemFlagForwardOnly = 0x20
Local $Wbem = ObjGet("winmgmts:\\localhost\root\CIMV2")
Local $Process = $Wbem.ExecQuery("SELECT * FROM Win32_Process", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
For $Proc In $Process
ReDim $Processes[$i + 1]
$Processes[$i] = GUICtrlCreateListViewItem($i & "|" & $Proc.Caption & '|' & $i & '|' & $Proc.ProcessId & '|' & $Proc.VirtualSize & '|' & $Proc.HandleCount & '|' & $Proc.CommandLine & '|' & $Proc.ExecutablePath, $MLV)
If $Processes[$i] = 0 Then ConsoleWrite("0 at " & $i & @CR)
$i += 1
Next
If Not $Processes_Run Then $Processes_Run = True
$Wbem = 0
$Process = 0
EndFunc ;==>_ListProcess

While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
ExitLoop
EndSwitch
WEnd

My code:

PredictText: Predict Text of an Edit Control Like Scite. Remote Gmail: Execute your Scripts through Gmail. StringRegExp:Share and learn RegExp.

Run As System: A command line wrapper around PSEXEC.exe to execute your apps scripts as System (LSA). Database: An easier approach for _SQ_LITE beginners.

MathsEx: A UDF for Fractions and LCM, GCF/HCF. FloatingText: An UDF for make your text floating. Clipboard Extendor: A clipboard monitoring tool. 

Custom ScrollBar: Scroll Bar made with GDI+, user can use bitmaps instead. RestrictEdit_SRE: Restrict text in an Edit Control through a Regular Expression.

Are you using a 64-bit OS ?

Sorry i did some tests and found that after receiving the Admin rights the ConsoleWrite didn't work on my computer..

I tried with msgbox and it still gives me 0

need to do some more test..!

Tests in vain

Maybe there were a lot of items, I removed the Executable path data and everything seems to be okay !!

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <Array.au3>
#include <WindowsConstants.au3>
Global $Processes[1], $Processes_Run = False
$MGui = GUICreate("Simple Task Manager", 615, 438, 192, 124)
$MLV = GUICtrlCreateListView("S.No|Process Id|#No|Virtual Size|Description|Command Line|Executable Path", 0, 42, 615, 396)
_ListProcess()
GUISetState(@SW_SHOW)
;~ _ArrayDisplay($Processes)

Func _ListProcess()
Local $i = 0
Local $wbemFlagReturnImmediately = 0x10
Local $wbemFlagForwardOnly = 0x20
Local $Wbem = ObjGet("winmgmts:\\localhost\root\CIMV2")
Local $Process = $Wbem.ExecQuery("SELECT * FROM Win32_Process", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
For $Proc In $Process
ReDim $Processes[$i + 1]
$Processes[$i] = GUICtrlCreateListViewItem($i & "|" & $Proc.Caption & '|' & $i & '|' & $Proc.ProcessId & '|' & $Proc.VirtualSize & '|' & $Proc.HandleCount & '|' & $Proc.CommandLine , $MLV)
ConsoleWrite($i & ":" & $Processes[$i] & @CR)
$i += 1
Next
If Not $Processes_Run Then $Processes_Run = True
$Wbem = 0
$Process = 0
EndFunc ;==>_ListProcess

While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
ExitLoop
EndSwitch
WEnd

Maybe somewhat similar could be a workaround..

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <Array.au3>
#include <WindowsConstants.au3>

Global $Processes[1], $Processes_Run = False
$MGui = GUICreate("Simple Task Manager", 615, 438, 192, 124)
Global $hLV = GUICtrlCreateListView("S.No|Process Id|#No|Virtual Size|Description|Command Line|Executable Path", 0, 42, 615, 396)
_ListProcess()
GUISetState(@SW_SHOW)
;~ _ArrayDisplay($Processes)

Func _ListProcess()
Local $i = 0
Local $wbemFlagReturnImmediately = 0x10
Local $wbemFlagForwardOnly = 0x20
Local $Wbem = ObjGet("winmgmts:\\localhost\root\CIMV2")
Local $Process = $Wbem.ExecQuery("SELECT * FROM Win32_Process", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
For $Proc In $Process
_GUICtrlListView_AddItem($hLV, $i)
_GUICtrlListView_AddSubItem($hLV, $i, $Proc.Caption, 1)
_GUICtrlListView_AddSubItem($hLV, $i, $Proc.ProcessId, 2)
_GUICtrlListView_AddSubItem($hLV, $i, $Proc.VirtualSize, 3)
_GUICtrlListView_AddSubItem($hLV, $i, $Proc.HandleCount, 4)
_GUICtrlListView_AddSubItem($hLV, $i, $Proc.CommandLine, 5)
_GUICtrlListView_AddSubItem($hLV, $i, $Proc.Caption, 6)
$i += 1
Next
$Wbem = 0
$Process = 0
EndFunc ;==>_ListProcess

While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
ExitLoop
EndSwitch
WEnd

Finally the error was one extra column was added.

This would solve the problem

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <Array.au3>
#include <WindowsConstants.au3>
Global $Processes[1], $Processes_Run = False
$MGui = GUICreate("Simple Task Manager", 615, 438, 192, 124)
$MLV = GUICtrlCreateListView("S.No|Process Id|#No|Virtual Size|Description|Command Line|Executable Path", 0, 42, 615, 396)
_ListProcess()
GUISetState(@SW_SHOW)
;~ _ArrayDisplay($Processes)

Func _ListProcess()
Local $i = 0
Local $wbemFlagReturnImmediately = 0x10
Local $wbemFlagForwardOnly = 0x20
Local $Wbem = ObjGet("winmgmts:\\localhost\root\CIMV2")
Local $Process = $Wbem.ExecQuery("SELECT * FROM Win32_Process", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
For $Proc In $Process
ReDim $Processes[$i + 1]
$Processes[$i] = GUICtrlCreateListViewItem( $i & _
"|" & $Proc.Caption & _
'|' & $Proc.ProcessId & _
'|' & $Proc.VirtualSize & _
'|' & $Proc.HandleCount & _
'|' & $Proc.CommandLine & _
'|' & $Proc.ExecutablePath, $MLV )
If $Processes[$i] = 0 Then ConsoleWrite("0 at " & $i & @CR)
$i += 1
Next
If Not $Processes_Run Then $Processes_Run = True
$Wbem = 0
$Process = 0
EndFunc ;==>_ListProcess

While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
ExitLoop
EndSwitch
WEnd
