Keeping ListView Items Sorted as they update

[NerdFencer]

I am writing a program sort of like Task Manager but different. I have started with the Users tab, but have encountered a problem. After the update routine runs, the items loose their order. What is the best way to maintain the sort order?

This is the file that the problem is in

expandcollapse popup

#include-once
#Include <GuiListView.au3>
#include "InfoStore.au3"

Global $UserTab
Global $UserTabItems[3]
Global $UsersContent[3][6]

Func UsersPopulate()
    Local $temp
    ReDim $UsersContent[$LoggedOnUsers[0][0]][6]
    For $i = 1 To $LoggedOnUsers[0][0]
        $temp = UsersStats($LoggedOnUsers[$i][1])
        $UsersContent[$i-1][0] = $LoggedOnUsers[$i][1]
        $UsersContent[$i-1][1] = $temp[0]
        $UsersContent[$i-1][2] = $temp[1]
        $UsersContent[$i-1][3] = $temp[2]
        $UsersContent[$i-1][4] = $LoggedOnUsers[$i][2]
        $UsersContent[$i-1][5] = $LoggedOnUsers[$i][0]
    Next
EndFunc

Just call this function:

_GUICtrlListView_SortItems($hWndFrom, DllStructGetData($tInfo, "SubItem"))

After your updates are done... Instead of the DllStruct... part just put the column index you're sorting your list by.

I cant seem to get this to work, can you post an example?

_GUICtrlListView_InsertColumn($hListView, 0, "Column 1", 100)

Sleep(2000)

ToolTip("SORTED")
