Help with ListView Items

[pl123]

I'm trying to make the total amount of RAM, pagefile, and virtual show in a ListView, so I used MemGetStats (), and setting the values for the arrays [1],[3],[5]:

$MemStats = MemGetStats ()
$MemStats[1] = $TotalPhysRAM
$MemStats[3] = $TotalPagefile
$MemStats[5] = $TotalVirtual

Then, I'm adding them to the ListView:

Global Const $LeftBorder = 10 ; Left 'margin' size

$MainWindow = GUICreate ($GUITitle, 400, 450)
GUISetState (@SW_SHOW, $MainWindow)
WinSetOnTop ($GUITitle, "", 1)
GUICtrlCreateTab (5, 5, 390, 25)

---- omitted ----

$Tab[1] = GUICtrlCreateTabItem ("Computer Specs")
GUICtrlCreateLabel ("******************", $LeftBorder, 35)
GUICtrlCreateLabel ("******************", $LeftBorder, 50)
GUICtrlCreateLabel ("————————————————————————————————————————————————————————————————", $LeftBorder, 62) ; divider line

$MemStats = MemGetStats ()
$MemStats[1] = $TotalPhysRAM
$MemStats[3] = $TotalPagefile
$MemStats[5] = $TotalVirtual

$SpecsList = GUICtrlCreateListView ("****************|Value", $LeftBorder, 75, 380, 300)
GUICtrlCreateListViewItem ("Total Physical RAM|" & $TotalPhysRAM & "", $SpecsList)
GUICtrlCreateListViewItem ("Total Pagefile|" & $TotalPagefile & "", $SpecsList)
GUICtrlCreateListViewItem ("Total Virtual Memory|" & $TotalVirtual & "", $SpecsList)

However, the three items do not show up on the list view thingy. Is there anything wrong? Thanks! =)

pl123,

Is there anything wrong?

I am afraid so!

MemGetStats returns an array already filled with the data. By using this code:

$MemStats = MemGetStats ()
$MemStats[1] = $TotalPhysRAM
$MemStats[3] = $TotalPagefile
$MemStats[5] = $TotalVirtual

you are replacing the data you have obtained with the contents of those 3 variables - which as you have not declared them is an empty string. Hence nothing to display in the ListView.

What you need to do is reverse the order of the assignation statements like this:

$MemStats = MemGetStats ()
$TotalPhysRAM = $MemStats[1]
$TotalPagefile = $MemStats[3]
$TotalVirtual = $MemStats[5]

and you will find that your ListView magically fills with the data.

Hallo)

pl123 Personally i like Listview

Here is my code:

expandcollapse popup

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <ListViewConstants.au3>
#include <WindowsConstants.au3>
#include <GuiListView.au3>

Global $avaray

$Form1 = GUICreate("Test Programm", 510, 255, 389, 325)
$ListView1 = GUICtrlCreateListView("Memory Load (%)" &  "|" &"Total physical RAM" &  "|" &"Available physical RAM" &  "|", 80, 40, 361, 137)
$Button1 = GUICtrlCreateButton("Re Scan", 96, 208, 89, 25, $WS_GROUP)
$Button3 = GUICtrlCreateButton("Delete All Items", 344, 208, 89, 25, $WS_GROUP)


$hcontextmenu=GUICtrlCreateContextMenu($ListView1)
$contextmenu_item1=GUICtrlCreateMenuItem("Get Memory Load  in (%)",$hcontextmenu)
GUICtrlCreateMenuItem("",$hcontextmenu)
$contextmenu_item2=GUICtrlCreateMenuItem("Get Total physical RAM",$hcontextmenu)
GUICtrlCreateMenuItem("",$hcontextmenu)
$contextmenu_item3=GUICtrlCreateMenuItem("Get Available physical RAM",$hcontextmenu)
GUICtrlCreateMenuItem("",$hcontextmenu)
$contextmenu_item4_get_all=GUICtrlCreateMenuItem("Get All in One :P",$hcontextmenu)
GUISetState(@SW_SHOW)



_getmem()





While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1;Rescan Mem and Populate it To Listview
        $avaray=""
           _GUICtrlListView_DeleteAllItems($ListView1)
            _getmem()
        Case $Button3
             _GUICtrlListView_DeleteAllItems($ListView1)
             $emptymsg="Listview Emptied!"
             $asnwer=MsgBox(65,$emptymsg,$emptymsg & "Would you like Rescan Mem and Polulate Listview?",15)
             If $asnwer="1" Then
                 _getmem()
                 EndIf




         Case $contextmenu_item1
             $i="0"
             MsgBox(64,"",_GUICtrlListView_GetItemText(GUICtrlGetHandle($ListView1),_GUICtrlListView_GetSelectedIndices($ListView1),$i))
         Case $contextmenu_item2

         Case $contextmenu_item3
             $i="2"

             MsgBox(64,"",_GUICtrlListView_GetItemText(GUICtrlGetHandle($ListView1),_GUICtrlListView_GetSelectedIndices($ListView1),$i))

            Case $contextmenu_item4_get_all
        MsgBox(64,"","Memory Load (%) " &_GUICtrlListView_GetItemText(GUICtrlGetHandle($ListView1),_GUICtrlListView_GetSelectedIndices($ListView1),0)  & @CRLF & _
         "Total physical RAM " &   _GUICtrlListView_GetItemText(GUICtrlGetHandle($ListView1),_GUICtrlListView_GetSelectedIndices($ListView1),1) & @CRLF & _
          "Available physical RAM " & _GUICtrlListView_GetItemText(GUICtrlGetHandle($ListView1),_GUICtrlListView_GetSelectedIndices($ListView1),2))


;

    EndSwitch
WEnd


Func _getmem()


    $avaray=MemGetStats()
    _populate()

    EndFunc ;==> _getmem()




Func _populate()
    GUICtrlCreateListViewItem($avaray[0] & "|" & $avaray[1] & "|" & $avaray[2],$ListView1)
    EndFunc ; ==>_populate()
